Summary
Erythrokeratodermia variabilis (EKV) is a rare skin disorder. This study highlights two cases, with one showing significant improvement using oral retinoids, suggesting their efficacy in managing EKV symptoms.
Area of Science:
- Dermatology
- Genetics
- Rare Diseases
Background:
- Erythrokeratodermia variabilis (EKV) is a rare genodermatosis characterized by keratinization disorders.
- Mutations in connexin 31 and 30.3 genes on chromosome 1 p34-35 are associated with EKV.
- This report details two pediatric cases of EKV.
Observation:
- Case 1: A 15-month-old boy presented with hyperkeratotic plaques on extremities, axillae, and face since 6 months of age.
- Histopathology revealed acanthosis, papillomatosis, and orthokeratotic hyperkeratosis.
- Case 2: A 10-year-old girl presented with fixed hyperkeratotic plaques and transient erythematous patches since 1 month of age.
Findings:
- Anatomoclinical comparison confirmed EKV in both patients.
- The second patient experienced dramatic improvement within 2 weeks of treatment with acitretin (an oral retinoid).
- EKV is defined by fixed plaques and transient erythematous patches; histopathology is supportive but not definitive.
Implications:
- A typical physical examination and compatible histopathology aid EKV diagnosis.
- Oral retinoids demonstrate rapid effectiveness in managing EKV.
- This study underscores the therapeutic potential of oral retinoids for EKV management.

Disorders of Erythrocytes
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.

Reticular Dermis
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Papillary Dermis
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
