Dear Editor,

According to the WHO classification of non-Hodgkin lymphoma, extranodal marginal zone B cell lymphomas of mucosa-associated lymphatic tissue (MALT) is defined as a group of NHL (non-Hodgkin lymphoma) that account for approximately 7–8% of all B cell lymphomas [1]. The most common location of MALT is the gastrointestinal tract. A manifestation of the uterus is a rarity and to our best knowledge, fewer than 20 case reports of marginal zone B cell lymphoma of the uterus have been reported so far in literature [2, 3].

The histological transformation into an aggressive lymphoma occurs in approximately 4% and is associated with an inferior treatment outcome [4]. MALT lymphoma is characterized by recurrent chromosomal translocations, leading to the activation of the NF-ĸB signaling pathway.

In 2011, a 60-year-old woman presented to our outpatient department with an extranodal marginal zone B cell lymphoma of the uterus. Morphologic examination of the specimen showed epithelium,...
