Summary
This study reports a rare case of ameloblastic fibroma featuring ghost cells and calcifications without features of a calcifying odontogenic cyst. This finding expands the understanding of odontogenic tumor variations.
Area of Science:
- Oral Pathology
- Odontogenic Tumors
- Histopathology
Background:
- Ameloblastic fibroma is a rare odontogenic tumor.
- Ghost cell differentiation is uncommon in ameloblastic fibromas and typically associated with calcifying odontogenic cysts.
Observation:
- A case of ameloblastic fibroma with focal ghost cells and calcifications is presented.
- The patient was a 13-year-old boy with a mandibular swelling.
- Radiographs revealed a multilocular radiolucency associated with an unerupted tooth.
Findings:
- Microscopic examination showed an ameloblastic fibroma with odontogenic epithelial and ectomesenchymal components.
- Focal ghost cells and calcifications were observed within neoplastic epithelial islands.
- Histologic features of a calcifying odontogenic cyst were absent.
Implications:
- This case highlights a rare variant of ameloblastic fibroma.
- It expands the differential diagnosis for odontogenic tumors with ghost cell differentiation.
- Further research may clarify the pathogenesis and behavior of such lesions.

01:09Introduction to Fibroblasts
Rudolph Virchow discovered spindle-shaped cells called fibroblasts in 1858. Inactive fibroblasts, called fibrocytes, become activated by various stimuli, such as growth factors and inflammatory cytokines. Activated fibroblasts play a crucial role in wound healing, inflammation, formation of new blood vessels, and cancer progression. Uncontrolled activation of fibroblasts results in fibrosis, the excess deposition of fibrous tissue, which can lead to scarring and affect normal organs. This...
01:30Bone Cells and Tissue
Bones contain a relatively small number of cells entrenched in a matrix of organic and inorganic components. Although bone cells compose only a small amount of the bone volume, they are crucial to its function. Four types of cells are found within the bone tissue— osteoblasts, osteocytes, osteogenic cells, and osteoclasts.
Osteoblasts and Osteocytes
The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the periosteum and...
