What Is Causing This Man's Severe Hyperkeratotic Lower-Extremity Lesions?

摘要

A 69-year-old man with history of coronary artery disease, hypertension, hypothyroidism, obstructive sleep apnea, tobacco use, and medical nonadherence presented to the emergency department with dyspnea and subsequently was admitted to the intensive care unit for an exacerbation of chronic obstructive pulmonary disease. Although they were not directly related to his chief concern, severe hyperkeratotic lesions were noted on the patient's bilateral lower extremities.
