Breast lymphoma: General review.

BACKGROUND: Lymphoma of the breast can be classified as either primary breast lymphoma (PBL) or secondary to systemic lymphoma (SBL). PBL is a rare disease with Diffuse Large B cell Lymphomas (DLBCL) being the most common subtype. OBJECTIVES: In the current study, we represented eleven cases diagnosed with breast lymphoma in our trust; two of them had PBL and nine had SBL. We focused mainly on the clinical presentation, diagnosis, management and outcomes. METHODS: We did this retrospective review for all breast lymphoma patients who were diagnosed in our trust during the periods from 2011-2022. Patients' data were obtained from the hospital recording system. We followed up these patients thus far to identify the outcome of treatment in each patient. RESULTS: Eleven patients were included in our review. All patients were females. Average age of diagnosis was 66.1 ± 13 years of age. Eight patients were diagnosed with DLBCL, two patients were diagnosed with follicular lymphomas, and the last one had lymphoplasmacytic lymphoma. Chemotherapy +∕- radiotherapy was the standard treatment regimen in all patients. Four patients passed away within one year of chemotherapy, five patients achieved complete remission, one patient had two relapses and is still under treatment, while the last patient was diagnosed recently and still awaiting treatment. CONCLUSION: Primary breast lymphoma is an aggressive disease. The treatment for PBL is mainly systemic with chemoradiotherapy. The role of surgery is now limited to the diagnosis of the disease. Early diagnosis and proper treatment are crucial for the management of such cases.

Thyroid Lymphoma: Case Series Review.

BACKGROUND: Primary thyroid lymphoma (PTL) is a rare malignancy accounting for about 5% of all thyroid malignancies and less than 2% of extra-nodal lymphomas. Diffuse B-cell lymphoma is the most common pathological subtype of PTL. PATIENTS AND METHODS: This is a retrospective review of all patients diagnosed with thyroid lymphoma in our hospital during the period from 2011 to 2021. All patients had clinical, radiological, and pathological evaluation. We have followed up these patients since diagnosis till now. RESULTS: Eight patients were included in our review. Four patients were males and four were females. Mean age at diagnosis was 63 ± 32 years of age. Diagnosis was confirmed only with tissue histology. Six patients had stage IIE disease and two had stage IVE disease. Four patients had disease related mortality. Of the other four patients, two had chemotherapy (RCHOP) and one had local radiotherapy; all achieved complete remission, and the last one had hemithyroidectomy to relieve airway compression and still under treatment. CONCLUSION: Primary thyroid lymphoma is rare malignancy of the thyroid gland. Advanced stage and age at the time of diagnosis, the presence of compression manifestations, large tumor mass, and presence of distant metastasis, all are poor prognostic criteria. Our knowledge of the disease pathology, diagnosis, and management is still limited and more research studies are required.
