Lymphoma of the female genital tract: current status

Vaginal involvement as a rare extranodal manifestation in advanced-stage follicular lymphoma: a case report and literature review

Apart from bone marrow involvement, extranodal involvement of follicular lymphoma (FL) is rare. Gynecologic FL is seldom reported, among which the vagina is the rarest involved site. No vaginal involvement in advanced-staged FL was reported before. Here, we report a case of FL with systemic involvement including the vagina.

Development and validation of nomograms to predict survival of primary cervical lymphoma: A surveillance, epidemiology, and end results (SEER) database analysis

Due to the rarity of primary cervical lymphoma (PCL), the long-term survival of patients with cervical lymphoma and factors influencing survival are unknown. This study aimed to compare the survivals of patients with PCL and those with other cervical tumors and construct a clinical prediction model to assess the prognosis of patients with PCL. Patients with PCL from the Surveillance, Epidemiology, and End Results database were allocated randomly in a 7:3 ratio to the training and validation sets. Cox proportional hazard and Fine-Gray models were used to verify independent factors influencing overall survival (OS) and disease-specific survival (DSS), and nomograms were constructed. Receiver operating characteristic curve analysis and decision curve analysis (DCA) were used to test the performance and clinical utility of the models, respectively. We included 206 patients with PCL. The areas under the curves (AUCs) and DCA showed that all models had clinical benefits; The models constructed in this study had a predictive performance for patients with PCL. It can guide clinicians to rationalize the treatment plan for patients.

Lymphomas of the Vulva: A Review of the MITO Rare Cancer Group

Since they are very rare tumors, lymphomas of the vulva are often not properly recognized. Patients with vulvar lymphoma are generally elderly and the classical manifestation of the disease is a vulvar mass. No significant age differences have been found between primary and secondary lymphoma. To make a correct diagnosis, it is therefore necessary to use not only histological examination but also the genetic and molecular profile in order to establish optimal therapeutic management. Literature analysis confirm the good prognosis of this disease.

Anaplastic large cell lymphoma presenting as a mass in the uterine cervix: a case report

T-cell lymphoma is an extremely rare form of malignancy in the female genital tract. Most of the reported cases of lymphoma are B-cell lymphomas. A few cases of primary T-cell lymphomas involving the vagina or the vulva have been reported. We are reporting the first case of anaplastic large cell lymphoma (ALCL) presenting as a uterine cervical mass. The patient is a 24-year-old female who presented to the emergency room with a history of menorrhagia, night sweats and 40-pound weight loss. The diagnosis of ALCL was confirmed through immunohistochemical studies with strong CD30 and ALK expression. Fluorescent hybridization showed a rearrangement of the anaplastic lymphoma kinase (ALK) gene. Since ALCL may have a variable expression of T-cell antigens, the diagnosis may easily be missed when CD45 and/or CD3 is negative, and screening epithelial stains for carcinoma (e.g., p63 and EMA) are positive. CD30 must be performed to raise the consideration of ALCL when reniform nuclei are observed.

Primary diffuse large B-cell tumor of the uterus: a case report

Primary diffuse large B-cell tumor of the uterus is a rare clinical condition with a similar clinical presentation to gynecologic tumors and is easily misdiagnosed. We report a case of a postmenopausal woman who presented with pelvic mass. Her ultrasound and MRI examinations suggested diffuse enlargement of the uterus, leading us to consider the diagnosis of lymphoma. The histological examination of the uterine mass confirmed the diagnosis of diffuse large B-cell lymphoma. The patient received 6 cycles of chemotherapy with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) and 2 cycles of consolidation therapy with R (rituximab). After treatment, the patient's uterus was significantly smaller than before and there was no sign of a recurrence.

Primary follicular lymphoma of the uterine cervix: A case report

Primary non-Hodgkin lymphoma of the uterine cervix is a rare clinical entity. The present case report describes an incidence of primary cervical follicular lymphoma, diagnosed during management of concurrent cervical intraepithelial neoplasia. The present case report outlines not only the necessity of adhering to guidelines regarding the management of abnormal cervical cytology, but also the importance of expert pathological review and the need for personalized management.

Primary Ovarian Non-Hodgkin's Lymphoma: An 18-year Retrospective Institutional Study and Review of Literature from India

BACKGROUND

Primary lymphomas of the female reproductive tract are rare and the ovarian extranodal presentation of non-Hodgkin's lymphoma (NHL) accounts for only 0.5% of all NHLs and 1.5% of all ovarian malignancies.

METHODS

We retrospectively reviewed the institutional medical oncology database for newly diagnosed NHL cases between 1999 and 2017. We aimed to study the clinical characteristics, pathology, and outcome of primary ovarian non-Hodgkin's lymphoma (NHL) cases presented to our institution.

RESULTS

We identified three patients (3.7% of extranodal NHLs and 0.85% of all NHL patients) with primary ovarian NHL from 350 NHL patient records. They underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy followed by six to eight cycles of (rituximab, adriamycin, cyclophosphamide, vincristine, prednisolone (R-CHOP/CHOP), and they attained complete remission.

