Papillary Dermis01:11

Papillary Dermis

6.2K
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...

Skin Cancer

6.3K
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...

Reticular Dermis01:15

Reticular Dermis

5.1K
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...

Skin Diseases and Disorders

5.8K
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...

Summary
This summary is machine-generated.

Ultrasound effectively identifies dermatofibromas, common skin lesions, by revealing their dermal location, subcutaneous extension, and characteristic ill-defined, spiculated margins. These sonographic findings correlate with pathology, aiding diagnosis.

Area of Science:

  • Dermatology
  • Radiology
  • Pathology

Background:

  • Ultrasound is increasingly utilized for superficial soft tissue lesion evaluation.
  • Dermatofibroma is a prevalent dermal lesion with accumulated ultrasound experience.
  • This study focuses on the diagnostic utility of ultrasound for dermatofibromas.

Purpose of the Study:

  • To analyze sonographic features of dermatofibromas.
  • To correlate ultrasound findings with histopathological results.
  • To enhance the diagnostic accuracy of ultrasound in identifying dermatofibromas.

Main Methods:

  • 18 dermatofibromas in 15 patients were examined using ultrasound.
  • Sonographic parameters included location, size, shape, margin, echogenicity, and vascularity.
  • Correlation of ultrasound findings with histopathology was performed by expert consensus.

Main Results:

  • All lesions were dermal, with 78% extending into the subcutaneous layer.
  • Characteristic ultrasound findings included ill-defined margins (83%), spiculated margins (67%), adjacent echogenicity changes (78%), and avascularity (78%).
  • Histopathology confirmed correlations between depth, margin, and spiculation with sonographic observations.

Conclusions:

  • Ultrasound typically visualizes dermatofibromas as avascular dermal lesions with subcutaneous extension.
  • Key sonographic indicators are ill-defined margins, marginal spiculation, and altered echogenicity of surrounding tissues.
  • These findings support ultrasound as a valuable tool for dermatofibroma assessment.
