“…Diseases that have been reported involving the gland in people include pleomorphic adenoma, mucoepidermoid carcinoma, adenocarcinoma, epithelial cyst, dermoid cyst, lymphoid hyperplasia, autoimmune disease, acute dacryoadenitis, orbital cellulitis, and orbital pseudotumor [10]. Masses, including adenocarcinoma and lobular adenoma involving the lacrimal gland, have been reported in dogs [22,23]. …”

BackgroundThe canine lacrimal gland (LG) and accessory lacrimal gland of the third eyelid (TEG) are responsible for production of the aqueous portion of the precorneal tear film. Immune-mediated, toxic, neoplastic, or infectious processes can affect the glands directly or can involve adjacent tissues, with secondary gland involvement. Disease affecting these glands can cause keratoconjunctivitis sicca, corneal ulcers, and loss of vision. Due to their location in the orbit, these small structures are difficult to evaluate and measure, making cross-sectional imaging an important diagnostic tool. The detailed cross-sectional imaging appearance of the LG and TEG in dogs using computed tomography (CT) has not been reported to date.ResultsForty-two dogs were imaged, and the length, width, and height were measured and the volume calculated for the LGs & TEGs. The glands were best visualized in contrast-enhanced CT images. The mean volume of the LG was 0.14 cm3 and the TEG was 0.1 cm3. The mean height, width, and length of the LG were, 9.36 mm, 4.29 mm, and 9.35 mm, respectively; the corresponding values for the TEG was 2.02 mm, 9.34 mm, and 7.90 mm. LG and TEG volume were positively correlated with body weight (p < 0.05).ConclusionsContrast-enhanced CT is a valuable tool for noninvasive assessment of canine lacrimal glands.

“…Most orbital neoplasms are extraconal and thus result in exophthalmos, often with lagophthalmos and protrusion of the nictitating membrane. An intraconal mass such as a meningioma may present as exophthalmos without third eyelid protrusion, and a small number of orbital tumours do present with subconjunctival swelling; of 15 cases of lobular orbital adenoma in a recent study, five presented with subconjunctival masses and two with retrobulbar space‐occupying lesions (Headrick and others 2004). Here, we present a benign, orbital space‐occupying lesion with an unusual presentation and with a lipomatous pathology as yet unreported in the canine orbit.…”

A 10-year-old, female, neutered Cairn terrier was presented with a progressively enlarging, cream-white fluctuant subconjunctival swelling in the right eye. A fine-needle aspirate performed under topical anaesthesia showed that the mass contained lipomatous tissue. Orbital ultrasonography showed the mass to have a distinct border and to extend into the posterior orbit. The mass was removed via a conjunctival incision. It had a distinct capsule anteriorly, while the border of the mass was less readily identified in the posterior orbit. Histopathological examination showed the mass to be a lipoma. The dog recovered uneventfully from surgery, and no recurrence has been noted after 12 months.

Canine lobular orbital adenoma: a report of 15 cases with distinctive features

Abstract: In the 15 cases reviewed, lobular adenomas of the orbit presented clinically and histologically as a benign neoplasm of lacrimal or salivary gland origin. Recurrence was likely unless the mass was completely excised, at times requiring orbital exenteration.
