[Anatomopathologic changes in the testis following prolonged treatment with LHRH agonists. Experimental study in rats].

Presentation of a study conducted on 20 male Wistar rats treated for 3 months with Leuprolide (LHRH agonist). Analysis of pathophysiological testicular changes resulting from the treatment and extent of recovery at 3 months of therapy discontinuation, relating those changes to testosterone plasma levels in peripheral blood. Serum testosterone fell to 1.17 +/- 0.30 ng/ml in the treated group, shifting to figures overlapping with normal values within 3 months of discontinuing treatment. Such decreased testosterone levels translate into significant testicular histological damage. Three months after interruption of treatment there is nearly complete recovery of such damage, with just around 10% tubules without spermatozoa, with unchanged germinal line. We conclude that the marked suppression in testosterone levels caused by LHRH agonists translates into a significant degeneration of the seminiferous tubule, which appears to be reversible 3 months after treatment discontinuation.

[Pulmonary leiomyosarcoma].

We present the case of a young patient with leiomysarcoma of the lung that was at first diagnosed as a hydatid cyst. Pathological tissue analysis was needed for firm diagnosis. This rare tumor, of which fewer than 100 cases have been reported worldwide in the literature, needs to be considered as a differential diagnosis when lung cancer is suspected, given that leiomysarcoma has a better prognosis. Treatment is mainly surgical.

[Melanoma of the nasal cavity].

Presenting a case of nasal Melanoma, in a patient previously diagnosed and treated from Rhabdomyosarcoma of the same nasal cavity. In our Department has been treated with surgery plus thymostimulin (TP-1 Serono) after surgery. Subject reviewed and clinic features, diagnostic difficulties and nowadays immunotherapy commented.

[Polyarteritis nodosa as a cause of sensory motor polyneuropathy.Apropos of a case].

We present a case of nodose polyarteritis (NPA) in a 65-years-old man with clinical manifestations at the level of the peripherical nervous system (PNS) as a subacute sensorimotor polyneuropathy. We believe that this is an interesting case due to the outlined symptomatology and the first clinical signs, not as common as the multiple mononeuropathy. The diagnosis was established through biopsy of muscle-nerve, without observing aneurysms at the Divas and with negative results for the Hepatitis B markers. Response to corticoid and immunosuppressive therapy was positive.

[Infraorbital bone hemangioma].

Osseus hemangioma is a rare tumor. Its concept and a etiology are not well established. We preset a review and a case of this tumor located in the upper maxilla. Clinical, of this exploration and pathology are studied in this paper. Antigen in factor VIII has been observed. Considerations on different diagnosis are made.
