A Rare Presentation of Glomus Tumor as Acute Paronychia: Case Report

A glomus tumor is a benign vascular tumor derived from the modified smooth muscle cells of the glomus body. The lesions develop as small blue-red nodules that are usually located in the deep dermis or subcutis of the upper or lower extremity. The single most common site is the subungual region of the finger, but other common sites include the palm, wrist, forearm and foot. In the present study, we report the case of a 38-year-old female patient diagnosed with digital glomus tumor of Right-hand middle finger for 10 years misdiagnosed as Acute Paronychia, which on further evaluation diagnosed to be Glomus tumor, later treated with Local Excision. Histopathological examination revealed that the tumor was a well-circumscribed nodule with focal invagination of tumor cells into the adjacent upper dermis. The tumor was composed of solid sheets of cells interrupted by vessels of varying size. The majority of glomus tumors may be treated adequately by the correct diagnosis and simple excision.
