A huge osteolipoma involving the coronoid process: a case report

Osteolipoma profundo cervicotorácico próximo ao plexo braquial – Relato de caso e revisão da literatura

“…5,6,9 Although relapses have not yet been reported, detailed monitoring and long-term follow-up are recommended due to the lack of clinical information. 5,7 We did not find studies describing osteolipoma with involvement near the brachial plexus in our searches, and, in this article, we report the first case diagnosed by imaging exams with histological confirmation.…”

“…5,6,9 Embora as recidivas ainda não tenham sido relatadas, o monitoramento detalhado e o acompanhamento em longo prazo são recomendados devido à falta de informações clínicas. 5,7 Não encontramos estudos descrevendo o osteolipoma com Fig. 4 Fotomicrografia do estudo anatomopatológico com coloração em hematoxilina & eosina e magnificação de 20x revela tumor constituído por tecido adiposo maduro com áreas de ossificação com elementos hematopoiéticos de medula óssea sem atipias, além da ausência de lipoblastos ou sinais de malignidade.…”

Ossifying lipoma: literature review and analysis of radiological imaging

“…Ossifying lipomas are generally soft, palpable subcutaneous masses that are round or discoid in shape [1]. They are generally well-defined [5,6]. They may be fixed or mobile [11,12].…”

“…C T is preferable for observing ossification, w hereas MRI is helpful for observing soft tissue such as fat. On CT, ossifying lipomas appear as well-defined tumors containing areas of both low-density fatty tissue and high-density calcification, with thin septa ( Figure 1A) [6][7][8]. These bony areas can display an irregular trabecular pattern.…”

“…Histological examination is often the most useful tool in making a definitive diagnosis of ossifying lipoma [4]. Surgical excision is often the treatment for ossifying lipoma [1,[4][5][6]. The prognosis for ossifying lipomas is the same as that of conventional lipomas [1], but due to the scarcity of clinical knowledge about ossifying lipomas, patients should receive long-term follow-up [4].…”
