11 year old castrated male Labrador Retriever
Presented to NCSU Emergency Clinic on 3-19-07 for blood dripping from penis
Blood had been dripping from penis since Christmas 2006
Started on 3 week course of doxycycline for a presumed UTI, but clinical signs resumed shortly thereafter
Another course of doxycycline was prescribed for 6-8 weeks
When he presented here he was having dysuria/stranguria
Owner states that urine stream is always yellow but clots of blood will pass in the stream
rDVM felt that the bulbourethral glands were enlarged and that there was a swelling caudal to the os penis
No other relative history
Relative Findings Lungs auscult clearly with increased
bronchvesicular sounds bilaterally Prostate palpates small and symmetrical on rectal
palpation Extrusion of penis reveal no gross abnormalities
except a blood clot on the urethral orifice Caudal to the os penis a plum sized firm mass
seems adhered to underlying structures CBC – WNL, Chem panel – no significant
findings, Urinalysis USG 1.019, ph 6, 2+ proteinuria,
0-5 WBC/hpf, 0-5 RBC/hpf, culture no growth
Right medial iliac lymph node Low cellularity – small lymphocytes
Penile mass aspirate Neoplastic cells most consistent with
carcinoma but a poorly differentiated sarcoma could not be ruled out
Thoracic radiographs Possible pulmonary nodule in left caudal lung lobe
Abdominal radiographs Mineralized soft tissue mass associated with
caudal os penis Flouroscopy
Confirmed presence of pulmonary nodule CT
Two soft tissue nodules in left caudal lung lobe Soft tissue mass at caudal os penis, potentially of
urethral or os penis origin Enlarged medial iliac lymph node
Mass noted 10.5 cm from the distal end of the uretha and extended for 2 cm proximally
Pinch biopsies taken Dysplastic transitional epithelium vs
transitional cell carcinoma Bladder normal except for dilated
urethral orifices
Scrotal urethrostomy Penis amputation Histopathology
Hemangiosarcoma with clean margins Flash is going to have follow up with