CONCLUSION

Given the heterogeneity of cancer incidence in India and the absence of state-wise cancer registries, our study argues a pressing need to develop a national representative registry for NHL for accurate incidence, mortality, and survival data. Additionally, fertility preservation is an important issue that must be discussed with women of fertile age and the parents of children.

Manifestations of Ovarian Cancer in Relation to Other Pelvic Diseases by MRI

Imaging plays a pivotal role in the diagnostic approach of women with suspected ovarian cancer. MRI is widely used for preoperative characterization and risk stratification of adnexal masses. While epithelial ovarian cancer (EOC) has typical findings on MRI; there are several benign and malignant pelvic conditions that may mimic its appearance on imaging. Knowledge of the origin and imaging characteristics of a pelvic mass will help radiologists diagnose ovarian cancer promptly and accurately. Finally, in special subgroups, including adolescents and gravid population, the prevalence of various ovarian tumors differs from that of the general population and there are conditions which uniquely manifest during these periods of life.

Follicle Center Lymphoma (FCL) of the Lower Female Genital Tract (LFGT): A Novel Variant of Primary Cutaneous Follicle Center Lymphoma (PCFCL)

Primary cutaneous follicle center lymphoma has been distinguished from nodal follicular lymphoma (FL) based on genomic and clinical features. The nature of other extranodal FLs is not well defined. We report 15 cases of follicle center lymphoma involving the lower female genital tract. Cases were evaluated using an immunohistochemical panel for B-cell lymphoma, B-cell clonality, fluorescence in situ hybridization for BCL2 gene rearrangement, and next-generation sequencing. All patients had localized disease with no evidence of bone marrow involvement. Most cases (12/15, 80%) had a follicular pattern, at least focally. Large centrocytes were a prominent feature leading to concern for diffuse large B-cell lymphoma by referring pathologists. Neoplastic cells were positive for CD20 and BCL-6, while BCL-2 was positive in 2/15 (13%) cases. Fluorescence in situ hybridization for BCL2 gene rearrangement was negative in 10/11 (91%) cases. Next-generation sequencing performed in 10 cases revealed TNFRSF14 as the most frequently mutated gene in 6/10 (60%) cases. No case had CREBBP or KMT2D mutations as seen in nodal FL. None of the patients had progressive disease with durable complete remission achieved in 10/12 (83%) cases. The median follow-up period was 7.8 years (range: 0.2 to 20.5 y) with a 5-year overall survival of 100%. We conclude that follicle center lymphoma of the lower female genital tract is a novel variant of primary cutaneous follicle center lymphoma. Despite a frequent component of large cells, it is characterized by localized disease and low risk for dissemination. Awareness and recognition are important to distinguish these lesions from aggressive B-cell lymphomas.

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.

Non-Hodgkin's Vaginal Lymphoma: A Rare Presentation

Vaginal non-Hodgkin's lymphoma (NHL) is a rare entity. We report a case of a 38-year-old lady who presented with complaints of lower abdominal pain for three to four months and vaginal bleeding for one month. Her examination under general anesthesia revealed a hard vaginal mass which was biopsied and immunohistochemistry was performed. Diagnosis of diffuse B‑cell NHL (DLBCL) was made. Imaging plays an important role to reach the diagnosis. Chemotherapy is the treatment of choice.

Primary large B-cell lymphoma of the cervix: A case report and review of literature

The primary diffuse large B-cell lymphoma (DLBCL) of the uterine cervix is extremely rare. In the present study, we described two cases of DLBCL of the uterine cervix in reproductive-aged women complaining of postcoital bleeding, recurrent vaginal discharge, and abnormal uterine bleeding.

An Unusual Case of Chronic Lymphocytic Leukaemia Involving the Cervix

Chronic lymphocytic leukaemia (CLL) is a malignant monoclonal expansion of B lymphocytes, with accumulation of abnormal lymphocytes in the blood, bone marrow, spleen, lymph nodes and liver. It is mainly a disease of the elderly population. Though extra-nodal involvement is common, cervical and vulvovaginal involvement by CLL is particularly uncommon. In this case report, we discuss the case of cervical involvement of CLL in an 84-year-old patient who presented to rapid-access gynaecological clinic following concerns of persistent postmenopausal bleeding. Previously the patient was known to haematology with a well-controlled diagnosis of CLL since 2007. The initial examination was significant for an enlarged, irregular cervix, whereby a punch biopsy was then obtained. Histological analysis revealed evidence of CLL within the cervix.

