Telangiectasia macularis eruptiva perstans

Last edited: 4/16/2026

Overview

Telangiectasia macularis eruptiva perstans (TMEp) is a rare, chronic skin condition characterized by persistent telangiectatic lesions, predominantly affecting the face and upper trunk, often with minimal systemic involvement 1.

Diagnosis

  • Clinical presentation of persistent, asymptomatic, reddish-brown telangiectatic macules 1.
  • No specific laboratory tests; diagnosis is primarily clinical 1.
  • Differential diagnosis includes erythema dyschromicum perstans and other persistent pigmentary disorders 1.

    • Management

  • No definitive cure; management focuses on symptomatic relief and patient reassurance 1.
  • Topical corticosteroids may be used for symptomatic improvement, though efficacy is not well-documented 1.
  • Sun protection is recommended to prevent exacerbation of telangiectatic lesions 1.

    • Special Populations

  • Limited data available on specific management in pregnancy, pediatrics, elderly, or comorbid conditions 1.
  • Recommendations vary 1.

    • Key Recommendations

  • Confirm diagnosis based on characteristic clinical features without relying on specific laboratory tests (Evidence: Expert opinion 1).
  • Provide symptomatic support and patient education, emphasizing sun protection (Evidence: Expert opinion 1).
  • Consider low-potency topical corticosteroids for symptomatic relief, acknowledging limited evidence (Evidence: Weak 1).
