A Case of Enteropathy-Type T-Cell Lymphoma Diagnosed by Small Bowel Enteroscopy: A Perspective on Imaging-Enhanced Endoscopy

Enteropathy-type T-cell lymphoma (ETL) or enteropathy-associated T-cell lymphoma is a very rare malignant intestinal tumor. ETL is usually diagnosed by surgery. Endoscopic findings of ETL are not well known, and there are few reports of findings from endoscopy that has been performed only using white light. Additionally, there are no definite treatment guidelines for ETL. Therefore, we report a case of ETL diagnosed by enteroscopy with imaging-enhanced endoscopy and also review recently developed treatment options.

Spontaneous Rupture of a Gastric Stromal Tumor Causing Hemoperitoneum

We describe a 39-year-old man with spontaneous rupture of a gastric stromal tumor causing hemoperitoneum. Ultrasonography showed a large mass broadly abutting the stomach and liver. Computed tomography demonstrated a heterogeneous enhanced mass arising from the stomach and focal perforation of the tumor with hemoperitoneum; endoscopic ultrasonography showed an exophytic heterogeneous mass originating from the gastric muscle layer. Angiography revealed that the right gastric artery was the main artery supplying the tumor. A gastric stromal tumor with bloody fluid in the peritoneal cavity was seen at the laparotomy. The tumor was excised completely, and subsequent histological and immunohistochemical studies indicated that it was a gastric stromal tumor. We report a relatively rare case of gastric stromal tumor causing hemoperitoneum due to spontaneous rupture of the tumor.

A case of metastatic squamous cell carcinoma of the mediastinum with unknown primary tumor / 대한내과학회지

Unknown primary tumor is not an unusual phenomenon. It has been reported that patients with primary unknown cancer constitute 0.5~3.3% of all cancer patients. The most common site of the detected cancer was the lymph node. The locations of the lymph node were cervical, supraclavicular, axillary and inguinal regions. Squamous cell carncer at a metastatic site is found in only approximately 5% of all patients with unknown primary tumors. Especially, squamous cell cancer detected only in mediastinal or hilar lymph nodes is quite rare. We report one case of Metastatic squamous cell cancer of the mediastinum with unknown primary tumor, in which a metastatic survey has not yieled any evidence of further disease. The pathologic finding was representative of squamous cell cancer. A chemotherapy was performed based on the advanced lung cancer for the treatment without surgical approach.

Characteristics of necrotizing fasciitis in three university hospitals in Korea / 대한내과학회지

BACKGROUND: Necrotizing fasciitis is a life threatening severe soft tissue infection primarily involving the fascia and the subcutaneous tissue with thrombosis of the cutaneous microcirculation. The purpose of the study was to analyze the microbiological and clinical characteristics of necrotizing fasciitis in Korea and to suggest adequate antibiotic therapy. METHODS: We retrospectively reviewed medical records of three Soonchunhyang University Hospitals in Seoul, Bucheon and Cheonan. Patients admitted for skin graft or secondary treatment were excluded. Blood cultures were obtained at the time of admission and pus cultures were obtained at the time of first operative debridement. RESULTS: Twenty two patients (16 males, 6 females, 16~82 years old, median age: 59 years old) were enrolled for this study. Fourteen pateints underwent surgical treatment and 2 of them died of necrotizing fasciitis. Gram positive organisms were isolated in 13 cases and gram negative organisms were isolated in 11 cases. Third generation cephalosporin resistant gram negative organisms were isolated in 3 cases. CONCLUSIONS: This study suggest that characteristics of necrotizing fascitis in Korea were; high proportion of aged person, predominance of type 2 necrotizing fascitis and increasing tendency of third generation cephalosporin resistant gram negative bacterial infections. Consequently, initial choice of empirical antibiotics for necrotizing fasciitis should consider 3rd generation cephalosporin resistant gram negative organisms. Prompt surgical debridement and adequate antimicrobial therapy are mandatory for improved survival.

A Case of Pulmonary Sequestration Treated with Arterial Embolization / 결핵및호흡기질환

Pulmonary sequestration is a very rare congenital malformation in which a mass of pulmonary tissue is detached from the normal lung and receives its blood supply from a systemic artery. It may be clinically asymptomatic or it has a wide spectrum of various clinical manifestations. The clinical therapeutic approach is to resect the sequestered lobe to prevent frequent complication such as infection. The arterial embolization of feeding artery is a new technique and a less invasive treatment than conventional surgical removal. We have experienced a 17- year-old male with pulmonary sequestration whose complaints were pain in left lower chest. He was diagnosed by computed tomography and aortography and successfully treated with embolization of feeding artery. We report a case of pulmonary sequestration treated with arterial embolization instead of surgery.

A Case of Henoch-Schonlein Purpura with Small Bowel Hemorrhage Diagnosed by Capsule Endoscopy / 대한소화기내시경학회지

A 23 year-old female patient complained of recurrent abdominal cramps and underwent emergency appendectomy in a private clinic. Two weeks later, she complained of lower GI bleeding and was referred to our hospital. On admission, she had abdominal pain and arthralgia but no hematuria. On physical examination, she was hemodynamically stable but was pale. There was no specific finding in laboratory test, except slightly lower level of blood hemoglobin. EGD revealed no specific findings. Colonoscopy showed fresh blood in the colon with small ulcers and erosions in the ileocecal valve but no source of active bleeding. On third admission day, she developed palpable macular rash initially over her lower legs, ankles, wrist joints and later on anterior abdominal wall. Capsule endoscopy revealed several small and large ulcers and erosions in the entire small bowel with blood clots. She was diagnosed clinically as a case of Henoch-Schonlein purpura through her clinical history and skin lesions. She was administered prednisolone 40 mg/day for a period of one week. Her symptoms, G-I bleeding as well as the skin lesions responded well to steroid therapy and she remained asymptomatic afterwards.

A Case of Thyrotoxic Paraplegia / 대한내분비학회지

Hyperthyroidism may be associated or present with a variety of neuromuscular disorders, including thyrotoxic myopathy, exophthalmic ophthalmoplegia, periodic paralysis and myasthenia gravis. In contrast to muscle, peripheral nerve involvement in hyperthyroidism is exceedingly rare, and has received little attention. Paraplegia-like weakness during severe hyperthyroidism was first described by Charcot in 1889, and called Basedow's paraplegia' by Joffory in 1894. However, there has been no reported case in Korea. A 38-year-old woman was admitted for evaluation of progressive weakness and a gait disturbance. Her endocrinological results were compatible with hyperthyroidism. The polyneuropathy was also confirmed with sequential electrophysiological studies of the nerves and muscles. Drug therapy for hyperthyroidism resulted in resolution of the clinical neurological symptoms and progressive improvement of electrophysiological findings. Hyperthyroidisms are common medical disorders, which are often accompanied by diverse types of neurological and neuromuscular dysfunctions. All of these neurological manifestations are important, as they can serve as important clues to the diagnosis of a thyroid disorder. Furthermore, they are often related to the patient's presenting complaint. Therefore, the physician must be alert to the diverse manifestations of thyroid dysfunction, as they can lead to the diagnosis of potentially serious but treatable disorders. Herein is reported a case of myopathy and neuropathy associated with hyperthyroidism (Basedow's paraplegia), with a review of the literature
