A 52-year-old woman was consulted for ecchymotic
swelling, a slightly painful middle right finger, recurrent
and spontaneously disappearing in 7 days correlated with
carrying of a heavy bag. Clinical and biological examinations
were within normal limits. Evolution was good, the
lesion disappearing in less than 10 days without any
treatment. Paroxysmal finger haematoma (Achenbach
syndrome) is a benign condition that is clinically
represented by the occurrence of an often spontaneous
occurrence of an ecchymosis located to one or more fingers.
The diagnosis is clinical, spontaneously disappearing,
investigations and specific treatments being unnecessary.
