[Acro-osteolysis simulating mycetoma of the foot (pseudomycetoma)].

Idiopathic multicentric acro-osteolysis is a complex heterogenic disease that may simulate mycetoma. A ten-year-old child has developed the condition, diagnosed as mycetoma for 7 years. Medical genetic examination of the patient helped correctly diagnose the disease. Proband's younger brother suffered from the same condition. Segregation analysis has revealed a recessive sex-linked inheritance of the disease.
