Two cases of low-grade follicular lymphoma, with marginal zone differentiation and/or with high proliferation rate in one of them, are reported with transformation into high grade B-cell and B-lymphoblastic lymphomas. The contribution of these features to the transforming process, although previously described, is infrequent, and has not been deciphered to date.

Thyroid tissue is sensitive to the effects of endocrine disrupting substances, and this represents a significant health concern. Histopathological analysis of tissue sections of the rat thyroid gland remains the gold standard for the evaluation for agrochemical effects on the thyroid. However, there is a high degree of variability in the appearance of the rat thyroid gland, and toxicologic pathologists often struggle to decide on and consistently apply a threshold for recording low-grade thyroid follicular hypertrophy.

: A Warthin tumor is a benign salivary gland neoplasm, mostly found in the parotid gland. The number of reported Warthin tumors has increased over the years due to better diagnostic modalities and health system modernization. Warthin tumor rarely transforms into a malignant tumor; in this work, we present all cases reported in the English literature of different types of lymphomas within Warthin tumors.

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.

Purpose: Activating T cell costimulatory receptors is a promising approach for cancer immunotherapy. In preclinical work, adding an OX40 agonist to in situ vaccination (ISV) with SD101, a TLR9 agonist, was curative in a mouse model of lymphoma. We sought to test this combination in a Phase I clinical trial for patients with low-grade B cell lymphoma.

Background/aim: Follicular lymphoma (FL) is the most common indolent non-Hodgkin lymphoma worldwide. Patients can have a wide range of clinical features and behavior which does not necessarily correlate to histologic grade or Ki-67 proliferation index. We hypothesized that patients with low grade but high proliferative index (LG/HP) FL have a more aggressive disease course.
