Which lesion originates from salivary gland tissue ?
Show answer Hide answer
Answer: A. Acinic cell carcinoma
Explanation
Acinic cell carcinoma is a primary malignant neoplasm originating from salivary parenchymal tissue. Serous acinar cell differentiation characterizes this distinct low-grade salivary gland malignancy. Tumor cells closely mimic normal serous cells found in major salivary glands. Salivary gland tumors can arise within the parotid, submandibular, or minor oral glands. Malignant salivary neoplasms display varied clinical behaviors ranging from low to high grade. Histopathological analysis identifies cytoplasmic zymogen granules within the neoplastic acinar cells.
Pathologists evaluate salivary biopsies to differentiate benign adenomas from malignant carcinomas. Surgical parotidectomy with facial nerve preservation is the standard treatment approach. Patients benefit from early detection because low-grade carcinomas have favorable prognoses. Granular cell myoblastoma is a neural tumor originating from Schwann cell elements. Chondrosarcoma is a malignant bone and cartilage tumor lacking salivary gland parenchymal origin. All options are incorrect because not every listed pathology arises from salivary tissue.
