Periodic Acid-Schiff Positive Material Accumulating Within the Lumen of Eccrine Sweat Glands1

Eccrine sweat gland carcinoma.

The differential diagnosis among the most frequent skin tumors, base-cell carcinoma and squamous-cell carcinoma, and the rare types, the sweat gland carcinomas, is fundamental for the early diagnosis and prognosis of a patient. These are classified as eccrine and apocrine, and the eccrine is the most common type. The eccrine sweat glands are most abundant in the palms of the hands and the feet ...

Characterization of Periodic Acid-Schiff-Positive Granular Deposits in the Hippocampus of SJL/J Mice.

Periodic acid-Schiff (PAS)-positive granular deposits in the hippocampus have been reported previously in certain inbred mouse strains such as C57BL/6 and the senescent-accelerated mouse prone-8. Here, we report for the first time that similar PAS-positive granules age dependently occur in SJL/J mice, a mouse strain, for instance, used for central nervous system disease research. Moreover, simi...

Sweat induction from an isolated eccrine sweat gland.

SAW, KENZO. Sweat induction from an isolated eccrine sweat gland. Am. J. Physiol. 225(5) : 1147-l 152. 1973.-A method has been developed for in vitro induction of sweating from an isolated monkey-palm eccrine sweat gland. The validity of the new methodology is shown in the following results. MecholyLinduced sweating was completely inhibited by atropine and by cooling the incubation medium to 4 ...

Prognostic significance of periodic acid-Schiff-positive patterns in primary cutaneous melanoma.

The patterns of periodic acid-Schiff (PAS) staining of extracellular matrix in histological sections of certain melanomas may be predictive of outcome. Recent in vitro and molecular genetic data suggest that the appearance of these patterns in both uveal and cutaneous melanoma is a function of aggressive tumor cells. We studied 96 patients with primary cutaneous melanomas treated at the Univers...
