Two cases of desmoplastic malignant melanoma are described, bringing the total reported to nine. The first developed in a lentigo maligna melanoma and contains the seed of its local recurrence in the primary lesion. The second developed in a clinically apparent congenital nevus and unites the histologic features of the desmoplastic variant with the epithelioid and spindle cell histology of its primary, side by side in a local recurrence. Both primaries were clinically recognized pigmented lesions while the desmoplastic recurrences were amelanotic. Other clinico‐pathologic characteristics of DMM as previously described, are confirmed. Light microscopic evidence is presented supporting the view that the desmoplastic reaction is a rare manifestation elicited by a highly invasive spindle cell component of malignant melanoma.
