Abstract

Chondrolipoma is a rare benign soft tissue neoplasm, being more common in adulthood, approximately 20% occur in the head and neck region and only 1 to 5% in the oral cavity. We present the case of a 62-year-old female patient who presented with an increase in volume in the floor of the mouth, with a five-year evolution. On clinical examination, the patient presented a painless sessile lesion with well-defined borders, located on the right side of the floor of the mouth, measuring approximately 3 cm in diameter. An excisional biopsy was performed, which revealed variable amounts of cartilaginous tissue surrounded by adipocytes arranged in lobules, confirming the diagnosis of chondrolipoma. A literature review was carried out, indicating that the most common location of chondrolipomas in the head and neck region was the tongue (46.4%), followed by the lower lip (14.3%), oropharynx (14.3%), floor of the mouth (10.7%), nasopharynx (7.1%), masseter muscle (3.6%) and sternocleidomastoid muscle (3.6%). Chondrolipomas have an undefined etiology and histogenesis, are more frequently observed in adult patients, and predominantly affect the head and neck region. The most affected areas are the tongue and lower lip, which together account for 60.7% of cases.
