Abstract

Abstract : Background: Primary cutaneous mucinous carcinoma (PCMC) is a rare epithelial tumor with unclear histogenesis. Methods: We evaluated the immunohistochemical expression of the estrogen receptor (ER), progesterone receptor (PR), and androgen receptor (AR) in six cases of PCMC. The immunoreactivity of adipophilin and gross cystic disease fluid protein (GCDFP)‐15 was investigated to determine the origin of the tumor. Results: The study included five males and one female aged 50 to 69 years who presented with a cutaneous mass in the face. Immunoreactivity for ER, PR, and AR was observed in all cases, and all cases were negative for adipophilin but positive for GCDFP‐15. Conclusions: This report is the first to show AR expression in PCMC. All of followed cases manifested indolent clinical course, and the prognostic significance of hormone receptors in PCMC remains unclear. The negative immunoreactivity of PCMC for adipophilin and positivity for GCDFP‐15 suggests a more likely relationship to apocrine than to sebaceous glands.
