Apr 7th, 2022 - The distinction among cutaneous basaloid neoplasms such as trichoepithelioma (TE), desmoplastic trichoepithelioma (DTE), morpheaform basal cell carcinoma (MBCC), and microcystic adnexal carcinoma (MAC) can be difficult, especially in superficial b...

Dec 31st, 2021 - Cutaneous adnexal tumors are benign and malignant neoplasms that undergo morphological differentiation into cutaneous adnexa, comprising pilosebaceous, eccrine, or apocrine units. Reflectance confocal microscopy is a noninvasive diagnostic method ...

Jul 14th, 2021 - The Diagnosis: Cystic Panfolliculoma Panfolliculoma is a rare tumor of follicular origin. 1 Clinical examination can reveal a papule, nodule, or tumor that typically is mistaken for an epidermal inclusion cyst, trichoepithelioma, or basal cell carc.

Apr 27th, 2021 - Pseudocarcinomatous desmoplastic trichoepithelioma (PDTE) features verrucous squamous epidermal hyperplasia with a jagged undersurface overlying cords of follicular germinative cells in a fibrotic stroma. To date, only 5 cases have been reported. ...

Mar 14th, 2021 - Microcystic adnexal carcinoma (MAC) is a rare skin neoplasm that has not been characterized on a molecular basis. To assess expression profiles of Hedgehog (HH) signalling molecules in MAC and control tumours. Immunohistochemistry was performed fo...

Jul 14th, 2021 - The Diagnosis: Cystic Panfolliculoma Panfolliculoma is a rare tumor of follicular origin. 1 Clinical examination can reveal a papule, nodule, or tumor that typically is mistaken for an epidermal inclusion cyst, trichoepithelioma, or basal cell carc.

Jun 19th, 2019 - A shave biopsy of one of the lesions was performed that showed a proliferation of nests of basaloid cells on the dermis with palisading and rare vacuolated clear cell change. A rare ductal structure with luminal proteinaceous contents was noted.

Aug 7th, 2017 - The Diagnosis: Trichofolliculoma Microscopic examination revealed a dilated cystic follicle that communicated with the skin surface (Figure). The follicle was lined with squamous epithelium and surrounded by numerous secondary follicles, many of w.

May 23rd, 2016 - ORLANDO – Matrilin-2 – a matrix protein found in peritumoral stroma – reliably distinguished invasive basal cell carcinoma from the often difficult-to-distinguish basaloid follicular hamartoma (BFH), in a study that evaluated the protein as a mark.

First described more than 30 years ago, desmoplastic trichoepithelioma is a rare but benign adnexal neoplasm. Most often identified in middle-aged individuals and females, desmoplastic trichoepithelioma usually is a solitary annular plaque.
