Brünauer–Fuhs–Siemens (BFS) type of palmoplantar keratoderma is a rare genetic skin disorder that is characterized by thickening and structural changes of the skin on the palms and soles. It is named after three dermatologists; Josef Brünauer, Otto Fuhs and Carl Siemens, who first described the disease in 1932. The condition is caused by a mutation in the GJB2 gene which encodes for Connexin 26 protein. It is an autosomal dominant disorder which means that only one mutated copy of the gene is needed to cause the condition. BFS type of palmoplantar keratoderma can be mild or severe with symptoms ranging from thickening and scaling of palms and soles to painful fissures on feet leading to difficulty in walking. There are currently no known cures for this condition but treatments can help alleviate symptoms. Brünauer–Fuhs–Siemens (BFS) type of palmoplantar keratoderma is a rare disorder of the skin that is characterized by excessive thickening of the palms and soles, resulting in a rough, scaly texture. It is an inherited condition caused by a mutation in the gene GJB2, leading to a deficiency in the protein Connexin 26. This condition affects both males and females equally and can present itself at any age. Symptoms include thickened skin on the palms and soles, fissures on the skin, pain when pressure is applied to affected areas, and an increased risk for bacterial infections. Treatment for BFS type palmoplantar keratoderma focuses on managing symptoms and preventing infections. This includes topical medications such as salicylic acid or urea-based creams to reduce the thickness of the skin lesions. Oral antibiotics can also be prescribed to prevent bacterial infections. Additionally, corticosteroid creams may be used to reduce inflammation and itching. Surgery may be recommended in some cases to remove thickened areas of skin or treat underlying conditions that may be causing pain or discomfort.

Brünauer–Fuhs–Siemens Type Of Palmoplantar Keratoderma Pathology

Brünauer–Fuhs–Siemens type of palmoplantar keratoderma is a rare form of keratoderma, which affects the palms and soles of the feet. It is characterized by thickening and scaling of the skin on the palms and soles. The condition is caused by a genetic mutation that affects the production of an enzyme called transglutaminase 1 (TGM1). This enzyme helps in the cross-linking of proteins in the skin, which results in thickening and scaling. Histopathological examination reveals hyperkeratosis, acanthosis, hypergranulosis, dilated blood vessels, and parakeratotic cells in the epidermis. In addition, there may be hypogranulosis or parakeratotic cells in the stratum corneum. The dermis shows dilated blood vessels and lymphocytes with focal perivascular infiltrate. Treatment for this condition includes topical retinoids, emollients, topical antifungals, and UV light therapy. In severe cases, systemic retinoids or immunosuppressants may be prescribed. Surgery may be necessary to remove large areas of thickened skin in cases where other treatments are not effective.

The clinical manifestations of Brünauer–Fuhs–Siemens type palmoplantar keratoderma vary from person to person but typically include thickened red skin on palms and soles with a pebbly texture. Hyperhidrosis or excessive sweating is also common in affected individuals. The condition may also cause pain or discomfort due to friction between shoes and feet when walking or running. Furthermore, fissuring between toes can occur due to excessive friction from footwear.

Diagnosis is usually made based on clinical examination but can be confirmed by histopathological examination which shows hyperkeratosis with acanthosis and hypergranulosis as well as parakeratotic cells in the epidermis. Dilated blood vessels can be seen in both epidermis and dermis as well as focal perivascular infiltrate consisting of lymphocytes.

Treatment for Brünauer–Fuhs–Siemens type palmoplantar keratoderma includes topical retinoids such as tretinoin or adapalene along with emollients such as petrolatum jelly to help reduce scaling and dryness. Topical antifungals might also be prescribed if there is evidence of fungal infection on physical examination or if a skin scraping reveals fungal hyphae or spores on microscopy. Ultraviolet (UV) light therapy can also be used to reduce symptoms but should only be done under medical supervision.

In severe cases where other treatments are not effective systemic retinoid drugs such as isotretinoin might need to be prescribed along with immunosuppressants such as cyclosporine A for resistant cases. Surgery might also be necessary to remove large areas of thickened skin if necessary.

