GI tract involvement occurs in up to 40% of patients. However, most cases of KS of the GI tract are asymptomatic. AIDS-related KS most frequently manifests with skin disease ( Figure 56-5 ). However, cutaneous manifestation may be absent in visceral KS. Symptoms of GI KS are dyspepsia, diarrhea, GI bleeding, perforation, and ileus resulting from tumor obstruction
