Nephrogenic Bladder Adenoma: A Case Report

Nephrogenic adenoma is a rare epithelial urothelial metaplasia, occurring frequently in males in the 4th decade of life. We report a case of nephrogenic bladder adenoma occurring in a pre-puberal patient; to date only 19 other cases of nephrogenic adenoma occurring at pre-puberal age have been described. After endoscopic resection, the patient received an early single endoluminal dose of epirubicin, suspecting a urothelial carcinoma; after 7 years no relapses have occurred.

Survival following treatment of a cardiac malignant fibrous histiocytoma

The authors report the successful surgical and chemotherapeutic management of a malignant fibrous histiocytoma with localization in the heart. This rare malignancy has specific morphologic characteristics and is diagnosed in adults when it is already locally aggressive or metastasized. The average survival time for patients with malignant fibrous histiocytoma is < 12 months. Neither clinical nor instrumental signs of recurrence have been detected in this patient after an aggressive surgical resection and a specific therapeutic approach.

Non-Hodgkin lymphoma in a gynecologic service. A report of three cases

Primary lymphoma arising in female genital tract organs is extremely rare. We report three cases of non-Hodgkin lymphoma which were encountered during a four-year period at our gynecologic department. One patient presented with an inguinal mass; another had a primary lymphoma of the vagina and the third had massive pelvic and para-aortic lymphomatous involvement. The gynecologists should be aware that, although rarely, lymphomas may arise in the genital tract, and that a massive involvement of inguinal, pelvic or para-aortic nodes may be related to a lymphoproliferative disease.

[Fetal uropathies: anatomo-pathologic background]

The kidney malformations are complex anatomo-clinical entities that can be described with different classification approaches, based on morphological or etiopathogenetic criteria. The most serious fetal uropathies can be associated with the oligohydramnios sequence, due to insufficient urine escretion, related, for example to bilateral renal agenesis. A second malformation sequence can also be present, the so-called prune belly syndrome, in which an early urethral obstruction can produce abnormal bladder distension and finally renal dysplasia and globous dilation of the abdomen. The anatomo-pathological experience of the last ten years in the Institute of Pathological Anatomy of the University of Bari is based upon 154 cases of congenital uropathies in second trimester fetuses. Almost 80% of these cases presented also other associated anomalies, both chromosomal and non chromosomal syndromic or in casual combination. The possible echographic recognition of these pathologies, together with genetic and anatomopathological studies allow to categorize the fetal uropathies in two groups: the first characterized by an early or late obstruction of the urinary tract, in "sensu strictu" the true obstructive uropathies, and the second, formed by different morphologies all genetically determined.

Recurring intracranial meningiomas. Morphometrical evaluation of nuclear pleomorphism by S.A.M. (shape analytical morphometry) system

Meningiomas are the most common neoplasms of the central nervous system and their biological behavior is not always predictable from the histologic appearance of the tumors. The nuclear pleomorphism seems to be one of the most important morphological features in the prediction of recurrence. By using analytical morphometric methods it is possible to quantify nuclear atypias and to obtain parameters describing nuclear contour irregularities and distortions of the figure. Moreover the amount of information obtained from analytical procedure allowed to discriminate, by multivariate discriminant analysis recurrent or no-recurrent meningiomas (5% of error).
