Subcorneal Pustular Dermatosis in Paediatrics: A Case Report and Review of the Literature.

Subcorneal pustular dermatosis (SPD) is a rare chronic condition rarely seen in adolescence and childhood. The exact etiology of the disease remains unknown. In this paper, we report the case of a 14-year-old girl who came with a history of itchy skin lesions confined to the upper and lower extremities, thighs and pubic area for two months. Physical examination showed well-demarcated annular brownish plaques, ranging in size from 5cm to 7cm, in addition to a scaly and elevated border with few pustules noted over the upper and lower extremities, thighs and pubic area. Some lesions also showed central clearing. New annular vesicular lesions were also noted on the lower extremity and inner thigh. She was diagnosed with SPD based on the characteristic clinical and histological features. The patient was treated with Dapsone and showed good clinical response.
