“…36 Meanwhile, it is necessary to recognize that other non-neoplastic lesions of the parotid gland may also be accompanied by lymphadenopathy, such as kimura's disease and tuberculosis. 37 At present, PSP is the most common surgical procedure for PAs. While malignant epithelial tumors often need facial nerve rehabilitation management performed together with the oncological surgery.…”

The aim of this study was to explore and validate the diagnostic performance of whole-volume CT texture features in differentiating the common benign and malignant epithelial tumors of the parotid gland. Materials and Methods: Contrast-enhanced CT images of 83 patients with common benign and malignant epithelial tumors of the parotid gland confirmed by histopathology were retrospectively analyzed, including 50 patients with pleomorphic adenoma (PA) and 33 patients with malignant epithelial tumors. Quantitative texture features of tumors were extracted from CT images of arterial phase. The diagnostic performance of texture features was evaluated via receiver operating characteristic (ROC) curve and area under ROC curve (AUC). The specificity and sensitivity were respectively discussed by the maximum Youden's index. Results: All the texture features were subject to normal distribution and homoscedasticity. Energy, mean, correlation, and sum entropy of epithelial malignancy group were significantly higher than those of PA group (P<0.05). There were no statistically significant differences between PA group and epithelial malignancy group in uniformity, entropy, skewness, kurtosis, contrast, and difference entropy (P>0.05). The AUC of each texture feature and joint diagnostic model was 0.887 (energy), 0.734 (mean), 0.739 (correlation), 0.623 (sum entropy), 0.888 (energy-mean), 0.883 (energy-correlation), 0.784 (mean-correlation). The diagnostic efficiency of energy-mean was the best. Based on the maximum Youden's index, the specificity of energy-correlation was the highest (97%) and the sensitivity of energy was the highest (97%). Conclusion: Energy, mean, correlation, and sum entropy can be the effective quantitative texture features to differentiate the benign and malignant epithelial tumors of the parotid gland. With higher AUC, energy and energy-mean are superior to other indexes or joint diagnostic models in differentiating the benign and malignant epithelial tumors of the parotid gland. CT texture analysis can be used as a noninvasive and valuable means of preoperative assessment of parotid epithelial tumors without additional cost to the patients.

“…[ 6 ] The intraglandular lymph nodes’ involvement is more common. [ 3 11 ] The salivary gland register (1965–1981) contains only 2 cases of parenchymatous tuberculosis of the parotid gland. However, it contains 46 cases of intraglandular or periglandular lymph node involvement.…”

Tuberculosis being endemic in country like India can affect any organ though pulmonary tuberculosis is rampant and extrapulmonary is rare. Tuberculosis affecting parotid gland is a rare occurrence, usually unilateral. However, Mycobacterium tuberculosis causing cold abscess in bilateral parotid glands is even rarer. Here, we present a case of a young female presented with bilateral slow-growing swelling in the parotid region with evening raise of temperature for two months. On clinical examination, no signs of inflammation were seen. Ultrasonography showed thick-walled hypoechoic collection with septae and internal echoes within involving both superficial and deep lobes of the parotid gland. Fine-needle aspiration cytology (FNAC) suggested a caseating granuloma and acid fast bacilli were detected on ZN staining, thereby confirming the diagnosis of cold abscess. She was put on antitubercular drugs and there was a drastic reduction in the size of swelling.

“…Axillary or inguinal lymph node tuberculosis, also called scrofula in traditional Chinese medicine (TCM), of which the pathogen is mycobacterium tuberculosis. [ 10 , 11 ] Initially, enlarged lymph nodes are hard, painless and movable. The course of this disease continues to develop and perilymphadenitis may occur.…”

Rationale: Accessory breast cancer is extremely rare among all cancerous diseases, especially in male patients. There were only few male axillary accessory breast cancer cases that have been reported in scientific literatures so far. Hereby, we would like to discuss a case of male axillary accessory breast cancer found in our hospital. Patient concerns: We report a male senile patient suffering from a painful, enlarged, and hardened right axillary mass for more than 20 years. He came for further treatments due to progressive growth of the mass for 11 months with bloody ulceration for more than 1 month. Diagnosis: Pathological examination manifested a grade II infiltrating ductal carcinoma derived from the accessory mammary gland (right axilla), with invasion of local skin. Immunohistochemical examination result: estrogen receptor (++) 90%, progesterone receptor (+++) 100%, human epidermal growth factor receptor-2 (1+), ki67 (20% positive), prostate specific antigen (−), caudal-related homeobox-2 (−), thyroid transcription factor-1 (−), Synaptophysin (+), NapsinA (1), and CK7 (−). Interventions: Modified radical mastectomy and axillary lymph nodes clearance were performed on the accessary breast cancer under general anesthesia. Postoperatively, endocrine therapy was provided for the patient, orally-taken Letrozole was recommended for the rest of the patient's life. Outcomes: The patient recovered uneventfully and was discharged 3 days after the operation. The patient continued to take Letrozole orally regularly at home and no signs of recurrence were observed. Conclusion: Axillary accessory breast cancer in males is extremely rare, with no conspicuous and typical clinical presentations, which leads to inevitable neglect by clinicians. Therefore, there is significant necessity for clinicians to be cautious with this type of disease.
