Abstract Introduction/Objective Warthin tumor-like mucoepidermoid carcinoma(WTL- MEC) is one of the subvariant of mucoepidermoid carcinoma. It mimics the histological features of metaplastic Warthin tumors (mWTs). To investigate the clinicopathological, molecular features, and bio-behaviors of WTL-MEC, we retrospected a cohort of 29 WTL- MEC patients. Methods/Case Report The clinicopathological and microscopic data were collected. Dual-color FISH analysis was performed on paraffin-embedded sections of 29 WTL- MEC patients and 16 mWTs patients using a MAML2 break- apart probe. Whole-exome sequencing and whole transcription sequencing were performed on 3 WTL-MEC and 3 typical mucoepidermoid carcinomas (TMEC) patients. Genetic data were bioinformatically analyzed by software MuTect (v1.7), PINDEL (v0.2.5), SnpEff (v3.0), and etc. Results (if a Case Study enter NA) The cohort of WTL-MEC included 10 male and 19 female patients with a median age of 42.3 years (range, 8 to 68 years). Microscopically, the WTL-MEC lesion consisted of multi-cysts with variant shapes and sizes. The cystic spaces were lined by bi-layered and multilayered oncocytic cells. A transition zone between the bi-layered oncocytic epithelium to the multilayered oncocytic epithelium was observed in WTL-MEC. The cords of epidermoid cells and mucous cells could be found. The germinal center, extensive hyalinization, and mucus extravasation were observed. MAML2 rearrangement was identified in 29 (100%) WTL-MEC. No rearrangement was observed in mWTs by FISH. MET was the most commonly mutated gene in TMEC, and PRDM11 was the most commonly mutated gene in WTL-MEC. Twenty-nine patients were alive without recurrent at the end of the follow-up periods(5–128M). One Patient died due to the metastasis to the lung. Conclusion compared with mWTs, WTL- MEC usually presented in the young, non-smoking female. The histological feature of WTL-MEC depended mainly on the transition zone of the bi-layered oncocytic epithelium and the multilayered oncocytic epithelium. And MAML2 status can confirm the diagnosis. CRTC1-MAML2 and PRDM11 mutations appear to be the main driver event of WTL-MEC. Prognosis was usually favorable, but recurrence or metastasis may rarely occur.

Abstract The treatment of multiple myeloma (MM) continues to evolve with new drugs, resulting in dramatically improved outcomes. Despite these advances, MM remains an incurable disease, with Extraosseous/Extramedullary disease (EMD) playing a major role in the development of relapsed refractory disease. EMD is defined by the development of plasma cell neoplasms that arise in tissues other than bones. EMD can present at diagnosis or develop during the disease course of MM. Sometimes EMD can be solitary without bone marrow (BM) involvement. Determining the molecular underpinnings of EMD are critical to advance the care of such patients. A few reports suggest a possible role of Ras mutations in the intramedullary to extramedullary transition in a limited number of patients. Therefore, the molecular biology of developing EMD has not yet been clearly defined. We sought to identify molecular features of EMD and associated these with clinical outcomes. We analyzed samples from 443 MM patients who presented to Massachusetts General Hospital between 2013 and 2021. All patients voluntarily signed informed consent approved by the institutional review board for SNaPshot (molecular) testing. BM aspirate, biopsy and EMD tumor specimens underwent pathological analysis as well as FISH testing. The diagnosis of EMD was determined by either CT, PET-CT or MRI done as part of their clinical course. In some cases, EMD was confirmed by biopsy. Although there were some cases of EMD adjacent to bones, we strictly defined EMD as non-adjacent to bones based on imaging. Nucleic acids were extracted from BM and EMD samples obtained from MM patients. Multiplexed mutational analysis was done with primers designed to cover 111 genes including genes known to be oncogenic. SNaPshot was done and the threshold for allele frequencies was determined as 8% based on our laboratory cut-offs. The median follow-up of the entire MM population was 63.7 months (range 1 to 408). Overall, 96 of 443 patients (21.6%) developed EMD as previously defined. Sixty-five out of 96 patients had biopsy confirmed EMD, while 31 patients were diagnosed by imaging only. SNaPshot molecular testing was performed on 30 EMD samples from the 65 patients who had biopsies. Interestingly, all EMD samples except for 1 had either NRAS, KRAS, or BRAF mutations. There were 14 EMD samples with NRAS mutations, 6 with KRAS mutations, 4 with BRAF mutations, and 1 with both KRAS and BRAF mutations. All BRAF mutations coexisted with other mutations, such as TP53, ATM, and ARID1A whereas some of the NRAS and KRAS mutations were observed alone. Next SNaPshot was analyzed for 8 paired BM and EMD samples. Three BM samples were negative for NRAS mutations while all EMD samples were positive. Patients with KRAS/NRAS/BRAF mutations who developed EMD had poorer prognosis than non-EMD patients with KRAS/NRAS/BRAF mutations. In patients with KRAS mutations, the median overall survival (OS) was 36.9 months (EMD) vs not reached (non-EMD) (p<0.01); and BRAF mutations, the median OS was 58.5 months (EMD) vs 112.4 months(non-EMD) (p=0.194). In patients with NRAS mutations, the median OS was 94.5 months(EMD) vs 124.5 months (non-EMD) (p=0.11). Average time from diagnosis of MM to developing EMD in 68 patients with longitudinal follow up was 41.6 months and average time from developing EMD to death in 54 patients with longitudinal follow-up was 7.6 months. There were significant differences in BM FISH analysis in KRAS/NRAS/BRAF mutation harboring EMD vs non-EMD; Chromosome 1 abnormalities (79.2% vs 34.2%), TP53 deletion (41.7% vs 22.4%) and hyperdiploidy (37.5% vs 67.1%). Our data suggest that KRAS/NRAS/BRAF mutations may play an important role in the development of EMD. These and other associated molecular abnormalities portend a poorer prognosis and may provide novel therapeutic insights.

