Intramuscular lipomas are unusual benign mesenchymal tumours, which infiltrate the skeletal muscle, and are exceedingly rare in the head and neck region. They commonly infiltrate the skeletal muscle fibres from which they arise and are rarely well circumscribed. We present the only documented case of well-circumscribed intramuscular lipoma arising from the sternocleidomastoid muscle. Although t...

Lipoblastomatosis is a locally infiltrative tumor of embryonic fat. We describe the MR appearance of cervical lipoblastomatosis with epidural extension. The initial MR study showed features of a soft-tissue mass; a subsequent MR examination, performed after chemotherapy, depicted the lesion as a typical lipoma of high signal intensity on T1-weighted images and of intermediate signal on T2-weigh...

Although lipomas are encapsulated benign tumors, systemic lipomatosis defines infiltrative nonencapsulated tumors resembling normal adipose tissue. Abdominal lipomatosis and intestinal lipomatosis are different clinicopathological entities with similar clinical symptoms. We describe here a case presenting with upper gastrointestinal bleeding from eroded submucosal lipoma at duodenum secondary t...

BACKGROUND Lipomas are benign soft tissue tumours, progressively expanding in volume. Beside frequent aesthetic consequences, lipomas can also exert pressure on surrounding tissues and structures. MATERIALS AND METHODS A case of a subpectoral infraclavicular lipoma compressing the axillo-subclavicular neurovascular bundle, produced unilateral brachialgia, thereby simulating a Thoracic Outlet ...

OBJECTIVE Lipomas are relatively uncommon tumours in the oral cavity; only 1% to 4% of cases occur at this site. In this study, we describe the clinical and histopathologic features of 6 cases of oral lipoma. MATERIALS AND METHODS Between 1997 and 2005, the files for all cases of oral lipoma at the oral pathology division, University of Ribeirão Preto, São Paulo, Brazil, were retrieved for st...
