“…However, SHIBASAKI and ITO (1967) observed that both cell types contain approximately equally numerous mitochondria in most cases. As above mentioned, the author (KURosuMI, 1977) found the gathering of mitochondria in both luminal and peripheral cells, and this finding was reconfirmed by the present study. MUNGER (1961) stressed that the pile of mitochondria might be responsible for the reabsorption of ions to form the final hypotonic sweat.…”

“…The names of these two-layered epithelial cells have been proposed in several different ways, for instance "luminal" cell (ZELICKSON, 1961;KUROSUMI, 1977), "surface" cell (MUNGER, 1961;SHIBASAKI and ITo, 1967), "superficial" cell (HIBBS, 1958;ELLIS, 1967, 1968) and "inner" cell (HASHIM0T0 et al, 1966 for the centrally situated cell, while the "peripheral" cell (ZELICKS0N,1961;ELLIS, 1967;KURO-SUMI, 1977), "basal" cell (HIBBS, 1958;MUNGER, 1961;ELLIS, 1968;ITo, 1967) and"outer" cell (HASHIM0T0 et al, 1966) have been used for the peripherally situated cell.…”

“…The human sweat glands have repeatedly been studied with the electron microscope concerning both the secretory portion (HIBBS,1958;IIJIMA,1959;CHARLES, 1960;KURo-SUMI et al, 1960;MUNGER, 1961;ITo and SHIBASAKI, 1966;ELLIS, 1962ELLIS, , 1967ELLIS, , 1968BRIGGMAN et al, 1981) and the duct system (HIBBS,1958;CHARLES, 1960;MUNGER, 1961;213 HASHIMOTO et al, 1966;KUROSUMI, 1977;BRIGGMAN et al, 1981). However, only one paper by SHIBASAKI and ITO (1967) has dealt with the unique portion of the human eccrine sweat gland interposed between the secretory portion and the coiled duct, i.e., the "transitional portion."…”

“…These cells are called luminal cells and peripheral cells. They form a kind of stratified cuboidal epithelium and are not keratinized; in the epidermal portion of the sweat ducts the epithelium becomes stratified squamous and keratinized (KuROSUMi, 1977).…”

“…However, microvilli may also be observed in apocrine sweat glands 17 and their tumors. 22 Sebaceous carcinomas are differentiated from follicular stem cell carcinomas by the presence of lipid vacuoles that encroach on the nucleus, the common presence of areas of squamous differentiation, and the absence of follicular papillae, tubules, and pigmentation.…”

Abstract. Diagnostic records of 30 primary and one metastatic follicular stem cell carcinomas in 30 dogs were reviewed. Neoplastic cells had a clear cytoplasm and formed lobules and nests surrounded by a basement membrane. Trichoepitheliomatous and apocrine differentiations were noted in 22 of 30 (73%) and 21 of 30 (70%) primary tumors, respectively. Glycogen was present in 20 of 20 (100%) tumors tested, suggesting tricholemmal differentiation. Antibodies against AE1/AE3 cytokeratin, vimentin, and melanA/MART1 stained 29 of 30 (97%), 29 of 30 (97%), and 12 of 27 (44%) primary tumors, respectively. Small amounts of melanin were identified in 14 primary tumors, either on the hematoxylin and eosin-stained section (n ϭ 6), or on the Fontana-stained section (n ϭ 8 of 14). Ultrastructural features of neoplastic cells included cell junction complexes, swollen mitochondria, neuroendocrine-like granules, and intracytoplasmic non-membrane-bound accumulation of proteinaceous material. Features of this neoplasm are consistent with a follicular stem cell origin. Follow-up information was available for eight dogs. Metastases developed in the draining lymph node at the time of excision of the primary tumor (n ϭ 1) or subsequently (n ϭ 3).

A breast tumor is described which presented as an exophytic mass, and which by both light and electron microscopic examination had a biphasic histologic composition. In the superficial area adjacent to the epidermis, it showed tubular differentiation similar to a cutaneous tubular apocrine adenoma and salivary basal cell adenoma, and, in the deeper portion, it had the characteristic features of adenoid cystic carcinoma. Their possible interrelationships are discussed, and mammary adenoid cystic carcinoma is briefly reviewed.
