Melanoma or more...
A 65 year old male came to Krishna Hospital
with C/O non healing ulcer on right heel for 5 months and pain over ulcer.
Patient was apparently admitted seven months back, then he developed a swelling over right heel which gradually increased in size and was painful.The patient visited a private hospital for the swelling and was given some surgical intervention but was not relieved. Then patient came to KIMS hospital since 8 months and was done wide excision plus STSG decreased GA. He got relieved and after 2-3 months again swelling grew near the previous one and ulcerated for which he underwent regular dressing and antibiotics.
What could be the differential diagnosis and further line of treatment?
