Solitary spindle-cell xanthogranuloma of the eyelid

To describe a rare presentation of a solitary spindle-cell xanthogranuloma in a 3-year-old boy with a 6-month history of a right upper lid soft tissue lesion.

Interventional case report.

An excisional full-thickness biopsy of the right upper lid was performed. Histologic examination and immunohistochemistry of the specimen were performed.

Histopathologic evaluation revealed a well-demarcated nodule arising from the tarsus that contained a storiform array of spindle cells admixed with numerous multinucleated giant cells (some Touton type) and lymphocytes. The spindle cells labeled with antibodies to Factor XIIIa, CD68, lysozyme, Mac 387, and vimentin. The multinucleate giant cells labeled with CD68, lysozyme, and vimentin. Findings were consistent with the diagnosis of solitary spindle-cell xanthogranuloma.

Spindle-cell xanthogranuloma resembles juvenile xanthogranuloma and fibrous histiocytoma (dermatofibroma) and should be considered in the differential diagnosis of spindle-cell tumors of the eyelid and periocular region. If similar lesions are noted elsewhere, the diagnosis of progressive nodular histiocytoma should be considered.
