Summary
A rare, pale basal cell carcinoma (BCC) presented as a macule on a patient with sun-damaged skin. This case highlights the need for vigilance in diagnosing unusual BCC presentations.
Area of Science:
- Dermatology
- Oncology
Background:
- Basal cell carcinoma (BCC) is the most common skin cancer.
- Micronodular BCC often presents as an erythematous macule or papule/plaque.
- Accurate diagnosis is crucial for effective patient management.
Observation:
- A 63-year-old woman with light skin and chronic sun damage presented with a painless, pale macule on her nasal tip.
- Differential diagnoses included vitiligo and morpheaform basal cell carcinoma (BCC).
Findings:
- Punch biopsy confirmed a micronodular basal cell carcinoma (BCC).
- This presentation was unusual, differing from typical micronodular BCC manifestations.
Implications:
- Clinicians must consider diverse differential diagnoses for skin lesions.
- Vigilance is essential for identifying rare presentations of basal cell carcinoma.
- Early and accurate diagnosis of BCC improves patient outcomes.