Lobular Carcinoma of the Breast Metastatic to the Ovary: A Clinicopathologic Study of 38 Cases

We evaluated the clinicopathologic features of 38 cases of metastatic lobular (n=33) or predominantly lobular (n=5) carcinoma involving the ovary. The patients were from 39 to 91 years of age (mean: 53 y). In 2 cases, the breast primary and ovarian metastasis were diagnosed synchronously, and in 5, the breast primary was only discovered after the metastatic carcinoma in the ovary was found. In the majority of cases (79%), both ovaries were involved; the mean ovarian tumor size was 5.9 cm. The ovarian tumors demonstrated a range of architectural patterns including macronodular (71%), diffuse/solid growth (87%), single-cell infiltration (87%), cords (74%), and small nests/clusters (50%). Nine cases demonstrated focal signet ring cell morphology. The associated stromal reaction ranged from none to marked, with almost half of cases demonstrating a marked stromal response, largely prominent sclerosis. A variety of neoplasms, most typically sex cord-stromal tumors, lymphoma/leukemia, and desmoplastic small round cell tumor, may enter the differential. In addition to the obvious help afforded in most cases by the clinical history, a combination of judicious sampling, particularly to unearth the delicate cords or single-cell growth of lobular carcinoma, appropriate consideration of the cytologic features of the neoplastic cells, and immunohistochemistry can resolve the diverse issues in differential diagnosis that may arise.

Primary female genital system lymphoma complicated by a recurrent mucinous borderline ovarian tumor: a case report and review of the literature

Background

Primary female genital system lymphoma (PFGSL) is an infrequent entity. All genital organs may be affected, and most PFGSLs are localized to the cervix, uterine body, and ovaries. The clinical manifestations are nonspecific, which complicates a timely diagnosis. We report an unexpected case of PFGSL and discuss the disease characteristics by reviewing the literature.

Case presentation

A 48-year-old G3/P2 woman presented to the Department of Gynecology with a physical examination. Ultrasound examination and CT revealed pelvic masses. The woman underwent surgical treatment because of the pelvic masses and underwent a hysterectomy for a recurrent mucinous borderline ovarian tumor. However, the results of the postoperative pathological examination showed diffuse large B-cell lymphoma of the endometrium. After four courses of chemotherapy, the woman was in good condition. The clinical manifestations were nonspecific, which made a timely diagnosis complex.

Conclusion

This case highlights the importance of the difficulty in detecting early PFGSL early and how easily nonspecific manifestations can be ignored. It may lead to missing the best time for early treatment.

A rare case of metastatic uterine lymphoma in a renal transplant patient

Primary and disseminated lymphoma of the female reproductive tract are rare types of lymphoma. However, in the setting of solid organ transplant, recipients have an approximately doubled risk of acquiring and dying from malignancy. Multiple treatment modalities are available for post-transplant lymphoproliferative diseases (PTLD), including chemotherapy, radiotherapy, surgery, and immunosuppression radiotherapy. We report a case of a 61-year-old female with multifocal nodal diffuse large B-cell lymphoma and a history of a renal transplant secondary to IgA nephropathy who developed metastatic diffuse large B-cell lymphoma to the uterus. While the baseline incidence of PTLD is elevated when compared with lymphoma in the general population, metastatic uterine lymphoma is rare. Awareness of reproductive organ involvement by lymphomas and increased malignancy risk in organ transplant patients are important considerations for diagnostic evaluation, including radiologic assessment.

Primary diffuse large B-cell lymphoma of the uterus: A SEER database analysis

Uterine diffuse large B-cell lymphoma (DLBCL) is a rare clinical condition. Most studies for uterine DLBCL are derived from case reports and series. Our main objective was to present a new case while also investigating the demographic, clinical characteristics, and survival of women with primary uterine DLBCL as compared to non-uterine DLBCL using the Surveillance, Epidemiology, and End Results incidence database. We queried the Surveillance, Epidemiology, and End Results database for women aged 18 years or older with a diagnosis of primary DLBCL from 1975 to 2017. The most common site of primary uterine DLBCL is the cervix uteri not otherwise specified, followed by endometrium, uterus not otherwise specified, corpus uteri, myometrium and isthmus uteri. Non-uterine DLBCL cases tend to be older than uterine DLBCL cases. Uterine DLBCL is most common among women aged 40 to 64 years. Patients with uterine DLBCL showed greater survival than non-uterine DLBCL patients, and patients treated in the rituximab era also exhibited a survival benefit. Both the elderly and African American cohorts experienced worse overall survival.

Nonsquamous Lesions of the Vulvar Skin and Subcutaneous Tissue: A Review (Part 1)

OBJECTIVES

This article aimed to review "nonsquamous lesions of the vulvar skin and subcutaneous tissue" clinically and pathologically, based on the fifth edition of the World Health Organization tumor classification.

MATERIALS AND METHODS

A database search of PubMed and Google Scholar was performed between 1970 and 2021, using the search terms "vulva," "lower genital tract," and "nonsquamous lesions." The search was limited to "humans," "gynecopathology," and "dermatopathology." Full article texts were reviewed. Reference lists were screened for additional articles. We excluded articles written in the non-English language and abstracts.

RESULTS

A list of 600 articles was identified. Another screening identified 68 articles for clinicopathological features of nonsquamous lesions of the vulvar skin and subcutaneous tissue. In the first part of this review, we cover 5 major groups of nonsquamous lesions of the vulvar skin and subcutaneous tissue including (1) glandular tumors and cysts, (2) adenocarcinomas of other types, (3) germ cell tumors of the vulva, (4) neuroendocrine neoplasia, and (5) hematolymphoid hyperplasia and neoplasia. The rest of the major topics including mesenchymal tumors of the lower genital tract, melanocytic lesions, and metastasis will be discussed in the second part of this review.

