Purpose: Mucinous eccrine carcinoma of the skin is rare skin adnexal malignant tumor, which most commonly occurs in the head and neck regions. This tumor, although rarely metastatic, has a high incidence of local recurrence. We report a case of mucinous eccrine carcinoma developed on the Lt. cheek which was treated by Mohs surgery. Methods: The patient was a 53-year-old man who showed a palpable skin-colored $1.5{\times}1.5cm$ sized mass on Lt. cheek. We treated it by wide excision, but it recurred several times on the same region. So we finally did the Mohs surgery and full thickness skin graft. Results: The histologic characteristics are large mucinous pools with fibrous septae and clusters of tumor cells. Special stains showed that the mucin was positive reactivity on Periodic acid Schiff. Also the immunocytochemical studies showed a positive reactivity to carcinoembryonic antigen, S-100 protein, cytokeratin-7. Therefore pathologist reported it as a mucinous eccrine carcinoma. Conclusion: Authors experienced a rare case of primary mucinous eccrine carcinoma on Lt. cheek which had recurred several times. Because of the high local recurrence rate, we did the Mohs surgery and got an good result. Therefore the early Mohs surgery would be a good choice to primary mucinous eccrine carcinoma.

Dermoid cyst is a developmental cyst that is lined by epidermis-like epithelium and contains dermal adnexal structures in the cyst wall. Dermoid cyst most occur in the eye brow although occasionally develop in other locations such as midline of the floor of the mouth, tongue, lip and buccal mucosa. The lesion is slow growing and painless without lympadenopathy. The contents of the dermoid cyst can be caseous or sebaceous. The size can vary from a few millimeters to 12cm in diameter. Histologically, dermoid cyst is lined by epidermis and adnexaes such as sweat gland, sebaceous glands and hair follicles are present in the cyst wall. The 2-year-old female of this case visited Department of Pediatric Dentistry, College of Dentistry, Yonsei University with a chief complaint of the emergence of mass on her upper lip. An excisional biopsy was carried out for a histological examination and sebaceous gland was observed in the cyst wall. The lesion was diagnosed as dermoid cyst. Dermoid cyst does not recur if complete excision is accomplished.
