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.

Mucinous Eccrine carcinoma (MEC) is a rare malignant tumor related to the eccrine sweat gland and is commonly located on the face, especially around the eyelids and scalp. Most of these tumors are diagnosed at age 40's to 60's and exhibit a wide variety of patterns in addition to the general appearance previously reported. MEC is difficult to diagnose clinically, but can be diagnosed by accompanying biopsy. We present the case of a 75-year-old man who complained of a gradually growing Left lower lid tumor of duration one year. Initially, the tumor was mistaken for an epidermal cyst and treated by surgical resection. However, biopsy findings resulted in a diagnosis of Mucinous Eccrine carcinoma. Therefore, we performed wide excision and flap reconstruction surgery. In a one year follow-up examination, the patient achieved successful functional and aesthetic results without regional or distant metastasis and recurrence.

Primary cutaneous mucinous carcinoma (PCMC) is a rare malignant tumor of eccrine origin. Clinically, the carcinoma presents as a solitary, slow growing, and painless nodule. For this reason, this tumor is often considered to be a benign mass in the preoperative setting. The lesion is, however, malignant in nature and has a tendency for local recurrence and infrequent metastasis. Wide local excision is the treatment of choice. However, few reports exist with information regarding surgical margins and clinical outcomes. Herein, we report a case of PCMC excised with a narrow surgical margin and review the relevant literature. A 49-year-old man presented with a small cutaneous nodule of the right cheek. The mass was excised without any margin, but pathologic examination revealed histology of mucinous carcinoma. Because of this, the operative site was re-excised with a 5-mm margin, and the wound was closed using a V-Y advancement flap. Systemic work-up did not reveal other potential metastatic primary, for a final diagnosis of PCMC. We report this case of PCMC, treated with relatively narrow margin in a patient with good prognostic factors.

Primary cutaneous mucinous carcinoma (PCMC) is a rare low-grade malignant neoplasm derived from the eccrine glands. PCMC most commonly arises in the head and neck, with the eyelid being the most common site of origin. This case report describes a 51-year-old male with a painless, pigmented superficial nodular lesion over his right lower eyelid. The lesion was considered to be benign, and the initial treatment was simple excision with a 3-mm margin. However, histologic examination revealed the diagnosis of PCMC, and the patient underwent re-excision of the tumor site with an additional 3-mm margin from the initial scar. Histologic study of this second margin was free of any malignant cells. The patient experienced no postoperative complication or recurrence after 2 years. In our case, the skin lesion had benign morphologic findings and was strongly suspected to be a benign mass. Physicians should be aware of this tumor and be able to differentiate it from benign cystic or solid eyelid lesions.
