Biphasic Malignant Pleural Mesothelioma Masquerading as a Primary Skeletal Tumor

Biphasic malignant pleural mesothelioma is a rare malignant tumor, usually presenting as a pleural-based mass in a patient with history of chronic asbestos exposure. We herein report a case of a 41-year-old man who presented with chest pain and had a chest computed tomography (CT) scan suggestive of a primary skeletal tumor originating from the ribs (chondrosarcoma or osteosarcoma), with no history of asbestos exposure. CT-guided core needle biopsies were diagnosed as malignant sarcomatoid mesothelioma. Surgical resection and chest wall reconstruction were performed, confirming the diagnosis and revealing a secondary histologic component (epithelioid), supporting the diagnosis of biphasic malignant mesothelioma.

Asphyxiation Caused by Giant Fibrovascular Polyp of the Esophagus

Giant fibrovascular polyps of the esophagus are rare, benign, “tumorlike” lesions that typically present as large pedunculated growths arising in the cervical esophagus. The predominant histologic component of these lesions is variable, often resulting in misdiagnosis. Clinically, these polyps present with nonspecific symptoms and are often undiagnosed or misdiagnosed until they are significant in size. Diagnosis is best made by upper endoscopic evaluation; surgical excision is the definitive treatment. Although rare, asphyxia resulting from obstruction of the glottis is the most serious complication. We describe a case of asphyxiation caused by laryngeal occlusion by a giant esophageal polyp and we provide a review of the literature.
