Clinical, Pathological and Immunohistochemical Characteristics of Patients with Primary Testicular Lymphoma Undergoing Orchiectomy: A Systematic Review and Meta-Analysis.

BACKGROUND: Primary testicular lymphoma (PTL) is a rare and aggressive malignant tumour with no specific clinical symptoms. Large-scale evidence-based medical evidence to guide preoperative diagnosis is lacking at present. This study aimed to analyse the clinical, pathological and immunohistochemical characteristics of patients with PTL undergoing testicular resection surgery. METHODS: Literature on the clinical characteristics of patients with PTL undergoing orchiectomy was retrieved from databases, including PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI) and Wanfang Data. The search covered all available records from the inception of these databases until December 31, 2023. Data extraction was followed by a meta-analysis using Stata 15.0 software. RESULTS: A total of 22 articles and 475 cases of PTL were included. The meta-analysis revealed that 58.1% of patients with PTL undergoing orchiectomy were under 60 years old, and 41.9% were 60 years or older. The lesion is mostly located on the right side (55.1%). Common symptoms included testicular swelling and falling swelling (91.3%), hydrocele testis (31.0%) and testicular pain (23.0%). Ann Arbor stages I-IV accounted for 53.3%, 16.7%, 14.8% and 15.7%, respectively. Diffuse large B-cell lymphoma (DLBCL) cases were higher at 95.5% than NK/T-cell lymphoma cases at 8.2%. Amongst DLBCL cases, 69.3% were non-germinal centre B-cell (GCB) subtype, and 27.6% were GCB subtype. Immunohistochemistry markers showed 95.9% CD3 negative, 94.9% CD10 negative, 94.4% CD20 positive, 88.4% multiple myeloma oncogene-1 (MUM-1) negative, 73.6% B-cell lymphoma-6 (BCL-6) negative and 66.5% BCL-2 positive. Laboratory findings indicated that 70.4% of patients had a tumour proliferating cell nuclear antigen (Ki67) index of ≥80%, 36.0% had increased serum lactate dehydrogenase level and 22.9% had increased serum ß2-microglobulin level. CONCLUSIONS: PTL is rare, and it often occurs in elderly male patients. Common symptoms include testicular swelling and falling swelling, and the common histological type is DLBCL. Diagnosis should be based on histopathological characteristics and immunohistochemical examination.

Acute global testicular infarction: A rare and important complication after endovascular abdominal aortic aneurysm repair.

Testicular ischemia is one of the most rarely reported complications of endovascular abdominal aortic aneurysm repair (EVAR). Although the pathogenesis remains unclear, thromboembolic events in the setting of testicular artery origin occlusion by the stent graft and poor baseline collateral testicular circulation are presumed causes. A 73-year-old man developed acute right testicular infarction 3 days after EVAR, requiring orchiectomy. This case emphasizes the importance of recognizing and evaluating testicular pain after EVAR and counseling patients on this possible EVAR complication.

Bilateral Synchronous Testicular Cancer with Discordant Histopathology: A Case Report.

Bilateral testicular tumors account for 1 to 5% of all testicular tumors. Most bilateral tumors are observed metachronously. Synchronous tumors usually present with the similar histological pattern. Bilateral synchronous testicular tumors with discordant pathology are extremely rare. Only 56 cases have been documented since Bidard first described synchronous testicular tumors with discordant pathology in 1853. To our best knowledge, this study will be the 57th case in the literature.

Ascending colon cancer metastasized to the right testicle: a case report.

BACKGROUND: Testicular metastasis from malignant solid tumors is extremely rare. It is usually found by chance during autopsy or pathological examination of testicular specimens. Therefore, we consider it necessary to report our patient's case of testicular metastasis from colon cancer. CASE PRESENTATION: We report a 61-year-old Han Chinese male patient who presented to our clinic with progressive painless swelling of the right testicle for 2 years. Positron emission tomography-computed tomography scans showed increased 18F-fluorodeoxyglucose metabolism in the right testicle, possibly owing to distant metastasis. His previous medical history suggested that he had undergone laparoscopic-assisted right hemicolectomy for ascending colon cancer 4 years ago. Considering the ascending colon cancer metastasis to the right testicle, we performed a right radical testicular resection through an inguinal approach. Postoperative histological examination showed intestinal metastatic adenocarcinoma. CONCLUSION: Colon cancer metastasis to the testes is uncommon. The clinical and imaging manifestations of this tumor are nonspecific, so the diagnosis relies on postoperative pathology. If testicular metastasis is found, treatment principles for advanced colon cancer should be followed.

