Psoriasiform mucositis on the gingival and palatal mucosae treated with retinoic-acid mouthwash.

mucosae treated with retinoic-acid mouthwash A 35-year-old African-American female sought our clinic for evaluation of a burning sensation on the palate and gingival bleeding of one-year duration. Oral examination showed diffuse erythema on the upper gingival mucosa, resembling a desquamative gingivitis (Fig. 1a), and erythematous patches on the hard and soft palatal mucosa (Fig. 1b,c). No other lesion was reported either on the skin or on other mucosal surfaces. The patient was neither a smoker nor an alcohol abuser; otherwise she was in good health. Her family history presented nothing noteworthy. The diagnostic procedure began with microscopic examination of biopsies taken from the palatal and gingival mucosae, which were consistent with psoriasiform lesion (Fig. 2a–d). Periodic acid-Schiff staining of the histopathological slide sections was negative for Candida infection. A serological test for syphilis was non-reagent, and a complete blood cell count was within normal limits.

Oral mucocele of unusual size on the buccal mucosa: clinical presentation and surgical approach.

Oral mucoceles are small-size, benign minor salivary gland pathologies. The most frequent localizations of these lesions are the lower lip mucosa. However, in some cases, they grow to an unusual size and hinder the preliminary diagnosis of mucocele. The purpose of this article is to report a case of a large oral mucocele with a diameter of 3.5 cm on the buccal mucosa of a 43-years-old male patient. The surgical procedure was carried out for a complete removal of the lesion.

Tatuagem extensa por amálgama em mucosa gêngivo-alveolar

Amalgam tattoos are common exogenous pigmented lesions of the oral mucosa occurring mainly by inadvertent placement of amalgam particles into soft tissues. The diagnosis of amalgam tattoo is simple, usually based on clinical findings associated with presence or history of amalgam fillings removal. Intraoral X-rays may be helpful in detecting amalgam-related radiopacity. In cases where amalgam tattoo cannot be differentiated from other causes of oral pigmentation, a biopsy should be performed. This article deals with an extensive amalgam tattoo lesion which required a biopsy for a definitive diagnosis.

Reação liquenoide à carbamazepina em mucosa bucal: relato de caso

Lichenoid drug reactions are more common in skin, but they may also occur in the oral mucosa. It is difficult to diagnose these lesions due to their clinical similarity to the idiopathic oral lichen planus lesions. The present article reports a case of lichenoid reaction in oral mucosa associated to the use of carbamazepine, emphasizing the diagnostic process.
