Primary Carcinoid Tumor of the Parietal Pleura-Case Report

類癌是神經內分泌腫瘤，大多數的類癌發生於腸胃道及呼吸道。它們被認為是良性的並且增長緩慢的，但也有相當比例的患者是惡性的（轉移至肝臟，骨骼，皮膚等器官）。原發性支氣管肺類癌約占已切除的肺癌的1% to 5%；約占所有類癌的25%。最常被報告的支氣管肺類癌的位置是支氣管。只有極少數的原發性肋膜類癌被報告過。我們提出一個極為罕見的原發性肋膜類癌案例發生在一個24歲的男子。他意外發現有一個腫塊位於右側肋膜，並經胸腔鏡進行腫瘤切除。組織學檢查，包括免疫染色檢查診斷為典型的原發性肋膜類癌。並沒有證據表明肋膜外浸潤或遠處轉移。隨後給予術後輔助放射治療。在隨後的追蹤到目前為止，他並沒有證據表示有局部復發或轉移。

Carcinoids are neuroendocrine tumors that primarily affect the gastrointestinal tract, lungs, and bronchi. They are considered benign with slow growth, but can be malignant in a substantial percentage of patients (metastasizing to the liver, bones, skin, etc). Primary bronchopulmonary carcinoids constitute 1% to 5% of resected lung cancers and about 25% of all carcinoids. The most commonly reported location for pulmonary carcinoid tumors is the major bronchi. There are very few reports of primary pleural carcinoids. We present an extremely rare case of primary pleural carcinoid tumor in a 24-year-old male. He was found incidentally to have a right pleural mass and underwent thoracoscopy with pleural tumor excision. Histological immunohistochemical analysis confirmed the diagnosis of typical carcinoid tumor in the pleura without extrapleural invasion or distant metastasis. The patient received local radiotherapy as adjuvant treatment after surgical intervention. To date, the patient has not exhibited evidence of local recurrence or metastasis.
