Bottom Line: They rarely exhibit intra-abdominal location.Because the symptoms emerge later on, they often remain unnoticed until they grow large.No cases at this weight and radius, originating from descending mesocolon, belonging to the myxoid sub-type, were found in our literature scan.

ABSTRACT
Liposarcomas are one of the most common primary lesions of the retroperitoneal region. They rarely exhibit intra-abdominal location. Because the symptoms emerge later on, they often remain unnoticed until they grow large. Our aim in this paper is to present a case of myxoid liposarcoma of descending mesocolon origin, 40 cm wide and weighing 7000 g, seen in a 47-year-old male patient. No cases at this weight and radius, originating from descending mesocolon, belonging to the myxoid sub-type, were found in our literature scan.

No MeSH data available.

Mentions: In histopathological examination, small “spindle-like/ovoid” and sometimes star-like shaped small atypical cells, which were stained positive with vimentin and S-100 in immunohistochemical staining (Figure 3A), showed no immunoreactions with CD117 and Desmin, resembling the histomorphology of angiomyxoma in some focuses. Widespread myxoid changes were observed (Figure 3B). The tumour cells exhibited an intermediate level of atypicality, and Ki-67 proliferation index was evaluated as 3–4% (Figure 3C). As a result of pathologic examination it was interpreted as “low-grade myxoid liposarcoma”.
