Unusual presentation of Kaposi sarcoma in an HIV-negative woman

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

A case report of bosutinib-induced interstitial granulomatous drug reaction in a patient with chronic myelogenous leukemia: a case report

Bosutinib is a BCR-ABL tyrosine kinase inhibitor approved for the treatment of Philadelphia chromosome–positive chronic myelogenous leukemia. We report a case of bosutinib-induced interstitial granulomatous drug reaction in a 50-year-old Caucasian female with chronic myelogenous leukemia. Histologic analysis of a punch biopsy showed diffuse interstitial granulomatous infiltrates consisting of histiocytes amid thickened collagen accompanied by eosinophils. Her lesions improved with clobetasol 0.05% cream. No cases describing BCR-ABL tyrosine kinase inhibitor–associated interstitial granulomatous drug reaction were found in a search of the literature. It is important for physicians to be aware of the risk of interstitial granulomatous drug reaction associated with bosutinib treatment
