Primary Periorbital Extra-skeletal Osteoma: A Novel Clinical Entity

Area of Science:

• Ophthalmology
• Oncology
• Pathology

Background:

• Osteomas are benign, slow-growing bone tumors.
• Orbital osteomas are exceptionally rare, with limited documented cases.
• Typically, orbital osteomas exhibit a bony connection to the orbit.

Purpose of the Study:

• To report the first documented case of a primary periorbital extra-skeletal osteoma.
• To contribute to the literature on rare orbital and periorbital tumors.
• To highlight the characteristics of non-osseous osteomas in the periorbital region.

Main Methods:

• Case report presentation.
• Review of relevant medical literature.
• Clinical and radiological assessment of the periorbital mass.

Main Results:

• The authors describe a unique case of a primary periorbital osteoma lacking an osseous connection.
• This finding expands the known spectrum of osteoma presentation.
• The tumor was benign and slow-growing, consistent with typical osteoma behavior.

Conclusions:

• Primary periorbital extra-skeletal osteomas are exceedingly rare.
• This case broadens the understanding of osteoma locations and presentations.
• Further research may elucidate the etiology and management of such rare extra-skeletal bone tumors.
