Prurigo pigmentosa
Prurigo Pigmentosa
Prurigo Pigmentosa (pronunciation: proo-ri-go pig-men-to-sa) is a rare, chronic inflammatory skin condition characterized by recurrent itchy red bumps that later develop a net-like hyperpigmentation after the inflammation subsides.
Etymology
The term "Prurigo" is derived from the Latin word "prurire", which means "to itch". "Pigmentosa" is derived from the Latin word "pigmentum" meaning "pigment", and the suffix "-osa" indicating "abundance". Thus, the term "Prurigo Pigmentosa" refers to a condition characterized by an abundance of pigment following an itchy rash.
Symptoms
The primary symptom of Prurigo Pigmentosa is the sudden onset of itchy, red bumps or papules that typically appear on the chest, neck, and back. These bumps may later develop into a reticulated or net-like pattern of hyperpigmentation.
Causes
The exact cause of Prurigo Pigmentosa is unknown. However, it has been associated with ketosis, diabetes mellitus, anorexia nervosa, and rapid weight loss.
Diagnosis
Diagnosis of Prurigo Pigmentosa is primarily based on the characteristic clinical presentation and histopathological findings. A skin biopsy may be performed to confirm the diagnosis.
Treatment
Treatment options for Prurigo Pigmentosa include antibiotics such as doxycycline and minocycline, and anti-inflammatory drugs.
Prognosis
The prognosis for Prurigo Pigmentosa is generally good, with most patients experiencing a complete resolution of symptoms with appropriate treatment. However, the condition may recur in some cases.
