Angiomatoid fibrous histiocytoma (AFH) is a very rare soft tissue tumor with undetermined malignancy potential most commonly occurring in children, adolescents, and young adults. AFH usually affects extremities in areas of lymphoid tissue such as popliteal fossa, decubital fossa or neck, however very few cases involving lung, mediastinum, ovary, retroperitoneum and vulva are also reported (3). Here we present a rare case of AFH of endobronchial origin concealing EWSR1 rearrangement and CD163 positive.
