Overview

Acinic cell carcinoma is a head and neck tumor happening in the salivary glands. If a patient was observed with related signs, the tumor must be classified as a benign or invasive by the capsule being intact. Differential diagnosis of a malignant tumor in the salivary gland is made after the incision and by histology features which will provide a good chemotherapy regimen for so-called patients.

Differentiating acinic cell carcinoma from other Diseases

Category	Diseases		Benign/ Malignant	Clinical manifestation					Paraclinical findings			Gold standard diagnosis
				Demography	History	Symptoms	Signs		Lab findings	Histopathology	Imaging
				Demography	History	Pleomorphic adenoma^[1]^[2]	Benign	More common in females Incidence increase with age Incidence: 2-3.5 cases per 100,000 population	Lab findings	Histopathology	Imaging		History of swelling Dysphagia Hoarseness	−	+	Palpable mass of deep lobe of parotid gland Firm Mobile	−	−	Proliferation of epithelial cells and stromal matrix in the ducts	MRI: Homogenous on T1 Abundant myxochondroid stroma on T2	Biopsy	−

Differentiating acinic cell carcinoma from other diseases on the basis of histology findings

On the basis of histologist findings acinic cell carcinoma must be differentiated from other salivary and head and neck masses such as salivary metastasis of thyroid carcinoma, salivary oncocytoma, mucoepidermoid carcinoma, Mammary analog secretory carcinoma.^[10]^[11]


Diseases	Histological findings
Diseases	Overlapping features	Distinguishing features
Salivary metastasis of thyroid carcinoma^[12]	Empty appearance, grooves, pseudoinclusions	Immunohistochemistry (Thyroglobulin)
salivary oncocytoma^[13]	Eosinophilic, non-serous cells	Hematoxylin
mucoepidermoid carcinoma^[14]	Microcystic, and follicula, inconspicuous mucous/squamoid cells, eosinophilic	Immunohistochemistry for p63
Mammary analoge secretory carcinoma^[15]	Histologically similar	Lack of PAS-positive secretory granules, Vimentin positive, Adipophilin positive
