Giant cell fibroblastoma (GCF) is an uncommon fibroblastic tumor of childhood. Appearing as superficial, poorly circumscribed masses, they are characterized histologically by a mixture of cellular and angiectoid areas with empty cleft-like spaces, lined by spindle-shaped and multinucleated giant cells. We present a case of an 11-month-old boy with penile GCF treated with local excision. The patient presented with a recurrent penile mass 1 year later and underwent repeat excision. Pathologic examination confirmed recurrent GCF. GCF is a benign, but locally recurrent tumor, as demonstrated by our case. To our knowledge, no cases of penile involvement have been previously reported.
