A Case of Clear Cell Acanthoma / 대한피부과학회지

ABSTRACT

We report a case of clear cell acanthoma occurred in a 61 year old man. He developed a brownish bean sized nodule on the left chest 3 years ago. The skin lesion has slowly increased in size without any subjective symptoms. Histopathologic examination revealed proliferation of clear cells within a sharply demarcated area of the epidermis. The presence of numerous neutrophils throughout the epidermis were also noted.
