Transient melanoma progression in a patient treated in Cohort A, accompanied by vitiligo. a This patient developed the onset of vitiligo and greying hair after receiving four cycles of Melanoma GVAX. Vitiligo was initially confined to a prior lymphadenectomy incision site, but progressed to other skin sites and hair over the next few months. b Pelvic CT scan at the 6-month evaluation interval showed enlarging left pelvic lymph nodes (yellow and red arrows), biopsy-proven to be recurrent melanoma. At 8 months, these lesions had regressed without further intervention. Two months later, they enlarged again and the patient went on to receive other therapies.
