A 35-year-old woman contracted severe trichinosis which was atypical in that it lacked a gastrointestinal prodrome and periorbital edema, and in that eosinophilia developed only late in the course of the illness. The patient developed an incapacitating myositis as well as complications of encephalopathy, myocarditis, and retinal hemorrhages, resulting in severe debilitation of more than two and one-half months' duration. Muscle histochemistry illustrated previously unreported features.

Two cases of granulomatous dermatitis with eosinophilla (Wells' syndrome) are reported. With Wells' original four cases, these two cases define a distinctive dermatosis with onset as cellulitis and formation of solid edema and either final spontaneous resolution or resolution with steroid therapy. Microscopic study showed diffuse tissue eosinophilia and fibrinoid flame figures, evolution of associated focal necrobiosis, and formation of focal microgranulomas associated with eosinophils. Biopsy of muscle and fascia showed comparable fasciitis and eosinophilic myositis. Immunofluorescence in one case disclosed fibrin in the dermis and lgM, lgA, and C3 in the blood vessels of the muscle. Recurrences of the lesions often appeared to be related to drug administration or surgery.

Six patients with eosinophilic fasciitis are presented. This syndrome is characterized by indurative swellings of arms and legs, with rapidly progressing difficulties in extending elbows, wrists, and fingers, and often limited motion of shoulders and ankle joints. Pain when contracting muscles, and weakness of proximal muscles and hand grip are common features. The frequent occurrence of localized skin lesions has presented differential diagnostic difficulties to systemic sclerosis and to polymyositis. Visceral involvement and Raynaud's phenomena, however, are absent or mild. Blood eosinophilia, hypergammaglobulinemia, and unspecific signs of inflammation are found. Biopsy of muscle fascia gives characteristic histopathological findings of cell infiltrations (mostly mononuclear cells, frequently eosinophils) and vascular proliferation, in the middle layer of a thickened fascia. Skin changes are prevalent, but not conclusive for the diagnosis, and myositis in some patients might be difficult to distinguish from polymyositis. The importance of the clinical recognition of eosinophilic fasciitis and the inclusion of fascia in diagnostic muscle biopsies, is underlined.

The authors report two cases of the Shulman's syndrome. Twenty one cases of this new entity are found in the literature. The main signs are the acute painful onset after an unusual physical exertion, the development of fasciitis, and (or) myositis, and (or) scleroderma of limbs, the absence of Raynaud's phenomenon, visceral involvement, constant eosinophilia and hypergammaglobulinemia; the prognosis is good with an improvement sometimes spontaneous or coincident with prednisone therapy. One of the observations is interesting by the association with Gougerot-Sjogren's syndrome, and a familial case of morphea. The prognosis in this case is mediocre: failure of corticotherapy, and incomplete remission with cyclophosphamide.

After 2 weeks of ingestion of 130 g L-Tryptophan a 52 year old female develops an Eosinophilia Myalgia Syndrome with acute onset of deep venous thrombosis of forearm and possible initial cardiac manifestation featuring intermittent sinustachykardia. This is followed by a severe chronic disease (follow-up 15 months) with diffuse scleroderma and sensomotoric polyneuropathia. The deep muscle biopsy-specimen shows mononuclear infiltration of fascia and interstitial myositis with rare eosinophils. A blood eosinophilia (900/ul) occurs only in the initial acute onset of the illness. Plasma level of Kynurenine is significantly high (4000 pmol/ml), collagenneosynthesis is activated (Procollagen type III peptid 0.927 U/ml). No significant clinical improvement was seen with Acathioprine (100 mg/d) and Prednisolon (40-60 mg/d), after treatment with Ciclosporin scleroderma regresses completely, polyneuropathy is persisting.

