Primary auricular melanoma is rarely reported. Approximately, it accounts for 1% to 4% of all cutaneous melanoma. Early literature suggested that melanoma of the ear is more aggressive than other melanomas, with a propensity for spreading to both regional lymph nodes and distant sites. Here, we present a case of cytological pleural metastasis from auricular melanoma in a 43-year-old woman. Immunohistochemical staining showed that the tumors cells were positive for S-100 protein and Melan-A.

Abstract

Primary auricular melanoma is rarely reported. Approximately, it accounts for 1% to 4% of all cutaneous melanoma. Early literature suggested that melanoma of the ear is more aggressive than other melanomas, with a propensity for spreading to both regional lymph nodes and distant sites. Here, we present a case of cytological pleural metastasis from auricular melanoma in a 43-year-old woman. Immunohistochemical staining showed that the tumors cells were positive for S-100 protein and Melan-A. The mutation of the v-raf murine sarcoma viral oncogene homolog B (BRAF)(V600E) was demonstrated on Sanger sequencing. To our knowledge, this is the first report describing the cytomorphology of metastatic auricular melanoma in pleural effusion.
