An 8-year-old MN Husky was presented for evaluation of a palpable right anal gland mass. Abnormalities on serum biochemistry were hypercalcemia (total and ionized) and elevated BUN (32).
An 8-year-old MN Husky was presented for evaluation of a palpable right anal gland mass. Abnormalities on serum biochemistry were hypercalcemia (total and ionized) and elevated BUN (32).
Right anal gland presented mixed echogenic nodular changes with microcystic changes and focal areas of mineralization; appears encapsulated, measured 4.4 cm.
Sublumbar lymph node mass was noted with nodular expansion with similar echotexture to that of the anal gland mass measured 6 x 4 cm. The sublumbar lymph nodes are significantly vascular. The sublumbar lymph node mass was comprised of a cluster of enlarged irregular and cystic lymph nodes encompassing the iliac trifurcation and aorta. A separate fluid filled cyst or abscessation measuring 5.5 cm was also noted.
Strongly suggestive for metastatic disease. Anal gland adenocarcinoma is suspected given the history and echotexture as well as mass presentation.
FNA of the anal gland, drainage of the sublumbar lymph node and FNA of the parenchymal portions are recommended. Guarded to poor prognosis.
Anal gland carcinoma
