Summary
Classic Kaposi's sarcoma, typically affecting older men, presented unusually in two younger, heterosexual, HIV-negative males. The aggressive, late-stage disease showed rare clinical features and responded to radiation, interferon, and chemotherapy.
Area of Science:
- Oncology
- Dermatology
- Immunology
Background:
- Classic Kaposi's sarcoma (KS) predominantly affects elderly men of Mediterranean descent, typically presenting as skin lesions on the lower extremities.
- This presentation challenges the typical demographic and clinical profile of classic Kaposi's sarcoma.
Observation:
- Two heterosexual, HIV-negative males of Greek origin from Albania developed classic Kaposi's sarcoma in their third decade.
- After ten years, the disease progressed aggressively with atypical features, including exophytic tumors, widespread lesions (hands, legs, face, trunk, palate), and significant leg edema.
- One patient also exhibited bubonic lymphadenopathy, with both cases showing normal CD4 counts and positive HLA-DR5.
Findings:
- The patients received treatment including radiation therapy, subcutaneous interferon (alpha-2b), and combination chemotherapy (ABV).
- Both patients achieved partial remission with significant clinical improvement and were maintained on interferon therapy at 1- and 2-year follow-ups.
Implications:
- This case report expands the understanding of classic Kaposi's sarcoma presentation, highlighting potential for atypical and aggressive disease in younger, HIV-negative individuals.
- It underscores the importance of considering unusual presentations and the efficacy of multimodal treatment approaches, including interferon, in managing advanced classic KS.
