From: Paraneoplastic cerebellar degeneration associated with lymphoepithelial carcinoma of the tonsil
Results of the radiological and histopathological investigation of the tonsils. a and b: Whole-body PET/CT with [18F]-fluorodeoxyglucose (FDG) for tumor imaging according to the European Association of Nuclear Medicine (EANM) procedure guideline. Thick fused multi-planar reformatted images of the oropharynx in axial (a) and coronal (b) projection. Both images reveal an increased FDG uptake in the right tonsillar region suspicious for malignant tumor. c and d: Histopathology of the tonsil. HE hematoxylin-eosin [9] staining in 200 times- magnification (c) displaying sheets of atypical epithelial cells with enlarged nuclei and vesicular chromatin, intermingled by small lymphocytes and plasma cells. Pancytokeratin immunostaining (d) highlights the sheets of atypical epithelial cells (in red).
