Use of intralesional oestradiol concentration to identify a functional pulmonary metastasis of canine sertoli cell tumour.
A seven-year-old, 31 kg male neutered Labrador was investigated for signs of feminisation syndrome and prostatic disease four years after castration and removal of a testicular sertoli cell tumour (SCT). Investigations revealed an elevated serum oestradiol-17beta concentration, a pulmonary mass containing fluid high in oestradiol-17beta and cystic changes in the prostate gland. The pulmonary mass was surgically excised and histologically confirmed to be a SCT metastasis. To the authors' knowledge, this is the first reported case of a proven functional extranodal SCT metastasis and the first to be diagnosed by oestradiol-17beta measurement of intralesional fluid.
