Asymptomatic nodules of the upper lip: report of a canalicular adenoma with immunoprofile presentation

Canalicular adenoma is an uncommon benign tumour that generally arises in the minor salivary glands of individuals over 60 years old. This study illustrates a case of canalicular adenoma in a 70-year-old female, presenting as two distinct asymptomatic nodules in the upper lip. Immunohistochemistry analysis was performed. Clinical features, management, histology and immunoprofile from this case and from the literature are discussed

Orthodontic therapy in patients with pericoronal hamartoma

Pericoronal lesions are undesirable for dental eruption, and they are always associated with unerupted teeth. Pericoronal lesions are common and are usually treated by extraction of the permanent tooth. Pericoronal hamartoma is a special type of pericoronal lesion, and little information about it is available in the orthodontic literature. This report presents a patient with pericoronal hamartoma on the mandibular left permanent first molar who had orthodontic treatment. Because of the similarity of the radiographic radiolucency of pericoronal hamartoma and other lesions, a differential diagnosis must be made to avoid extraction of permanent teeth

Severe manifestation of oral pemphigus

This article describes a case of pemphigus vulgaris in a relatively young patient with exacerbated characteristics, widespread lesions, and rapid evolution. A 40-year-old woman sought treatment, complaining about severe oral pain and dysphagia. Intraoral inspection revealed ulcerated lesions on the lips, buccal mucosa, and floor of the mouth. The number of lesions quickly increased and resembled erythema multiforme. She also presented blistering lesions on the back, abdomen, neck, and eyes. Incisional oral biopsy revealed pemphigus vulgaris. This report emphasizes the importance of early diagnosis of an oral biopsy in systemic diseases and the management of the lesions.

Chronic maxillary sinusitis associated with dental impression material

A 62-year-old man was referred for routine treatment of hyperplasia of the mucosa in the anterior lower jaw. An oroantral fistula was detected in the right superior alveolar ridge. The patient had no complaints. Plain radiographs showed a radiopaque foreign body in the posterior region associated with opacification of the maxillary sinus. Computed tomography showed the same hyperdense foreign body located in the posterior lower part of the sinus and an abnormal soft tissue mass in the entire right maxillary sinus. When asked about sinusitis, the patient mentioned occasional episodes of pus taste and intermittent crises of headache lasting for one week. The patient has been edentulous for 20 years. Sinus debridement was performed and the oroantral fistula was closed. The clinical suspicion of the presence of zinc oxide-eugenol paste was confirmed by microscopical and chemical analysis. After 6 months of follow-up, the fistula continued to be closed and sinusitis did not recur. This clinical case of maxillary chronic sinusitis illustrates a different odontogenic origin

Morphology and morphometry of the human sublingual glands in mouth floor enlargements of edentulous patients

Asymptomatic mouth floor enlargements may be observed in edentulous patients. These masses, which protrude from the mouth floor, may complicate the fitting of dentures and require surgery. Whether this "entity" may be considered an anatomical variation of the mouth floor or represent specific alterations in the sublingual gland is not known. Objective: The aim of this work is to investigate the morphological and morphometric aspects of the sublingual glands of edentulous patients with mouth floor enlargements and compare the glands of these patients with the sublingual glands of human cadavers. Material and Methods: Microscopic evaluation was performed on human sublingual glands from edentulous patients with mouth floor enlargements (n=20) and edentulous cadavers (n=20). The patients and cadavers were of similar ages. The data were compared using Mann-Whitney U, Fisher's exact and Student's t tests (p;0.05). Only the variables "autolysis" and "congested blood vessels" presented statistical difference between groups (p=0.014; p=0.043). The morphometric study revealed that the volume densities of acini, ducts, stroma and adipose tissue were similar between the groups (p>;0.05). CONCLUSION: The microscopic characteristics of the sublingual glands in mouth floor enlargements in edentulous patients correspond to characteristics associated with the normal aging process. The glands are not pathological and represent an age-related alteration that occurs with or without the presence of the mouth floor enlargements

The patients and cadavers were of similar ages. The data were compared using Mann-Whitney U, Fisher's exact and Student's t tests (p<0.05). Results: Acinar atrophy, duct-like structures, mononuclear infiltrates, replacement of parenchyma with fibrous/adipose tissue, mucous extravasation and oncocytosis were similar between the groups (p>0.05). Only the variables "autolysis" and "congested blood vessels" presented statistical difference between groups (p=0.014; p=0.043).
