Reticular Dermis

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

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...

Papillary Dermis

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 Diseases and Disorders

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

Skin Cancer

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...

Summary

Cutis laxa, a rare genetic disorder causing loose skin, was diagnosed in a patient via FBLN5 gene study. This confirmed the hereditary condition, aiding prognosis and family genetic counseling.

Area of Science:

Genetics
Dermatology
Rare Diseases

Background:

Cutis laxa is a rare connective tissue disorder affecting elastic fibers, leading to loose, inelastic skin.
It can be inherited or acquired, with congenital forms potentially involving internal organs and worsening prognosis.

Observation:

A case study of a female patient presenting with clinical signs suggestive of hereditary cutis laxa is detailed.
The patient had consanguineous parents (second-degree cousins) and a deceased brother with a similar presentation, indicating a familial pattern.

Findings:

Genetic analysis focusing on the FBLN5 gene was crucial for confirming the diagnosis of cutis laxa.
Identifying the specific gene mutation allowed for a more accurate prognosis determination.

Implications:

This case highlights the importance of genetic testing in diagnosing rare inherited disorders like cutis laxa.
Confirmed genetic diagnosis facilitates precise prognosis and enables informed genetic counseling for affected families.
