Abstract: Granular cell tumors are uncommon soft tissue neoplasms derived from Schwann cells. It is extremely rare for granular cell tumors to be found in the anterior abdominal wall, with only 12 cases of benign abdominal wall granular cell tumors reported in the medical literature to date. We report a case of an upper abdominal wall granular cell tumor in a recently postpartum 35-year-old woman. Based on the patient's history, recent postpartum presentation, and imaging findings, the soft tissue tumor was initially suspected to be a desmoid tumor. Therefore, following biopsy and resection, the final histopathological diagnosis of benign granular cell tumor was quite unusual. Herein, we discuss a unique presentation of benign granular cell tumor and its diagnostic workup, including imaging and histopathologic findings, to highlight the possibility of this rare entity in the differential diagnosis of certain abdominal wall soft tissue masses.
