Transmutation of Sweat Glands - Eccrine Porocarcinoma

Secretion of eccrine sweat glands during exercise.

Metabolic studies of isolated human eccrine sweat glands.

This paper describes a method for isolating and studying the metabolism of human eccrine sweat glands. (a) Electron microscopy of glands which had been isolated and then incubated for an hour revealed no apparent alteration in morphology. (b) Known variation in gland size (male > female > children) was reflected in the relative rates of lactate production. (c) Lactate production was approximate...

The Ultrastructure and Histophysiology of Human Eccrine Sweat Glands

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...

Electron microscopic study on human eccrine sweat glands.

Electron microscope observations on eccrine sweat glands have been carried out by many workers, namely on human eccrine swear glands by HIBBS (1958), IIJIMA (1959), CHRALES (1960), KUROSUMI et al. (1960), and MUNGER (1961) and on those of animals by KITAMURA (1958), MUNGER et al. (1961), ELLIS et al. (1961), MATSUZAWA et al. (1963), KUROSUMI et al. (1964) and TERZAKIS (1964). Already by means o...

[Eccrine porocarcinoma of the scalp].

OBJECTIVE Eccrine porocarcinoma is a rare malignant tumor of eccrine sweat glands. It may arise de novo, but it usually develops in pre-existing eccrine poroma. Here we report a case of eccrine porocarcinoma in the grafted area on the scalp of a male patient who had recurrent basal cell carcinoma of the scalp, with clinical, histopathological and, immunohistochemical features. CASE We report ...
