ABSTRACT

Mucosa‐associated lymphoid tissue (MALT), MALT lymphoma develops in the lymphoid tissue, in the mucosa or tissue that lines body organs, or in body cavities including: the gastrointestinal tract, lungs; eyes; skin; salivary glands; thyroid gland; and breasts.
MALT lymphoma accounts for approximately 6%-8% of non-Hodgkin lymphoma (NHL) cases, making it the third most common type of NHL. These lymphomas are usually slow-growing.
Studies of patients with low-grade MALT lymphoma have confirmed a high incidence of Helicobacter Pylori infection and suggest that the infection predates neoplastic transformation.
In costa rica you should always think about this diagnosis because we have a high prevalence of the Helicobacter Pylori infection.
