Summary
This study details a Japanese case of primary cutaneous marginal zone B-cell lymphoma (PCMZL). Reviewing 16 Japanese PCMZL cases reveals common clinical and histopathological features, with no specific chromosomal aberrations found.
Area of Science:
- Dermatology
- Hematology
- Oncology
Background:
- Primary cutaneous marginal zone B-cell lymphoma (PCMZL) is a rare non-Hodgkin lymphoma.
- Understanding its characteristics in different populations is crucial for diagnosis and management.
Purpose of the Study:
- To report a case of PCMZL in a Japanese patient.
- To review and analyze previously reported Japanese cases of PCMZL.
Main Methods:
- Case report of a 46-year-old woman with a forearm nodule.
- Literature review of 16 Japanese PCMZL cases.
- Analysis of morphology, immunophenotype, molecular data, clinical presentation, and histopathology.
Main Results:
- The reported case was diagnosed as PCMZL based on comprehensive analysis.
- Japanese PCMZL cases showed a slight female predilection, with lesions typically on the face, neck, trunk, and arms.
- Lymphoepithelial lesions were common; specific chromosomal aberrations typical of MALT lymphoma were not observed.
Conclusions:
- PCMZL presents with characteristic clinical and histopathological features in Japanese patients.
- The absence of specific chromosomal aberrations warrants further investigation.
- While metastasis can occur, PCMZL appears to have a favorable prognosis in this cohort.
