History of Present Illness
This is a 26-year-old white male who was referred to the Department of Oral and Maxillofacial Surgery at the University of Washington for evaluation of a pigmented lesion(s) on the left anterior mandibular labial gingiva. The patient reported that the lesion had been there for three years and had been closely observed by his dentist, who noticed that it was changing in character and size and immediately referred him to Dr. Beirne for a biopsy and evaluation. The patient was concerned and reported noticing this lesion about three years ago. He believed it had been growing, saying it was "20 times bigger." He reported occasional and very mild pain in the area which may or may not have been related to the pigmented lesion(s). Under local anesthesia, an incisional biopsy of the most pigmented area was performed.
