Dermoscopy revealed a well-defined, erythematous-pink tumor (Fig. 2A) with prominent, more or less evenly distributed blood vessels, with characteristic cherry blossom images mostly at the periphery of the tumor (Fig. 2B), and pale pink structureless areas (Fig. 2A). With a suspected diagnosis of eccrine poroma, the lesion was excised and the histological findings confirmed the diagnosis. Eccri...

BACKGROUND Protease-activated receptor 2 (PAR-2) participates in various biological activities, including the regulation of epidermal barrier homeostasis, inflammation, pain perception, and melanosome transfer in the skin. OBJECTIVE To evaluate the basic physiological role of PAR-2 in skin. METHODS We investigated PAR-2 expression in human epidermis, skin tumors, and cultured epidermal cell...

The coiled duct of the eccrine sweat glands consists of two or three layers of epithelial cells concentrically a r ranged around the lumen (Fig. 1). The superficial cells have a fibrous luminal border ; the peripheral cells, usually contain moderate amounts of glycogen and rest on a poorly developed basement membrane . Numerous blood vessels and unmyel ina ted nerves adhere to the coiled duct. ...

The electron microscopy of human eccrine sweat glands has been studied before and after stimulation by pilocarpine iontophoresis. The identity of the dark and clear cells in the secretory segment as defined by Montagna et al. (23) was determined by studying serial sections, thin for electron microscopy and thick for light microscopy. Cells with numerous apical secretory vacuoles are termed muco...

The eccrine sweat glands of the cat foot and toe pads have been studied by light and electron microscopy before and after stimulation with mecholyl. The ultrastructure of these glands in the cat is found to be entirely comparable to that in the human (13). The ultrastructure and staining properties of the secretory segment of the two species are identical. The ductal part of the feline gland is...
