  • Objective : The aim of this case report is to drive further studies evaluating the effectiveness of Korean oriental medicine on extranodal marginal zone B cells of MALT (mucosa-associated lymphoid tissue) type lymphoma. Methods : This case report is about a patient who was diagnosed with extranodal marginal zone B cell of MALT type lymphoma, who refused chemotherapy and preferred to be treated with Korean oriental medicine. Neck, chest abdomen & pelvis with enhanced computed tomography (CT) and positron emission tomography computed tomography (PET-CT) were performed to evaluate the anticancer effect of Hangam-dan (HAD). Results : The patient diagnosed with MALT showed partial response after receiving 17 months of Korean oriental medical treatment. Neck, chest, abdomen & pelvic CT and PET-CT show decrease in size. Conclusion : This case report shows a possibility that Korean oriental treatment could offer potential benefits for patients with extranodal marginal zone B cell of MALT type lymphoma.

  • Out of all oral malignant tumor, malignant lymphoma occurs in only 3.5%. Especially, most of the primary malignant lymphomas, which occur in the head & neck region are high-grade diffuse large B-cell lymphoma and mucosa-associated lymphoid tissue (MALT) marginal zone B-cell lymphoma is very rare. In the head & neck region, malignant lymphoma is reported to occur in the thyroid, salivary gland, trachea, larynx, orbital lobe and the Waldeyer's ring. Among the Waldeyer's ring, palatal tonsil is reported to be the most common region, but, only 1 case report was published in Korea. Until now, there were no case reports of MALT lymphoma that occurred in the tongue. The purpose of this case report is to report and discuss on a case of MALT lymphoma of the tongue.

  • 아밀로이드증과 비호지킨림프종과의 연관관계는 이전의 연구들에서 보고된 바 있다. 림프종과 아밀로이드증과의 연관관계는 두 개의 구분되는 범주로 나뉘는데 림프종 연관 전신성 아밀로이드증과 종괴 주위 아밀로이드증이다. 저자들은 두경부 MALT 림프종 환자에서 발생한 국소적 종괴 주위 아밀로이드증의 드문 증례를 보고하고자 한다. 전산화단층촬영에서 병변은 연조직음영을 보이는 무정형석회화를 동반한 불규칙한 모양의 종괴였으며, 조영증강 시 불균일한 조영증강을 보였다. 자기공명영상에서는 종괴가 T1 강조영상과 T2 강조영상에서 모두 불균일한 낮은 신호 강도를 보였다. 종괴는 강한 조영증강을 보였으며, 내부에는 여러 개의 조영증강되지 않는 부분들을 포함하고 있었다. 림프종 환자에서 치료 전 영상검사에서 발견된 석회화들은 종괴 주위 아밀로이드증과 같은 동반된 다른 이차성 병변을 시사하는 소견이 될 수 있을 것이다.

  • Purpose: To retrospectively analyze dosimetric parameters of volumetric-modulated arc therapy (VMAT) and three-dimensional conformal radiotherapy (3D-CRT) delivered to extranodal marginal zone B-cell lymphomas of mucosa-associated lymphoid tissue in the stomach (gastric MALT lymphoma) to find out advantages of VMAT and conditions for definite benefits of VMAT. Materials and Methods: Fifty patients with stage I-II gastric MALT lymphoma received VMAT (n = 14) or 3D-CRT (n = 36) between December 2005 and April 2018. Twenty-seven patients were categorized according to whether the planning target volume (PTV) overlaps kidney(s). Dosimetric parameters were analyzed by dose-volume histogram. Results: Radiation dose to the liver was definitely lower with VMAT in terms of mean dose (p = 0.026) and V15 (p = 0.008). The V15 of the left kidney was lower with VMAT (p = 0.065). For those with PTV overlapping kidney(s), the left kidney V15 was significantly lower with VMAT. Furthermore, the closer the distance between the PTV and kidneys, the less the left kidney V15 with VMAT (p = 0.037). Delineation of kidney(s) by integrating all respiratory phases had no additional benefit. Conclusions: VMAT significantly increased monitor units, reduced treatment time and radiation dose to the liver and kidneys. The benefit of VMAT was definite in reducing the left kidney V15, especially in geometrically challenging conditions of overlap or close separation between PTV and kidney(s).

