Stage IE primary malignant lymphomas of the uterine cervix

Epidemiological features for primary lymphoma of the female genital tract patients and development of a nomogram to predict survival

BACKGROUND

Primary lymphoma of the female genital tract (PLFGT) is a sporadic extranodal lymphoma. Its epidemiology and prognosis are not fully recognized. Our study aimed to construct and validate prognostic nomograms for predicting survival for patients with PLFGT.

METHODS

Incidence rate from 1975 to 2017 and patients with PLFGT from 1975 to 2011 in the Surveillance, Epidemiology and End Results (SEER) database were retrospectively reviewed. The nomograms of overall survival (OS) and disease-specific survival (DSS) were established according to the multivariate Cox regression analyses. The concordance index (C-index) and calibration plots were used to demonstrate its robustness and accuracy.

RESULTS

A total of 617 PLFGT patients were identified. The overall incidence of PLFGT is 0.437/1,000,000 (adjusted to the US standard population in 2000) from 1975 to 2017. Age, histological subtype, Ann Arbor Stage, and therapeutic strategy were identified as independent prognostic factors for OS and DSS by multivariate Cox regression (p < .05). Nomograms to predict 1-, 5-, and 10-year OS and DSS were established. The C-index and calibration plots showed a good discriminative ability and an optimal accuracy of the nomograms. Patients were divided into three risk groups according to the model of OS.

CONCLUSIONS

The incidence of PLFGT has increased in the past 40 years, and the nomograms were developed and validated as an individualized tool to predict OS and DSS for all PLFGT patients and DLBCL patients. All patients are divided into three risk groups to assist clinicians to identify patients at high-risk and choose the optimal individualized treatments for patients.HighlightsThe incident of PLFGT and its subtypes were calculated and compared.Nomograms were constructed to predict the 1-, 5-, and 10-year OS and DSS.Patients are divided into the low-risk, medium-risk, and high-risk according total score of the nomogram.

Unusual primary location of non-Hodgkin lymphoma in the uterine body with compressive form: About case

INTRODUCTION

Primary non-Hodgkin's malignant lymphoma (NHML) of the uterine body is an extremely rare localization since only eleven cases have been reported in the literature.

CASE PRESENTATION

We report a case of primary NHML of the uterine body discovered during a hysterectomy performed for a uterine mass. The primary character of NHML of the uterine body was retained in view of the absence of extra-genital localization in the clinical, biological and radiological workup (Ann Arbor stage IE) and there were no signs of recurrence during follow-up. The patient received anti-CD20 immunochemotherapy (rituximab-CHOP and rituximab-VCAP combinations) and at 12 months follow-up, she is in complete remission.

DISCUSSION

The diagnosis of primary and isolated NHML of the uterine body is based on a clinical and further examination and regular follow-up for several months. The treatment is not codified; surgery, poly-chemotherapy and radiotherapy are the different therapeutic modalities. Rituximab-CHOP immunochemotherapy is currently the reference treatment for primary malignant lymphomas of the uterine body particularly in young patients who wish to become pregnant. The prognosis depends mainly on two factors: age and Ann Arbor stage.

CONCLUSION

Primary uterine lymphomas are rare tumors of unknown etiopathogeny and of non-specific clinical presentation, the role of the various treatments remains difficult to evaluate due to the small number of published cases.

Primary lymphomas of the intraabdominal solid organs and the gastrointestinal tract: spectrum of imaging findings with histopathological confirmation

Unlike nodal lymphoma, primary lymphomas of the intraabdominal organs are uncommon neoplasms whose diagnosis may be challenging in certain clinical circumstances. Despite this difficulty for imaging diagnosis, there are several imaging features on ultrasonography, computed tomography, magnetic resonance imaging, and positron emission tomography that may suggest the correct diagnosis. The scope of this review is to describe and illustrate the imaging features of primary lymphoma of intraabdominal organs providing clues to the diagnosis, together with their pathological correlations.

Primary diffuse large B cell lymphoma of the uterine cervix successfully treated by combined chemotherapy alone: A case report

RATIONALE

Primary lymphomas of the uterine cervix are a rare disease. They are often misdiagnosed because of their rarity and because they can be easily confused with a squamous cell carcinoma of the cervix, as they are usually presented as exophytic mass with vaginal bleeding as their most common symptoms. Nevertheless, considering that both the prognosis and the treatment are completely different between them, differential diagnosis should be taken into account.

PATIENT CONCERNS

A case of a 51-year-old woman with a primary diffuse large B-cell lymphoma of the cervix is presented.

DIAGNOSES

Diagnosis of this tumor was a challenge for pathologists and clinicians, as four biopsies were needed to achieve a final diagnosis.

INTERVENTIONS

Patient was successfully treated with combined Rituximab and chemotherapy (R-CHOP) alone.

OUTCOMES

Complete remission, confirmed through biopsy, was reached after six courses of chemotherapy. At 2-years follow up, patient is alive and free of disease.

