case_images: Two months prior to this visit, the patient was referred to a dermatologist to have a 1.3 cm diameter-nodule on his right neck removed (Figure 1A) due to cosmetic concerns. The ulcer maintained its size in diameter, but the eschar was darker and concave (Figure 1B) with the depth increased by 0.5 cm. The ulcer was clean, with well-demarcated borders and no signs of infection (Figure 1C). Nineteen days after the initial evaluation, the ulcer had healed, and there were no more signs of infection (Figure 1D).
