“…; Kelmer et al . ). The fact that the fluid aspirated from the cyst contained cholesterol crystals on histological examination supports the diagnosis of a cyst of branchial remnant origin (Titchener and Allison ), but cholesterol crystals may also indicate the site of an old haemorrhage or tissue necrosis and are therefore not a significant finding.…”

“…Immunohistochemistry may have helped to visualise C cells in the mass, but it was not performed in the current case. An origin from the thyroglossal duct was also a possible diagnosis of a cyst located within the thyroid gland, but such a cyst would have been lined by cuboidal thyroid epithelium (Joffe 1990;Jubb et al 2007;Kelmer et al 2007). The fact that the fluid aspirated from the cyst contained cholesterol crystals on histological examination supports the diagnosis of a cyst of branchial remnant origin (Titchener and Allison 1989), but cholesterol crystals may also indicate the site of an old haemorrhage or tissue necrosis and are therefore not a significant finding.…”

Summary A one‐year‐old female trotter was examined for an enlarging mass on the proximoventral aspect on the right side of the proximal cervical area. On clinical and ultrasonographic examination the mass was found to be a fluid filled cavity of approximately 8 cm in diameter surrounded by a capsule. The right lobe of the thyroid gland was closely related to the mass. The mass and the right thyroid gland were surgically excised. Histological examination revealed an ultimobranchial cyst. This is the first description of the diagnosis and treatment of a thyroid cystic abnormality related to the fifth branchial pouch (ultimobranchial body) in a horse.

“…Subepiglottic cysts may less frequently be associated with coughing, swallowing disorders and aspiration pneumonia (Koch and Tate 1978). The condition is most commonly diagnosed in young Thoroughbred (TB) and Standardbred racehorses and is thought to be congenital (Fulton et al 2012), with cysts arising from a remnant of the thyroglossal duct (Kelmer et al 2007). However, it has also been reported that SECs may be acquired secondary to inflammation or trauma and they are occasionally found in older horses with no previous history of upper respiratory tract problems (Davenport-Goodall and Parente 2003;Aitken and Parente 2011).…”

Summary Subepiglottic cysts (SECs) are an infrequent cause of upper respiratory tract noise and exercise intolerance in horses. They may also be associated with no clinical signs and be an incidental finding during routine upper airway endoscopy. The aim of this study was to assess the effect on performance of horses undergoing surgical removal of SECs. The case records of 15 horses (1995–2009) diagnosed with SECs were retrieved. Eleven (73%) of the 15 horses included in the study were Thoroughbred racehorses. Eleven (73%) of the 15 horses had no preoperative clinical signs related to the SECs, with the remaining 4 (27%) having a respiratory noise (n = 4), nasal discharge (n = 1), difficulty swallowing (n = 1) or a cough (n = 1). Endoscopic examination in the standing horse was diagnostic in 93% (n = 14) of horses. Nine (82%) of the 11 Thoroughbred horses were yearlings, of which only one horse (11%) presented with clinical signs consisting of a respiratory noise and nasal discharge. Four of the 11 (36%) Thoroughbred horses were found to have concurrent epiglottic entrapment. Surgical removal was successful in all cases. Eight of the 11 (73%) Thoroughbred horses in this study raced following SEC removal. The majority of SECs are identified during routine endoscopic examinations and are not associated with clinical signs. The prognosis following surgical removal of SECs is good and future performance does not appear to be affected.

“…In the preceding paper, Kelmer et al (2007) describe en bloc resection of a thyroglossal duct cyst located adjacent to the thyroid, a previously unreported location for such a cyst. They also review other types of developmental cysts that should be considered as differential diagnoses and briefly mention treatment.…”
