Summary
Onychomatricoma is a rare nail matrix tumor. This study details its clinical and histopathological features, aiding diagnosis and treatment through complete tumor excision.
Area of Science:
- Dermatopathology
- Oncology
Background:
- Onychomatricoma is an exceptionally rare benign neoplasm originating from the nail matrix.
- To date, only eight cases have been documented in medical literature.
Observation:
- A case study of a 62-year-old male patient presenting with onychomatricoma.
- Clinical presentation includes longitudinal yellowish nail discoloration with splinter hemorrhages, nail plate thickening, and increased curvature.
Findings:
- Histopathological analysis reveals a matrix tumor composed of fine filiform projections extending into the thickened nail plate.
- The observed clinical and histopathological characteristics are distinctive for onychomatricoma.
Implications:
- Accurate diagnosis of onychomatricoma is achievable based on its unique clinical and histopathological profile.
- Complete surgical excision is the recommended treatment for onychomatricoma.
