Oral fibrolipoma: A report of two cases and review of literature

Abstract

Fibrolipoma is a benign tumor which is classified as a histological variant of conventional lipoma. It rarely occurs in oral and maxillofacial region. When present, it occurs as a soft, smooth surfaced nodular mass that can be pedunculated or sessile. Most of the lesions are less than 3 cm in size, although it may vary. Fibrolipomas mostly affect buccal mucosa and buccal vestibule and cause functional and cosmetic disabilities. Herniation of buccal pad of fat caused by trauma may also mimic lipoma. Hence, accurate histopathological examination of lipomas is important for a correct treatment plan. Here, we present 2 cases of oral fibrolipoma that presented on the retromolar triangle area and alveolar ridge in relation to missing maxillary right first molar.

“…This distinction can only be made with certainty by histopathological examination [3]. Giant lipomas are primarily an aesthetic problem [1]. They may also lead to functional limitations because of their size and weight.…”

“…Lipomas are the most common benign mesenchymal tumor, present most commonly in the fifth or sixth decade of life and arising in any location where fat is normally present. Commonly located in the head and neck region with a 13% ratio of all lipomas [1], it usually involves in the posterior triangle. Retropharyngeal neck lipomas are a rare entity, and fewer still are giant anterior neck lipomas (> 10 cm) [2][3][4][5][6][7][8].…”

“…Anatomic discomfort and enlargement may be observed when they locate on an extremity. 1 the oral cavity, parotid gland, oesophagus and intestine is rare. In the oral mucosa, it is usually observed as a nodular, smooth surfaced, pedunculated or sessile mass.…”

Fibrolipoma em cavidade oral - Relato de caso

“…Clinicamente apresenta características semelhantes aos lipomas corporais, pois se apresentam como nódulos submucosos, circulares ou ovoides, bem circunscritos, de crescimento lento, base séssil ou pediculada, normocrômico e mole à palpação 8,9 . A coloração da lesão pode variar de acordo com sua localização, as lesões superficiais normalmente apresentam uma cor amarelada, e as profundas, uma cor rósea semelhante a mucosa normal 10 .…”

“…Embora o crescimento do lipoma oral seja comumente lento, eles podem alcançar grandes dimensões [19][20][21] . Dessa forma, todos os casos compatíveis clinicamente com essa condição devem ser submetidos a excisão cirúrgica e análise microscópica [22][23][24][25] .…”
