[Toxic epidermal necrolysis during a hemophagocytic syndrome secondary to Hodgkin lymphoma. Report of one case].

Toxic epidermal necrolysis (TEN) is a lethal entity, characterized by extensive epidermal necrosis and multiorgan failure. Hemophagocytic syndrome (HFS) is also a rare and lethal syndrome characterized by hyperinflammation that leads to the appearance of fever, pancytopenia, organomegaly and hemophagocytosis. The concomitance of these diseases is extremely uncommon.

[Diagnostic accuracy of serum protein electrophoresis and free light chain measurements for monoclonal gammopathies].

Background: International guidelines suggest a screening panel for monoclonal gammopathies that contains serum protein electrophoresis (SPE), free light chain (FLC) measurements and immunofixation. This combination provides the possibility of a timely accurate diagnosis.

Aim: To evaluate the sensibility of a simple screening panel (SPE + FLC).
