A Case of Generalized Plane Xanthoma Associated with Monoclonal Gammopathy of Unknown Significance / 대한피부과학회지

Generalized plane xanthoma is a group of plane xanthomas that appear as yellow to yellowish-brown flat patches or slightly-elevated plaques with a wide-spread distribution. This disease is not common and may occur in hyperlipidemic or nomolipidemic states. Generalized plane xanthoma with normolipidemia is often associated with multiple myeloma, other reticulo-endothelial malignancies and monoclonal gammopathy with unknown siginificance (MGUS). We report a case of generalized plane xanthoma associated with monoclonal gammopathy of unknown siginificance in a 40 year-old man.

A Case of Generalized Plane Xanthoma Associated with Multiple Myeloma and Hyperlipoproteinemia / 대한피부과학회지

Generalized plane xanthoma is a group of plane xanthomas that appear as yellow to yellow-brown flat patches or slightly elevated plaques with a wide-spread distribution. The disease is frequently associated with multiple myeloma or other reticulo-endothelial malignancies and monoclonal gammopathy with unknown significance, and when accompanied by these hematologic malignancies, normolipoproteinemia is invariably associated. We present a case of generalized plane xanthoma associated with multiple myeloma and type III hyperlipoproteinemia in a 48 year-old woman, and this is the first report in Korean literature.

Generalized Plane Xanthoma Associated with Monoclonal Gammopathy of Unknown Significance

Generalized plane xanthoma is less common and usually involves the eyelids, lateral side of the neck, upper trunk, and extremities. Lesions, however, may appear on any portion of the body. Cutaneous xanthomas may occur in hyperlipidemic and in normolipidemic states. Generalized normolipidemic plane xanthoma is often associated with multiple myeloma, other reticulo-endothelial malignancies and monoclonal gammopathy with unknown significance(MGUS). We wish to report two eases of generalized plane xanthoma associated with IgG monoclonal gammopathy of unknown significance.
