When the opening of the meibomian gland duct gets clogged the oil builds up in the gland and causes inflammation. Sebaceous adenitis and concurrent meibomian gland dysfunction MGD were diagnosed in a two-year-old mongrel dog presenting with hypotrichosis exfoliative dermatitis and blepharitis. Diagnosis of sebaceous adenitis was based on history clinical signs the histological demonstration of multifocal lymphohistiocytic and neutrophilic inflammation targeting the.

In Shih Tzus distichia occur in combination with an excessive accumulation of secretion within the meibomian glands. Ectopic cilia also arise from the Meibomian glands but emerge through the palpebral conjunctiva causing corneal irritation oftentimes even ulceration. They can occur in any breed.

Meibomian adenoma is a common tumor in dogs being estimated at 50 of all ocular tumors. This tumor may resemble cutaneous sebaceous adenoma. Histological structure is specific for the meibomian gland with the presence of foamy lobules.

Eosinophilic sebaceous cells surround basal cells in the prominent part of the tumor. Meibomian gland tumors Meibomian gland adenomas ie benign tumors and adenocarcinomas ie malignant tumors comprise approximately 60 percent of the eyelid tumors seen in older dogs. These pink to pigmented lobulated masses arise from the meibomian glands that line the eyelid margins and may become ulcerated and bleed as they become.

Several breeds are known to be predisposed to this type of cancer. This tumor may affect any area of the skin the nosenasal planum or the toes. Fine needle aspiration or biopsy may be performed for diagnosis.

We aimed to evaluate the prevalence of MGD among OSD canine patients which had been assessed by non-contact infrared meibography and interferometry and to identify MGD. Meibomian Gland Adenomas MGA are benign age related eyelid tumors which result from the accumulation of glandular material. If they become large enough MGAs can cause irritation to the cornea and conjunctiva and may reduce the normal ability to blink.

An eight year old male Labrador dog had a history of swelling on the left eyelid for the past one month. Cytological evaluation revealed individual to cluster of pleomorphic neoplastic cells with foamy background. Histopathological examination revealed basaloid cells differentiating into polyhedral cells.

Cluster of cells showing anisocytosis and anisokaryosis with fatty cyst.