We describe a 53-year-old women with eosinophilia-myalgia syndrome who suddenly developed severe persistent myalgias of her arms, legs, back, and shoulder after a 5-month period of daily L-tryptophan ingestion, associated with fever, progressive stenocardia and left-sided congestive heart failure. Laboratory tests showed a leukocytosis of 11.2/nl with 3.14/nl eosinophils and an elevated erythrocyte sedimentation rate. There was a marked, predominantly proximal sclerosis of her arms, legs and trunk with a brownish discoloration. The skin of her arms and legs appeared dimpled (peau d'orange). Findings of the electrophysiological examinations were consistent with sensory neuropathy and myositis. Remarkable fasciitis and interstitial myositis were present in a biopsy specimen (from skin to muscle) taken from her thigh. However, eosinophilic infiltrates were rare. Angiography revealed an apical obstructive cardiomyopathy. In this paper, we describe the clinical findings, the course over 2 years, as well as the therapeutic management. Furthermore, the most important differential diagnoses are discussed and the literature is reviewed with special attention given to more recent pathogenic insights into this newly recognized multisystem disease.

In 1981 epidemic poisoning with adulterated cooking oil occurred in Spain, affecting more than 20,000 people. The condition caused has since become known as the toxic oil syndrome (TOS). About 10-15% of the patients with acute symptoms developed a chronic disease with scleroderma-like skin manifestations, polyneuropathy and myositis. While the acute phase of the TOS was characterized by eosinophilia and elevated IgE, the chronic stage involved humoral autoimmune phenomena, such as antinuclear and antinucleolar antibodies, in many cases. In women with the chronic phase of TOS there was a possible prevalence of HLA-DR3 and HLA-DR4. The recently characterized eosinophilia-myalgia syndrome (EMS), which is thought to have been induced by contaminated L-tryptophan preparations, is similar to the TOS in some particulars. Understanding of the toxicological, immunological and genetic pathways leading to these diseases might give us some insight into the pathogenesis of spontaneously occurring autoimmune diseases, such as systemic scleroderma.

Animal models have proven very useful in furthering insight into a number of muscle diseases. Studies of ethanol-fed rats are being used to understand the pathogenetic mechanisms underlying acute and chronic myopathy induced by ethanol. Several animal species, including mice, dogs, and cats, develop X-linked muscular dystrophies, which have genetic defects identical to those of Duchenne muscular dystrophy. As in the human disease, these animals lack dystrophin. They are being used to investigate the mechanisms by which lack of dystrophin results in weakness and to examine myoblast transfer as a treatment modality. A model of eosinophilia-myalgia syndrome has recently been induced in Lewis rats by the feeding of L-tryptophan samples that were implicated in the clinical syndrome in humans, making possible studies of the pathogenesis of this interesting new entity. A dermatomyositis-like syndrome occurs spontaneously in dogs, and polymyositis-like illnesses can be induced in mice by immunization with muscle or following infection with selected viruses, especially enteroviruses. Study of the latter is helping us understand mechanisms in the etiology and pathogenesis of inflammatory myositis and virus-induced autoimmunity.

We describe a patient who developed fever, fatigue, muscle weakness, dyspnea, skin rash, and eosinophilia after taking "high doses" of tryptophan for insomnia for two years. A gallium-67 scan revealed diffuse increased uptake in the lung and no abnormal uptake in the muscular distribution. Bronchoscopy and biopsy confirmed inflammatory reactions with infiltration by eosinophils, mast cells, and lymphocytes. CT scan showed an interstitial alveolar pattern without fibrosis. EMG demonstrated diffuse myopathy. Muscle biopsy from the right thigh showed an inflammatory myositis with eosinophilic and lymphocytic infiltrations.

Several groups of cases of fasciitis and myositis with eosinophilia are reported. The common features are inflammation into fascia and/or perimysium, and/or muscle fibers; eosinophilia in blood and/or in muscle biopsy. The following classification of 24 cases is suggested: at one end of the spectrum are fasciitis with eosinophilia: diffuse fasciitis (Shulman syndrome): 10 cases (3 with hematological complications); 2 cases of diffuse fasciitis with muscle atrophy; 3 cases of restricted fasciitis. Relapsing perimyositis with eosinophilia belong to the same spectrum, either diffuse (5 cases) with myalgias, or localized (2 cases). Other cases are focal myositis or multiple myositis, polymyositis with eosinophilia. The relationship among these cases is discussed. There is a continuum among the different groups. The pathophysiology remains unknown.
