Parotid Secretory Carcinoma: A Distinct Entity from Acinic Cell Carcinoma
摘要
Secretory carcinoma of the salivary gland is a newly recognized entity that is frequently mistaken for acinic cell carcinoma because of their similar morphological characteristics.
Case ReportThis report describes a young adult presenting with a painless preauricular mass, which was initially diagnosed as acinic cell carcinoma based on fine needle aspiration cytology. Following a superficial parotidectomy, the final histopathological examination confirmed the diagnosis of secretory carcinoma.
DiscussionThe diagnosis of salivary gland tumours remains complex due to the wide morphological diversity of these glands, resulting in frequent changes to their classification and terminology. Differentiating secretory carcinoma from acinic cell carcinoma remains particularly challenging because of their overlapping histological features.
ConclusionSecretory carcinoma represents a distinct variant of salivary gland cancer that necessitates thorough histopathological assessment for accurate diagnosis. Complete surgical excision, with or without adjuvant therapy, continues to be the primary treatment approach.
