Warty Dyskeratoma

Excerpt

Warty dyskeratoma is an uncommonly encountered benign proliferative epidermal disorder. However, its name can be misleading, as there is no relationship between this disorder and human papillomavirus (HPV) infection that causes common warts. Histologic features suggest that this benign growth is a follicular neoplasm. Therefore, some suggest naming this entity as a "follicular dyskeratoma." In 1954, Helwig introduced a case of an "isolated dyskeratosis follicularis" due to its similarities with the dyskeratotic papules observed in Darier disease. However, he noted that these isolated lesions were solitary and double or triple the size of the papules found in Darier disease.

Szymanski first used the term warty dyskeratoma to summarize the salient features of the condition. These features include the common warty clinical morphology, the principal histological finding of dyskeratosis, and "-oma" denoting the tumor-like nature. Ackerman suggested that the term warty dyskeratoma should be restricted to nodular lesions. He proposed that the papular lesions would be better referred to as the papular form of focal acantholytic dyskeratosis.
