Abstract:
Fine needle aspiration (FNA) of a renal cell carcinoma with hyaline eosinophilic globules is presented. The cytology of the tumor cells was characterized by intracytoplasmic, dense, well-circumscribed globules that had a bright magenta appearance on Diff-Quik staining. Tissue sections demonstrated the globules to be located predominantly within the cytoplasm of the clear cells of the carcinoma. Immunohistochemical and ultrastructural evaluation is discussed, as is the significance of this finding.
