ABSTRACT
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.

Myxofibrosarcoma frequently recurs locally but rarely metastasizes. Herein, we describe an elderly woman who had myxofibrosarcoma of the right elbow that went untreated during the COVID-19 pandemic. She subsequently presented with two large tumors ulcerating through the skin of her right elbow and left hip.
