Classic Kaposi Sarcoma (KS) may affect mucosa, especially oral cavity and any part of the gastrointestinal tract. It has been reported in 10% of patients with classic KS. We report a 35-year old male patient with primary classic KS in jejunum that presented with bowel obstruction. Primary presentation of classic KS in the gastrointestinal tract is very infrequent. There have only been 9 cases of primary KS in colon reported in literature, and none in jejunum. This is the first primary classic KS in jejunum described in our country. Likewise, we recommend that certain patients with classic KS should have an upper gastrointestinal endoscopy to determine compromise. The few gastrointestinal KS reported cases may be due to subdiagnosis.
