“…Paget first reported an infiltrating lipoma of the trapezius muscle in 1853 8 . Subsequently, the surgical literature has further divided the infiltrating lipoma into two subtypes: intermuscular and intramuscular 3–7 . The intermuscular variant is more common and is felt to arise from between the muscle bundles, probably from the intermuscular fascial septae 3 .…”

“…In addition, lipomas can be located in parosteal, interosseous, visceral, intermuscular, or intramuscular sites 2 . The latter two types have been referred to jointly as infiltrating lipomas 3–7 . The depth of penetration of these tumors and possible involvement of nerve and vascular tissues may require referral for definitive surgical treatment.…”

The typical lipoma is an encapsulated subdermal tumor, usually easily removed if necessary. We recently encountered two lipomas that infiltrated muscles of the forearm. Excision of infiltrating lipomas may be complicated by their deep location and potential involvement of vascular and neural structures. This paper should increase dermatologists' awareness of this uncommon variant and facilitate appropriate referral for definitive treatment. We believe that this is the first report in the dermatologic literature of infiltrating lipoma of the upper extremity.

Lipomas are the most frequent benign mesenchymal neoplasms of mature fat cells found commonly on the back and upper extremities usually occupying the subcutaneous plane. Intramuscular lipomas are rare and may mimic malignant lesions. Magnetic resonance imaging can not only identify and localise these tumours but also differentiate them from malignant liposarcomatous lesions. Here we present a case of intramuscular lipoma of the medial head of Triceps brachii in a 70 year old male clinically mimicking as nerve sheath tumour of the ulnar nerve.

“…The first documented case of an infiltrating lipoma appears to have been described by Paget in 1853 [8]. Infiltrating lipomas have been divided into two types, intramuscular and intermuscular, depending upon their sites of origin [9,10].…”

This study correlates the magnetic resonance imaging characteristics with the pathologic findings in rare benign fatty soft tissue tumors in four children. A review of the literature is presented. Two cases of infiltrating lipoma displayed bright signal on both T1- and T2-weighted images, similar to that observed in subcutaneous fat. Histological study revealed extensive muscle infiltration by mature fat, with some areas of total fatty replacement. The case of facial lipomatosis revealed an extensive process of fatty invasion of adjacent soft tissue and osseous deformity by mass effect of the tumor. This lesion was bright on T1- and T2-weighted images. Histopathologic examination showed widespread invasion of squamous mucosa and skeletal muscle. The single case of lipoblastoma involved the presacral region and right buttock. This lesion, although bright on both T1 and T2 weighting, was relatively hypointense to subcutaneous fat on T1. Microscopic examination revealed a well-encapsulated fatty mass made up of cells ranging from lipoblasts to mature lipocytes. In childhood, when fatty lesions are almost always benign, a morphologic characterization by magnetic resonance may be sufficient basis on which to make critical therapeutic judgements.
