Plain-English summary

A 7-month-old Quarter Horse colt was brought in with a draining wound on the left side of his head that had been present since birth. The vet diagnosed the issue as heterotopic salivary tissue, which means there was salivary gland tissue in the wrong place. To treat this, the vet performed surgery to remove the abnormal tissue. After the surgery, the colt fully recovered, and the drainage stopped completely.

Abstract

Heterotopic salivary tissue was diagnosed in a 7-month-old Quarter Horse colt with a history of a draining wound in the left temporal region from time of birth. Surgical excision of the tract was performed for diagnosis and treatment. Histologically, tissues were compatible with a mixed-type salivary gland, most likely of parotid salivary gland origin. Complete resolution of the drainage was achieved after surgical removal of the ectopic tissue.
