Synthetic Fiber Granuloma Misdiagnosed as Chalazion in an 8-year-old Child

ABSTRACT

Purpose@#We report a case of conjunctival synthetic fiber granuloma, which was misdiagnosed as chalazion. Case summary: An 8-year-old female patient, without any previous medical illness or ocular trauma history, visited our hospital with a prolonged mass-like lesion in the left lower palpebral conjunctiva. In her detailed medical history, she said that she often played with her doll's hair. The conjunctival mass first occurred 1 week before her visit to the private clinic. At that time, eye drop treatment was initiated under the diagnosis of chalazion. The child showed no improvement; thus, incision and curettage were performed. The mass in the conjunctiva continued to persist, so she was transferred to the hospital for a biopsy. Slit-lamp examination revealed a patterned agglomeration of fiber strands inside the mass. Complete excisional biopsy was performed under general anesthesia. Histopathological examination revealed a fibrous foreign body in the birefringence, with granulomatous inflammation surrounding it. The patient was diagnosed with synthetic fiber granuloma. @*Conclusions@#Conjunctival synthetic fiber granulomas are easily mistaken as chalazion. If specific fibrous strands are entangled inside the mass on slit-lamp examination, diagnosis and treatment through therapeutic excisional biopsy are required under clinical suspicion.
