Colloidal milium: the main types of the disease

Colloid milium belongs to a group of rare degenerative skin deposits. Colloid degeneration disorders are characterized by amorphous, hyaline-like deposits in the dermis, which are classically presented as yellow-brown, translucent papules and plaques in areas exposed to the sun.

Colloid milium can occur at any age, does not tend to resolve itself, and therefore usually requires treatment. On estet-portal.com read why colloid milia occurand how they are treated.

Colloid milium: the main types of the disease

Currently there are 5 different subtypes of colloidal milium:

• Adult colloidal milium;
• Juvenile colloidal milium;
• Pigmented colloidal milium;
• Nodular colloid degeneration (paracolloid) of the skin;
• Acral keratosis with eosinophilic skin deposits.

Colloidal milium is also known as colloidal degeneration, colloidal infiltration, hyaloma, and colloidal colloidal conglomerate.

 

 

Adult colloidal milia is the most common subtype and usually develops in fair-skinned men aged 30-60 who work outdoors, such as in agriculture. In men, four times more often than women, adult colloidal milium develops.

Juvenile colloidal milia is extremely rare at 10-20 years of age, but occurs in children as young as 4 years of age. Familial cases of juvenile colloid milium with autosomal recessive inheritance have been reported.

Pigmented colloidal milium usually follows the use of hydrochynon whitening creams and intense sun exposure. What are the causes of colloidal milium

Adult colloidal milia

 is associated with exposure to excessive sunlight, petroleum products, and chemical fertilizers, although its pathogenesis remains unclear. Sunlight is thought to break down elastin fibers, leading to the accumulation of proteins and fibroblast products in the dermis.

Adult Colloidal Milia:

usually present as numerous translucent flesh-colored or yellow-brown, dome-shaped papules 1–4 mm in diameter;

papules may coalesce into plaques;

Topical retinoids (tretinoin, isotretinoin, adapalene);

Keratolytic creams (urea, salicylic acid, alpha hydroxy acids);

Physiotherapy;

• Curettage and electrosurgery;
• Cryotherapy;
• Dermabrasion;
• CO2 or erbium laser resurfacing;
• Photodynamic therapy.
Excessive cauterization, cryotherapy, and laser therapy can lead to poor cosmetic results.
Colloidal milium may 
• become more extensive
over time, but tends 

to stabilize after three years

. New lesions rarely develop after this period. However, without treatment, 

colloidal milium does not resolve itself
