Periocular petrolatum.
OBJECTIVE
This report describes the clinical and histopathologic features and discusses the diagnostic difficulties and management of periocular deposition of petrolatum-based materials.


METHODS
Excision of orbital and eyelid tissue, tissue processing, and histopathologic examination was performed in patients with deposition of petroleum-based products. Transmission electron microscopy was performed in 3 cases.


RESULTS
Between 1983 and 2003, 11 patients were diagnosed with periocular petrolatum deposition, based on clinical history and the characteristic histopathologic features of polymorphic dropout spaces, and varied from a noninflammatory lesion (paraffinoma) to those with an associated granulomatous inflammatory reaction.


CONCLUSIONS
The diagnosis of petrolatum deposition can be challenging due to the range of symptoms and variable delay in presentation. Petrolatum products should be avoided during surgery and used judiciously in the postoperative period. To avoid confusion with nonspecific cases of lipogranulomatous inflammation, the terms "ointment granuloma" or "orbital paraffinoma" should be used to refer to patients presenting with orbital/eyelid lesions caused by ointment use.
