[AL amyloidosis].

AL amyloidosis is a systemic disease caused by the deposition of fibrillar proteins in organs and tissues. These deposits are responsible for organic dysfunctions and may be rapidly lethal. Current therapy is unsatisfactory.

Nuclear DNA content, proliferation index and nuclear size determination in normal and tumoral adrenal tissues, pheochromocytomas and metastases.

The diagnostic values of nuclear size, proliferation index and ploidy level were investigated in a series of 58 samples from adrenal glands, including 9 samples from normal adrenal glands, 18 adenomas, 3 carcinomas, 16 pheochromocytomas and 12 metastases. Nuclear assessments were computed on Feulgen-stained nuclei by means of a cell image processor. Ploidy level was assessed by means of both the DNA index and DNA histogram type.

Carcinomas of the thyroid with unusual presentation. About two cases.

Two cases of thyroid carcinoma with unusual presentation are reported. In the first case, a follicular carcinoma was associated with hyperthyroidism from a hot nodule located in the same lobe. This condition is not so infrequent as indicated by the literature and should warrant pathological examination at the time of excision of the hot nodule.

DNA histogram typing in human seminomas.

Characterization of the nuclear DNA content (DNA index and DNA histogram type) was carried out in 9 normal testicular tissues and 21 seminomas. Proliferative activity was further determined in the seminomas. Nuclear DNA content was assessed by means of a cell image processor computing the integrated optical density on Feulgen-stained nuclei from formalin-fixed paraffin-embedded materials.

Cyst of the gallbladder.

A cyst of the gallbladder is a very rare lesion. The possible causes of such an anomaly are reviewed. It may be acquired or congenital.

[Value of echography and fine needle biopsy for diagnosis of thyroid nodules].

Value of ultrasonography and fine needle biopsy for the diagnosis of thyroid nodules. From 1/1/1986 to 31/7/1987, thirty patients with a nodular disease of the thyroid (14 solitary nodules, 9 multiple nodules, 5 colloid cysts, 2 carcinomas) were included in a controlled prospective study using clinical examination, scintigraphy, sonography and fine needle biopsy of the gland. All the patients were operated on and the specimens were submitted to pathological examination.

Intra-abdominal cystic lymphangioma in a newborn infant. Case report and review of the literature.

We report a newborn infant presenting with an intra-abdominal cystic lymphangioma, in which necrosis and infection led to an unusual combination of solid and liquid areas observed by ultrasonography.

Prenatal diagnosis of a pulmonary cyst by ultrasonography.

We report a patient in whom a prenatal diagnosis of an intrapulmonary cyst was made by ultrasonography. To our knowledge, no such case has been reported before and prenatal diagnosis permitted prompt management of an asymptomatic neonate.

[A case of mesenteric venous thrombosis. Review of the literature].

A case is presented in which a venous mesenteric thrombosis necessitated an extended small bowel resection. The postoperative follow-up with its complications is presented. Review of the literature.

Chronic neutrophilic leukaemia with enlarged lymph nodes and lysozyme deficiency.

A further case of chronic neutrophilic leukaemia is reported and compared to fourteen previously reported cases. The presence of enlarged lymph nodes as the first clinical sign and the existence of a relative lysozyme deficiency of the granulocytes were striking features.

Treatment with steroids of a giant cell granuloma of the maxilla.

This case report of giant cell granuloma involving the maxilla is of particular interest for two reasons: the locally aggressive clinical course contrasting with the diagnosis of a benign disease and the spectacular, although transient, response under steroid treatment. Corticotherapy should be further tested in cases of invasive or recurring giant cell granuloma.

A case of familial visceral myopathy with atrophy and fibrosis of the longitudinal muscle layer of the entire small bowel.

The case of a 21-yr-old man, who died in cachexia after 2 yr of intermittent abdominal pain, bouts of diarrhea, and anorexia, is reported. Laboratory tests performed shortly before death disclosed signs of malabsorption. Radiologic examination of the gastrointestinal tract showed a coarse mucosal relief in the upper jejunum and a tubular aspect in the rest of the small bowel.
