Mycetomas are subacute or chronic infections usually localized on unpr
otected skin areas and caused by fungi or Actinomyces. We report the c
ase of a patient who suffered a splinter injury on his wrist after a m
otor accident. Six months later a cutaneous abscess with Actinobacillu
s acinomycetemcomitans developed on his wrist. Complete healing was ob
tained within 1 month after administration of ceftriaxon and doxycycli
ne. The therapeutic management will be discussed.
