Initial diagnosis was performed through percutaneous fine-needle aspiration biopsies, which yielded cytologic smears exhibiting highly characteristic rhabdoid cells, i.e., cells with a large, vesicular nucleus with a prominent nucleolus and cytoplasm exhibiting a large, dense, paranuclear inclusion. Interphase FISH demonstrated only one signal (heterozygous… CONTINUE READING
