Impact of hematologic complete response in the treatment of sporadic late-onset nemaline myopathy associated with monoclonal gammopathy.

ABSTRACT

Monoclonal gammopathy of undetermined significance (MGUS) may be associated with pathologies with severe neuromuscular manifestations such as sporadic late-onset nemaline myopathy (SLONM). We describe a difficult to diagnose case of SLNOM with marked clinical improvement after achieving gammopathy complete hematologic response.