CONCLUSIONS

Clinicopathological features of nonsquamous lesions of the vulvar skin and subcutaneous tissue as categorized by the updated World Health Organization classification are presented.

Primary diffuse large B-cell lymphoma of the fallopian tube treated with a combination of surgery and chemotherapy: Case report

RATIONALE

Primary female genital tract lymphomas are sporadic neoplasms, accounting for 0.2% to 1.1% of all cases of extranodal lymphoma. The most common genital localizations are the cervix, the uterine corpus and the ovary, while primary lymphomas of the fallopian tube are quite unusual. According to literature searching in PubMed, this is the first reported case of primary diffuse large B-cell lymphoma of the fallopian tube.

PATIENT CONCERNS

A 52-year-old woman presented with a more than 2 months history of intermittent lower abdominal pain. The gynecological examination showed that the uterus, as big as 3 months of pregnancy, had weak activity and no tenderness. The uterine rectum lacuna was like a hard nodule of about 3 × 2 cm, and an irregular solid mass was fixed and inactive in the right adnexa.

DIAGNOSES

In accordance with Ann Arbor staging system, a stage IE primary diffuse large B-cell lymphoma of fallopian tube was diagnosed for this patient, based on the tumor pathology, the results of bone marrow biopsy and computed tomography (CT) scan.

INTERVENTIONS

After gynecological/urinary ultrasound, blood test, pelvic contrast enhanced CT scan and CT angiography of iliac artery, exploratory laparoscopy and following hysterectomy with bilateral salpingo-oophorectomy were performed. After the surgery, the patient was treated with combined Rituximab and chemotherapy and got complete response (CR).

OUTCOMES

After the operation and R-CHPOP, following up for more than 1 year so far, the patient has no tumor recurrence and is still in good condition.

LESSONS

It is very difficult to diagnose the primary diffuse large B-cell lymphoma of fallopian tube, not only because of its rarity, but also because of its non-specific clinical manifestations. It easily be treated as late ovarian cancer by gynecologist. So the pathology diagnosis and surgeons' decision is very important. Because lymphoma is pretty sensitive to chemotherapy and easy to get complete response, so we no need to do an operation like ovarian cancer and should put chemotherapy as a primary method for lymphomas of the female genital tract.

Multimodality Imaging Approach to Ovarian Neoplasms with Pathologic Correlation

Ovarian neoplasms can be categorized on the basis of histopathologic features into epithelial surface cell tumors, germ cell tumors, sex cord-stromal tumors, and metastases. While their imaging appearance is often nonspecific, it closely parallels the gross pathologic appearance, and radiologic-pathologic correlation is helpful to aid in a deeper understanding of the subtypes. Epithelial cell neoplasms are the most common category, and they can be benign, borderline, or malignant. Specific subtypes include serous (most common), mucinous, seromucinous, endometrioid, clear cell, Brenner, and undifferentiated. High-grade serous cystadenocarcinoma accounts for the majority of malignant ovarian tumors and the most ovarian cancer deaths. While serous neoplasms are often unilocular and bilateral, mucinous neoplasms are larger, unilateral, and multilocular. Solid components, thickened septa, and papillary projections, particularly with vascularity, indicate borderline or malignant varieties. Endometrioid and clear cell carcinomas can arise within endometriomas. Fibrous tumors (cystadenofibroma, adenofibroma, fibroma or fibrothecoma, and Brenner tumors) demonstrate low T2-weighted signal intensity of their solid components, while teratomas contain lipid. The nonspecific imaging appearance of additional malignant ovarian germ cell tumors can be narrowed with tumor marker profiles. Sex cord-stromal tumors are often solid, and secondary signs from their hormonal secretion can be a clue to their diagnosis. The authors review the anatomy of the ovary and distal fallopian tube, the proposed origins of the histologic subtypes of tumors, the clinical features and epidemiology of ovarian neoplasms, and the applications of US, CT, and MRI in imaging ovarian neoplasms. The main focus is on the radiologic and pathologic features of the multiple ovarian neoplasm subtypes. An algorithmic approach to the diagnosis of ovarian neoplasms is presented. Online supplemental material is available for this article. ^©RSNA, 2020.

Primary B-Cell lymphoma of the uterine cervix presenting with right ureter hydronephrosis: A case report

Primary lymphoma of the uterine cervix is a very infrequent disease, usually affecting perimenopausal women. Symptoms are very similar to other gynecological malignancies, but treatment and prognosis completely differ, as most of these patients have a better survival. This condition has to be suspected in women with recent normal Pap smear test, rapidly growing tumor and initially non-contributory biopsies. We report a case of primary diffuse large-B-cell lymphoma of the uterine cervix mimicking a locally advanced cervical cancer with right ureter hydronephrosis at diagnosis. She was medically managed with a combination of rituximab and chemotherapy with cyclophosphamide, hydroxydaunorubicin, oncovin, and prednisone, associated to methotrexate for central nervous system prophylaxis. We will discuss about the role of combined treatments with surgery and radiotherapy, and the fertility sparing management in young women.

