Reticulate Acropigmentation of Dohi

A 15-year-old boy presented with complaints of asymptomatic hypo and hyperpigmented spots over dorsa of the hands and feet since birth. There was family history of similar complaints in father and paternal grandfather in the same distribution. There was no history of photosensitivity, photophobia or darkening of the lesions on sun exposure. On cutaneous examination, multiple hypo and hyperpigmented macules were present in symmetrical distribution over dorsum of both hands and feet. There were multiple freckles on his face. There were no palmar pits and his mucosae were normal [Figure 1]. The patient’s intelligence was normal and his systemic examination revealed no abnormality. Based on history and clinical examination [Figure 2], a diagnosis of reticulate acropigmentation of Dohi was made. Acropigmentation of Dohi has to be differentiated from other pigmentary disorders such as reticulate pigmentation of Kitamura and Dowling–Degos disease.^[1] We present this case due to its rare occurrence. Identifying and differentiating the condition from other pigmentary dermatoses is important for appropriate counselling and prognostication.
