Sir, My mother is suffering from In Situ Malignant Melanoma in left great toe. One excision has done. The biopsy report says --- In Situ Malignant Melanoma and still some melanocyte are present in the toe. Then I have consulted with a surgeon and he says again a deep excision and skin grafting is required and this the end of the treatment. Because,there is no chemotherapy or radiotherapy of In Situ Malignant Melanoma. Sir,will it be better to cut off the whole toe?
