Adipocytic Tumors

Epidemiological, clinical and histological features of adipose tumors in the hand and wrist: Findings from a continuous series of 37 cases

“…All the lesions were benign, with 31 being conventional lipomas (84% of cases). The other histological types were fibrolipoma (2), intramuscular lipoma (1), myolipoma (1), osteochondrofibromyxolipoma (1), angiolipoma (1). The mean size of the lesion was 3.76 cm in the long axis (1-11.5 cm) and the mean weight was 9.8 g (3-60 g).…”

They originate from mesenchymal cells and are mainly located in the trunk and base of the limbs; most of these tumors are benign [1,[4][5][6]. However, these tumors are heterogeneous from a histology point of view, and their break down is complex [1,7,8].…”

“…They originate from mesenchymal cells and are mainly located in the trunk and base of the limbs; most of these tumors are benign [1,[4][5][6]. However, these tumors are heterogeneous from a histology point of view, and their break down is complex [1,7,8]. Conventional lipomas and its benign variants make up more than half of all the soft tissue tumors, with a prevalence estimated at 2.1 per 100 persons/year [1,4,9,10].…”

“…Conversely, malignant ATs are rarer (well-differentiated liposarcoma/dedifferentiated liposarcoma, myxoid/round cell liposarcoma, and pleomorphic liposarcoma) and characterized by a proliferation of atypical cells and certain cytogenic abnormalities [1,7]. Benign and malignant lesions can appear similar on imaging studies [6,11,12] and histological analysis, making their diagnosis tricky [1,13,14].…”
