Pseudosarcomatous lesion of the soft tissues is a term used in the present study for various soft tissue lesions and tumours easily clinically or histologically, or both, misinterpreted as sarcoma. Eighty-one cases, that is to say 10 per cent of all tumours classified and reported to the Swedish Cancer Registry as malignant soft tissue tumours during the 6-year period studied (1958-1963), were reclassified as pseudosarcomatous lesions of the soft tissues. Forty-seven cases were classified as pseudoarcomatous proliferative lesions of the soft tissue with or without bone formation; 38 cases of nodular fasciitis, 1 of proliferative fasciitis and 8 of proliferative myositis. In 3 of these cases there were mixed forms of proliferative fasciitis and proliferative myositis with areas compatible with the diagnosis of nodular fasciitis evident in all cases. Twenty-two cases of atypical fibroxanthomas of the skin were next in frequency, followed by 7 ancient neurilemmomas, 2 spindle cell lipomas, 1 pseudomalignant osseous tumour of the soft tissues, 1 pigmented villonodular synovitis and 1 juvenile xanthogranuloma. An attempt is made to explain the reasons for these erroneous diagnoses of sarcoma and it is stressed that for these lesions the conventional histological criteria for malignancy are not valid. The awareness and knowledge of the existence of these particular entities are therefore considered mandatory for an accurate diagnosis.

A patient with the clinical picture of quadriceps myopathy was shown to have an underlying myositis. Review of the literature showed myositis to be a rare cause of the 'quadriceps syndrome' but it is important to identify this group because they are potentially treatable with corticosteroids.

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.

Myositis and septicemia caused by Acinetobacter calcoaceticus were diagnosed in a mare. The infection was characterized clinically by ventral swelling and edema, diarrhea, listlessness, and rectal temperature of 39.4 C. The mare was treated symptomatically for 2 days but died on the 3rd day. Conditions seen at necropsy were myositis, enteritis, typhlitis, colitis, and hepatitis. Lymph nodes were moderately enlarged throughout the body. Gross lesions in musculature were edema, scarring, petechiae, and an occasional exxhymosis. The enteritis was catarrhal, with excessive mucus and moderate hyperemia. The typhlitis and colitis were hemorrhagic. The swollen liver had a diffuse mottled pale and red pattern. Microscopic lesions in skeletal muscle consisted of petechiation, necrosis, scarring, and edema. Cardiac muscle was also scarred and necrotic, but edema was not prominent. Periacinal necrosis was found in the liver. Acinetobacter calcoaceticus was isolated from myocardium and liver.

We retrospectively reviewed the manifestations of influenza A2 in 83 hospitalized young children. Our purpose was to define the spectrum of clinical illness in this age group. Findings included fever (91%), vomiting or diarrhea (49%), pharyngitis (34%), pneumonitis (29%), otitis media (24%), conjunctivitis (13%), croup (13%), and bronchiolitis (6%). Neuromuscular manifestations occurred in 16 patients (19%) and included seizures, apnea, opisthotonos, and myositis. Three children had cerebrospinal fluid pleocytosis. Children younger than 3 months of age had fever less often and gastrointestinal symptoms more often than older children. Threee children died of progressive pneumonitis. We conclude that influenza A2 may cause a wide range of respiratory and neurologic findings in infancy and early childhood.

Echinococcus alveolaris infections were found in 5 members of a family and at least 3 of them also suffered from myotonia congenita. A muslce biopsy, performed in 1 case because of a pathological EMG finding allowed a diagnosis of parastic myositis caused by E. alveolaris to be made. In a further case, X-rays demonstrated calcification of an Echinococcus cyst in the thigh. Since is it only on rare occasions that these parasites are found in muscle tissue, factors are then discussed which might in some way be responsible for this high rate of E. alveolaris lesions in the muscles of patients with myotonia congenita.

A case of polymyositis in a 15 year old girl demonstrating the clinical course of an infectious disease is presented. The Coxsackie virus B2 was isolated from the stools, and serum antibodies were detected. Histologic examination of muscle showed signs of myositis. The patient was treated with cortisone and recovered completely. Possible viral etiology of the polymyositis is suggested.

Seventy episodes of Staphylococcus aureus sepsis occurring over a nine-year period in pediatric cancer patients are reviewed. Prominent findings at the time of diagnosis included fever, granulocytopenia, and active malignancy. Probable or suspected sites of primary infection were present in 40 episodes (57%). Serious direct complications of staphylococcal sepsis included only three cases of pneumonia and one of myositis. However, second infections by other organisms developed in 16 episodes (24%), resulting in nine nonstaphylococcal infectious deaths during therapy. Endocarditis and osteomyelitis never occurred in this group of patients. The median duration of antistaphylococcal therapy was 15 days.

In the five-year period 1964-68 1,335 patients were admitted to Mulago Hospital, Kampala, with tropical myositis. The marked increase in the number of admissions during the study period is attributed to a change in the utilization of the hospital rather than to a true increase in the incidence of the disease. There was found to be only slight variation in incidence between different age and sex groups and there was no convincing evidence that immigrants from high altitude areas, where the disease is rare, were at different risk. There was statistically significant month-to-month variation in admission rates but there was no apparent correlation with rainfall, and no marked seasonal variation. During the quinquennium there was a changing pattern of admission rates for patients from different counties, and some evidence of 'space-time' clustering. These findings are compatible with the primary muscle damage being induced by a virus or the presence of aberrant hookworm larvae, but an ingested toxin cannot be excluded. Trauma may also play a role in determining localization of the disease in some cases.

The cases are discussed of two patients with an avulsion fracture of the inferior-anterior iliac spine. Both were treated by surgical fixation. Symptomatology, complications of conservative therapy and the results of surgical treatment are described. Ossifying myositis did not occur in these patients.
