Rectal endoscopy showed a submucosal tumor just above the anal canal. Fluorodeoxyglucose-positron emission tomography\/computed tomography (FDG-PET\/CT) revealed an anorectal tumor with very high FDG uptake. Aspiration cytology and needle biopsy were inconclusive, and the patient underwent trans-perineal tumor resection. The excised tumor was a 4.6\u2009\u00d7\u20093.5\u2009\u00d7\u20092.7\u00a0cm gray\u2013white bifurcated nodular tumor. Light microscopy revealed fenestrated growth of poorly dysmorphic short spindle-shaped cells with eosinophilic sporophytes. Immunohistochemical staining was positive for \u03b1SMA and desmin, negative for CD117 (KIT) and S100, and the patient was diagnosed with benign leiomyoma. Tumor cells were also positive for glucose transporter-1 (GLUT1) immunohistochemically. It is important to keep in mind that FDG-PET\/CT may show false-positive results even in benign anal leiomyoma for various reasons, including GLUT1 overexpression.<\/jats:p>","DOI":"10.1093\/jscr\/rjac101","type":"journal-article","created":{"date-parts":[[2022,3,2]],"date-time":"2022-03-02T12:07:50Z","timestamp":1646222870000},"source":"Crossref","is-referenced-by-count":1,"title":["Anorectal
