Summary
Conjunctival cavernous hemangioma, a benign vascular tumor, can mimic malignant conjunctival melanoma. Accurate diagnosis is crucial for appropriate treatment of these uncommon conjunctival lesions.
Area of Science:
- Ophthalmology
- Oncology
- Pathology
Background:
- Vascular conjunctival tumors are rare and typically benign.
- Conjunctival malignant melanoma (CMM) is a serious diagnosis requiring prompt management.
- Distinguishing benign from malignant conjunctival masses is critical for patient outcomes.
Observation:
- A 65-year-old male presented with a firm, dark-brown, non-mobile conjunctival mass.
- Initial clinical suspicion was conjunctival malignant melanoma (CMM).
- Ocular and systemic examinations were otherwise normal.
Findings:
- Histopathological examination revealed dilated vascular channels consistent with cavernous hemangioma.
- No evidence of malignancy was found, refuting the initial diagnosis of CMM.
- The lesion was characterized by vascular channels, red blood cells, and fibrous interstitium.
Implications:
- Conjunctival cavernous hemangioma can present with clinical features mimicking malignant conjunctival lesions.
- This benign vascular tumor may be misdiagnosed as CMM or other aggressive conditions.
- Accurate histopathological diagnosis is essential to avoid unnecessary aggressive treatment for benign conditions.
