title: Gigantic thymolipoma.
abstract: A 48-year-old woman with an abnormal shadow in chest radiography during an annual physical examination was found by chest computed tomography to have a large fatty mass lesion found to be diagnosed as a gigantic lipoma. Histopathological diagnosis was found to be benign thymolipoma consisting of mature fatty tissue and hyperplastic thymic tissue structures with Hassall,s corpuscles. Although the diagnosis is supported by imaging studies that demonstrate fat and soft tissue within the tumor, variations occur in computed tomography appearance. We suggest that surgical excision be considered when a gigantic intrathoracic lipomatous mass is in scanning as in this case.
