Primary gastrointestinal lymphomas are quite rare with the stomach and small bowel being the most frequent site. Colon involvement is observed in only 10~20% of all gastrointestinal lymphomas. A colonic lymphoma presents with non-specific abdominal pain, weight loss, a change in bowel habits, bleeding, intestinal obstruction, intussusception and a palpable mass. A colonic lymphoma can be indicated using a barium enema, abdominal CT and colonoscopy. The correct diagnosis is obtained by a colonoscopic biopsy. We report a case of primary colonic non-Hodgkin's lymphoma with peritoneal carcinomatosis and a right pleural effusion.

BACKGROUND: The Fujiwara-kyo Osteoporosis Risk in Men (FORMEN) study was launched to investigate risk factors for osteoporotic fractures, interactions of osteoporosis with other non-communicable chronic diseases, and effects of fracture on QOL and mortality. METHODS: FORMEN baseline study participants (in 2007 and 2008) included 2012 community-dwelling men (aged 65-93 years) in Nara prefecture, Japan. Clinical follow-up surveys were conducted 5 and 10 years after the baseline survey, and 1539 and 906 men completed them, respectively. Supplemental mail, telephone, and visit surveys were conducted with non-participants to obtain outcome information. Survival and fracture outcomes were determined for 2006 men, with 566 deaths identified and 1233 men remaining in the cohort at 10-year follow-up. COMMENTS The baseline survey covered a wide range of bone health-related indices including bone mineral density, trabecular microarchitecture assessment, vertebral imaging for detecting vertebral fractures, and biochemical markers of bone turnover, as well as comprehensive geriatric assessment items. Follow-up surveys were conducted to obtain outcomes including osteoporotic fracture, cardiovascular diseases, initiation of long-term care, and mortality.
