WAIKOLOA, HAWAII – While many pigmented lesions analyzed in the dermatopathology lab are easily classifiable as benign or malignant, a certain percentage of cases are “very challenging to all examiners” – and in those cases, newer testing methods such as immunostaining or genetic testing can provide useful information, according to Dr. Whitney High.
Morphologic analysis of pigmented lesions under the microscope to determine whether a lesion is benign or malignant has limitations, said Dr. High, director of dermatopathology at the University of Colorado at Denver, Aurora. “We don’t really actually know. We haven’t genetically queried the cells.”
In a video interview at the Hawaii Dermatology Seminar, Dr. High emphasized, however, that no test is 100% sensitive and 100% specific. In fact, such tests should be considered adjunctive – requiring “some type of physician oversight or guidance to decide what is a significant result, what is an insignificant result, what is a confounded result, [and] what is a discrepant result.”
Clinical information is also useful, Dr. High said, noting that when this information is not provided, “I don’t really have any feeling from the clinician as to whether the lesion is new, growing, changing, [or] doing anything suspicious.”