Mucoepidermoid carcinoma (MEC) shows a wide morphologic spectrum, including epithelium with oncocytic or squamous metaplastic changes overlying a prominent cystic architecture, as well as tumor-associated lymphoid tissue. We illustrate a case of MEC of the parotid in a 17-year-old female, in which all these features occurred extensively, such that they accounted for almost the entire neoplasm, and closely mimicked Warthin tumor histologically. This highlights the need for diagnostic awareness of this particular morphologic variant of MEC, as patients could potentially be inappropriately discharged from follow-up if diagnosed with a benign neoplasm.

Neuroblastoma (NB) is the most common extra-cranial malignancy in preschool children. To portray the genetic landscape of an overly aggressive NB leading to a rapid clinical progression of the disease, tumor DNA collected pre- and post-treatment has been analyzed. Array comparative genomic hybridization (aCGH), whole-exome sequencing (WES), and pharmacogenetics approaches, respectively, have identified relevant copy number alterations (CNAs), single nucleotide variants (SNVs), and polymorphisms (SNPs) that were then combined into an integrated analysis. Spontaneously formed 3D tumoroids obtained from the recurrent mass have also been characterized. The results prove the power of combining CNAs, SNVs, and SNPs analyses to assess clonal evolution during the disease progression by evidencing multiple clones at disease onset and dynamic genomic alterations during therapy administration. The proposed molecular and cytogenetic integrated analysis empowers the disease follow-up and the prediction of tumor recurrence.

Paranasal mucoceles are a type of cysts that evolve slowly and are asymptomatic; this poses a difficulty in diagnosing the patient because the symptoms can go unnoticed. The mucocele evolves unpredictably. On the one hand, it can become infected turning into pyoceles and on the other hand, it can invade important regions such as the orbital, cranial or genian regions, creating facial asymmetry. This is a retrospective case study of 37 patients diagnosed with sinus mucoceles, followed up by clinical examination and paraclinical tests such as CT and MRI scans. The biochemical components of the liquid from within the mucocele were analyzed and the following criteria were recorded: NaCl-, Cl-, Na+ and cholesterine as well as cellular components such as mastocytes, macrophages, hematocytes and leucocytes. In all cases, the treatment option was surgery with favorable post-operative and follow-up evaluation. The mucoceles that appeared post-operatively (maxillary and ethmoid sinuses) evolved more rapidly than the mucoceles that were induced byan external injury. Longer follow-up of operated patients permitted a more timely diagnosis of recurrences.

This paper is a follow-up article based on the first article titled Customers speak for themselves: A case of Customer Satisfaction in the four Main South African Banks. Customer satisfaction within the banking industry is very important in the South African context. Although banks are trying their best to give their customers the best service, it is important to continuously measure customer satisfaction and identify service attributes that contribute to overall customer satisfaction for the banks. The data used in the analysis is based on a quantitative survey of 500 randomly selected customers in Pretoria, Johannesburg, Durban and Cape Town were interviewed using a face to face methodology. The key drivers of overall customer satisfaction based on regression analysis for the different banks were helpfulness and innovativeness (ABSA), helpfulness, innovativeness of the bank, resolution of problems and investment advice (FNB), language usage and friendliness of service consultants (Nedbank), innovativeness of the bank, investment advice and use of language (Standard bank). These attributes were important to the overall customer satisfaction and need to be closely monitored by the management of these banks.
