[Diagnostic pitfall: Early arising, multiple and recurrent Marjolin's ulcer. About 8 patients (16 tumors) and literature review].

Introduction: Marjolin's ulcer (MU) is a large entity representing skin cancers resulting from the transformation of chronic wounds of a heterogeneous nature. Burn scars are the most at risk of degeneration, in particular because there are the sites of important skin tension. Atypical forms are not uncommon. The objective of this study is to present these exceptions which are underestimated.

Materials And Methods: All patients with UM in our centre between January 2011 and February 2019 have been included permitting to report the initial pathology, the location, the latency time, the histology and the management carried out.

Results: Eight patients were treated in our center for MU, they developed 16 skin cancers. Fourteen were squamous cell carcinomas (SCC). The shortest latency period was 2 months. The youngest patient was 22 years old when she was diagnosed with MU. Three patients had at least 2 synchronous SCC. One patient had a recurrence after a split-thickness skin grafting on artificial dermis and 2 patients had second locations.

Conclusion: Atypic forms are not rare. MU is commonly recurrent, multiple, early arising and may appear in young people. The treatment of chronic wounds cannot be dissociated from the treatment of contractures, otherwise the wound will inevitably reappear.
