Summary
Cutaneous T-cell lymphoma (CTCL) can affect the nail apparatus, causing severe nail dystrophy. This case highlights CTCL as a cause of widespread nail changes in elderly patients.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Cutaneous T-cell lymphoma (CTCL) is a diverse group of malignant T-cell proliferations primarily affecting the skin.
- Nail involvement in CTCL is uncommon but can manifest in various forms.
- Early diagnosis and appropriate management are crucial for patient outcomes.
Observation:
- A case report details an elderly woman diagnosed with cutaneous T-cell lymphoma.
- The patient presented with dystrophic changes affecting all 20 fingernails and toenails.
- Histopathological examination revealed lymphomatous infiltration of the nail apparatus.
Findings:
- The primary cause of the extensive nail dystrophy was identified as a lymphomatous infiltrate within the nail unit.
- This finding underscores the potential for CTCL to manifest with significant onychodystrophy.
- The case illustrates a rare presentation of CTCL involving the entire nail apparatus.
Implications:
- This case expands the differential diagnosis for severe, unexplained onychodystrophy, particularly in elderly individuals.
- It emphasizes the importance of considering systemic diseases, including cutaneous T-cell lymphoma, in patients with widespread nail abnormalities.
- Further research into nail apparatus involvement in CTCL may improve diagnostic strategies and treatment approaches.
