[Exulcerated, nodular tumor on the occiput of a 29-year-old patient].

Cranial fasciitis is a rare variation of nodular fasciitis that occurs in the region of the capillitium. We report on a 29-year-old patient who presented with a 2-month history of a tumor progressively increasing in size located on the occiput. Histological examination revealed a tumor, consisting of tightly packed spindle-shaped cells with underlying myxoid stroma, which extended from the dermis to the subcutis. Actin and vimentin were detected by immunohistochemistry. We established a diagnosis of cranial fasciitis and excised the tumor. Especially when a child or young adult presents with a tumor in the skull area, consideration should be given to cranial fasciitis in the differential diagnosis to avoid unnecessary and possibly very invasive treatment approaches.
