Most dermatologists know about the "positive band aid sign." To me, it means a skin cancer has been lurking there for a while.
This 82 yo man came in with a one year history of a "sore" on his back. The drainage stained his shirt. When the band aid was removed, there was a one cm in diameter clean friable tumor, most likely a basal cell.
The lesion was shave biopsied and desicated and curetted. I'll affix a copy of the biopsy report when I get it.
How many of you use the term "Positive band Aid Sign?"
Me, too. Always a sign of a tumor underneath.
