Synopsis

Warty dyskeratoma, or follicular dyskeratoma, is a relatively uncommon, benign, follicular adnexal neoplasm that usually appears between the 5th and 7th decades of life and is most prevalent in white men. The pathogenesis remains uncertain, but UV light, autoimmunity, and smoking may play a role. Human papillomavirus (HPV) infection has not been detected in these lesions.

Lesions usually present as a slow-growing, solitary, well-demarcated, skin-colored to red-brown umbilicated papule or nodule with a crusted, keratotic center. Most are asymptomatic; rarely, patients complain of pruritus or burning, and bleeding, crusting, or drainage may occur. Warty dyskeratomas are located most commonly on sun-exposed areas of the body (scalp, face, and neck). Multiple lesions, lesions involving the oral and vulvar mucosa, and subungual involvement have occasionally been reported.

Warty dyskeratomas are benign. Malignant transformation has not been reported. However, based on 3 reported cases, it has been suggested that there may be an association between the multiple warty dyskeratoma subtype and renal failure.
