Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is an uncommon tumor of the stomach that only comprises around 1-6% of all tumors of the stomach. Non-Hodgkin lymphoma more commonly affects the lymph nodes and may spread to the spleen and bone marrow, whereas extranodal non-Hodgkin lymphoma is less common. Primary gastric lymphoma is further divided based on histologic features; one of the types is MALT lymphoma, which is strongly associated with infection. The first sign of the disease is usually mimicking gastritis. However, in the case reported here, the first sign of gastric MALT lymphoma was massive gastrointestinal (GI) bleeding with hemodynamic instability in a 75-year-old male. The patient came to the emergency department and was immediately resuscitated, intubated, and admitted to the intensive care unit. Urgent endoscopy (<6 h) was done to identify the source of bleeding, which were oozing ulcerated polypoid masses; endoscopic hemostasis was done, which successfully stopped the bleeding. However, the next day, rebleeding occurred and a second endoscopic hemostasis was performed. The bleeding stopped and the patient showed gradual improvement. The biopsy result of a gastric MALT lymphoma of grade IE1 with infection warranted a treatment regimen for eradication. The patient recovered, with follow-up endoscopy at 3 months, at 6 months, and yearly thereafter with no sign of recurrence. This case shows that gastric MALT lymphoma, even at a low stage (1E1), can cause life-threatening upper GI bleeding that requires aggressive resuscitation and urgent endoscopy.

Unexpected presentation: metastatic adenoid cystic carcinoma (AdCC) of the breast masquerading as a large cystic-solid renal mass.

Adenoid cystic carcinoma (AdCC) of the breast is a rare histological subtype of breast cancer, which usually has a low propensity for metastasis and is associated with a good prognosis. AdCC metastasis to the kidney is rare, with only 29 cases reported in the literature. We report a case of a woman in her 60s with multiple right-sided large cystic-solid renal lesions after a recent diagnosis of marginal zone B-cell lymphoma.

Article Synopsis
- Mucosa-Associated Lymphoid Tissue (MALT) lymphoma, particularly gastric MALToma, is often associated with Helicobacter pylori (H. pylori) infection, though a significant number of cases occur without it.
- A study analyzed 52 patients with gastric MALToma from 2000 to 2021, finding that 48.1% were H. pylori-negative (HPN) and noted trends of increased HPN diagnoses in more recent years.
- Treatment outcomes showed that HPP patients had better responses to eradication therapy compared to HPN patients, who were more likely to receive additional chemo or radiotherapy.
- Despite these differences in treatment response, clinical features between HPP and HPN patients
Background: Acquired angioedema due to C1-inhibitor deficiency (AAE-C1-INH) is very rare compared to its prototype, hereditary angioedema. An updated characterisation of the AAE-C1-INH cohort in UK is required to inform management.
Objectives: To describe the disease burden of AAE-C1-INH, long-term prophylaxis (LTP) and the clinical, immunochemical and treatment profiles of AAE-associated diseases in UK.
Introduction: Anal Lymphoma (AL) is a rare presentation of extranodal lymphomas, characterized by occurrence in the anal area and largely understudied due to its infrequency. This study aims to address gaps in knowledge about AL's demographic and clinical profiles, treatments, and survival outcomes, leveraging data from the SEER program.
Methods: We conducted a retrospective analysis of 79 AL cases identified in the SEER database from 2000 to 2022; 36 stage I AL were identified and defined as localized primary anal lymphoma (L-PAL).

Imaging is used for lymphoma detection, Ann Arbor/Lugano staging, and treatment response assessment. [F]FDG PET/CT should be used for most lymphomas, including Hodgkin lymphoma, aggressive/high-grade Non-Hodgkin lymphomas (NHL) such as diffuse large B-cell lymphoma, and many indolent/low-grade NHLs such as follicular lymphoma. Apart from these routinely FDG-avid lymphomas, some indolent NHLs, such as marginal zone lymphoma, are variably FDG-avid; here, [F]FDG PET/CT is an alternative to contrast-enhanced CT at baseline and may be used for treatment response assessment if the lymphoma was FDG-avid at baseline.
