Angiolipoma is a common benign tumor with a characteristic vascular component that usually occurs in subcutaneous tissue. Although lipomas are frequently encountered at colonoscopy as submucosal tumors, angiolipomas are rarely found in the gastrointestinal tract including the large intestine. Here we report a 77-year old Japanese man who underwent transanal resection of a tumor that was diagnosed tentatively as a leiomyoma. Histologically, the tumor consisted of mature fat cells and blood vessels. Immunohistochemically, the tumor cells were negative for c-kit and HMB-45, which are consistently expressed in tumors such as gastrointestinal stromal tumor and angiomyolipoma. The tumor was therefore diagnosed as an angiolipoma. This is thought to be the first case report of a surgically resected angiolipoma of the rectum.

Acute ischemic proctitis is a rare pathological condition. We report here a patient presented with massive rectal haemorrhage from a bleeding vessel superimposed on an underlying pathology of ischemic proctitis. This case report illustrates the difficulties in making the clinical distinction between ischemic proctitis and other pathological entities. We also discussed the beneficial role of arteriogram with embolotherapy as an effective therapeutic measure in the management of lower gastrointestinal bleeding. The literature on the subject is reviewed.

We report an 11-week-old female who presented with Kawasaki disease (KD) complicated by macrophage activation syndrome (MAS). The infant presented to the hospital with persistent fever, cough, diarrhea, and emesis, among other symptoms. Her condition quickly began to decompensate, and she developed classic features (conjunctivitis, rash, cracked lips, distal extremity edema) prompting a diagnosis of acute KD. The patient was treated with standard therapy for KD including three doses of intravenous immunoglobulin (IVIG), aspirin, and high dose glucocorticoids with no change in her condition. Due to a high suspicion for MAS, high dose anakinra therapy was initiated resulting in dramatic clinical improvements. She also received one dose of infliximab for concern for coronary artery changes, and over the course of several months, anakinra and high dose glucocorticoids were tapered. Nearly complete reversal of echocardiogram changes were observed after 8 months, and the infant is now off all immunosuppressive therapy. In this case report, we briefly review the importance of early recognition of MAS in pediatric patient populations with rheumatic diseases, and we suggest early initiation of anakinra therapy as a rapid and effective treatment option.

Synchronous occurrence of adenocarcinoma and mucosa associated lymphoid tissue (MALT) lymphoma of colon is rare, and its presence with coexisting tuberculosis is still rarer. To our knowledge, this may be the first case report. In the present report, we describe a 43-year-old female who presented with a history of abdominal pain, fever, loss of weight and loss of appetite. Colonoscopy showed a large ulceroproliferative mass arising from the caecum, biopsy of which showed it to be adenocarcinoma of the colon. A right hemicolectomy was performed and microscopic study of the colon revealed tuberculosis and synchronous adenocarcinoma with lymphoma. Eight of sixteen lymph nodes showed tuberculosis and three of sixteenpericoloniclymphnodes showed metastatic deposits. Immunostains further confirmed the tumour to be adenocarcinoma with MALT lymphoma. We would like to highlight the diagnostic challenges arising from the multi-faceted presentations of these three conditions.

Though an association between autoimmune diseases and sick sinus syndrome has been reported, there has been no report on the association of hypopituitarism and sick sinus syndrome. Herein, we provide the first case report of hypopituitarism accompanying sick sinus syndrome in a 51-year-old woman presented to our hospital with syncope due to cardiac arrest. The patient was successfully managed by pacemaker installation and hormone replacement therapy.

An increasing number of reports reveal the safety and efficacy of catheter ablation for atrial fibrillation therapy even in patients with a history of prosthetic heart valve. This case report presents a 60 year old female patient who had a prosthetic mitral paravalvular leak as a complication of radiofrequency ablation. Surgery revealed a 15 mm hole and three broken knots in the posterolateral mitral annulus. This report demonstrates radiofrequency ablation for atrial fibrillation in patients with prosthetic mitral valve may cause a paravalvular leak likely as a result of thermal injury. Moreover, patient can be asymptomatic at first. The clinician should keep in mind such complication and the patient should be evaluated in terms of paravalvular leakage.

Introduction: Invasive aspergillosis of the paranasal sinuses is a rare disease and often misdiagnosed; however, its incidence has seen substancial growth over the past 2 decades. Definitive diagnosis of these lesions is based on histological examination and fungal culture. Case Report: An 81-year-old woman with a history of pain in the left maxillary region is presented. The diagnosis was invasive maxillary aspergillosis in immunocompetent patient, which was successfully treated with voriconazole and surgical debridement. Possible clinical manifestations, diagnostic imaging techniques and treatment used are discussed. Since the introduction of voriconazole, there have been several reports of patients with invasive aspergillosis who responded to treatment with this new antifungal agent. Conclusions: We report the importance of early diagnosis and selection of an appropriate antifungal agent to achieve a successful treatment.