LESSONS

Considering that the prognosis and treatment of primary malignant lymphoma of the cervix are completely different than that of the squamous cell carcinoma, awareness of this disease should be considered in the differential diagnosis.

Extranodal NK/T-cell lymphoma, nasal type of the uterine cervix: A case report

We report a rare case of extranodal NK/T-cell lymphoma, nasal type of the uterine cervix that showed cytologic features mimicking cervical cancer. A 65-year-old woman presented with vaginal bleeding. Gynecological examination revealed a bulky tumor of the cervix. A conventional Papanicolaou-stained cervical smear showed hypercellularity consisting of numerous variably sized cohesive clusters that mimicked epithelial tumors, with a necrotic and inflammatory background. A small number of individually scattered cells were also identified. These scattered cells showed pleomorphic, often cleaved, or horseshoe-shaped nuclei and pale cytoplasm. Biopsy specimens revealed a diffuse growth of atypical cells with an angiocentric pattern. Extensive necrosis and infiltration of inflammatory cells were present. There were numerous mitotic figures. The tumor cells were positive for CD45RO, CD3ε, CD56, granzyme B, TIA-1, CD7, and Epstein-Barr virus (EBV)-encoded small RNA (EBER) by in situ hybridization, and negative for cytokeratin, chromogranin A, synaptophysin, CD4, CD5, CD8, CD20, and CD30. Based on these findings, this tumor was diagnosed as extranodal NK/T-cell lymphoma, nasal type of the uterine cervix.

The importance of re-examination with deep biopsies in diagnosing cervical malignancies despite multiple negative pathology reports: A case report

•

The role of gynecological examination in diagnosis genital cancer is important as in this case (a woman with stony cervix and frozen pelvis).

•

When we have frozen pelvis and fix stony cervix, taking multiple deep biopsies in spite of previous negative pathologic reports, is necessary.

•

Reviewing the slides by qualified pathologists can help us to achieve true diagnosis when we the physical exam does not match with histopatologic results.

•

Lymphoma should be always in our mind to remind the pathologists.

Introduction

Clinical symptoms of female genital tract lymphoma are often non-specific, and mimic other more common gynecological malignancies. Diagnosis can only be confirmed by histology.

Case presentation

We report the case of a 48-year-old multiparous woman who underwent subtotal hysterectomy because of enlarged myomatous uterus and persistent heavy vaginal bleeding. “2 months later”, postoperative pelvic and abdominal CT scan performed because of flank pain, revealed bilateral hydronephrosis. Pelvic and colposcopic exam and cervical biopsy under anesthesia showed benign histology, as reported by two pathologists. Referral to a third pathologist and immunohistochemical (IHC) exam revealed malignant lymphoproliferative disorder.

Conclusion

Despite multiple negative pathology reports of the cervical biopsies, bimanual pelvic exam with deep biopsies by a gynecologist, allowed accurate final diagnosis of this unusual case.

An unusual cervical tumor as presentation of a non-hodgkin lymphoma

Rare cervical cancers are responsible for a minority of cases encountered by a clinician. However, behavioral patterns, management, and prognosis of certain rare cervical cancers differ from either squamous carcinomas or adenocarcinomas. Here we present a case of a locally advanced cervical tumor as a presentation of an extranodal cervical non-Hodgkin lymphoma (NHL), with a review of the current literature.

Primary gynecologic lymphoma: imaging findings

OBJECTIVE

The purpose of this article is to review the imaging features, particularly on MR images, useful in identifying primary gynecologic lymphoma.

CONCLUSION

Primary gynecologic lymphoma is rare. Nonetheless, the distinction between primary and secondary involvement is important because of critical differences in prognosis and treatment. The prospective diagnosis of primary gynecologic lymphoma enables immediate chemotherapy or radiation therapy and avoids unnecessary surgery, which delays treatment. Diagnostic imaging can be key in differentiating lymphoma from the far more common pelvic malignancies.

Primary cervical lymphoma: a rare presentation to a genitourinary medicine clinic

Summary

Primary non-Hodgkin's lymphoma of uterine cervix is a rare diagnosis. We present the case of a 47-year-old woman who presented to our genitourinary (GU) medicine service complaining of a malodorous discharge. Speculum examination revealed a necrotic mass on the cervix. She was referred urgently to gynaecology and subsequent histology revealed a diffuse large B-cell lymphoma. She received six cycles of RCHOP chemotherapy and is now in clinical remission. This case highlights the need for GU medicine physicians to remain vigilant with regard to possible gynaecological malignancies in all of our patients, the need for medical backup within GU medicine clinics and for clear pathways of referral to other specialists to exist.

