Radiotherapy of polymorphic reticulosis

E C Halperin, D E Dosoretz, M Goodman

    The British Journal of Radiology
    |September 1, 1982
    PubMed
    Summary

    Lethal midline granuloma is a misnomer for non-infectious mid-facial destruction. Polymorphic reticulosis (PR), a rare disease, is histologically identical to lymphomatoid granulomatosis (LG) and treatable with radiation therapy.

    Area of Science:

    • Pathology
    • Oncology
    • Otolaryngology

    Background:

    • The term "lethal mid-line granuloma" is outdated and inaccurate for describing non-infectious mid-facial destructive diseases.
    • Accurate classification relies on clinical and histological criteria, distinguishing Wegener's from non-Wegener's causes.

    Observation:

    • Non-Wegener's causes include extranodal lymphoma, idiopathic mid-line granuloma, and polymorphic reticulosis (PR).
    • Polymorphic reticulosis (PR) is histologically identical to lymphomatoid granulomatosis (LG), often termed PR-LG when localized to the upper airways.
    • PR-LG presents as a polymorphic angiocentric cellular infiltrate, locally invasive with potential for systemic spread, causing constitutional symptoms like fever and weight loss.

    Findings:

    • PR-LG localized to the upper airways is potentially controllable with radiation therapy.
    • Radiation therapy can also palliate local symptoms at other body sites.
    • The study reviews two patient cases and their radiotherapy, alongside relevant literature.

    Implications:

    • Reclassifying mid-facial destructive diseases improves diagnostic accuracy and treatment strategies.
    • Radiation therapy offers a viable treatment option for localized PR-LG, improving patient outcomes.
    • Further research into the specific mechanisms and optimal management of PR-LG is warranted.
