Abstract

Summary Atypical melanocytic lesions (AtML) are known to be associated with epidermolysis bullosa (EB), mainly with the junctional subtype. We report two cases of AtML in two female infants with recessive dystrophic epidermolysis bullosa (RDEB). Both lesions were dark brown- to black-coloured, asymmetric-shaped macules, 3-4 cm in size, with an irregular border and were located on the forearms of two unrelated, 1-year-old female infants. On a clinical and pathological basis, the pigmented macules were diagnosed as AtML in EB patients. There are only a few reports describing in detail the clinical and histopathological features of AtML in RDEB, especially in infant cases. AtML may easily be misdiagnosed as malignant melanoma and, even in infant patients with RDEB, this should be included as one of the differential diagnosis of pigmented lesions.
