Teankum, K; Hauser, B; Grest, P; Pospischil, A; Janett, F; Bürgi, E; Borel, N (2008). Capillary haemangiomas of the scrotum and testicle in boars. Journal of Comparative Pathology, 139(4):177-186.

Abstract

In 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.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
