摘要

abscesses, evolving, chronically, to dissemination of the infec tion to the adjacent soft tissues, then the fascial planes, exter nalizing itself through fistulas of the skin and paranasal sinuses. However, it is rarely seen in combination with osteomyelitis(3).On computed tomography, actinomycosis appears as a mass with ill-defined borders, soft-tissue density, and contrast en hancement, together with fluid collections and fistulas. The dif ferential diagnosis includes fungal ulcers, carcinoma, idiopathic midline granuloma, and osteomyelitis of the maxilla caused by other germs(5). In the histopathological analysis, hematoxylin eosin staining reveals chronic abscess with polymorphonuclear leukocytes, granulation tissue and fibrosis, Grocott's staining revealing colonies of bacilli forming "sulfur granules", which represent tangled filaments of Actinomyces, present in abscess es, exudates of the sinus tract, or tissues infiltrated by the le sions(3,6).Penici.
