case_images: (a) Two erosive surfaces in the lower lip, with central uplift distributed symmetrically left and right. (b) Two ulcers of the same size could be seen at the corresponding part of the front part of the tongue. (c) Fuzzy infiltrating erythema in front and back of the trunk.

case_images: There were two erosive surfaces in the lower lip, with central uplift distributed symmetrically left and right, same size, yellow-red oval shape, about 1 cm in diameter, no secretion on the surface, clear depression at the edge palpable hardness like cartilage (Figure 1a). Two ulcers of the same size could be seen in the anterior part of the tongue, corresponding to the lower lip, which were round with shallow funnelform, central depression, and clean surface (Figure 1b). The patient had fuzzy infiltrating erythema in the front and back of the trunk, which was symmetrical distribution, about the size of soybeans (Figure 1c).
case_images: (a) The erosion surfaces of the patient's lips became softer, smaller and flatter obviously. (b) The erosion surfaces of the patient's tongue became softer, smaller and flatter obviously. (c) The erythema of the trunk completely subsided.

case_images: Seven days later, when the patient received the second benzathine penicillin treatment, the erosion surfaces of the patient's lips and tongue became softer, smaller and flatter obviously (Figure 2a and b), and the erythema of the trunk completely subsided (Figure 2c).
