\nGlomus tumors are painful. They arise from the neuromyoarterial glomus cells found in the fingers and palms. The normal counterpart from which these tumors arise is the Suquet-Hoyer canal.

Glomus cells have a soft round to oval shape nuclei<\/span>pale eosinophilic<\/span> cytoplasm<\/span> and clearly defined cell margins (Figure 2, 3, 4).
