A case of tuberculous pyomyositis that caused a recurrent soft tissue lesion localized at the forearm.

We present the case of a 20-year-old male who had a non-traumatic soft tissue lesion (4 x 3 cm) with recurrent discharge at his right posteromedial antebrachial muscles; the patient underwent surgery twice, and antibiotic therapy was administered, but no cure was achieved with these treatments. The patient underwent surgery at our medical center. There was no history of pulmonary, gastrointestinal, or genitourinary tuberculosis (TB). Due to suspected pulmonary, genitourinary, and gastrointestinal TB, radiography and computed tomography scans were performed, and these studies disclosed no evidence of a primary origin. The erythrocyte sedimentation rate and the results of purified protein derivate testing were normal. We also detected submandibular lymphadenopathy (LAP) (2 x 3 cm) localized at a submandibular site in our patient 4 months after his first visit to our clinic. Smears were stained with Ehrlich Ziehl Neelsen (EZN) stain and culture were grown for Mycobacterium tuberculosis complex (MTC); the samples used for these assays had been obtained by incisional biopsy of the forearm lesion and by aspiration of the submandibular lymph node, and they were found to be MTC-positive. Then, a culture for MTC, derived from an induced sputum sample, was found to be positive, despite the negative results obtained with a sputum smear subjected to EZN staining. According to these results, the primary focus of the tuberculous pyomyositis and the submandibular LAP was the lungs. The lesion and submandibular LAP were both treated successfully by the administration of antituberculous chemotherapy.

[Pyomyositis].

Pyomyositis (PM) is characterized by bacterial infection and suppuration of striated muscle. It is very rarely encountered in temperate climates. Only five cases have hitherto been reported in Denmark. Two cases of PM are presented. Both of these demonstrate the difficulty of establishing early diagnosis and the severe complications of PM.

Tropical pyomyositis in India: a clinico-histopathological study.

Eighteen cases of tropical pyomyositis, aged 12-45 years, were seen over a 3-year period. There was clustering of cases in January, February and July to October. Male:female ratio was 14:4. Multiple muscular lesions (greater than 2) were common (67%). Extramuscular complications were present in 50% of the cases. Cardio-pulmonary involvement was most frequent. Muscle biopsies, done in 16 cases, showed suppurative changes (pus) in 15 cases and one case of non-suppurative myositis. Muscle necrosis, cellular infiltration with polymorphs and haemorrhage in-between muscle fibres were common.

Pyomyositis secondary to group A beta hemolytic streptococcus.

Pyomyositis is a primary bacterial infection of skeletal muscle not formed by local extension from superficial tissues. It is relatively frequently seen in tropical climates but reportedly rarely seen in temperate climates such as North America. In this report, we present a 67-year-old man with a primary Group A beta hemolytic Streptococcal infection of the quadriceps muscle of the left leg.

[The differential diagnosis of malignant soft tissue tumors: pyomyositis].

The case of a seven-year-old boy with an enlarging woody-hard mass in the upper thigh is described and the related literature is reviewed. In absence of conclusive signs of inflammation on both clinical and radiological findings a malignant soft tissue tumour was initially suspected. On operation the mass was found to contain multiple loculated abscesses, and turned out to be a subacute staphylococcal myositis (pyomyositis). Such lesions are quite common in subtropical and tropical climates, and a review of the literature indicates that the incidence of this formerly rare entity is increasing in temperate climates. A variety of factors play a role in pathogenesis, and a history of previous aseptic trauma can be found in about 50% of all cases. The most frequent location is the proximal lower limb or buttock. The clinical history and physical findings are often non-specific. Plain radiographs are non-diagnostic; ultrasound, CT and/or MRI may in some cases be equivocal and angiography sometimes is even misleading. It is important to keep this differential diagnosis in mind, especially in children.

[Pyomyositis in AIDS].

We describe two cases of pyomyositis in two patients with acquired immunodeficiency syndrome. Neither of the two cases had previous history of predisposing factors and both patients began with fever and pain at the site of the lesions. Aspiration by punction was required in addition to the antimicrobial therapy.

Pyomyositis in a temperate climate. Presentation, diagnosis, and treatment.

The cases of eighteen patients who were treated for pyomyositis between 1970 and 1988 were evaluated. The diagnosis was often delayed because other primary diagnoses were considered, including muscle strain, synovitis, thrombophlebitis, and neoplasm, and because the symptoms were vague and prolonged (maximum duration, one year). The muscles around the hip and thigh were most commonly involved (twelve patients), and Staphylococcus aureus most commonly grew on culture (twelve patients). Computed tomography aided in the accurate diagnosis of the infection and of the extent of involvement. Incision, drainage, and antibiotic therapy eradicated the infection in all patients, and they had no residual functional limitations and minimum residual symptoms.

Staphylococcal pyomyositis with idiopathic dermatomyositis.

We have described a patient with staphylococcal pyomyositis of the left pectoralis major muscle, complicating idiopathic dermatomyositis. Dermatomyositis and corticosteroids are possible predisposing factors. Patients with idiopathic muscle inflammation should be considered at risk for bacterial superinfection.

Tropical pyomyositis.

Two cases of "tropical" pyomyositis or bacterial abscess of striated muscle are presented. In the first patient, a Pakistani, computed tomography gave the clue to the diagnosis. The other patient never lived outside Belgium. His history suggested staphylococcal bacteraemia preceding trauma. Familiarity with the disease considerably reduced the delay in diagnosis and treatment.

Pectoralis pyomyositis: an unusual cause of chest wall pain in a patient with diabetes mellitus and rheumatoid arthritis.

We describe a case of isolated pectoralis swelling and tenderness, without systemic signs of infection, in a North American adult with diabetes mellitus and rheumatoid arthritis. The etiology was discovered to be pyomyositis, usually thought to be a disease of tropical climates. It is the first such case with group B Streptococcus as the causative organism.

Tropical pyomyositis in the Nigerian Savanna.

Ninety cases of tropical pyomyositis from the Nigerian Savanna are described. This is the first report from a hot and dry area of the tropics. Many of the features are similar to previous reports but affection of the younger age group is found to be a reflection of the age distribution of the population. Greater involvement of the left side of the body, spontaneous bursting of an abscess and absence of any seasonal variation are some of the differences noted. Further studies including unexplored areas of the tropics are indicated regarding the aetiology of this disease.

[Non-tropical pyomyositis].

This is a report on a 51-year-old man with all the symptoms of a non-tropical pyomyositis, namely a prodromal stage with lassitude, associated with a high fever and diffuse joint and muscle pain followed by the gradual development of a full-blown invasive stage. In the suppurative stage, the extensive pus is caused by staphylococcus aureus located in the extensor muscle of the right thigh.

Pyomyositis in Swaziland.

Pyomyositis was studied in 25 patients over a period of 1 year. The patients lived in a subtropical region, latitude about 27 degrees S, but the disease described is the same as that which occurs in the tropics and which goes by the name of "tropical myositis". The aetiology proposed for tropical myositis is regarded as not applicable to the same disease described here, of which the cause remains uncertain. This aspect of the problem is discussed with reference to the possible role played by a deficiency of ascorbic acid in the diet. Incision and drainage is the only method of treatment.

["Tropical" pyomyositis in childhood].

We report on a 14 year old boy, who developed bacterial pyomyositis (Staphylococcus aureus) in his left thigh. Ultrasound and magnetic resonance imaging were very helpful for the differential diagnosis and follow-up of this infection which in large skeletal muscles frequently is associated with abscess formation. Treatment consisted of antibiotics and surgical drainage.
