Introduction: Urachus carcinoma is a rare malignancy with an aggressive potential and a poor prognosis, and evidence is limited for its diagnosis and treatment. Case presentation: A 75-year-old man underwent fluorodeoxyglucose positron emission tomography/computed tomography for staging prostate cancer, and a mass (standardized uptake value max 9.5) was observed on the outside of the urinary bladder dome. T2-weighted magnetic resonance imaging showed the urachus and a low-intensity tumor, which suggested a malignant tumor. We suspected urachal carcinoma and performed total resection of the urachus and partial cystectomy. Pathological examination revealed mucosa-associated lymphoid tissue lymphoma with cells positive for CD20 and negative for CD3, CD5, and cyclin D1. After the surgery, no recurrence has been observed for more than 2 years. Conclusion:We encountered an extremely rare case of mucosa-associated lymphoid tissue lymphoma of the urachus. Surgical resection of the tumor provided an accurate diagnosis and good disease control.

“…Only 5% of patients with autoimmune diseases are diagnosed with non-Hodgkin lymphomas. Primary Sjogren’s syndrome patients are at a higher risk of lymphoma than patients with other autoimmune diseases [ 14 , 15 ]. Compared with other extra-nodal lymphomas, MALT lymphoma is always associated with SS and manifests slowly in clinical presentation [ 9 , 14 ].…”

“…The clinical picture of Sjogren’s syndrome combines symptoms of dryness of the mucosa in many parts of the body, fatigue, and arthralgia in almost all patients [ 11 ]. MALT lymphomas affect salivary glands in the context of lymphoid tissue hyperplasia associated with chronic inflammatory conditions [ 12 , 13 , 15 ]. Diet, smoking, alcohol consumption, genetic predisposition, occupational and environmental factors are also of high importance in the development of lymphomas [ 16 ].…”

Mucosa-associated lymphoid tissue (MALT) lymphoma is a type of B-cell lineage lymphoma that can affect the head and neck region. This report presents a rare case of an extra-nodal marginal zone B-cell MALT lymphoma of a sublingual gland, diagnosed in an 18-year-old male patient. The patient had a history of ranula surgical removal on the right side of the mouth. One year after surgery, the patient presented with complaints of swelling of the left parotid gland, with no significant changes found during the examination and a self-resolving outcome. Subsequently, two years later, the patient began to complain of a fast-growing cyst under the tongue. A surgical excision of the left sublingual gland and the ranula was performed, and a final diagnosis of MALT lymphoma was rendered. The patient was referred to the department of hematology for further treatment planning and follow-up.

Pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is indolent and progresses more slowly than other malignant lymphomas. The clinical features are not specific and the diagnosis can often be difficult. Here, we present two rare cases of pulmonary MALT lymphoma. Both patients were incidentally found lesions in the lungs with chest computed tomography during physical examination. They were finally diagnosed by pathological biopsy. One received complete resection, the other was treated with chemotherapy. There were no recurrence in the two patients during follow-up. We also review relevant literature to provide a better recognition of this disease.
