Bilateral temporal dacryops in a cat

Abstract

A 1‐year‐old Maine Coon female spayed cat was presented for a 7‐week history of bilateral pinkish masses located over the dorsotemporal conjunctival quadrants. Ophthalmic examination revealed the presence of bilateral temporal, slightly hyperemic, subconjunctival masses, fluctuant, and nonpainful. The remainder of the ocular examination was unremarkable. Ultrasound biomicroscopy and B‐scan ultrasonography confirmed the presence of a bilateral cavitated and tubular structure, extending within the temporal orbit, with anechoic fluid‐like content. Surgical removal was performed. Histopathology described the lesions as lacrimal gland tissue, markedly infiltrated by inflammatory cells, associated with cavitated structures filled with proteinaceous debris, and lined by flattened bilayered cuboidal epithelial cells. Bilateral adenitis of unknown origin and dacryops of the temporal lacrimal glands were diagnosed. Both surgical sites healed uneventfully, and no recurrence was reported on either eye during a 12‐month follow‐up period.

Dacryops with dacryolithiasis in a dog

“…Dacryops, although rare, have been mostly reported in young dogs aged 3.5 months to 1 year (Cullen & Grahn, 2003;Delgado, 2013;Lamagna et al, 2012;Ota et al, 2009;Playter & Adams, 1977). Two reports of dacryops in cats also occurred in 1-year-old and younger cats (Maggio, 2020;Sritrakoon et al, 2016). In fact, dacryops is generally considered a congenital disorder in animals (Giuliano, 2013;Leiva & Gimenez, 2018), hence the diagnosis at a young age.…”

“…Frequent reports in young basset hounds and Labrador retrievers (Ota et al., 2009; Playter & Adams, 1977) suggest a congenital condition and a presumed predisposition in those breeds (Giuliano, 2013; Leiva & Gimenez, 2018; Ota et al., 2009; Pickett, 2018). Dacryops have also been reported in the German shepherd dog (Cullen & Grahn, 2003), Neapolitan mastiff (Delgado, 2013), golden retriever (Lamagna et al., 2012) and cats (Maggio, 2020; Sritrakoon et al., 2016). A dacryops is suspected based on clinical signs and location (Pickett, 2018).…”

A dacryops is suspected based on clinical signs and location (Pickett, 2018) exploratory excision of the pathologic tissue, which is also the treatment of choice for this condition (Leiva & Gimenez, 2018;Pickett, 2018).…”
