Description

Mal de Meleda: A Rare Skin Disorder

Mal de Meleda, also known as Meleda disease or Mal de Melada, is a rare and inherited skin disorder that affects individuals from early infancy [1]. The primary symptoms of this condition are associated with palmoplantar keratoderma, a type of skin thickening on the palms and soles [2].

Characteristics of Mal de Meleda

The disease is characterized by:

  • Diffuse palmoplantar keratoderma: A condition where the skin on the palms and soles becomes thickened and hardened [3].
  • Scleroatrophy: A type of skin atrophy that leads to a thinning of the skin, particularly on the hands and feet [4].
  • Transient keratoderma: Temporary thickening of the skin on the palms and soles [5].

Inheritance Pattern

Mal de Meleda is inherited in an autosomal recessive pattern, meaning that an individual must inherit two copies of the mutated gene (one from each parent) to develop the condition [6]. This rare genetic disorder affects approximately 1 in 100,000 individuals worldwide [7].

Early Identification

Meleda disease can be identified not long after birth, making early diagnosis and treatment crucial for affected individuals [8].

Signs and Symptoms

Symptoms of Mal De Meleda

Mal De Meleda, also known as Meleda disease, is a rare inherited skin disorder characterized by the development of dry, thick patches of skin on the palms and soles. The primary symptoms of this condition include:

  • Palmoplantar erythema: Redness of the skin on the palms and soles [5]
  • Perioral erythema: Redness around the mouth [7]
  • Symmetric waxy yellowish palmoplantar hyperkeratosis: Thickening of the skin on the palms and soles, which can turn red in color [8]
  • Hyperhidrosis: Excessive sweating on affected skin areas [7]
  • Malodorous maceration: A foul odor from the affected skin areas [8]

Additionally, other features of this disorder may include:

  • Nail abnormalities: Pachyonychia, onycholysis, koilonychia, and brachydactyly (short fingers and toes) [3]
  • Keratoderma: Thickening of the skin on the dorsal surface of the distal phalanges [1]

These symptoms can vary in severity and may be accompanied by other signs of the disease. It's essential to note that there is currently no cure for Mal De Meleda, and treatment focuses on managing the symptoms.

Additional Symptoms

  • Hyperhidrosis
  • Nail abnormalities
  • Palmoplantar erythema
  • Perioral erythema
  • Symmetric waxy yellowish palmoplantar hyperkeratosis
  • Malodorous maceration
  • Keratoderma

Diagnostic Tests

Mal de Meleda, also known as Meleda disease, is a rare hereditary diffuse palmoplantar keratoderma (PPK) with autosomal recessive inheritance.

Diagnostic tests for Mal de Meleda:

  • Multiplex ligation-dependent probe amplification (MLPA): This test can confirm the diagnosis of Mal de Meleda by detecting genetic mutations in the SLURP1 gene [2].
  • Quantitative PCR: This molecular analysis technique is also used to confirm the diagnosis of Mal de Meleda by detecting specific genetic mutations [1].
  • DNA sequencing: Next-generation sequencing and Exomiser can be used to diagnose Mal de Meleda by identifying genetic mutations in the SLURP1 gene [8].
  • Skin biopsy: A thorough clinical exam and skin biopsy are essential for diagnosing palmoplantar keratodermas, including Mal de Meleda. However, molecular analysis is considered the gold standard for confirming the diagnosis [7].

These diagnostic tests can help confirm the presence of Mal de Meleda in individuals with symptoms such as symmetrical and progressive palmoplantar hyperkeratosis.

Additional Diagnostic Tests

  • Skin biopsy
  • DNA sequencing
  • Quantitative PCR
  • MLPA

Treatment

Mal de Meleda, also known as Keratosis palmoplantaris, is a rare genetic disorder characterized by thickening and hardening of the skin on the palms and soles.

Treatment Options

While there is no cure for Mal de Meleda, various treatment options are available to manage its symptoms. According to medical research [1], treatment options include:

  • Topical keratolytic agents: These can help soften and remove thickened skin cells.
  • Propylene glycol: This can be applied topically to help loosen and remove dead skin cells.
  • 5-fluorouracil: A topical cream that can help reduce the thickness of the skin.
  • Surgical treatment: In severe cases, surgical removal of affected skin areas may be necessary.

Oral Retinoids

Research has also explored the use of oral retinoids in treating Mal de Meleda. Studies have shown that:

  • Isotretinoin, acitretin, and alitretinoin can be effective in reducing symptoms [2, 4].
  • Ixekizumab: A biologic medication that has been used to treat the condition, although its effectiveness is still being researched [4].

However, it's essential to note that long-term use of oral retinoids may not be recommended due to potential side effects [7]. Surgical treatment and other topical treatments should also be considered.

Differential Diagnosis

Differential Diagnosis of Mal de Meleda

Mal de Meleda, also known as Meleda disease, is a rare hereditary diffuse palmoplantar keratoderma (PPK) with autosomal recessive inheritance. When diagnosing this condition, it's essential to consider other syndromes that present with similar symptoms.

Differential Diagnosis:

  • Ichthyosis: A group of skin conditions characterized by dry, thickened skin. While ichthyosis can present with palmoplantar keratoderma, the two conditions have distinct clinical and histological patterns [2][3].
  • Psoriasis: An autoimmune condition that causes red, scaly patches on the skin. Psoriasis can also affect the palms and soles, but it typically presents with a more localized distribution than Mal de Meleda [4].
  • Lichen planus: A chronic inflammatory disease that affects the skin and mucous membranes. Lichen planus can present with palmoplantar keratoderma, but it's often associated with other symptoms such as oral lesions and nail changes [5].
  • Mycosis fungoides: A type of cutaneous T-cell lymphoma that can present with a range of skin manifestations, including palmoplantar keratoderma. However, mycosis fungoides is typically associated with more severe systemic symptoms and a poorer prognosis [6].

Key Considerations:

  • Family history: Mal de Meleda is inherited in an autosomal recessive pattern, so a family history of the condition can be a crucial diagnostic clue [7].
  • Clinical and histological patterns: While other conditions may present with similar symptoms, Mal de Meleda has distinct clinical and histological features that can help differentiate it from other syndromes [8].
