Scrotoliths in the testicular tunica vaginalis in an elderly male cadaver: clinical implications.

Scrotoliths, or "scrotal pearls," are calcified fibrous loose bodies found within the tunica vaginalis, often seen during radiological evaluation or autopsies. Chronic inflammation due to trauma, parasitic infestations, and torsion and subsequent detachment of the appendices of the testis or epididymis are postulated mechanisms suggested for their formation. They are benign but can mimic a tumor. Scrotoliths can be diagnosed with high-resolution ultrasonography. Here, we report a case in which, during routine dissection, two scrotoliths were found within the tunica vaginalis of the left testis in an elderly male cadaver. Histologically, the central portion of the scrotoliths exhibited concentric collagen lamellae that enclosed calcified remains of tissue debris. There were no arterioles, venules, or microfilarial larvae seen within them. Awareness about the histological findings can help understand the mechanism that led to their formation.

[Acute scrotum in children]. / ABC om Akut skrotum hos barn.

Acute scrotum in a child is common, and the main underlying conditions are torsion of intrascrotal appendages, epididymitis, testicular torsion and idiopathic scrotal edema. The main diagnostic aim is to confirm or rule out testicular torsion, since this may lead to irreversible ischemia within hours. The diagnostics can be difficult, especially in prepubertal boys, but consist of a thorough history and clinical examination, the use of a clinical prediction score, and sometimes ultrasound with doppler. However, none of these tools can with completely accuracy rule out a testicular torsion, and uncertainty should prompt an acute scrotal exploration. The treatment of a testicular torsion is detorsion and bilateral orchidopexy, or unilateral orchidectomy in case of a completely necrotic testicle. Treatment of the other underlying conditions is often only symptomatic, and follow-up is often not required.

Scrotal Trauma Treatment and Outcomes.

INTRODUCTION: Genitourinary tract injuries have been reported to account for 3% to 10% of trauma patients, and scrotal injuries have been reported to comprise 71% of male genital trauma. Scrotal trauma is particularly prevalent in males 10 to 30 years of age, thus posing a potential threat to fertility. Scrotal trauma can be blunt or penetrating in nature, and the mechanism of trauma can have an impact on the management and outcomes of this type of injury. METHODS: A retrospective chart review of adult patients who presented with scrotal trauma to a single large level I trauma center from January 1, 2000, to June 1, 2022, was conducted to assess the relative occurrence and type of trauma (blunt vs penetrating), as well as differences in the management, duration of hospital stay, and need for orchiectomy between these 2 types of injury. RESULTS: There were 102 patients included in this study, with an average age of 39.5 years (18.7-77.2 years). Fifty-six patients had blunt scrotal trauma, and 46 had penetrating scrotal injury. There was not a statistically significant difference in the percentages of blunt versus penetrating trauma (P < = 0.3729). Patients with penetrating trauma were more likely to be inpatient than those with blunt trauma (69.6% vs 42.9%; P < = 0.013; 95% CI, 0.062-0.473). A total of 61 patients were treated conservatively (44 and 17 patients in the blunt and penetrating trauma groups, respectively). Overall, 41 patients required surgical intervention: 12 who had blunt trauma and 29 who suffered penetrating injury. Surgical treatment was more common for penetrating trauma than for blunt trauma (63.0% vs 21.4%; P <0.0001; 95% CI, 0.220-0.612). Eleven patients underwent orchiectomy - 4 from the blunt trauma group and 7 from the penetrating trauma group; the rate of orchiectomy was not significantly different between the 2 groups. CONCLUSIONS: In this study, blunt scrotal trauma was slightly more common than penetrating injury, but the difference did not reach statistical significance. Blunt scrotal trauma was associated with a higher rate of conservative treatment. Further study is needed to better understand the impact of scrotal trauma on future fertility.

Transcutaneous Neuromuscular Electrical Stimulation for Treating Varicocele-Induced Scrotal Pain.

