Warty dyskeratoma

Warty Dyskeratoma

Warty dyskeratoma (pronunciation: /ˈwɔːrtiː dɪˌskɛrəˈtoʊmə/) is a benign skin lesion that is characterized by a central keratin plug and surrounding acantholytic dyskeratotic cells.

Etymology

The term "warty dyskeratoma" is derived from three Greek words: "wart" meaning a small, hard, benign growth on the skin, "dys" meaning bad or difficult, "kerat" meaning horn, and "oma" meaning tumor. Thus, "warty dyskeratoma" refers to a benign skin tumor with a hard, horn-like growth.

Clinical Presentation

Warty dyskeratoma typically presents as a solitary, asymptomatic, flesh-colored to brown papule or nodule with a central keratin-filled crater. It is most commonly found on the head and neck, particularly the face and scalp.

Histopathology

Histologically, warty dyskeratoma is characterized by a cup-shaped epidermal invagination filled with parakeratotic debris. The wall of the invagination shows acantholysis and dyskeratosis, with a characteristic "coronet-like" arrangement of dyskeratotic cells at the uppermost part of the lesion.

Differential Diagnosis

The differential diagnosis of warty dyskeratoma includes seborrheic keratosis, squamous cell carcinoma, actinic keratosis, and keratoacanthoma.

Treatment

Treatment of warty dyskeratoma is usually not necessary as it is a benign lesion. However, if the lesion is symptomatic or cosmetically unacceptable, it can be removed by excision or cryotherapy.
