Primary Gastric Actinomycosis: Case Reports and Literature Review

Abstract

Abstract Primary Gastric Actinomycosis is extremely rare. We report two cases of Primary Gastric Actinomycosis. First case, a 90-year-old gentleman with multiple co-morbidities came with post prandial non radiating epigastric pain for 2 weeks. Gastroscopy showed a submucosal gastric SOL. Endoscopic ultrasonography-guided Gastric SOL aspiration grew Actinomyces naeslundii. Second case, a 56 year old gentleman, known diabetic came with abdominal pain for 5 to 6 months and weight loss. Ultrasound abdomen revealed pyloric thickening. Upper gastrointestinal endoscopy showed gastric ulcer. Biopsies were suggestive of Actinomycosis. Cautious used of long term proton pump inhibitor in elderly and immunosuppressed individual. All efforts should be made to acquire the appropriate tissue sample for histopathology examination and culture. All actinomycosis infections need not have Sulphur pigments. Actinomycosis has a good prognosis with appropriate treatment.
