Subcutaneous Chest Abscess Caused by Candida albicans Infection Following Laparoscopic Cholecystectomy in an Immunocompetent Patient: A Case Report

Cases of subcutaneous abscess due to Candida albicans (C. albicans) infection are rare, even among immunocompromised patients. To our knowledge, there have only been eleven reports of such cases in adults, all of which presented with comorbidities of immunodeficiency, prior antibiotic administration, or skin breakdown following traumatic episodes or iatrogenic procedures. We report a rare case of a 42-year-old Japanese woman with a subcutaneous abscess due to C. albicans infection. The patient was referred to our hospital with a chief complaint of gradually worsening lower left-sided chest pain. Nine months before admission, she underwent laparoscopic cholecystectomy (Lap-C) for acute cholecystitis at another hospital. She developed fever and was treated with cefotiam for three days followed by cefoperazone/sulbactam for four days. One week after Lap-C, she began to feel pain in the lower left side of her chest. The chest pain worsened gradually and the fever persisted until two months before admission. On admission, enhanced chest computed tomography revealed a left chest subcutaneous abscess located between the seventh and ninth rib. She underwent surgical percutaneous drainage, and the abscess cavity was cleaned. The pus culture revealed C. albicans, but the blood cultures were negative. We administered intravenous micafungin (150 mg daily) for 10 days, followed by oral fluconazole (600 mg daily). She experienced telogen effluvium during the period of fluconazole treatment but recovered after the cessation of fluconazole. We also present a short review of the literature relating to subcutaneous candidal abscesses in patients over 15 years old.
