Dermatosis papulosa nigra
Dermatosis Papulosa Nigra (pronunciation: der-muh-TOE-sis pap-yuh-LOH-suh NYE-gruh) is a common dermatological condition characterized by multiple, small, hyperpigmented, asymptomatic papules on the face and neck. The term is derived from the Greek words derma meaning skin, papulosa meaning papule, and nigra meaning black.
Definition
Dermatosis Papulosa Nigra (DPN) is a benign skin condition common among individuals of African descent. It is characterized by small, dark, raised spots that appear on the skin. These spots, or papules, are often found on the face and neck.
Symptoms
The primary symptom of DPN is the presence of small, dark, raised spots on the skin. These spots are typically 1-5mm in diameter and can vary in color from brown to black. They are most commonly found on the face and neck, but can also appear on the chest and back.
Causes
The exact cause of DPN is unknown. However, it is believed to be genetic in nature, as it is more common in individuals of African descent and often runs in families. Some studies suggest that it may be related to an increase in the production of melanin, the pigment that gives skin its color.
Treatment
Treatment for DPN is typically not necessary, as the condition is benign and does not cause any physical discomfort. However, some individuals may choose to have the papules removed for cosmetic reasons. This can be done through various methods, including cryotherapy, electrosurgery, and laser therapy.
