Abstract
Segmental Darier’s disease is an uncommon subtype of Darier’s genodermatosis, resulting
from a mutation in the ATPase type 2 during early embryogenesis. It typically presents as
a persistent, pruritic papular eruption following the lines of Blaschko. Histopathology of
Darier’s disease demonstrates acantholysis, dyskeratosis, and corps ronds. First-line
treatment includes topical retinoids, calcineurin inhibitors, and synthetic vitamin D
analogues. Severe disease may require systemic therapy with oral retinoids,
immunomodulators, magnesium, and low-dose naltrexone. Segmental Darier’s disease is
important to recognize both clinically and histologically as it may resemble other
acantholytic Blaschkolinear dermatoses and should be considered in individuals presenting
with a chronic localized papular eruption in a Blaschkoid distribution. Herein, we present
a case of a 48-year-old male with segmental Darier’s disease who improved significantly
following acitretin treatment.
