The associated diseases with leprosy.

The prevalence of cutaneous, medical and surgical disorders was studied in 846 leprosy patients. Common cutaneous disorders among leprosy patients were pityriasis versicolor, tinea, pyodermas, warts, acquired ichthyosis, scabies, pediculosis and callosities. Only pityriasis versicolor had higher incidence when compared to general population. Common medical diseases were tuberculosis, infective hepatitis and diabetes mellitus. The epidemiological importance of their co-existence with leprosy is discussed and relevant literature of other diseases found to be frequently associated with leprosy is reviewed.
