Summary
Basal cell carcinoma (BCC), a common skin cancer, rarely affects the toes. This case study details a superficial BCC found on a patient's right hallux, highlighting an unusual presentation of this skin neoplasm.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Basal cell carcinoma (BCC) is the most common type of skin cancer.
- BCCs typically arise on sun-exposed skin.
- The digits, including toes, are exceptionally rare locations for BCC development.
Observation:
- A patient presented with a clinical diagnosis of a skin lesion on the right hallux.
- The lesion appeared as a small, brown plaque with irregular borders.
- It was located on the nail fold and dorsal aspect of the hallux.
Findings:
- Histopathological examination confirmed the diagnosis of basal cell carcinoma.
- The specific subtype identified was superficial BCC.
- This confirms an extremely rare occurrence of BCC on the hallux.
Implications:
- This case expands the known clinical spectrum and anatomical distribution of basal cell carcinoma.
- It underscores the importance of considering rare diagnoses in dermatological presentations.
- Further research may be warranted to understand BCC development in unusual sites like the nail unit and digits.
