What is the difference between melasma and chloasma?

Melasma is a common, harmless skin problem that causes dark patches (hyperpigmentation) on your face. It's usually caused by sun exposure. When melasma appears in pregnant women, it's referred to as chloasma, or “the mask of pregnancy.” Chloasma is triggered by hormonal changes that occur during pregnancy.

Board-certified dermatologists have the expertise required to give you an accurate diagnosis and individualized treatment plan.

What is hypopigmentation on face?

Hypopigmentation is a low amount of melanin in your skin. Patches of your skin are lighter in color than your surrounding skin. Your skin, hair and eyes get their color from a chemical called melanin. When your skin cells don't make enough melanin, areas of your skin become lighter.

The two major forms are men1 and men2 with gene mutations on chromosome 11 and chromosome 10, respectively. An autosomal dominant inherited neoplastic syndrome characterized by the development of various endocrine neoplasms and abnormalities in various anatomic sites.

What is polyglandular adenomatosis?

Clinical Information. A group of autosomal dominant diseases characterized by the combined occurrence of tumors involving two or more endocrine glands that secrete peptide hormones or amines. These neoplasias are often benign but can be malignant.

Epidemiology

Exact prevalence and incidence rates for Noonan syndrome with multiple lentigines (NSML) are not known. About 300 cases have been described to date. A slight male predominance has been reported.

Clinical description

Patients with NSML have a characteristic facial appearance including a broad forehead, hypertelorism, ptosis, down-slanting palpebral fissures, a high-arched palate, and low-set posteriorly rotated ears. Pectus deformity is common.

Etiology

NSML is mainly caused by mutations in the PTPN11 gene (12q24.1). Mutations are different from those known to cause Noonan syndrome, explaining the distinct clinical phenotype. Some cases are reported to involve mutations in RAF1 (3p25) , BRAF (7q34), or MAP2K1 (15q22.1-q22.33; one patient). There may be other currently unidentified causative genes.

Diagnostic methods

Clinical diagnosis may be difficult because of the absence of characteristic lentigines. Patients may have an initial diagnosis of Noonan syndrome. Molecular genetic testing may be useful to confirm diagnosis or to distinguish between overlapping syndromes.

Differential diagnosis

The clinical presentation overlaps significantly with Noonan syndrome and the main distinguishing manifestation is multiple lentigines. Other differential diagnoses include cardio-facio-cutaneous, Costello, and Turner syndromes.

Antenatal diagnosis

Prenatal diagnosis is possible if a causative gene mutation has been identified in an affected family member.

Genetic counseling

NSML follows an autosomal dominant pattern of inheritance. The proportion of de novo mutations is unknown. Genetic counseling should be provided to affected families informing them that there is a 50% risk of transmission from an affected individual to their offspring.

What is the second highest occurring symptom after lentigines?

Ocular hypertelorism: Wideset eyes, which lead to a similar facial resemblance between patients. Facial abnormalities are the second highest occurring symptom after the lentigines. Abnormalities also include: broad nasal root, prognathism (protruding lower jaw), or low-set, possibly rotated, ears.

How to treat lentigines?

Other management is routine care as symptoms present: 1 For those with endocrine issues (low levels of thyrotopin [a pituitary hormone responsible for regulating thyroid hormones], follicle stimulating hormone) drug therapy is recommended. 2 For those who are disturbed by the appearance of lentigines, cryosurgery may be beneficial. Due to the large number of lentigines this may prove time-consuming. An alternative treatment with tretinoin or hydroquinone creams may help. 3 Drug therapies for those with cardiac abnormalities, as those abnormalities become severe enough to warrant the use of these therapies. ECG's are mandatory prior to any surgical interventions, due to possible arrythmia.

What is the name of the gene that causes the NSML?

Noonan syndrome with multiple lentigines ( NSML) which is part of a group called Ras / MAPK pathway syndromes, is a rare autosomal dominant, multisystem disease caused by a mutation in the protein tyrosine phosphatase, non-receptor type 11 gene ( PTPN11 ). The disease is a complex of features, mostly involving the skin, ...

How common is noonan syndrome?

Noonan syndrome is fairly common (1:1,000 to 1:2,500 live births), and neurofibromatosis 1 (which was once thought to be related to NSML) is also common (1:3500); however, no epidemiological data exists for NSML.

What is the chance of having a child with autosomal dominant syndrome?

