ABSTRACT
Leiomyosarcoma is a rare tumor of the liver. It usually arises from many other organs including uterus, gastrointestinal tract, retroperitoneum, and soft tissues. Primary hepatic leiomyosarcoma progresses very slowly and is not associated with chronic liver disease. When the tumor is detected early enough to be treated by operation, the prognosis is favorable. While several cases of primary hepatic leiomyosarcoma have been reported in Korea, there was no case associated with acute bleeding. We report a 80-year old male patient with huge primary hepatic leiomyosarcoma, who presented with acute bleeding and IVC obstruction. The patient was treated by embolization and IVC stenting.

Chronic diarrhea is one of the most frequent gastro-intestinal manifestations in acquired immunodeficiency syndrome (AIDS). Protozoa and nontuberculous mycobacteria (NTM) are opportunistic pathogens that can easily infect these patients. Among the NTM, Mycobacterium avium complex (MAC) is the most frequently observed pathogen in HIV-infected patients. However, NTMs other than MAC have not been reported as a gastrointestinal pathogen as yet. We present a case of chronic diarrhea in an AIDS patient in whom Mycobacterium ulcerans and cryptosporidium co-infection is evidenced from colonic tissue.

Tuberculous colitis, an important extra-pulmonary tuberculosis, is still prevalent in the developing countries and has been resurging in the Western world. The duration and dose of anti-tuberculous therapy have not yet been clarified in the tuberculous colitis. We experienced a case of tuberculous colitis, which relapsed after 9 months of therapy. A 28-year-old man presented with hematochezia and was diagnosed as tuberculous colitis on the basis of colonoscopic findings. He was treated with anti-tuberculous agents for 9 months successfully. Three months later, however, he complained of hematochezia again, suggesting the relapse of tuberculous colitis. He had taken anti-tuberculous therapy for another 15 months and showed no evidence of relapse. Although anti-tuberculous therapy is efficient for tuberculous colitis, rare cases of reactivation should be reminded.
