Apocrine hidrocystomas (cystadenomas) are cystic cutaneous neoplasms derived from apocrine sweat glands (1, 2), and they most often present in adults as solitary (rarely multiple) lesions involving the head, eyelids and neck (3). They are also reported infrequently in the apocrine gland bearing areas like axillae, areola of the nipple, periumbilical, anal, and genital areas (3, 4). We present a...

The sweat eccrine and apocrine glands of human skin secrete many functionally significant substances, including hydrolytic enzymes, onto its surface through the mechanisms secretion, excretion recruitment. Shown is their recreational origin as a secretory product digestive glands—pepsinogen by stomach glands, α-amylase—by pancreas. Hydrolases in epidermal barrier provide hydrolysis proteins, ca...

Two types of glands are found in the outer third of the human earcanal: sebaceous glands that produce sebum and modified apocrine glands that produce apocrine sweat. Together, these substances make up cerumen, which serves to clean, lubricate, and, to some extent, protect the earcanal from bacteria and fungus. Excessive/impacted cerumen can cause tinnitus, vertigo, itching, pain, external otiti...

Preliminary to a study of benign appendageal tumors of the skin, the results of which will be published separately, the following study of normal apocrine and eccrine glands was undertaken. The use of the periodic acid-Schiff (PAS) and Alcian Blue (AB) stains separately on tissue sections and the clarification of the two color reactions of the PAS stain by Alcian Blue (1) has lead to a better h...

INTRODUCTION Tumour and tumour-like lesions of the eyelids are more common in dogs than cats. In the feline, malignant tumours outnumber benign types, with eyelid neoplasms essentially arising from the haired skin. Based on 1 study, squamous cell carcinomas, fibrosarcomas and adenocarcinomas constitute 73.5 % of all feline eyelid tumours. Apocrine hidrocystomas in cats are rare, solitary and mo...

A 43-year-old Chinese man presented with generalized hypohidrosis, which he had had since birth, without obvious abnormalities of other skin appendages except a sparse beard and axillary hairs. The sweat test revealed localized sweating on the face, axillae and palms. Histopathologic examination showed that the sweat glands were absent in the forearm and thigh, but some eccrine and apocrine swe...

Tumours of cutaneous sweat glands are uncommon, with a wide histological spectrum, complex classification and many different terms often used to describe the same tumour. Furthermore, many eccrine/apocrine lesions coexist within hamartomas or within lesions with composite/mixed differentiation. In addition to the eccrine and apocrine glands, two other skin sweat glands have recently been descri...

Apocrine chromhidrosis is a very rare, idiopathic disorder of the sweat glands characterized by the secretion of colored sweat. Because hormonal induction increases sweating, the symptoms of apocrine chromhidrosis usually begin after puberty. Although treatment may not be necessary in some cases, capsaicin cream and 20% aluminum chloride hexahydrate solution have been successfully used to treat...

OBJECTIVES To determine the cellular localization in male and female axillary tissue for apocrine secretion odor-binding proteins 1 (ASOB1) and 2 (ASOB2) and the electrophoretic pattern of female apocrine proteins and to begin characterization of the ASOB1 protein. DESIGN Immunohistochemical techniques were used with biopsy samples from axillary tissue of male and female subjects. Immunologic...

Cutaneous sweat gland carcinoma is an extremely rare malignant skin cancer which may arise from the apocrine or eccrine types of glands. It has a high mitotic index and potential [1] usually occurs in elderly people, without any gender predilection.
