Desmoplastic trichoepithelioma

Desmoplastic Trichoepithelioma (pronunciation: des-mo-plas-tic tri-ko-ep-i-the-li-o-ma) is a rare, benign skin tumor that primarily affects the face.

Etymology

The term Desmoplastic is derived from the Greek words desmos which means bond or ligament, and plastikos meaning to mold or form. Trichoepithelioma is derived from the Greek words trichos meaning hair, epithelion meaning epithelium, and oma meaning tumor. Thus, Desmoplastic Trichoepithelioma refers to a benign tumor that forms in the hair follicle epithelium and is characterized by the formation of connective tissue.

Description

Desmoplastic Trichoepithelioma is a slow-growing tumor that typically presents as a solitary, firm, skin-colored papule on the face. It is most commonly found in young to middle-aged women. The tumor is benign and does not metastasize, but it can be locally aggressive.

Diagnosis

Diagnosis of Desmoplastic Trichoepithelioma is typically made through a biopsy of the lesion. Histologically, it is characterized by islands of basaloid cells in a desmoplastic stroma, with the presence of horn cysts.

Treatment

Treatment typically involves surgical excision of the tumor. Due to its benign nature, no further treatment is usually necessary after complete removal.
