Abstract
INTRODUCTION
Microcystic adnexal carcinoma (MAC) is a rare malignant cutaneous neoplasm presenting as a slow-growing, indurated nodule, papule or plaque. Clinically, the lesion can blend into the surrounding skin, obscuring borders and consequently delaying diagnosis histologically. Surgical and histologic techniques that emphasize examination of all margins may optimize management through early diagnosis and prevention of recurrences.
OBJECTIVE
This review aims to assess the current surgical and histology techniques that result in lower rates of tumor recurrence and, consequently, better clinical outcomes.
METHODS
A literature search of the PubMed database was conducted to identify studies examining wide local excision (WLE), Mohs micrographic surgery (MMS), radiotherapy (RT) and chemotherapy in the treatment of MAC.
RESULTS
WLE had a high likelihood of positive margins and local recurrence. MMS was found to have the lowest recurrence rates. Definitive RT could be considered for elderly patients or those who are poor surgical candidates, as large surgical defects may be required to obtain free margins with either WLE or MMS. Chemotherapy was found to be ineffective.
CONCLUSION
Complete margin evaluation with MMS permits complete tumor removal with subsequently low recurrence rate.
