Papillomatosis of Conjunctiva and Adnexa in Dogs

Ocular or periocular papillomatosis was diagnosed in seven dogs. The periocular tumors (in 4 dogs) were located on the eyelids or the mucocutaneous junctions of the eyelids. Six of the tumors were removed surgically, using either superficial keratectomy and conjunctival dissection or lid resection techniques; the seventh was biopsied but not removed. In all cases, confirmation of the clinical diagnosis was made by light microscopy. The differential clinical considerations included squamous cell carcinoma, basal cell carcinoma, histiocytoma, and mastocytoma. In all cases of surgical removal, the dogs were free of recurrence 6 months following surgery.
