Buccal Abscess With Dystrophic Calcification: A Case Report.

Dystrophic calcification, a type of ectopic calcification, refers to the pathological deposition of calcium ions in soft tissues. While cases have been reported in various regions of the body, its occurrence in the head and neck is rare. Here, we present a case of dystrophic calcification in the buccal mucosa. The patient, a 54-year-old man, initially visited his local dentist with complaints of swelling and pain in the right buccal mucosa, but the cause remained unidentified. He was subsequently referred to our department for further evaluation. At the initial visit, he exhibited swelling extending from the right buccal region to the mandible, along with redness and swelling in the right buccal mucosa near the premolars. A blood test revealed an elevated WBC count and increased CRP levels. USG showed hypoechoic areas in the right buccal region, raising suspicion of an abscess caused by infection or the presence of foreign material. The patient underwent an incision and drainage procedure, during which three tissue fragments were isolated. Pathological analysis confirmed that these were hard tissue structures distinct from teeth and bone, indicating dystrophic calcifications. Given that calcification can occur in the buccal region, it is essential to differentiate it from other conditions such as calcifying lymph nodes, phleboliths, sialolithiasis, and myositis ossificans. Accurate diagnosis requires a combination of radiological imaging, USG, clinical examination, and thorough medical history assessment.
