Abstract
Background: Kaposi sarcomais a low-grade malignant vascular lesion, which has different histological variants. Pyogenic granuloma-like Kaposi sarcoma is an unusual type of this tumor, which presents as anexophytic small nodule surrounded by an epidermal collaret mimicking pyogenic granuloma yet it has immunohistopathologic features of Kaposi sarcoma. Case Presentation: A 57-year old male with 2 exophytic lesions on the left hand and left foot for 3 months was presented to our center. Both lesions were excised and diagnosis of Kaposi sarcoma was confirmed by histopathology and immunohistochemistry. Human herpesvirus 8 DNA was detected by the polymerase chain reaction in the lesions. Conclusions: Immunostaining methods should be considered in pyogenic granuloma-like lesions with unusual presentation.
