Adenosquamous Carcinoma of the Lung and Its Radiologic Features

肺腺鱗細胞癌比其它的肺支氣管癌預後差，在診斷時往往已轉移了。它們的放射線特徵很少被發表，且形成原因尚無定論。因此我們探討32例肺腺鱗細胞癌的放射線特徵和其形成原因，並描述它們的放射線表現，來尋求是否有放射線特徵可與其它的肺支氣管癌做鑑別診斷。 32例的肺腺麟細胞癌的臨床和放射線特徵被覆審。所有病例都有胸部放射線攝影片和電腦斷層可供參考。腫瘤並以位置，型狀，和TNM分級來定。在胸部放射線攝影片和電腦斷層中，腫瘤直徑經測量為1.8-8.0公分（中數，4.3公分）。26個腫瘤是固體的，6個是有空洞的。25個是在中心肺門的，7個是在肺周邊的。13個腫瘤邊緣是輕度不規則和細刺的（型式3），19個腫瘤是腫瘤邊緣重度不規則和細刺的（型式4）。肺腺鱗細胞癌的放射線特徵是一個呈現各種形態的腫瘤，大多數是在周邊單獨的小節結或是較少數為在中心肺門的團塊。腫瘤有固體的，有空洞的。腫瘤邊緣主要是由輕度或重度不規則和細刺的邊緣所構成。

Adenosquamous carcinoma, a carcinoma which shows both squamous carcinomatous and adenocarcinomatous components, is a form of bronchogenic carcinoma with the radiologic features rarely reported and the cause of its formation remains unconvincing. Therefore, we studied the radiologic appearance of this tumor to describe its findings to discern if there are features that distinguish it from other bronchogenic carcinomas and the cause of its formation. Clinical and radiologic features of 32 cases of adenosquamous carcinoma were reviewed. Chest radiographs and CT scans were available in all cases. The tumors measured 1.8-8.0 cm in diameter (median, 4.3 cm) on CT scans or chest radiographs. Twenty-six tumors were solid and 6 were cavitary. Seven tumors were central and 25 were peripheral. Thirteen tumors had margins with some irregular undulations or slight spiculation (type Ⅲ) and 19 had spiculated, grossly irregular margins (type Ⅳ). Results of fine-needle aspiration of 21 tumors showed malignant tumors in 14 cases, but adenosquamous carcinoma in only 1. The appearance of adenosquamous CA on CT and chest radiographs is not characteristic. Its radiologic findings are a spectrum, typical presenting as a peripheral solitary nodule or less commonly a central hilar mass with grossly irregular, slightly spiculated distributed margins.
