Objective: This study aimed to see how different initial treatment regimens affected the long-term prognosis of patients with extranodal marginal zone mucosa-associated lymphoid tissue lymphoma confining to the ocular adnexal (OAML) . Methods: Between April 2008 and April 2019, 109 patients with initial mucosa-associated lymphoid tissue confining to ocular adnexal were evaluated and followed-up, and the prognosis of various initial treatment regimens were examined. Results: A total of 36 patients underwent complete surgical resection of the lesions, and 73 patients had residual lesions after surgery, of which 37 patients chose watchful waiting, and 36 patients chose treatment. The treatment regimen included local radiotherapy and systemic treatment (chemotherapy, immunochemotherapy, the combination of radiotherapy and chemotherapy, etc.) , and no serious toxic and side effects were observed in patients receiving systemic treatment. The median follow-up time was 61 (10-142) months. The 5-year and 10-year progression-free survival (PFS) of monocular involvement patients were 78.2% and 76.0% . The 5-year and 10-year PFS rates of patients with binocular involvement were 64.4% and 23.5%. There was significant diference in PFS between patients with monocular and binocular involvement (P=0.010) . Patients who received additional treatment had higher PFS than those patients in the watchful waiting group (P=0.046) . The 5-year PFS was 71.4% and 90.1% among patients in the watchful waiting group and those who received additional treatment, whereas the 10-year PFS was 63.5% and 75.1% , respectively. Patients with OAML were still a risk of disease progression after 5 years. Conclusions: Patients with binocular involvement OAML at the start of the disease had a poor prognosis, but treatment could reduce the risk of recurrence/progression. Systemic therapy is one of the first-line treatment options for patients with OAML, who require long-term monitoring.

B-cell lymphoma is the most common malignant lymphoma, and its incidence is increasing year by year. Some types are often indistinguishable from the reactive lesions through morphology combined with immunohistochemistry, so other auxiliary diagnostic methods are urgently needed. Since B-cell lymphoma is caused by malignant transformation of IGH rearranged B cells, the molecular characteristics of rearranged B cells can be used as an important reference for differentiating benign and malignant proliferations of lymphatic tissues. With the development of molecular biology technology, the detection of clonal rearrangement of IGH plays an important role in the diagnosis, efficacy evaluation and prognosis evaluation of lymphoma. This paper focuses on the molecular characteristics and clinical significance of clonal rearrangement of IGH in B-cell lymphoma.

Papillary thyroid carcinoma (PTC) is a common lesion, accounting for 70-80% of all thyroid cancers, whereas mucosa-associated lymphoid tissue (MALT) lymphoma of thyroid gland is rare. A simultaneous occurrence of both malignancies is extremely rare. 57 years old Korean woman diagnosed with Hashimoto's thyroiditis at left lobe of thyroid gland where atypical cells of undetermined significance at right lobe. Later, left lobe was confirmed with malignant lymphoma during series of fine-needle aspiration biopsy. Right lobe was interpreted as malignant lesions, such as papillary thyroid carcinoma based on ultrasonography images and previous biopsy results. Total thyroidectomy was performed. Pathology reported papillary thyroid carcinoma at right lobe and MALT lymphoma at left lobe. There were no post-operative complications and no recurrence yet reported. Since an association between Hashimoto's thyroiditis and development of MALT lymphoma has been reported previously, a history of Hashimoto thyroiditis should be suspected MALT lymphoma.

Primary gastrointestinal lymphoma is the most common type of extranodal non-Hodgkin's lymphoma. Most cases are defined histologically as mucosa-associated lymphoid tissue (MALT) lymphoma, while low-grade MALT lymphoma affecting the stomach and duodenum simultaneously is rare. In this case report, we describe the case of a 55-year-old female who presented to the gastroenterology clinic at our hospital for management of gastric adenoma and duodenal polyp by endoscopic mucosal resection and polypectomy. The pathology report noted MALT lymphoma with submucosal tubulovillous adenoma and hyperplastic polyps in the stomach and duodenum. She underwent eradication of Helicobacter pylori using proton pump inhibitor-based triple therapy.

Lymphoepithelial cysts of the pancreas are a type of true cyst that can mimic pseudocysts and cystic neoplasms. They are very rare, non-malignant lesions that are unilocular or multilocular cystic lesions lined predominantly by mature squamous epithelium and surrounded by non-neoplastic lymphoid elements. We, herein, present a patient with a cystic pancreas tumor mimicking a malignant cystic neoplasm. The patient was admitted with upper abdominal discomfort. Computed tomography showed a 64x39 mm cystic mass in the pancreas tail. She underwent distal pancreatectomy and splenectomy. In the fluid analysis of the pancreas cystic mass, the CEA and CA19-9 were 618 ng/ml and 3.9 U/ml, respectively. The resected pancreas specimen showed a 6.5 cm-sized cyst the pancreas tail. The cyst was well circumscribed and multilocular. The final pathology report of the resected pancreas specimen noted that the cyst was multilocular, and the cyst lining was showing stratified squamous epithelium covering the lymphoid tissue (containing lymphoid follicles), which was consistent with a lymphoepithelial cyst. The patient recovered uneventfully from surgery and has been doing well for the past 3 months. A differential diagnosis of cystic pancreatic lesions is important. We suggest that lymphoepithelial cysts, although very rare, may be included in the differential diagnosis of cystic pancreatic tumors.

The stomach is the most common site of gastrointestinal tract lymphoma, while synchronous mucosa-associated lymphoid tissue (MALT) lymphomas of the stomach and duodenum are very rare. A literature review found no reported case of synchronous gastroduodenal MALT lymphomas with involvement of the bone marrow and spleen. Here, we describe the case of a 62-year-old male who was diagnosed with synchronous MALT lymphomas of the stomach and duodenum based on upper gastrointestinal endoscopy and pathology. Other staging evaluations, including colonoscopy, abdominopelvic and chest computed tomography (CT), 18F fludeoxyglucose-positron emission tomography (FDG-PET), and a bone marrow examination, showed involvement of the bone marrow and spleen. We diagnosed stage EIV MALT lymphoma and began systemic chemotherapy. We report the first case of MALT lymphomas arising synchronously in both the stomach and duodenum with bone marrow involvement and review the literature.
