RESUMEN
All adenomas of the major duodenal papilla (MDP) require resection regardless of morphological structure due to high risk of malignancy. Currently, intraluminal endoscopic interventions are preferable for these adenomas. MDP neoplasms with intraductal spread (type III and IV) are of particular difficulty for endoscopic techniques. Intraductal radiofrequency ablation provides new opportunities for minimally invasive treatment of patients with MDP adenomas and intraductal component. A 72-year-old patient after previous endoscopic papillectomy for MDP adenoma admitted to the Vishnevsky National Research Medical Center of Surgery due to residual adenomatous growths within the papillectomy zone extending to the common bile duct throughout 13 mm. The patient underwent intraductal RFA under endosonography and cholangioscopy. Despite difficult localization of residual growths extending to the common bile duct, endosonography-guided intraductal RFA provided total destruction of residual tumor that was confirmed by cholangioscopy. Length of treatment was 4 months, relapse-free period - 10 months. Minimally invasive endoscopic technology for residual MDP adenoma provided good clinical results.

Castleman disease (CD) is a benign lymphoproliferative disease. Small prevalence and diverse clinical course of disease makes it difficult to standardize diagnostics and treatment. Currently, the number of CD patients has increased with improvement in the quality of examination. Therefore, differential diagnosis of this disease is important. We present a young patient with CD and retroperitoneal non-organ neoplasm. Despite a thorough preoperative examination, the final diagnosis was established only after histological examination of surgical specimen. We discuss the diagnosis and surgical treatment of a patient with unicentric type of CD.
