title: Malakoplakia of palatine tonsil.
abstract: This paper's purpose is to document a case of unilateral tonsillar malakoplakia. Escherichia coli was repeatedly cultured from the lesion, and the isolate was studied by expert microbiologists who found no abnormalities in its biologic properties. The course of the lesion was followed by repeated punch biopsies before, and after the institution of antibiotic therapy. Following treatment, healing was characterized histologically by the disappearance of edema, granulocytes and bacilli, a striking initial increase in the number of Michaelis-Gutmann (MG) bodies and other calcified particles, and an increase in the number of foamy plasma cells, before the eventual resolution of the lesion.
