Malignant peripheral nerve sheath tumor of the third eyelid in a 3-year-old Rhodesian Ridgeback.

A 3-year-old Rhodesian Ridgeback was presented with conjunctivitis, enlargement of the third eyelid and a dorsotemporal deviation of the right eye. A mass within the third eyelid was detected and excised. The histopathologic examination showed a malignant peripheral nerve sheath tumor, which most likely is a neurofibrosarcoma based on immunohistochemistry.

Subconjunctival hibernoma in a dog.

A 10-year-old, castrated male, German Shepherd mixed-breed dog was presented to Kansas State University Veterinary Health Center for evaluation of a subconjunctival swelling in the ventral fornix of the left orbit. The owner elected to pursue excision of the mass 2 years after initial consultation following a sudden change in the size and color of the lesion. An excisional biopsy was performed, and the mass along with its associated capsule were submitted to the Comparative Ocular Pathology Laboratory of Wisconsin for histopathologic evaluation, which confirmed the diagnosis of a hibernoma.

Evaluation of one- vs. two-layered closure after wedge excision of 43 eyelid tumors in dogs.

Objective: The aim was to evaluate how two closure techniques after full-thickness V-shaped excision relate to wound recovery and how these techniques affect eyelid function and stability of the preocular tear film.

Animals Studied: Thirty-eight dogs with 43 eyelid tumors involving <25% of eyelid margin length were included in a prospective randomized trial.

Procedures: The method for wound closure was chosen randomly before the operation.
