Cutaneous trichilemmal cysts in three dogs.
Cutaneous trichilemmal cysts were recognized in 3 dogs. The lesions were multiple, asymptomatic, and occurred over the dorsal lumbar, lateral thoracic, dorsal neck, and cranial carpal regions. These cysts were not accompanied by other disease processes, and did not recur following surgical excision. Histologically, the trichilemmal cyst is characterized by trichilemmal differentiation of the entire cyst wall, and the formation of a predominantly amorphous and nonlaminated keratin in the cyst cavity.
