Abstract

Sjögren's syndrome is a chronic systemic disease, characterized by lymphocytic infiltration and destruction mainly of the salivary and lacrimal glands, resulting in xerostomia and xeropthalmia. Sjögren's syndrome patients have a 44-fold excess risk for the development of non-Hodgkin's lymphoma particularly mucosa-associated lymphoid tissue (MALT) lymphoma, prevalently affecting the major salivary glands. In this report, a rare case of MALT lymphoma of minor salivary glands in a patient with Sjögren's syndrome is described. A review of the published cases of MALT lymphoma located in the minor salivary glands of patients with Sjögren's syndrome is provided. In a 64-year-old female patient previously diagnosed with Sjögren's syndrome, an asymptomatic soft tissue mass at the palate was noticed, exhibiting rapid enlargement within one month. With a main differential diagnosis of salivary gland neoplasm or lymphoproliferative lesion, a partial biopsy was performed accompanied by proper immunohistochemical analysis. A final diagnosis of MALT lymphoma was rendered and the patient was referred for further multidisciplinary evaluation. Gastric endoscopy and biopsy revealed a Helicobacter pylori-negative gastric MALT lymphoma, while splee...Continue Reading

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
