|Abstract: ||A geriatric, male castrate, American Domestic Shorthair cat was presented to Cornell
University Hospital for Animals (CUHA) for evaluation of an eccrine adenocarcinoma involving the
right metacarpal pad. Bleeding associated with the right front paw was first noticed by the owners in
August of 2003. The cat presented to the referring veterinarian on August 26th 2003, at which time an
ulcerated mass was noted on the right metacarpal pad. An incisional biopsy was obtained, and
histopathologic assessment was consistent with an eccrine adenocarcinoma. Two-view thoracic
radiographs were unremarkable. A complete blood count, chemistry panel, and urinalysis were
performed. The chemistry panel revealed renal parameters at the upper end of normal [creatinine = 2.0
mg/dL (0.7-2.1mg/dL), BUN = 33.1mg/dL (17-35mg/dL), phosphate = 13.3mg/dL (3.0-6.6mg/dL)].
Urine specific gravity was >1.045, and occasional cocci were seen in urinary sediment. The cat was
treated with enrofloxacin for the urinary tract infection.
On presentation to the Oncology Service at the CUHA, the cat was quiet but alert and
responsive. Physical examination confirmed an ulcerated mass associated with the right metacarpal
pad that measured 1.0 x 1.0 x 0.5cm. The mass was not painful on palpation, and the cat showed no
signs of lameness. Thoracic auscultation was unremarkable. Abdominal palpation revealed no
abnormalities. All peripheral lymph nodes palpated normal in size and consistency. The remainder of
the physical exam was unremarkable. A complete blood count, chemistry panel, and urinalysis were
performed. Results showed no significant abnormalities. The two lateral thoracic referral radiographs
were reviewed, a third dorsoventral view was obtained, and an abdominal ultrasound was performed.
No evidence of metastatic diseases was identified in either imaging modality. Slides from the initial metacarpal biopsy were reviewed by the CUHA Surgical Biopsy Service, and confirmed a sweat gland
The described diagnostic evaluation generated a problem list that consisted of a mildly overconditioned,
mildly stressed, geriatric, male castrated feline, with an ulcerated right metacarpal sweat
Forelimb amputation was recommended by the CUHA Oncology Service as the primary
treatment to provide local control and the best long-term prognosis. Locally aggressive resection
combined with radiation therapy was suggested as an alternative treatment, but was declined by the
owners due to uncertain efficacy.|
