    Notizen: Summary Peripheral neuroectodermal tumours (PNET) of bone are rare and mimick those seen in soft tissue (peripheral neuroepithelioma of soft tissue). Their differential diagnosis from Ewing's sarcoma (Es) is extremely difficult by optical means. Here we report 14 new cases of PNET of bone (other than Askin's neoplasm) located primarily in the limbs, pelvic girdle and scapula. Clinically and radiologically they displayed Ewing's sarcoma-like features: mean age was 14.4 years, male/ female ratio being 3:11. Metastasis was present in 6 cases at diagnosis (5 with bone metastasis). Prognosis was poor; thirteen patients died; only one with a metatarsal located tumour is alive and free of disease. The mean survival rate was 25 months following diagnosis and treatment with radio- and multimodal chemotherapy. Histologically the 14 cases displayed Homer-Wright rosettes and pseudorosette-like structures, as well as a fibrillary background and lobular pattern. Immunohistochemistry revealed positivity in a number of neural markers when using paraffin-embedded material: NSE, B-2-microglobuline, HNK-1 (leu-7) and E-36 antibodies. At EM level the cell cytoplasms evidenced dense-core granules with neurosecretion, neurotubules and intermediate filaments like those seen in peripheral neuroepithelioma.

    Asymptomatic encephalic intraparenchymatous neuroepithelial cysts (1984)

    Notizen: Summary The authors report three cases of intraparenchymatous neuroepithelial cysts, which did not communicate with the ventricular system and the subarachnoid space. They were located in (1) the right frontal lobe, (2) the left cerebral peduncle and pons, and (3) the right cerebellar hemisphere. All of them were asymptomatic, despite their volume and location, and presented as incidental autopsy findings. A developmental origin is likely for these non-neoplastic cysts.

    Vascular rupture complicating transluminal angioplasty applied on a failed dialysis vascular access in a patient under chronic steroid therapy (1997)

    Notizen: Abstract. We report a case of venous rupture complicating percutaneous transluminal angioplasty (PTA) applied on a failed dialysis vascular access (VA) in a patient on chronic steroid therapy. This complication resulted in a rapidly growing hematoma which was successfully controlled by a prolonged reinflation of the balloon catheter at the angioplasty site. The absence of oversizing of the balloon catheter and the low inflation pressure at which the perforation occurred suggest a vessel fragility which was probably induced by a long-standing steroid therapy. In dialysis patients in whom steroid therapy does not represent an infrequent therapeutic modality, this potential risk of vascular rupture should be carefully weighted while treating VA stenoses with the use of PTA.

    Notizen: Abstract The clinical and pathological features of 33 previously untreated patients with primary breast sarcoma were retrospectively analysed to evaluate the prognostic significance of histologic variables on survival. The series comprised 17 cystosarcomas phyllodes and 16 stromal sarcomas (excluding angiosarcomas). All tumors were reviewed and classified in similar fashion to extramammary soft tissue sarcomas. In addition, immunohistochemical studies were performed on paraffin sections with a panel of several antibodies directed against cytoskeletal filaments and cellular enzymes; five cases were also examined by electron microscopy. Most tumors were malignant fibrous histiocytoma (21 cases) and fibrosarcoma (6 cases) types. Surgery was the main therapy. Metastasis-free survival rate was significantly correlated only with histological grade, consisting of tumor differentiation, tumor necrosis, and mitotic activity. Courses and survivals of the cystosarcoma and stromal groups were identical, questioning the clinical value of this pathologic distinction. All local recurrence, metastasis, or death occurred within 30 months, though follow-up was much longer. Immunohistochemistry was disappointing for identification of specific histologic sub-types.

    Invasive apocrine carcinoma of the breast: A long term follow-up study of 34 cases (1988)

    Notizen: Abstract We have reviewed the morpho-functional criteria for infiltrating apocrine carcinomas of the breast and analysed long term follow-up of this entity. Thirty-four cases of pure apocrine carcinomas were retrieved from the files of the Dept. of Pathology, IGR, France, for the years 1955–1982. Each case was matched with two controls of other infiltrating ductal carcinomas according to the most important prognostic parameters: nodal status, histograde, anatomic tumor size, and patient age. No significant difference between the survival curves of the two groups was seen. Apocrine carcinoma, although possessing peculiar morphological, ultrastructural, biochemical, and immunohistochemical features to merit recognition as a separate histologic variant of breast cancer, by itself has no apparent clinical significance.
