[CD8-positive, CD30-negative cutaneous T-cell lymphoma simulating pyoderma gangrenosum]
1Krankenhaus Neukölln, Abteilung für Dermatologie und Venerologie, Rudower Strasse 48, 12351 Berlin.
Summary
A rare CD8-positive cutaneous lymphoma mimicked pyoderma gangrenosum in a patient. Radiotherapy led to complete remission, with no relapse after 28 months, highlighting an extraordinary clinical presentation and successful treatment.
Area of Science:
- Dermatology
- Oncology
- Immunohistochemistry
Background:
- Primary cutaneous lymphomas (PCLs) are a heterogeneous group of non-Hodgkin lymphomas.
- Ulcerated PCLs are known, but presentation mimicking pyoderma gangrenosum is exceptionally rare.
- CD8-positive lymphomas represent a rare subtype with variable clinical outcomes.
Observation:
- A 49-year-old patient presented with a large, ulcerated lesion on the chest wall.
- The lesion clinically resembled pyoderma gangrenosum.
- Immunohistochemical staining revealed a CD8-positive lymphocyte infiltrate, with absent CD30 expression.
Findings:
- The patient was diagnosed with an unclassifiable, ulcerated, CD8-positive primary cutaneous lymphoma.
- Treatment with radiotherapy, specifically complete skin irradiation, resulted in complete regression of the lymphoma.
- The patient remained disease-free for 28 months post-treatment.
Implications:
- This case highlights an unusual clinical presentation of CD8-positive PCL.
- It underscores the importance of thorough histopathological examination for diagnosing cutaneous lymphomas.
- Successful management with radiotherapy suggests its efficacy in selected cases of CD8-positive PCL.
