The development of spontaneous multiple tumours is a rare event in domestic rabbits. The diagnosis of a cutaneous basal cell tumour and the successive development of simultaneous bilateral testicular tumours with dissimilar histology (a seminoma and an interstitial cell tumour) are described in a vasectomized, crossbred dwarf rabbit, aged 6 years. Two cases of basalioma associated with uterine adenocarcinoma have been previously described in rabbits. A similar association between basal cell neoplasia and development of tumours (e.g., testicular and breast cancer) at cutaneous and non-cutaneous sites has been reported in man.
