2 colors, 1 diagnosis

A 45-year-old woman was referred for this pigmented lesion with 2 colors.

Diagnosis was easy with dermoscopy:

• comedo-like openings 
• milia-like cysts
• fissures and ridges 
• network-like structures
• sharp demarcation

in favor of a seborrheic keratosis

Fat fingers

Typical presentation of a seborrheic keratosis with network like structures and fat fingers.

In this case there are no other signs of seborrheic keratosis (milia-like cysts, comedo-like openings, fingerprint-like structures, hairpin blood vessels)

Network-like structures

This patient presented a seborrheic keratosis with a fissure-like pattern and network-like structures. On the 3rd picture there are thicker-branched and dark-brown segments.
