Bilateral corneoconjunctival dermoids and nasal choristomas in a calf

Abstract

A 5-day-old Angus x Hereford calf presented for bilateral haired masses on the eyes and nasolabial planum since birth. The masses were surgically excised from the inferonasal cornea and bulbar conjunctiva of both eyes and the left and right side of the dorsomedial nasolabial planum. Histopathology of the excised tissue confirmed bilateral corneoconjunctival dermoids with ectopic lacrimal glands, and bilateral nasal choristomas and ectopic nasal glandular tissue. Surgery was curative and healing was uneventful. Bilateral ocular dermoids in combination with nasal choristomas and ectopic glandular tissue have not been documented previously in cattle.

Ocular Dermoids in Crossbred Indian Cattle: A Comparative Evaluation of Four Year (2012 - 2015) Study Results and Literature Reviews

“…Of the five cases in our study, the predominant dermoid was ventrolateral corneoconjunctival dermoid. An increased incidence of ventrolateral corneoconjunctival was also reported by Barkyoumb and Leipold (1984) and Yeruham et al (2002) compared to the inferonasal corneoconjunctival dermoid reported by Brudenall et al (2008) and Roh et al (2014). However, both ventrolateral and inferonasal corneoconjunctival dermoids have been described in crossbred Indian cattle (Bhatt et al, 1964;Bose et al, 1982;Bose and Karimullah, 1984;Purohit et al, 1987;Ansari and Moulvi, 2013).…”

“…Dermoids have been reported frequently in dogs (Barnett et al, 2002;Bodh et al, 2015) and cattle calves (Al-Badrany et al, 1989;Yeruham et al, 2002;Roh et al, 2014), less in cats (Glaze, 2005) and rarely in other domestic animals like horse ( Joyce et al, 1990;Greenberg et al, 2012), donkey (Misk et al, 1994), buffalo (Rezaei et al, 2007), goat (Pimentel et al, 2007), sheep (Bukar et al, 2008), camel (Moore et al, 1999) and pig (Brightman et al, 1985), wild animals like white tailed deer (LaDouceur et al, 2012), red deer (Gelmetti et al, 2010), lion (Robinson and Benirschke, 1981) and wildebeest (Weber and vanHoven, 1990), birds like parrot (Leber and Burge, 1999) and goose (Busch, 1985), laboratory animals like rat (Nichols and Yanoff, 1969), rabbit (Styer et al, 2005), guinea pig (Otto et al, 1991;Wappler et al, 2002) and even in humans (Pirouzian, 2013). Among cattle, the condition has been evaluated and reported exclusively in native Korean cattle (Roh et al, 2014), Hereford cattle (Barkyoumb and Leipold, 1984;Brudenall et al, 2008) and Israeli-Holstein breed (Yeruham et al, 2002). Although sporadic occurrence of the condition has been reported in crossbred Indian cattle calves (Bhatt et al, 1964;Misra and Angelo, 1979;Bose et al, 1982;Purohit et al, 1987;Sarma and Sarma, 1989;…”

Collagenous choristoma at the cerebellar peduncle of a Nelore bull

“…Oliveira et al (2009) described a pulmonary choristoma associated with a meningocele in a bovine; however, the animal did not present any neurological signs and the mass was located at the subcutaneous tissue of the frontal region of the skull, preventing cranial symphysis closure. Prevalence studies providing evidence of which age range is the most frequently affected were not found; however, according to Bassi et al (2010), Brudenall et al (2008) and Oliveira et al (2009), choristomas have a higher occurrence in young cattle.…”

“…Case descriptions of choristoma in domestic animals are uncommon to rare (WHITTEN et al, 2006), with reports in cattle (BASSI et al, 2010;BINANTI et al, 2012;BRUDENALL et al, 2008;OLIVEIRA et al, 2009), canines (BENTLEY et al, 2006WHITTEN et al, 2006) and felines (FRANÇA et al, 2010). In cattle, there are descriptions of different tissues proliferating within the thoracic cavity, diaphragm, retroperitoneal region, adrenal gland region, and subcutaneous tissue (BASSI et al, 2010).…”

“…In cattle, there are descriptions of different tissues proliferating within the thoracic cavity, diaphragm, retroperitoneal region, adrenal gland region, and subcutaneous tissue (BASSI et al, 2010). The ocular region is another described location for choristomas, frequently termed ocular dermoid, that usually present as a unilateral lesion (BRUDENALL et al, 2008), with a similar low prevalence in all breeds, other than the Hereford (BARKYOUMB; LEIPOLD, 1984). Oliveira et al (2009) described a pulmonary choristoma associated with a meningocele in a bovine; however, the animal did not present any neurological signs and the mass was located at the subcutaneous tissue of the frontal region of the skull, preventing cranial symphysis closure.…”