Primary malignant lymphoma of the uterine cervix

Primary malignant lymphoma of the female genital tract is an extremely rare clinical entity. We report a case of primary non-Hodgkin lymphoma of the uterine cervix. An 85-year-old woman presented with abnormal genital bleeding. A colposcopic examination revealed a mass in the uterine cervix. No other lesions were detected by the whole-body CT, gallium scintigraphy and bone marrow examination. The histological examination and immunohistochemical staining of the cervical biopsy material confirmed a diagnosis of diffuse large B cell lymphoma of the uterine cervix, clinical stage 1E (according to the Ann Arbor Staging Classification for Lymphomas). The patient was treated with rituximab, cyclophosphamide, hydroxydaunorubicin, vincristine (oncovin) and prednisone. Her family refused surgery and involved field irradiation. She was in good condition but after 5 months she expired due to myocardial infarction.

Full-term pregnancy and vaginal delivery after treatment for non-Hodgkin's lymphoma of the cervix and lower uterine segment: a case report

BACKGROUND

Primary gynaecologic non-Hodgkin's lymphomas are rare. We present a case of primary large B-cell lymphoma localized to the lower uterine segment and endocervical stroma that was successfully treated with chemotherapy and immunotherapy. Treatment was followed by a disease-free interval and successful term vaginal delivery.

CASE

A 21-year-old nulliparous woman presented with dysfunctional uterine bleeding. Radiologic assessment of a posterior lower uterine segment mass and pathologic evaluation of cervical biopsies demonstrated diffuse large B-cell lymphoma involving the endocervical stroma. The patient was treated with chemotherapy and immunotherapy. She had a normal, uncomplicated full-term pregnancy and spontaneous vaginal delivery six years after treatment.

CONCLUSION

Aggressive diagnosis and treatment of primary non-Hodgkin's lymphomas of the cervix do not preclude the possibility of a successful pregnancy and term vaginal delivery.

Rare primary extranodal lymphomas: diffuse large B-cell lymphomas of the genital tract

Primary non-Hodgkin's lymphoma (NHL) of the genital tract is a rare entity. Etiology and pathogenesis of these NHLs are unknown, although there might be a possible association between chronic inflammation and lymphomas. The most common histological subtype is the diffuse large B-cell lymphoma. We report two cases of uterine lymphoma and one case of prostate lymphoma in this paper. The symptoms and the differential diagnosis are also discussed. Because of the low incidence, there is no widely accepted consensus on its treatment. We demonstrate that the rituximab and CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone; R-CHOP) chemoimmunotherapy is a good and tolerable treatment option in all cases. The two young patients are disease-free nowadays; the older patient with poor prognostic histological-type lymphoma relapsed in a short time and died after second relapse. A multicenter analysis is necessary to evaluate the long-term results of chemoimmunotherapy in these rare extranodal lymphoma entities.

Hodgkin's lymphoma relapse in the uterine cervix 15 years after the initial cure

Uterine cervix is an uncommon site for the presentation of Hodgkin's lymphoma. We describe a 62-year-old woman who developed an unusual relapse of classical Hodgkin's lymphoma, a nodular sclerosis subtype, in the uterine cervix, with propagation to the vaginal wall. She relapsed 15 years after achieving a complete remission of Hodgkin's lymphoma, initially in clinical stage IVB. This late relapse of the Hodgkin's lymphoma was in the clinical stage IEB and the treatment was initiated according to ABVD regimen. After the second course, lethal outcome ensued due to progression of the renal failure, which ensued in the meantime, probably as an adverse effect of the previous therapy.

FDG-PET Is Useful in Staging and Follow-up of Primary Uterine Cervical Lymphoma

A 35-year old woman presented with vaginal bleeding. She had a normal gynecologic examination and Papanicolaou test. A CT scan of the pelvis showed a cervical mass, which on biopsy proved to be B-cell lymphoma. PET before preoperative staging demonstrated a large area of increased FDG uptake in the pelvis, corresponding to the mass seen on the CT scan. There were no other abnormal F-18 FDG avid sites. The patient received chemotherapy followed by total abdominal hysterectomy. Histopathology was consistent with large B-cell lymphoma of the uterine cervix. Posttherapy CT scan and PET scan showed no evidence of active and or residual disease.

Primary follicular lymphoma of the cervix uteri: a review

Primary non-Hodgkin's lymphoma of the cervix is a rare disease, of which a subgroup of follicular lymphoma constitutes only 8.5%. There is not an established treatment protocol neither for primary cervical lymphoma nor for its follicular subgroup. We presented a case with Ann Arbor stage IEA (Extra-nodal involvement and absence of weight loss, fever, night sweat) primary follicular lymphoma of the cervix. She was treated with chemotherapy followed by pelvic radiotherapy. Upon relapse with a nodal neck mass, she was treated with rituximab alone. She remained well for 23 months after rituximab. In the 39 months of follow-up, there was no evidence of disease. In the light of our case, we reviewed the reported cases of primary follicular lymphoma of the cervix while discussing their treatment protocols and the cases of primary cervix lymphoma treated with rituximab.

