Primary cutaneous plasmacytoma (PCP) is a very rare cutaneous B-cell lymphoma that arises primarily in the skin. A few cases of PCP have been reported previously. PCPs are histologically similar to cutaneous B-cell lymphoma and are characterized by dense monoclonal plasma cell infiltration in the dermis. PCP can manifest as a single lesion or as multiple lesions. A solitary lesion can be treated with surgical excision or local radiotherapy. We describe the case of a patient with primary cutaneous plasmacytoma that was treated with intralesional steroid injections.

Primary extranodal non-Hodgkin's lymphomas comprise approximately 10% of all non-Hodgkin's lymphomas. However, primary tracheal non-Hodgkin's lymphoma is extremely rare, being mainly mucosa-associated lymphoid tissue lymphoma. A 65-year-old female has dry cough for one year. She was diagnosed as diffuse large B-cell lymphoma via bronchoscopic-guided biopsy. She was treated with four cycles of the R-CHOP regimen and adjuvant radiotherapy. After completion of the combined treatment, the treatment response was complete remission, and the disease free survival was 26 months.

PURPOSE: To assess the clinical outcomes of radiotherapy (RT) using two-dimensional (2D) and three-dimensional conformal RT (3D-CRT) for patients with gastric mucosa-associated lymphoid tissue (MALT) lymphoma to evaluate the effectiveness of involved field RT with moderate-dose and to evaluate the benefit of 3D-CRT comparing with 2D-RT. MATERIALS AND METHODS: Between July 2003 and March 2015, 33 patients with stage IE and IIE gastric MALT lymphoma received RT were analyzed. Of 33 patients, 17 patients (51.5%) were Helicobacter pylori (HP) negative and 16 patients (48.5%) were HP positive but refractory to HP eradication (HPE). The 2D-RT (n = 14) and 3D-CRT (n = 19) were performed and total dose was 30.6 Gy/17 fractions. Of 11 patients who RT planning data were available, dose-volumetric parameters between 2D-RT and 3D-CRT plans was compared. RESULTS: All patients reached complete remission (CR) eventually and median time to CR was 3 months (range, 1 to 15 months). No local relapse occurred and one patient died with second primary malignancy. Tumor response, survival, and toxicity were not significantly different between 2D-RT and 3D-CRT (p > 0.05, each). In analysis for dose-volumetric parameters, D(max) and CI for PTV were significantly lower in 3D-CRT plans than 2D-RT plans (p < 0.05, each) and D(mean) and V₁₅ for right kidney and D(mean) for left kidney were significantly lower in 3D-CRT than 2D-RT (p < 0.05, each). CONCLUSION: Our data suggested that involved field RT with moderate-dose for gastric MALT lymphoma could be promising and 3D-CRT could be considered to improve the target coverage and reduce radiation dose to the both kidneys.

Primary cutaneous diffuse large B-cell lymphoma is characterized by a diffuse infiltration of atypical large centroblasts and immunoblasts through the dermis without extracutaneous involvement. We report a case of primary cutaneous diffuse large B-cell lymphoma in a 71-year-old female, who presented with a solitary erythematous nodule on the inner thigh. Physical examination and staging work-up revealed no other extracutaneous or systemic involvement. After radiotherapy, the skin lesion had almost cleared, and no evidence of extracutaneous involvement was observed for 4 months.

Approximately 90% of gastric mucosa-associated lymphoid tissue (MALT) lymphomas are associated with Helicobacter pylori infection and 10% of gastric MALT lymphomas occur independent of H. pylori infection. The gene translocation t(11;18)(q21;q21) is frequently observed in cases presenting with H. pylori-negative gastric MALT lymphomas. H. pylori-negative gastric MALT lymphomas do not differ from H. pylori-positive gastric MALT lymphomas in terms of clinical features and endoscopic findings and show similar prognosis. H. pylori eradication therapy could be considered as first-line treatment for gastric MALT lymphomas regardless of their H. pylori infection status. In cases with H. pylori-negative gastric MALT lymphomas, the rate of response to eradication therapy varies from 0 to 83%. If gastric MALT lymphoma persists for more than a year, secondary treatment with radiotherapy, chemotherapy, and/or surgery should be considered. Of note, the comparative outcome is excellent.

The concurrence of lymphoma with pregnancy has been rare but is most commonly associated with an aggressive histology and disseminated disease. Thus, extensive staging is required, and either local radiotherapy or systemic chemotherapy is indicated as soon as possible. We have experienced a case of diffuse, large B-cell lymphoma, stage III2 diagnosed at 31 weeks of gestational age. During pregnancy period, CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone) chemotherapy was performed and complete remission of disease was attained. The infant was successfully delivered at 34 weeks in gestation without any gross anomaly or combined disease. We report a case of diffuse large B-cell lymphoma successfully treated with combination chemotherapy during pregnancy and a brief review of the literatures.

