====Diagnosis====

====Diagnosis====

'''Cytology''' of the mass will reveal large hepatoid cells with a round, central nuclei, multiple nucleoli, and an abundant cytoplasm. There may be concurrent inflammation or haemorrhage. Cytology cannot distinguish adenomas from [[Adenocarcinoma|adenocarcinomas]], and further investigations should be carried out if malignancy is suspected.

====Treatment====

'''Castration''' is the treatment of choice and 95% of tumours will regress. Administration of oestrogens or anti-androgens can also be considered, but side-effects of those hormones should not be forgotten. Surgical removal of the tumour may be necessary if it is large, or in females.
