Peritoneal splenosis mimicking carcinomatosis
AbstractSplenosis is an uncommon benign condition resulting from heterotopic autotransplantation of splenic tissues onto exposed vascularised intra- and extraperitoneal surfaces following splenic trauma and surgeries. Splenosis may be mistaken for carcinomatosis upon standard imaging techniques. A 69-year-old female patient with a past medical history of hypertension and splenic trauma, underwent total esophagectomy with polar gastrectomy for adenocarcinoma of the gastric cardia. Macroscopic examination of the surgical specimen disclosed a tumour of the cardia measuring 5 cm in greatest diameter and several dark brown nodules of the greater omentum ranging in size between 2 mm and 12 mm. Histological examination of these nodules confirmed the diagnosis of peritoneal splenosis. The authors emphasize that in patients with a previous history of splenic trauma or surgery, clinicians must consider the existence of splenosis.
