Pancreatic diffuse large B-cell lymphoma: a case report and literature review

"Choledochoduodenal Fistula Arising From Pancreatic Lymphoma: An Exceedingly Rare Phenomenon"

Choledochoduodenal fistula secondary to pancreatic lymphoma is a rare phenomenon, reflecting the complex relationship between lymphoproliferative disorders and gastrointestinal complications. Fistula formation should be suspected in patients with persistent liver function abnormalities and a history of treated hematological malignancies.

Primary pancreatic lymphoma: A case report and review of literature

BACKGROUND

Primary pancreatic lymphoma (PPL) is a rare tumor that mimics pancreatic adenocarcinoma, leading to diagnostic and therapeutic challenges. PPL accounts for 0.2% of all pancreatic tumors and is typically treated with chemotherapy. However, the long-term survival rates for PPL with chemotherapy and radiotherapy alone are unsatisfactory. Due to the improvements in pancreatic surgery, there is a need to reevaluate the treatment strategies for PPL.

CASE SUMMARY

A 62-year-old male presented to our clinic. A biopsy was unsuccessful, and the imaging was suggestive of pancreatic adenocarcinoma. Therefore, subtotal splenopancreatectomy was performed and histopathology was performed. He was then diagnosed with primary pancreatic diffuse large B-cell lymphoma. He received adjuvant chemotherapy and radiotherapy. Currently, the patient is alive with no evidence of disease 36 months after surgery.

CONCLUSION

The potential role of surgery in the treatment of PPL should be emphasized and added in the management protocol of early stage lymphoma.

Calcitriol Unleashed: A Rare Culprit in Hypercalcemia Associated With Rare Primary Pancreatic Lymphoma - A Case Report

Hypercalcemia of Malignancy is a complicated condition often linked to parathyroid hormone, parathyroid hormone-related peptide, or bone metastasis. This report presents a unique case of calcitriol-mediated hypercalcemia in an 89-year-old female with primary pancreatic lymphoma, highlighting the rarity and complexity of this presentation. Initially, the patient's condition was thought to be related to sarcoidosis, but the recurrence of hypercalcemia led to the discovery of pancreatic B-cell lymphoma as the underlying cause. It also emphasizes the need to explore new treatment options. Interestingly, it demonstrates the successful use of cinacalcet in treating calcitriol-induced hypercalcemia in malignancies, which could be a potential therapeutic option for such cases. It also serves as a reminder of the critical need for ongoing research and innovative therapeutic strategies to improve outcomes in managing hypercalcemia caused by malignancies. The case underscores the potential complexities of calcitriol-mediated hypercalcemia, especially in uncommon presentations like primary pancreatic lymphoma.
