A rare astrocytic tumor with rhabdoid features

Abstract: We report an extremely rare tumor presenting with rhabdoid features in the left temporoparietal lobe near the trigone in an 18-year-old Japanese man. This tumor mainly consisted of medium to large round cells that proliferated diffusely and incoherently with a scant extracellular matrix. These tumor cells had an eccentric nucleus and an eosinophilic cytoplasm containing inclusion bodies and bundles of intermediate filaments. The nuclei of these cells were vesicular with prominent nucleoli. This tumor had an ar… Show more

“…15 The immunohistochemical profile of rhabdoid GB is varied, with GFAP, EMA, vimentin, and neurofilament being common markers. 9,10,17,[19][20][21]32 Positive immunohistochemical staining of neurofilament and overexpression of vimentin offer possible markers by which to differentiate it from its parent disease, with which it shares some morphological features. 19,27 Rhabdoid GBs can be differentiated from other rhabdoid tumors of the CNS by the presence of INI-1, the hSNF5/INI-1 tumor suppressor gene product.…”

“…Rhabdoid tumor is characterized by large, morphologically monomorphous and relatively noncohesive rhabdoid cells 1–8 . It was first described as one subtype of Wilms' tumors of the kidney, presenting with rhabdomyosarcomatoid features 1,9 .…”

“…Atypical teratoid/rhabdoid tumor (AT/RT) is a representative tumor with rhabdoid cells in the CNS, 2,3 which usually arises in young children and with a highly aggressive process. Besides AT/RT, a supratentorial rhabdoid tumor, containing regions of glioblastoma, was reported and designated as rhabdoid glioblastoma 4–8 . This tumor had a specific rhabdoid morphological feature and poor prognosis.…”

“…Among these, AT/RT is the most frequent one, is usually found in infancy and childhood, and consists of rhabdoid, primitive neuroepithelial, and mesenchymal components [4]. rGBs are said to be more aggressive than typical GBs and have worse prognosis [5][6][7][8][9][10][11]. Diagnosis relies mainly on pathology, while imaging findings seem to be nonspecific as judged from a limited number of cases.…”

“…Pathological diagnosis is primarily histological, where immunohistochemistry and genetic testing is used to further characterize tumor and confirm the diagnosis [10]. So far, only 21 cases of rGBs have been reported as single case reports or small groups of patients [1,3,[5][6][7][8][9][10][11][12][13][14]. In these reports, clinicopathologic and genetic features have been emphasized and detailed evaluations of imaging findings have not been presented.…”
