Suspected Hypercalcemia of Benignancy Associated with Canine Vaginal Leiomyoma

Hypercalcemia was identified in a canine patient with a benign vaginal leiomyoma. Subsequent diagnostic workup did not reveal hypercalcemia of malignancy. Surgical resection of the leiomyoma resulted in a conversion to normocalcemic status. Although rare, hypercalcemia of benignancy should be considered in a patient in which hypercalcemia is identified via clinical pathology.
