acrospiroma/peroxidase

OBJECTIVE To make a quantitative evaluation by image analysis of oestrogen receptors, progesterone receptors, and androgen receptors in papillary hidradenomas and anogenital sweat glands. METHODS 20 papillary hidradenomas and the anogenital sweat glands detected in surgical specimens selected from

Although myoepithelial cells are detectable in many benign sweat gland tumours, little is known about their role in sweat gland carcinomas. To specifically demonstrate myoepithelial cells, paraffin sections from 46 sweat gland carcinomas were stained, using a standard avidin-biotin-peroxidase

Phytohemagglutinin (PHA)-binding sites were histochemically investigated in normal adult skin and various skin tumors using peroxidase-labeled lectin. In the normal skin, acrosyringium and distal portion of intradermal duct of eccrine and apocrine sweat glands were intensely stained with PHA. Other

We investigated the existence of lysozyme in various sweat apparatus tumors by adopting the avidin-biotin-peroxidase complex method. Positive reactions for lysozyme were found in four cases of apocrine cystadenoma, hidradenoma papilliferum, and an apocrine sweat apparatus benign tumor resembling

The histologic and immunophenotypic similarities between sweat gland carcinoma and breast cancer are well known. Indeed, these likenesses often preclude the diagnostic separation of primary cutaneous glandular neoplasms from metastatic mammary carcinomas, based on light microscopic and
