    Content

    A 38-year-old male patient was seen in emergency room with sudden onset vertigo, headache and nausea. Acute neurologic problems were excluded on CT, but incidentally a cystic partially osteodestructive process (2.5 cm diameter) was detected in the lateral right frontal sinus (Panel A). The patient reported of recurrent frontal headache and occasional retrobulbar pressure. Because of the lateral localisation and for histologic workup we decided to perform osteoplastic frontal sinus surgery. Histological work- up presented histiocytes, siderophages, cholesterol crystals and spindle cell proliferation, without signs of malignity. Immunohistochemistry demonstrated SMA positivity with EMA, S100 and keratin negativity resulting in fibrous histiocytoma (Panel B - B-immunohistochemistry). Because of the potential of malignisation the tumorboard decided on close observation. Upon follow-up after three months the patient was free of complaints without progression on CT.

    In this location together with the CT findings this rare lesion has to be considered as differential diagnosis to a mucocele.
