Malignant Transformation of Multiple Familial Trichoepithelioma: Case Report and Literature Review

“…Low-grade trichoblastic carcinomas appear to be slowly enlarging, smaller than high-grade, plaques or nodules occur on the face, and do not recur if excised completely (2,(4)(5)(6). Among the cases of low-grade trichoblastic carcinoma shown in Table I variant of trichoblastic fibroinas" and the case reported by Cowen et al (5) was originally named an "unusual aggressive trichoblastoma".…”

Rare Location of a Trichoblastic Carcinoma: A Case Report

“…They are located on all the integuments including in non-classical areas for basal cell carcinomas, such as limbs or the trunk [3,4]. The peculiarity of our case is its peri-umbilical abdominal localization only one case has been reported in the literature in this location [5].…”

Locally Aggressive Trichoblastic Tumours (Low-grade Trichoblastic Carcinomas): Clinicopathological Analysis and Follow-up

“…Camille HUA 1-3# , Charles VELTER 3,4# , Amelie OSIO [1][2][3] , Céleste LEBBÉ [5][6][7] , Nicole BASSET-SEGUIN [5][6][7] , Bernard CRIBIER 4# and Maxime BATTISTELLA [1][2][3] after complete excision, there were no local or distant recurrences.…”

All these cases appear similar, characterized by a large tumour size and poorly circumscribed subcutaneous and sometimes muscular infiltration.…”
