Summary
Localized cutaneous anaplastic large-cell lymphoma (ALCL) in a 63-year-old woman presented as a subumbilical nodule. This high-grade lymphoma showed a favorable prognosis, with surgery or radiotherapy being effective treatments.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Anaplastic large-cell lymphoma (ALCL) is a type of non-Hodgkin lymphoma.
- Cutaneous localization of ALCL can present unique diagnostic and prognostic challenges.
Observation:
- A 63-year-old female patient presented with a significant, ulcerated nodule in the subumbilical region.
- The nodule was histopathologically identified as Ki-1-positive anaplastic large-cell lymphoma.
Findings:
- The lymphoma exhibited exclusive localization to the skin (cutaneous anaplastic large-cell lymphoma).
- Despite being high-grade, this specific case demonstrated a less severe clinical course and prognosis.
- Surgical excision and local radiotherapy were identified as potentially curative or sufficient treatment modalities.
Implications:
- Localized cutaneous ALCL may have a more favorable prognosis than systemic forms.
- This case supports the efficacy of localized treatment approaches for skin-limited ALCL.
- Further research into the specific characteristics and management of cutaneous ALCL is warranted.
