ABSTRACT: We report a rare case of a solitary primary paraganglioma arising in the mesentery, found in a 72-year-old woman who presented with abdominal pain and a palpable abdominal mass. This extra-abdominal paraganglioma developed from paraganglionic cells that travelled by vertebral migration from the root of the superior mesenteric artery. Extra-adrenal paraganglia extend anywhere from the neck down to the base of the pelvis. Ultrasonography, computed tomography (CT), and angiography showed a solid and cystic heterogeneously enhanced mass, which was fed by the superior mesenteric artery, without distant metastasis. Exploratory laparotomy revealed a large, dark, brownish-red mass in the mesentery of the ileum, which was distinct from the ileum. The mass consisted of peripherally solid areas with central hemorrhage and cystic degeneration. It was diagnosed as a paraganglioma histologically. The patient is free from recurrence of paraganglioma after 1 year of follow up. To our knowledge, this represents only the seventh case of a paraganglioma arising in the mesentery.

ABSTRACT: We report a case of intra abdominal paraganglioma in a 46-year-old male, that measured 12.5 x 10 x 10 cm and weighed 340 grams. A CT scan was done for the evaluation of an abdominal mass. The tumour was surgically removed and followed by an uneventful post operative recovery. On follow up at one year patient had no active complaints. Histologically paraganglioma was composed of tumour cells that had abundant, granular to clear eosinophilic cytoplasm and mildly pleomorphic, vesicular rounded nuclei. Occasional mitoses was seen. No atypia was noticed. Immunohistochemistry confirmed the presence of chromogranin, synaptophysin and vimentin markers. These are diagnostic for paraganglioma.
