Abstract:
Endocrine mucin-producing sweat gland carcinoma (EMPSGC) has recently been recognised as a low-grade carcinoma that almost always occurs on the eyelid. This carcinoma is very rare, with only 20 cases (including the present one) having been reported in the literature. EMPSGC is frequently found in association with invasive mucinous carcinoma. While EMPSGC treatments consist of a complete surgical removal, there has been no consensus regarding the surgical margin. Therefore, reports on surgical management of EMPSGC may potentially provide important therapeutic information. Here, we present a case of a 74-year-old man with EMPSGC of the eyelid that repeatedly recurred despite surgical treatments at another institution. After referral to our department, the patient underwent tumour excision. However, the specimen revealed a positive surgical margin and thus, he subsequently underwent a wider excision. There has been no sign of tumour recurrence or metastasis 6 months after his last operation. This article reviews the current literature and discusses the surgical management of EMPSGC.

Exocrine Glands: Methods of Secretion
Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine glands...

Sweat glands are classified as merocrine glands; that is, the secretions are excreted by exocytosis through a duct without affecting the cells of the gland. There...

Exocrine Glands: Types of Secretions
Serous glands produce watery secretions rich in digestive enzymes and proteins. The constituent cells of the serous gland have centrally located nuclei and eosinophilic secretory granules in the cytoplasm. The parotid gland is an example of a serous gland. It secretes saliva, which contains enzymes, such as lipases and...