Varicocele is a prevalent vascular disorder affecting the male reproductive system, leading to scrotal pain and testicular dysfunction. Epidemiological studies have shown that varicocele occurs in approximately 10% to 15% of adult males, while scrotal pain affects 2% to 10% of the population. Currently, clinical treatment options for varicocele-induced scrotal pain include general therapy, medication, and surgery. Among these, surgical intervention is considered the most effective method, boasting a success rate of 80%. However, it carries risks such as postoperative bleeding, infection, and recurrence, making it less desirable for some patients. In recent years, transcutaneous neuromuscular electrical stimulation has gained wide acceptance for treating various andrological conditions, including erectile dysfunction and premature ejaculation, yielding positive outcomes. This non-invasive technique offers a promising alternative for managing varicocele-induced scrotal pain, potentially reducing the need for surgical intervention and its associated risks. Its growing popularity underscores the need for further research and clinical trials to validate its efficacy and safety in treating this condition.

[Well-differentiated papillary mesothelial tumour of the tunica vaginalis: A case report].

The mesothelium, which consists of a monolayer of mesothelial cells, extends over the surface of the serosal cavities (pleura, pericardium, peritoneum and tunica vaginalis). Mesothelial tumours of the tunica vaginalis is rare compared with those arise from pleura or peritoneum. According to World Health Organization 2022 Classification of Urinary and Male Genital Tumours (5th edition), mesothelial tumours of the tunica vaginalis were categorized into adenomatoid tumour, well-differentiated papillary mesothelial tumour (WDPMT) and mesothelioma. Since WDPMT of tunica vaginalis was rare, there was no consensus concerning the treatment of it. In this case report, a 29-year-old man who had endured intermittent right scrotal pain for 8 months, aggravating scrotal pain for 2 weeks was admitted. No symptoms, such as frequent, urgent, or painful urination were shown. Physical examination revealed the enlargement and tenderness of right scrotum, with no signs of lifting pain. The most recent scrotal ultrasonography before surgery revealed right hydrocele with maximum depth of 4 centimeters and poor blood flow of right testis. Under the circumstance of patient' s chronic history of testicular hydrocele, he underwent an emergency operation of right scrotal exploration and hydrocelectomy under epidural anesthesia. After opening the vagina tunic cavity, spot-like bleeding was observed on the right testicle, epididymis and vaginalis surface. The vaginalis was obviously thickened and the inner and outer walls were smooth. The post-operative histopathology revealed a grayish-brown tissue with a thickness of 0.3-0.5 cm, smooth inner and outer walls, and a suspected WDPMT with a diameter of 1. 5 cm. Immunohistochemical staining showed positive for Calretinin, BAP1, WT-1, CK5/6, D2-40 and P16，which confirmed the diagnosis of WDPMT. To sum up, the purpose of this case report was to raise awareness of a rare disease WDPMT, which was usually asymptomatic and could be diagnosed by pathology and immunohistochemistry. The disease should be differentiated from testicular torsion, epididymitis, orchitis and oblique inguinal hernia in symptoms, and from malignant mesothelioma and adenomatoid tumour in pathology. Because of the rarity of the cases, there was no unified standard for the treatment of WDPMT at present. The common treatment methods reported in literature included orchidectomy and vaginectomy. Due to the lack of understanding of this disease, postoperative follow-up was still recommended for at least 5 years.

Poor sleep quality is predictive for higher pain levels in patients with chronic scrotal pain, regardless of body perception, biological rhythm, anxiety, and depression.

