Acinic cell adenocarcinoma of the parotid gland: case-report.

We report a case of acinic cell adenocarcinoma of the parotid in a 18-year-old young man. Clinical examination showed a firm mobile mass of the gland. Light microscopy revealed the tumor composed of two distinct cell populations: a main one with large, polyhedrical or round cells with eosinophilic cytoplasm and a smaller proportion of granular cytoplasm clear cells.

Fine needle aspiration cytology of invasive micropapillary (pseudopapillary) carcinoma of the breast. Report of 11 cases with clinicopathologic findings.

Objective: To describe the cytologic features of invasive micropapillary carcinoma of the breast, a distinct, unusual variant of infiltrating duct carcinoma characterized histologically by pseudopapillary structures lacking fibrovascular cores and tubuloalveolar structures floating freely within clear spaces separated by a delicate fibrocollagenous stroma and characterized clinically by prominent lymphotropism and an aggressive clinical course.

Study Design: We reviewed the clinical, cytologic, histologic, immunohistochemical and flow cytometric features in 11 cases of invasive micropapillary carcinoma of the breast diagnosed preoperatively by fine needle aspiration.

Results: All patients were women, ranging in age from 31 to 83 years.

[Mesothelial cyst of the diaphragm. Presentation of an unusual case].

The authors report a case of mesothelial cyst of the diaphragm in a boy 11 years old who was examined for pain in the right hypochondrium with exacerbation during respiratory movements. Ultrasonography and CT suggested the diagnosis. However the final diagnosis of mesothelial cyst of the diaphragm was possible only after laparotomy and histological examination.

[Chronic idiopathic intestinal pseudo-obstruction: a clinical case and review of the literature].

The authors report a case characterized by impairment of the intestinal function clinically mimicking a mechanical obstruction in the absence of any occluding lesion of the gut lumen. Different pathological conditions, different clinical syndromes, instrumental approach for the diagnosis as well as medical and surgical treatment of pseudo-obstruction are discussed. Surgery has not been proven to be effective in the clinical management of CIIP for the irreversibility of the myopathic or neuropathic lesions.

[Secondary bacterial peritonitis: a diagnostic and therapeutic update].

In spite of the availability of new powerful antibiotics, intraabdominal sepsis still has a high mortality rate (20-50%). With regards to postoperative peritonitis, the referred high mortality rate is due to a late recognition and a consequently late treatment. The causes for late diagnosis are: uncertain clinical picture; misuse of analgesic drugs; reluctance of the surgeon to accept a failure.

[Soft-tissue malignant melanoma (clear-cell sarcoma). Description of 2 cases with unusual histological features].

Malignant melanoma of soft part. Report of two cases with unusual histological features. Two examples of malignant melanoma of soft parts (clear cell sarcoma) are reported.

Fibromatosis of the larynx in the adult.

We describe the fourth case of aggressive fibromatosis of the larynx arising in an adult. Most cases of laryngeal fibromatosis have been described in children. In the larynx it may behave the same as in other sites, with local aggressiveness but without metastasis.

Verruciform xanthoma of the vulva: case report.

A rare case of verruciform xanthoma of the vulva is reported. Diagnosis was made possible by histopathological examination and immunohistochemical staining. Verruciform xanthomas generally occur in the oral cavity.

Hyperthyroidism due to a thyroid-stimulating hormone (TSH)-secreting pituitary adenoma associated with functional hyperprolactinaemia. A case report.

This paper reports the case of a 31-year-old woman with hyperthyroidism, increased TSH and thyroid hormone levels, evidence of a pituitary adenoma, hyperprolactinaemia, amenorrhoea, and galactorrhoea. Following trans-sphenoidal pituitary adenomectomy, mild hyperthyroidism and increased TSH and alpha subunit levels persisted, whereas hyperprolactinaemia, amenorrhoea, and galactorrhoea disappeared. Serum TSH levels were not affected by administration of TRH, metochlopramide, domperidone, l-dopa or somatostatin.

An unusual case of primary hormone-secreting germ cell tumor of the retroperitoneum.

An unusual case of primary retroperitoneal germ cell tumor is presented. Criteria for considering such a diagnosis in patients with apparent poorly differentiated carcinomas are discussed. An interesting hypothesis is presented to explain the hormonal abnormalities observed.

Xanthogranulomatous pyelonephritis in childhood: report on an unusual case.

A case of localised xanthogranulomatous pyelonephritis (XPN) in a 4-year-old female with an unusual radiological picture is reported. The young girl was suspected to have a liver tumour because of a hypervascularised area found by arteriography in the hepato-diaphragmatic region. Laparotomy disclosed a large mass in the upper pole of the right kidney which was adherent to the liver and to the diaphragm.

Carcinoma of the breast with osteoclast-like giant cells. Fine-needle aspiration cytology, histology and electron microscopy of 5 cases.

Five cases of a rare peculiar type of mammary carcinoma with osteoclast-like stromal giant cells are reported. The tumors are characterized by a large number of multinucleated giant cells in intimate association with the epithelial neoplastic cells. The light and electron microscopic observations confirm the earlier reports about the origin of the giant cells from mononuclear histiocytes as a local response to some tumoral products.

Ewing's sarcoma arising primarily in the spinal epidural space: fifth case report.

Ewing's sarcoma is found exceptionally as a primary epidural tumor of the spine. Four cases have been described in the literature. We describe the fifth case: a 10-year-old boy who underwent operation followed by radiotherapy and chemotherapy.

[Clinico-diagnostic considerations on lymphocytic thyroiditis. Presentation of clinical cases].

Personal experience with autoimmune lymphocyte thyroiditis, represented by 11 cases observed between 1972 and today, is reported. After some brief aetiopathogenetic notes on the lesions in question, the problems of diagnosing the nature of the thyropathy are stressed. After reviewing the examinations that have been proposed in the literature, it is noted that the preoperative recognition of a thyroiditis with autoimmune genesis is still problematical.
