“…It is likely that DTE preceded pseudocarcinomatous hyperplasia, and that subsequent development of pseudocarcinomatous hyperplasia brought it to clinical attention. The presence of trauma-related changes (erosion and scale crust) in our three cases, and the history of trauma/picking in the case reported by Rossi et al 6 suggest that pseudocarcinomatous hyperplasia may have arisen because of trauma. However, the possibility that pseudocarcinomatous hyperplasia developed solely as a response to the underlying DTE cannot be excluded.…”

“…A comprehensive review of pseudocarcinomatous hyperplasia published in 2011 does not include DTE in a list of disorders associated with pseudocarcinomatous hyperplasia . To the best of our knowledge, only two cases of DTE with pseudocarcinomatous hyperplasia have been reported in the English literature . In both cases, the tumors developed on the face of 12 year old boys, and were originally misdiagnosed as SCC.…”

We report three cases of desmoplastic trichoepithelioma (DTE) with overlying pseudocarcinomatous hyperplasia. All three cases developed on the face of patients in their second decade. In spite of their young age, a diagnosis of squamous cell carcinoma was considered for each case, given the unusual juxtaposition of these two well-known simulators of malignancy. Awareness of this potential association may avert a misdiagnosis of malignancy.

“…The lesions were clinically misdiagnosed in most cases. Misdiagnosis included squamous cell carcinoma (SCC) , sebaceous hyperplasia , and BCC , as in our first case.…”

“…The histopathologic differential diagnosis also includes BCC, SCC, and microcystic adnexal carcinoma. Shave biopsies can make it difficult to distinguish DTs from malignant tumors such as well‐differentiated SCCs because desmoplastic trichoepithelomas can produce a reactive pseudoepitheliomatous (pseudocarcinomatous) process. In difficult cases, immunohistochemistry markers such as cytokeratins 20, 10, 15, and d2‐40, usually positive in DT, may confirm the diagnosis .…”
