A Large Parathyroid Adenoma- A Textbook Case in Pathology

My interest in parathyroid surgery was prompted by an assignment from Dr. Cuello Mainardi in 1964. He required that I conduct a seminar on the topic of hypercalcemia. For this purpose, I prepared a paper for the house staff on the differential diagnosis of hypercalcemia, which includes: sarcoidosis, milk-alkali syndrome, multiple myeloma, hypernephroma, metastatic bone disease, and hyperparathyroidism. The event was pivotal to what became a life-long career as a thyroid and parathyroid surgeon.