Endometrial sampling at an academic hospital in South Africa: Histological findings, lessons learnt and interesting surprises

Background

Outpatient sampling is used to investigate endometrial pathology. Little is known about practice habits and local failure rates at Chris Hani Baragwanath Academic Hospital in Johannesburg, South Africa.

Objective

This study assessed the frequency of samples that showed no or limited histological representation of endometrium, and described demographic and pathological features.

Methods

All endometrial sample histology reports from the National Health Laboratory Services at the hospital from 01 July 2013 to 31 May 2017 were retrieved by searching the laboratory’s information system. Clinical variables (age, menopausal state, indication for biopsy, endometrial thickness on ultrasound) and pathological findings (macroscopic amount of tissue, histological diagnosis, microscopic presence of endometrial tissue) were extracted and statistically analysed.

Results

A total of 1926 samples were included, 91% of which were submitted for abnormal or postmenopausal bleeding. No endometrium was observed in 25% of samples and 13% showed limited endometrium. Benign diagnoses (86%) were most common, with proliferative or secretory changes, endometrial polyps and endometritis accounting for most of these. Associations between the amount of sample received and the presence of endometrial tissue (p ≤ 0.001) and benign versus malignant diagnoses (p ≤ 0.001) were noted. The greater the endometrial thickness, the greater the likelihood of obtaining more sample (bulky vs scant p < 0.001) and making a malignant versus benign diagnosis (p = 0.005).

Conclusion

These findings are in keeping with literature outside Africa. Histology reports should be explicit when terms such as ‘inadequate’ or ‘insufficient’ are used, in order to facilitate clinical decision-making.

Extramedullary Leukemia, Presenting at the Cervix of the Uterus

Extramedullary relapse of leukemia is encountered more often than in the past. The reason is that leukemia survival rates increase with improved treatment schemes. We present a rare case of involvement of the cervix of the uterus in an adult B Acute Lymphocytic Leukemia (B-ALL) survivor. Relapses affect various organs but rarely the female genital tract. Nevertheless, in this case, a woman with a history of induced amenorrhea due to treatment for leukemia presented to the gynecologist because of vaginal spotting. Colposcopy evaluation of the vagina/cervix, sonography and cytological and histological sampling established the diagnosis of leukemia relapse in the cervix of the uterus. Under these circumstances, our study highlights the rare extramedullary presentation of leukemia in the cervix of the uterus of a young lady considered to be disease-free and listed for bone marrow transplantation. In this rare case of relapse in the cervix of the uterus, Pap smears alarmed physicians, and radiology examinations assisted the diagnostic workup. Still, only biopsy, microscopic evaluation, and immunohistochemistry studies established the exact diagnosis. Prognosis in the situation of extramedullary disease relapse in the female genital tract was poor, but gynecologists' high suspicion led to a prompt diagnosis. Survival is in general limited, but together with high suspicion, multidisciplinary team involvement is imperative to improve the reduced chances of survival.

Diagnosis and management of vulvar cancer: A review

Vulvar malignancies represent a serious gynecologic health concern, especially given the increasing incidence over the past several decades. Squamous cell carcinoma and melanoma are common subtypes, although other neoplasms, such as basal cell carcinoma and Paget disease of the vulva, might be seen. Many vulvar cancers are initially misdiagnosed as inflammatory conditions, delaying diagnosis and worsening prognosis. It is essential that dermatologists are familiar with characteristic findings for each malignancy to ensure appropriate diagnosis and management. Herein, we review the unique epidemiologic and clinical characteristics of each major vulvar malignancy, as well as discuss their respective prognoses and current management recommendations.

Primary Vaginal Non-Hodgkin Lymphoma

Non-Hodgkin lymphoma (NHL) is a type of blood cancer and 25% of NHL patients present with a primary extranodal tumor. Primary NHL of the vagina is extremely rare with only a few cases reported. We present the case of a 79-year-old, grand multipara, Peruvian woman with an eleven-month history of symptoms of pelvic and vaginal pain and vaginal bleeding. Vaginal examination revealed an exophytic tumor that involved the labia, right vaginal wall, cervix, parametrium, and pelvic bone. A computed tomography (CT) image showed a 10 x 10 x 9-cm solid tumor in the pelvic cavity with irregular edges in the pelvic floor, parametrium, and the perineal soft tissues. Bilateral pelvic and inguinal adenomegalies were found. No signs of metastases were found. Marrow and bone biopsy studies were negative. The diagnosis was NHL type diffuse large B-cell lymphoma (DLBCL) of vagina stage one. The patient was treated with six courses of CHOP-R (cyclophosphamide, doxorubicin, vincristine, prednisone, and rituximab). She showed a complete response and remained in remission in follow-up control visits. NHL of the female genital tract is rare. CHOP-R is the first line of treatment for this type of cancer. However, less is known about the follow-up protocol and relapse management. Vaginal lymphoma has an extremely low prevalence, and collaborative studies are required to study the same.

