[Multiple simultaneous hematomas of the finger and toe nails with subsequent onychomadesis in pemphigus vulgaris].

Multiple simultaneous subungual and intraungual haemorrhages were seen in eight fingernails and several toenails of a patient suffering from pemphigus vulgaris. As other causes of nail haematomas, such as traumas, were absent, this symptom was referred to the underlying disease. Nail and nailbed involvement in pemphigus vulgaris is extremely rare, and onychomadesis is the form that has been reported more frequently than any others.
