Osseous choristoma of the tongue: A case report with dermoscopic study.

ABSTRACT: Osseous choristomas are rare benign lesions characterized by ectopic bone formation in the soft tissue of the head and neck region. Dermoscopy visualizes the morphological characteristics that are not observable by the naked eye, and may be used for the evaluation of calcification under the skin. The present study reports a case of an osseous choristoma arising in the tongue, and reveals the dermoscopic features of osseous choristoma from a surgical specimen. A 7-year-old boy was referred to the Department of Dentistry and Oral Surgery, with an asymptomatic pedunculated mass in the tongue. The lesion was removed completely with the adjacent normal tissue under general anesthesia. Dermoscopy of the surgical specimen revealed the hypovascular and homogeneous pattern of the lesion with round extruded whitish material. Based on dermoscopic findings, the presence of calcified hard tissue in the submucosa was verified by the dermatologist. Radiographic examination of the surgical specimen revealed the lesion contained a radiopaque trabeculated mass. Histologically, the lesion contained an osseous tissue, and the pathological diagnosis of osseous choristoma was made following consideration of the ectopic bony tissues that were localized away from the maxillo-mandibular bone. The postoperative course was uneventful with no signs of recurrence during the 36 months following surgery. To the best of the author's knowledge, this is the first report of evaluation of osseous choristoma using dermoscopy. The observation indicates the usefulness of dermoscopy for the diagnosis of oral ossified lesion in oral soft tissue.

Project description:Background Geographic tongue and fissured tongue are both common oral mucous membrane diseases relatively. The treatment of this disease is typically causative therapy because of the unknown etiology, and other afflictions. Gastrointestinal disease is one of the factors that induce geographic tongue with a fissured tongue. As an adjuvant drug that can inhibit the growth of Helicobacter pylori, the most common pathogen of chronic gastritis, Lactobacillus is widely used in clinic. However, there are seldom studies about Lactobacillus used in the treatment of geographic tongue and fissured tongue. Therefore, this case we used typically causative therapy with Lactobacillus as adjuvant to treat patient with a geographic tongue and fissured tongue with gastrointestinal disease and explore the effectiveness for further application. Case Description A 33-year-old female patient presented with a geographic tongue and fissured tongue with dysgeusia. At the first visit, there were smooth red lesions on the back of the tongue with the hyperplasia of the surrounding filiform papilla. The cracks in the middle of the tongue had a crack of about 2.5 cm long and 0.8 cm deep, and 5–6 light cracks on the tip of the tongue. The patient reported a history of chronic gastritis for 1 year, often with soft stool and gastroesophageal reflux disease. We administered drug treatment, including sodium bicarbonate tablets, Kangfuxin solution, compound chlorhexidine solution, and stomatitis spray. In addition, we suggested the patient use a yogurt machine to make and drink fresh yogurt with Lactobacillus as adjuvant everyday day and suggested a daily regimen of a light diet with no stimulating food, regular work, and sufficient rest. Ten days after the first visit, the symptoms were obviously alleviated. Twenty days after the initial diagnosis, the geographic tongue lesions had disappeared and the cracks had basically healed. The patient reported that the gastric symptoms had improved, and there was no soft stool or stomach discomfort. Conclusions This study used Lactobacillus as the adjuvant with typically causative therapy in the treatment of geographic tongue and fissured tongue.
