ALK+ Anaplastic large cell lymphoma with extensive cardiac involvement: A rare case report and review of the literature.

Cardiac lymphoma is a rare entity. In this setting, the secondary involvement of the heart is far more frequent than the primary cardiac lymphoma. Herein, we present an autopsy case of a disseminated anaplastic lymphoma kinase (ALK)-positive anaplastic large cell lymphoma with a dominant mediastinal involvement. Extensive cardiac infiltration with the near replacement of the myocardial wall by the neoplastic cells was observed. A total of nine isolated case reports of anaplastic large cell lymphoma with cardiac involvement were found in the English-language literature, and a widespread cardiac and thymic infiltration by the systemic ALK-positive anaplastic large cell lymphoma has not been documented. An incidental regenerative nodule was also identified in the liver. The patient died of pulmonary thromboembolism and cardiac arrest.

Stents for benign and malignant esophageal strictures.

This paper presents commentaries on endotherapy for esophageal perforation/leaks; treatment of esophageal perforation; whether esophageal stents should be used for treating benign esophageal strictures; what determines the optimal stenting period in benign esophageal strictures/leaks; how to choose an esophageal stent; how a new fistula secondary to an esophageal stent should be treated; which strategy should be adopted when a fistula of a cervical anastomosis occurs; intralesional steroids for refractory esophageal strictures; balloon and bougie dilators for esophageal strictures and predictors of response to dilation; whether refractory strictures from different etiologies respond differently to endotherapy; surgical therapy of benign esophageal strictures; and whether stenoses following severe esophageal burns should be treated by esophageal resection or esophageal bypass.

Undifferentiated embryonal sarcoma of liver in an adult masquerading as complicated hydatid cyst.

Benign or malignant hepatic lesions may rarely mimic inflammatory lesions on imaging. We describe a case of young adult male presenting with pain abdomen and fever of short duration. Imaging revealed large complex multiseptated lesion in the right lobe of liver. Complicated hydatid cyst was kept as first differential diagnosis depending on clinic-radiologic findings. However, due to few atypical imaging features, FNAC of the lesion was performed which confirmed the lesion as UESL.
