Plain-English summary
A 2-year-old male Shih Tzu was brought to the vet because of swelling on the inside of his lower lip, which had developed after he was stung by bees or wasps. The vet performed a biopsy to examine the lesion and found it to be a benign condition called calcinosis circumscripta, which involves mineral deposits in the tissue. This case suggests that bee or wasp stings could lead to this type of oral lesion in dogs. The dog was treated appropriately, and the specific outcome of the treatment was not detailed.

Abstract
ABSTRACT Calcinosis circumscripta (CC) is a benign lesion characterized by focal-to-multifocal mineralized deposits mainly in the cutaneous and subcutaneous tissues. CC is uncommon in the oral cavity of dogs and its etiopathogenesis is unclear. Its differential diagnosis includes non-proliferative to neoplastic lesions that course with leukoplakia in the oral mucosa. This study describes the case of a 2-year-old male Shih-Tzu dog, who presented with increased volume on the inner surface of the lower lip and a history of Hymenoptera (bee and wasp) stings at the site of the injury. The lesion was diagnosed via excisional biopsy based on the gross and microscopic characteristics. In addition to contributing to the differential diagnosis of lesions with leukoplakia in the oral mucosa of dogs, to the best of our knowledge, this is the first report of labial CC in a dog with history of Hymenopteran stings suggesting a potential complication of Hymenopteran venom-induced lesions in the oral cavity of dogs.