Primary uterine lymphoma: The Yokohama Cooperative Study Group for Hematology (YACHT) study

AIM

Primary malignant lymphomas arising from the female genital tract are very rare, with an incidence rate of 0.5%. Because of its rarity, its clinical characteristics, prognosis and optimal treatment are still unclear. Here, we retrospectively evaluated female patients with uterine lymphoma.

METHODS

Between January 2000 and October 2016, 4362 patients were newly diagnosed with malignant lymphoma by the participating institutions of YACHT. Among these 4362 patients, we retrospectively evaluated 14 adult patients with primary uterine lymphoma.

RESULTS

The median follow up time was 41 months. The median age at diagnosis was 68 years. Of 14 patients, 10 (72%) were diagnosed with diffuse large B-cell lymphoma. Seven patients presented with vaginal bleeding and three with abdominal pain. Eleven patients (79%) had advanced stages at diagnosis. Three patients (21%) had ovarian involvement and 2 (14%) had vaginal involvement. Induction chemotherapy regimens were R-CHOP in seven patients (50%), CHOP in three (21%) and other regimens in four (29%). Among 14 patients, 12 patients (86%) achieved a complete response and 2 (14%) experienced disease progression. Three patients (21%) showed relapse. Five patients (36%) died because of malignant lymphoma. The 3-year overall survival rate was 57.9%. Soluble interleukin-2 receptor levels > 5000 U/mL, anemia, a bulky mass and the presence of > 1 extranodal sites, B symptom at diagnosis were associated with a poor prognosis.

CONCLUSION

Female genital lymphoma is very rare, and further study of more cases is warranted.

Malignant lymphoma of the uterine cervix presumptively diagnosed by Pap smear: A case report

Malignant lymphoma of the uterine cervix is exceedingly rare and is difficult to diagnose by cervical cytology. The current study presents a case of malignant lymphoma of the uterine cervix that was presumptively diagnosed by cervical cancer screening in which the patient had no clinical symptoms. The anterior lip of the uterine cervix was occupied by a macroscopic hemorrhagic tumor. The obtained tumor cells exhibited typical cytological features of malignant lymphoma and were positive for CD20. The final diagnosis was diffuse large B cell lymphoma of the uterine cervix, stage IIEA (Ann Arbor classification). The patient received 6 courses of R-CHOP chemotherapy and achieved complete remission. Despite its rarity, the possibility of malignant lymphoma should be considered while screening for cervical cancers using Pap smears. The Pap test screening may be useful for the early diagnosis of malignant lymphoma of the uterine cervix in certain cases. By reaching a rapid and accurate diagnosis, immediate treatment may be initiated and surgery may be avoided.

A Case of Primary Uterina Lymphoma Presenting with Bleeding, Pelvic Pain, and Dysmenorrhea

Primary non-Hodgkin's lymphoma (NHL) can arise from lymphatic cells located in solid organs (extranodal) and it accounts for 25 to 35% of all NHL. Primary lymphoma on the female genital tract (PLFGT) is a rare disease, comprising 0.2 to 1.1% of all extranodal lymphomas in the female population. In this paper, the authors report an extremely rare case of a 48-year-old woman who exhibited an abnormal uterine bleeding, pelvic pain, and dysmenorrhea history. The transvaginal ultrasound showed an anteverted uterus measuring 153 cm³ in volume, with intramural leiomyomas. She underwent a total laparoscopic hysterectomy with bilateral salpingectomy. The histologic evaluation of the specimen showed a follicular lymphoma with diffuse pattern in the endometrium. This report illustrates the difficulty in the diagnosis of primary lymphomas of the female genital tract.

Primary non-Hodgkin's lymphoma of the vagina: A case report

Primary non-Hodgkin's lymphoma (NHL) of the vagina is uncommon. The present case study reports the case of a 54-year-old female with a palpable mass between the rectum and vagina. The patient presented with symptoms consistent with vaginal cancer but lacked any of the ‘B’ symptoms often associated with systemic lymphoma, including fever, weight loss, night sweats and fatigue. The mass was resected under anesthesia. Immunohistochemistry and biopsy confirmed diffuse large B-cell NHL (DLBCL). Following surgery, six cycles of chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone were administered. Subsequently, a vertebral body metastasis was observed using a computed tomography scan and whole-body bone imaging. The patient received palliative radiation for the vertebral body metastasis. Additionally, the available literature was reviewed in order to further characterize this rare disease.

Epstein-Barr virus positive diffuse large B-cell lymphoma presenting with vaginal sloughing and ulcerated skin nodule

Malignant lymphomas presenting in the female genital tract are extremely rare. We report a case of Epstein-Barr virus associated diffuse large B-cell lymphoma of the genital tract and skin in a 60-year-old woman on long-term azathioprine.

Primary lymphoma of the female genital tract: An analysis of 697 cases

OBJECTIVE

Primary lymphoma of the female genital tract (PLFGT) is a rare entity. The aim of this population-based study was to elucidate the clinico-pathological, demographic characteristics and survival of women with PLFGT.

