Actinomadura Pelle171eri Causing White Grain Mycetoma
Abstract:
Actinomadura pelletieri causing white grain mycetoma pedis in a 32 year old farmer is reported. The right foot was swollen, firm painless, non tender and had a number of small nodules breaking down to form sinuses. The seropurulent discharge contained dirty white grains measuring 0.5 to 1 mm, composed of unfragmented filaments of bacterial width. Histologic examination of the biopsy material revealed the characteristic granule of A. Pelletieri and culture yielded typical coral red colonies.
Insights
A case of white grain mycetoma pedis caused by Actinomadura pelletieri in a farmer is presented. The infection manifested as foot swelling, nodules, and sinuses with characteristic dirty white grains.
