Glomus tumor

Glomus Tumor

Glomus Tumor (pronunciation: gloh-muhs too-muhr) is a rare, benign neoplasm that originates from the glomus body, a thermoregulatory shunt concentrated in the fingers and toes.

Etymology

The term "Glomus" is derived from the Latin word 'glomus' meaning 'ball of yarn', referring to the round, solid appearance of the tumor. The term "tumor" is derived from the Latin word 'tumere' meaning 'to swell', which is a common characteristic of these growths.

Definition

A Glomus Tumor is a benign, vascular neoplasm that arises from the glomus body, an arteriovenous shunt primarily found in the dermis layer of the skin. These tumors are most commonly found in the subungual region of the fingers and toes, but can occur anywhere in the body where a glomus body is present.

Symptoms

The most common symptoms of a Glomus Tumor include severe pain, tenderness, and temperature sensitivity in the affected area. These symptoms are due to the tumor's location in the glomus body, which plays a key role in temperature regulation.

Diagnosis

Diagnosis of a Glomus Tumor typically involves a physical examination and imaging tests such as MRI or ultrasound. A definitive diagnosis can only be made through a biopsy, where a small sample of the tumor is removed and examined under a microscope.

Treatment

Treatment for a Glomus Tumor usually involves surgical removal of the tumor. In some cases, radiotherapy may be used if the tumor cannot be completely removed.