Supernumerary testis or polyorchidism: A rare urogenital anomaly (case report and literature review).

INTRODUCTION AND IMPORTANCE: Polyorchidism, or supernumerary testis, is a rare urogenital congenital disorder. Because of its rarity, there is no approved standard treatment protocol for preserving or removing the extra testicle, yet orchiopexy is frequently performed as a preferred treatment in most medical facilities. CASE PRESENTATION: We present a 23-year-old single male with a bilaterally empty scrotum. He was unaware of his condition and had not seen a doctor before being admitted to our surgical unit. During his younger sibling's circumcision by a local circumcisionist (a medical staff member, idealy a nurse, whose duty is to perform circumcision, preferably at home), he saw something different (his emptey scrotum) and came to us with his problem. Laboratory findings revealed severe oligospermia, and tumor markers (Alpha fetoprotein, beta-human chorionic gonadotropin, and lactate dehydrogenase) were negative for malignancy. The patient underwent bilateral herniorrhaphy and orchiopexy of all six testicles (three in each inguinal canal) and had an uneventful recovery. CLINICAL DISCUSSION: As polyorchidism is not a common problem, its management remains a contentious issue due to the lack of evidence-based consensus. However, with the introduction of new imaging modalities and on-table frozen section biopsy, the decision to continue with orchiopexy or orchiectomy can be easily justified; however, conservative treatment is preferable in cases of no coexisting anomalies, particularly cryptorchidism. CONCLUSION: Polyorchidism could run unnoticed for years, especially if there is no direct and consistent access to a medical facility. In cases where polyorchidism is detected accidentally by imaging or during surgical exploration, the treatment must be justified accordingly.

Identification and Management of Testicular Mesothelioma Identified Intraoperatively: A Case Series.

Testicular mesothelioma lacks the characteristic presentation of testicular malignancy and often has normal biomarkers at the time of diagnosis causing this malignancy to be overlooked and diagnosed intraoperatively during elective scrotal surgery. We present two cases of testicular mesothelioma that were diagnosed incidentally during hydrocelectomy. These cases emphasize the importance of considering testicular mesothelioma during hydrocele and scrotal mass workup and demonstrate the need for standardized guidelines for the management of testicular mesothelioma.

Owner survey suggests cats may be undertreated for pain compared to dogs after an elective ovariohysterectomy or orchiectomy.

OBJECTIVE: To investigate differences in pain management between dogs and cats after surgical sterilization. We hypothesized that dogs would be more likely to be discharged with analgesics after sterilization compared to cats and that owner compliance would be better in dogs. ANIMALS: 175 respondents owning 92 dogs and 83 cats from a high-volume, low-cost veterinary clinic in Michigan during August 2022. METHODS: Owners received an online survey designed to assess their pet's postoperative analgesic care. They were asked demographic information about themselves and their pets. Additionally, they were asked if their pet was discharged with analgesics, if they were administered as prescribed, and if their pet was painful at home. Dogs and cats were included if they were sterilized within 6 months of survey completion and in the owner's care at the time of the procedure. RESULTS: The survey was distributed to 5,241 owners and received 227 responses, a response rate of 4.4%. Analgesics were prescribed for 19 of 162 (12%) pets: 14 of 88 (16%) dogs and 5 of 74 (6.7%) cats. There was no difference in the prescription of analgesics between dogs and cats after ovariohysterectomy (P = .09) or orchiectomy (P = .73). 15 of 19 owners reported their compliance in administering analgesics at 78.9%. Owners' subjective assessments showed that 24 of 86 (28%) dogs and 12 of 68 (17%) cats appeared painful at home. CLINICAL RELEVANCE: Postoperative pain in cats may not be appropriately managed.

The impact of health care on outcomes of suspected testicular torsion: results from the GRAND study.

