Giant cell fibroma is a fibrous tumor which represents about 2 to 5% of all oral fibrotic proliferations. Compared to traumatic fibroma, giant (traumatic fibroma or irritation fibroma) cell fibroma occurs at a younger age. In about 60% of the cases the lesion is diagnosed within the first three decades of life and is slightly more in women. 50% of the cases is observed in the gum and will appear as a nodule with a papillary surface . The giant cell fibroma is treated by conservative excisional surgery and recurrence of the lesion is rare .The importance of the reported case is a smooth-surfaced giant cell fibroma associated with a 58-year old man with chronic irritation in the lower lip (Fig. 1).
