Summary
Conjunctival T-cell lymphoma is a rare diagnosis for gelatinous lesions. This case report highlights the diagnostic process and emphasizes the unknown optimal treatment for this rare ocular lymphoma.
Area of Science:
- Ophthalmology
- Oncology
- Pathology
Background:
- Conjunctival T-cell lymphoma is an exceptionally rare condition.
- Early and accurate diagnosis is crucial for appropriate management.
Observation:
- A case of conjunctival T-cell lymphoma presenting as a gelatinous lesion is reported.
- Clinical examination, excisional biopsy, and immunostaining were utilized for diagnosis.
Findings:
- Histopathology revealed chronic inflammatory cell infiltrate with lymphocyte exocytosis.
- Immunostaining confirmed T-cell markers (CD-45 RO positive) and ruled out B-cell markers (CD-20 negative).
- T-cell receptor gene rearrangement confirmed clonality, establishing the diagnosis of T-cell lymphoma.
Implications:
- Conjunctival T-cell lymphoma should be considered in the differential diagnosis of unusual conjunctival lesions.
- The optimal treatment strategy for conjunctival T-cell lymphoma remains undetermined due to its rarity and lack of systemic involvement in this case.
