The Histopathology of Chronic "Radiation Conjunctivitis" Shows Diagnostic Features Similar to Those Seen in Radiation Dermatitis, Including Radiation Fibroblasts.
Purpose: Radiation therapy is a treatment modality for various ocular and ocular adnexal tumors. The histopathology of chronic radiation dermatitis has been well-described. The authors present two cases demonstrating and characterizing "chronic radiation conjunctivitis" which has not been histopathologically illustrated in detail.
Methods: Retrospective case review of two patients who received proton beam irradiation for an anterior uveal melanoma and external beam radiation for conjunctival lymphoma, and developed leukoplakia and/or thickening of the eyelid margin and symblepharon. Hematoxylin and eosin-stained sections of eyelid margin and conjunctival biopsies as well as clinical histories were reviewed.
Results: Conjunctival biopsies in both cases revealed squamous epithelial metaplasia, chronic inflammation and bizarre-appearing stromal cells with hyperchromatic nuclei in a fibrotic/sclerotic stroma, consistent with chronic radiation conjunctivitis. These stromal cells are believed to be the same "radiation fibroblasts" described in chronic radiation dermatitis.
Conclusion: The radiation fibroblast is characteristic for the diagnosis of chronic radiation conjunctivitis, as it is in radiation dermatitis. Features of squamous metaplasia of conjunctival epithelium, keratinization, subepithelial fibrosis/sclerosis and chronic inflammation are frequently found but not specific. A detailed history and other ancillary tests help differentiate cicatrizing conjunctival conditions, and biopsy should be performed in the setting of suspicion for a secondary malignancy.
期刊介绍：
Head & Neck Pathology presents scholarly papers, reviews and symposia that cover the spectrum of human surgical pathology within the anatomic zones of the oral cavity, sinonasal tract, larynx, hypopharynx, salivary gland, ear and temporal bone, and neck.
The journal publishes rapid developments in new diagnostic criteria, intraoperative consultation, immunohistochemical studies, molecular techniques, genetic analyses, diagnostic aids, experimental pathology, cytology, radiographic imaging, and application of uniform terminology to allow practitioners to continue to maintain and expand their knowledge in the subspecialty of head and neck pathology. Coverage of practical application to daily clinical practice is supported with proceedings and symposia from international societies and academies devoted to this field.
Single-blind peer review
The journal follows a single-blind review procedure, where the reviewers are aware of the names and affiliations of the authors, but the reviewer reports provided to authors are anonymous. Single-blind peer review is the traditional model of peer review that many reviewers are comfortable with, and it facilitates a dispassionate critique of a manuscript.
