What it is
A rare vulvar carcinoma characterized by a slowly growing ulcer or nodule which is histologically composed of demarcated nests of palisaded basal cells originating at the epidermal-dermal junction. Occasionally, the tumor may be extensively pigmented. Patients most commonly present with pruritus. The lesion is usually treated by local excision, although groin metastases have been reported.

Orphanet records these for the broader condition rather than for this specific form. They are a starting point, not a figure for this subtype — subtypes often differ, and some are defined by being rarer than the condition they sit under.
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.
