We report an infant with a rare form of epidermolysis bullosa simplex
characterized by an autosomal recessive pattern of inheritance, severe
cutaneous involvement, oral and nail lesions, association with muscul
ar dystrophy, and a poor prognosis, due to extracutaneous disease. In
addition to the usual presentation of this disease, our patient had se
vere anemia, with immature circulating white cells, and bone marrow hi
stology suggestive of a pre-leukemic state, a finding which has not be
fore been reported in the literature.
