The majority of cases are accidentally diagnosed by imaging studies done for other reasons, so they are often diagnosed in the later stages. Due to the rarity of both neoplasms, the synchronous presentation and the lack of effective therapeutic options; we report a case concerning about a female patient with adrenal cancer with a low grade solitary fibrous tumor who underwent surgery, adjuvant radiotherapy and chemotherapy with good response.展开更多

Recently,several reports have suggested that IMT is a true neoplasm rather than a reactive lesion. By definition, it is composed of spindle cells （myofibroblasts） with variable inflammatory component, hence the name is IMT. We report a patient of inflammatory myofibroblastic tumor in lung with osteopulmonary arthropathy.展开更多
