Canine lymphoma is a commonly reported neoplasia and, in most dogs, arises from lymph nodes before spreading to other organs. Renal lymphoma rarely occurs, and kidneys usually are a secondary site of origin. Primary renal lymphoma is infrequently described in the veterinary literature. In this study, we present a rare case of primary renal lymphoma in a dog and a review of similar cases. A 3-year-old male dog was admitted due to anorexia, weakness and vomiting. Clinical examination revealed bilaterally enlarged kidneys. Imaging demonstrated the presence of multiple renal masses. Cytology of abdominal fluid and kidneys led to the diagnosis of large cell lymphoma. Histopathology and immunohistochemistry on tissue samples taken from the kidneys confirmed the cytological diagnosis of lymphoma and categorized it as primary bilateral renal large B-cell lymphoma (LBCL).

B cell immunity carries the inherent risk of deviating into autoimmunity and malignancy, which are both strongly associated with genetic variants or alterations that increase immune signaling. Here, we investigated the interplay of autoimmunity and lymphoma risk factors centered around the archetypal negative immune regulator TNFAIP3/A20 in mice. Counterintuitively, B cells with moderately elevated sensitivity to stimulation caused fatal autoimmune pathology, while those with high sensitivity did not.

Celiac disease (CD) is a chronic illness. Blood testing for tissue transglutaminase antibodies is the initial screening test for the diagnosis of CD, and upper gastrointestinal endoscopy and duodenal/jejunal biopsy are used to confirm CD. Intussusception (IS) is the process in which a proximal segment of the bowel invaginates through the lumen of a distal segment.

Background: Systemic lupus erythematosus is a multi-organ autoimmune disorder that is treated by immunosuppressive agents that weaken the immune defense against opportunistic pathogens and latent infections such as strongyloidiasis. Herein, we report the case of a 43-year-old woman known to have systemic lupus erythematosus who presented with gastrointestinal symptoms, edema, and bone pain 2 months after receiving immunosuppressive treatment.
Case Presentation: A 43-year-old Iranian female known to have systemic lupus erythematosus and antiphospholipid syndrome presented with abdominal pain, nausea, vomiting, and generalized edema.

Various aggressive lymphomas entities have been associated with immunodeficiency. To provide further evidence that also MYC-negative high-grade B-cell (formerly Burkitt-like) lymphoma with 11q aberrations comprises an immunodeficiency-related subtype, we here conducted a comprehensive pathological and genetic workup of a 25-year-old patient with this type of lymphoma and simultaneous papillary renal cell carcinoma. The patient developed both malignancies following extensive childhood immunosuppression and a kidney transplant.
