Unusual presentation of Kaposi sarcoma in an HIV-negative woman

摘要

Kaposi sarcoma typically presents as violaceous macules and papules in immunocompromised, specifically HIV-positive, patients. Its distinct clinical features often facilitate rapid diagnosis. In this article, we report a case of Kaposi sarcoma presenting as a concerning yet nondescript lesion in an HIV-negative woman. Although Kaposi sarcoma is frequently part of the differential diagnosis for skin lesions affecting HIV-positive patients, it is less frequently considered in HIV-negative individuals. Additionally, this case differs from the classic clinical presentation of Kaposi sarcoma by resembling a squamous cell carcinoma or superficial basal cell carcinoma. Therefore, it illustrates the importance of suspicious lesion biopsies to ensure accurate diagnosis and appropriate treatment.
