Histological lesions in the testis of infertile men with varicocele.

Varicocele frequently causes male infertility and histological lesions at the contralateral testis. The most frequent lesions found in this study included maturation arrest in the spermatidic phase, cellular and acellular thickening of the tubular wall, and degeneration of the Leydig cells. These lesions were typical of varicocele and their simultaneous presence suggests that scrotal temperature and modified endocrine secretion of the interstitial testis play a role in the pathogenesis of this type of infertility.

Histiocytosis 'X' of the central nervous system. Clinical and pathological report of a case with predominant cerebellar involvement.

The case is presented of a child with early manifestations of Hand-Schüller-Christian disease limited to exophthalmos, and rapid final progression towards a clinical picture dominated by intracranial hypertension and cerebellar involvement, caused by massive histiocytic infiltration of the cerebellum, combined with discrete subdural deposits of xanthomatous tissue and minor deposits in other parts of the central nervous system and other organs.

Ocular involvement in recurrent cyst of Rathke's cleft: Case report.

Cysts of Rathke's cleft are considered as benign lesions, a practically permanent cure of which can be achieved by aspiration of the fluid content and ample opening of the capsule. The case of a patient who suffered from a recurrence of the cyst, 13 years after a first operation carried out according to such surgical criteria, is reported in order to signal the actual possibility of recurrence of such lesions.

Cystic suprasellar and retrosellar arachnoiditis: a clinical and pathologic follow-up case report.

A patient, previously operated upon for a supra-and retrosellar arachnoid cyst, had again to undergo surgery for a recurrence and died in the early postoperative course. The gross and microscopic pathologic evidence obtained through necropsy is described: it seems to confirm the inflammatory nature of the arachnoid cyst, thus legitimating the term cystic optochiasmatic arachnoiditis used for the description of the same case in a previous report.

Histological and ultrastructural study of intracranial saccular aneurysmal wall.

The material studied consists of 10 cases of intracranial saccular aneurysms. Four came from autopsies, and in each of the other six aneurysmal wall was obtained at surgery after clipping of the aneurysm. The most significant findings from this pathological study are the almost complete disappearance of the internal elastic lamina at the level of the aneurysmal neck, sclerosis of the muscle coat, and in satellite vessels and vasa vasorum disruption of the internal elastic lamina and partial luminal occlusion. The importance of ischaemic changes in the aneurysmal wall is discussed. Rupture of the aneurysm at the distal extremity of the sac depends probably on the progressive brittleness of its wall which becomes sclerotic and less resistant to the blood pressure within. Splitting or rupture of the aneurysm appears to be dependent on degenerative ischaemic alterations in its wall.

Dysrhythmias and sudden death in acromegalic heart disease. A clinicopathologic study.

A clinicopathologic investigation was carried out in a patient with acromegaly from acidophylic adenoma of the hypophysis. Pronounced cardiomegaly and disturbances in impulse formation and conduction led to sudden death. The problem of acromegalic cardiomyopathy has been reviewed. Particular attention has been focused on the histopathologic findings in the working and specific myocardium, and in the intrinsic nervous supply to the sinoatrial node, which were correlated with the electrocardiographic features of atrioventricular conduction delay and sick sinus syndrome.

Sudanophilic leucodystrophy: report of a case with tigroid demyelination of the centrum ovale.

A 17-year-old girl with negative familial and personal history developed a progressive neurologic disorder characterized by cortical amaurosis, metal deterioration and spastic tetraparesis. Death occurred one year after the onset of symptoms. Histopathologic examination of the C.N.S. showed the presence of extensive, discontinuous demyelination of the white matter of the centrum ovale, with preservation of perivascular myelin islets, associated with massive fat degradation, loss of axons and severe astroglial proliferation. This case belongs to the group of sudanophilic leucodystrophies, being an atypical case, a transition between pure sudanophilic leucodystrophy and the group of Pelizaeus-Merzbacher's disease.
