Summary
Multiple clear cell acanthoma (CCA) lesions were identified in a 69-year-old male. Videodermatoscopy aided in diagnosing these skin papules by revealing characteristic vascular patterns, distinguishing CCA from similar conditions.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Clear cell acanthoma (CCA) is a benign skin neoplasm.
- Multiple presentations of CCA are rare.
- Accurate diagnosis is crucial to differentiate from other skin conditions.
Observation:
- A 69-year-old male presented with multiple, reddish, smooth papules on the legs.
- Videodermatoscopy revealed symmetrical, net-like, pinpoint vascular structures with a bush-like appearance at higher magnification.
- Histopathology confirmed the diagnosis of clear cell acanthoma.
Findings:
- The observed dermatoscopic vascular pattern, though not entirely specific, is characteristic of clear cell acanthoma.
- Videodermatoscopy demonstrated a consistent pattern across all multiple lesions.
- Histological examination confirmed the clinical and dermatoscopic suspicion of CCA.
Implications:
- Videodermatoscopy can enhance the clinical diagnosis of both single and multiple clear cell acanthomas.
- This technique aids in differentiating CCA from clinically similar skin disorders based on distinct vascular patterns.
- Improved diagnostic accuracy through videodermatoscopy can guide appropriate patient management.
