Exocrine differentiation of trichoepithelioma & desmoplastic trichoepithelioma; a scanning electron microscopic study. Indian Journal of Pathology & Microbiology. 1993 Apr; 36(2): 101-3http://imsear.searo.who.int/handle/123456789/72753Trichoepithelioma is widely thought to be a benign appendage tumour which arises from hair follicles (i) Scanning electron microscopy reveals that the basement membrane of Trichoepithelioma & desmoplastic Trichoepithelioma is similar to the basement membrane of exocrine glands like sweat or sebaceous gland. The basement membrane of Trichoepithelioma and desmoplastic Trichoepithelioma do not show any difference in their structure. Thus, possibly Trichoepithelioma and desmoplastic Trichoepithelioma arises from exocrine gland and are closely related to each other.engBasement Membrane --ultrastructureExocrine Glands --ultrastructureHair Diseases --pathologyHumansMicroscopy, Electron, ScanningNeoplasms, Basal Cell --ultrastructureSkin Neoplasms --ultrastructureComparative Study
