Abstract
PURPOSE: Intratarsal keratinous cysts (IKCs) have been frequently misdiagnosed as chalazia or epidermal cysts. We reviewed a series of cases of IKCs to identify clinical features that distinguish IKCs from other eyelid diseases. METHODS: We retrospectively reviewed the medical records of 17 suspected IKC patients between January 2004 and September 2014. RESULTS: Seventeen patients who were clinically suspected to have IKC were enrolled. All patients presented with non-inflamed eyelid nodules fixed to the tarsus. Among them, 12 biopsy specimens were available and 11 patients (91.7%) were diagnosed with IKC, with a pathological finding of stratified squamous cell lining with keratin material. The mean patient age was 55.1 years (31-71). Six patients had a surgical history of incision or incomplete excision of the lesion, followed by recurrence. On eyelid eversion, five patients showed a white-yellow nodule, and three patients had a bluish cystic lesion. The diameter of the nodules ranged from 4 to 10 mm. The intracystic material was a milky white fluid. Ten patients underwent a complete surgical excision including partial tarsectomy and there was no recurrence. CONCLUSIONS: IKC can be distinguished from other intratarsal lesions by a characteristic tarsal nodule fixed to the tarsus. To prevent recurrence, complete excision with partial tarsectomy is needed.
