Coexisting pulmonary nodules in operable lung cancer: prevalence and probability of malignancy.

Introduction: Coexistence of pulmonary nodules in operable non small cell lung cancer (NSCLC) may influence the therapeutic indication. The aim of this study was to evaluate prospectively the prevalence and the probability of malignancy of pulmonary nodules in operable lung cancer.

Methods: From a prospective database, all surgically treated patients diagnosed with NSCLC from 1998 to 2003 were retrospectively reviewed.

Hepatic and pulmonary cystic echinococcosis in a patient from the Central African Republic.

Apical lung opacity was diagnosed in an asymptomatic 30 year-old woman native of Central African Republic by routine chest X-ray. CT scan demonstrated an excavated pulmonary mass and revealed a simple hepatic cyst. Tuberculosis was suspected but mycobacterial cultures remained negative.

Impact of MDCT angiography on the management of patients with hemoptysis.

Objective: The aim of this study was to evaluate the ability of MDCT angiography to modify early results in patients undergoing endovascular embolization for hemoptysis.

Materials And Methods: A comparative study was performed of two consecutive cohorts with 200 patients each who were treated by endovascular embolization for severe hemoptysis; one cohort underwent MDCT angiography and the other did not, but patients underwent further exploration with global aortography. We compared the two groups for patients' age and sex and for the volume, cause, and mechanisms of hemoptysis.

[Very late malignant complications of Hodgkin lymphoma].

Overall survival of patients with Hodgkin lymphoma has dramatically increased in recent years, with an increased rate of malignant complications. We report here a 54-year-old man who presented with concomitant relapse of classical Hodgkin's lymphoma and lung adenocarcinoma 20 years after initial treatment with chemotherapy and mantle radiotherapy. Pathogenic mechanisms of these malignant complications are discussed.

[Oral erosive lichen planus associated with Good syndrome].

Introduction: Good syndrome is characterized by thymoma, hypogammaglobulinemia, low number of peripheral B cells, and variably, peripheral CD4 T cell lymphopenia and inverted CD4/CD8 T cell ratio, associated with infections and autoimmune diseases.

Case Report: We report an 85-year-old woman who presented with oral erosive lichen planus and thymic tumor. Improvement of oral erosive lichen planus was observed after resection of a benign thymoma, but was ineffective on the immunodeficiency syndrome.
