It is usually predominant in males. Local recurrences are common (44%-78%) and distant metastases may occur years after the initial presentation. The reported rates of metastases range from 10% to 48%, which are usually accompanied by a sacrococcygeal chordoma. Cases of surgical seeding and intradural spinal seeding also have been reported climcally. To our knowledge, the present case is the first one concerning cerebrospinal fluid metastases and fatal progression of a sacrococcygeal chordoma.展开更多

DPL occurs mostly in children and young adults and often undergoes a progressive clinical course, eventually causing deterioration of the lung. Both the clinical diagnosis and treatment of DPL remain a challenge. Here, we report a case of DPL in a 53-year-old Chinese woman with comprehensive investigations including pulmonary function tests, computer tomography (CT), bronchoscopy and histological examination of the lung biopsy, and review the literature.展开更多

The lymphatic vessels that contribute to the pulmonary lymphatic circulation originate in the subpleural connective tissue, not directly from the visceral mesothelium. Therefore, according to the current point of view, pleural effusion absorption through the visceral pleural is normally neclligible and visceral pleura,展开更多
