A positive surgical margin associated with an extraprostatic extension of prostate carcinoma is a significant risk for disease progression. What, then, is the risk of a positive margin created by an inadvertent surgical incision into cancerous prostate parenchyma?


In our daily practice there are several situations in which positive surgical margins are questioned. The first is a positive margin that has resulted because a tumor extending outside the prostate reaching the inked periprostatic tissue margin. A second situation is a positive margin created by an accidental surgical incision into cancerous prostate parenchyma. The third is an equivocal “positive” margin created when the surface of the pathology specimen had a disrupted appearance and the tumor reached the inked edge of the prostate. The third incidence may occur in association with either of the first two situations.
