The authors present a case report of a giant Müllerian duct cyst in the perineum. A 37-year-old man presented with a mass with the size of 50 cm×40 cm×30 cm in the perineum. Computed tomography (CT) scan and magnetic resonance imaging (MRI) of the pelvis and perineum found a huge multilocular cystic mass. X-ray film of the pelvis showed a giant soft-tissue shadow of high density in the perineum. Voiding cystourethrogram did not show any cyst interlinked to posterior urethra. After related examinations, the patient underwent open surgical resection of the cyst. Pathologic examination confirmed the presence of a Müllerian duct cyst. Huge Müllerian duct cyst is uncommon in clinic. Treatments of Müllerian duct cysts depend on their sizes and symptoms.

Diffuse cystic lung diseases are uncommon but can present a diagnostic challenge because increasing number of diseases have been associated with this presentation. Cyst in the lung is defined as a round parenchymal lucency with a well-defined thin wall (<2 mm thickness). Focal or multifocal cystic lesions include blebs, bullae, pneumatoceles, congenital cystic lesions, traumatic lesions, and several infectious processes such as coccidioidomycosis, Pneumocystis jiroveci pneumonia, and hydatid disease. “Diffuse” distribution in the lung implies involvement of all lobes. Diffuse lung involvement with cystic lesions can be seen in pulmonary lymphangioleiomyomatosis, pulmonary Langerhans’ cell histiocytosis, lymphoid interstitial pneumonia, Birt-Hogg-Dubé syndrome, amyloidosis, light chain deposition disease, honeycomb lung associated with advanced fibrosis, and several other rare causes including metastatic disease. High-resolution computed tomography of the chest helps define morphologic features of the lung lesions as well as their distribution and associated features such as intrathoracic lymphadenopathy. Correlating the tempo of the disease process and clinical context with chest imaging findings serve as important clues to defining the underlying nature of the cystic lung disease and guide diagnostic evaluation as well as management.

大豆胞囊线虫（SCN，Heterodera glycines）是危害全球大豆生产最严重的线虫。作物轮作和培育抗线虫品种是防治线虫的主要方法。随着越来越多能够克服常用抗源的毒性SCN 群体出现，有必要寻找更多新的抗源或拓宽抗性遗传背景。本文综述了大豆抗SCN 基因的研究进展，以及这些基因如何相互作用，从而使大豆能够抗SCN。本文还提供了最新分子作图和分子标记，可用于不同抗性品系和品种的大规模选择和鉴定，以加速常规育种计划。深入了解SCN 寄生蛋白和大豆对病原体的抗性是通过基因修饰、基因叠加、回交或基因工程引入新的抗源而使抗源多样化的关键。
