We report the case of a 55-year-old woman who presented with a painless, slow growing, left upper abdominal mass that developed after a laparoscopic cholecystectomy. A CT scan and MRI of the abdomen revealed a desmoid tumour of the left rectus abdominis muscle.<\/jats:p><jats:p>Surgical excision was performed with an uneventful postoperative course. The histological analysis of the specimen was inconsistent with a desmoid tumour and revealed an infection of<jats:italic>Actinomyces israelii<\/jats:italic>in the anterior abdominal wall that was confirmed with a microbiology culture. The surgical treatment was followed by a course of penicillin antibiotic therapy for 6 months. This treatment resulted in full recovery with no further complications. Although it is rare, the patient\u2019s history of laparoscopic cholecystectomy was identified as the likely source of infection.<\/jats:p>","DOI":"10.1136\/bcr-2017-220357","type":"journal-article","created":{"date-parts":[[2017,5,23]],"date-time":"2017-05-23T03:45:34Z","timestamp":1495511134000},"page":"bcr-2017-220357","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Actinomycosis presenting as an anterior abdominal mass after laparoscopic cholecystectomy"],"prefix":"10.1136","volume":"2017","author":[{"given":"Zainab","family":"Alhumoud","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amro","family":"Salem","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,5,22]]},"reference":[{"key":"2025042706145246000_2017.may17_1.bcr-2017-220357.1","doi-asserted-by":"crossref","first-page":"297","DOI":"10.1089\/sur.2007.066","article-title":"Abdominal actinomycosis after laparoscopic cholecystectomy: a rare complication of bile spillage","volume":"10","author":"Ozgediz","year":"2009","journal-title":"Surg Infect"},{"key":"2025042706145246000_2017.may17_1.bcr-2017-220357.2","first-page":"451","article-title":"Actinomycosis of the abdominal wall after cholecystectomy: transferral theory","volume":"74","author":"Kooi","year":"2016","journal-title":"Neth J Med"},{"key":"2025042706145246000_2017.may17_1.bcr-2017-220357.3","doi-asserted-by":"crossref","first-page":"185","DOI":"10.1093\/omcr\/omv003","article-title":"Abdominal actinomycosis after laparoscopic cholecystectomy: an uncommon presentation of an uncommon problem","volume":"2015","author":"Tankel","year":"2015","journal-title":"Oxf Med Case Reports"},{"key":"2025042706145246000_2017.may17_1.bcr-2017-220357.4","doi-asserted-by":"publisher","DOI":"10.1089\/sur.2012.027"},{"key":"2025042706145246000_2017.may17_1.bcr-2017-220357.5","doi-asserted-by":"crossref","first-page":"542","DOI":"10.1097\/SLE.0b013e3181469069","article-title":"Intra-abdominal actinomycosis 11 years after spilled gallstones at the time of laparoscopic cholecystectomy","volume":"17","author":"Stupak","year":"2007","journal-title":"Surg Laparosc Endosc Percutan Tech"},{"key":"2025042706145246000_2017.may17_1.bcr-2017-220357.6","doi-asserted-by":"publisher","DOI":"10.1086\/510077"},{"key":"2025042706145246000_2017.may17_1.bcr-2017-220357.7","doi-asserted-by":"crossref","first-page":"345","DOI":"10.1007\/s00464-003-4247-4","article-title":"Retroperitoneal actinomycosis due to dropped gallstones","volume":"18","author":"Ramia","year":"2004","journal-title":"Surg Endosc"},{"key":"2025042706145246000_2017.may17_1.bcr-2017-220357.8","doi-asserted-by":"crossref","first-page":"43","DOI":"10.1016\/j.ijscr.2013.11.002","article-title":"Para-iliac actinomycetoma presenting as sarcoma, a late complication of appendicitis: a case report","volume":"5","author":"Navarre","year":"2014","journal-title":"Int J Surg Case Rep"},{"key":"2025042706145246000_2017.may17_1.bcr-2017-220357.9","first-page":"419","article-title":"Primary anterior abdominal wall actinomycosis","volume":"47","author":"Hefny","year":"2006","journal-title":"Singapore Med J"},{"key":"2025042706145246000_2017.may17_1.bcr-2017-220357.10","doi-asserted-by":"crossref","first-page":"315","DOI":"10.5152\/balkanmedj.2012.377","article-title":"Unusual presentations of actinomycosis;
