The "negative pigment network" is a dermoscopic feature observed in melanomas, melanocytic nevi, and dermatofibromas; however, studies indicate that it is more frequently associated with melanoma. The aim of this case report is to highlight the negative pigment network as an important clue in the diagnosis of melanoma and that its presence, even in the absence of other typical dermoscopic features of melanoma, should prompt further investigation followed by biopsy to confirm the diagnosis.
