Sinonasal adenoid cystic carcinomas accompanied by seromucinous hamartoma and/or atypical sinonasal glands arising from seromucinous hamartoma: insight into their histogenesis

Key Points

• Adenoid cystic carcinomas and seromucinous hamartomas may share histogenetic origins, suggesting a relationship.
• Clinically, the presence of atypical sinonasal glands alongside these lesions raises concerns for diagnosis and treatment.
• Histological examination identifies key features of seromucinous hamartomas linked to sinonasal malignancies, aiding in understanding their formation.
• Findings underscore the necessity for further studies on sinonasal gland interactions to clarify their clinical significance.
