Area of Science:

  • Dermatology
  • Pathology
  • Oncology

Background:

  • Lymphomatoid papulosis (LyP) is a rare, primary cutaneous T-cell lymphoproliferative disorder.
  • It is characterized by recurrent, self-healing papules and nodules, often with epidermal changes.
  • LyP presents a diagnostic challenge due to its variable clinical and histological features.

Observation:

  • A 36-year-old man presented with a long-standing history of solitary, necrotic skin nodules on his extremities since 1988.
  • The lesions exhibited spontaneous regression, leaving scars.
  • Histopathology revealed a superficial and deep perivascular and interstitial infiltrate with atypical lymphocytes, including cerebriform mononuclear cells and large atypical cells positive for MT1, UCHL1, and Ber-H2 (CD30).

Findings:

  • The patient was diagnosed with lymphomatoid papulosis.
  • No associated systemic disease was identified.
  • The patient achieved complete remission for over a year without any intervention.

Implications:

  • This case underscores the importance of thorough histopathological examination for diagnosing lymphomatoid papulosis.
  • The spontaneous resolution observed in this patient offers insights into the potential natural course of the disease.
  • Further research into the physiopathology of LyP may elucidate mechanisms for spontaneous remission and inform treatment strategies.
