Granular Cell Tumor - Clinically Presented As Lymphadenopathy

Granular cell tumors are relatively uncommon benign lesions occurring in almost any part of the body. We report the cytological diagnosis of granular cell tumor in 25-year-old male patient who presented with an inguinal mass clinically suspected to be a lymphadenopathy. Fine needle aspiration revealed polygonal cells with abundant, granular cytoplasm and eccentrically located vesicular nuclei and inconspicuous nucleoli. The histopathological examination of the surgical excision confirmed the diagnosis. If resection is complete, local surgical excision is curative for benign granular cell tumors. Granular cell tumor has a characteristic cytological appearance, and fine-needle aspiration cytology has been suggested to be diagnostic modality of choice.
