Unusual Presentation of Glomus Tumor in a Child

A 6-year-old girl presented with a large (15x10x8-cm) mass over left thumb for two years associated with severe pain (Fig.1A,B). She is resident of a remote area where medical facilities were not available. On examination, the whole left thumb is covered in mushroom fashion by fleshy mass sparing its base. X ray of hand showed left thumb soft tissue mass sparing bone (Fig.1C). Incisional biopsy confirmed it a glomus tumor. Patient was managed with thumb amputation due to extensive involvement (Fig.1D). Histopathology was consistent with round glomus cells with a sharply punched out rounded nucleus (Fig.1E).
