“…Actinomycetes are commonly found in the normal flora of the human oral, gastrointestinal, and genitourinary tracts. Infections usually occur when there is tissue damage or disruption of the mucosal barrier, which can lead to invasion and the progression of disease [ 4 ]. Pulmonary actinomycosis is primarily caused by the aspiration of secretions or foreign bodies containing actinomycetes from the oropharynx or gastrointestinal tract, with subsequent spread to other areas.…”

Actinomycosis is a chronic granulomatous disease that can affect various parts of the body, including the head and neck, lungs, abdominal and pelvic cavities, and wounds. It is caused by different actinomycetes like Actinomyces sherdii , Actinomyces glasii , Actinomyces cariosa , Actinomyces zurichensis , and Actinomyces europaea . Reported infections caused by actinomycetes include pulmonary actinomycosis, pelvic and abdominal infections, bone or artificial joint infections, endocarditis, complicated urinary tract infections, and soft tissue abscesses. The combination of pulmonary actinomycosis with gastric cancer is exceptionally rare in clinical practice, and the presence of actinomycetal infection alongside tumors in elderly patients poses significant challenges in treatment. This article presents the diagnosis and treatment process of an elderly patient with pulmonary actinomycosis and gastric adenocarcinoma.

“…are often very sensitive to beta-lactams, specifically penicillin and amoxicillin, drug resistance is not considered to be an issue in the treatment of this organism. Thirdgeneration cephalosporins are therefore less commonly utilized [18]. Interestingly, this microbe is not considered susceptible to oxacillin, cloxacillin, or cephalexin, while metronidazole and aminoglycosides show no in vitro action against Actinomyces.…”

The bacteria Actinomyces spp. a gram-positive bacteria responsible for the actinomycosis disease. Its 15–20% pulmonary presentation is generally chronic, progresses slowly, and might be misinterpreted as lung cancer or other long-term conditions. We describe a man in his 60s with weight loss and dyspnea. The presence of Actinomyces spp. was identified in a bronchial biopsy of the middle lobe, ruling out lung cancer as the initial diagnostic possibility. After a month of intravenously administered antibiotic treatment, the patient experienced bronchiectasis. Pulmonary actinomycosis should be considered since it is challenging to detect and sometimes mistaken for lung neoplasia or TB due to its comparable clinical and radiographic presentations. The prognosis of pulmonary actinomycosis (PA) is favorable, and it is feasible to avoid recurring complications with the correct antibiotic treatment.

“…Moreover, immune suppression can also contribute to the spread of the infection [ 3 ]. There is no literature linking smoking with abdominal actinomyces; however, there is a case reported in 2022 where a smoker developed pulmonary actinomyces that were caused by triggering inflammation [ 10 ]. It is necessary to perform further research to ascertain whether the association between smoking and opportunistic infections including actinomycosis can be established.…”

Actinomycosis is a rare opportunistic bacterial infection. It most commonly affects the cervicofacial area and is less common in the gastrointestinal area. Because of the ambiguous clinical pictures, there is a low preoperative diagnosis rate and a high rate of misdiagnoses. In this case report, we have an unusual presentation of disseminated abdominal actinomycosis in a diabetic male patient with no previous history of surgery or trauma. He presented with abdominal pain for two years. Abdominal imaging showed rectal wall thickening with adhesion and attachment to the bladder, and small bowel with omental and peritoneal deposits, mimicking colorectal cancer with abdominal carcinomatosis. Histopathological examination, however, revealed actinomyces infection with no evidence of malignancy. In such cases, the recovery rate with antibiotic therapy is very high in conjunction with surgical resection.
