Myoepithelial Carcinoma Mimicking Basal Cell Carcinoma: A Case Report.

We present the case of an 81-year-old male with a two-month history of a rapidly growing red nodule measuring 6 mm x 10 mm on his left malar cheek. Histological examination confirmed the diagnosis of myoepithelial carcinoma. The nodule was fully excised with a 3.8 mm radial margin and a close deep margin of 0.95 mm. This was followed by a wide local excision with a 5 mm margin, including subcutaneous fat up to the muscles of facial expression, and closed with a lateral cheek advancement flap per the specialist skin multidisciplinary team (SSMDT) recommendation. Postoperatively, the patient has been followed up as per the high-risk squamous cell carcinoma protocol, including four-monthly clinic reviews in the first year and six-monthly reviews in the second year. This case highlights the importance of raising awareness around cutaneous myoepithelial carcinoma's rare presentation and diagnostic challenges, and the importance of multidisciplinary management with long-term follow-up.
