Bilateral temporal dacryops in a cat.

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 of the Third Eyelid in a cat.

A 9-month-old female Domestic Short-haired cat was presented with a mass of three-month duration at the base of the third eyelid of the right eye (OD). Fine-needle aspiration was carried out at another clinic, revealing clear fluid. The mass soon reformed, and the cat was referred. Ophthalmic examination revealed a pale-pink, smooth, oval mass under the conjunctiva on the anterior aspect of the third eyelid. Surgical removal of the mass was performed. Histopathology revealed a large dilated cyst together with a number of small cysts lined by simple cuboidal, and low squamous epithelium with some secretory cells. Dacryops of the third eyelid lacrimal gland was diagnosed. The eye healed uneventfully after surgery, and no recurrence was seen during one year of follow-up.

[Congenital dacryocystocele: Surgical treatment or routine follow-up?]. / Dacryocystocèles congénitales : traitement chirurgical ou simple surveillance ?

INTRODUCTION: Congenital dacryocystoceles are rare and often misunderstood pathologies. Their treatment varies and consists in simple follow-up, lacrimal catheterization or endoscopic surgical drainage, depending on medical teams. The aim of our study was to discuss the place of endoscopic drainage in the treatment of congenital dacryocystocele. METHODS: We conducted a retrospective review on 18 cases of congenital dacryocystoceles taken in charge in a tertiary care center between 2009 and 2012. RESULTS: Thirteen newborns, including five bilateral cases, were taken in charge. The average age was 14.6 days. Six newborns presented with an acute dacryocystitis at the time of diagnosis. No respiratory complications were observed. Spontaneous drainage of the dacryocystocele was observed in 38.8% of the cases, occurring at 22 days of life on average. Endonasal endoscopic drainage was performed in 66.6% of the cases. No recurrence or complication was observed after surgery. After spontaneous drainage, one recurrence was observed. The mean follow-up period of these patients was 8.8 months. DISCUSSION: Spontaneous drainage is common. Conservative management may therefore be considered in absence of infection. In case of infection and/or persistence of dacryocystocele after 4 weeks of life, endonasal surgical drainage should be considered. Imaging of the facial structure should be performed before any surgical treatment.

Multilobular lacrimal sac diverticulum presenting as a lower eyelid mass.

Lacrimal sac diverticulum is a rare condition, and its various symptoms complicate differential diagnosis. We present cases of a peculiar type of lacrimal diverticulum. A 5-year-old girl and a 50-year-old woman presented with a protruding mass inferior to the medial canthus. Each lacrimal system was patent to irrigation. The masses compressed and distorted the lacrimal passage and had no apparent connection with the lacrimal sac in dacryocystography or computed tomography. Surgical exploration and complete excision of the masses were completed. Each patient had an inverted Y- and an inverted V-shaped multilobular cystic mass that was pathologically confirmed as a lacrimal sac diverticulum. Lacrimal sac diverticula may rarely take the form of a multilobular cyst and can present as a lower lid mass. We speculate that an abnormality in lacrimal embryogenesis resulted in multiple blind pouches, a peculiar type of lacrimal sac diverticulum.
