Neoplastic change in chronic leg ulcer

J O Oluwasanmi, F A Ofodile, A A Abioye

    International Surgery
    |October 1, 1982

    Summary

    Chronic leg ulcers can develop into squamous cell carcinoma, particularly those with recurrent healing and breakdown. Pseudoepitheliomatous hyperplasia may indicate early malignancy, necessitating deeper tissue examination for accurate diagnosis.

    Area of Science:

    • Dermatology
    • Oncology
    • Pathology

    Background:

    • Chronic leg ulcers represent a significant clinical challenge.
    • Malignant transformation in chronic wounds is a known but infrequent complication.
    • Understanding the precursors to malignancy in these lesions is crucial for early detection.

    Purpose of the Study:

    • To investigate the histological characteristics of malignancies arising in chronic leg ulcers.
    • To identify potential precursor lesions and risk factors for malignant transformation.
    • To evaluate the association between ulcer chronicity and neoplastic development.

    Main Methods:

    • Retrospective analysis of 17 cases of chronic leg ulcers with malignant transformation.
    • Histopathological examination of ulcer tissues, including assessment of differentiation and associated hyperplastic changes.
    • Review of clinical data including ulcer duration, healing patterns, and treatment modalities.

    Main Results:

    • Squamous cell carcinoma was the predominant malignancy (16/17 cases), with one sarcoma.
    • Malignancies frequently arose from ulcers with recurrent healing and breakdown (11/17 cases).
    • Pseudoepitheliomatous hyperplasia was a significant finding, potentially representing an early stage of neoplastic change (fetoplasia).

    Conclusions:

    • Chronic leg ulcers, especially those with fluctuating healing, carry a risk of developing squamous cell carcinoma.
    • Pseudoepitheliomatous hyperplasia in chronic ulcers warrants thorough investigation for underlying malignancy.
    • Further research into fetal markers may aid in understanding and diagnosing early neoplastic changes in these lesions.
