[Scapulo-thoracic mycetoma. A rare localization, a particular form]

Area of Science:

• Medical Mycology
• Tropical Diseases
• Dermatology

Background:

• Mycetoma is a chronic fungal infection with rare presentations.
• Distinguishing mycetoma from other tropical diseases is clinically important.

Observation:

• A 55-year-old male presented with a scapulo-thoracic tumor 10 years post-injury.
• The tumor was a polyfistular mass on the left shoulder, lacking visible red granules.
• Histological examination revealed Streptomyces pelletieri granuloma.

Findings:

• The case represents an uncommon encapsulated and polyfistular scapulo-thoracic mycetoma.
• Streptomyces pelletieri was identified as the causative agent.
• Cotrimoxazole treatment yielded positive results.

Implications:

• Scapulo-thoracic mycetoma requires consideration in differential diagnoses in Sahel regions.
• This rare form can lead to complications like osteitis or pleuro-pulmonary involvement.
• Accurate diagnosis is essential for effective management of mycetoma.
