Summary

Kaposi’s sarcoma is a fatal disease that typically presents with cutaneous manifestations in immunocompromised individuals. There are a small number of documented cases where patients diagnosed with this disease present without cutaneous lesions. We present a 35-year-old man with recurrent rectal abscesses and fistula-in-ano, which required multiple drainage procedures. Further investigation revealed a diagnosis of HIV-AIDS, and biopsy of a rectal mass confirmed the diagnosis of visceral Kaposi’s sarcoma, despite the absence of cutaneous involvement. Workup revealed hepatic metastasis and a second pulmonary primary malignancy. The patient denied chemotherapy or further intervention and was subsequently lost to follow-up. Prompt diagnosis of Kaposi’s sarcoma and initiation of treatment is vital to decrease disease progression. A high index of suspicion should be present in immunocompromised patients, and clinicians must recognise atypical presentations in order to improve long-term survival.
