F. Constantinocasas et al., A CASE-REPORT AND REVIEW - THE GROSS, HISTOLOGICAL AND IMMUNOHISTOCHEMICAL CHARACTERISTICS OF A CARCINOMA OF ECTOPIC THYROID IN A DOG, British Veterinary Journal, 152(6), 1996, pp. 669-672
Neoplasms of the canine thyroid gland represent 5-10% of heart base ma
sses (Capen, 1978). Ectopic thyroid tissue is,detected most commonly i
n the thorax, with 23-80% of all dogs having ectopic tissue at the bas
e of the heart (Leav et al, 1976; Walsh & Diters, 1984). We describe h
ere the gross and microscopic features of a rare ectopic thyroid carci
noma in a dog and the results of an immunohistochemical study of the t
umour.
