Actinomicosis primaria intestinal. Informe de un caso en íleon y colon. Revisión de la literatura / Primary intestinal actinomycosis in ilium and colon. A case report and review of the literature

La actinomicosis es una enfermedad crónica, supurativa e inflamatoria granulomatosa causada por bacterias filamentosas grampositivas anaerobias del género Actinomyces, siendo más frecuente Actinomyces israelii. Caso clínico: hombre de 42 años de edad con dolor abdominal, pérdida de peso de 10kg y tumor en epigastrio adherido a planos profundos. La tomografía reveló dilatación de las asas intestinales; así como engrosamiento de las paredes de colon, por lo que se pensó en proceso linfoproliferativo. Se extirparon quirúrgicamente el tumor, fragmento íleon y colon; los cuales se encontraban adheridos por tejido fibroadiposo de la serosa. Microscópicamente se observó abundante infiltrado de leucocitos polimorfonucleares y gránulos de bacterias compatibles con Actinomyces spp

Actinomycosis is a chronic, suppurative, inflammatory granulomatous disease caused by gram positive anaerobic filamentous bacteria of the genus Actinomyces, most frequently Actinomyces israelii. We report a case of a 42-year-old male presenting with abdominal pain, a 10kg weight loss and a fixed mass in the epigastrium. Tomography revealed dilatation of the intestinal loops and thickening of the colon walls; the coexistence of these two findings suggested a lymphoproliferative process. The tumour, ileum fragment and colon were surgically removed; these were adherent to the serosal fibro-adipose tissue. Microscopically, abundant polymorphonuclear infiltrate and grains of bacteria compatible with Actinomyces spp.were seen
