Summary
Squamous cell carcinoma of the nail bed is a rare cancer that can be misdiagnosed due to its subtle presentation. Early detection requires nail plate removal and biopsy for accurate diagnosis.
Area of Science:
- Dermatology
- Oncology
Background:
- Squamous cell carcinoma (SCC) of the nail bed is an uncommon malignancy.
- Delayed diagnosis is frequent due to subtle or prolonged symptoms.
Observation:
- Two cases of subungual SCC are presented in elderly men.
- Symptoms included discomfort, discoloration, and discharge lasting years.
- Initial clinical examination showed only minor nail abnormalities.
Findings:
- SCC was confirmed only after nail plate removal and nail bed biopsy.
- The tumor presented with prolonged symptoms and a deceptively benign appearance.
Implications:
- Highlights the importance of considering malignancy in persistent nail bed conditions.
- Emphasizes the diagnostic value of nail plate removal for direct inspection and biopsy.
- Underscores the need for vigilance in diagnosing subungual squamous cell carcinoma.
