Primary pancreatic peripheral T-cell lymphoma: A case report

Figure 1 Positron emission tomography-computed tomography findings. By using the characteristics of the tumor, the imaging agent 18F-fluorodeoxyglucose (18F-FDG) was injected into the human body, and the imaging agent was accumulated in the lesion, so that a low-density mass of 5.1 cm × 4.1 cm could be seen in the head of the pancreas, about SUV20.3. A and C: High uptake of 18F-FDG in the head of pancreas; B: Anatomical images of the head of the pancreas at computed tomography level; D: Functional images of pancreatic head at positron emission tomography level.

Figure 2 Histopathological examination of pancreatic mass the interspersed large atypical lymphoid cells were positive for pan-T cell markers.
