Background
Research regarding cervical metastasis from an unknown primary tumor (CUP) according to human papillomavirus (HPV) and Epstein-Barr virus (EBV) status in Korea has been sporadic and small-scale. This study aims to analyze and understand the characteristics of CUP in Korea according to viral and p16 and p53 status through a multicenter study.
Methods
Ninety-five cases of CUP retrieved from six hospitals in Korea between January 2006 and December 2016 were subjected to high-risk HPV detection (DNA in situ hybridization [ISH] or real-time polymerase chain reaction), EBV detection (ISH), and immunohistochemistry for p16 and p53.
Results
CUP was HPV-related in 37 cases (38.9%), EBV-related in five cases (5.3%), and unrelated to HPV or EBV in 46 cases (48.4%). HPV-related CUP cases had the best overall survival (OS) (p = .004). According to the multivariate analysis, virus-unrelated disease (p = .023) and longer smoking duration (p < .005) were prognostic factors for poor OS. Cystic change (p = .016) and basaloid pattern (p < .001) were more frequent in HPV-related cases, and lymphoepithelial lesion was frequent in EBV-related cases (p = .010). There was no significant association between viral status and p53 positivity (p = .341), smoking status (p = .728), or smoking duration (p = .187). Korean data differ from Western data in the absence of an association among HPV, p53 positivity, and smoking history.
Conclusions
Virus-unrelated CUP in Korea had the highest frequency among all CUP cases. HPV-related CUP is similar to HPV-mediated oropharyngeal cancer and EBVrelated CUP is similar to nasopharyngeal cancer in terms of characteristics, respectively.

Abstract PDF

About one-fourth of the global population is either overweight or obese, both of which increase the risk of insulin resistance, cardiovascular diseases, and infections. In obesity, both immune cells and adipocytes produce an excess of pro-inflammatory cytokines that may play a significant role in disease progression. In the recent coronavirus disease 2019 (COVID-19) pandemic, important pathological characteristics such as involvement of the renin-angiotensin-aldosterone system, endothelial injury, and pro-inflammatory cytokine release have been shown to be connected with obesity and associated sequelae such as insulin resistance/type 2 diabetes and hypertension. This pathological connection may explain the severity of COVID-19 in patients with metabolic disorders. Many studies have also reported an association between type 2 diabetes and persistent viral infections. Similarly, diabetes favors the growth of various microorganisms including protozoal pathogens as well as opportunistic bacteria and fungi. Furthermore, diabetes is a risk factor for a number of prion-like diseases. There is also an interesting relationship between helminths and type 2 diabetes; helminthiasis may reduce the pro-inflammatory state, but is also associated with type 2 diabetes or even neoplastic processes. Several studies have also documented altered circulating levels of neutrophils, lymphocytes, and monocytes in obesity, which likely modifies vaccine effectiveness. Timely monitoring of inflammatory markers (e.g., C-reactive protein) and energy homeostasis markers (e.g., leptin) could be helpful in preventing many obesity-related diseases.

Abstract PDF: Systemic Epstein-Barr virus (EBV)–positive T-cell lymphoma of childhood (SETLC) is a rare, rapidly progressive, and often fatal disease of children and young adults characterized by monoclonal expansion of EBV-positive T cells in tissues or peripheral blood following infection with EBV. Its distinction from other EBV-positive T-cell lymphoproliferative disorders with overlapping features can be difficult, and particular diagnostic features may not be manifest until autopsy examination. We present the case of a 10-year-old boy with significant disability due to remote traumatic brain injury following non-accidental head trauma who died unexpectedly at home. Given the history of physical abuse and the potential for homicide charges, significant medicolegal implications arose with this case. Pathologic investigation ultimately revealed conclusive diagnostic features of SETLC including extensive proliferation of EBV-positive T cells in multiple organs. A natural manner of death was confirmed, thereby excluding delayed homicide related to complications of non-accidental head trauma.

Abstract PDF

Eosinophilic ulcer of the oral mucosa (EUOM) is a very rare, benign, self-limiting ulcerative lesion of the oral cavity of unknown pathogenesis, and belongs to the same spectrum of CD30⁺ T-cell lymphoproliferative disease (LPD) of the oral mucosa. The etiology and pathogenesis of the disease are unknown. We report two cases in children who were initially diagnosed with EUOM and CD30⁺ T-cell LPD, respectively. However, retrospective analysis revealed that a majority of infiltrated atypical T cells were positive for Epstein-Barr virus (EBV). The present cases suggest that the pathogenesis and etiology of EUOM or CD30⁺ T-cell LPD occurring in children are different from those in adults. EUOM or CD30⁺ T-cell LPD in children is a manifestation of EBV-positive T-cell LPD, and should therefore be distinguished from the disease in adults.

