Treatment of oral histoplasmosis by local injection with nystatin.

Abstract

As yet, no specific therapy for histoplasmosis has been developed clinically. The effective inhibitory nature of nystatin on Histoplasma capsulatum has been demonstrated both in vitro and in animals experimentally infected.1On this premise, we injected nystatin solution directly into oral lesions of histoplasmosis and observed the gradual but complete disappearance of the localized disease process.

The lesions were distributed as follows: two nodules on the upper and one on the lower labial mucosa,
