{Abstract}: Pyomyositis or tropical pyomyositis is an uncommon infection of skeletal muscle that may be primary or secondary. Primary type has bacterial aetiology, and Staphylococcus aureus is associated in most cases. The diagnosis requires high index of suspicion and careful assessment of radiological investigations. Diagnosis often requires magnetic resonance imaging (MRI) for better delineation of the disease process, associated site involvement and exclusion of related conditions. Evacuation of pus coupled with appropriate antibiotic therapy is the mainstay and curative in most cases. Caution, however, is required due to increased morbidity, protracted course of recovery and mortality in few cases. The association with comorbidities including immunocompromised status compounds the problem. We describe our experience with this condition in a series of five cases (four male and one female) with diverse involvement of scapular muscle. All cases had primary pyomyositis except one case secondary to shoulder joint tuberculosis. Right side was involved in three and left in two cases. Infraspinatus was commonly involved, and one case had extensive involvement around scapula. All cases were managed by one or multiple aspiration, except one managed with open surgical drainage. The outcome was good in all cases with no recurrence or complication noted in their respective follow-up. Primary care centres may play important role in the early diagnosis of this condition with clinical evaluation and judicious use of imaging. Cases with severe involvement or those requiring advanced procedures may be referred to higher centres as per the requirement. Most of the times, timely diagnosis, antibiotic therapy and drainage of the pus is required and may also be performed in the primary care level through a standard protocol.
