Gamna gandy bodies are sclerosiderotic granules composed of various amounts of calcium and hemosiderin in hyalinised fibrous tissue. We report a case of an 18 year old girl with solid pseudopapillary tumor of the pancreas in which numerous gamna gandy bodies were present. The pathogenesis of such a finding is unclear. To the best of our knowledge, this is the first report of Gamna Gandy bodies occurring in a solid pesudopapillary tumor of the pancreas.

| » Introduction|| |
Gamna–Gandy bodies, also known as tobacco flecks or siderotic nodules, are small, firm fibrotic nodules impregnated with hemosiderin and calcium salts. They occur chiefly in the spleen. We report a case of a solid pseudopapillary neoplasm of the pancreas with numerous Gamna–Gandy bodies.

An 18-year-old girl presented with lump in the upper abdomen that was progressively increasing in size for the past 1 year. On examination, it was firm, measured 6 × 6 cm and was located in the left hypochondrium below the left costal margin. Contrast enhanced computed tomography was suggestive of a solid pseudopapillary tumor of the pancreas. Peroperatively, a mass measuring 10 × 10 cm was seen arising from the pancreas.
We received a globular tumor mass measuring 12 × 11 × 8 cm. The external surface was smooth with attached fascia and adipose tissue. Focally gray brown pancreatic tissue was seen. Serial slicing of the mass revealed a cystic tumor with presence of numerous friable, papillae arising from the wall [Figure 1]. Focal areas of hemorrhage and necrosis were identified. No area of rupture or breech of the capsule was identified. Histopathological examination was consistent with the diagnosis of solid pseudopapillary tumor of the pancreas. The tumor showed extensive hyalinization, calcification along with presence of Gamna–Gandy bodies [Figure 2]. Perls stain and Von Kossa stain confirmed that the structures were made of iron and calcium deposits [Figure 3]. Mucin secretion was present. Clusters of periodic acid Schiff positive and diastase resistant structures were seen. There was no evidence of lymphovascular invasion; mitotic activity was 1–2/10 hpf. Capsular thickness varied from 0.3–1 cm. The attached pancreatic tissue showed unremarkable histology.

Immunohistochemistry showed that the tumor was vimentin (Dako, 1:200) positive, CD 10 (Dako, 1:50) positive, and NSE (Dako, 1:100) positive. Pancytokeratin, CK7, CEA, chromogranin, ER were negative. Ki-67 (Dako, 1:60) was less than 1%.
| » Discussion|| |
Gamma–Gandy bodies are sclerosiderotic granules composed of various amounts of calcium and hemosiderin in hyalinized fibrous tissue. Occasionally a foreign body giant cell reaction is seen in their vicinity. They are usually encountered in the spleen. Rarely, they have been reported in the lymph nodes, thyroid, ovary, and liver.,, They have been described in cardiac myxoma and thymoma., Leroy et al. reported them in renal clear cell carcinoma. Kleinschmidt-DeMasters described the presence of Gamma–Gandy bodies in many central nervous and peripheral nervous neoplasms as well as schwannomas of the ulnar nerve, pituitary adenoma, cavernous angioma, myxopapillary ependymoma, and cholesterol granuloma of temporal bone.
The pathogenesis is unclear. In the spleen, they are thought to be a result of focal hemorrhage and necrosis in the splenic parenchyma secondary to congestive splenomegaly that is followed by accumulation of hemosiderin and impregnation of collagen and elastic fibers with iron and calcium. The pathophysiological process in other organs appears to be the same. The four main components of Gamma–Gandy bodies are (i) blood vessels with granulomatous vasculitis, sclerosis, and hyalinization and fragmentation of elastic fibers;(ii) deposits of calcium and hemosiderin in the vessels and in the intervening connective tissue stroma; (iii) a fibroblastic reaction along with infiltration of macrophages with multinucleated foreign body giant cells; (iv) spheroid, bamboo shaped and articulated fibers, which resemble mycelia structures or parasite eggs. This peculiar fiber formation is considered characteristic of Gamna–Gandy bodies.
To the best of our knowledge, this is the first report of Gamma–Gandy bodies in a solid pseudopapillary tumor of the pancreas.
