Warty dyskeratoma

What it is

A rare, benign, epidermal disease characterized by a solitary, asymptomatic, verrucous, skin-coloured to red-brown papule or nodule, which contains a central pore and keratotic plug, occuring most frequently on the scalp, face and neck (rarely, in the mouth, under the nail plate or on the mons pubis). Occasionally, lesions may be multiple and/or pruritic. Histologically, a well-circumscribed, cup-shaped, keratin-filled invagination, with prominent acantholytic dyskeratosis, suprabasilar clefts and villi projecting into the clefts, is observed.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.

ICD-10 codes

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
