Аннотация
INTRODUCTION: Malakoplakia (MP) is a rare granulomatous disease, usually occurring in immunocompromised patients, linked to Escherichia coli infection. The lesions are usually located in the genitourinary tract, but there is a great variability in the topography and the clinical presentation.
CASE REPORT: A 70-year-old diabetic kidney transplant patient under immunosuppressive treatment presented with a voluminous submandibular chronic lesion, involving the skin, associated with a burgeoning lesion of the oral mucosa. Histological examination of biopsies concluded to MP and bacteriological samples were positive for E. coli. Antibiotic treatment allowed for the regression of the lesion before surgical removal. Histological examination of resected material confirmed the diagnosis of invasive MP of the submandibular gland.
DISCUSSION: The diagnosis of MP relies on histological examination, showing the presence of von Hansemann's cells and Michaelis- Gutmann bodies. The treatment is based on active antibiotics targeted against intracellular bacteria, possibly associated with surgery. We report the first case of MP involving the submandibular gland.
