“…Actinomycosis is a difficult disease to diagnose [8] . Three important clinical presentations should prompt this diagnosis: 1. the chronicity of a mass like lesion that extends through tissue borders and mimics a tumor, 2. the development of sinus tracts that spontaneously resolve and recur, and 3. a relapsing infection following a short course of antibiotics [9] .…”

Actinomycosis is an indolent, slowly progressive, suppurative infection caused by gram-positive branching bacteria of the genus Actinomyces. The disease actinomycosis most commonly occurs in 3 body regions: cervicofacial (55% of patients), abdominopelvic (20%), and pulmonothoracic (15%). Primary infection of an extremity is an uncommon feature of actinomycosis. We present a case of rare primary Actinomycosis of the lower extremity.

“…Actinomycosis is an uncommon subacute or chronic progressive suppurative disease characterized by the formation of multiple abscesses, abundant granulation tissue, and dense fibrous tissue and may present mimicking findings consistent with either cervical or ovarian cancer [2]. Abdominal involvement classically manifests as a slow-growing mass in the ileocecal region in 65% of cases (less frequently in the stomach, duodenum, liver, rectum, or various organs), causing abdominal pain, weight loss, low-grade fever, nausea, and vomiting, making the preoperative diagnosis a clinical challenge [2,10].…”

“…In early stages, it presents as indolent infiltration, which leads to abscessation, fistulas, and fibrosis in the compromised organ; the presence of ascites, as well as the rapidly progressive evolution are exceptional [13]. Differential diagnoses include primary and metastatic neoplasms of the female genitourinary tract, endometriosis, and pelvic inflammatory disease caused by other microorganisms [10].…”

Abdominal actinomycosis is a chronic, granulomatous, and indolent disease produced by Actinomyces spp., a gram-positive filamentous bacillus, anaerobic, commensal in the oral cavity, gastrointestinal tract, and pelvic mucosa. Diagnosis is usually difficult and delayed due to its insidious presentation. It can simulate different neoplastic, inflammatory as well as infectious diseases such as tuberculosis, nocardiosis, or mycosis. In most cases, the diagnosis is made postoperatively with the histopathological report, and only 10% of them are diagnosed preoperatively. We present two cases of abdominopelvic actinomycosis simulating advanced ovarian neoplasia.
