A pigmented odontogenic keratocyst.
The British Journal of Oral & Maxillofacial Surgery
|June 1, 1985
Summary
A rare pigmented odontogenic keratocyst was found in a Caucasian female. Melanocytes were identified in the basal cell layer, indicating a potential new subtype of this jaw cyst.
Area of Science:
- Oral pathology
- Odontogenic cysts
- Histopathology
Background:
- Odontogenic keratocysts (OKCs) are common developmental cysts of the jaw.
- While typically non-pigmented, rare variants may present with pigmentation.
- Understanding OKC variations is crucial for accurate diagnosis and treatment.
Observation:
- This report details a unique case of a pigmented odontogenic keratocyst.
- The cyst occurred in a white Caucasian female patient.
- Histological examination revealed the presence of melanocytes.
Findings:
- Melanocytes were definitively identified within the basal cell layer of the OKC.
- Both light and electron microscopy confirmed the presence and location of these melanocytes.
- This finding suggests a potential melanocyte-derived component or influence in this specific OKC.
Implications:
- This case expands the known spectrum of odontogenic keratocyst presentations.
- The presence of melanocytes may warrant further investigation into the pathogenesis of pigmented OKCs.
- This finding could influence diagnostic criteria and future research into jaw cyst development.
