    TLDR Vitamin A toxicity likely caused the patient's high calcium levels.
    A case report from 1982 described a patient with hypercalcemia linked to chronic vitamin A ingestion, presenting with symptoms such as weight loss, psychiatric disturbances, total body alopecia, erosive dermatitis, and liver disease. Elevated total vitamin A levels, particularly retinyl esters, confirmed vitamin A toxicity. Other causes of hypercalcemia were ruled out, leading to the conclusion that the hypercalcemia was most likely due to vitamin A toxicity, highlighting the impact of vitamin A on bone metabolism.
