Summary
Multicentric squamous odontogenic tumors in siblings suggest a possible familial link, challenging the notion of this rare odontogenic neoplasm being solely sporadic. This finding may indicate a reactive hyperplasia or hamartoma rather than a true neoplasm.
Area of Science:
- Oral pathology
- Odontogenic neoplasms
- Genetics in dentistry
Background:
- Squamous odontogenic tumor (SOT) is a rare benign odontogenic neoplasm.
- Previous literature has not suggested a familial predisposition for SOT.
- Multicentric occurrence of SOT is uncommon.
Observation:
- Presents three cases of multicentric squamous odontogenic tumor in black siblings.
- One of the presented cases was previously reported.
- Reviews literature, identifying 5 of 26 previously recorded cases with multiple sites.
Findings:
- The familial occurrence in siblings challenges the typical understanding of SOT.
- Suggests multicentric SOT might represent reactive hyperplasia or hamartoma of residual odontogenic epithelium.
- Highlights the potential genetic or hereditary component in certain SOT presentations.
Implications:
- Re-evaluation of the classification and etiology of multicentric SOT is warranted.
- Consideration of genetic factors in the differential diagnosis of SOT, especially in familial cases.
- Informs clinical management and prognosis for patients with multicentric SOT.
