Before 2003, lymphogranuloma venereum (LGV) was rare in developed nations. Several large clusters of LGV in men who have sex with men have been reported across Europe and in the United States of America (USA) since 2003. LGV is caused by L1, L2 and L3 serovars of Chlamydia trachomatis and is a sexually transmitted infection. LGV causes genital ulcers, infected inguinal lymph nodes (buboes) and proctitis/proctocolitis. Treatment with a three-week course of doxycycline prevents rectal strictures, bowel obstruction, bowel perforation and possibly death. Clinicians seeing men who have sex with men with inguinal lymphadenopathy and bowel symptoms should be aware of this current epidemic.

Epidemic Kaposi's sarcoma remains the most common cancer in patients with human immunodeficiency virus and is associated with significant morbidity and mortality in AIDS patients. Primary visceral Kaposi's sarcoma (Kaposi's sarcoma without cutaneous lesions) presenting with lower gastrointestinal bleeding (LGIB) has rarely been reported. Though Kaposi's sarcoma can occur anywhere in gastrointestinal tract, gastrointestinal symptoms are often non-specific such as chronic blood loss anaemia, vomiting, diarrhoea, intestinal obstruction. In these patients, severe gastrointestinal bleeding requiring repeated blood transfusions is extremely rare. Clinicians should be aware of gastrointestinal tract Kaposi's sarcoma since visceral Kaposi's sarcoma can present in the absence of cutaneous involvement. Endoscopy with biopsy is useful in the diagnosis for severe LGIB in patients with AIDS. Furthermore, gastrointestinal Kaposi's sarcoma should be considered in the differential diagnosis of GI bleeding. We report a case of primary colonic KS who presented with recurrent GI bleeding which was eventually diagnosed by sigmoidoscopy and confirmed pathologically.