PURPOSE: Lymphoproliferative lesions of the ocular adnexa were analyzed to examine the final outcome, recurrence and extraorbital spread. METHODS: The biopsies and clinical follow up data for 55 patients (68 eyes) with ocular adnexal lymphoproliferative lesions were reviewed retrospectively and analyzed according to the WHO classification. RESULTS: The ocular-adnexal lymphoproliferative lesions were located as follows: orbit in 49 eyes, conjunctiva in 18 eyes, eyelid in 1 eye. The three main subtypes of lymphoma according to the WHO classification were extranodal marginal zone B-cell lymphoma of mucosa- associated lymphoid tissue (MALT-lymphoma) (62 eyes), diffuse large B-cell lymphoma (2 eyes), and benign lymphoid hyperplasia (4 eyes). Remission was achieved at 60eyes. Recurrence was occurred in 7eyes (orbit: 4, conjunctiva: 3) of MALT-lymphoma cases. Location of lymphoma at presentation was not a predictor for recurrence (conjunctiva 16.7%, orbit 8.2%; p>0.05), but bilaterality at presentation was predictive values for recurrence by a statistically significant difference(bilateral 23.1%, unilateral 4.8%; p=0.045). CONCLUSIONS: Most common ocular adnexal lymphoma in Korea was MALT- lymphoma (91.2%). Bilaterality has a predictive values on recurrence, and extraorbital spread was found only in orbital MALT-lymphoma. It is suggested that orbital MALT- lymphoma should be treated with excisional biopsy and subsequent low dose radiotherapy and followed up indefinity.

PURPOSE: The aim of this study was to evaluate the clinical features, histologic classification and treatment outcomes of patients with malignant lymphoma of the eye. METHODS: The participants included 22 patients with malignant lymphoma of the orbit and ocular adnexa treated at our hospital between May 1994 and September 2001. The authors retrospectively analyzed the sex, age, location of mass, histopathologic type, stage and results of the treatment. RESULTS: Of the 22 patients, 14 cases were male and 8 were female. The age ranged from 26 to 68 years (mean age 43 years). The most common presenting complaint was slowly growing mass of the eye. Histopathologic studies revealed extranodal marginal zone B-cell lymphoma, MALT type in 20 cases (91%). The stages of lymphomas were included I AE in 14 cases (63%), II AE in 3 cases (14%), III AE in 3 cases (14%) and IV A in 2 cases (9%). Patients received radiotherapy and/or chemotherapy. Twenty out of 22 cases (91%) achieved a complete remission. During the mean follow-up of 26 months, two patients died of progression of the disease; one patient had extranodal marginal zone B-cell lymphoma, MALT type of stage III AE and the other patient had diffuse large cell lymphoma of stage II AE. CONCLUSIONS: Radiotherapy can produce durable remission in the majority of the patients with localized primary orbital lymphoma. Chemotherapy should be performed for the patients with highly malignant lymphomas or lymphomas with systemic manifestations.

BACKGROUND: Primary lymphoma of the breast is rare disease, accounting for 1.7% to 2.2% of extranodal lymphoma and 0.38% to 0.7% of non-Hodgkin's lymphoma. The aim of this study was to evaluate the clinicopathological features and treatment outcome of patients with primary breast lymphoma (PBL). METHODS: We conducted retrospective review of cases of non-Hodgkin's lymphoma diagnosed at Korea Cancer Center Hospital between 1989 and 2002. Nine of the 1050 cases fulfilled the criteria for PBL. RESULTS: All patients were women (median age, 45 years) and they usually had breast masses that had recently become enlarged. Six cases involved the breast alone (stage IE), whereas three cases also involved the ipsilateral lymph nodes (stage IIE). Histopathologic studies revealed diffuse large B cell in 7 cases, marginal zone B cell lymphoma in 1 case, small lymphocytic lymphoma in 1 case. Immunohistochemical analysis revealed B-cell phenotype in all cases. Modified radical mastectomy and chemotherapy was done in 4 cases, modified radical mastectomy and chemoradiotherapy was done in 1 case, chemoradiotherapy was done in 1 case, modified radical mastectomy alone was done in 1 case, chemotherapy alone was done in 1 case, and radiotherapy alone was done in 1 case. All cases achieved a complete remission, but median overall survival was 12 months. CONCLUSION: PBL represented 0.9% of all non-Hodgkin's lymphomas in our institute. The most frequent pathologic type was diffuse large B-cell lymphoma. There was no uniform approach to the treatment of PBL. The patients showed very poor prognosis irrespective of the type of treatment modality.

BACKGROUND: Non-Hodgkin's lymphoma presenting in the eye is a rare disorder. The aim of this study was to evaluate the clinical features, treatment outcome and complications of patients with non-Hodgkin's lymphoma of the eye. METHODS: We designed retrospective, observational case study. The participants included 22 consecutive patients with non-Hodgkin's lymphoma of the orbit and ocular adnexa treated at the Yeungnam University Hospital between 1992 and 2001. RESULTS: There were 16 males (73%) and 6 females (27%). The median age at ocular presentation was 47. The most common presenting complaint was slowly growing mass at the eye. Histopathologic studies revealed extranodal marginal zone B-cell lymphoma, MALT type in 19 cases (86%), B-cell small lymphocytic lymphoma in one case, diffuse large B-cell lymphoma in one case, and lymphoplasmacytoid lymphoma/immunocytoma in one case. The stages of lymphomas were IA(E) in 17 cases (82%), IIA(E) in 2 cases (9%), IIIA(E) in 2 cases (9%). Radiotherapy alone was employed in 17 cases, chemoradiotherapy was done in 3 cases, chemotherapy alone was administered in one case. Nineteen out of 21 cases (90%) achieved a complete remission, and 5 year survival rate was approximately 90%. Subgroup analysis of the patients with lymphomas in stage IA(E) revealed that complete response rate was 100% and 5 year survival rate was 100% CONCLUSION: Radiotherapy alone can produce durable remission in the majority of the patients with localized extranodal marginal zone B-cell lymphoma, MALT type. However, combination chemotherapy or chemoradiotherapy should be considered in the patients with aggressive lymphomas or indolent lymphomas with systemic manifestation.