BACKGROUND: Suspicion of testicular torsion represents a urological emergency, necessitating immediate surgery. Comprehensive data on the current trends and perioperative outcomes regarding surgical exploration are sparse. Therefore, we utilized nationwide data on the prevalence and results of this surgery, aiming to provide evidence on this matter. METHODS: We assessed the GeRmAn Nationwide inpatient Data (GRAND) from 2005 to 2021, provided by the Research Data Center of the Federal Bureau of Statistics. We performed multiple regression analyses to evaluate the perioperative outcomes (length of hospital stay, transfusion, and surgical wound infection) after surgical exploration due to suspected testicular torsion based on both the outcome of surgery (orchiectomy, detorsion with preservation of the testicle, and no testicular torsion) and on the department of operation (urological versus non-urological). RESULTS: A total of 81,899 males underwent surgical exploration due to suspected testicular torsion in Germany from 2005 to 2021. Of them, 11,725 (14%) underwent orchiectomy, 30,765 (38%) detorsion with preservation of the testicle and subsequent orchidopexy, and 39,409 (48%) presented no testicular torsion. Orchiectomy was significantly associated with longer length of hospital stay (day difference of 1.4 days, 95%CI: 1.3-1.4, p < 0.001), higher odds of transfusion (1.8, 95% CI: 1.2-2.6, p = 0.002) and surgical wound infections (1.8, 95%CI: 1.4-2.3, p < 0.001) compared to no testicular torsion. The proportion of patients undergoing orchiectomy was significantly lower in urological departments (14%) versus non-urological departments (16%) and the proportion of patients undergoing preservation of testicle after detorsion was significantly higher in urological departments (38%) versus non-urological departments (37%), p < 0.001. Patients undergoing treatment in a urological department were discharged earlier and presented lower odds of transfusion and surgical wound infection (p < 0.001) compared to patients undergoing treatment in a non-urological department. CONCLUSIONS: Nearly half of patients who underwent surgery for suspected testicular torsion did not have intraoperatively the condition confirmed. Patients treated in urological departments had significantly better perioperative outcomes compared to those treated in non-urological departments. Therefore, we advise to refer patients to urological treatment as early as possible.

Idiopathic granulomatous orchitis: A case study.

Idiopathic granulomatous orchitis (IGO) is a rare inflammatory disorder of unknown etiology affecting the testis. Presented here is the case of a young patient who developed IGO, potentially associated with an anti-sperm antibody-mediated autoimmune response.

A Rare Case of a Non-seminomatous Testicular Cancer Metastasis to the Duodenum: A Case Report.

Testicular cancer is among the most common solid tumors in young men. Gastrointestinal tract (GIT) metastasis of testicular cancer has been rarely reported. In addition, metastasis occurs most commonly through retroperitoneal lymph nodes. Manifestations like abdominal pain and obstruction can be present if metastasis to GIT was considered. We report here a case of a 34-year-old male who was admitted to our GIT unit complaining of episodic epigastric pain. Computed Tomogram (CT) scan demonstrated a soft tissue like lesion involving the lumen of duodenum. Moreover, the patient had a right radical orchiectomy 18 months prior to the presentation due to a stage IA non-seminomatous germ cell tumor with no lymphovascular invasion and free surgical margins. Esophagogastroduodenoscopy (EGD) revealed a malignant appearing duodenal lesion and biopsy showed that it was compatible with germ cell tumor. Metastatic embryonal carcinoma to duodenum was diagnosed and confirmed by immunohistochemical stains. Then, the patient's situation was discussed and decided to be on a plan of four cycles of chemotherapy regimens. Testicular malignancy metastasis to GIT is uncommon, but it's important to know that there is a contact between GIT and testicular lymphatic drainage through para-aortic lymph nodes. So, even if it's rare to occur, it's still possible, and we should always be concerned about it. Mostly, diagnosis of testicular tumors begins with evaluating tumor markers such as alpha-fetoprotein (AFP), beta-subunit of human chorionic gonadotropin (B-hCG), and lactate dehydrogenase (LDH). But in contrast, all of these markers were within the normal range of their values in our case. Suspicion for metastasis and GIT involvement must be raised when dealing with a young male who had a history of testicular tumor such as embryonal carcinoma which was reported here in our case. That is very essential for avoiding potential complications and saving time in order to start management.

The Status of Spermatogenesis in Germ Cell Tumor Bearing Testis and Its Association with Metastatic Disease.

