[Chloroquine neuromyopathy. One case in prophylactic maleriatherapy (author's transl)].

A case of neuromyopathy due to chronic chloroquine intoxication is reported. The neuromyopathy developped 9 months after malaria suppression therapy with chloroquine was started. The clinical picture was that of a peripherical neuropathy in the lower limbs and of a generalized myasthenic syndrome. Muscular biopsy showed typical pictures of "vacuolar myopathy". The metabolism of the drug was normal. The patient improved soon after chloroquine was discontinued.
