Vascular lesions and inflammation visualized in scrotal skin, testicular parenchyma and pampiniform plexus. H&E staining of the pampiniform plexus (a), scrotum skin (b) and testicular parenchyma (c). Thrombos (a, b), edema and necrotizing vasculitis (b), lymphoplasmacytic inflammation (moderate diffuse lymphoplasmacytic sclerosing type orchitis) and neovascularization marked with a black arrow (c). Lesions on scrotal skin with Massonʼs stain (d) and H&E (e, f). Thickening of the stratum corneum and the spinous layer, in the papillary layer some tissue cysts can be seen together with fibrosis (d), and ectasia of the sweat glands (f). Scale-bars: 100 µm
