Acne necrotica is a relatively rare dermatological condition characterized by the development of inflamed and itchy lesions on the scalp. It is considered a severe form of folliculitis that leads to the death of hair follicles.
The term "acne necrotica" is derived from the Latin word "acne," meaning skin eruption or pimple, and "necrotica," referring to necrosis, or tissue death. This condition primarily affects the scalp, but can also appear on the face, neck, and back.
The exact cause of acne necrotica is still uncertain. However, it is believed to be associated with various factors, including bacterial or fungal infections, immune system dysfunction, underlying genetic predisposition, or hormonal imbalances. It is often considered a more severe variant of scalp folliculitis or acne keloidalis nuchae.
Clinically, acne necrotica typically presents as small, painful, and itchy pustules or papules on the scalp. As the condition progresses, the affected hair follicles become necrotic, leading to the formation of crusts, scabs, or plaques.
Treatment options for acne necrotica may include topical or systemic medications such as antibiotics, antifungals, corticosteroids, or retinoids. Additionally, proper scalp hygiene and avoiding trauma to the affected areas are important in managing this condition.
In summary, acne necrotica is a rare and severe form of folliculitis that affects the scalp and can lead to the death of hair follicles. Prompt diagnosis and treatment are crucial to prevent complications and promote healing.
