Pigmented Spindle Cell Naevus of Reed: A Controversial Diagnostic Entity In Australia

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.
