Lentigo Maligna (Melanotic Freckle of Hutchinson) with Melanocarcinoma. Presented by Dr. Herbert L. Joseph, Vallejo, Calif.


Dr. George C. Andrews, New York: The lesion is in an area that can be excised and grafted. I think surgical removal is the thing to do.

Dr. Herbert L. Joseph, Vallejo, Calif.: The term "lentigo maligna," as sometimes used in dermatology texts, is confusing. It has been used synonymously with xeroderma pigmentosum. A literal translation would be "malignant lentigo," and I believe we should adhere to this connotation. In other words "lentigo maligna" is simply lentigo which has become malignant. Much of the confusion appears to arise from the use of the term "lentigo." Lentigo should designate the distinctive percancerous hyperpigmented lesion, mostly on the face, arising in elderly persons, to be distinguished from junction nevus, freckle, pigmented basal-cell carcinoma, and senile or seborrheic keratoses.

Histologically lentigo maligna is indistinguishable
