Diffuse normolipemic plane xanthoma with underlying photosensitive dermatoses

Abstract

Diffuse plane xanthomatosis is a normolipemic non-Langerhan cell histiocytosis. Clinically, patient presents as asymptomatic yellowish plaques involving eyelids, neck, upper trunk and flexures. Usually, there is an associated haematological or lymphoproliferative malignancy which may precede or follow dermatological manifestations by many years. Rarely inflammatory dermatosis like atopic eczema, photosensitive dermatosis, erythroderma, previous scars and lymphoedema have been found to be associated with these xanthomas. We are reporting a 46-year-old male patient who had a history of photosensitivity for the last 15 years and subsequently developed diffuse plane normolipemic xanthomas.
