Metastatic digital carcinoma in the cat: a retrospective study of 36 cats (1992-1998).

Thirty-six cats with bronchogenic carcinoma metastatic to the digit were identified. The mean age was 12.7 years, with no breed or sex predilection. Records from 19 cases were available for review. These cats presented with a primary complaint of lameness that involved primarily weight-bearing digits and the third phalanx. None had respiratory signs, despite the presence of pulmonary carcinoma. Course of disease was consistent in the 19 cases, with a mean survival time of 58 days from initial presentation. Amputation of affected digits was rarely palliative due to development of lesions in other digits and progressive nonrespiratory disease.
