Summary
This study reviewed six cases of porokeratosis (PK), a keratinization disorder, identifying three cases each of Mibelli's porokeratosis (MP) and Disseminated Superficial Actinic Prokeratosis (DSAP). While generally favorable, PK prognosis requires monitoring for malignant transformation.
Area of Science:
- Dermatology
- Histopathology
- Keratinization Disorders
Context:
- Porokeratoses (PK) are uncommon dermatoses with unknown pathogenesis.
- Clinical variants include Mibelli's porokeratosis (MP) and Disseminated Superficial Actinic Prokeratosis (DSAP).
- PK presents with characteristic annular plaques and a keratotic border.
Purpose:
- To analyze clinical observations of porokeratosis (PK) over a 16-year period.
- To describe the clinical and histological features of identified PK cases.
- To differentiate between Mibelli's porokeratosis (MP) and Disseminated Superficial Actinic Prokeratosis (DSAP) within the study cohort.
Summary:
- Retrospective analysis of six PK cases (4 female, 2 male; mean age 42.7).
- Three cases of MP and three of DSAP were identified, presenting typical clinical and histological findings.
- MP characterized by large annular plaques; DSAP by numerous small lesions on photo-exposed areas.
Impact:
- Highlights the clinical spectrum and diagnostic features of MP and DSAP.
- Emphasizes the generally favorable prognosis of PK, contingent on monitoring for malignant transformation.
- Underscores the challenges in managing PK and mitigating degeneration risks.

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...

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.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