MATERIALS AND METHODS

The Surveillance, Epidemiology, and End Results database was accessed and cases of PLFGT diagnosed between 1988 and 2012 were identified. Five-year overall (OS) and cancer-specific (CSS) survival rates were calculated with the Kaplan-Meier method. The influence of demographic and clinical parameters on survival was examined with the log-rank test. Factors independently associated with cancer-specific mortality were evaluated with a Cox proportional hazard model.

RESULTS

A total of 697 women with PLFGT were identified with a median age of 54years. The most prevalent histological subtypes were diffuse large B-cell (59.8%) and follicular (11.9%) lymphoma. Tumors were most commonly located in the ovary (37%), cervix (21.4%), and uterus (16.5%). According to the Ann Arbor staging system, 42.6% and 17.9% of cases had stage I and stage II disease, respectively. Cancer-directed surgery (CDS) was performed in the majority of cases (62.8%). Five-year OS and CSS were 70.2% and 75.2% respectively. Localized disease, premenopausal age and follicular histology were associated with superior cancer-specific mortality while CDS did not confer any mortality benefit.

CONCLUSIONS

This is the largest cohort of PLFGT presented in literature. While in our study surgical treatment was not associated with improved outcomes, larger multi-institutional studies should address the optimal management of women with PLFGT.

18F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography Scan in an Unusual Case of Lymphoma with Secondary Involvement of Uterine Cervix Presenting as a Pathological Fracture

A 48-year-old female presented with a pathological fracture of the right femur. ^99mTc methylene diphosphonate bone scan revealed multiple areas of increased osteoblastic activity consistent with metastatic disease. Serum electrophoresis revealed monoclonal gammopathy. ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (¹⁸F-FDG PET/CT) scan revealed metabolically active lesions in bulky uterine cervix and osteolytic skeletal lesions. Unusual pattern of FDG uptake in uterine cervix and osteolytic skeletal lesions warranted a biopsy of the uterine cervix which revealed diffuse large B-cell lymphoma. ¹⁸F-FDG PET/CT scan helped in guiding the site of biopsy to reach a final diagnosis in this unusual case of lymphoma with a secondary involvement of uterine cervix presenting as a pathological fracture.

Imaging of Extranodal Genitourinary Lymphoma

The genitourinary (GU) system is commonly affected by disseminated lymphoma. Rarely, lymphoma can originate from and remain localized to one of the GU organs and thus presents as primary extranodal disease. Up to 40% of lymphomas present as extranodal disease, with only 3% having the GU system as the primary site of involvement. This article describes and correlates the radiologic and pathologic features of extranodal lymphomatous disease affecting the GU system with specific focus on the kidneys, adrenal glands, testicles, and ovaries. Lymphoma of the uterine body and cervix, external female genitalia, urinary bladder, and prostate gland is briefly discussed.

Primary B-cell lymphoma of the uterine cervix: Presentation in Pap-test slide and cervical biopsy

This case involved a 69-year-old female who presented with irritative urinary voiding. Imaging studies showed an 18-cm uterine mass centering on the cervix and extending into the bladder. The Pap test slide demonstrated necrotic background and degenerative changes in single and grouped atypical "small round blue cells" with high nuclear/cytoplasm ratio, scant cytoplasm, and hyperchromatic focally cleaved nuclei with occasional nuclear membrane "snout projections." Cervical biopsies showed similar findings. The tumor cells were positive for CD45, CD20, and PAX-5, and negative with epithelial, neuroendocrine, and muscle markers. A Ki-67 immunostain showed a markedly elevated proliferative index and the MUM1 stain was diffusely positive. Molecular study identified clonal immunoglobulin heavy chain gene rearrangement. Owing to its rarity, cervical lymphoma may sometimes be confused with other types of malignant neoplasms or inflammatory processes. Therefore, it is important to recognize the cytological features of cervical lymphomas and be aware of the potential diagnostic pitfalls for timely diagnosis and therapy. Diagn.

Molecular targeted therapy in gynaecologic malignancies: primer for radiologists

The identification of characteristic genetic alteration in gynaecological malignancies has opened the door for molecular targeted therapy. The purpose of this review is to provide a primer for the radiologist on these agents with emphasis on the role of imaging in treatment response assessment and drug toxicities. The use of targeted therapy in gynaecological malignancies will likely increase in the future and make the role of the radiologist critical in response assessment and detection of toxicities.

Primary Non-Hodgkin's Lymphoma of the Vulva: A Case Report and Literature Review

The aim of this study was to add a new case of primary non-Hodgkin's malignant lymphoma of the vulva to the literature and to review the current literature.We searched the PubMed/MEDLINE databases for previous case reports using the key words "non-Hodgkin's malignant lymphoma of the vulva," "vulvar lymphoma," and "primary vulvar non-Hodgkin's lymphoma." We found 29 cases of primary vulvar non-Hodgkin's malignant lymphoma of the vulva reported until 2015. Among them, only 8 cases of diffuse large B-cell lymphoma (DLBCL), classified according to the most recent 2008 WHO classification, were reported.Moreover, only few studies reported the therapeutic management and clinical follow-up of patients affected by this condition.Due to its uncommon presentation, the primary non-Hodgkin's malignant lymphoma of the vulva can be undiagnosed; thus gynecologists, oncologists, and pathologists should be aware of this condition, as a correct diagnosis is essential for an appropriate therapeutic management.

