Gudrun I work in a dermatopathology lab, and we don't see any issues leaving our specimens in 10% NBF for days at a time. We don't work on the weekends, so any specimens that are grossed remain on our processors in NBF from Friday at 8:00 PM until about 5:30 PM on Sunday. I also agree with Kris that 4 hours of fixation is not long enough to ensure proper fixation unless they are shave biopsies.
