“…One important exception is intramuscular lipomas. We previously demonstrated that the reason for recurrence was related to difficulties in achieving radical surgical excision because intramuscular lipomas are often more deeply situated, not encapsulated, and have an infiltrative growth pattern [22]. The findings of this case revealed that some parts of the lesion were firmly attached to the muscles.…”

Although lipomas are common soft tissue tumors, few cases of lipoma or its variants have been reported in the oral cavity. We here described the clinical, histological, and immunohistochemical features of 24 cases of oral lipoma obtained from medical records at Nagasaki University Hospital between 1977 and 2010, and also retrospectively reviewed 603 cases of oral lipoma reported in the English literatures. The patients examined comprised 11 men and 13 women with a mean age of 59 years, ranging from 31 to 90 years. The main sites involved were the buccal mucosa (n = 9), followed by the tongue (n = 4), lip and retromolar area (n = 3), floor of the mouth (n = 2), and gingiva (n = 1). The mean tumor size was 2.0 cm, ranging from 0.2 to 5 cm. Histological analysis revealed 20 cases of lipoma, 2 cases of fibrolipoma, and one case each of intramuscular lipoma and spindle cell lipoma. Twenty-three cases were treated surgically while one case underwent biopsy and follow-up. Recurrence was not observed in any case. We reviewed the English literatures, and similar results were obtained. In immunohistochemical analysis, PCNA and ki-67 expression indices were higher in intramuscular lipoma cases than in its variants. Especially, it showed that a long time follow-up may be necessary in ki-67 positive cases.

“…This high recurrence rate cited above, according to the literature, is mainly due the difficulty of achieving complete surgical excision, since the masses are deeply situated, not encapsulated, and exhibit an infiltrative growth pattern. Even though a wide recurrence rate is described on the literature, only two cases of recurrent intramuscular lipoma on the oral cavity have been found in database 10 . One can discuss whether it is a true benign lesion, since it presents signs that suggest malignant behaviour, as the high recurrence rate and infiltration of adjacent musculature, already mentioned in this paper.…”

Intramuscular lipomas are a variant of benign lipomas that emerge inside skeletal muscle fibres at different locations and present a high recurrence rate, when not properly treated. We report a case of an oral intramuscular lipoma in 61 years old female patient that recurred 10 years after the first surgery. The authors discuss the need for a more aggressive surgical approach and highlight the importance of long-term follow-up. Descriptors: Lipoma; Mouth Neoplasms; Mouth. ResumoOs lipomas intramusculares são uma variante de lipomas benignos que emergem dentro das fibras musculares esqueléticas em locais diferentes e apresentam alta taxa de recorrência, quando não são devidamente tratados. Relatamos um caso de lipoma intramuscular bucal em paciente de 61 anos de idade que recidivou 10 anos após a primeira cirurgia. Os autores discutem a necessidade de uma abordagem cirúrgica mais agressiva e destacam a importância do acompanhamento de longo prazo. Descritores: Lipoma; Neoplasias Bucais; Boca.
