Primary melanoma of the oral cavity: ten cases and review of 177 cases from literature

Oral melanoma is an infrequent but aggressive neoplasm. In contrast to cutaneous melanoma, it does not have a defi ned set of clinical and pathologic classifi cation criteria. We present 10 cases of primary melanoma of the oral mucosa, and review 177 cases published in the international literature. Patients and methods: We compiled a database of patients seen at our department between years 1990 and 2004. A retrospective study of this data was performed. Age, sex, localization and histopathology were all considered. Tobacco consumption and the presence of traumatic factors in the oral cavity were also compared. We compiled another database with 177 cases reported in the international literature during the same time period. Primary and metastatic cases were included.Age, sex and localization were among the factors taken into account. Results: Of the total of 23,685 patients seen at our department in this period, 399 (1.68%) were diagnosed with cancer, 10 (2.5%) of whom were diagnosed with primary oral melanoma. The gender distribution was 1:1, and ages ranged from 30 to 88 years old, with a mean of 67.5 years old. In 80% of the cases, the oral melanoma was localized in the maxillary, and in 20% of the cases, it was localized in the mandible. No connection was found with tobacco consumption. In 60% of the cases, we believe there was a link with prosthetic microtrauma. Of the 177 cases described in the literature, 89% were primary and 11% secondary. The gender distribution was 46.9% female and 53.1% male. Ages ranged from 16 to 91 years old, with a mean of 59.2 years old. Localization: 68.36% maxillary, 11.30% mandible and 20.34% in various oral localizations

Helicobacter Pylori Infection of Lingual Dorsum: Risk of Gastric Infection Helicobacter Pylori

The role of Helicobacter pylori in the oral cavity has been researched/studied by our study group for the last 28 years. At that time, there wasn’t a clinical entity that included Burning, Lingual Papillary Hypertrophy and Halitosis (BHH) together. However, the patients who presented this condition did not find an effective response to their demand. In some cases, a therapeutic diagnosis of Chronic Candidiasis was made in relation to Lingual Papillary Hypertrophy and they were referred to Periodontics Services for their Chronic Halitosis for evaluation and treatment. Many of these patients did not resolve their clinical symptoms, in their subsequent check-ups. The burning of the mouth was usually diagnosed as Burning Mouth Syndrome. A considerable percentage (60%) of these patients reported suffering from chronic gastric discomfort without receiving treatment, because when they consulted with the physician or with the gastroenterologist, their symptoms were associated with stress.Fil: Muiños, Antonio Luis.
