Benign fibrous histiocytoma

Area of Science:

• Ophthalmology
• Oncology
• Dermatopathology

Background:

• Fibrous histiocytomas (FHs) are mesenchymal neoplasms with variable malignant potential.
• Ocular involvement by FHs is uncommon, typically restricted to the orbit.
• Rarely, FHs can manifest in the conjunctiva and perilimbal regions.

Observation:

• A case study of a 38-year-old male patient presenting with distinct FHs.
• The patient exhibited FHs affecting the eyelid, conjunctiva, and neck.
• Clinical presentation suggested neoplastic lesions in these anatomical locations.

Findings:

• Histopathological examination confirmed the diagnosis of fibrous histiocytoma.
• The findings support the rare occurrence of FHs in the conjunctiva and associated structures.
• Multifocal FHs involving the ocular adnexa and neck were identified.

Implications:

• This case expands the understanding of the clinical spectrum and anatomical distribution of fibrous histiocytomas.
• Highlights the importance of histopathological confirmation for diagnosing rare ocular adnexal tumors.
• Suggests the need for vigilance in evaluating eyelid and conjunctival lesions for mesenchymal neoplasms.
