Lycopodium granuloma.
The spores of Lycopodium (L) clavatum were used as a component of a dusting powder in many hospitals during the 1920's and 1930's. When L spores enter surgical wounds a lesion clinically resembling tuberculosis or neoplasia may develop months or even years later. We recently encountered a case of L granuloma occurring in a patient 50 years after an appendectomy. Three additional cases found in the files of the AFIP are also reported.
