Giant Abdominal Pseudocyst: A Rare Complication of Incisional Hernia Repair With Mesh

A 79-year-old woman was referred to our department due to an abdominal wall tumor (Fig. 1). Her medical history included midline laparotomy in 1982 and strangulated incisional hernia repair (with polytetrafluoroethylene prosthesis) in 2006. Computed tomography showed a cyst measuring 31 cm × 19 cm × 17 cm on the right rectus abdominis muscle (Figs. 2 and 3). The lesion was completely resected, with primary closure of the defect and placement of polypropylene mesh. The pathology study showed evidence of granulation tissue with chronic inflammation (anterior wall), granulomatous reaction to a foreign body, fibrosis (posterior wall) and no malignancy. Pseudocyst is defined as a collection of fluid that is not covered by epithelium. There have been other denominations such as chronic seroma cyst and giant fibrous cyst, but the histology confirms the pseudocyst.