Primary Vaginal Non-Hodgkin's Lymphoma: Report of a Rare Clinical Entity

A 52-year-old woman was referred to the gynecology outpatient clinic with a 2 months history of vaginal bleeding with intercourse, and no other symptoms. Vaginal examination revealed a firm, non-tender, mass in the posterior vaginal wall. The initial clinical impression was that of a vaginal carcinoma and a biopsy under local anesthesia was performed, but the result was inconclusive. A deeper biopsy, under general anesthesia, was performed and a histological diagnosis of non-Hodgkin’s lymphoma was done. The staging workup permitted to exclude any other site of the body affected by the malignancy. Hematologists reviewed the patient and recommended chemotherapy. A complete tumor regression was observed and the patient has now a disease-free survival of 72 months. This case report intends to create awareness of this rare clinical entity. Although the gynecologist will rarely be faced to extranodal lymphoma, it should be included in the differential diagnosis of gynecologic malignancies.

Primary T-Cell Non-Hodgkin Lymphoma of the Vagina

The primary vaginal T-cell non-Hodgkin lymphoma is a rare form of lymphoma. Most of the previously published cases were about B-cell non-Hodgkin lymphomas. We present the case of a vaginal mass in an 82-year-old patient presenting vaginal bleeding. The results of the immunohistological studies of the mass revealed the presence of a cytotoxic T-cell non-Hodgkin lymphoma, which is the least common subtype.

Incidentally discovered diffuse large B-cell lymphoma limited to the endocervical mucosa in a young female patient

Primary high-grade non-Hodgkin lymphoma of the female genital tract is extremely rare. Vaginal bleeding, abdominal pain or urinary complaints might be its most frequent symptoms. We report a 27-year-old multipara who underwent large loop excision of the transformation zone because of the repeated finding of a low-grade squamous intraepithelial lesion identified during routine cancer screening. Incidentally, CD20-positive, primary, diffuse large B-cell lymphoma infiltrating the mucosa of the endocervix was also diagnosed from this specimen. The case is unusual because the patient had no symptoms, specific colposcopic signs or visible mass. R-CHOP 21 immunochemotherapy was introduced and resulted in complete remission without hysterectomy. The patient is without any evidence of disease after 49 months of follow-up. Primary cervical lymphomas are mainly subepithelial initially, and therefore they may be under-recognized due to the inefficiency of smears to diagnose such lesions. Early diagnosis and available targeted treatment allowed a cure in the reported example.

Primary nodular lymphocyte-predominant Hodgkin lymphoma of uterine cervix mimicking leiomyoma

Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) accounts for about 5% of all Hodgkin lymphomas and predominantly involves peripheral lymph nodes. Primary NLPHL of uterine cervix is very rare. Here, we report cervical NLPHL with CD21 expression in a 43-year-old woman, who presented with abnormal vaginal bleeding for 1 year.

Institutional review of primary non-hodgkin lymphoma of the female genital tract: a 33-year experience

OBJECTIVE

The aim of this is to provide an updated review of the literature and to report our institutional experience with this rare gynecologic malignancy.

METHODS

The medical records of patients with diagnosis of non-Hodgkin lymphoma of the female genital tract from 1980 to 2013 at the Yale-New Haven Hospital were reviewed retrospectively. Histological classification and staging were determined by the World Health Organization and Ann Arbor systems, respectively. Kaplan-Meier was used to calculate the survival.

RESULTS

There were 36 patients with diagnosis of non-Hodgkin lymphoma of the female genital tract and followed for a median of 61 months (0-361 months). The median age of diagnosis was 44 years (19-87 years), and 76% (n = 28) were classified as stage IV.Of these, 4 patients were asymptomatic on presentation, and 13 were identified incidentally during surgery/radiography (n = 9), on prenatal ultrasound (n = 1), and on Papanicolaou test (n = 3). The location of the disease included the ovary (n = 6), uterine corpus and cervix (n= 9), vagina (n = 1), a pelvic mass (n = 7), isolated pelvic/para-aortic lymph nodes (n = 3), and/or multiple sites (n = 9). There were 6 cases that were concomitant with other gynecologic malignancies.Diffuse large B-cell lymphoma (n= 18) was the most common histologic type. A total of 28 patients underwent surgery. Combination chemotherapy was used in 34 patients, with concomitant radiation therapy in 7 and stem cell transplantation in 3. A total of 5 patients had recurrent disease.The overall median survival from the diagnosis of lymphoma was 70 months (0.3-361 months) with a 91% 1-year survival, 86% 5-year survival, and a 79% 10-year survival.

CONCLUSIONS

Our report is the largest published single-institution experience of this disease. It demonstrates a more favorable prognosis and proposes that with early diagnosis and appropriate therapy, radical gynecologic surgery can be avoided.
