    Bone Formation in Peripheral Giant Cell Granuloma: A Case Report with a First Clinical, Radiographic, Ultrasonographic, Macroscopic, and Histopathologic Comparison
    (Journal of Diagnostics and Treatment of Oral and Maxillofacial Pathology, 2025-11-30) Demidov, Valentyn; Cherniak, Olha; Fesenko, Ievgen; Fil, Vladyslav; Zaritska, Valentyna; Chernetsova, Alla
    Peripheral giant cell granuloma (PGCG) is one of the benign peripheal reactive lesions of the jaws. Clinically, it is difficult to distinguish from peripheral ossifying fibroma or even metastatic tumor. We report a case of a PGCG in a 64-year-old Caucasian male. Clinically, PGCG presented as a 2.4- × 2-cm saddle-shaped pedunculated lesion of the partially edentulous alveolar ridge of the anterior mandible. The case is unique in that areas of bone formation were noted within the PGCG upon comparison of gray-scale ultrasonography (USG), macroscopic, and histopathological examination. To our knowledge it’s a first ever reported comparison in the medical literature. Indirect ultrasound imaging technique is considered in this article. Prominent intralesional vascularity upon color Doppler USG was proved upon intraoperative step when significant bleeding was noted from soft and bone tissues. Understanding by clinicians of ultrasound patterns in similar cases will facilitate differential diagnosis between alveolar ridge lesions. This paper proves ones again that ultrasound is an essential tool for the oral and maxillofacial surgeons.

    Mucous Plugs, Sialoliths, and Foreign Bodies of Salivary Glands: A Clinicosonographic Review
    (Journal of Diagnostics and Treatment of Oral and Maxillofacial Pathology, 2026-06-30) Cherniak, Olha; Fesenko, Ievgen; Demidov, Valentyn
    The goal of this narrative review is a comparative analysis of the ultrasound and macroscopic appearance of salivary gland mucous plugs with sialoliths and foreign bodies. The salivary sludge was also considered. In the world there are only two effective methods for diagnosing mucous plugs, ultrasonography and sialendoscopy. The first is simpler, cheaper and easier to perform, but more difficult to interpret for non-experienced clinicians, and the second is more difficult to perform, but easier to visualize and verify on the screen. While numerous cases of sialendoscopic images of mucous plugs in the parotid glands have been documented worldwide, sonographic images of mucous plugs in the Wharton’s duct have been noted by us in only one publication, and publications with sonograms of mucous plugs of the parotid glands, according to our literature search, are completely absent.
