Dual lesions: a diagnostic dilemma.

Area of Science:

• Oral and Maxillofacial Pathology
• Developmental Jaw Cysts
• Neoplastic Mimics

Background:

• Glandular odontogenic cyst (GOC) is an uncommon, aggressive developmental cyst of the jaw.
• GOC typically affects the anterior mandible in middle-aged individuals and exhibits a high recurrence rate.
• Histopathological differentiation of GOC from other cystic lesions and low-grade central mucoepidermoid carcinoma (CMEC) can be challenging.

Purpose of the Study:

• To highlight a rare case of GOC presenting diagnostic complexities.
• To discuss the differential diagnosis between GOC and CMEC, particularly in unusual locations.
• To emphasize the importance of advanced imaging and thorough histopathological evaluation in resolving diagnostic dilemmas.

Main Methods:

• Case report detailing clinical presentation, advanced imaging (e.g., CBCT), and histopathological analysis.
• Comparative analysis of GOC and CMEC histopathological features.
• Review of relevant literature on GOC and CMEC diagnostic challenges.

Main Results:

• The case involved a GOC in a rare location (maxilla) presenting as distinct clinical entities on the same side.
• Advanced imaging revealed continuity between the clinically separate lesions.
• Histopathological examination confirmed GOC and CMEC, underscoring the diagnostic overlap and perplexity.

Conclusions:

• The maxilla is an uncommon site for GOC, further complicating diagnosis.
• The close histopathological resemblance between GOC and CMEC poses a significant diagnostic challenge.
• Multimodality diagnostic approaches, including advanced imaging and expert histopathological review, are crucial for accurate diagnosis and management of these rare jaw lesions.
