We present a rare case of malignant lymphoma developing from the wall of chronic empyema thoracis. A 54-year old man with a 35 year history of tuberculosis empyema was admitted due to right chest pain and general weakness for 2 months. Under the impression of chronic empyema thoracis with destroyed right lung and tumor on posterior costophrenic sulcus, pleuropneumonectomy including tumor was performed as a single procedure through a right thoracotomy. The tumor arose from the thickened pleura, and it was histologically and immunologically diffuse large cell[non-cleaved] B-cell non-Hodgkin`s lymphoma [NHL]

Background: The most common type of ocular lymphoma is non-Hodgkin lymphoma (NHL), categorized into two groups: indolent (slow growing) and aggressive (rapid growing). Differentiating benign reactive lymphoid hyperplasia (RLH) from malignant ocular adnexal lymphoma (OAL) is challenging. Histopathology, immunohistochemistry (IHC) and flow cytometry have been used as diagnostic tools in such cases. Materials and Methods: In this retrospective case series, from 2002 to 2013 at Farabi Eye Center, 110 patients with ocular lymphoproliferative disease were enrolled. Prevalence, anatomical locations, mean age at diagnosis and the final diagnosis of the disease with IHC were assessed. Comparison between previous pathologic diagnoses and results of IHC was made. Immunoglobulin light chains and B-cell and T-cell markers and other immuno-phenotyping markers including CD20, CD3, CD5, CD23, CD10, CYCLIND1 and BCL2 were evaluated to determine the most accurate diagnosis. The lymphomas were categorized based on revised European-American lymphoma (REAL) classification. Results: Mean age ${\pm}$ SD (years) of the patients was $55.6{\pm}19.3$ and 61% were male. Patients with follicular lymphoma, large B-cell lymphoma or chronic lymphocytic leukemia/small cell lymphoma (CLL/SLL) tended to be older. Nine patients with previous diagnoses of low grade B-cell lymphoma were re-evaluated by IHC and the new diagnoses were as follows: extranodal marginal zone lymphoma(EMZL) (n=1), SLL(n=1), mantle cell lymphoma (MCL) (n=3), reactive lymphoid hyperplasia RLH (n=2). Two cases were excluded due to poor blocks. Flow cytometry reports in these seven patients revealed SLL with positive CD5 and CD23, MCLwith positive CD5 and CyclinD1 and negative CD23, EMZL with negative CD5,CD23 and CD10. One RLH patient was negative for Kappa/Lambda and positive for CD3 and CD20 and the other was positive for all of the light chains, CD3 and CD20. Orbit (49.1%), conjunctiva (16.1%) and lacrimal glands (16.1%) were the most common sites of involvement. Conclusions: Accurate pathological classification of lesions is crucial to determine proper therapeutic approaches. This can be achieved through precise histologic and IHC analyses by expert pathologists.

기관지 연관 림프조직(BALT) 림프종은 폐에서 드물게 발생하는 low grade B-cell 림프종으로서, 대부분 증상이 없고 예후가 좋으며 centrocyte-like cell과 lymphoepithelial lesion이 특징적으로 관찰되어 타 장기의 림프종과는 구별되는 독특한 질병단위를 이루고 있다. 최근 면역조직화학 기법과 분자유전학 기법을 이용하여 단일클론성을 증명함으로써 BALT 림프종의 진단에 많은 도움을 받게 되었다. 저자 등은 폐생검 후 면역조직화학염색과 PCR 등의 방법으로 확진된 BALT 림프종 3예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

다발성 원발성 악성 종양은 한 환자에서 2개 이상의 원발성 악성 종양이 각각 독립적으로 발생하는 경우를 말한다. 저자들은 78세 남자 환자에서 동시에 발생한 유방의 점액성 선암과 유방외 림프종의 증례를 경험하여 보고하고자 한다. 환자는 2개의 만져지는 덩이를 주소로 내원하여 외과적 생검을 통해 좌측 유방의 점액성 선암과 우측 서혜부의 미만성 거대 B세포 림프종을 확진하였다. 이후 수술 전 시행한 PET/CT에서 좌측 혀편도의 우연종이 발견되었고, 절제 생검을 통해 미만성 거대 B세포 림프종을 확진하였다. 유방암 환자에서 불특정한 림프절 비대가 발견되는 경우 전이성 병변으로 간주되기 쉬우나, 이 증례의 환자와 같이 고령의 환자군에서는 림프종을 감별 진단으로 함께 고려함으로써 오진 및 치료 지연을 방지할 수 있을 것이다.

Background: Primary non-Hodgkin's lymphoma of the lung is a rare entity. It is represented commonly as marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) type. Although there have been a few reviews of this lymphoma, clinical features, radiologic findings, management and prognosis have not been well defined. Methods: We reviewed the medical records of 24 patients with primary pulmonary lymphoma between January 1995 and September 2008; all diagnoses had been confirmed based on pathology. Results: The median follow-up time was 42.3 months (range, 0.1~131.2 months). Five (20.8%) patients were asymptomatic, 17 (70.8%) patients had pulmonary symptoms, and the remaining 2 (8.3%) patients presented with constitutional symptoms. There were 16 (66.7%) patients with MALT lymphoma, 4 (16.7%) patients with diffuse large B-cell lymphoma and 4 (16.7%) patients with lymphoma that had not received a WHO classification. Radiologic findings of primary pulmonary lymphoma were diverse and multiple nodule or consolidation was the most common finding regardless of pathologic lymphoma type. PET scan was carried out in 13 (54.2%) patients and all lesions showed notable FDG uptake. MALT lymphoma showed a trend of better prognosis (3-year survival, 78.8% vs. 70.0%; 5-year survival, 78.8% vs. 52.5%; p=0.310) than non-MALT lymphoma. Conclusion: Primary non-Hodgkin's lymphoma of the lung occurs with nonspecific clinical features and radiologic findings. MALT lymphoma is the most common pathologic type of primary pulmonary lymphoma. This entity of lymphoma appears to have a good prognosis and in this study, there was a trend of better outcome than non-MALT lymphoma.

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.

원발성 폐 림프종은 매우 드문 질환으로서 대부분이 BALT기원의 저등급 B-세포 림프종으로 알려져 있다. 국내에서는 원발성 폐 림프종에 대한 연구가 미비하여 보고예가 많지는 않으나 대부분이 T-세포형 림프종이었다. 임상적인 측면에서, T-세포 림프종이 진단당시 진행된 형태로 발견되어 예후가 극히 불량한 것과는 대조적으로 저등급 B-세포 림프종은 비교적 예후가 좋은 것으로 보고되어 있다. 저자 등은 진단후 1년간의 추적 관찰기간 동안 무통성의 만성적인 임상경과를 보이는 비교적 예후가 좋은 저등급 B-세포 원발생 폐 림프종 1 예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Angioimmunoblastic T-cell lymphoma (AITL) is a rare subtype of malignant lymphoma (ML), accounting for only 1 to 2% of all non-Hodgkin's lymphoma (NHL). Although ML of the parotid gland is rare, the majority are B-cell types. The AITL occurring synchronously in the parotid gland and lateral neck has not been reported earlier. It is classified as a high-grade malignancy with aggressive clinical features, and the prognosis is worse than any other type of NHL. We recently encountered a 72-year-old man with multiple mass on the ipsilateral parotid tail and lateral neck, and he was finally diagnosed as AITL. We report the unique and rare disease entity with a brief literature review.
