An 84-year-old woman with advanced breast cancer and a known inguinal hernia developed a progressively enlarging right groin mass 4\u00a0days after mastectomy. Computed tomography revealed a fluid collection, and needle aspiration confirmed an abscess. Conservative management led to temporary improvement; however, a recurrent abscess near the cecum appeared 31\u00a0days later. Surgical intervention revealed a partially perforated appendix, indicating retroperitoneal extension of appendiceal inflammation as the cause of the groin abscess, and appendectomy was performed. The patient recovered without recurrence at the three-month follow-up. Acute groin swelling in patients with inguinal hernia should prompt suspicion for appendicitis-related abscess, even without typical abdominal symptoms. Early imaging is essential, particularly in older adults with atypical presentations.<\/jats:p>","DOI":"10.1093\/jscr\/rjag466","type":"journal-article","created":{"date-parts":[[2026,5,27]],"date-time":"2026-05-27T11:41:38Z","timestamp":1779882098000},"source":"Crossref","is-referenced-by-count":0,"title":["Groin
