Idiopathic hypereosinophilic syndrome (HES) is a rare disorder marked by a sustained overproduction of eosinophils and a predilection for damage to multiple organ systems. Its neurologic involvement ranges from the central to the peripheral nervous system, and can be associated with eosinophilic myositis. We report a 68-year-old woman who had eosinophilia, eosinophilic dermatitis and eosinophilic pneumonia. She also suffered from numbness and weakness of the lower limbs. Because of long-lasting (> 6 mo) eosinophilia (> 1.5 x 10(9)/L) in the peripheral blood and the fact that no other underlying causes of eosinophilia and neurologic involvement could be identified, a diagnosis of idiopathic hypereosinophilic syndrome was made. The muscle biopsy showed infiltration of inflammatory cells, including a few eosinophils (Liu's stain). Magnetic resonance images, motor evoked potentials, somatosensory evoked potentials and nerve conduction velocities also showed abnormalities in the central and peripheral nervous systems. The pathogenesis and treatments of HES are discussed in this report.

Eosinophilic infiltration into skeletal muscle, although rare, has been described in a diverse group of conditions. It most commonly occurs in parasitic infection as focal eosinophilic myositis but can be a feature of systemic hypereosinophilic conditions such as eosinophilia-myalgia syndrome and idiopathic hypereosinophilic syndrome. The majority of cases have no discernible etiological factor. Eosinophilic myopathies should be distinguished from the commoner idiopathic inflammatory myopathies such as polymyositis and dermatomyositis. This report describes the various conditions in which eosinophilic myopathy occurs and reviews the current state of knowledge of eosinophilic myopathy.

Eosinophilia is occasionally a feature of rheumatic disease. The differential diagnosis of eosinophilia includes parasitic infection, systemic vasculitides, eosinophilic arthritis, and myopathies, together with the idiopathic hypereosinophilic syndrome and malignancy. Careful evaluation of the patient should enable an accurate diagnosis to be made. Parasitic infection is the commonest cause of eosinophilia worldwide and can cause systemic disease, as illustrated by the report of Sarcocystis myositis in a group of military personnel in Malaysia. A persistent arthropathy associated with eosinophilia, but not with parasitic infection, has been reported from the far East. Drugs may also cause eosinophilia, and there has recently been much discussion of the relation between Churg-Strauss syndrome and the leukotriene antagonist zafirlukast. The present view is that reduction of steroid dose allows unmasking of previously undiagnosed Churg-Strauss syndrome. The idiopathic hypereosinophilic syndrome may represent a lymphoproliferative process; evidence for this comes from the demonstration that many patients have a clonally expanded population of aberrant T cells.

Idiopathic hypereosinophilic syndrome (HES) is a heterogeneous group of disorders with the common features of prolonged eosinophilia of underdetermined cause and multiple organ system dysfunction. Focal eosinophilic myositis is an uncommon manifestation of HES. We report a case of focal eosinophilic myositis with tender muscle swelling followed by proximal weakness, but without non-systemic symptoms and muscle trophism in the lower limbs. Muscle biopsy specimen showed acute myositis with eosinophil infiltration. Electromyographic features were typical of myositis. The clinical and biochemical response to corticosteroids was excellent, and a relapse that occurred because the steroid dose was not lowered, responded well.

We describe a case of idiopathic hypereosinophilic syndrome manifested by an axonal sensory-motor polyneuropathy (ASMP) and signals of myositis. A 20 year old woman began with progressive gait impairment with drops and presented with subacute lower limb edema associated with paresthesis and cramps. She showed hypotonia in the lower limbs, absence of knee and ankle jerks, steppage gait, and decreased sensation on both legs. Examinations of stools were negative. Blood examination showed 7700 leukocytes with 24% (1848/mm(3)) eosinophils. Electrodiagnostic studies showed axonal lesion in sensory and motor nerves. Muscle biopsy showed type 2 muscle fibers atrophy with discrete inflammatory cells, predominantly lymphocytic in perivascular and interstitial locations. She was treated with prednisone and all the symptoms subsided after two months.

Hypereosinophilic syndrome is a rare disorder of the hematopoietic system. The disease is characterized by continuously high number of eosinophils (>1.5 x 10(9)/L) for more than six months. Other possible causes of hypereosinophilia, such as allergic and parasitic diseases, malignant disease, Churg-Strauss disease and infection should be eliminated. The most common manifestations of hypereosinophilic syndrome are pulmonary, skin, gastrointestinal, cardiac difficulties and neurologic lesions. Numerous neurologic lesions have been described, in particular of the central and peripheral nervous systems. Review of the literature revealed the following to have been recorded so far: mononeuritis multiplex, sensory polyneuropathy, radiculopathy, myalgia, myositis and perimyositis, neuropathy, ataxia, paraplegia, ophthalmologic abnormalities, optic neuritis, hemiplegia-hemiparesis, spasmodic quadriplegia, seizures, meningitis, cerebral infarction, organic psychosyndrome, other mental changes, stroke, temporal arteritis, leptomeningeal dissemination, memory deficits and dysarthria.
