<unk>  (or acquired partial lipodystrophy, cephalothoracic lipodystrophy, and progressive lipodystrophy)) is a rare form of lipodystrophy, 
which usually first affects the head, and then spreads to the thorax.
It is named for Luis<unk>  Roviralta (1855–1928), a Spanish physician, and Arthur<unk>  (1879–1942), a German physician.
Some evidence links it to LMNB2.
