[Differential diagnoses of dry eye syndrome and blepharitis]

[Hordeolum and chalazion : (Differential) diagnosis and treatment]

Hordeolum and chalazion are the most frequent inflammatory eyelid tumors. They can occur in association with underlying diseases causing Meibomian gland dysfunction and/or chronic blepharitis. Due to the typical morphological features and clinical course, the diagnosis can mostly be clinically established. The majority of these lesions resolve spontaneously over time. In some instances, surgical intervention is unavoidable. In persistent, recurrent or clinically atypical cases malignant tumors must be excluded as a differential diagnosis by excisional biopsy and histopathological assessment.
