Consider rare tumors in atypical pulmonary artery masses; extends the known mimics of angiomatoid fibrous histiocytoma.
A young man presented to the emergency department with pleuritic chest pain and shortness of breath. Of note, he recently went on a long-distance flight of about 9 hours. Given his recent long-distance travel and clinical symptoms, a pulmonary embolism was suspected. However, pathological examination of the excised pulmonary artery intraluminal mass demonstrated an angiomatoid fibrous histiocytoma. This case describes the clinicopathological and immunohistochemical features and molecular profile of a rare type of pulmonary artery tumour, a pulmonary artery angiomatoid fibrous histiocytoma.
