Asymptomatic subcutaneous swelling of lower face
A 17-year-old male presented at the School of Dentistry, complaining of an asymptomatic subcutaneous swelling on the right cheek lasting around 1 year. The patient referred to a history of extraction of the right mandibular first molar (for treatment of caries) 6 months after the swelling appeared, combined with systemic antibiotic treatment for a suspected dental abscess. Trauma or previous lesions in the region were not recalled by the patient, who had no remarkable past medical or family history and no smoking or drinking habits.A symptomatic swelling of the upper lip
A 67-year-old woman presented to the School of Dentistry of the Federal University of Pelotas, Brazil, complaining of a slightly painful swelling of the upper lip, lasting around 5 years. The pain was not triggered or aggravated by cold or touch. Intraoral examination showed a 1-cm well-defined, sessile, slightly mobile, fibrous submucosal nodule on the right upper lip. The color of the lesion was similar to the adjacent normal mucosa (Figure 1). No other contributing information was collected from the anamnesis.Unusual osteolytic lesion of the jaw
An excisional biopsy specimen from a 79-year-old Caucasian man with a chief complaint of a painful swelling in the posterior left mandible was sent to the Center of Diagnosis of Oral Diseases at the Dentistry School, Federal University of Pelotas, Brazil, in 2015. The patient was fully edentulous. The surgeon found the color and texture of the oral mucosa to be normal. No positive lymph nodes were noted on extraoral examination. Comorbidities and evolution time of the lesion were unknown. The patient did not report a habit of smoking or daily drinking of alcoholic beverages.Asymptomatic gingival nodule in the anterior maxilla
A 12-year-old white girl presented at the Center of Diagnosis of Oral Diseases at Pelotas Dental School, Federal University of Pelotas, UFPel, Brazil, for the first time in 2006, with the chief complaint of a painless gingival swelling that had evolved over the previous 12 months. The patient also reported the continual habit of “pushing the gingiva” with the nails. No changes were observed in the extraoral examination. The intraoral examination revealed a sessile nodule with a smooth surface and a discrete ulcerated area, having the same color as the adjacent mucosa and measuring approximately 0.7 cm maximum in diameter (Figure 1).
