AB Cholesteatoma of the paranasal sinus is a very rare condition. As in the tympanomastoid region where cholesteatomas are a common entity, the paranasal sinus cholesteatomas also tend to erode the surrounding bony structures. Because of the extensive bony erosion, this condition often masquerades as a chronic granulomatous or a malignant lesion. Clinical presentation can be quite varied like facial deformities, visual and neurological deficits. Radiological findings are also non-specific making a preoperative diagnosis challenging. Histopathological examination is the only confirmatory investigation. We present a patient with frontal cholesteatoma who presented with forehead swelling of 1 month duration. Since the diagnosis could be obtained only intraoperatively, the patient required multiple surgeries. Frontal sinus cholesteatomas often require a combined endoscopic and external approach to ensure complete disease clearance. Periodic follow-up is essential to rule out recurrence.
