Pharyngeal Pouch and Cleft Remnants in the Dog and Cat: A Case Series and Review

Abstract: Remnants of the pharyngeal apparatus can (rarely) form cysts. This retrospective case series describes clinical and histologic findings of such lesions. Clinical and histology databases were searched for cases of pharyngeal remnants. Eight patients were diagnosed with cysts located subcutaneously in the head and neck, adjacent to the submandibular salivary gland, near the thyroid, and in the mediastinum. Cyst linings included ciliated epithelium, and surgical excision was curative. Knowledge of pharyngeal deve… Show more

“…cats include abscess, neoplasia, foreign body granuloma, branchial cyst, thyroglosal duct cyst, thyroid and parathyroid cyst, pharyngeal remnants and sialoceles (Joffe, 1990, Giles et al, 2007, Kiefer and Davis, 2007, Nelson et al, 2012. In our study a tenacious golden colored or blood tinged fluid was aspirated from the swellings suggesting a sialocele (Kiefer and Davis, 2007).…”

“…In one study of euthyroid geriatric cats (more than 9 years of age) a palpable goiter was present in 27 of 104 (26%) of cats. Other causes of palpable cervical masses include salivary mucoceles, parathyroid gland masses or cysts, thyroglossal cysts, dermoid cysts, and pharyngeal (branchial) cysts (Norsworthy et al, 2002;Phillips et al, 2003;Lynn et al, 2009;Tolbert et al, 2009;Nelson et al, 2012). Causes of thyroid gland enlargement, other than adenomatous hyperplasia or adenoma, include thyroiditis, and thyroid cystadenoma (Norsworthy et al, 2002).…”

“…Differential diagnosis for a fluid-filled mass in the cervical region includes a cyst of thyroid, parathyroid, branchial, ultimobranchial or dermoid origin, necrotic neoplasia, salivary mucocele, and abscess (Capen, 2002; Phillips et al ., 2003; Tolbert et al ., 2009; Nelson et al ., 2012).…”
