Ultrastructural findings with granular cell tumors are highly characteristic. Pleomorphic secondary lysosomes are observed within the cytoplasm of tumor cells. [19, 20]

Features indicating neural derivation of granular cell tumors (eg, myelin residues, long-spacing collagen, arrays of neuritic processes among tumor cells) may be observed.