  • Purpose: Primary malignant lymphomas of the salivary glands are uncommon. The parotid gland was most frequently involved, followed by the submandibular gland, minor salivary gland and sublingual gland. The most common subtype is mucosa - associated lymphoid tissue(MALT) lymphoma. We experienced a case of salivary MALT lymphoma involving parotid gland duct, so report a case with a review of the literature. Methods: A 65 year old female presented with a palpable mass on the left side of her cheek. There was no clinical or laboratory evidence of pre - existing autoimmune disease. Preoperative facial and neck CT with contrast showed $2.1{\times}1.7cm$ sized, ill defined, homogeneous low density mass near left masseter muscle, and no evidence of other enlarged lymph nodes. Results: At operation, a yellowish oval shaped mass was found slightly adhered to middle portion of the parotid gland duct, meaduring $2{\times}1.5{\times}0.7cm$. Microscopic finding showed that centrocyte - like cells, monocyte B cells and plasma cells were diffusely infiltrated. Immunophenotyping was preformed on fixed section. The majority of the small cells were immunoreactive for the B cell marker CD20. Based on the typical histological findings supported by immunostaining, the mass was defined as MALT lymphoma. Conclusion: We report that very rare case of MALT lymphoma involving parotid gland duct in 65 year old female patient was experienced with clinical characteristics, histologic features and references.

  • Background Primary ocular adnexal extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (POML) is the most common subtype of lymphoma involving the eyes in Thailand. We sought to assess the characteristics and treatment outcomes of patients with POML in Thailand. Methods We retrospectively reviewed patient data and included patients diagnosed with POML between January 2004 and December 2016 at Chiang Mai University Hospital and King Chulalongkorn Memorial Hospital, Thailand. We collected and analyzed patients' clinical characteristics and treatment outcomes. Results Among 146 patients with lymphoma involving the eyes, 121 (82%) were diagnosed with POML. Sixty-four (52.9%) were women with median age 58 (range, 22-86) years. The most common presenting symptom was orbital mass (71.1%). Common sites of origin were the orbit (46.3%) and lacrimal gland (34.7%). At presentation, 22.3% of patients had bilateral eye involvement. About half of patients had stage I disease (N=59, 56.2%) and 20% had stage IV. Most patients (73.3%) had a low-risk International Prognostic Index. Radiotherapy was the main treatment for patients with limited-stage disease (66.7% in stage I and 56.5% in stage II). The overall response rate was 100% with complete response rates 80%, 77.3%, and 64.7% for stages I, II, and IV, respectively. Five-year progression-free survival (PFS) and overall survival were 66.1% and 94.0%, respectively. For patients with limited-stage disease, radiotherapy significantly improved PFS compared with treatment not involving radiotherapy (5-year PFS 89.9% vs. 37.3%, P=0.01). Conclusion We revealed that POML has good response to treatment, especially radiotherapy, with excellent long-term outcome.

  • We report a case of dural marginal zone lymphoma which showed the usual radiological findings resembling meningioma. A 59-year-old woman presented with headache. Initial computed tomography and magnetic resonance images showed a frontal convexity meningioma. The patient underwent a craniotomy and subtotal (simpson grade II) resection of tumor was done. Pathological examination confirmed an extranodal marginal zone B-cell lymphoma of Mucosa-Associated Lymphoid Tissue (MALT). The lesion was composed of a lymphoid mass with irregularly shaped follicles surrounded by many monomorphic small lymphocytes and a stained marginal zone for B-cell markers CD20 and CD29a. The natural history of primary CNS lymphoma and MALT type lymphoma are different. B-cell MALT lymphoma can mimic meningioma in its radiological features. Accordingly, MALT lymphoma of the CNS must be considered in the differential diagnosis of meningioma.
