Longlasting Remission of Primary Hepatic Mucosa-associated Lymphoid Tissue (MALT) Lymphoma Achieved by Radiotherapy Alone

Primary hepatic lymphoma is a rare disorder representing less than 1% of all extranodal lymphomas. Histological examination of a primary hepatic lymphoma usually reveals a diffuse large B-cell lymphoma; there have been few reports of primary hepatic mucosa-associated lymphoid tissue (MALT) lymphomas. A 67-year-old man was being treated for a duodenal ulcer; while receiving therapy for the ulcer, a liver mass was incidentally found on abdominal ultrasonography. The pathologic diagnosis of the hepatic mass was an extranodal marginal zone B-cell lymphoma of MALT. The patient underwent radiotherapy with a total of 4,140 cGy delivered. The patient achieved complete remission and has been followed for 6 years with no recurrence of the disease. This report reviews the case of a primary hepatic extranodal marginal zone B-cell lymphoma of MALT successfully treated by radiotherapy alone.

A Case of Video-Assisted Thoracoscopic Pneumonectomy for Unilateral Diffuse Pulmonary Arteriovenous Malformation / 결핵및호흡기질환

Pulmonary arteriovenous malformations (PAVMs) are abnormal direct communications between the pulmonary arteries and veins. PAVMs may occur as either an isolated abnormality or in association with hereditary hemorrhagic telangiectasia, also called Osler-Weber-Rendu disease. The topic of PAVM has recently been extensively reviewed, but little is known about the clinical characteristics and course of patients having a diffuse pattern of the disease. Herein, is reported a case of unilateral diffuse PAVM in an 18 year old female patient, who underwent a right pneumonectomy, under a video-assisted thoracic surgery (VATS) approach, as the diffuse small pulmonary arteriovenous malformation involved the whole right lung.

Long-term Survival after Surgical Resection for Liver Metastasis from Gastric Cancer: Two Case Reports / Journal of the Korean Cancer Association, 대한암학회지

Surgical resection of colorectal cancer metastasis to the liver results in a 5-year survival rate of around 40%. Liver metastasis from other cancers such as neuroendocrine carcinoma and genitourinary tumors are also treated effectively with combined liver resection. However, hepatic metastasectomy for liver tumor from gastric cancer hasn't been considered as a standard treatment, and the benefit for this treatment has not been established. We report here on two cases of gastrectomy and combined liver resection for synchronous liver metastasis without any evidence of other metastatic lesions, and these two patients have survived for more than 7 years without evidence of disease recurrence. In conclusion, for patients with hepatic metastasis from gastric cancer, combined surgical resection of the liver metastasis should be considered as a treatment option when metastasis to other sites can be excluded.

A Case of Analgesic Nephropathy Complicated by Transitional Cell Carcinoma of the Ureter / 대한신장학회잡지

Following a report by Hultengren et al. (Acta Chir Scand, 1965), it has been suggested that analgesic abuse predisposes to urothelial neoplasia. Urinary tract malignancy is combined in 8-10% of patients with analgesic nephropathy. Microscopic or gross hematuria can be the first sign leading to the diagnosis of uroepithelial malignanacy in analgesic abusers. Since uroepithelial malignancies found in analgesic abusers tend to be multiple and have a worse prognosis, continued monitoring is essential, and new hematuria should be evaluated with urinary cytology, and cystoscopy with reterograde pyelography. Phenacetin found to be the chief cause of malignancies in analgesic abusers, it has been anticipated to be a human carcinogen and was banned as an OTC drug since 1987. But still there remains a debate whether acetaminophen and other compound analgesic components are carcinogenic. We report the case of a 58-year-old man with a history of analgesic abuse who was diagnosed with transitional cell carcinoma combined with analgesic nephropathy. We also review the literature.
