Secondary prevention via earlier detection would afford the greatest chance for a cure in premalignant lesions. We investigated the exomic profiles of non-malignant and malignant changes in head and neck squamous cell carcinoma (HNSCC) and the genomic blueprint of human papillomavirus (HPV)-driven carcinogenesis in oropharyngeal squamous cell carcinoma (OPSCC). Whole-exome (WES) and whole-genome (WGS) sequencing were performed on peripheral blood and adjacent non-tumor and tumor specimens obtained from eight Korean HNSCC patients from 2013 to 2015. Next-generation sequencing yielded an average coverage of $94.3{\times}$ for WES and $35.3{\times}$ for WGS. In comparative genomic analysis of non-tumor and tumor tissue pairs, we were unable to identify common cancer-associated early mutations and copy number alterations (CNA) except in one pair. Interestingly, in this case, we observed that non-tumor tonsillar crypts adjacent to HPV-positive OPSCC appeared normal under a microscope; however, this tissue also showed weak p16 expression. WGS revealed the infection and integration of high-risk type HPV16 in this tissue as well as in the matched tumor. Furthermore, WES identified shared and tumor-specific genomic alterations for this pair. Clonal analysis enabled us to infer the process by which this transitional crypt epithelium (TrCE) evolved into a tumor; this evolution was accompanied by the subsequent accumulation of genomic alterations, including an ERBB3 mutation and large-scale CNAs, such as 3q27-qter amplification and 9p deletion. We suggest that HPV16-driven OPSCC carcinogenesis is a stepwise evolutionary process that is consistent with a multistep carcinogenesis model. Our results highlight the carcinogenic changes driven by HPV16 infection and provide a basis for the secondary prevention of OPSCC.

Membranous glomerulonephritis can manifest as a paraneoplastic syndrome. The presence of evidence that supports the relationship between malignancy and membranous glomerulonephritis remains unresolved, though. Membranous glomerulonephritis has been commonly reported as associated with solid or hematologic malignancy, such as lung cancer, prostate cancer, and gastro-intestinal cancer, but its concomitant existence with skin cancer is rare. This paper reports a case of membranous glomerulonephritis combined with basal cell carcinoma that was successfully treated with the excision of the basal skin cell carcinoma.

흉막의 종괴는 다양한 양성과 악성 종양이 있고 종양은 아니지만 종양 같은 질환들에 의해 발생한다. 일차 흉막 종양에는 고립섬유종양, 악성중피종, 그리고 원발성 흉막 비호지킨 림프종이 있다. 흉막에 발생하는 가장 흔한 종양은 전이성 질환이며, 림프종, 백혈병, 다발성 골수종 등의 혈액 종양을 가진 환자에서 드물게 나타난다. 흉수는 주로 흉막의 악성 질환과 연관이 있다. 드물지만 흉막 종양이 만성 농흉에서 생길 수 있으며, 그중 가장 흔한 것은 비호지킨 림프종이다(농흉과 연관된 림프종). 종양이 아닌 흉막 종괴로는 다양한 양성 질환에서 보일 수 있으며, 여기에는 결핵, 석면 흉막판, 그리고 흉막 유리체가 포함된다. 이 임상화보에서 저자들은 흉막의 다양한 양성과 악성 종양 및 종양성 질환들에 대한 특징적인 전산화단층촬영 소견에 대해 알아보고자 한다.

배경: 침습성 폐아스페르길루스증은 면역체계가 낮은 환자들에게 흔한 진균감염으로, 특히 백혈병으로 항암제 치료를 받고 있는 환자들에서는 항진균제 치료에 반응이 적은 것으로 알려져 있다. 저자들은 백혈병의 치료 중 합병된 폐아스페르길루스증에 대하여 모두 폐절제술을 시행하였으며, 그의 효과 등을 알아보고자 하였다. 대상 및 방법: 1998년 2월부터 2007년 4월까지 혈액암 질환의 진단과 함께 침습성 폐아스페르길루스증 진단을 받은 환자 14명을 대상으로 후향적인 검토를 하였다. 환자의 의무기록을 통해 혈액암(기저질환)의 종류와 그에 따른 치료, 침습성 폐아스페르길루스증의 진단방법, 수술 전 혈액학적 상태와 처치, 수술방법, 수술 후 합병증과 사망여부, 수술 후 폐아스페르길루스증의 재발현율 및 골수이식 여부 등을 조사하였다. 결과: 침습성 폐아스페르길루스증이 합병된 혈액암 환자 14명에서 모두 폐엽절제술이 시행되었다. 수술 후 1명의 환자에서 기관지흉막루가 발생되었으나, 기타 창상감염, 출혈 등의 위중한 합병증이나 수술 후 사망한 환자는 없었으며, 모두 백혈병치료를 지속할 수 있었다. 결론: 침습성 폐아스페르길루스증은 혈액암에 대한 치료 도중 종종 발생되는 위중한 질환이나, 폐엽절제술은 안전하며 효과적으로 혈액암의 치료를 유지시켜 줄 수 있는 치료법으로 생각한다.

