- W2369922525 abstract "Objective To report 1 case of pigmented extraadrenal paraganglioma, which is very rare , especially occurred in the kidney, and to discuss its morphological characteristics as well as the differential diagnosis. Methods By routine formalin-fixed, hematoxylin-eosin stained sections, immunohistochemistry and electron microscopy were performed with review of the literature.Results The tumor was a 5?cm in diameter, well-circumscribed nodule located at the border of the cortex and medullary of the kidney, with black-brown color on the cut surface. Microscopically, the tumor was composed of epithelioid, rounded or angulated polygonal cells with eosinophilic or foamy cytoplasm. The parenchymal cells were arranged in the nest or acinus form with abundant vessels in the stroma giving an organoid appearance. There was a large amount of black-brown pigment granules inside the cytoplasm of the tumor cells, and sometimes in the extracellular stroma. In histochemical studies, the reticular fiber around the cell clusters was Ag-stained positive, and PAS-staining showed hyaline bodies within cytoplasm, orange-red presented by Sudan Ⅲ staining. Immunohistochemically, Syn, CgA, NSE, and NF were positive at the cytoplasm of the parenchymal cells, and S-100 was detected in the sustentacular cells, CK, EMA, Vim, HMB45, Des, HHF35, and CD34 were negative. Electron microscopy identified some neuroendocrine granules in the cytoplasm. Conclusions Pigmented renal paraganglioma is a rare tumor,and its diagnostic basis is the organoid pattern and positive neuroendocrine markers. Some benign or malignant tumors with similar morphological changes have to be taken into consideration in differential diagnosis." @default.