Primary lymphomas of the cervix and uterus: the University of Pennsylvania's experience and a review of the literature

Primary lymphomas of the cervix and uterus are rare with approximately 150 cases reported in the world literature to date. Appropriate diagnosis is often delayed until the post-operative setting as clinical and radiographic presentations are non-specific. Several sub-types of lymphoma arising primarily in the cervix or uterus have been reported with diffuse large B-Cell lymphoma (DLBCL) being the most frequent. Due to the low incidence of this disease, no randomized clinical trials exist to help guide treatment. This study reports the experience of four patients with primary lymphomas of the uterus and cervix that reflect the heterogeneity of cases reported in the literature to date. The patients had a mean age at diagnosis of 46 (range 35 - 56) and presented with abnormal uterine bleeding. One patient was diagnosed by total abdominal hysterectomy (TAH), two patients were diagnosed by cervical biopsy and one patient was diagnosed by endometrial biopsy. Three patients had DLBCL and one patient had marginal zone lymphoma (MZL). All patients had stage IIE disease. Of the patients with DLBCL, one received chemotherapy followed by TAH and two received TAH followed by chemotherapy. Two of these three patients remain disease-free post-initial therapy with the third now disease-free post-salvage therapy and autologous stem cell transplant. The patient with MZL was treated with TAH alone and remains disease-free. Based on the case series and a review of available literature, primary lymphomas of the uterus or cervix are rare and require an individualized approach to treatment. In general, patients with limited stage disease should be treated with localized and systemic therapy to optimize chances of cure.

Conservative management in primary genital lymphomas: the role of chemotherapy

BACKGROUND

The female genital lymphomas are an extremely rare disease accounting for less than 0.5% of gynecological cancers and for 1.5% of all NHL. Because of their low incidence there is no widely accepted consensus on its treatment. Literature data support a radiotherapy-based treatment in case of primary genital lymphomas stages I-II. The role of chemotherapy as neoadjuvant or exclusive treatment is still to be defined.

METHODS

From 1984 to 2003, the treatments in our institution of 19 patients with genital lymphoma were reviewed. Nine women presented with cervical, 3 with vaginal, 1 with cervical-vaginal, 2 with vulvar and 4 with ovarian lymphoma. Seven were staged IE, nine IIE, one IIIE and two IVE. As a whole, chemotherapy was used in 18/19 cases: chemotherapy was proposed as first line treatment in 12 cases, while surgery in 7 (followed by chemotherapy in 6 cases).

RESULTS

Primary chemotherapy alone obtained a complete response (CR) in 9/12 patients; pathological complete response (pCR) was confirmed in 3 operated patients out of 9. Partial response (PR) was observed in 3, requiring radiotherapy. Chemotherapy obtained CR after incomplete surgical debulking in 3 out of 4 cases. Two patients relapsed in the group treated with chemotherapy alone. Both have been salvaged by further chemotherapy. Only one patient deceased due to her tumor after surgery and chemotherapy.

CONCLUSION

The use of exclusive chemotherapy obtained promising results not only as regards survival rates but also for reducing the need of radiotherapy. A conservative management based on exclusive chemotherapy in primary genital lymphoma stages I-II may be attempted in selected patients desiring pregnancy.

Primary uterine lymphoma: report of 2 cases and review of literature

Primary uterine non-Hodgkin's lymphoma is a rare malignancy. We here describe 2 patients who presented with cervical growth, stage IE, diffuse large B cell histology. Both were treated with chemotherapy followed by involved field radiotherapy in 1 patient. They achieved complete clinical and radiological response. Data of 101 patients collected from the literature are reviewed.

Primary malignant lymphoma of uterine cervix

Primary malignant lymphoma of the uterine cervix is a rare disease. Malignant lymphoma can be clinically and histopathologically misdiagnosed for the infrequent presentation in this are. A case of 56-year-old woman with uterine cervical tumor with infiltration to both parametria is presented. A biopsy was performed and histopathological studies reported a large cell B lymphoma. After the diagnosis CT abdominal, pelvic and thoracic scan was performed and shows infiltration to posterior bladder without evidence of disease in lymph nodes or another organ. The patient was treated with chemotherapy and radiotherapy. Six month after finish the treatment is well and free of disease.

Lymphomas of the female genital tract: a study of 186 cases and review of the literature

