Disseminated panarteritis was found in 16 (9 males and 7 females) of 49 laboratory beagle dogs (25 males and 24 females) from one breeding kennel. The dogs had been used in a 6-month oral toxicity study. Panarteritis was not associated with clinical or gross abnormalities. The incidence was similar in the control and test article-treated groups. Mainly medium-sized arteries throughout the body, particularly intercostal arteries (at their aortic origin), and coronary, epididymal and thymic vessels were affected. Chronic mononuclear-cell periarteritis was the predominant feature. Mixed cellular inflammation of the wall, proliferation or degeneration of muscle cells, focal "fibrinoid" material in the tunica media, fragmented internal elastic lamina and intimal thickening associated with myointimal cellular proliferation also occurred. These histologic changes are compatible with those of immune arteritis. Round worm intestinal infestation and granulomas of visceral larva migrans were common in several organs. Statistical analyses suggested that the pedigree of dogs is related to panarteritis, but the presence or absence of parasitization alone is not. The possible roles of genetic predilection and/or parasites in the pathogenesis are discussed. This panarteritis is spontaneous and may complicate the interpretation of lesions in toxicity studies.

The Authors describe chronic vaginitis of bovines in intensive breeding. All of the 78 subjects examined presented vaginitis, accompanied by fibrinous hydrocele. On the spermatic cord and the tail of epididymis, initial lesions consisted of granulomas and fibrinous bridges between vaginalis propria of testicle and of epididymis. Subsequently appeared adherence and synechiae, which join the deferens and epididymis body to didymis, and thickening of albuginea. Synechiae can develop between peritesticular vaginalis propria and communis. Histopathological findings: peritoneal-like papillary structures with metaplastic mesothelial cells; diffuse lympho-plasmacellular infiltration with eosinophils and mast cells; intense capillary angiogenesis. The epididymal lesions are: diffuse mononuclear infiltration; periarteritis nodosa; papillary proliferations of endothelium; endothelial degeneration; tubular ectasia and stenosis; intraepithelial cyst. Noticeable within testis: periarteritis nodosa; fibrosis of albuginea; spermatocytes vacuolisation; multinucleate spermatids; epithelial shedding. The Authors pointed out: the serological and bacteriological testings furnished inconclusive results; only pathological finding always present is a large infestation of cremasteric muscle with Sarcocystis, to which is attributed the etiopathogenesis of flogosis, that is chronic from the beginning. The Authors propose the terminology of "Chronic peritesticular and periepididymal vaginitis" or "Chronic Periorchitis and periepididymitis".

The authors report on two isolated cases of bilharzioma: one vesical revealed by an hematuria and one epididymal constituting an intrascrotal mass. Clinical signs did not oriented toward these diagnosis and biology was helpless. Serodiagnosis by hemagglutination was negative, but immunofluorescence was more reliable. On the contrary both tumors were detected by echotomography of which the efficiency is determinant for the diagnosis and must be underlined. Only anatomopathology was able to confirm the diagnosis of tumor. As a matter of course, surgical exploration and excision are necessary in these types of tumors with negative biology. In both cases, effects were isolated. In one patient, infestation was old and already treated; in the second one, infestation was probably light. The authors recall also bilharzioma physiopathology. Frequency of vesical bilharzioma is about 20% of genito-urinary schistosomiasis while epididymal bilharzioma reaches only 0.29 to 4.8%. Direct line between bilharzioma and cancer is likely but controversial, schistosomiasis beeing a true irritative agent.

Isolated tuberculous orchitis is a rare entity. The coexistence of tuberculosis of the testis with filarial worm infestation is even more rare. In this report, we present a case of tuberculous involvement of the testis, associated with filarial worm infestation in the spermatic cord that presented as a testicular tumor. A 55-year-old male presented with unilateral testicular swelling of four months duration. As the clinical evaluation was suggestive of testicular malignancy, he underwent a right high orchidectomy. The histopathology report revealed isolated tuberculous orchitis without epididymal involvement along with filarial infestation of the spermatic cord.
