Table 1: Comparison of clinical and microscopic findings of the four entities most likely to be listed in the differential diagnosis of the lesion
NAME | CLASSIFICATION | SHAPE | COLOR | AGE (F > M) | MICROSCOPIC APPEARANCE | USUAL LOCATION |
PERIPHERAL ODONTOGENIC FIBROMA (P Od F) | Subtype of Peripheral Fibroma (Akin to POF) | P; S | Pink | Mean 29 | Strands of Odontogenic Epithelium (Possibly Calcifications) | Mandible>Maxilla Anterior Gingiva F > M |
PERIPHERAL GIANT CELL GRANULOMA (P G C G) | Giant Cell Epulis ( = 'Periph.Giant Cell Reparative Gran' - Jaffe) [Resembles Pyog.Gran.. or.. Periph Odont Fibroma (!)] | P;S | Dark Red to Purplish | 48% = Child Bearing Age | Giant Cells Capillary Hemosiderin | Mandible > Maxilla Gingiva, anterior to Molar Teeth. F = M |
PYOGENIC GRANULOMA (P G) | May be Early Stages of P Od F, P Oss F, P G C G | P;S | Red (usually Ulcerated) | Pregnant or Adoles cent | Fibrous Conn Tissue Heavily Vascularized Many Capillaries | Maxilla > Mandible Gingiva; Lips; Tongue; (Mucous Menbranes) Occ: Skin F >> M |
PERIPHERAL OSSIFYING FIBROMA (P O F) | Subtype of Peripheral Fibroma (Akin to P Od F) | P;S | Pink | 5 - 25 Mean 30 | Fibroblasts c. Ossifying (and possibly Odontogenic) Rests | Body of Mandible, but, usually: Maxilla>Mandible F = M |
