Glomus tumor: Symptoms, Diagnosis and Treatment

Glomus tumor is caused by the enlargement of the glomus body. Glomus body is a neural receptor that regulates the skin temperature.

It has three characteristic symptoms

  • Pain
  • sensitivity to cold
  • tenderness, only directly over the tumor

If you apply pressure with a pin or a pencil directly over the tumor then it is excruciatingly painful. Pressure given just to the side of the tumor produces no pain.

On examination the tumor appears as a reddish bluish blot about 4 to 8mm in size located in the deeper tissues.

Most favoured site is the hand (70%) followed by the foot. Within the hand the most common site is below the fingernail (50%).

Bone scan and MRI are helpful to diagnose tumors that are not located below the nail.

Treatment is by surgical removal of the tumor.

Frequently Asked Questions

If I delay surgery can the tumor become malignant (cancerous)?

As yet no such conversion has been reported, so it's very unlikely that the tumor will undergo malignant change.

Can the tumor recur after surgery?

Yes it can, if the excision is incomplete.

Testimonials

My compliments to you and your website. It provides the necessary knowledge and guide to bridge the gap caused by the bits of (mis)information given on most sites. Your website provides a short course on the subject. It not only guides the user, it also provides fundamental knowledge for researching the topic. Giving the user a remarkable and unmatched understanding of their topic. An ounce of knowledge makes for a better patient. I've been longing for a website such as yours. A website that is filled with information a layman can use. Its Not too complicated that it discourages the user.

Thank You for bridging the gap for me and for everyone else.
