A Rare Case Report of Gastric Follicular Dendritic Cell Sarcoma: An Unconsidered Differential of Gastrointestinal Stromal Tumour

Follicular Dendritic Cell Sarcoma (FDCS) is a rare well - defined malignancy presenting with homogenous nodal mass. The rare occurrence of such masses at extranodal locations like the abdomen or mediastinum presents large, heterogeneous masses with regional lymphadenopathy. However, Gastrointestinal stromal tumours are relatively common tumours, but due to their overlapping imaging features with gastric follicular dendritic cell sarcoma, they should be kept as a differential, too. Stomach FDCS are very rare, and a diagnostic suspicion of the radiologist will result in an increased chance of detection and guide the patient in further management.