As an autosomal dominant trait there is a fifty percent chance with each child that they will also be born with the syndrome. Although fully penetrant, since the syndrome has variable expressivity, one generation may have a mild expression of the syndrome, while the next may be profoundly affected.

What is Noonan syndrome with multiple lentigines?

Noonan syndrome with multiple lentigines (NSML), formerly known as LEOPARD syndrome, is a very rare inherited disorder that is characterised by skin, heart, ear, genital, head and facial abnormalities. It is one of a group of syndromes collectively known as RASopathies .

What mutations are present in noonan syndrome?

Approximately 75% of patients with Noonan syndrome with multiple lentigines carry mutations in the PTPN11 gene ( protein -tyrosine phosphatase, nonreceptor type 11). Ten percent have mutations in the RAF1 gene. In rare cases, mutations in BRAF and MAP2K1 genes are implicated.

What are the non-cutaneous features of noonan syndrome?

Hyperelastic skin (stretchy skin) Non- cutaneous features of Noonan syndrome with multiple lentigines include: Hearing loss in about 25% of patients. Short stature in about 1/3 of patients. Mild degree of mental retardation in about 30% of patients.

What is noonan syndrome?

Noonan syndrome and Noonan syndrome with multiple lentigines are classed as RASopathies. They are due to mutations in genes associated with the RAS/ MAPK cell signalling pathway. These mutations lead to dysregulation of cell division and differentiation.

Is noonan syndrome a lentigine?

Noonan syndrome with multiple lentigines is similar to the condition Noonan syndrome, with the two syndromes being difficult to discern from one another in early childhood. The characteristic dermatological features of each variant develop from later childhood to early teens. The clinical features of Noonan syndrome with multiple lentigines vary ...

Do lentigines have borders?

However, they do not have to be present to diagnose the syndrome. The lentigines are small, dark pigmented flat or slightly raised lesions with well defined borders.

Can noonan syndrome be severe?

The signs and symptoms experienced by people with Noonan syndrome with multiple lentigines vary greatly. Some patients may have a partial form of the syndrome and suffer mild symptoms while others with the full syndrome are more severely affected.

Overview

History

Zeisler and Becker first described a syndrome with multiple lentigines, hypertelorism, pectus carinatum (protruding breastbone) and prognathism (protrusion of lower jaw) in 1936. Sporadic descriptions were added through the years. In 1962, cardiac abnormalities and short stature were first associated with the condition. In 1966, three familial cases were added, a mother, her son and daughter. Another case of mother to two separate children, with different paternity of the tw…

Signs and symptoms

An alternative name of the condition, LEOPARD syndrome, is a mnemonic, originally coined in 1969, as the condition is characterized by some of the following seven conditions, the first letters of which spell LEOPARD, along with the characteristic "freckling" of the skin, caused by the lentigines that is reminiscent of the large cat.
• Lentigines — Reddish-brown to dark brown macules (surface skin lesion) generally occurring in a …

Pathophysiology

In the two predominant mutations of NSML (Y279C and T468M) the mutations cause a loss of catalytic activity of the SHP2 protein (the gene product of the PTPN11 gene), which is a previously unrecognized behavior for this class of mutations. This interferes with growth factor and related signalling. While further research confirms this mechanism, additional research is needed to de…

Diagnosis

The presence of the disease can be confirmed with a genetic test. In a study of 10 infants with clinical indications of NSML prior to their first birthday, 8 (80%) patients were confirmed to have the suspected mutation. An additional patient with the suspected mutation was subsequently found to have NF1, following evaluation of the mother.
There are 5 identified allelic variants responsible for NSML. Y279C, T468M, A461T, G464A, and Q51…

Treatment

It is suggested that, once diagnosed, individuals be routinely followed by a cardiologist, endocrinologist, dermatologist, and other appropriate specialties as symptoms present.
It is recommended that those with the syndrome who are capable of having children seek genetic counseling before deciding to have children. As the syndrome presents frequently as a forme fruste (incomplete, or unusual form) variant, an examination of all family members must be und…

Prognosis

In itself, NSML is not a life-threatening diagnosis, most people diagnosed with the condition live normal lives. Obstructive cardiomyopathy and other pathologic findings involving the cardiovascular system may be a cause of death in those whose cardiac deformities are profound.

Epidemiology

Various literature describes the syndrome as being "rare" or "extremely rare". There is no epidemiologic data available regarding how many individuals have the syndrome worldwide; however, there are approximately 200 cases described in medical literature.
