Left adrenal ganglioneuroma: Report of a new case

•Ganglioneuroma is a rare and benign neoplasm that arises from neural crest tissue.•It is difficult to diagnose these tumors precisely as GN preoperatively and definitive diagnosis is done by the histopathologic examination of the specimen.•Complete resection is recommended once malignancy cannot be excluded.•Assessment and management of these tumors are similar to other adrenal tumors. Adrenal ganglioneuroma (AGN) represents about 20% of the reported cases. We present a 37-year-old man referred to our institution for a history of abdominal discomfort and a left adrenal solid mass incidentally discovered in CT abdominal scan (24 × 20 mm). Patient underwent laparoscopic surgical excision of the tumor. The histopathology examination showed areas of spindle cells and scattered mature ganglionic cells compatible with AGN.
