Summary
Painless orbital tumors in three men were surgically removed. Histology confirmed chronic hematic cysts, suggesting a new differential diagnosis for orbital bone lysis.
Area of Science:
- Ophthalmology
- Neurosurgery
- Pathology
Background:
- Orbital tumors can present with varied symptoms and radiographic findings.
- Differentiating benign from malignant orbital lesions is crucial for appropriate management.
Observation:
- Three middle-aged male patients presented with painless superior temporal orbital tumors causing proptosis.
- Radiographic imaging showed bone lysis extending from the frontal bone to the periorbita and dura.
Findings:
- Surgical excision and curettage successfully removed the orbital lesions.
- Histopathological examination revealed cystic lesions with granulomatous inflammation and blood breakdown products, consistent with chronic hematic cysts.
- Cholesterol clefts, hemosiderin, giant cells, and hematoidin were noted within the cysts, surrounded by a fibrous pseudocapsule.
Implications:
- Chronic hematic cysts should be considered in the differential diagnosis of orbital tumors with bone erosion.
- Complete surgical removal is an effective treatment for these lesions.
- Understanding the histopathological features aids in accurate diagnosis and management of orbital masses.
