Primary lymphoma of the uterine cervix (LUCX) is extremely rare, and its diagnosis is challenging. However, its clinicopathological features have not been well characterized. Thirteen primary LUCX patients were retrospectively studied, and 54 patients from the literature were reviewed. Primary LUCX was identified in 0.22% (13/6000) of patients with uterine cervical malignancies in our institution. The patients' median age was 51 years (range: 22-85 years). All patients had a bulk of neoplasms in the uterine cervix. The median tumour diameter was 6 cm (range: 1.5-10 cm). Approximately 78.0% (39/50) of the patients initially presented with irregular vaginal bleeding or discharge. Moreover, 86.7% (39/45) had Ann Arbor stage I or II. Diffuse large B-cell lymphoma, not otherwise specified, was the most common type, accounting for 85.0% (57/67) of primary LUCX cases. Follicular lymphoma (7.5%, 5/67), extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (4.5%, 3/67), mantle cell lymphoma (MCL), blastoid variant (1.5%, 1/67), and peripheral T-cell lymphoma (1.5%, 1/67) were occasionally observed. Three patients (7.1%, 3/42) with DLBCL, NOS died from the disease during the follow-up period. Their 5-year overall survival (OS) rate was 93.5%. The patient with MCL, blastoid variant in our present cohort died of the disease 33 months after diagnosis. Primary LUCX is an extremely rare condition. The clinical symptoms are non-specific. DLBCL, NOS is the most common histologic type, showing a favourable outcome with accurate diagnosis and timely and optimal treatment.
