Clitoromegaly is a clinical manifestation of various local and systemic conditions in all species.
The external genitalia are a very rare site of primary or metastatic lymphoma in canines, with
only one previously-reported case in a dog and only sparse reports in the medical literature.
Lymphoma is also very rare in dogs less than four years of age. This account reports on a T-cell
multicentric lymphoma in a 16-month-old Basset hound presented primarily for clitoromegaly.
The patient survived for 68 days with cyclophosphamide-vincristine-prednisolone therapy.
The causes of clitoromegaly in all species, including humans, are tabulated with references.
