Abstract
BACKGROUND Colon cancer is one of the most common diagnosed malignancies. Despite the use of surgery, chemotherapy, radiotherapy, targeted therapy, immunotherapy, and other comprehensive treatments, distant metastasis is still one of the main causes for dying of colon cancer. The common metastatic site of colon cancer is the liver, lung, and bone. In this article, we report a rare case of breast metastasis of signet ring cell carcinoma from the colon. CASE PRESENTATION A 44-year-old woman was diagnosed with colon cancer and received a radical surgery of colon cancer in 2019. Combined with postoperative pathological and computed tomography (CT) images, a diagnosis of cT3N2M0 mucinous adenocarcinoma of colon (according to AJCC cancer staging manual, Version 8) was established. Adjuvant chemotherapy (XELOX: oxaliplatin 130 mg/m2 on day 1 plus capecitabine 1000 mg/m2 twice daily on days 1 to 14 every 3 weeks for 18 weeks) was performed followed by surgical resection. Fourteen months later, the patient underwent mastectomy for breast mass, which was diagnosed pathologically as metastasis of signet ring cell carcinoma from the colon. XELOX chemotherapy regimen (oxaliplatin 130 mg/m2 on day 1 plus capecitabine 1000 mg/m2 twice daily on days 1 to 14 every 3 weeks for 24 weeks) combined with bevacizumab (7.5 mg/kg on day 1) was used after the mastectomy. The patient had stable disease according to her last examination (RECIST criteria). CONCLUSION It is rare to find a report of a patient of colon cancer that metastasizes to breast. We hope to increase treatment experience for patients with this rare metastasis.

Abstract
Purpose: This study aimed to investigate the prognostic factors of patients with lymphoepithelioma-like carcinoma of the urinary bladder (LELCB) and explore the value of surgical treatment. Methods: Data of patients with LELCB were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. The multivariate analysis was performed using the stepwise Cox proportional hazards regression model and conditional inference tree method to identify significant prognosticators of overall survival (OS) from the parameters such as age, gender, lymph node involvement, tumor extent, radiation, chemotherapy, and surgery type. Literature review (LR) was performed, and eligible cases were used to validate prognostic classification using the Kaplan-Meier method with log-rank tests. Results: Sixty patients with a median age of 69.5 years were identified from the SEER database and 91 patients through LR. The Cox analysis identified age, gender, lymph node involvement, and surgical approach as independent prognosticators of OS. Based on the nomogram scores, patients were stratified into three prognostic groups: (I) patients younger than 70 years; (II) patients older than 70 years, who received bladder-sparing therapy (BST); and (III) patients older than 70 years undergoing radical cystectomy (RC). Patients in group II had the worst outcomes in terms of OS compared with patients in groups I and III (p < 0.001 and p = 0.03, respectively). A similar survival pattern was found in the LR cohort. Conclusion: The nomogram provided individualized prognostic quantification of OS in patients with LELCB. BST could yield favorable outcomes when treating LELCB, especially for younger patients, whereas older patients might derive more survival benefit from RC.

Abstract
BACKGROUND AND PURPOSE The WHO recently designated salivary gland lymphoepithelial carcinoma as a unique malignant tumor that most commonly occurs in the parotid gland. This is a rare cancer and there are few reports in the literature. Among 854 patients with parotid gland tumors who were admitted to our institution, we diagnosed 12 patients (1.41%) with parotid lymphoepithelial carcinoma. METHODS Retrospective analysis of 12 patients with parotid lymphoepithelial carcinoma diagnosed by the Department of Pathology, Xiangya Hospital of Central South University. RESULTS All 12 patients had unilateral parotid gland disease and 8 had cervical lymph node metastasis. Five patients received PCR testing for the Epstein-Barr virus and two were positive. All patients received surgical treatment, two received surgical resection alone, nine received surgery and postoperative radiotherapy and chemotherapy, and one received surgery and postoperative chemotherapy. The postoperative follow-up time ranged from 13 to 77 months. As of the last follow-up, eight patients were tumor-free, one patient was lost to follow-up, and three patients died. The main cause of death was local tumor recurrence and multiple metastases throughout the body. CONCLUSION Parotid lymphoepithelial carcinoma is a malignant neoplasm characterized by proliferation, invasion, and inclusion of poorly differentiated or undifferentiated carcinoma, and a high rate of metastasis to ipsilateral cervical lymph nodes. The comprehensive treatment method consists of radical resection combined with postoperative radiotherapy and chemotherapy. After this comprehensive treatment, the 1-year, 3-year, and 5-year overall survival rates of our patients were 100%, 78.8%, and 39.4%.

