A 65-year-old man presents with pain, swelling and paraesthesia in his left thigh. Clinical examination revealed a large 10 × 6 cm soft-tissue mass within the left thigh. The mass is of soft-tissue density on CT and demonstrates avid contrast enhancement. There is no involvement of the adjacent bone. On MRI, the mass returns a predominantly low signal on T1W sequences and high signal on T2W sequences. Which of the following is the most likely diagnosis? LipomaLiposarcomaOsteosarcomaSoft-tissue fibromaLipoblastoma
Liposarcoma
Published in Dongyou Liu, Tumors and Cancers, 2017
Classified along with fibroblastic or myofibroblastic tumors, so-called fibrohistiocytic tumors, smooth muscle tumors, pericytic or perivascular tumors, skeletal muscle tumors, vascular tumors, chondro-osseous tumors, gastrointestinal stromal tumors, nerve sheath tumors, tumors of uncertain differentiation, and undifferentiated or unclassified sarcomas under tumors of soft tissues [1], adipocytic tumors are divided into (1) benign (lipoma, lipomatosis, lipomatosis of nerve, lipoblastoma or lipoblastomatosis, angiolipoma, myolipoma, chondroid lipoma, extrarenal angiomyolipoma, extra-adrenal myelolipoma, spindle cell or pleomorphic lipoma, and hibernoma), (2) intermediate (locally aggressive) (atypical lipomatous tumor [ATL] or well-differentiated liposarcoma [LPS]), and (3) malignant (dedifferentiated LPS, myxoid LPS, pleomorphic LPS, and LPS not otherwise specified [NOS]) [1].

In our study, we found that the lesions, such as benign and malignant tumors, below the T2-T3 levels could be resected completely through a simple low anterior cervical approach, and no postoperative complications occurred. In 2/5 of patients with lesions extending to T4, including 1 case of a lipoblastoma and 1 case of esophageal duplication with clear boundaries, their lesions were removed completely by LACA with no complications occurring postoperatively. There are significant differences between pediatric and adults due to variabilities in anatomical and pathological characteristics. In children, the cervicothoracic junction lesions can be better exposed by the supine position with shoulder pads. Carefully dissected, well-circumscribed tumors are easy to remove. There were still certain limitations in our study. The case number of our study was relatively small since cervicothoracic junction lesions are uncommon in children. We are collecting more cases to the further research in order to get statistically significant results. Therefore, it can provide a basis for whether a transthoracic surgery is required for children with cervicothoracic junction lesions.

Lipomas are common benign soft tissue tumors composed of mature white adipocytes. Lipoma, along with angiolipoma, spindle cell lipoma, pleomorphic lipoma, hibernoma, chondroid lipoma and lipoblastoma are categorized as benign lipomatous tumors [1]. Based on the depth of lesion, lipomas can be classified into superficial and deep lipomas. Superficial lipomas are typically asymptomatic and frequently found in the upper back, neck, shoulder and abdomen. Approximately 5–8% of lipomas present as lipomatosis, which lesions are microscopically indistinguishable from solitary lesion.

In the presence of a perineal tumor in a pediatric patient, multiple diagnostic entities should be considered, including congenital lipoma [3], lipoblastoma [4], schwannoma [5] and hamartoma [6]. A detailed clinical history and thorough physical examination contribute to adequate initial diagnostic guidance. Imaging tests, in addition to helping to characterize the lesion, can help to establish the degree of involvement of deep structures and the dependence of the lesion. The diagnostic confirmation of all these entities is histologic.