Spondylocostal dysostosis (SCDO) is rare anomaly caused due to flawed embryological development of the axial skeleton during preliminary stages of gravidity, characterized by malformed vertebral column and ribs, abridged thorax and kyphoscoliosis. This entity was also reported as a “Jarcho–Levin syndrome” eponym by erstwhile authors, before the introduction of genetic based classification. A literature review showed only three cases of this clinical entity with lipomyelomeningocele. We report the fourth case report of an infant with SCDO with lipomyelomeningocele. His chest X-ray displayed absent left side 6th–8th ribs with peculiar fan like configuration, making the heart vulnerable to any direct injury. Special care has to be taken for such patients who need surgical procedure in the prone position.

A young gentleman presented with difficulty in breathing. Computed tomography (CT) scan showed a huge mass located between the heart and stomach, which might have rooted in the diaphragm. Magnetic resonance imaging (MRI) with enhanced three dimensional construction showed a lobulated, heterogeneous soft tissue mass with short T1 weighted imaging signal and flake long T2-weighted imaging (T2WI). Tumor-enhanced scanning demonstrated heterogeneous contrast enhancement. The preliminary diagnosis was intra-abdominal huge mass and considering sarcoma. Resection was conducted where the base of the tumor was located in the diaphragm oppressing the left liver lobe and heart. The base of the tumor, together with partial surrounding of the diaphragm, pericardium base, and the left lateral hepatic segment, was resected. The defect in the diaphragm and pericardium was repaired by patching, and thoracic close drainage and abdominal drainage were placed following the surgical operation. The pathological report showed giant solitary fibrous tumor (SFT). This case report may provide a reference resource for the diagnosis and treatment of SFT located in the diaphragm.

This is the first case report in Oman and the Gulf region of a 17-β-hydroxysteroid dehydrogenase type 3 (17-β-HSD3) deficiency with a novel mutation in the HSD17B3 gene that has not been previously described in the medical literature. An Omani child was diagnosed with 17-β-HSD3 deficiency and was followed up for 11 years at the Pediatric Endocrinology Clinic, Royal Hospital, Oman. He presented at the age of six weeks with ambiguous genitalia, stretched penile and bilateral undescended testes. Ultrasound showed no evidence of any uterine or ovarian structures with oval shaped solid structures in both inguinal regions that were confirmed by histology to be testicular tissues with immature seminiferous tubules only. The diagnosis was made by demonstrating low serum testosterone and high androstenedione, estrone, and androstenedione:testosterone ratio. Karyotyping confirmed 46,XY and the infant was raised as male. Testosterone injections (25mg once monthly) were given at two and six months and then three months before his surgeries at five and seven years of age when he underwent multiple operations for orchidopexy and hypospadias correction. At the age of 10 years he developed bilateral gynecomastia (stage 4). Laboratory investigations showed raised follicle-stimulating hormone...

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder with common comorbidities that include oppositional defiant disorder, conduct disorder, anxiety disorder, and affective disorders. Because of these comorbidities, drug combination treatments and drug-drug interactions are becoming increasingly more frequent. The present case report describes an acute dystonic reaction following the abrupt discontinuation of methylphenidate from a drug regimen with risperidone. The patient experienced acute dystonic reactions on three separate occasions when he forgot to take his methylphenidate medication. The present report informs clinicians about the possible side effects, such as dystonia, when psychostimulant and antipsychotic drug combinations are altered and suggests that the abrupt cessation of stimulants may lead to the development of movement disorders. Therefore, appropriate care is necessary when changing the dose of a drug or abruptly discontinuing a drug from a combination of psychostimulants and antipsychotics.

Primary cutaneous apocrine gland carcinoma, which is a type of sweat gland carcinoma, is an extremely rare type of cancer. Clinical courses of this type of cancer usually progress slowly but can, occasionally, be associated with rapid progression. This case report describes a 53-year-old Korean man with primary cutaneous apocrine gland carcinoma that arose from an apocrine gland in the areola tissue. The patient visited our hospital because of a large, painful chest wall mass beneath the right nipple. The mass had been present for more than eight years but had grown rapidly over the past few months. The patient was initially diagnosed with a benign cystic mass, and we performed a wide excision with a clear margin and without lymph node dissection. The mass was a well-encapsulated cystic lesion that contained old blood material, and there was no invasion into the surrounding tissue. The final pathology showed that the mass was a primary cutaneous apocrine gland carcinoma that arose from the areola apocrine sweat gland, not from the breast parenchymal tissue. Herein, we report an extremely rare chest wall mass unfamiliar to thoracic surgeons.

