INTRODUCTION: An uncommon form and a rare localization of mycetoma is reported. The aim of this report was to distinguish this inhabitual form of mycetoma from some tropical diseases like onchocerca and other fungal diseases. CASE REPORT: A 55 year old man was admitted 10 years after a septic worm-hole for a scapulo-thoracic tumor. This encapsulated mass was a bending and rounded polyfistular one attached to the dorsal aspect of left shoulder. The fistula discharge a serosanguineous or purulent exudate. The characteristic red granule was not visible. The tumor was removed and histological examination was performed. A typical granuloma of red granule of streptomyces pelletieri was found. A good result was obtained with associated cotrimoxazole treatment. DISCUSSION: Scapulo-thoracic form included: scapular, axillary and chest form of mycetoma. All these localizations are rare. One of them can be complicated by osteitis or pleuro-pulmonary localization. Streptomyces pellitieri is the actinomycetic causal agent. This encapsulated form is uncommon. CONCLUSION: Scapulo-thoracic mycetoma is rare. Encapsulated and pedicular form is uncommon. Around Sahel areas, differential diagnosis must be evoked such as parasitic and mycobacterial infections.
