Summary
This study examines an acral fibrokeratoma, a benign skin tumor on the finger. Findings suggest it resulted from trauma causing connective tissue and epidermal overgrowth.
Area of Science:
- Dermatopathology
- Oncology
- Histology
Background:
- Acral fibrokeratomas are benign fibroepithelial tumors.
- Etiology often involves trauma.
- Differential diagnosis includes other skin neoplasms.
Observation:
- A 33-year-old male presented with a digital acral fibrokeratoma.
- Clinical examination revealed a finger lesion.
- Histopathological and immunohistological analyses were performed.
Findings:
- The tumor exhibited connective tissue hyperproliferation.
- Secondary epidermal hyperplasia was noted.
- Findings support a diagnosis of a traumatically induced fibroepithelial tumor.
Implications:
- Understanding the pathogenesis of acral fibrokeratomas is crucial for accurate diagnosis.
- Histopathology is key to differentiating benign from malignant lesions.
- This case highlights the role of trauma in tumor development.
