악성 림프종은 흉부 CT에서 결절, 종양, 폐 경화, 간유리음영 등 다양한 폐질환으로 나타날 수 있으며 이러한 폐 병변은 다른 질환의 양상과 유사하여 진단에 어려움을 줄 수 있다. 본 증례는 호흡곤란과 발열을 주 증상으로 하는 67세 남성 환자로 해당 환자의 흉부 CT상 크기가 작은 다발성 결절이 양측에 미만성으로 나타나 혈행성 전이, 좁쌀 결핵 또는 진균 감염을 의심해 볼 수 있었다. 그러나 추가적으로 시행한 혈액 검사, 영상 검사 및 조직 생검 결과 폐를 침범한 미만성 큰 B세포 림프종이 진단되었다. 저자들은 폐의 좁쌀 결절로 발현한 매우 드문 림프종을 보고한다. 환자의 적절한 진단을 위해서는 환자의 병력, 신체 진찰, 혈액 검사 및 영상 소견의 포괄적인 평가가 필요하다.

Pyothorax-associated lymphoma is a relatively rare type of lymphoma that occurs in patients who have long histories of tuberculous pleuritis or induced pneumothorax. It is a type of non-Hodgkin's lymphoma of mainly the B-cell phenotype and is strongly associated with Epstein-Barr virus infection. A majority of these cases have been reported in Japan, although some cases have occurred in Western countries. Here, we describe a case of pyothorax-associated lymphoma in a patient with a 30-year history of chronic tuberculous empyema. The patient underwent decortication under the impression of chronic empyema with fistula. The histopathologic diagnosis was a diffuse large B-cell lymphoma associated chronic inflammation.

Mucosa-associated lymphoid tissue (MALT) lymphoma is one of the most common lymphomas and accounts for about 7% of all newly diagnosed non-Hodgkin's lymphoma (NHL). The clinical course of MALT lymphoma is relatively indolent and, in the majority of cases (50%), the lymphoma arises within the stomach. Primary central nervous system lymphoma (PCNSL), an uncommon variant of extranodal NHL, can affect any part of the neuraxis, including the eyes, brain, leptomeninges, or spinal cord. Herein, we present a rare case of PCNSL, which occurred one year after radiochemotherapy of gastric MALT lymphoma. A 62-year-old man presented with a 3-day history of left facial palsy. One year ago, he underwent antibiotic eradication therapy of Helicobacter pylori, local stomach fractional radiotherapy, and chemotherapy for gastric MALT lymphoma. Magnetic resonance imaging revealed a strong enhancing solid mass in the right frontal lobe. The tumor was completely removed, and the histological diagnosis of PCNSL developing from diffuse large B-cell lymphoma was made. Although elucidating the correlation between the first gastric MALT lymphoma and the second PCNSL seemed difficult, we have postulated and discussed some possible pathogeneses, together with a review of literature.

Objective: We aimed to identify key genes, pathways and function modules in the development of diffuse large B-cell lymphoma (DLBCL) with microarray data and interaction network analysis. Methods: Microarray data sets for 7 DLBCL samples and 7 normal controls was downloaded from the Gene Expression Omnibus (GEO) database and differentially expressed genes (DEGs) were identified with Student's t-test. KEGG functional enrichment analysis was performed to uncover their biological functions. Three global networks were established for immune system, signaling molecules and interactions and cancer genes. The DEGs were compared with the networks to observe their distributions and determine important key genes, pathways and modules. Results: A total of 945 DEGs were obtained, 272 up-regulated and 673 down-regulated. KEGG analysis revealed that two groups of pathways were significantly enriched: immune function and signaling molecules and interactions. Following interaction network analysis further confirmed the association of DEGs in immune system, signaling molecules and interactions and cancer genes. Conclusions: Our study could systemically characterize gene expression changes in DLBCL with microarray technology. A range of key genes, pathways and function modules were revealed. Utility in diagnosis and treatment may be expected with further focused research.

This study presents a case of diffuse large B cell lymphoma (DLBCL) in a 58-year-old man showing unusual manifestations mimicking chronic osteomyelitis. In this case review, we describe the imaging findings of DLBCL which mimics chronic osteomyelitis and review existing reports regarding the differential diagnosis of bone involvement of lymphoma and osteomyelitis through imaging and laboratory findings and diffusion-weighted magnetic resonance imaging (DWI) such as the advanced MRI sequence.

