Routine Pathological Evaluation of Neuroma Specimens: Is There a Rationale?

ABSTRACT

The routine pathological analysis of therapeutically resected traumatic or postoperative neuroma specimens to confirm diagnosis and rule out occult malignancy remains a controversial issue. Some experts advocate histological analysis of all specimens, and others rely on institutional policy. A retrospective chart review of all patients who underwent excision of clinically diagnosed neuroma over a 6-year period at one institution by a single surgeon was initiated. The correlation of preoperative diagnoses with histological analysis and cost of analyzing specimens individually and over the 6-year period was calculated. Of 515 neuromas resected, 100 were sent for pathological review. Every submitted specimen was histologically confirmed to be a traumatic neuroma, and none of the specimens harbored occult malignancy. Ultimately, no treatment plan was altered after final histology was confirmed. The cost to analyze each specimen (Current Procedural Terminology code 88305) was $495, expressed in U.S. dollars. If every specimen was analyzed, a total cost of $254,925 would have be incurred over the 6-year period. Routine pathological analysis of clinically and intraoperatively confirmed neuromas must be questioned in terms of standard of care requirements given its failure to aid in treatment plans as well as its significant cost to health care systems.
