Malignant paraganglioma arising from the kidney

Abstract: Paragangliomas are rare neoplasms arising from undifferentiated cells of the primitive neural crest. We report a case of a 34-year-old patient with renal paraganglioma. Complete surgical resection of the tumor was performed without intraoperative incident. The diagnosis was made based on immunohistochemical and ultramicroscopic analyses. The postoperative course was uneventful. Based on the obtained results, we discuss the clinical aspects of the case and the diagnosis.

“…Paragangliomas are tumors that arise from chromaffin cells at a variety of anatomic sites. Some of the unusual sites for paragangliomas include the kidney [1], uterus [2], and prostate [3]. Pigmented paragangliomas are very rare and less than thirteen cases of pigmented extra-adrenal paraganglioma have been reported in the English literature to date [2,4-9].…”

“…In human medicine, primary renal paragangliomas are generally treated with a combination of renal bed irradiation and/or a multi-agent chemotherapy protocol (cyclophosphamide, vincristine and dacarbazine), but results are dismal using chemotherapy, with a complete response in tumour volume in 4% of patients and partial response in 37% of patients (Niemeijer et al 2014 ; Yamamoto, Maeda & Mizoguchi 2007 ). There is insufficient literature regarding treatment options in the veterinary literature besides surgical removal, which is the only recommended treatment for all primary renal neoplasia besides lymphoma (Woldemeskel 2013 ).…”

“…Like in our case, most reported cases of renal paraganglioma showed characteristic histologic features and, when performed, a typical immunostaining pattern. However, some reported cases showed unusual histologic or IHC features, such as pigmentation [6], predominance of spindle cells [11], or absence of sustentacular cells [6]. …”