Treatment for this condition includes topical retinoids along with emollients and antifungals while more severe cases might require systemic medications such as retinoids or immunosuppressants as well as surgery if necessary.

Brünauer–Fuhs–Siemens Type Of Palmoplantar Keratoderma

Palmoplantar keratoderma (PPK) is a disorder of the skin characterized by thickening and hyperkeratosis of the palms and soles. The Brünauer–Fuhs–Siemens type (BFS-PPK) of PPK is an autosomal dominant disorder caused by mutations in the keratin 1 gene (KRT1). BFS-PPK is characterized by diffuse, noninflammatory, symmetrical hyperkeratosis on both palms and soles. It usually presents at birth or in early childhood and persists into adulthood.

The genetic cause of BFS-PPK has been identified as mutations in the KRT1 gene located on chromosome 17q21. The KRT1 gene encodes for the production of keratin 1, a structural protein found in the outermost layer of skin cells called the stratum corneum. Mutations in this gene can lead to increased production of keratin 1, resulting in increased skin cell thickness and hyperkeratosis.

The clinical manifestation of BFS-PPK varies from patient to patient, with some patients having mild symptoms while others have more severe symptoms. The most common symptom is thickening and hyperkeratosis of the palms and soles. Other symptoms may include itching, redness, scaling, cracking and fissuring, as well as pain when walking or standing. Additionally, some patients may have nail abnormalities such as brittleness or pitting of nails.

In terms of treatment options for BFS-PPK, there are several available therapies that can help to alleviate symptoms and improve quality of life. Topical medications such as urea creams or salicylic acid ointments can be used to reduce thickening and soften skin on affected areas. Additionally, systemic medications such as retinoids or methotrexate can be used to reduce inflammation associated with PPK. In more severe cases surgery may also be an option to remove excess tissue from affected areas or to correct any underlying bone deformities caused by the condition.

, Brünauer–Fuhs–Siemens type (BFS-PPK) is an autosomal dominant disorder caused by mutations in the KRT1 gene located on chromosome 17q21 that results in diffuse noninflammatory symmetrical hyperkeratosis on palms and soles.

Differential Diagnosis of Brünauer–Fuhs–Siemens Type Of Palmoplantar Keratoderma

The differential diagnosis of Brünauer–Fuhs–Siemens type of palmoplantar keratoderma includes:

• Epidermolytic palmoplantar keratoderma: This is a genetic form of keratoderma that is characterized by thickened skin on the palms and soles. It is usually associated with mutations in the genes that encode proteins involved in the formation of the epidermis.

• Keratoderma Claviforme: This is a rare form of keratoderma that presents with thickened skin on the palms and soles. It is caused by mutations in several different genes, such as those involved in cell adhesion.

• Keratosis Follicularis Spinulosa Decalvans: This is an inherited disorder that presents with thickened skin on the scalp, face, and palms and soles. It is caused by mutations in a gene known as KRT10.

• Ichthyosis Vulgaris: This is a common form of inherited skin disorder that results in dry, scaly skin on the hands, feet, torso, and face. It is caused by mutations in several different genes.

• Darier’s Disease: This is a rare autosomal dominant genetic disorder caused by mutations in the ATP2A2 gene. It presents with thickened skin on the palms and soles as well as other areas of the body such as scalp, face, chest, back, and neck.

• Hailey-Hailey Disease: This is an autosomal dominant disorder caused by mutations in ATP2C1 gene. It presents with vesicles or blisters on the neck, chest, underarms and groin area as well as thickening of the palms and soles.

All these conditions present with similar clinical features but can be distinguished based on their underlying genetics or other associated symptoms such as vesicles or blisters which are typically seen in Hailey-Hailey disease but not in Brünauer–Fuhs–Siemens type of palmoplantar keratoderma. Additionally, treatment strategies differ between these conditions and thus it is important to make an accurate diagnosis to ensure optimal management for better patient outcomes.
