Status Final References Source 1: 2007 SEER Manual pgs: C-567 Notes: Appendix C Source 2: ICD-O-3 pgs: Notes: Question MP/H Rules/Histology--Melanoma: Path: Melanoma in situ, lentiginous type, skin rt lower leg. Is this the same as acral lentiginous melanoma (8744)? To code to 8744, do we specifically have to see the word "acral" lentiginous melanoma? Please see discussion. Discussion In researching this, acral lentiginous melanoma is observed on the palms, soles and under the nails. Answer Assign 8742/2 [lentigo maligna] to "melanoma in situ, lentiginous type." Acral lentiginous melanoma is not the same as melanoma, lentiginous type. "Acral lentiginous melanoma," 8744, should be used only if the report states acral lentiginous melanoma or malignant melanoma, acral lentiginous type.
Acral lentiginous melanoma most often occurs on the soles of the feet or the palms of the hands.