Malignant lymphomas in the female genital tract are rare, and those arising from this tissue system are extremely uncommon. Most pertinent reports lack clear references to the accepted classifications or failed to apply immunomarkers and molecular techniques for a reliable diagnosis. We analyzed a large group of patients with primary and secondary lymphomas of the female genital tract classified on the basis of the recent WHO consensus. A total of 186 patients with malignant lymphoma detected in the female genital tract were selected from the files of the Kiel Lymphoma Registry covering the period of 1974 to 2004. Stringent criteria were applied to separate systemic versus secondary lymphomas. All cases were reviewed on the basis of conventionally stained sections, relevant immunohistochemistry using the alkaline phosphatase/anti-alkaline phosphatase technique, and clinical information, as far as available. When required, gene rearrangement analysis was performed, including TCR-gamma chain gene and the three FR fragments of the IgG heavy chain gene. In addition, typical chromosomal translocations were detected by means of the FISH technique to verify the diagnosis, where needed. Thirty-seven percent of the cases were systemic lymphomas and 63% were mostly extranodal lymphomas primary to the female genital tract. The adnexa were involved in 87 cases, followed by uterine corpus in 23 cases, uterine cervix in 17 cases, portio in 9 cases, vagina in 11 cases, and vulva including clitoris in 8 cases. In 31 cases, two or more adjacent sites were involved. In both (primary and secondary) groups, the adnexa were the prevailing site of involvement. As expected, the overwhelming majority of cases were of B phenotype. The most frequent type of lymphoma proved to be diffuse large B-cell lymphoma, closely followed by follicular lymphoma, including all 3 grades of malignancy. Burkitt lymphoma showed a rather similar frequency. Marginal zone lymphoma occurred exclusively as primary lesions in the uterine mucosa. Lymphoplasmacytic lymphoma was restricted to the vulvo-vaginal area and occurred in women over 60 years of age. In conclusion, our study provides a thorough overview of various types of lymphoma affecting the female genital tract primarily or secondarily, which were classified on the basis of a widely accepted WHO classification. Although quite rare, our report should remind the pathologist of considering malignant lymphomas while reading biopsies taken from female genital organ.

Lymphoma of the female genital tract: current status

SUMMARY

: Primary lymphomas affecting the female reproductive system are uncommon but often pose a diagnostic challenge if their existence is not suspected. This article reviews the pathological and clinical features of lymphomas occurring in various sites in the female genital tract including the vulva, vagina, cervix, endometrium, fallopian tubes, and ovaries. Using the recent World Health Organization classification, the various types of lymphomas are identified as separate diseases and not as morphological variations of the same disease. The immunophenotypic and cytogenetics features of the major lymphomas are summarized. The incidence, presenting symptoms, gross and microscopic features, major differential diagnostic considerations, response to therapy, and expected outcome are discussed. Using published data on patient outcome, the International Federation of Obstetricians and Gynecologists and Ann Arbor staging systems are compared for their predictive value, and the difficulty in assigning primary and secondary status in extranodal lymphomas is emphasized. The observed differences in the behavior of some lymphomas in gynecological sites compared with their usual nodal location are presented. Finally, the possible etiology of these conditions is discussed in light of the emerging paradigm of mucosa-associated lymphoid tissue lymphomas.

Clinicopathologic features of six cases of primary cervical lymphoma

OBJECTIVE

Primary lymphoma of the uterine cervix is rare, with less than 60 cases reported. We present a series of 6 patients with cervical lymphoma and review the literature.

STUDY DESIGN

Between 1988 and 2003, we identified 6 women with primary lymphoma of the uterine cervix treated at our institutions. Data for analysis were obtained from hospital charts, office records, and tumor registry files. We also reviewed 20 published reports on cervical lymphoma, providing information on 58 additional patients.

RESULTS

The median age at diagnosis was 52 years (range 40-76). Three patients had an abnormal Papanicolaou test within 6 months of the diagnosis. Mean tumor size was 8.3 cm (range 3-14 cm). On the basis of the Ann Arbor system of staging where "E" denotes extranodal tumor origin, 2 patients had stage IE, 1 had stage IIIE, and 3 had stage IVE disease. The median follow-up for these 6 women was 33 months (range 12-120). Adding the 6 patients in our series to the 58 patients obtained from published reports, 43 had stage IE, 14 had stage IIE, 2 had stage IIIE, and 5 had stage IVE disease. There was no consistent pattern of treatment identified from our literature review.

CONCLUSION

Primary lymphoma of the uterine cervix is a rare malignancy. Most patients present with stage IE disease. Women with localized disease typically respond to various combinations of surgery, chemotherapy, and radiotherapy. Combination chemotherapy with tailored radiotherapy appears to be the preferred treatment option in women with advanced disease.

A case with multiple gynecological malignancies

A patient with cervical non-Hodgkin lymphoma was treated with chemotherapy. Fourteen months after the diagnosis of the lymphoma, an endometrial adenocarcinoma was detected as a secondary malignant tumor. The patient was treated with surgery followed by radiotherapy. Approximately 7 years after the diagnosis of endometrial cancer, vaginal invasive squamous cell carcinoma was diagnosed as the third primary malignancy, and a second-line palliative radiotherapy was applied. Seven months after the last radiotherapy, postradiational sarcoma in the vagina was diagnosed. Congenital and acquired immune system disorders, viral oncogenes, and various human leukocyte antigen (HLA) types were investigated. Total blood count and lymphocyte subset analysis were performed, and CD4+ lymphopenia was detected. Serologic tests were carried out for human immunodeficiency virus, hepatitis B virus, human papillomavirus, Epstein-Barr virus, and herpes simplex virus infection. Epstein-Barr virus viral capsid antigen IgG was found positive. Low-risk human papillomavirus panel was detected by Hybrid Capture method in the cervical smear. The HLA investigation revealed HLA-A2, HLA-A3, HLA-B57, HLA-B35, HLA-B4, HLA-B6, HLA-DR3, HLA-DR1, HLA-DR51, HLA-DR52, HLA-DQ6(1), and HLA-DQ7(3). The patient died because of the disease.

