Summary
Erythema nodosum (EN) is a common panniculitis presenting as painful red nodules on the lower extremities. This condition affects the skin and subcutaneous fat, typically appearing symmetrically on the shins.
Area of Science:
- Dermatology
- Pathology
Background:
- Erythema nodosum (EN) is the most frequent type of panniculitis.
- It manifests as painful, red nodules in the skin and subcutaneous tissue.
- These nodules are typically 1-6 cm, rounded or oval, and may merge.
Purpose of the Study:
- To describe the clinical characteristics of Erythema nodosum.
- To detail the typical presentation and location of EN lesions.
Main Methods:
- Clinical description of Erythema nodosum.
- Observation of lesion characteristics and distribution.
Main Results:
- EN presents as slightly raised, nonulcerative, painful red nodules.
- Lesions are often symmetrical and bilateral, commonly on the anterior tibial surface.
- Involvement may extend to ankles, lower thighs, and forearms.
Conclusions:
- Erythema nodosum is a distinct clinical entity within panniculitis.
- Its characteristic presentation aids in diagnosis and understanding its pathology.

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...

01:23Skin 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.

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.

01:15Reticular 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.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

01:25Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
01:26Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
