Skin Cancer

6.6K
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...

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...

Summary

Trichoblastoma, a benign skin tumor, shares similarities with basal cell carcinoma. Dermoscopy reveals delicate telangiectases, aiding in differentiating trichoblastoma from basal cell carcinoma.

Area of Science:

  • Dermatology
  • Dermoscopy
  • Oncology

Background:

  • Trichoblastoma is a benign cutaneous neoplasm.
  • It is clinically and histologically similar to basal cell carcinoma.
  • Accurate diagnosis is crucial for appropriate patient management.

Observation:

  • This report details the dermoscopic features of two facial trichoblastoma cases.
  • Case 1 showed fine, scarcely branching telangiectases on a pearly white background.
  • Case 2 exhibited short, scarcely branching veins in a crown pattern, with white striae and milia-like cysts.

Findings:

  • Fine, scarcely branching telangiectases were observed in both trichoblastoma cases.
  • Specific vascular patterns and associated features like milia-like cysts were noted.
  • These dermoscopic findings may help distinguish trichoblastoma from nodular basal cell carcinoma.

Implications:

  • Dermoscopy offers valuable insights into the diagnosis of trichoblastoma.
  • Recognizing these specific dermoscopic features can improve differential diagnosis.
  • This can lead to more accurate and timely treatment of benign skin neoplasms.
