We report computed tomography (CT) findings for a rare case of follicular dendritic cell sarcoma of the greater omentum from a 47-year-old female patient. The tumor presented ash a palpable mass lesion in the umbilical region for the last two months. Multidetector CT scan of the abdomen showed a 14-cm soft-tissue mass with calcification and necrosis within the greater omentum. As a result, a follicular dendritic cell sarcoma should be considered in the differential diagnosis of a solitary omentum mass, especially one with coarse and chunk-like calcifications.

Follicular dendritic cell-secreted protein (FDC-SP) is produced by follicular dendritic cells, periodontal ligament and junctional epithelium (JE). JE exists immediately apical to the bottom of the pocket and binds enamel with hemidesmosomes to protect the periodontium from bacterial infection. To analyze the transcriptional regulation of the FDC-SP gene by interleukin-6 (IL-6), we performed real-time PCR, Western blotting, immunofluorescence, luciferase (LUC) assays, gel mobility shift and chromatin immunoprecipitation (ChIP) assays using Ca9-22 and Sa3 gingival epithelial cells.

Follicular dendritic cell sarcoma (FDCS) is a rare neoplasm requiring a high index of suspicion, especially on small biopsies. Smooth muscle myosin heavy chain (SMMHC) is a common immunohistochemical (IHC) stain that has been reported to mark normal nodal follicular dendritic cells (FDCs). We hypothesize that SMMHC can be a sensitive marker for FDCS and aim to compare its performance with established markers of FDCS.

Constructing artificial tertiary lymphoid structures (TLSs) opens new avenues for advancing cancer immunotherapy and personalized medicine by creating controllable immune niches. Mesenchymal stromal cells (MSCs) offer an ideal stromal source for such constructs, given their potent immunomodulatory abilities and accessibility. In this study, we explored the potential of adipose-derived MSCs to adopt TLS-supportive phenotypes and facilitate lymphocyte organization.

Tertiary lymphoid structures (TLS) are organized immune cell aggregates that arise in chronic inflammatory conditions. In cancer, TLS are associated with better prognosis and enhanced response to immunotherapy, making these structures attractive therapeutic targets. However, the mechanisms regulating TLS formation and maintenance in cancer are incompletely understood.

Lymphomas of T-follicular helper origin (T-follicular helper-cell lymphoma [TFHL]) are often accompanied by an expansion of B-immunoblasts, occasionally with Hodgkin/Reed-Sternberg-like (HRS-like) cells, making the differential diagnosis with classic Hodgkin lymphoma (CHL) difficult. We compared the morphologic, immunophenotypic, and molecular features of 15 TFHL and 12 CHL samples and discussed 4 challenging cases of uncertain diagnosis. Compared with CHL, TFHL disclosed more frequent sparing of subcortical sinuses, high-endothelium venule proliferation, dendritic cell meshwork expansion, T-cell atypia, and aberrant T-cell immunophenotype.
