INTRODUCTION: Glomus tumor is rare benign tumor of glomus cells
commonly found in the subungual region.
34) Glomus tumor differs from sclerosing perineurioma in that glomus cells
have more abundant cytoplasm and diffusely express actins but not EMA.
Histopathology report on routine haematoxylin and eosin stain came as thin intact fibrous capsule surrounding the tumor composed of varying population of glomus cells
(monotonous round cells with pale eosinophilic cytoplasm with well-defined cell borders with occasional spindle shaped cells and mast cells; large central round or oval punched out chromatin, uniform nucleus and scanty cytoplasm) with tortuous vascular spaces containing blood and lined with endothelium scattered between the tumor cells.
In the solid areas, dense accumulations of glomus cells
and blood vessels were seen.
