A Case of Nodular Melanoma Mimicking Seborrheic Keratosis / 대한피부과학회지

ABSTRACT

The diagnosis of nodular melanomas can be sometimes difficult, in case they lack the conventional clinical features of melanoma. Herein, we report a case of malignant melanoma mimicking seborrheic keratosis. The clinical diagnosis was seborrheic keratosis. The histopathologic examination revealed nodular melanoma with features of reticulated form of epidermal hyperplasia, pseudohorn cysts, and irregular hyperkeratosis and acanthosis. The tumor was excised with 2.5 cm margins and no remnant of tumor cells was found in the microscopic examination.