Abstract
Lymphoepithelial carcinoma (LEC) shows characteristic histology of nesting growth of tumor cells with unclear differentiation against the lymphoid stroma background. Although rare in salivary glands, it has previously been recognized as a type of undifferentiated carcinoma but is currently clearly defined as an independent disease separate from undifferentiated carcinoma. We report a case of LEC that developed in the parotid gland and was immunohistochemically positive for p16, which suggested the causative involvement of human papillomavirus (HPV). The patient was a 38-year-old Japanese male aware of mass formation in the left parotid area for 8 years. Parotidectomy was performed and there have been no signs of recurrence or metastasis for 18 month post-operation. The tumor was histologically typical except for Epstein-Barr virus (EBV)-encoded small RNA (EBER)-negative in situ hybridization (ISH), but p16-positivity by immunohistochemistry, and also frequent contact with extended and expanded pre-existing ductal structures. Although usually strongly associated with EBV infection, the tumor could be regarded to have eventually reached completion as a LEC lesion associated with HPV infection possibly through the pathway shared with squamous cell carcinoma. EBER-ISH remains the most promising index for confirming diagnosis of LEC, but EBV-negative result alone should not prevent diagnosis of LEC.

Abstract
Lymphoepithelial carcinoma of salivary glands (LECSG) is an uncommon neoplasm. This article summarizes the findings of 438 cases in a review of the literature. Concurrent lymphoepithelial lesions may suggest a primary tumor. The tumor shows a nonkeratinizing carcinoma intimately associated with a rich lymphohistiocytic infiltrate, destroying adjacent salivary gland tissue. Irrespective of race or ethnicity, the tumors usually express Epstein-Barr virus, with Epstein-Barr virus encoded small RNA (EBER) and/or latent membrane protein-1 (LMP-1), although a subset does not. There is an overall good prognosis of about 80% at 5 years.

Abstract
A high index of suspicion is required for primary parotid lymphoepithelial cancer in Caucasians with a pre-auricular mass. LEC can afflict patients of any ethnicity in Epstein-Barr Virus non-endemic areas. LEC of the parotid gland is a rare entity that requires complete surgical resection and post-operative radiation therapy.
Background Lymphoepithelial carcinoma (LEC) of the salivary glands is a rare, but distinct, poorly-differentiated neoplasm that resembles undifferentiated nasopharyngeal carcinomas (NPC). Among primary salivary gland LECs, they most commonly arise in the parotid gland. These lesions have a noticeable racial predilection, mostly occurring in Asians and Arctic region native populations. They are strongly associated with Epstein-Barr virus (EBV), and are more common in EBV-endemic areas. The most common presenting symptoms of primary parotid LEC are parotid mass development and cervical lymphadenopathy. We report an unusual case of EBV-negative LEC in a Canadian Caucasian woman. Case presentation A 40-year-old female from Atlantic Canada presented with a rapidly enlarging preauricular mass and cervical lymphadenopathy. Preoperative diagnostics via radiology and fine needle aspiration alluded to an ambiguous primary parotid malignancy. She underwent a total parotidectomy with facial nerve sacrifice and ipsilateral selective neck dissection. The facial nerve was reconstructed with a lateral antecubital nerve graft. Pathology came back positive for LEC, and she began adjuvant radiotherapy. At her 1-year follow up, she was disease-free and obtained a House-Brackmann facial nerve function grade of 3. Conclusions The case report highlights the importance of having a high index of suspicion and the need for interdisciplinary collaboration in reaching the diagnosis of primary parotid LEC. LEC can afflict patients of any ethnicity in non-EBV endemic areas and should therefore be considered in all patients with a painless parotid mass regardless of ethnicity. Further studies are required to elucidate the oncogenic role of EBV in these cancers.

