[Primary cutaneous aspergillosis in a leukemic child].

Primary cutaneous aspergillosis is a rare cutaneous disease that usually affects immunodepressed patients of any age. The most common associated disorders in children are leukemias and lymphomas although it can also occur in neonates and preterms due to their intrinsic immunological immaturity. We report the case of a 4-year-old boy diagnosed of acute lymphoblastic leukemia that, during chemotherapy, developed an ulceronecrotic inflammatory cutaneous lesion in the venopuncture area of the left forearm, and whose microbiological culture was positive for Aspergillus flavus.
