Dermoscopic Findings in Trichoblastoma

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.
