    Summary
    This summary is machine-generated.

    Subungual exostoses are benign bone tumors, most commonly affecting the great toe. Local excision is the recommended treatment, with a low rate of recurrence and no malignant transformation observed.

    Area of Science:

    • Orthopedic Surgery
    • Skeletal Tumors
    • Podiatric Medicine

    Background:

    • Subungual exostoses are benign cartilaginous tumors.
    • They commonly occur under the nail, particularly on the great toe.
    • These growths can cause pain and nail deformity.

    Purpose of the Study:

    • To review the clinical presentation, treatment, and outcomes of subungual exostoses.
    • To evaluate the recurrence rates and potential for malignant transformation.
    • To establish the optimal surgical approach for subungual exostoses.

    Main Methods:

    • Retrospective review of 44 patients diagnosed with subungual exostoses between 1910 and 1975.
    • Analysis of treatment modalities, including local excision and amputation.

    Related Experiment Videos

  • Histopathological examination of tumor specimens.

    • Main Results:

    • Thirty-four of 44 patients had great toe involvement.
    • Local excision was performed in 43 patients; one underwent hallux amputation.
    • Five patients experienced local recurrence; no malignancies were identified.

    Conclusions:

    • Subungual exostoses are uniformly benign tumors.
    • Local excision is the preferred treatment method.
    • The risk of malignant change is negligible, and recurrence rates are low.
