Abstract
The presence of lobulated tumour arising from immature adipose tissue is called lipoblastoma when occurring as localised or discrete lesion, and lipoblastomatosis when spread diffusely. The purpose of this case study is to report a case of an 18 – year old man who presented with lipoblastoma in the left sublingual space which was found to be in close proximity with the left sublingual gland. Magnetic resonance imaging (MRI) was taken and showed the tumour was confined within the sublingual space and no penetration was noted inferiorly through the mylohyoid muscle. Tumour dimension measured clinically was 3 cm x 2 cm x 2 cm and the anterior margin of the tumour crossed the midline and entered into the right sublingual space. Complete excision with sparing of neurovascular bundle was performed under general anaesthesia. Follow-up of 2 months showed complete remission of the lesion without any complications.
Highlights
Adipocytic tumours are a subtype of soft tissue tumors representing a complex group of lesions that may show a broad range of differentiation
Our clinical diagnosis at this stage was recurrent lipoblastoma in the left sublingual space since patient had a similar clinical presentation 7 years ago on the contralateral side which was confirmed with histopathology examination (HPE) post–surgery
There could be many possible lesions arise within the corresponding structures found within the sublingual or submandibular spaces that form the floor of the mouth
Summary
Adipocytic tumours are a subtype of soft tissue tumors representing a complex group of lesions that may show a broad range of differentiation They may be divided into benign, intermediate and malignant. Occurrence of lipoblastoma in the oral cavity is rare which corresponds to less than 1.7% of all benign oral soft tissue tumours [7]. They commonly present as slow growing asymptomatic lesions with a characteristic yellow colour, soft doughy feel and lobulated [5]. Our clinical diagnosis at this stage was recurrent lipoblastoma in the left sublingual space since patient had a similar clinical presentation 7 years ago on the contralateral side which was confirmed with HPE post–surgery. The surgical specimen was consistent with our clinical diagnosis of lipoblastoma
