What is a syringoma?

Syringoma is a non-cancerous type of skin tumour. The tumour develops from sweat glands normally found in the skin. Most patients are between 60 and 80 years old.

Where are syringomas found?

Most syringomas are found on the face, especially on the eyelids or around the eyes. Multiple syringomas may be found on the neck, chest, back, abdomen, and genital region.

How do pathologists make the diagnosis of syringoma?

The diagnosis is usually made after the entire tumour has been removed in a procedure called an excision. The diagnosis can also be made after only a small part of the tumour is removed in a procedure called a biopsy.

What is a margin?

A margin is any tissue that was cut by the surgeon in order to remove the tumour from your body. A negative margin means there were no tumour cells at the edge of the tissue. A margin is considered positive when there are tumour cells at the edge of the tissue. A positive margin is associated with a higher risk that the tumour will grow back (recur) in the same site after treatment.
