متن کاملThe Spectrum of Spitz Nevi
Main Outcome Measure: Frequency of dermoscopic patterns within the different histopathologic subtypes of Spitz nevi. Results: Overlapping clinical, dermoscopic, and histopathologic findings were observed among PSN, RN, and PSRN, thereby justifying their inclusion into the single PSRN diagnostic category. Asymmetry was the most frequent indicator of histopathologic ASN (79%; n=11); in only 4 cas...
متن کاملMelanoma mimic: a case of multiple pagetoid Spitz nevi.
BACKGROUND Differentiating Spitz nevi from melanoma can be difficult. Pagetoid spread of melanocytes is among the features making diagnosis difficult. Rare reports of isolated pagetoid Spitz nevi exist. OBSERVATIONS We present a unique case of multiple pagetoid Spitz nevi initially diagnosed as multiple in situ melanomas. Germline karyotyping, CDK4 and CDKN2A sequencing, and comparative genom...
