The minor initially was inconspicuous and then gradually enlarged with painless ulceration in its center [Figure 1b]. Three months later, she developed three nontender new nodules on her right arm, proximal to the initial ulcerated nodule. Her general condition was good. Skin examination revealed a 4 cm × 4 cm tumor, with central ulceration and raised margins. Three diameters in 3-5 cm,展开更多
