Summary
Subungual osteochondromas, rare benign bone tumors under the nail, can cause nail deformities and be misdiagnosed. This report details two cases of toe osteochondromas with skin penetration, exploring their features and treatment.
Area of Science:
- Orthopedic Surgery
- Oncology
- Dermatology
Background:
- Osteochondroma is the most common benign bone tumor.
- Subungual osteochondroma, particularly on the distal phalanx of the great toe, is rare.
- Lesions in this location can present with cutaneous penetration and nail deformity, leading to misdiagnosis.
Observation:
- Two cases of subungual osteochondroma of the distal phalanges of the first toes are presented.
- Both cases involved cutaneous penetration of the osteochondroma.
- Clinical, histologic, and radiographic features were analyzed.
Findings:
- Subungual osteochondromas can mimic other conditions due to their location and potential for skin penetration.
- Histological examination confirms the benign nature of osteochondroma.
- Radiographic imaging aids in diagnosis and surgical planning.
Implications:
- Early recognition and accurate diagnosis of subungual osteochondroma are crucial to prevent misdiagnosis and ensure appropriate treatment.
- Surgical excision is the primary treatment modality.
- Understanding the clinical presentation and diagnostic features can improve patient outcomes for this rare bone tumor.
