Gastric marginal zone B cell lymphoma of the duodenum

Acute pancreatitis as the first manifestation of duodenal MALT lymphoma

BACKGROUND

Possibly any tumor that can cause mechanical obstruction of the distal bile duct can induce acute pancreatitis. However, acute pancreatitis as the first clinical manifestation of duodenal lymphoma is extremely rare.

OBJECTIVE

To report the case of a patient with acute pancreatitis as an extremely rare first manifestation of duodenal MALT lymphoma and possible association with erythema nodosum.

METHODS

Case report of a 66-year-old woman who was diagnosed with acute pancreatitis caused by infiltration with duodenal lymphoma.

RESULTS

Acute pancreatitis was confirmed by CT imaging. Detailed investigation revealed a duodenal mass causing pancreatic injury. Histological analysis established the diagnosis of MALT lymphoma. The patient's medical history also included erythema nodosum. Complete remission of the malignancy was achieved with chemotherapy.

CONCLUSION

This is the first published case report of acute pancreatitis caused by the growth of duodenal MALT lymphoma. An association with erythema nodosum is possible.

A rare case of primary extranodal marginal zone B-cell lymphoma of the ovary, fallopian tube, and appendix in the setting of endometriosis

Extranodal marginal zone B-cell lymphomas are uncommon. Most occur in the gastrointestinal tract. Marginal zone B-cell lymphomas of the female genital tract are rare, and few cases exist of marginal zone B-cell lymphomas of the uterus, cervix, and fallopian tubes. We report the first marginal zone B-cell lymphoma of the ovary, fallopian tube, and appendix arising in endometriosis.
