This case involves a 52-year-old female patient who regularly saw a dermatologist. The defendant dermatologist noted an abnormal finding on the patient’s cheek. Although the dermatologist noted the finding in the patient’s records, he failed to ever biopsy it. The patient visited a cancer center two and a half years after the original detection of the abnormal finding. The area was biopsied and the patient was diagnosed with advanced stage melanoma. A dermatologist with expertise in skin cancer was sought to opine on what effect a delay in the diagnosis of this length might have on a patient’s melanoma prognosis.
