A case of gastric Non-Hodgkin's lymphoma in AIDS patient / 대한내과학회지

Non-Hodgkin's lymphoma (NHL) is the secondary most common tumor in HIV-infected individuals. The AIDS-related lymphomas are a late manifestation of HIV infection and may increase in frequency as patients live longer with highly active antiretroviral therapy and effective prophylaxis of opportunistic infections. Histologically AIDS-related NHL are either high (2/3) or intermediate (1/3) grade lymphoma. We report a case of gastric Non-Hodgkin's lymphoma in AIDS patient. Two years ago, she was diagnosed as HIV-infected individual in public hospital. She presented with epigastric pain and mass-like sensation. Under the impression of gastric cancer, subtotal gastrectomy was done. But, she diagnosed as diffuse large B cell lymphoma by histologic finding, immunohistochemical study. This is the first report of gastric Non-Hodgkin's lymphoma from AIDS patients in Korea.

Direct Invasion of Thyroid Papillary Carcinoma to Esophagus Presenting as an Intraluminal Polypoid Mass Which Causes Hematemesis / 대한소화기내시경학회지

We report an unusual case of metastatic thyroid papillary carcinoma directly invades the esophagus presenting as an intraluminal polypoid mass which causes hematemesis. The patient had a past medical history of thyroid nodule. Physical examination was unremarkable except the palpable thyroid mass. Esophagoscopy and esophagography revealed an intraluminal polypoid mass to the left of the cervical esophagus. Chest computed tomography showed round, homogenous, well-enhancing mass and calcifying thyroid nodule is found in front of the mass. Thyroid lobectomy and partial esophageal resection was performed. Microscopic finding showed typical features of thyroid papillary carcinoma. Metastatic thyroid papillary carcinoma should be included in the differential diagnosis of an intraluminal polypoid esophageal mass, particularly if the patient has a known thyroid tumor.

Three Cases of Autoimmune Thyroid Disease in a Family through Three Generation / 대한내분비학회지

According to recent studies, the immunogenetic factors are thought to be account for a part of the etiopathogenesis of autoimmune thyroid disease. In Korea, there was one report on the relationship between HLA DR5, DR8, B13 and autoimmune thyroid disease. There were also several reports on a familial hereditary transmission of autoimmune thyroid disease in other countries but not in Korea. We describe the occurrence of autoimmune thyroid disease that affected three members of a family through three generations. This is the first report on familial hereditary transmission of autoimmune thyroid disease in Korea. We report on an 80-year-old woman who presented with Hashimoto's thyroiditis, her 53-year-old daughter who had Graves' disease, and her 29-year-old grand-daughter who had Graves' disease. In order to identify the immunogenetic influence in these cases, HLA haplotypes & thyroid autoantibody were studied. HLA DRB3*02 was obseved in each of the patents. HLA DQB1*0301, DR11, DQB1*05031 and DR14 were observed in the two cases. However, HLA B13, DR5 and DR8 were not observed. The patients are currently undergoing follow-up using PTU, methimazole and synthyroid medication.
