Granular cell tumor: An uncommon tumor of Schwann cell origin

[2],[6],[7] Apart from oral, cutaneous, and subcutaneous involvement, this tumor may occur at other sites such as breast, scalp, abdominal wall, back, extremities, inguinal region, lymph node, mediastinum, soft palate, orbit, salivary glands, respiratory tract, vulva, and gastrointestinal tract. IHC further aids in the correct diagnosis of GCT as granular cells are positive for S-100, neuron specific enolase, vimentin, periodic acid-schiff, inhibin-α, protein gene product 9.5, and CD68 and negative for epithelial membrane antigen, cytokeratin, desmin, myogenin, smooth muscle actin, and Human melanoma black-45(HMB-45).
