He reported pain in the lower left limb, which was not relieved throughout the day and was exacerbated by physical movements and efforts. In addition, there was an increase in volume in the middle anterior region of the chest, approximately 15 cm long, hard, painful, with regular edges, smooth surface. He had no cough, dyspnea, fever or other symptoms.
