Abstract

The post-traumatic pseudolipoma (PTPL) is a unencapsulated proliferation of mature adipose tissue that develops after a local trauma. We report a case of a male child, who presented with a tumor on the left forearm which appeared weeks after a local blunt trauma. We perform a biopsy of the lesion and the diagnosis of post-traumatic pseudolipoma was established. This case exposes an example that PTPL can simulate liposarcoma clinically. In addition, both disorders are rarely reported in dermatological journals, which cause a poor knowledge about its clinical resemblances and differences by dermatologists.