Central neurocytoma/extraventricular neurocytoma is a central nervous system (CNS) tumor composed of uniform round cells with neuronal differentiation. The typical lesions of central neurocytoma/extraventricular neurocytoma are at the interventricular foramen of the lateral ventricles (central neurocytoma) or brain parenchyma (extraventricular neurocytoma). Mature teratoma is a benign germ cell tumor commonly found in young women. Herein, we report a 24-year-old female with neurocytoma in a mature teratoma of the right ovary. The histological examinations showed mature epidermis, skin appendages, adipose and bone tissues in the tumor; microscopic foci of immature cartilage tissues were also found in some parts. In addition, massive solid sheets and uniform round tumor cells were found in the neuroectodermal tissues, with the formation of neuropil-like islands. Immunohistochemical examinations showed that the tumor cells were synaptophysin- and NeuN-positive but GFAP-negative. Based on these findings, the woman was diagnosed with neurocytoma arising from mature ovary teratoma, with microscopic foci of immature cartilage tissues. This is the fourth case report of neurocytoma outside the CNS to date.

Intracranial extraskeletal myxoid chondrosarcoma is extremely rare, with only seven patients previously reported. We present a case report of a 21-year-old woman admitted for weakness in her right extremities and symptoms of increased intracranial pressure. Magnetic resonance imaging (MRI) revealed hydrocephalus and a well-enhanced large mass around her left thalamus. A left parietal craniotomy and a cortisectomy at the superior parietal lobule were performed. Total surgical resection was also performed, and pathology results confirmed an extraskeletal myxoid chondrosarcoma. Postoperative MRI showed no residual tumor, and the patient underwent radiotherapy. After six months of radiotherapy, the patient's headache and weakness had improved to grade IV. This malignant tumor showed high rates of recurrence in previous reports. We here report another occurrence of this highly malignant and rare tumor in a patient treated using total surgical excision and adjuvant radiotherapy.

We report a 24-year-old woman presenting with a relapsed soy-bean-size tender mass at the junction of the soft and hard palate and a history of palatine tumor of small cell carcinoma. Reexcision surgery was performed and histopathological features were consistent. The patient was treated with six cycles of chemotherapy consisting of etoposide and cisplatin. After one year, the patient developed bone metastases and Cushing's syndrome, and successfully recovered with subsequent chemotherapy with irinotecan and cisplatin plus radiotherapy. There was no evidence of recurrence or metastasis for more than three years. Small cell carcinoma originating in the head and neck region has been reported to be highly aggressive and has a poor prognosis. This is the first case report of a patient with relapsed primary small cell carcinoma of the palate and successfully treated with second-line chemotherapy and local radiotherapy.

Treatment for Hodgkin's lymphoma (HL) has resulted in excellent survival rates but is associated with increased risks of secondary therapy-related acute myeloid leukemia (t-AML). Gingival enlargement associated with bleeding and ulceration is the most common rapidly appearing oral manifestations of leukemic involvement. An 8 months pregnant patient reported with generalized gingival enlargement, with localized cyanotic and necrotic papillary areas. Co-relating the hematological report with the oral lesions and her past medical history of HL, a diagnosis of t-AML secondary to treatment for HL was made by the oncologist. As oral lesions are one of the initial manifestations of acute leukemia, they may serve as a significant diagnostic indicator for the dental surgeons and their important role in diagnosing and treating such cases. Furthermore, this case report highlights the serious complication of t-AML subsequent to HL treatment and the important role that a general and oral health care professional may play in diagnosing and treating such cases.

Primitive neuroectodermal tumor (PNET) of the chest wall or Askin's tumor is a rare neoplasm of chest wall. It most often affects children and adolescents and is a very rare tumor in adults. In this case report, we present an Askin's tumor occurred in a 73-year-old male. The patient was admitted with a history of 3-month lower back pain and cough. In computed tomography, there was a lesion with dimensions of 70 × 40 × 65 mm in the superior segment of the lower lobe of the left lung. Positron emission tomography/computed tomography with 18F-flourodeoxyglucose revealed a pleural-based tumor in the left lung with a maximum standardized uptake value of 4.36. No distant or lymph node metastases were present. The patient had gone through surgery, and wedge resection of the superior segment of left lobe and partial resection of the ipsilateral ribs were performed. Pathology report with immunocytochemistry was consistent with PNET and the patient received chemotherapy after that.

Burns to the hand are common in burn victims. These burns often leave complex wounds that require local flaps for coverage. Local flaps are often excluded because they lie within the zone of thermal injury. The purpose of this case report is to report the successful use of a Quaba flap harvested from a previously burned and skin-grafted area. The patient's medical record including pre-operative, intra-operative, and post-operative photographs were reviewed and utilized as sources of data. The patient tolerated the procedure well and was able to return to his previous hand therapy regimen without adverse event and with an acceptable cosmetic result. The Quaba flap can be a safe and effective option for local hand coverage even in previously burned and skin-grafted areas.
