RESUMEN
An interventional pulmonologist possesses expertise in minimally invasive diagnostic and therapeutic procedures involving the airways, lungs and pleura. A malignant pleural effusion (MPE), which occurs in 20% of cancer patients, can be a daunting diagnostic challenge insofar as the pleural cavity is a closed cavity. In these patients, treatment may consequently be delayed before a precise diagnosis can be given. In the meantime, an interventional pulmonologist is called upon to carry out a wide range of examinations in order to establish the etiological diagnosis and to treat the symptoms of an MPE patient. Classical medical thoracoscopy, also called "pleuroscopy", is the reference method in MPE diagnosis because it allows visualization of the pleural cavity, pleural biopsy under direct visual control, providing excellent diagnostic yield. Over the past decade, new diagnostic methods have emerged, such as ultrasound-guided biopsy, as well as different interventions, such as indwelling pleural catheters, aimed at improving the quality of life of MPE patients, for whom therapeutic options are limited. The objective of this review of the literature is to point out the role of the interventional pulmonologist in the management of MPE by detailing the various diagnostic and therapeutic methods he possesses at the present time.

There have been a number of reports on cervical carcinomas, both invasive and intraepithelial (CIN III), indicating the presence of intracellular mucins in the absence of glandular differentiation. Yet, the expression of such cells in the normal/original squamous epithelium of the cervix remains unexplored. We investigated the presence of mucin-distended goblet cells at this site, after examining retrospectively normal cervices from 250 hysterectomy specimens. Goblet cells were detected in 3.2% (8/250) of the cervices examined using haematoxylin and eosin stained sections and confirmed by mucin histochemistry: alcian blue (AB) pH 2.5, periodic acid-Schiff reaction with and without diastase digestion (PAS-d, PAS) and the combined AB/PAS. Additional sections were stained with Diazo and Masson-Fontana for argentaffin granules and Grimelius for argyrophil cells, but were all negative and no other cell types were identified. It is believed that this incomplete type of intestinal metaplasia is an acquired change in the cervix, derived from multi-potential stem cells of Müllerian duct origin.

Myxoid leiomyosarcoma is an extremely rare variant of leiomyosarcoma, masquerading almost to perfection as a benign lesion. For, indeed, the tumor lacks the defining features of high mitotic activity, cellular atypia or necrosis, and the microscopic picture is dominated by abundant myxoid stroma containing sparse spindle cells. We report here such a case occurring in the uterus and discuss the differential diagnosis. The relevant literature is reviewed.
