Summary
This study analyzed 100 limbal neoplasms, finding benign tumors like dermoids are most common, especially in younger patients. Squamous cell carcinoma was the most frequent malignancy observed.
Area of Science:
- Ophthalmology
- Oncology
- Pathology
Background:
- Limbal neoplasms are growths on the surface of the eye at the junction of the cornea and sclera.
- Understanding the prevalence and types of limbal neoplasms is crucial for diagnosis and treatment.
- Previous studies have varied in their findings regarding the demographics and common types of these tumors.
Purpose of the Study:
- To analyze the histopathological features of consecutively excised limbal neoplasms.
- To determine the relative frequencies of benign and malignant limbal tumors.
- To compare findings with existing Indian and Western literature and discuss implications.
Main Methods:
- Retrospective analysis of 100 consecutive limbal neoplasms.
- Histopathological diagnosis of all excised specimens.
- Demographic data collection and statistical analysis of tumor types.
Main Results:
- The majority of patients (56%) were under 30 years old.
- Benign neoplasms (77%) were more common than malignancies.
- Dermoids (29%) and epidermalization (26%) were the most frequent benign types, while squamous cell carcinoma (23%) was the most common malignancy.
Conclusions:
- Limbal neoplasms, particularly benign types like dermoids, are prevalent in younger individuals.
- Squamous cell carcinoma remains a significant malignant limbal neoplasm.
- Further comparative studies are needed to understand regional variations in limbal neoplasm characteristics.
