Subcorneal pustular dermatosis and IgA lambda myeloma: a uncommon association but probably not coincidental.
The present report deals with a case of subcorneal pustular dermatosis (SCPD) associated with IgAlambda myeloma and reviews the literature for similar cases. Three relevant points arise from this case: the association of the dermatosis with an IgAlambda myeloma that, as far as we know, has been described only three times previously; the longest period of time between the onset of the dermatosis and that of the myelopathy observed up to now; the good therapeutic response to etretinate, useful in the management of severe recalcitrant forms of SCPD.
