Interesting article in the May 2011 edition of the Australasian Journal of Dermatology by Scott Webber, Greg Siller and Peter Soyer entitled ‘Pigmented Spindle Cell Naevus of Reed: A Controversial Diagnostic Entity In Australia.’
Points of note include
– Pigmented spindle cell naevus of Reed (PSCN) is a recognized distinctly separate entity away from Spitz naevus.
– The clinical and dermatoscopic features of Spitz naevi and melanoma overlap with PSCN.
– Clinical diagnosing of PSCN by dermatology training groups remains difficult.
– Well defined dermatoscopic and physical criteria for lesional morphology and histopathological characteristics are available and have increased the accuracy in distinguishing PSCN from Spitz naevi and melanoma.
– An accurate diagnosis is best gained from clinicopathological correlation.
– PSCN typically occurs in young women, only 25% of cases in patients > 30 years old.
– Punch biopsy as initial management is not recommended as misdiagnosis as melanoma is more likely.
I recommend reading the entire article. Below is a link.
