In what circumstances would you recommend adjuvant radiation for a keratocanthoma with SCC after resection?
Would margin status, grade, size, location, LVI, or PNI affect your decision?
Answer from: Radiation Oncologist at Community Practice
KA by itself (in the absence of SCC) is at the interface of benign and malignant. In a pure KA, if margins are negative, no further RT is needed. If there is SCC mixed, as can happen even with BCCs, the adjuvant RT indication rules pertaining to SCC prevail.
