The association between Henoch-Schönlein syndrome and renal amyloidosis: a proposal of a pathogenic mechanism.

The clinicopathological analysis of 250 pediatric cases that had been tissue-diagnosed with renal amyloidosis revealed three patients associated with Henoch-Schönlein syndrome (HSS). The renal biopsies revealed AA-type amyloidosis in all three cases. Case 2 displayed focal and segmental proliferative glomerulonephritis in the same renal biopsy.

Hemolytic-uremic syndrome (HUS): a clinicopathological study of 15 cases.

Although hemolytic-uremic syndrome (HUS) is a clinico-pathological entity, renal biopsies are usually not indicated for diagnosis, and therefore, studies concerning the histological aspects of the syndrome are few. This study mainly describes the morphological characteristics of 15 tissue-diagnosed sporadic cases of HUS. The ages of the patients ranged between 10 mos.

Optic glioma of childhood: clinical, histopathological, and histochemical observations.

This report documents the long-term clinical and histopathological behaviour of eight intraorbital and 16 intracranial optic nerve gliomas and relates the therapeutic data to the prognosis for both visual acuity and survival. The mean age at onset of symptoms was 8.6 years and at the diagnosis 10.

Post-irradiation osteosarcoma of the iliac bone: a case report.

A case of osteosarcoma of the iliac bone developing 12 years after the successful management of childhood rhabdomyosarcoma is presented. The frequency of secondary tumors, mainly bone malignancies, following therapeutic irradiation in the pediatric age-group, and the criteria for the diagnosis of radiation-induced bone sarcoma are discussed.
