SummaryIn boars, scrotal haemangiomas have been described frequently, but intratesticular haemangiomas are rare. Of 12 boars with scrotal haemangiomas, three animals also had testicular tumours, as follow: testicular haemangioma (TH) (n = 1); TH with intratubular germ cell tumour (ITGT) (n = 1); TH with intratubular germ cell-like tumour (ITGLT) and Sertoli cell tumour (n = 1). In the nine remaining boars, no testicular tumours were found. Immunohistochemical examination of scrotal and testicular haemangiomas revealed labelling of endothelial cells for vimentin and factor VIII-related antigen. Labelling of smooth muscle actin was occasionally observed in the walls of neoplastic vessels. In the ITGT, no labelling was produced by any of the antibodies used. The Sertoli cell tumour was strongly positive for S-100. Sperm granulomas and degeneration of seminiferous tubules were also observed.
