RESUMO
Classic Kaposi sarcoma is a multifocal rare tumor originating from vascular endothelial cells with progressive evolution and little malignant predisposition. Although Kaposi sarcoma with extensive visceral involvement is sometimes observed among HIV-positive patients, tumor dissemination to visceral lymph nodes in classic SK remains very rare. We report a rare case of aggressive classic Kaposi sarcoma of the hand with a rapid and destructive development.

Lipomas are common benign neoplasms consisting of mature fatty tissue. They are usually of roundish or ovoid shape and are situated in a single anatomical region. They most frequently occur on the back and in the extremities. Most lipomas are subcutaneous and require no imaging evaluation. When deep, large and unusual in location, MRI can identify and localise these tumours and is the best exploration to differentiate lipoma and lipo-sarcoma. We describe a case of a patient with an intramuscular lipoma of the biceps brachii.
