Summary
Terra firma-forme dermatosis presents as dirty, brown-grey skin patches easily removed with alcohol. This condition, linked to abnormal keratinization, is often overlooked by dermatologists.
Area of Science:
- Dermatology
- Pathogenesis of skin conditions
Background:
- Terra firma-forme dermatosis (TFFD) is a distinct skin condition.
- Characterized by 'dirty' brown-grey patches and plaques.
- Often misdiagnosed or overlooked by medical professionals.
Observation:
- Presents with characteristic cutaneous lesions.
- Two cases of TFFD are described in patients with xerosis cutis and atopic dermatitis.
- Clinical presentation and diagnostic challenges are highlighted.
Findings:
- TFFD lesions are easily eradicated with alcohol swabs.
- Pathogenesis is linked to abnormal and delayed keratinization.
- Histological findings resemble dermatosis neglecta, suggesting a potential role of 'neglect' despite adequate hygiene.
Implications:
- Emphasizes the unique clinical presentation and diagnostic criteria for TFFD.
- Suggests further investigation into the role of environmental factors and hygiene in TFFD.
- Highlights the need for increased dermatologist awareness of this treatable condition.

01:11Papillary 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...

01:15Reticular 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.

Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

01:30Skin 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.

01:23Skin 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.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:24Cells 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...

01:05Desmosomes
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...