Abstract PDF

Background

Epstein-Barr virus (EBV)-associated hemophagocytic lymphohistiocytosis (HLH), EBV-positive systemic T-cell lymphoproliferative disease (STLPD) of childhood, and chronic active EBV (CAEBV) infection may develop after primary EBV infection. This study reviewed the clinicopathological spectrum of EBV-associated T- and natural killer (NK)-cell LPD, including STLPD and CAEBV infection, with an analysis of T-cell clonality.

Methods

Clinicopathological features of seven patients with EBV-associated HLH or STLPD and 12 patients with CAEBV infection were reviewed. Immunohistochemical staining and a T-cell receptor (TCR) gene rearrangement study were performed.

Results

STLPD and EBV-positive HLH showed significantly overlapping clinicopathological findings. One patient with STLPD and one patient with EBV-positive HLH demonstrated moderate to severe atypia of the infiltrating lymphocytes, whereas the remaining patients lacked significant atypia. Twelve patients had CAEBV infection, four of whom suffered mosquito-bite hypersensitivity, five showed NK lymphocytosis, and one suffered hydroa vacciniforme. Infiltrating lymphocytes were predominantly small and devoid of atypia. Hemophagocytic histiocytosis was found in seven of 11 patients. Monoclonality was detected in three (50%) of the six patients with successful TCR gene analysis.

Conclusions

EBV-positive HLH and STLPD share similar clinicopathological findings and may constitute a continuous spectrum of acute EBV-associated T- or NK-cell proliferative disorders. The distinction of EBV-positive T-cell LPD from EBV-positive HLH may be difficult during routine diagnoses because of the technical limitations of clonality assessment.

Abstract PDF

The patient was a 52-year-old female with swelling in both lower legs and peripheral blood eosinophilia. Biopsy specimen revealed the heavy infiltration of eosinophils with sparse small lymphocytes showing mild atypia. The diagnosis was Kimura disease. The symptoms including eosinophilia were relieved by steroid treatment. At 17 months from initial biopsy, the patient developed swelling of the buttock. At 25 months, fever and dyspnea with multiple lung nodules developed. Wedge resection revealed multiple aggregates of CD3(+), CD56(+), Epstein-Barr virus(+) large atypical lymphocytes with necrosis. The patient was finally diagnosed with extranodal NK/T cell lymphoma (NKTL). Epstein-Barr virus in situ hybridization retrospectively performed on the previous biopsies demonstrated Epstein-Barr virus infection in small CD3(+) lymphocytes. The patient expired after 26 months despite chemotherapy. Blood eosinophilia correlated well with disease activity during the clinical course. This case shows not only unusual histologic features, which hampered the correct diagnosis, but also a unique clinical manifestation of NKTL.

Abstract PDF

We report an extraordinary case of diffuse large B-cell lymphoma arising in a cystic necrotic mass in a 35-year-old man who presented with a soft tissue mass at the site of previous surgery. A benign mass was surgically removed 17 years ago, after which a cystic lesion gradually developed at the same site. The resected mass appeared as a thick-walled cyst filled with brown necrotic and hemorrhagic material. On microscopic examination, the cyst wall was primarily necrotic tissue with some aggregates of large atypical lymphoid cells. These atypical cells were diffusely positive for CD20 and showed a high proliferation index, Epstein-Barr virus positivity, and clonal rearrangement of the immunoglobulin gene. His present condition was diagnosed as Epstein-Barr virus-associated diffuse large B-cell lymphoma arising from chronic inflammation. It is important to be aware of the clinical manifestations and histological features of this rare disease in light of diagnosis and treatment.

Abstract PDF: Giardiasis is one of the most common causes of infectious diarrhea and it has a worldwide distribution. Although it is a relatively common disorder, histologically confirmed Giardiasis is a rare occurrence and there have been no previous reports in Korea. A 34-year-old man presented with a 2-year history of epigastric discomfort and left flank pain. On stool examination, many cystic forms of Giardia lamblia were noted. In biopsy specimens of the small intestine, there was moderate chronic inflammatory cell infiltration and several trophozoites of Giardia were observed in the intervillous space and luminal surface. The trophozoites were pear shaped symmetrical organisms with two nuclei, and measured 9~10 micrometer in length.

Abstract PDF: A patient with actinomyces infection of the submandibular soft tissue was diagnosed by fine needle aspiration cytology (FNAC). A 38-year-old woman presented with a right submandibular mass which slowly grew in size over one month. Clinically and radiologically, the lesion was considered as tuberculous lymphadenitis or cellulitis. The polymerase chain reaction for tuberculosis was done by aspirated specimen but the result was negative. The smears of aspiration cytology showed characteristic colonies(sulfur granules) of actinomyces in inflammatory background. After antibiotic therapy for eight months, the patient has been well, showing no detectable mass. This patient was simply and rapidly diagnosed by FNAC and can avoid unnecessary surgical biopsy.
