Diagnostic and therapeutic approach to endobronchial metastases from extra-thoracic neoplasms: A report of three cases and brief review of literature.

Introduction: Endobronchial metastases (EBMs) are rare, with primary tumours predominantly of breast, renal, and colorectal origin. Bronchoscopy is the diagnostic gold standard, with histological confirmation through immunohistochemical study.

Cases: We presented three cases of EBMs, one secondary to colorectal cancer and two associated with renal tumours.

Gastric foveolar adenoma in the duodenal bulb: case report.

Foveolar-type adenomas are very rare lesions, representing approximately 2.7% of duodenal adenomas with gastric phenotype, histologically characterized by tall columnar cells resembling gastric foveolar epithelium and a tubulovillous structure with various degrees of dysplasia. Their risk of progression to adenocarcinoma is related to the size of the polyp and the presence of high-grade dysplasia.

Helicobacter pylori infection is the most common infectious disease worldwide. It is associated with duodenal and gastric ulcer disease and the risk of gastric neoplasia. The management of helicobacter pylori infection currently represents a real challenge for clinicians, given the ever-increasing rate of resistance of Helicobacter pyolori to various antibiotics.

A rare coexistence of sarcoidosis with overlap syndrome and sarcoidosis with primary biliary cholangitis and Sjogren's syndrome: Two distinct case reports.

Sarcoidosis and the overlap syndrome of autoimmune hepatitis and primary biliary cholangitis (PBC) share common clinical, biological, and histological features. The simultaneous occurrence of these diseases have been reported in few cases and suggests that a common pathway which may contribute to granuloma formation in both conditions. We report the cases of two female patients having an association of sarcoidosis and inflammatory liver diseases.

Eosinophilic enterocolitis: a case report.
