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 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...

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...

Summary

Acral melanoma, common in non-Caucasians, requires careful diagnosis. Dermoscopy aids in differentiating melanoma from benign lesions using patterns like the parallel ridge, though its interpretation needs clinical context.

Area of Science:

Dermatology
Oncology

Background:

Acral melanoma is the most common melanoma type in non-Caucasian individuals.
Early diagnosis and differentiation from benign lesions are crucial.

Purpose of the Study:

To highlight the utility of dermoscopy in diagnosing acral melanoma.
To discuss the interpretation of the parallel ridge pattern in acral lesions.

Main Methods:

Dermoscopic examination of acral skin lesions.
Analysis of the parallel ridge pattern's diagnostic significance.

Main Results:

Dermoscopy is a valuable tool for acral melanoma diagnosis.
The parallel ridge pattern has high specificity (99%) for melanoma but can appear in benign lesions.

Conclusions:

Accurate interpretation of dermoscopic patterns, including the parallel ridge, is essential.
Clinical history and lesion evolution are vital for differentiating acral melanoma from benign conditions.
