Oral fibrolipoma: Clinical case
A lipoma is a benign mesenchymal tumor that typically does not commonly involve the oral cavity. However, when it does, the cheeks and tongue are the most commonly affected areas. It presents as a papular or tumoral lesion, typically yellowish in color, with superficial blood vessels. Lipomas are soft to the touch, and their base of attachment can be sessile or pedunculated. Treatment usually involves surgery, and histopathological examination can reveal various variants, including fibrolipoma, characterized by abundant mature adipocytes and bands of mature fibrous tissue. Here, we present the case of a 55-year-old male patient who sought oral medicine consultation at the School of Dentistry of UNPHU due to a non-painful lesion that was affecting oral hygiene and eating. Upon clinical examination, a rounded, yellowish, pedunculated tumoral lesion with superficial telangiectasias, measuring approximately 1 cm in diameter, was observed in the interdental papilla between teeth 36 and 37. Based on the clinical characteristics and patient-provided data, a provisional diagnosis of lipoma was made. An excisional biopsy was performed, and pre-surgical tests, including a complete blood count, yielded normal results. Surgery was successful, and the histopathological diagnosis was fibrolipoma. Postoperative follow-ups showed a normal healing pattern, and after 3 months, there was no evidence of lesion recurrence.
Steps to reproduce
When clinically considering the characteristics of the lesion and the information provided by the patient, a provisional diagnosis of lipoma is suggested. It was decided to perform an excisional biopsy, and additionally, a complete blood count and pre-surgical tests were recommended, all of which were within normal limits.
