Agree with lichen aureus as suggested by Dr Abdul Kadir but why this lesion was removed with a margin exam????

[font=arial,helvetica,sans-serif][size=4]Lichenoid pigmented purpura of Gougerot and Blum, which corresponds to early (= extravasated erythrocytes) lichen aureus (= hemosiderin deposition).
Trying to respond to Mona’s query, maybe the dark color of the lesion made the clinician assume this could be a melanocytic tumor.[/size][/font]

My diagnosis was lichen aureus. The reason it was excised was because it was thought to be a neoplasm. There was no specific neoplasm considered clinically, however.
