A study of mycetoma in eastern India.

Forty consecutive cases of mycetoma were studied with respect to clinico-epidemiological, histopathological and radiological features. The age of the patients ranged from 17 to 57 years mean being 32.4 +/- 8.68. The disease was equally distributed amongst the sexes. Most of the patients had a rural background and the disease occurred mainly among farmers and housewives. Actinomycetes (32 cases. 80%) were found to be the main pathogenic organism and Eumycetes in 4 cases (20%) only. Clinical features were more or less the same irrespective of the aetiologic agent, consisting of local swelling with discharging sinuses. History of trauma was present in only 20% cases and 80% were incidental. Foot (28/40 i.e. 70%) was the commonest site of infection. Radiological bony involvement was detected in 14 out of 18 cases examined (38.88%). Out of the 32 radiographed patients of actinomyetoma 10(31.25%) showed bony involvement whereas all the four. Eumycetoma cases radiographed, had bony involvement. The notable bony changes were sclerosis, erosions, periosteal thickening and osteoporosis.
