ANSWER
For a number of reasons (discussed more fully below), the correct answer is to follow up with the pathologist (choice “c”); the biopsying provider, who is the only person to have seen the lesion, is responsible for resolving any discordance between the report and the clinical presentation/appearance.
Simply accepting the report as fact and notifying the patient of the result (choice “a”) is unacceptable. Removing more tissue from the base of the site (choice “b”) is not likely to provide any useful clinical information. Watching the site for change (choice “d”) ignores the possibility that the original lesion has already spread.
DISCUSSION
Skin tags, also known as fibroepithelioma or acrochorda, are extremely common, benign lesions encountered daily by almost all medical providers. Melanoma in tag form is decidedly unusual, but far from unknown. Around 80% of melanomas are essentially flat (macular), and about 10% are nodular. The rest, from a morphologic standpoint, are all over the map. They can be red, blue, and even white. Contrary to popular misconception, they rarely itch, and you probably wouldn’t want to depend on your dog to alert you to their presence.
My point? Although we conceive of melanomas as looking a certain way (a useful and necessary view), the reality is that their morphologic presentations are astonishingly diverse. They include pedunculated tags.
This means that unless we have a very good reason to do otherwise, we should send almost every skin lesion we remove for pathologic examination. Simple, small tags, warts, and the like can be safely discarded. But anything of substance, or anything that appears to be the least bit odd, must be submitted to pathology.
Furthermore, the pathology reports must be carefully read and the results connected to the particular lesion. This case illustrates that necessity nicely. With its black tip, this lesion was more than a little worrisome. When no mention was made of the pigmentary changes, a call to the pathologist was in order.
In this case, the pathologist was more than happy to order new and deeper cuts to be made in the specimen. Within two days, he issued a new report, which showed benign nevoid changes that explained the dark pigment and failed to show any atypia. Then, and only then, were we able to give the results to the patient.
This principle can be extrapolated to results from other types of tests. They are not to be accepted blindly by the ordering provider, who is in the unique position of having seen the patient.
