    Diffuse sclerosing osteomyelitis of the mandible (DSOM) is a nonsuppurative osteomyelitis mainly characterized by recurrent local mandibular swelling and pain. Because of the unknown pathophysiological mechanism underlying DSOM, treatment can be challenging. Reported treatment options include long-term analgesic medication, non-steroidal anti-inflammatory drugs (NSAIDs), antibiotics, corticosteroids, hyperbaric oxygen, and surgical treatment. However, these treatments cannot reliably lead to a long-lasting reduction of complaints. Recently, bisphosphonates has been reported effective in managing DSOM. We herein report a case of DSOM with a favorable response to a single infusion of zoledronate without prior treatment of other bisphosphonates. The patient was a 19-year-old woman who visited our hospital complaining of swelling and remarkable spontaneous pain in the right mandibular angle region. Under the diagnosis of osteomyelitis of the mandible, the clinical symptoms were improved by administering an antimicrobial agent and anti-inflammatory analgesic, but computed tomography (CT) showed exacerbation of bone resorption. A biopsy showed fibrosis between the bone tissue and trabeculae, a finding consistent with post-inflammatory changes. 99mTc scintigraphy showed an abnormal accumulation in the right mandibular ramus. Based on these results, she was diagnosed with DSOM. As a result of discussing with the physician in charge of internal medicine, it became the policy of the bisphosphonates and the intravenous administration of zoledronate 4 mg was enforced. Her bone sclerosis and bone resorption showed an improving trend on CT three months after the zoledronate administration, and there have been no symptoms or exacerbation of findings in three years since the administration.

    Objectives: We aimed to evaluate the clinical value of an entire-circumferential intraoperative frozen section analysis (e-IFSA) for the complete resection of superficial squamous cell carcinoma (SCC) of the tongue. Materials and Methods: A total 276 specimens from 51 patients with pT1-2, N0, mucosal or submucosal invasion SCC were analyzed to evaluate the diagnostic accuracy of the e-IFSA and the added value of the e-IFSA to iodine staining. The e-IFSA results were compared with the final histologic results obtained using permanent sections. All specimens for the e-IFSA were taken over the entire circumference 5 mm outside from the iodine unstained areas. The outline of the main resected specimen after taking these outer mucosal specimens were defined as the surgical margins determined by iodine staining alone. Results: The e-IFSA results were in excellent agreement with final histological results (Cohen's kappa value: 0.85) and the e-IFSA showed high sensitivity (100%) and high negative predictive value (100%). The actual complete resection rate with an e-IFSA was 100% (51/51), and no patient required additional resection after surgery. In contrast, 10/51 patients (20%) patients showed residual atypical mucosal epithelium at or beyond the margin determined by iodine staining alone; this difference was statistically significant (P = 0.002). The 5-year local control rate and 5-year overall survival rate after this procedure were both 100%. Conclusion: An e-IFSA has additional value when performed in conjunction with iodine staining. An e-IFSA would be useful for achieving complete resection of superficial SCC of the tongue.

    Background: Peripheral ossifying fibroma is an inflammatory or reactive hyperplasia of the gingiva that is usually small. It is formed by hard tissue in fibrous tissue, and the name “neoplastic lesion” has tended to be used frequently in Europe and America. Clinically, peripheral ossifying fibromas are painless, solitary, exophytic, sessile, or pedunculated and more frequently found in females than in males. To the best of our knowledge, there have been no reports of malignant cases. We herein report the case of giant peripheral ossifying fibroma with squamous cell carcinoma. Case presentation: The patient was an 83-year-old Japanese woman who visited our hospital with a gingival massive mass. She was referred to us for an examination and treatment because it was difficult to perform tracheal intubation for surgery of sigmoid colon cancer at another hospital. The mass measured 83 × 58 × 35 mm, and it protruded to the extra-oral region from the right maxillary premolar alveolar region. Panoramic X-ray revealed the shadow of the mass in the right maxillary premolar region, which included some hard tissue. Computed tomography showed scattering calcified images in the mass. Magnetic resonance imaging was not performed because she had vertebral artery clips and screws in her forehead. Given the above findings, we performed a biopsy under local anesthesia. However, we were unable to diagnose absolutely whether the dysplastic squamous epithelia were pseudocarcinomatous hyperplasia of the gingiva or well-differentiated squamous cell carcinoma. Therefore, tumor resection was performed under general anesthesia. The histopathological diagnosis was peripheral ossifying fibroma with coincidental squamous cell carcinoma. There have been no signs of recurrence during follow-up as of 2 years after surgery. Conclusions: The etiology of giant peripheral ossifying fibroma with squamous cell carcinoma is still not definite. Therefore, careful observation is necessary. It needs to be examined by accumulation of more cases in the future. We herein report the case of giant peripheral ossifying fibroma coincidental squamous cell carcinoma.

    Objectives: Indigo naturalis, a herbal medicine effective against ulcerative colitis, exhibits anti-inflammatory effects and induces interleukin-22-mediated antimicrobial peptide production. Anti-inflammatory activity and the prevention of secondary infection are essential for the management of chemotherapy-induced oral mucositis (CIOM); therefore, we developed an indigo naturalis ointment to be administered topically for CIOM and evaluated its feasibility. Methods: We performed a single-centre, open-label, prospective feasibility study from March 2017 to December 2018. The key eligibility criteria for the subjects were as follows: (1) receiving chemotherapy for a malignant tumour; (2) grade 1 or 2 CIOM and (3) receiving continuous oral care. The treatment protocol comprised topical indigo naturalis ointment application three times a day for 7 days. The primary endpoint assessed was feasibility. The secondary endpoints assessed were the changes in oral findings, oral cavity pain and safety. Results: Nineteen patients with CIOM were enrolled. The average feasibility (the proportion of prescribed applications that were carried out) observed in this study was 94.7%±8.9% (95% CI 90.5% to 99.0%), which was higher than the expected feasibility. The revised oral assessment guide scores of the mucous membrane domain and total scores were significantly improved. All patients reported a reduction in oral cavity pain, with a median pain resolution duration of 6 days. No serious adverse events were observed. Conclusions: The indigo naturalis ointment was feasible, and showed the potential for efficacy and safety. Larger randomised controlled trials are needed to further assess the efficacy and safety of indigo naturalis compared with a placebo. Trial registration number: UMIN000024271.
