Primary lymphomas of the thyroid are rare tumours, representing less than 5% to 15% of thyroid cancers. These lymphomas develop on a pre-existing thyroid disease, notably Hashimoto's thyroiditis, or as a secondary site of a disseminated lymphoma. This pathology is aggressive and presents as a painful, rapidly evolving goitre with signs of compression. The most common histological types are non-Hodgkin's lymphoma type B. We report a case of thyroid non-Hodgkin's lymphoma of the MALT type in a 71 year old woman with a specific history; the positive diagnosis was made thanks to a histological study of the surgical specimen completed by an immunohistochemical study on paraffin sections. The postoperative clinical course after six years was favourable, with no local recurrence or distant metastasis. Keywords: Goiter; Primary Lymphoma; Thyroid; MALT; Immunohistochemistry

Abstract Background: Primary non-Hodgkin’s lymphoma (NHL) of the orbit is rare. Orbital NHLs show good response to both radiotherapy (RT) and chemotherapy, and hence, the emphasis should be to ensure maximum cure rate with minimum morbidity. In this study, we present the clinical profile and treatment outcomes of patients with NHL who had initial presentation in the orbit. Materials and methods: In this retrospective analysis, case records of patients with a diagnosis of NHL of the orbit were analysed from January 2005 to January 2015. Patients were worked up and staged according to the Ann Arbor system. Patients with large tumours were initially given chemotherapy with CHOP regimen (cyclophosphamide, vincristine, adriamycin and prednisolone) three weekly for 4–6 cycles. Patients with residual disease were given RT 20–30 Gy at 2 Gy per fraction. RT when given as a primary treatment consisted of 36–45 Gy at 1·8–2 Gy per fraction on either Cobalt 60 machine or linear accelerator. Results: A total of 52 patients with diagnosis of orbital NHL were included in this study. Median age at presentation was 57 years (range 13–71). Left, right and bilateral orbit was involved in 21 (40%), 28(54%) and 3(6%) patients, respectively. Low- and high-grade pathology was seen in 39(75%) and 13(25%) patients, respectively. On immunohistochemistry, 23(44%) tumors were CD 20 positive. After staging, 33 (63%) patients had stage I disease. Median tumour size was 4·0 × 3·2 × 1·5 cm (1·7 × 1·7 × 1·4 cm to 5·8 × 4·0 × 4·7 cm). Primary RT was given to 7(13%) patients. Upfront chemotherapy was given in 45(86·5%) patients, out of which 24 had stage I disease. RT consolidation was done in 26 (50%) patients for residual disease after chemotherapy. Median follow-up was 88 months (range 29–183 months). Relapse occurred in 6(9·6%) patients; 2 local; 2 local + distant and in 2 distant alone. These patients were successfully salvaged with systemic chemotherapy and local RT. One patient died due to neutropenia. Overall survival in this series was 96%. Conclusions: Excellent local control was achieved with initial chemotherapy followed by RT for primary orbital NHL with minimal toxicity. We recommend a dose of 36–40 Gy for definitive RT and 30 Gy for lymphoma following chemotherapy using 2 Gy/fraction for Indian patients who present with bulky tumours. RT should be incorporated in treatment of orbital NHL whenever possible as it is safe, effective and is associated with minimal complications.

Background: Out of the various malignant tumours originating from the lymphatic hematopoietic system, lymphoma is one such important entity. It is divided into Non-Hodgkin’s Lymphoma (NHL) and Hodgkin Lymphoma (HL) depending on its cell source. A very rare type of malignant variant of lymphoma is the primary splenic lymphoma, involving exclusively the spleen and splenic hilar lymph nodes. Moreover, splenic marginal zone lymphoma (SMZL) is even more infrequent. SMZL is an uncommon chronic B lymphocyte proliferative disease, which only accounts for about 1–2% of all non-Hodgkin’s lymphoma. The mean age of SMZL incidence is about 65 years. There is no known significant gender predominance. A quarter of patients with early diagnosed SMZL have known to have vague symptoms like abdominal pain and distention; and other patients may be accompanied by loss of weight, malaise, cachexia, splenomegaly, or other manifestations. Conclusion: Although, a good prognostic outcome is what is usually expected from most patients of Splenic Marginal Zone Lymphoma who undergo splenectomise, an aggressive transformation leading to a worse direction cannot be ruled out. SMZL is very challenging to be diagnosed pre-operatively due to the lack of specificity in clinical presentation.

Highlight:A 32-year-old male patient suffered mediastinal non-hodgkin's lymphoma metastatic to the right atrium which mimicked right atrial myxoma.The patient died of suspected mediastinal NHL thromboembolism that spread in the right atrium. Abstract:In this case report, the anatomical pathology results in the form of B cell type LNH, but at the age of 32 years and the risk factor in this patient was a former active smoker. In the anatomical pathology results, the results of the B-High Grade Cell Type LNH were also obtained. B-cell type non-hodgkin’s lymphoma can be mutated in the MYC gene (v-myc avian myceloctomatosis viral oncogene homolog) and the BCL-2 and BCL-6 (B-cell lymphoma) genes. If this morphology is found, then the patient's prognosis is poor. Most of these patients were males and the incidence was in the mediastinal area. Mediastinal NHL could develop and enlarge to involve the heart and pericardium. The spread could occur directly and lymphogens. These metastatic tumors were often misdiagnosed with atrial myxoma. In this case report, exploration of the right atrium and open mediastinal biopsy was performed. An open biopsy of the mediastinum revealed a mediastinal mass that enlarged to enter the right atrium. Atrial myxoma was not found. Primary lymphoma growth could also occur in the heart. This condition was called primary cardiac lymphoid (PCL). This case was very rare and was often considered an atrial myxoma. The patient died 10 days after discharge from the hospital. While the patient was eating, the patient had a seizure and the patient was immediately taken to the emergency department of Dr. Soetomo General Academic Hospital, Surabaya, and entered the ER (Resuscitation) ER room, but the patient died after being assisted for approximately two hours. Most likely the cause of the patient's death was a thromboembolic tumor in the right atrium that was released, so that it entered the bloodstream of the brain, causing the patient to have seizures. It was suspected that the cause of the patient's death was the presence of a tumor thrombus that separated into an embolism from the right atrium due to the large size of the tumor. Patients suffering from high rate NHL had a greater percentage of suffering from tumor thromboembolism as many as 10.6% compared to the Low type and Hodgkins lymphoma (LH) (5.8% and 7.25%).
