The cohort included seven females and one male with a median age of 39.1 years. Clinical presentations were diverse: one patient had multiple areolar nodules, five presented with breast lumps including three with recurrent lumps, which is an uncommon presentation for DFSP, one had an ulceroproliferative growth with bleeding, and one presented following excision of a recurrent lump elsewhere with histopathology showing positive margins.
