Abstract

Dowling-Degos disease (DDD) and Reticulate Acropigmentation of Kitamura (RAPK) are two distinct groups of rare genodermatoses, which fall under an umbrella of reticulate pigmentory dermatoses. Both are inherited as autosomal dominant trait with variable penetrance. Few studies have described DDD and RAPK in a single patient hypothesising that two conditions belong to a single complex disease. We describe a 32 years old male patient with hyperpigmented macules on neck, axillae, chest, lower back, forearms, hands and feet along with palmar pits and acneiform scars over face and comedo-like lesions over back since 10 years of age. The idea that both DDD and RAPK are distinct aspects of a single entity with variable phenotypic expression is further strengthened as our patient had features of both conditions. In addition, our patient had early onset DDD which is a rare feature.
