A

Bone Scan

30
Q

Tx for EARLY STAGE Penile CA & PeIN (pre-malig lesion)

A

Organ sparing procedures
* Topical (5-FU, Imiquimod)
* Rad
* Mohs Sx
* Laser Ablation

+/- Inguinal lymph node dissection
+/- ADD Chemo/Rad

32
Q

Tx for Physiologic Phimosis

A
  1. REASSURANCE, self-resolve by 16yo
  2. If does not go away with age -> STEROIDS + STRETCH EXERCISES
