Abstract

BACKGROUND 

Mucoepidermoid carcinoma is a relatively common neoplasm of the major and minor salivary glands comprising 10–30% of primary carcinomas. They may involve the skin through direct extension, metastases, and rarely, as a primary focus (adenosquamous carcinoma).

OBJECTIVE 

To discuss through case reports, the nomenclature, histology, clinical course, and treatment of mucoepidermoid/adenosquamous carcinoma.

METHODS 

We present a case of mucoepidermoid carcinoma primary to an upper eyelid accessory lacrimal gland with direct cutaneous extension and a case of primary cutaneous adenosquamous carcinoma of the scalp.

RESULTS 

An eyelid neoplasm of lacrimal origin was initially treated with Mohs micrographic surgery (MMS), requiring an orbital exenteration to achieve a tumorfree plane. In the second case, a primary scalp lesion was cleared with MMS. Neither patient has had local recurrence or metastases.

CONCLUSION 

Correct diagnosis is crucial to pursuing adequate treatment for this aggressive neoplasm. We support the use of MMS to achieve local control.
