Incidence and changing pattern of mycetoma in western Rajasthan.

Histopathologic analysis of 73 cases of mycetoma occurring in western Rajasthan was done from January 2001 to December 2005. Maduromycotic mycetoma remains commonest in this region as compared to actinomycotic mycetoma, which is more common in the southern part of Rajasthan. The incidence of actinomycotic mycetoma has increased during the last five years in this part of Rajasthan due to changes in climatic conditions, like heavy rainfall, increased irrigation by Rajasthan Canal, urbanization of villages, and modification in agriculture. The ratio of prevalence of maduromycotic mycetoma to the prevalence of actinomycotic mycetoma has decreased from 4:1 to 1.91:1 during the last five years in western Rajasthan.
