BACKGROUND: Microcystic adnexal carcinoma is an uncommon malignancy of the skin with a propensity for local aggressive growth and high rates of recurrence. To date, this neoplasm has been described mainly in the Caucasian population. We describe here the first reported case in a black patient. OBJECTIVE: To discuss the successful identification and management of this aggressive neoplasm in the non-Caucasian population. METHODS: Mohs micrographic surgery was performed on this tumor. RESULTS: The tumor was successfully excised without evidence of recurrence at 6 months. CONCLUSIONS: We present the first reported case of microcystic adnexal carcinoma in a black patient. This tumor was identified in its early stages and removed by Mohs micrographic surgery without sequelae.
Mohs' surgery often requires multiple dressing changes in a single day. The innovative dressing method described here provides a reproducible, visually acceptable dressing with minimal damage to the patient's uninvolved skin. It also allows speedy removal and a smooth flow of events for the health care team.
Microcystic adnexal carcinoma (MAC) is a recently described malignant neoplasm of the adnexal structures of skin that shows a marked propensity for early infiltrative and locally aggressive growth. Its banal clinical appearance may lead to a delay in diagnosing the tumor by biopsy, and its multifaceted histologic features may lead to an incorrect tissue diagnosis. Confusion with benign tumors and less aggressive malignancies can lead to inadequate initial treatment and extensive recurrences. We describe three cases of microcystic adnexal carcinoma and review the clinical and histologic features, treatment, and prognosis of this neoplasm.
Chromomycosis and protothecosis are both rare cutaneous infections. We report a case in which protothecosis mimicked a relapse of chromomycosis both clinically and on special stains. The chromomycosis responded to local excision and ketoconazole therapy. The protothecosis failed to respond to ketoconazole but resolved with combined amphotericin B and tetracycline hydrochloride therapy.
