Soft tissue lesions of the penile corporeal bodies are rare and usuall
y represent benign or malignant tumors, or Peyronie's disease. We repo
rt a unique case of a deep seated penile mass that at exploration prov
ed to be an encapsulated hematoma of the inter-corporeal septum. Preop
erative diagnosis of lesions of the corporeal bodies is facilitated by
high resolution Doppler ultrasonography. Surgical exploration to excl
ude malignancy must be done unless the clinical and/or radiographic fi
ndings are unequivocally benign (Peyronie's plaque, simple cyst and so
forth). Surgical exploration must be done according to the penile neu
rovascular anatomy to preserve potency and glanular sensation.