Abstract
Lymphoepithelial carcinoma of salivary glands (LECSG) are rare neoplasms, reported in endemic populations (southeastern Chinese) with a strong Epstein-Barr virus (EBV) association. A retrospective series comparing EBV status within an ethnically diverse population (endemic vs. non-endemic patients) has not been reported. Sixteen LECSG were equally distributed between males (n = 8) and females (n = 8) with a median age of 54 years (range 18 to 85 years) at initial diagnosis. Ten patients were white, 4 Asian, and 2 black. The patients typically presented with swelling or mass for an average of 11.6 months. Tumors affected only major salivary glands: parotid (n = 13); submandibular (n = 3). Tumors were an average of 2.9 cm (range 1.5 to 5.8 cm). Nine of 16 (56%) patients had cervical lymph node metastases at presentation. No patients had nasopharyngeal or oropharyngeal tumors. Microscopically, the tumors were widely infiltrative, characterized by large polygonal to spindled cells arranged in a syncytial, lattice-like network in a background of lymphoplasmacytic cells. The neoplastic cells showed an open-vesicular nuclear chromatin to a more basaloid-morphology, the latter showing hyperchromatic nuclei and less cytoplasm, while nearly all of the cases had associated lymphoepithelial lesions/sialadenitis. By in situ hybridization, 8 of 16 cases had a strong, diffuse EBER expression (4 of 4 Asians; 4 of 12 non-Asians), while with immunohistochemistry all cases tested were pan-cytokeratin, CK5/6 and p63 reactive; none of the cases tested were p16 reactive. All patients were managed with wide or radical excision, 4 with concurrent chemoradiation, and 6 with radiation alone. Distant metastasis (lung, brain, and bone) developed in 2 patients. Overall follow-up (mean 3.8 years) revealed 12 patients alive and 2 dead, none with evidence of disease (mean 4.3 years); one white male alive with disease at 1.9 years, and one Asian female dead of disease at 4.2 years; both of these latter patients had Group IV stage disease. High stage (Group IV) patients had a shorter mean survival than lower stage patients: 3.1 versus 4.8 years, respectively. In conclusion, LECSG are uncommon primary neoplasms. Concurrent lymphoepithelial lesions may help suggest a primary tumor. The tumors, irrespective of race or ethnicity, may express EBER. There is an overall good survival, perhaps better for EBV-negative patients and for those with lower stage disease.

Abstract
OBJECTIVE To investigate and analyze the typical CT findings of salivary gland lymphoepithelial carcinoma. METHODS CT findings in 8 patients with lymphoepithelial carcinoma (LEC) in salivary gland were studied retrospectively. Surgical resection was performed in all cases. RESULTS 8 cases were subdivided to primary tumor and secondary tumor. In primary tumor group, 5 were localized in the parotid gland, 2 were found in the submandibular glands; 6 lesions had with homogeneous density, 1 was associated with cystic degeneration and 1 with calcification; the margins of lesions in 5 cases were poorly defined, while well-defined in 2. On enhanced CT: obvious enhancement was achieved in all of the 7 solitary lesions, among which 4 were homogenously enhanced while the other 3 had heterogeneous enhancement. In the 2 cases of nodules in deep lobe, retromandibular vein was affected; 7 patients had positive Epstein-Barr virus (EBV) test, with Ki-67 measurements ranged from 40% to 80%. 1 patient had LEC secondary to Benign Lymphoepithelial Lesion (BLEL), with involvement of bilateral parotid glands; the lesion was manifested as multiple differently-sized nodules, with partial cystic change, all of the nodules had clear margins, and obvious ring-shape enhancement was seen in the nodules with cystic change; the patient with secondary LEC had negative EBV test and a Ki-67 value of 20%. CONCLUSION In most cases, LEC was primary and occurred in the parotid glands. The probable diagnosis could be made based upon Dual-phase contrast-enhanced CT scan findings combined with positive expression of EBV.

Abstract
BACKGROUND Lymphoepithelioma-like carcinoma (LELC) in the salivary glands is a rare but unique malignancy. METHODS Sixty-nine patients with salivary gland LELC with long-term follow-up were reviewed for this study. RESULTS There were 52 cases in the parotid gland and 17 cases in the submandibular gland. All patients underwent complete tumor excision, 41 underwent neck dissection, and 39 received postoperative radiotherapy. The 5-year, 10-year, and 15-year overall survival (OS) rates were 90%, 75%, and 54%, respectively. Patients with higher neutrophil/lymphocyte ratio (NLR ≥ 4.0) and advanced stage (stage III and IV) had significantly poorer OS. Patients who received postoperative radiotherapy had significantly better relapse-free survival (RFS). In multivariate analysis, stage, NLR, and neck dissection were associated independently with OS, whereas stage and postoperative radiotherapy were associated independently with RFS. CONCLUSION Salivary gland LELC is a rare malignancy with a better prognosis that partially attributes to surgery with neck dissection and postoperative radiotherapy. Preoperative NLR is an independent prognostic factor.

Abstract
BACKGROUND Colorectal cancer metastasis to a mammary location is very rare. CASE REPORT A 38-year-old male, who had undergone anterior resection of an advanced rectal carcinoma 7 years earlier, presented with a right mammary mass. Core needle biopsy of the mass indicated cytology consistent with breast adenocarcinoma. After neoadjuvant chemotherapy and modified radical mastectomy, pathology identified the mass as rectal carcinoma. CONCLUSION The authors highlight the difficulty of making an accurate diagnosis of rectal cancer metastasis to the breast of a male.
