Follicular Dowling-Degos Disease Camouflaged as Comedones: A Case Report and Literature Review.

Dowling-Degos disease (DDD) is an uncommon autosomal dominant genodermatosis that resides in the spectrum of diseases presenting with reticulate pigmentation. This disease has varied phenotypic expressions, the classical presentation being reticular pigmentation of flexures involving the axilla, submammary folds, inguinal folds, and neck. Follicular DDD is a variant of DDD with a unique presentation of folliculocentric papules, macules, pits, and comedones associated with the characteristic histological findings of follicle-centered, pigmented, branching, antler horn-like rete ridges sparing the interfollicular epidermis.

Dermatoscopy of Urticaria Pigmentosa with and without Darier's Sign in Skin of Colour.

Urticaria pigmentosa is the most common form of mastocytosis that often develops in infancy or early childhood. We report two male children- first, a 7-month-old child with a history of asymptomatic multiple dark colored skin lesions macules with wheals on gentle rubbing (Darier's sign) and second, a 2-year-old child with similar clinical presentation without Darier's sign. Dermoscopy showed dark brown lines in a reticulate pattern which is an exaggeration of the pigment network seen in the normal skin.