Primary stage I–IIE non-Hodgkin's lymphoma of uterine cervix and upper vagina: evidence for a conservative approach in a study on three patients

BACKGROUND

Non-Hodgkin's Lymphomas (NHL) frequently affect the uterine corpus, cervix, and vagina in cases of advanced disease. However, these organs are rarely the site of origin of this type of neoplasia. Because of the rarity of primary genital tract lymphomas, a standard treatment has not been defined.

CASE

Three patients with large B-cell primary Non-Hodgkin's lymphoma of the lower genital tract (vaginal, cervical and cervico-vaginal) presented with bulky lesions and underwent diagnostic evaluation, staging, and chemotherapy with adriamycin-containing regimens. All three patients, including two with stage IIE and one with stage IE disease demonstrated complete remission and are alive and well without evidence of disease at 10, 7, and 6 years of follow-up, respectively.

CONCLUSIONS

Our observations suggest that young patients with large B-cell lymphomas of lower genital tract stages I-IIE, even with bulky lesions, may benefit from chemotherapy alone as initial treatment.

Case report: appearance of uterine cervical lymphoma on MRI: a case report and review of the literature

We present the appearances on CT and MRI of a case of non-Hodgkin's lymphoma (NHL) of uterine cervix. A 41-year-old woman presented with a short history of urinary symptoms and menorrhagia. Previous cervical smears were normal. Clinically, the cervix was replaced by a huge ulcerating mass. Biopsy showed malignant high grade B-cell NHL. T(2) weighted MRI of the pelvis showed a 12 cm intermediate signal mass replacing the cervix, with infiltration of the vagina and left parametrium, and bilateral internal iliac lymphadenopathy. Whole body CT imaging showed lymphoma in the kidneys and pancreas, the latter associated with biliary obstruction. The patient is in complete remission 7 months post chemotherapy, radiotherapy and stenting of biliary stricture. The success of the cervical cancer screening programme has lead to a reduction in the number of cases of advanced cervical carcinoma and the presence of an unusually large homogeneous cervical tumour, with relatively scant necrosis should prompt suspicion of a less common histology such as NHL.

Primary B-cell lymphoma and lymphoma-like lesions of the uterine cervix

We present three patients with atypical lymphoid cells on cervical smear screening, with diffuse large-cell B-cell lymphoma diagnosed by morphology on cervical biopsy. One patient with extensive pelvic disease was treated with chemotherapy and radiotherapy and remained in remission 8 years later. Two patients with presumed stage 1E lesions showed spontaneous regression on repeat cervical biopsy, despite light chain restriction and clonal immunoglobulin gene rearrangement. They are without recurrent malignancy 1 and 5 years after their initial diagnosis. The presence of malignant looking lymphoid cells on cervical smear should be investigated by repeated colposcopic biopsies. The reason for the highly skewed atypical B-cell lymphoproliferation in lymphoma-like lesions of the cervix is unknown. With early stage, nonbulky cervical lymphoma in an otherwise healthy patient, a cone biopsy is advised. A number of these lesions may regress even when clonal populations are detected.

Primary non-Hodgkin's lymphoma of the uterine cervix successfully treated by neoadjuvant chemotherapy: case report

INTRODUCTION

Primary non-Hodgkin's lymphoma of the uterine cervix is a rare malignancy. The mainstay of therapy consists of irradiation alone or irradiation with either surgery or chemotherapy.

CASE REPORT

We present the case of a 56-year-old woman diagnosed with a bulky, Ann Arbor stage IE, primary, diffuse, large B-cell non Hodgkin's lymphoma of the uterine cervix. We administered neoadjuvant chemotherapy according to CHOP protocol (cyclophosphamide, adriamycin, vincristine, and prednisone) followed by radical hysterectomy, bilateral salpingo-oophorectomy, and regional lymph node dissection. Clinical and pathological responses to the chemotherapy were complete. The patient is alive 5 years after the initial diagnosis.

CONCLUSION

Our case emphasizes the importance of neoadjuvant chemotherapy that can provide a control of the distant microscopic metastases.

Non-Hodgkin lymphoma of the female genital tract. A five case series

Non-Hodgkin lymphoma (NHL) of the female genital tract is extremely rare. We report five cases of NHL, which were collected during an 8-year period from the files of the Department of Pathology at the Onze Lieve Vrouwe Gasthuis, Amsterdam. In these five cases, the NHL was clinically not considered and the genital location was the primary site of presentation.