Neurolymphomatosis (NL) is defined as the involvement of the peripheral nervous system in lymphocytic invasion. It is a very rare form of lymphoma that may occur as an initial presentation or recurrence. It affects various peripheral nervous structures and can therefore mimic disc-related nerve root pathology or compressive mononeuropathy. NL often occurs in malignant B-cell non-Hodgkin lymphomas. Notwithstanding its aggressiveness or intractability, NL should be discriminated from other neurologic complications of lymphoma. Herein, we present a case of primary NL as the initial presentation of diffuse large B-cell lymphoma (DLBCL) of the sciatic nerve. The patient presented with weakness and pain in his left leg but had no obvious lesion explaining the neurologic deficit on initial lumbosacral and knee magnetic resonance imaging (MRI). NL of the left sciatic nerve at the greater sciatic foramen was diagnosed based on subsequent hip MRI, electrodiagnostic test, positron emission tomography/computed tomography, and nerve biopsy findings. Leg weakness slightly improved after chemotherapy and radiotherapy. We report a case wherein NL, a rare cause of leg weakness, manifested as the initial presentation of primary DLBCL involving the sciatic nerve at the greater sciatic foramen.

금속성 임플란트 삽입과 관련된 만성 염증 상태는 미만성 거대 B세포 림프종 발생의 위험 요소이다. 금속 이온은 림프종의 발병에 중요한 역할을 하는 것으로 알려져 있다. 저자들은 15개월 동안 근위 경골에 금속성 임플란트가 삽입된 환자에서 발생한 드문 미만성 거대 B세포 림프종 증례를 보고하고자 한다. 초음파 및 자기공명영상을 촬영하였으며 현저한 골 파괴 없이 불균형적으로 큰 골외 연조직 종괴와 골수 침범이 관찰되었다. 금속성 임플란트 삽입과 관련된 여러 합병증들이 있으며 오진하면 잘못된 치료로 이어질 수 있다. 따라서 금속성 임플란트로 인한 만성 염증 상태와 연관된 림프종과 임플란트 주위에 발생할 수 있는 다른 양성 병변 및 악성 연조직 종괴를 감별하는 것은 어렵지만 매우 중요하다.

Primary malignant lymphoma of the thyroid gland is uncommon malignancies. Its fine needle aspiration cytology (FNAC) findings are rarely described in the literature. This article highlights the FNAC diagnosis of primary malignant lymphoma of the thyroid gland. A 70-year-old female presented with a rapidly enlarging thyroid mass of five months' duration. FNAC smears showed low cellularity consisting of predominantly atypical enlarged lymphoid cells admixed with a few small lymphocytes, plasma cells, and oncocytic cells. Some disrupted lymphoid cells were also present. The tumor cells infiltrated into the thyroid follicular epithelium forming lymphoepithelial lesion, The cytologic appearance showed a diffuse mixture of cell types with only a few small, mature lymphocytes and many enlaraed lymphoid cells. The enlarged lymphoid cells were atypical and pleomorphic with nuclear clefting and irregularities. Grossly, the left lobe of the thyroid was nearly replaced by a diffuse firm to soft solid mass with smooth tan fish-flesh homogeneous cut surface. Histological diagnosis was diffuse large B-cell lymphoma with areas of marginal zone B-cell lymphoma of MALT type.

간문맥 종양혈전이 있으면서 간 실질에 이상 소견이 없는 것은 매우 드문 일이다. 간에서 종양 혈전이 있는 경우 간세포암이 가장 발생률이 높으며 림프종은 감별질환으로 잘 생각되지 않는다. 림프종의 종양혈전이 간문맥을 침범한 것은 이제까지 총 네 가지 경우에서만 보고되어 있고, 모든 경우에서 종양이 혈관으로 직접 전파되거나 또는 그 외의 림프종을 시사하는 다른 병변들이 있었다. 혈관 내 대세포 림프종이 간문맥을 함께 침범한 경우, 본 케이스와 영상학적으로 비슷하게 보일 수 있으나 본 증례 보고는 혈관 내 대세포 림프종이 아니므로 제외하여 생각하였다. 미만성 거대 B세포 림프종이 간문맥에서만 발견된 무증상의 면역력이 정상인 67세 여자 환자에 대한 증례를 소개한다. 이전에 발표된 증례에서 이와 비슷한 경우는 보고된 바가 없다.
