Here's a list of all the Path programs that didn't fill in the match, with total number of positions available in the match and number of unfilled positions. I did not include any data from programs that were listed as AP- or CP-only. If I'm counting right that makes 17 unfilled positions total, which I believe is lower than average for Pathology.
Penrose Hospital (Colorado Springs, CO) 2 positions, 1 unfilled
Northwestern 5 positions, 2 unfilled
University of Chicago/Northshore 3 positions, 1 unfilled
Berkshire Medical Center (Springfield, MA) 1 position, 1 unfilled
Dartmouth-Hitchcock Medical Center 2 positions, 1 unfilled
Stony Brook 5 positions, 3 unfilled
University of Rochester/Strong Memorial 4 positions, 1 unfilled
Pitt County Memorial Hospital/Brody School of Medicine (Greenville, NC) 3 positions, 2 unfilled
Wake Forest Baptist Medical Center 4 positions, 1 unfilled
West Res Care/NEOUCOM-OH (Youngstown, OH) 1 position, 1 unfilled
