Mohammad DN, Ibraheem BF, Khudair HH, Mahmood DK. Int J Gen Med. 2023;16:823–835. It has come to our attention that Figure 1 on page 827 is incorrect. An error during the preparation of Figure 1 for publishing led to the inadvertent creation of duplicate features, parts A-F were duplicated from Figure 2A–F. The journal wishes to apologise for this error. The correct version of Figure 1 is as follows. Figure 1 Continued. Figure 1 Syndecan-1 immunoexpression in benign and malignant salivary tumors. (A) Score 3 immunoexpression in ductal and myoepithelial cells of pleomorphic adenoma X40. (B) Mixed intra cellular localization in pleomorphic adenoma X40. (C) Mixed intracellular localization in bilayered epithelia of warthin tumor X40. (D) Score 3 expression and mixed intracellular localization in cribriform adenocystic carcinoma X40. (E) Score 3 immunoexpression and mixed localization of both epidermoid and mucous cells in mucoepidermoid carcinoma X40. (F) Capsular invasion of both acinar and ductal cells in acinic cell carcinoma X10. (G) Muscle invasion of acinar and ductal cells in acinic cell carcinoma X10.

They are considered a problematic area in diagnosis due to complex clinicopathological features and different biological behavior.Objective: To identify the pathological behavior of salivary tumors immunohistochemically.Methodology: This retrospective study involved thirty formalin-fixed paraffin-embedded blocks of salivary gland tumors. These tumors were stained immunohistochemically with syndecan-1 and cyclin D1. Chi-Square test was used to relate immunoscoring, intracellular localization, intensity, and invasion to different salivary tumors. The correlation of these two markers was done by spearman‘s rho test. P-value < 0.05 was considered statistically significant.Results: The mean age of the patients was 48.69 ± 17.7. The parotid gland was the most commonly reported site in benign tumors, and regarding malignant tumors, maxilla was the most prevalent site. Syndecan-1 in benign tumors showed a predominate score 3, most widely detected in pleomorphic adenoma. Malignant salivary tumors showed 89.4% positive expression with a more frequent score 3, most commonly found in adenocystic carcinoma. Cyclin D1 expressed in all benign salivary tumors, with prominent diffuse mixed intracellular localization in pleomorphic adenoma. Malignant tumors revealed an expression of 94.7%. Moderate scoring with mixed intracellular localization was recorded in adenocystic carcinoma, followed by mucoepidermoid carcinoma. There was a significant correlation between the two markers
