Desmoplastic Melanoma Pathology Outlines

Jan 17, 2006  · A potential diagnostic pitfall in the histologic assessment of melanoma is the inability to recognize unusual melanoma variants. Of these, the more treacherous examples include the desmoplastic.

Desmoplastic melanoma (DM) is a rare melanoma variant that has unique biology and pathology compared with conventional melanoma (non‐DM). Importantly, DM is classified into pure and mixed.

The purposes of pathologic examination of a lesion suspected of being a malignant melanoma are to provide an accurate diagnosis of melanoma (or not), and to provide prognostic information useful in the clinical management of the patient. In the near future, pathologic attributes will also likely be used to predict responses to therapy, as a guide to the selection of specific therapeutic agents.
