Kaposi's sarcoma in women: A clinicopathologic study

Area of Science:

• Oncology
• Dermatology
• Virology

Background:

• Kaposi's sarcoma (KS) has diverse epidemiologic subsets (sporadic, endemic, epidemic, iatrogenic) linked to human herpesvirus 8 (HHV8).
• Distinct clinical features characterize each KS subset, with men predominantly affected across all groups.
• Understanding KS in women requires analyzing specific clinical and histopathologic presentations.

Purpose of the Study:

• To investigate the clinical and histopathologic features of Kaposi's sarcoma (KS) in women.
• To identify any specific associations within this patient population.
• To characterize the epidemiologic subset distribution of KS in women.

Main Methods:

• Retrospective review of 250 histologically confirmed cutaneous Kaposi's sarcoma (KS) cases in women.
• Data collected between 1975 and 1993.
• Analysis of clinical presentation, histopathology, and patient demographics.

Main Results:

• 80% of women diagnosed with KS were over 60 years old.
• Of patients under 60, 28 were from endemic KS regions; most HIV+ patients were also from endemic areas.
• The majority of lesions were plaque or tumor stage; angiosarcoma-like patterns correlated with aggressive subsets, but high mitotic rates did not.

Conclusions:

• Kaposi's sarcoma in women is predominantly diagnosed in plaque or tumor stages.
• Most women in this cohort were classified within the sporadic KS epidemiologic subset.
• Clinical and histopathologic features provide insights into KS behavior in women.
