In the head and neck region, there are some reports of its occurrence in the bony skeleton; however, it is extremely rare in soft tissues. Herein, we report a case of tongue granuloma requiring the differentiation of LCH and ECD. A 64-year-old man was referred to our hospital for swelling of the tongue and oral floor. We performed a biopsy and diagnosed ECD pathologically. However, as no bone lesions were identified in other parts of the body, a diagnosis of tongue granuloma was made. Following systemic administration of corticosteroids, the swelling of the tongue and oral floor completely disappeared. Steroids were gradually decreased, and there were no signs of recurrence of the disease. This case underscores the importance of considering ECD in the differential diagnosis of granulomatous lesions in the head and neck, even in soft tissues, and highlights the efficacy of corticosteroid therapy in managing associated symptoms.</div></div>","PeriodicalId":45034,"journal":{"name":"Journal of Oral and Maxillofacial Surgery Medicine and Pathology","volume":"37 2","pages":"Pages 385-390"},"PeriodicalIF":0.4,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143151375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A defected area mostly left to heal spontaneously. It doesn’t have a definite protocol in the literature, when the area will be left to heal spontaneously or when supported with materials such as plates, screws, grafts, especially in intermediate-sized defects.

However, osteonecrosis of the jaw (ONJ) is a known side effect with each of them (called BRONJ or DRONJ, respectively). BRONJ and DRONJ are intractable, and no sound/solid treatments have been established. Some reports note that denosumab carries a greater risk of ONJ than NBPs, and that they mutually augment the risk. Our previous animal and in vitro studies led us to suppose that etidronate (a bisphosphonate not containing nitrogen) may be effective against BRONJ, and we reported that etidronate ameliorated BRONJ in all 13 of the patients we tested. Here, we add a case in which etidronate healed stage 3 ONJ caused by alendronate (an NBP) followed by denosumab. We first treated her with minocycline (a bacteriostatic antibiotic) and then etidronate. Pain and drainage disappeared with minocycline. Within 3 weeks after the start of etidronate, bone exposure was markedly reduced and it had disappeared within 6 months, being followed by osteogenesis in the injured area and fracture-line disappearance. These results suggest that (i) in the present patient, the major cause of ONJ might have been alendronate, with denosumab possibly promoting its progress, (ii) etidronate is effective against BRONJ caused not only by NBPs, but also by NBPs + denosumab, and (iii) minocycline is suitable as a combination drug with etidronate, because in addition to its bacteriostatic effect, minocycline has various effects helping to ameliorate ONJ, including analgesic, anti-inflammatory, and bone-forming effects together with its high affinity for bone.</div></div>","PeriodicalId":45034,"journal":{"name":"Journal of Oral and Maxillofacial Surgery Medicine and Pathology","volume":"37 2","pages":"Pages 348-355"},"PeriodicalIF":0.4,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143150328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
