Urogenital ImagingDermoid cyst, testicular
differs histologically from epidermoid cysts (see
epidermoid cyst testicular) in that it contains skin appendages. It is a rare
tumour of the testis, though the rarity may be partially due to misclassification of these tumours as epidermoid cysts, or to classification of the tumours as
benign monodermal mature teratomas. They present as painless testicular masses. No case of
metastasis arising from a testicular
tumour regarded as being a dermoid
cyst has been well documented, and these cysts can be considered
benign differentiated teratomas. To our knowledge, imaging features have not been specifically described. Based on the histological similarity, overlap with the imaging findings of epidermoid cysts appears likely.
