Macroscopic and imaging findings of this complete regression of cutaneous MM on the right sole associated with right inguinal lymph node metastasis. a, b The patient had a solitary bluish to black patch with surrounding depigmentation, accompanied by recent decrease in size, measuring up to 20 mm in the right sole. In fact, he had noticed it as a gradually growing, hemorrhagic and verrucous hypopigmented macule since approximately 2 years before.
