Chalazion coexisting with dacryolithiasis
1Department of Dermatology, Kyushu University, Beppu, Japan.
Insights
A painless eyelid nodule, initially suspected as pilomatricoma, was histologically diagnosed as chalazion. Coexisting dacryolithiasis may play a role in chalazion development.
Area of Science:
- Ophthalmology
- Dermatopathology
Background:
- Eyelid nodules can present diagnostic challenges, with pilomatricoma and chalazion being common considerations.
- Accurate histopathological examination is crucial for differentiating benign eyelid lesions.
Observation:
- A 41-year-old woman presented with a hard, painless subcutaneous nodule on her right upper eyelid.
- Clinical diagnosis suggested pilomatricoma, leading to surgical excision.
- Histopathology revealed a granulomatous lesion with foamy mononuclear cells, multinucleated giant cells, and granulocytes, alongside lipid droplets and dilated ductal structures.
Findings:
- The granulomatous lesion was identified as chalazion.
- An associated intraductal dacryolith was observed near the chalazion.
- The presence of dacryolithiasis was implicated as a potential factor in the chalazion's pathogenesis.
Implications:
- This case highlights the importance of histopathology in diagnosing eyelid lesions, distinguishing chalazion from other tumors like pilomatricoma.
- The findings suggest a potential link between dacryolithiasis and chalazion formation, offering insights into its etiology.
- Understanding this association may guide future clinical management and research into chalazion pathogenesis.
Abstract:
A 41-year-old woman presented with a painless hard subcutaneous nodule in the right upper eyelid. The lesion was diagnosed clinically as pilomatricoma and removed surgically. Histological examination disclosed a granulomatous lesion composed mainly of mononuclear cells with a foamy appearance and multinucleated giant cells with some admixture of granulocytes, plasma cells, and lymphoid cells. Lipid droplets and dilated ductal structures containing an eosinophilic fibrillar substance were observed in and around the granulomatous lesion. In addition, an intraductal dacryolith was seen near the granulomatous lesion. We finally diagnosed this case as chalazion; the coexisting dacryolithiasis was considered to be involved in the pathogenesis of chalazion.
