Consequently, symptoms are overlooked or misdiagnosed, resulting in delayed or inappropriate treatment. Early diagnosis and treatment are important for improving the quality of life of these patients. This case report describes a patient with a known history of cancer whose treatment of acrometastasis was not started for months because of a delayed diagnosis. The patient was informed that the details of the case would be prepared for publication, and he provided consent. A sixty-seven-year-old man with a medical history of non-small-cell lung cancer treated with surgical resection and radiation therapy, chronic anemia, type-2 diabetes mellitus, hyperlipidemia, hypertension, aortic stenosis, and gout presented to his primary care provider with right foot … |
