Let's talk a little aesthetics shall we?
Have you ever seen these before?
Of course you have. It's so common in blacks that as you're reading this you might find one or two on your face or neck.

Dermatosis Papulosa nigra (DPN) and Seborrheic keratosis
These are just benign harmless lesions that are more of a cosmetic embarrassment than anything else. It has been noted to have a familial tendency so it is not uncommon to find it clustered in members if the same family.
DPNs are believed to be a subtype of Seborrheic keratosis which tends to appear flatter. Commonly affected sites include the face, neck, trunk and arms. Usually increases in number with age. May become more extensive with pregnancy.
The cause is not known.

Treatment would involve procedures such as curettage, cryotherapy, electrocautery or even LASER. Be not fooled out there when you are prescribed 'miracle creams' that will take them off. Some of the stuck on ones can fall off on their own.
Removal of these lesions does not prevent recurrence. It is important to tell your patients that. They're lesions that you remove as they appear. Or you can decide to leave alone. We all know the Hollywood actor that this adds to his appeal 😊
To my colleagues...it should be noted that the Leser Trelat sign should be considered as a paraneoplastic syndrome when you see an extensive and rapid evolution of Seborrheic keratosis on the trunk. May be associated with adenocarcinoma of the GIT.
