Medication-related osteonecrosis in torus palatinus: Report of a case and literature review.

BACKGROUND: Medication-related osteonecrosis of the jaw bones have been frequently reported. However, its occurrence in torus palatinus is very rare with only 10 cases published in the English-language literature. CASE REPORT: We describe an additional case in a 79-year-old woman, who was referred for evaluation of a painful swelling with areas of suppuration on the hard palate. CONCLUSION: Conservative treatment was performed and after spontaneous sequestrectomy, total healing was achieved.

A primary oral mucosal melanoma of the hard palate with no recurrence: Report of a 10 years follow-up.

BACKGROUND: Primary oral mucosal melanoma (OMM) represents an extremely rare and aggressive tumor that arises from malignant transformation and clonal expansion of melanocytes in the oral cavity. The prognosis of patients affected by OMM is quite unfavorable, with survival rates lower than those described for patients with cutaneous melanoma. CASE REPORT: Here, we report a case of OMM in a 59-year-old Caucasian woman, who was referred for evaluation of a large asymptomatic pigmented lesion on the left side of the hard palate under the removable total denture. Incisional biopsy was performed, and histopathological analysis revealed the proliferation of spindle-shaped and pigmented epithelioid cells, with cellular pleomorphism. These cells were positive for Melan A, S-100, HMB-45, SOX-10, and Ki-67 confirming the diagnosis of OMM. The patient underwent partial maxillectomy and adjuvant radiotherapy. After treatment, she was rehabilitated with a palatal obturator prosthesis and has been in follow-up for 10 years with no evidence of disease. Due to the rarity in the oral cavity and the nonspecific signs and symptoms, the diagnosis of OMM is difficult and often overlooked. CONCLUSION: Therefore, multidisciplinary management from diagnosis, treatment, and rehabilitation is important to increase the expectation of cure.

The importance of early treatment of oral squamous cell carcinoma: Case report.

BACKGROUND: Oral squamous cell carcinoma (OSCC) is frequently diagnosed at an advanced stage, with the five-year survival rate varying around 50%, however, ifs the sooner OSCC in early-stage is treated, the lower the chances of recurrence and death. In this study, we described an OSCC diagnosed early, highlighting how the early surgical excision prevents the morbidity. CASE REPORT: A 74-year-old man presented a whitish and symptomatic plaque and a discreet ulcerated area on the right lateral border of the tongue. Due to close contact with the second inferior molar, a clinical diagnosis of a frictional keratosis was suspected, however as the lesion persisted after two weeks of follow-up, an incisional biopsy was performed and the microscopic features revealed an OSCC. Early surgical resection was performed, preventing the morbidity and improve benefits to patient. CONCLUSION: OSCC can manifest of several clinical forms, including indolent appearances, which can delay the diagnosis, and consequently the prognosis. Further, it is important to recognize and not neglect any intraoral lesions, in order to avoid the far more invasive surgery that a more advance disease would imply.
