Milia en plaque

Milia en plaque is a rare cutaneous condition characterized by multiple milia that are set on an erythematous base, or plaque. This condition was first described in 1978 and is considered a subtype of primary milia.

Etiology

The exact cause of milia en plaque is unknown. However, it is believed to be associated with damage to the sweat glands or hair follicles. Some studies suggest that it may be related to genetic factors, as it has been observed in families with a history of the condition.

Clinical Features

Milia en plaque typically presents as a plaque of numerous small, white, dome-shaped papules. These papules are milia, which are small cysts filled with keratin. The plaque is usually located on the ears, eyelids, cheeks, or jaw area. The condition is usually asymptomatic, but some patients may experience mild itching or discomfort.

Diagnosis

Diagnosis of milia en plaque is primarily based on clinical examination. The distinctive appearance of the plaque and the presence of milia make it relatively easy to identify. In some cases, a skin biopsy may be performed to confirm the diagnosis and rule out other conditions.

Treatment

Treatment for milia en plaque is not always necessary, as the condition is benign and does not cause serious health problems. However, treatment may be desired for cosmetic reasons or to alleviate any discomfort. Treatment options include topical retinoids, dermabrasion, and laser therapy.

Prognosis

The prognosis for milia en plaque is generally good. The condition does not cause serious health problems and does not affect a person's lifespan. However, it can cause cosmetic concerns and may recur after treatment.
