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.

Persistent Melanocytic Nevi: A Review and Analysis of 205 cases


Great article in the June 2011 issue of the ‘Journal of Cutaneous Pathology’ regarding persistent melanocytic naevi. Good reading for those interested in the subject.

Things of note are

– female predominance (reason unclear)

– back is the most common site followed by abdomen then chest

– mean time between original biopsy then biopsy of persistent naevus was 9.7 months

– dysplastic naevi were most likely to recur

– persistent melanocytic naevi were more likely to be initially removed via shave biopsy
