Abstract:
Dedifferentiated liposarcoma is a variant of liposarcoma, and this is characterized by the coexistence of well-differentiated liposarcoma with areas of poorly differentiated, non-lipogenic tumor and this is also known to be associated with more aggressive behavior. Dedifferentiated liposarcoma occurs principally in the retroperitoneum or the deep soft tissue of limbs, but it can also occur in subcutaneous locations. We report here on a peculiar case of dedifferentiated liposarcoma that developed in the dermis, which is an exceedingly rare location for this type of tumor. The occurrence of this tumor in the dermis made it easy to surgically remove and monitor for recurrence, and we expect this patient to have a better prognosis than that of a patient with dedifferentiated liposarcoma located in the retroperitoneum or deep soft tissue.

01:11Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.

The papillary layer is made of loose, areolar connective tissue, which means the collagen...
