[Endoscopic and pathological aspect of small bowel and colonic involvement in Whipple's disease: a case report].

We describe a case of Whipple's disease confirmed by clinical, histological, bacteriological and molecular criteria. The duodenal involvement was associated with the presence of an endoscopic and histological enterocolitis. Final diagnosis of small bowel and colonic involvement by Whipple's disease was confirmed by histology and molecular biology.

[Rare pulmonary mycoses in patients with hematologic diseases].

Patients with hematology disease in post-chemotherapy medullary aplasia are susceptible to life-threatening bronchopulmonary mycoses, especially aspergillosis. Other less common pulmonary mycoses are also observed. We report 4 cases due to Penicillium purpurogenum, Acromonium strictum and Scedosporium apiospermum (n = 2) infections.

Study of in vitro drug sensitivity on a newly established cell line from a primary bronchial epidermoid carcinoma of human origin (NSCLCN6).

We studied a cell line established from a primary non-small-cell lung cancer (non-SCLC) of human origin and characterized by midly differentiated epidermoid carcinoma, a human karyotype and keratin expression. Doubling time was about 48 h in vitro and 12 days when transplanted into nude mice. In vitro, this cell line was mainly sensitive to dactinomycin and mitotic poisons such as Vinca alkaloids.

[Borderline lesions of the breast: clinical and radiological study of 20 cases].

We describe the clinical and mammographic signs observed in 20 patients with atypical hyperplasia of the breast. The clinical signs include abnormalities noted at palpation (tumefaction, masses, clusters of nodules) and nipple discharge. The mammographic signs include rounded, clearly delineated opacities with benign appearances, or spiculated masses possibly associated with microcalcifications, stellate opacities, and isolated foci of microcalcifications.
