Histopathologically, ALT/WDL tumors are divided into adipocytic/lipoma-like, sclerosing, and inflammatory variants with adipocyte/lipoma-like being the most common. Adipocytic/lipoma-like ALT/WDL tumors consist of lobules of mature fat cells variably intersected with irregular fibrous septa (see the adjacent H&E stained photomicrograph).
A myxoid liposarcoma is a malignant adipose tissue neoplasm [1] of myxoid appearance histologically.. Myxoid liposarcomas are the second-most common type of liposarcoma, representing 30–40% of all liposarcomas in the limbs, occurring most commonly in the legs, particularly the thigh, followed by the buttocks, retroperitoneum, trunk, ankle, proximal limb girdle, head and neck, and wrist.

Cutaneous lipomas are rare in children, but these tumors can occur as part of the inherited disease Bannayan-Zonana syndrome. [40] [41] Lipomas are usually relatively small with diameters of about 1–3 cm, [42] but in rare cases they can grow over several years into "giant lipomas" that are 10–20 cm across and weigh up to 4–5 kg. [43] [44]
Four main hypotheses have been proposed for the cellular origins of carcinosarcoma, based largely on the pathology of the disease. [1] [3] First, the collision tumor hypothesis, which proposes the collision of two independent tumors resulting in a single neoplasm, based on the observation that skin cancers and superficial malignant fibrous histiocytomas are commonly seen in patients with sun ...