[Non-Hodgkin's lymphoma of the uterus: apropos of 4 cases and review of the literature]

The primary non hodgkin's lymphoma of the uterus is rare. This rarity explains of one part certain difficulties of the histological diagnosis and on the other hand the absence of a therapeutic strategy clearly established. We report 4 cases of primary non-hodgkin lymphoma of the uterus. Two patients had a cervical location, the two other had corpus location. The average age of our patients is of 59 years (extremes: 54-68). Histological diagnosis was confirmed by biopsy for the cervical location. For the corpus location, it is study of the uterus after hysterectomy which retained the diagnosis of lymphoma. The type of the lymphoma was low grade in two cases and high grade in the two other cases. The disease was limited to the pelvis for all our patients (stage IE according to Ann-Arbor's classification). The treatment consisted of an association of chemotherapy and radiotherapy in both cases of lymphoma of the cervix and in a radical hysterectomy followed by chemotherapy for the two cases of lymphoma of the corpus. Our patients are regularly followed, with an average follow-up of 56 months. Two patients are in disease free, the third patient presented a dissemination of the disease and the fourth patient presented a squamous cell carcinoma of the lung.

Non-Hodgkin's lymphoma involving the gynecologic tract: a review of 88 cases

Non-Hodgkin's lymphoma (NHL) involving the gynecologic tract is unusual and may cause confusion for the pathologist not familiar with its clinical and histologic features. The literature regarding this topic is also confusing, as modern NHL classification systems were not used or patients were not staged according to the Ann Arbor system in many prior reports. In addition, immunophenotypic data is not available for many cases, particularly in older studies. In the past year, there has been an interest in NHL involving the gynecologic tract and 88 cases have been collected. These cases were reviewed in the Pathology Department of M.D. Anderson Cancer Center during the past two decades, and many of these patients were treated at this hospital. In this review, these cases are reported using updated terminology and almost all cases were immunophenotyped using immunohistochemical methods or flow cytometric methods in a small subset of cases. These cases have also been segregated into two groups: 1) localized NHL, that presumably initially arose in the gynecologic tract and therefore are primary; and 2) NHL that involved the gynecologic tract as a part of systemic disease, and therefore most likely represent secondary involvement of the gynecologic tract. The differential diagnosis of NHL involving gynecologic organs is discussed.

Synchronous occurrence of multiple malignant neoplasms in the uterus (adenocarcinoma of the endometrium, large B-cell lymphoma of the cervix)

Multiple primary malignancies of the uterus are extremely rare. We report a case of endometrial adenocarcinoma and cervical large B-cell lymphoma occurring simultaneously in a 64-year-old woman with uterine bleeding. Adenopathy, hepatosplenomegaly or bone marrow infiltration were not found. Both malignant neoplasms mentioned above were diagnosed incidentally on the specimen (total hysterectomy with bilateral salpingo-oophorectomy) removed for uterine leiomyomas.

Natural killer-cell lymphoma involving the gynecologic tract

Non-Hodgkin lymphomas (NHL) can involve the gynecologic tract, most often as a manifestation of systemic involvement, and most cases reported have been of B-cell lineage. We describe 2 women with natural killer (NK)-cell lymphoma involving the gynecologic tract that initially presented with vaginal bleeding. In case 1, the patient had a stage IE nasal-type NK-cell lymphoma involving the cervix. The tumor was composed of medium-sized, irregular lymphoid cells with angioinvasion and necrosis. In case 2, the patient had a stage IV blastoid NK-cell lymphoma/leukemia infiltrating all organs in a hysterectomy and bilateral salpingo-oophorectomy specimen. Subsequent biopsy specimens revealed that the bone marrow and lymph nodes were also involved. The neoplasm was composed of small to medium lymphoid cells with fine nuclear chromatin. Case 1 was assessed immunohistochemically and the neoplastic cells were positive for CD3, CD56, and TIA-1. Case 2 was analyzed using both immunohistochemical and flow cytometry methods. The neoplastic cells were positive for cytoplasmic CD3, CD4, CD7, CD43, CD45, and CD56 and were negative for surface CD3. Both cases were negative for Epstein-Barr virus (EBV) ribonucleic acid (RNA) and molecular studies showed no evidence of T-cell receptor gamma chain gene rearrangements. The immunophenotype and absence of T-cell receptor gene rearrangements support NK-cell origin. We report these cases to illustrate that NK-cell lymphomas can involve, and rarely arise in, the gynecologic tract.

Non-Hodgkin's lymphomas involving the uterus: a clinicopathologic analysis of 26 cases

Non-Hodgkin's lymphomas (NHL) involving the uterus may be either low-stage neoplasms that probably arise in the uterus (primary) or systemic neoplasms with secondary involvement. In this study, 26 NHL involving the uterus are reported. Ten cases were stage I(E) or II(E) and are presumed to be primary. The mean age of patients at presentation was 55 years (range, 35 to 67 years), and abnormal uterine bleeding was the most frequent complaint (six patients). Nine of 10 tumors involved the cervix. Histologically, eight were diffuse large B-cell lymphoma (DLBCL); one was follicle center lymphoma, follicular, grade 1; and one was marginal zone B-cell lymphoma. At 5 years of clinical follow-up, five of six patients were alive after treatment. In 12 cases, uterine involvement was part of a systemic disease at diagnosis, either stage III(E) or IV. The mean patient age at the time that uterine involvement was detected was 58 years (range, 22 to 75 years); 6 of 12 had abnormal uterine bleeding. Six tumors involved both cervix and corpus, four corpus, and two cervix. Six were DLBCL; two were small lymphocytic lymphoma; three were follicle center lymphoma, follicular, grade 1 (two cases) or grade 2 (one case); and one was precursor T-cell lymphoblastic lymphoma. At 5 years of clinical follow-up, two of seven patients were alive after treatment. Four DLBCL arose in patients with incomplete clinical information; therefore, stage is unknown. We conclude that low-stage (presumably primary) uterine NHL are most commonly DLBCL, predominantly arise in the cervix, and cause abnormal uterine bleeding. High-stage NHL are a heterogeneous group of B-cell neoplasms that can involve the cervix or the corpus.

