Desmoplastic trichoepithelioma (DTE) is a histologic variant of TE that merits additional description.
Desmoplastic trichoepithelioma versus morphoeic basal cell carcinoma: a critical reappraisal of histomorphological and immunohistochemical criteria for differentiation.
The immunohistochemical differential diagnosis of microcystic adnexal carcinoma, desmoplastic trichoepithelioma and morpheaform basal cell carcinoma using BerEP4 and stem cell markers.
Histopathological differential diagnosis should be fibrosing basal cell carcinoma desmoplastic trichoepithelioma

Eighteen cases of morphoeic basal cell carcinoma and 19 cases of desmoplastic trichoepithelioma
were studied by Costache et al.
It is of limited value in differentiating infiltrative BCC from desmoplastic trichoepithelioma
(DTE), although BCC shows diffuse staining and DTE shows partial staining 16.
IMMUNOHISTOCHEMICAI EVALUATION OF MORPHEAFORM AND INFUNDIBULOCYSTIC VARIANTS OF BASAL CELL CARCINOMA, DESMOPLASTIC TRICHOEPITHELIOMA, TRICHOBLASTOMA, AND BASALOID FOLLICULAR HARMARTOMA USING BCL-2, K167 AND PCNA.
The purpose of this investigation was to determine whether there are differences in cellular expression of Bcl-2, Ki67, and PCNA between morpheaform basal cell carcinoma (MBC) vs desmoplastic trichoepithelioma (DTE), and between infundibulocystic basal cell carcinoma (IBC) vs trichoblastoma (TB) vs basaloid follicular hamartoma (BFH).
