At the intersection of primary pulmonary myxoid sarcoma and pulmonary angiomatoid fibrous histiocytoma: Observations from three new cases

摘要

Sir: Twin recent reports identified a novel entity, primary pulmonary myxoid sarcoma (PPMS) and an endobronchial presentation of angiomatoid fibrous histiocytoma (AFH). PPMS were described as 20-40-mm diameter endobronchial, lobulated neoplasms occurring in young patients (mean age 45 years), and comprising polygonal to spindled cells within a myxoid stroma evocative of extraskeletal myxoid chondrosarcoma (EMC).