INTRODUCTION: We aimed to evaluate the status of spermatogenesis detected by histological examination of non-tumoral testicular tissues in tumor bearing testis and its association with advanced stage disease. PATIENTS AND METHODS: We retrospectively reviewed patients with testicular germ cell tumors (TGCTs) that undergone radical orchiectomy. All non-tumoral areas of the orchiectomy specimens were examined for the status of spermatogenesis. Patients were divided into two groups as localized (stage I) and metastatic (stage II-III) disease and analyzed separately for seminomatous (SGCT) and nonseminomatous germ cell tumors (NSGCT). RESULTS: Four hundred fifty-four patients were included in our final analysis. Of those, 195 patients had SGCT, and 259 patients had NSGCT. Three hundred and six patients had localized disease at the time of diagnosis. Median (Q1-Q3) age was 31 (26 - 38) years and 102 (22.5%) patients had normal spermatogenesis, 177 (39.0%) patients had hypospermatogenesis and 175 (38.5%) patients had no mature spermatozoa. On multivariate logistic regression analysis, embryonal carcinoma >50% (1.944, 95 %CI 1.054-3.585, P = .033) and spermatogenesis status (2.796 95% CI 1.251-6.250, P = .012 for hypospermatogenesis, and 3.907, 95% CI 1.692-9.021, P = .001 for absence of mature spermatozoa) were independently associated with metastatic NSGCT. However, there was not any variables significantly associated with metastatic SGCT on multivariate logistic regression analysis. CONCLUSION: Our study demonstrated that only 22.5% of patients with TGCTs had normal spermatogenesis in tumor bearing testis. Impaired spermatogenesis (hypospermatogenesis or no mature spermatozoa) and predominant embryonal carcinoma are associated with advanced stage NSGCT.

Embryonal rhabdomyosarcoma of the testis in a 17-year-old male.

Primary rhabdomyosarcoma of the testis is an exceptionally rare and highly malignant sarcoma. To date, there are only 23 reported cases in the literature. We report a 17-year-old male patient presented with massive scrotal swelling that had been progressively enlarging over seven-months. Scrotal ultrasound and contrast-enhanced CT revealed a 10 × 10cm left testicular heterogeneously enhancing mass that extends into the spermatic cord. A left inguinal orchiectomy was performed, and histopathological examinations showed findings consistent with Rhabdomyosarcoma, Embryonic-type. Primary embryonal testicular rhabdomyosarcoma has poor prognosis, particularly for adolescents, and tumour size greater than 10cm. Early diagnosis and radical orchiectomy improve the prognosis.

Epidermoid cyst of the testis: A report of three cases.

Testicular epidermoid cysts have characteristic findings. Testicular tumor markers are negative in patients with epidermoid cysts. Clear margins and sole and small testicular tumors (20 mm or less) suggest the possibility of epidermoid cyst. Testicular-sparing surgery with intraoperative frozen section examination should be performed when suspecting epidermoid cysts. Testicular epidermoid cysts are rare tumors that account for 1% of all testicular tumors and are often clinically misdiagnosed as malignant lesions. We report three cases of epidermoid cysts. The chief manifestations were scrotal induration in two patients and pruritus scrotum in one. The median age of the patients was 23 years (18-30). All tumors were determined to be sole lesions (<20 mm in diameter). Testing for tumor markers in all patients revealed negative results. We could not rule out malignancy; hence, we performed high inguinal orchiectomy in all cases. Histologically, the inner walls of the cysts were lined with stratified squamous epithelium; their contents were keratinized. All patients were diagnosed with epidermoid cysts.

Hand, foot, and mouth disease presenting with a testicular mass in an adult.

The majority of solid testicular tumors are treated with orchiectomy given the high risk of malignancy. We present a case of a testicular mass in an adult patient in the setting of recent hand, foot, and mouth disease that was managed conservatively with serial ultrasounds. Even though cases of viral-associated testicular masses are rare, this differential diagnosis should be considered in patients with a new testicular mass in the setting of recent viral infection and negative tumor markers. For these patients, observation may be an option instead of immediate orchiectomy.

A unique case of large cell calcifying type sertoli tumor.

