The patient is a 45 yo woman who presented with a new lesion
on the right malar eminence. It looked
innocuous, perhaps, a lentigo. The dermatoscopic
image revealed a pointillist pattern.
One of our VGRD members, Dr. Phung Huynh described “pointillist nevus”
some years ago. While this is not a
nevus, it shows a similar pattern.
A 3 mm punch biopsy was taken to establish what this lesion is and it is being presented for interest since I could find no reference to this
phenomenon in PubMed.

Pathology: The biopsy shows a focal lichenoid lymphocytic infiltrate, scattered colloid bodies and melanophages consistent with lichen planus-like keratosis (LPLK).
