Microcystic adnexal carcinoma (MAC) is an uncommon, locally aggressive cutaneous neoplasm that usually presents as a slow-growing, asymptomatic lesion on the head or neck. Microcystic adnexal carcinoma frequently is misdiagnosed due to its histologic appearance on superficial biopsy specimens mimicking other follicular neoplasms. Herein, we highlight a case in which a slow-growing lesion was initially diagnosed as a trichoadenoma following superficial biopsy; however, after surgical excision the pathology revealed a locally aggressive MAC.

Background: Extramammary Paget's disease is a rare neoplasm primarily affecting apocrine gland bearing skin. Although primarily affecting the anogenital area, the tumor also rarely appears in nonapocrine bearing skin and is referred as ectopic extramammary Paget's disease., Objective: To our knowledge, we present only the second case of ectopic extramammary Paget's disease appearing on the face., Methods: Using Mohs micrographic surgery, a rare case of ectopic extramammary Paget's disease on the face was treated in three stages., Results: At 5 months there was no evidence of recurrence., Conclusion: Ectopic extramammary Paget's disease is a rare disease that can be effectively treated with Mohs micrographic surgery.