Sertoli cells tumors are a rare testicular malignancy, with prevalence estimated to be less than 1% of testicular cancers. Furthermore, testicular cancer only accounts for approximately 0.5% of all diagnosed cancers. This is a unique case of a 19-year-old male where physical exam and ultrasonography findings revealed an intratesticular mass that, after pathologic analysis, demonstrated T1 large cell calcifying type Sertoli cell tumor which is infrequently documented in the literature.

Paratesticular cellular angiofibroma: a case report.

INTRODUCTION: Paratesticular cellular angiofibroma is a rare benign mesenchymal tumor. The optimal management is surgical resection due to the difficulty of preoperative accurate diagnosis. CASE PRESENTATION: A 51-year-old Japanese male visited our hospital complaining of asymptomatic left scrotal swelling. Physical examination revealed a nontender elastic paratesticular mass (5.5 cm in diameter). Although testicular germ cell tumor was ruled out clinically, the possibility of malignant potential remained for the tumor. Since the patient consented to complete resection, a transinguinal radical orchiectomy was performed. The pathological diagnosis revealed cellular angiofibroma. The patient recovered without perioperative complications, and no apparent recurrence was observed at 5 years after surgery. CONCLUSION: The pathological findings were compatible for cellular angiofibroma. The tumor was successfully resected, and no apparent recurrence was observed at 5 years after surgery.

Self-perceptions of masculinities and testicular cancer: Qualitative explorations.

OBJECTIVE: Masculinities have been explored in men with testicular cancer (TC), though limited contemporary research is available on traditional masculine norms important to masculine self-perception. The purpose of this research was to explore the discourse of TC experience in relation to masculine self-perception. METHODS: A qualitative descriptive study was conducted consisting of semi-structured interviews with 21 men. Men were aged between 31 and 47 (Mage = 35.7). Most men were diagnosed with Stage 1 cancer (66.6%), all men had finished active treatment and time since diagnosis ranged from 17.3 to 71.8 months (M = 47.2). Independent coding was conducted by two researchers and was refined in coding meetings with authors. Themes were developed in a predominantly deductive manner, and analysis of themes was undertaken using a reflexive analysis approach. RESULTS: Traditional masculine norms showed differing relationships to masculine self-perception. Two main themes were identified [1] Maintained or enhanced masculine self-perception and [2] threats to masculine self-perception. Subthemes demonstrated that maintaining emotional control, strength and 'winning' was important to men, and reduced physical competencies (i.e., strength, sexual dysfunction, virility) challenged self-perception. Strict adherence to traditional norms in response to threatened self-perception related to psychological distress. CONCLUSION: Leveraging traditionally masculine norms such as physical strength and control and developing flexible adaptations of masculinities should be encouraged with men with TC to retain self-perception and potentially enable better coping. Masculine self-perception of gay/bisexual men may centre around sexual functioning, though further research is required.

A nomogram for predicting risk factors of testicular salvage after testicular torsion in children.

OBJECTIVES: This study aimed to establish a nomogram for predicting the probability of testicular salvage after testicular torsion in children. METHODS: We retrospectively collected data of children with testicular torsion who were treated at Shenzhen Children's Hospital between September 2005 and August 2022. Of the training cohort, 113 patients who underwent orchiectomy and five with testicular atrophy after orchiopexy were included in the failed testicular salvage group. Additionally, 37 patients who underwent orchiopexy without postoperative testicular atrophy were included in the successful testicular salvage group. The predictive factors affecting testicular salvage were determined using univariate and multivariate logistic regression analyses; a nomogram was constructed. The nomogram was verified using data from the validation group. RESULTS: Using multivariate logistic regression analysis, the independent risk factors of testicular salvage after testicular torsion were symptom duration (p = 0.034), intratesticular blood flow (p = 0.003), spermatic cord torsion degree (p = 0.037), and monocyte count (odds ratio: 0.012, p = 0.036). A nomogram was established based on these four risk factors. In the training cohort, the area under the receiver operating characteristic curve was 0.969. The area under the receiver operating characteristic curve of the verification cohort was 0.965, indicating good discrimination ability of the nomogram. Increased symptom duration without intratesticular blood flow increased the monocyte count and spermatic cord torsion degree and decreased the success rate of testicular salvage. CONCLUSION: This prediction model could obtain the corresponding probability of testicular salvage according to the clinical characteristics of different patients with testicular torsion, providing reference for clinicians and parents.
