Insect borne diseases such as cutaneous leishmaniasis includes the topical administration of temperature controlled hot air to the skin or skull, or below the skin or skull, or directly to an internal lesion of an infected patient, with a concentrated heat source to an open outlet to raise the skin lesion temperature to a temperature capable of destroying pathogens causing cutaneous leishmaniasis and/or other viral, bacterial, fungal, parasitic or other diseases on or below the skin or skull of a patient. The invention may be administered within the body of the patient if the interior of the body is exposed during surgery. ## Claims ### Claim 1 A method of using heat therapy for treating Cutaneous Leishmaniasis, cancers including melanoma, squamous cell and basal cell cancer, and other subcutaneous carcinomas, subject to externally applied heat, abnormal pre-cancer dysplasia cells, viral, bacterial, fungal infections, tick-borne diseases, and other parasitic infections of the skin, comprising the steps of: a) placing a concentrated heated air source adjacent to and spaced from, and avoiding all contact with, during a treatment, at least one lesion on the skin of a patient containing one of said parasitic infections;
