The FP noted that the patient had a dominant brown patch on her right cheek that was larger and darker than the other light brown spots found on her face. Fortunately, he had a dermatoscope and examined the spot closely, finding only features of a benign solar lentigo. There were no suspicious features for melanoma.
The FP gave the patient a choice between a broad shave biopsy that day, or having the lesion monitored (safe with a flat lesion) using photography and dermoscopy.
The patient didn’t want a biopsy on her face and was willing to have the area monitored. The clinical and dermoscopic photographs were taken and stored. The patient was given a follow-up appointment in 4 to 6 months and instructions to avoid the sun as much as possible. She was also told to use sunscreen and hats when out in the sun.
After 5 months, the previous photos were compared with the new photos on a computer screen and there were no changes. Everyone was reassured, and the patient indicated that she was being careful about her sun exposure.
