“…Histopathologic characteristics include inflammation of the cyst wall and features of secretory stasis (i.e., dilated acini and ducts, epithelial atrophy) 6 . Previous reports of dacryops described interstitial dacryoadenitis in one case 11 and positive immunohistochemical staining for smooth muscle actin in three cases 12 . In the present case, the removed cyst and dilated duct were formed by a flattened, cuboidal epithelium surrounded by loose connective tissue, and the affected lacrimal gland had atrophic acini, which correlates well with what is described in the literature.…”

A case of congenital lacrimal cyst or dacryops of the lacrimal gland in an 8-month-old Neapolitan Mastiff dog is reported. The dog presented with a swelling dorsolateral to the left globe, which had been present since birth. In addition, hyperplasia and prolapse of the superficial gland of the left nictitating membrane, and bilateral macropalpebral fissure and 'diamond eye' conformation were apparent. On manual eversion of the upper eyelid, a subconjunctival mass was visible that was translucent and pink and affected the upper conjunctival fornix. B-mode ultrasonography revealed the presence of an echolucent thin-walled cystic structure measuring 15 by 12 mm and containing an echodense border and a distended tubular fluid-filled structure that extended posteriorly. A viscous and transparent fluid was aspirated from the lesion. Surgery was performed to excise the lesion, reposition the nictitans gland, and correct the morphology of the palpebral fissure. Histopathology confirmed the mass to be a cyst and distended duct of the lacrimal gland. Although tear secretion was compromised, resection of the cyst was curative.

“…In all these cases the examination of cytological smears would confirm the presence of the inflammatory process demonstrated by the increased number of heterophil granulocytes and the absence of neoplastic cells. One report describes a dacryops (orbital lacrimal cyst) in a Red-eared Slider (Chrysemys scripta elegans) (Allgoewer et al, 2002). Even though the clinical manifestations and macroscopic findings were similar to the case described here, the cytological and histopathological examination irrefutably demonstrated the different aetiology and pathology of these manifestations.…”

The authors describe a case of unilateral adenocarcinoma emerging from the Harderian gland, filling the right orbital cavity of a Florida Red-bellied Turtle (Pseudemys nelsoni). The tumour did not produce any metastasis but presented an expansive growth and led to the dislocation and protrusion of the right eyeball. Histopathological analysis revealed the presence of numerous mitotic figures in the cellular population that made up the tumour. The tumour cells completely filled the alveoli of the gland and had a nest-like structure. The authors also emphasise the importance of the differential diagnosis of this rare pathological change in turtles. Epithelial hyperplasia of the Harderian gland's duct, observed in animals suffering from vitamin A deficiency, can also lead to an enlargement of the eyelid, but in these cases the change usually involves both eyelids symmetrically. This is the first description of a Harderian gland adenocarcinoma in a Florida Red-bellied Turtle.Key words: Harderian gland, adenocarcinoma, Florida Red-bellied Turtle, Pseudemys nelsoniThe Florida Red-bellied Turtle (Pseudemys nelsoni) is a mainly herbivorous species of the Pseudemys genus. Its natural habitat is in Florida and southern Georgia. It can be distinguished from other turtle species by its distinctive red-tinged plastron and two cusps on its upper beak. The species is commonly exported for consumption and the pet trade, with approximately 50% wild-caught

To describe the differential diagnoses, investigation, and management of a periocular swelling close to the nasolacrimal duct in a horse that was consistent with a nasolacrimal duct dacryops (lacrimal cyst). A 16‐year‐old gelding, Connemara cross presented with a history of a periocular swelling rostroventral medial to the right eye that had been sampled by the referring veterinary surgeon. A cystic lesion was diagnosed following standing computed tomography. Surgical removal of the cystic lesion was performed, and the tissue was submitted for histopathologic and immunohistochemical examination. Surgical removal of the cyst was curative, and there was no recurrence of clinical signs 7 months later. There was a small amount of mineralized material in the center of the cyst. Histopathologic and immunohistochemical examination confirmed a nasolacrimal duct cyst. Dacryops can form in horses as well as other species and appears to have a favorable outcome if surgically removed.
