Cutaneous botryomycosis is a chronic bacterial infection that resembles a mycetoma.
Botrys is Greek for “cluster of grapes.”
Features of cutaneous botryomycosis:
(1) There is a chronic subcutaneous nodule with draining sinuses.
(2) Small granules are often visible that consist of bacteria in a hyaline matrix (Splendore-Hoeppli phenomenon).
(3) It may be associated with a single bacterial species but often there is a mixed infection. The bacteria may be aerobic or anaerobic.
The diagnosis involves identification of the bacteria and exclusion of conditions in the differential diagnosis.
Exclusion:
(1) eumycetoma due to Actinomycosis or Nocardia
(2) eumycetoma due to a fungus
(3) mycobacterial infection
(4) abscess