Gelatinous transformation of bone marrow is characterized by hypoplasia of fat cells with focal loss of hematopoietic cells and deposition of extracellular gelatinous substances. It is known to be associated with devastating underlying diseases that starve bone marrow. Here, we present a case of a patient whose magnetic resonance (MR) imaging findings of vertebral column were interpreted as metastasis or hematologic malignancy, however, the final diagnosis revealed a gelatinous transformation of bone marrow. This is the first report of gelatinous transformation of bone marrow without evidence of underlying devastating disease.

뮤코르진균증은 비교적 드문 질환으로 면역이 저하된 환자에게 있어서 치명적인 기회감염을 일으킨다. 감염은 주로 혈액암, 만성 신부전, 당뇨 환자나 장기이식을 받은 환자에게 일어난다. 저자들은 조절되지 않은 당뇨를 동반한 신장이식을 받은 환자에서 발생한 폐뮤코르진균증을 암포테리신과 함께 수술적 절제를 통해 성공적으로 치료하였다.

Allogenic hematopoietic stem cell transplantation is one of the effective therapy for several hematologic malignancies. Transplantation preparative regimen is designed to eradicate the patient's underlying disease and immunosuppress the patient adequately to prevent rejection of donor's hematopoietic stem cells. So, conventional myeloablative preparative regimens with high-dose chemotherapy or radiotherapy are related to high rate of morbidity and mortality. However, It has become clear that the high-dose therapy dose not eradicate the malignancy in some patients, and that the therapeutic benefit of allogenic transplantation is largely related to graft-versus-leukemia/graft-versus-tumor (GVL/GVT) effect. An new approach is to utilize less toxic, nonmyeloablative preparative regimens to achieve engraftment and allow GVL/GVT effects to develop. This strategy reduces the risk of treatment-related mortality and allows transplantation for elderly and those with comorbidities that preclude high-dose chemoradiotherapy.

As a potent antigen presenting cells and a powerful inducer of antigen specific immunity including cytotoxic T cell activity, dendritic cells(DCs) are being considered as a promising anti-tumor therapeutic module. Unlike solid tumors, leukemia is the hematologic malignancy involving immune effector cells. The expected usage of DCs in leukemia is the treatment of minimal residual disease(MRD) after the remission or stem cell transplantation. In this study, syngeneic leukemia cells were inoculated intra-venously into the mouse (WEHI-3 into the Balb/c), and the autologous tumor cell lysate pulsed DCs were injected as a therapeutic module twice in two weeks.

Oxaliplatin is a third-generation platinum compound widely used to treat gastrointestinal malignancy. One of the major side effects of oxaliplatin is thrombocytopenia, the development of which can limit appropriate treatment. We report a 38-year-old man with advanced gastric cancer who developed severe thrombocytopenia after FOLFOX4 (oxaliplatin, leucovorin, and fluorouracil) chemotherapy. The thrombocytopenia was associated with therapy-related myelodysplastic syndrome after cytotoxic chemotherapy and was confirmed by bone marrow biopsy and genetic study. Therefore, physicians should be aware of therapy-related hematologic complications, especially with an oxaliplatin-based chemoregimen, and might consider the bone marrow study in those patients.

대혈관 혈관염은 대동맥과 이것의 주요 분지의 혈관벽에 만성 염증이 생기는 질환으로써 면역 이상반응에 의한 것이다. 혈액암은 이차적인 혈관염의 아주 드문 원인 중 한 가지다. 우리는 일차성 혈관염을 모방한 급성 골수성 백혈병과 연관된 드문 형태의 대혈관 혈관염에 대해서 보고하고자 한다.
