Abstract: he clinical manifestations, histopathological and immunohistochemical features, treatment and prognosis were retrospectively reviewed in 8 patients with clear cell hidradenoma. Of eight patients, there were 3 males and 5 females. The lesions were mainly on head and face. The common lesions were skin-colored or light red nodules, with no obvious subjective symptoms in all cases. Biopsy revealed that the tumor was composed of two types of cells: larger clear cells and smaller basophilic polyhedral cells. Immunohistochemical staining revealed that the tumor cells were positive for epithelial markers. The lesions were removed in all patients.

Key words: clear cell hidradenoma, clinical manifestations, pathology, immunohistochemistry
