Summary
This study reports a family with Thost-Unna keratoderma and epidermolytic hyperkeratosis. Treatment with oral aromatic retinoids improved skin but caused erosions, necessitating discontinuation.
Area of Science:
- Dermatology
- Genetics
- Histopathology
Background:
- Thost-Unna keratoderma is a rare inherited skin disorder.
- Epidermolytic hyperkeratosis is a condition characterized by abnormal keratinization.
- The association between these two conditions is not fully understood.
Observation:
- Three family members presented with Thost-Unna keratoderma and epidermolytic hyperkeratosis.
- Literature review included cases of keratoderma with similar histopathological findings.
- Treatment with oral aromatic retinoids initially improved hyperkeratosis.
Findings:
- Aromatic retinoid treatment led to skin erosions and discomfort, requiring discontinuation.
- The study highlights the potential for adverse effects even with improved hyperkeratosis.
- Histopathological examination is crucial for accurate diagnosis.
Implications:
- Increased recognition of the association between keratoderma and epidermolytic hyperkeratosis is needed.
- Careful monitoring is essential during retinoid therapy for such conditions.
- Further research may elucidate optimal treatment strategies for this specific dermatosis.

Desmosomes
The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed during the late 1800s and described as small, dense nodules in the epidermis. Desmosomes are button-like structures that help form an interlinked network of intermediate filaments across the cells. These junctions are essential to hold cells together under mechanical stress and to maintain tissue integrity. Desmosomes are multi-protein complexes comprising desmosomal...
Renewal of Skin Epidermal Stem Cells
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...
Clinical Applications of Epidermal Stem Cells
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
Cells of the Epidermis
The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...

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...

Layers of the Epidermis
The epidermis, the outermost layer of the skin, is composed of several distinct layers. From deep to superficial, the layers of the epidermis are as follows:
Stratum Basale
Stratum basale, also known as the stratum germinativum, is the deepest layer of the epidermis. It is composed of a single layer of actively dividing cells called basal cells or basal keratinocytes. These cells constantly undergo cell division to replenish the upper layers of the epidermis. Additionally, melanocytes, which...
