Milia are off-white or pearly, superficial lesions that generally measure less than 3 mm in diameter [5]. They are slightly raised above the skin surface.

With regards to the single entities, the following shall be stated:

• Congenital milia may indicate more severe pathologies, e.g., Bazex-Dupré-Christol syndrome, Brooke–Spiegler syndrome, oral-facial-digital syndrome type I, pachyonychia congenita [3] [6]. Accordingly, neonates may present with the respective developmental defects.
• Many neonates develop primary milia not associated with hereditary disorders [3] [7]. There are usually multiple lesions around the nose and in other facial areas, but the neonate's trunk and extremities may also be affected. Spontaneous remission is to be expected.
• Juvenile and adult milia largely resemble those observed in neonates and are very common. However, the condition is usually more persistent and it may take longer until spontaneous remission occurs. Predilection sites are periorbital regions, cheeks, nose, forehead and chest.
• Individuals affected by milia en plaque present with multiple milia grouped on an erythematous plaque [8]. Patients suffering from discoid lupus erythematosus, lichen planus, or pseudoxanthoma elasticum have been suggested to be predisposed to this type of milia. Milia en plaque commonly manifest in the head and neck region, especially in periauricular, periorbital and nose areas.
• Multiple eruptive milia may be diagnosed if patients report the unexplained appearance of crops of milia within a short period of time [9]. Head, neck, and trunk are most frequently affected.

• Outdoor Worker

  Although light appears to play little part in provoking the lesions in the juvenile form, it is certainly implicated in older patients, among whom the incidence is highest in fair-skinned, outdoor workers in sunny climates.[2,9,10,11] Nodular colloid [ncbi.nlm.nih.gov]

• Eruptions

  Multiple eruptive milia may be diagnosed if patients report the unexplained appearance of crops of milia within a short period of time. Head, neck, and trunk are most frequently affected. Milia are diagnosed clinically. [symptoma.com]

  A common method that a dermatologist uses to remove a milium is to nick the skin with a #11 surgical blade and then use a comedone extractor to press the cyst out.[4] See also[edit] Eruptive vellus hair cyst Sebaceous hyperplasia Seborrheic keratosis [en.wikipedia.org]

  Multiple Eruptive Milia Multiple eruptive milia (MEM) is another rare variant in which lesions come up quickly, over the face or the trunk. In some cases, it is associated with other skin syndromes such as the multiple trichoepithelial syndrome. [news-medical.net]

  Multiple eruptive milia Crops of numerous milia appear over a few weeks to months. Lesions may be asymptomatic or itchy. Most often affect the face, upper arms and upper trunk. Traumatic milia Occur at the site of injury as the skin heals. [dermnetnz.org]

• Fussiness

  Amsonia hubrichtii flower reliably year after year, they are not pushy or invasive, are rarely fussy about soil or situation and they are very hardy. [seedaholic.com]

  Your baby may be more irritable or fussy, too. For example, chickenpox may start with tiny red raised spots on the face, but it soon turns into itchy fluid-filled blisters (NHS 2016, NICE 2016a) across the body (NHS 2016). [babycentre.co.uk]

Milia are diagnosed clinically. A small incision into the lesion allows for the expression of keratinous material, which confirms the established visual diagnosis [10]. Although not usually required, tissue samples may be obtained for histopathological analyses. Microscopically, milia correspond to epidermal, keratin-filled cysts delimited by several layers of stratified squamous epithelium. These cysts originate in the infundibulum of the hair follicle. In the case of milia en plaque, immune cell infiltrates can be observed in close proximity to milia [8].

Although little benefit could be seen after the first and second treatments, the patient showed clear improvement after the third treatment. [jamanetwork.com]

Treatment There is no treatment necessary for most cases of milia as they usually clear up on their own. [metrin.com]

Prognosis Colloid milium lesions remain static and do not resolve. Lesions reach their peak within 3 years, after which very few new papules occur. Patient Education Genetic counseling is advisable for the rare juvenile form of colloid milium. [emedicine.medscape.com]

They stated the belief that sunlight is an important factor in the etiology of this condition. [jamanetwork.com]

CONCLUSION: The etiologic significance of this condition is unknown. Potential sources of the material and a discussion of the differential diagnosis follow. [ncbi.nlm.nih.gov]

Although they are very common, evidence regarding their etiology and pathogenesis is scarce. This particularly applies to primary milia, which arise spontaneously. [symptoma.com]

Several etiologies have been postulated including chronic exposure to UV light, contact with petroleum products, application of bleaching creams containing hydroquinone, and genetic predisposition [1]. [escholarship.org]

They can be prevented or minimized with exfoliating like chemical peels, microdermabrasion or topical retinoids. However, they are sometimes difficult to remove without a physician’s help, since they cannot simply be squeezed out. [youtube.com]

Not all cases of milia are preventable, as some people may be more susceptible to them than others. [medicalnewstoday.com]

A milium is a single, superficial, keratin-filled cyst. However, few patients present with solitary lesions and thus, research papers and case reports usually refer to milia. Besides cosmetic issues, milia are benign and not known to be associated with morbidity and mortality. Although they are very common, evidence regarding their etiology and pathogenesis is scarce. This particularly applies to primary milia, which arise spontaneously. In contrast, secondary milia develop after trauma, on sunburned skin, or sites affected by dermatological conditions related to the presence of blisters and bullae. The topical application of corticosteroids has also been related to the onset of milia [1]. Milia have been reported to develop after radiotherapy [2].

The following types of milia may be distinguished:

• Congenital milia
• Neonatal, juvenile, and adult-onset milia
• Milia en plaque
• Multiple eruptive milia
• Trauma-associated milia

Of note, Epstein pearls and Bohn's nodules, i.e., gingival and palatal cysts, display certain similarities to milia and have repeatedly been referred to as the oral counterparts of the cutaneous condition. However, Spanish researchers could not confirm the association between the respective disorders [3] and they should be treated as individual entities [4].
