Summary

A rare iris varix, a vascular malformation, presented as a pigmented nodule causing hyphema. Histology confirmed the diagnosis, though distinguishing it from iris hemangioma or melanoma can be challenging.

Area of Science:

  • Ophthalmology
  • Pathology

Background:

  • Iris tumors require careful differential diagnosis.
  • Vascular lesions of the iris can present with varied clinical features.

Observation:

  • A 56-year-old man presented with a rapidly enlarging pigmented iris nodule with prominent vessels.
  • The lesion caused recurrent hyphema (bleeding into the anterior chamber).
  • Clinical differential diagnoses included iris hemangioma and malignant melanoma.

Findings:

  • Histological examination revealed a stromal cavity filled with fibrin and erythrocytes.
  • The diagnosis of an iris varix was established.
  • Distinguishing iris varix from iris hemangioma and melanoma can be histologically challenging.

Implications:

  • This case highlights the importance of considering iris varix in the differential diagnosis of iris tumors.
  • Histopathological features can overlap between iris varix, hemangioma, and melanoma.
  • Accurate diagnosis is crucial for appropriate management of iris vascular lesions.
