Calcification or ossification of the auricle, also referred to as petrified ear, is a rare diagnosis in dermatology. In medical literature, it has most often been attributed to trauma, hypothermia and frostbite, or hypercalcemia secondary to a metabolic or endocrine disorder, such as Addison's disease. Here, we report the clinical and radiologic findings of a 79-year-old African American male whose unilateral petrified auricle was an incidental finding. He had a preceding history of hyperparathyroidism and subsequent hypercalcemia treated with a subtotal parathyroidectomy three years prior to presentation. In addition to laboratory analysis, a history and physical examination was performed which revealed no other signs of hypercalcemia. Radiologic studies demonstrated partial ossification of the external auricular cartilage on the left side. The patient was diagnosed with the rare occurrence of a petrified ear. In light of this case, we provide a discussion concerning the possible etiologies of this diagnosis including appropriate patient evaluation and possible treatment recommendations.

Hypothermia is often a sign of serious illness. Commonly reported aetiologies include but are not limited to sepsis, exposure to cold and endocrine disorders. Hypoglycaemia, a common occurrence, is rarely associated with hypothermia. We present a case of prolonged, severe hypothermia due to hypoglycaemia. A 58-year-old man with diabetes who presented with chest pain and was diagnosed with Non-ST elevation myocardial infarction. He was given nothing per mouth in preparation for a left heart catheterisation but received his reported insulin glargine dosage at bedtime. A few hours later, he was noted to have diaphoresis and hypoglycaemia, and his temperature steadily started dropping which was unresponsive to local warming. Once his hypoglycaemia was successfully treated with dextrose infusion, his temperature improved. An extensive workup revealed no infective or endocrine disorder.