Primary non Hodgkin's lymphoma of the vagina

The genital tract as a primary site of malignant lymphoma in women is extremely rare. This report concerns a 64 year old patient with a primary vaginal non-Hodgkin lymphoma (large cell B lineage according to the REAL classification--centroblastic type according to the Kiel classification--"G" according Working Formulation) with an unusual clinical presentation--pelvic discomfort accompanied by frequent ureteral-like colic. Due to gynecological onset symptoms and the rarity of this extranodal primary site misinterpretation of a primary vaginal lymphoma as a benign inflammatory disease or endometriosis may occur. We emphasize the importance of their recognition and also the differential diagnosis of cervical lymphoma from other neoplastic and non-neoplastic lesions.

Primary non-Hodgkin's lymphoma of the uterine cervix: case report of long-term survival of two patients treated with surgery and radiotherapy

Two patients with Stage 1EA primary non-Hodgkin's lymphoma of the uterine cervix were treated by surgery and radiotherapy in 1986 and 1987. On follow-up, over a period of 10 years, both are well and remain free of recurrence.

T-cell-rich B-cell lymphoma and Epstein-Barr virus infection of the uterus in a postmenopausal patient with an intrauterine contraceptive device in place for over 20 years

Although secondary involvement of the female genital tract occurs in up to 40% of cases of disseminated lymphomas, lymphomas presenting with primary female genital tract symptomatology are very unusual. We report a case of T-cell-rich B-cell lymphoma (TCRBCL) arising in the uterine corpus of a 57-year-old female who carried an intrauterine contraceptive device (IUD) for over 20 years. Malignant lymphoid cells expressed the Epstein-Barr virus (EBV) late membrane protein (LMP), a feature described in TCRBCL but not previously reported in primary uterine lymphomas. To our knowledge, this is the first reported case of a TCRBCL of the uterus.

Primary non-Hodgkin's lymphoma of the vagina. Case report and review of the literature

The genital tract as primary site of malignant non-Hodgkin's lymphoma in women is extremely rare, whereas secondary involvement in advanced disease is found in about 40% of cases. In this report a patient is presented who had a primary vaginal non-Hodgkin's lymphoma of the centroblastic type according to the Kiel classification, with an excellent response to cytotoxic chemotherapy (CHOP) and event-free disease for 3 years. A review of the literature shows that favorable prognosis of localized disease seems to be a common experience. Primary involvement of the vagina can be successfully treated by pelvic irradiation, but in young women cytotoxic chemotherapy should be considered to preserve fertility.

Treatment of patients with lymphomas of the uterus or cervix with combination chemotherapy and radiation therapy

BACKGROUND

Primary lymphomas of the uterus or cervix are so rare that treatment series of single institutions consist of very small numbers of patients, making standard treatment difficult to define. The outcome of patients treated with a combination of chemotherapy and radiation therapy was analyzed for all but patients with the most advanced disease.

METHODS

From 1976 to 1992, 16 patients received definitive treatment. Thirteen patients had intact uteri (group 1) and 3 presented with paracolpal lymphomas after previous hysterectomies (group 2). Twelve of the patients received chemotherapy and external irradiation. The remaining four underwent only chemotherapy. The overall survival and freedom from disease progression were analyzed according to Kaplan-Meier methods. Prognoses were related to the International Index, Ann Arbor stage, and International Federation of Gynecology and Obstetrics stage.

RESULTS

Five-year survival and freedom from disease progression were 77% and 67%, respectively, for group 1, and all patients in group 2 were cured. A statistically significant correlation of survival with scores of the International Index was found in group 1. For patients with scores in the low or low-intermediate range (n = 10), 5-year survival was 90%. All patients who scored in the high-intermediate or high range (n = 3) died by 66 months after their diagnosis (P = 0.0153). The Ann Arbor stage had less predictive value, with 5-year survival of 89% for Stage I and II patients (n = 9), compared with 50% survival for the four Stage III and IV patients (P = 0.0701). International Federation of Gynecology and Obstetrics staging did not predict outcome.

CONCLUSIONS

The combination of chemotherapy and irradiation is the most effective treatment regimen for all uterine and cervical lymphomas. The International Index is most predictive of outcome.
