Summary
Dermatofibrosarcoma protuberans (DFSP) can be challenging to diagnose due to its rarity. Dermoscopy reveals key features like vessels and pigmented networks, aiding early clinical suspicion for this rare tumor.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Dermatofibrosarcoma protuberans (DFSP) is a rare, intermediate-grade mesenchymal tumor.
- Delayed diagnosis of DFSP is common due to its slow progression and rarity.
- Limited published data exists on the dermoscopic features of DFSP.
Purpose of the Study:
- To describe the dermoscopic features of two DFSP cases.
- To review and synthesize existing literature on dermoscopy for DFSP diagnosis.
- To enhance understanding of dermoscopic patterns in DFSP.
Main Methods:
- Literature search for published dermoscopic cases of DFSP.
- Presentation and analysis of two additional DFSP cases.
- Comparative analysis of findings from 32 patients.
Main Results:
- Vessels were the most frequent dermoscopic finding (81%).
- A pigmented network was observed in 78% of cases.
- A pinkish background was present in 66% of DFSP cases.
Conclusions:
- DFSP can clinically resemble benign skin lesions, complicating diagnosis.
- Dermoscopy is a valuable tool for increasing clinical suspicion of DFSP.
- Identifying characteristic dermoscopic features can aid in earlier diagnosis.

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...

01:30Skin 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.