OBJECTIVES: To investigate the association between pain and sleep quality, anxiety, depression, body perception, and biological rhythm in chronic scrotal pain (CSP). MATERIAL AND METHODS: This cross-sectional study of 140 CSP patients was conducted between January and October 2023. The patients were separated into groups according to the Visual Analogue Scale (VAS) score as group 1 (score<3, n=27), group 2 (score: 3-6, n=84), and group 3 (score>6, n=29). In addition to demographic data, the points were recorded from the Body Image Scale (BIS), Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN), Hospital Anxiety and Depression Scale (HADS), and the Pittsburgh Sleep Quality Index (PSQI). RESULTS: The median (IQR) age of patients was 33 (20) years and the median (IQR) duration of pain was 5 (9) months. Group 3 patients had more anxiety (24.1% vs. group 1: 22.2%; group 2: 8.3%; P=0.03) and depression (55.2% vs. group 1: 40.7%; group 2: 29.8%; P=0.04) symptoms. No statistical differences were determined between the groups according to the BIS (P=0.54). The median (IQR) total BRIAN score was higher in group 3 than group 1 [37 (11) vs. 33 (13), P=0.03]. Higher rates of poor sleep quality were determined in group 3 patients according to the PSQI (75.9% vs. group 1: 48.1%; group 2: 51.2%; P=0.04). The VAS score was found to be positively associated with pain duration, total BRIAN score and PSQI score (r=0.31, P<0.001; r=0.17, P=0.04; r=0.23, P=0.006, respectively). The PSQI score was found to be an independent predictor for a higher VAS score (HR: 1.14, P=0.01). CONCLUSION: The results of this study suggest that poor sleep quality may influence the perceived intensity of pain. LEVEL OF EVIDENCE: II.

Solitary Acute Necrotic Scrotal Ulcer in a Young Patient.

A healthy young male patient was referred to the department of dermatology for evaluation of a solitary painful scrotal ulceration that developed rapidly 48 hours before consultation. What is your diagnosis?

The downregulation of genes encoding muscle proteins have a potential role in the development of scrotal hernia in pigs.

BACKGROUND: Testicular descent is a physiological process regulated by many factors. Eventually, disturbances in the embryological/fetal development path facilitate the occurrence of scrotal hernia, a congenital malformation characterized by the presence of intestinal portions within the scrotal sac due to the abnormal expansion of the inguinal ring. In pigs, some genes have been related to this anomaly, but the genetic mechanisms involved remain unclear. This study aimed to investigate the expression profile of a set of genes potentially involved with the manifestation of scrotal hernia in the inguinal ring tissue. METHODS AND RESULTS: Tissue samples from the inguinal ring/canal of normal and scrotal hernia-affected male pigs with approximately 30 days of age were used. Relative expression analysis was performed using qPCR to confirm the expression profile of 17 candidate genes previously identified in an RNA-Seq study. Among them, the Myosin heavy chain 1 (MYH1), Desmin (DES), and Troponin 1 (TNNI1) genes were differentially expressed between groups and had reduced levels of expression in the affected animals. These genes encode proteins involved in the formation of muscle tissue, which seems to be important for increasing the resistance of the inguinal ring to the abdominal pressure, which is essential to avoid the occurrence of scrotal hernia. CONCLUSIONS: The downregulation of muscular candidate genes in the inguinal tissue clarifies the genetic mechanisms involved with this anomaly in its primary site, providing useful information for developing strategies to control this malformation in pigs and other mammals.

Local Cutaneous Scrotal Involvement of Paratesticular Mesothelioma.

ABSTRACT: Paratesticular mesothelioma (malignant mesothelioma arising from the tunica vaginalis of the testis) represents a small proportion of mesothelial neoplasms, and cutaneous involvement by paratesticular mesothelioma is very rare. Cutaneous involvement can manifest as scrotal subcutaneous nodules from regional spread, distant metastasis, or direct extension through surgical scars. Mesothelioma has 3 histopathologic classifications that include epithelioid, biphasic, and sarcomatoid, which is rarely seen in paratesticular mesothelioma. Given the rarity of this condition, cutaneous mesothelioma may be misdiagnosed as histologic mimics, such as metastatic adenocarcinoma or adnexal neoplasms; thus, appropriate immunohistochemical workup and clinical correlation are required to make an accurate diagnosis. In this case, a 75-year-old man with a history of paratesticular mesothelioma, status postorchiectomy, presented with right-sided scrotal swelling, erythema, and subcutaneous nodules. These nodules were identified as local recurrence with cutaneous involvement by paratesticular mesothelioma on histopathologic examination. This case highlights the clinical and histopathologic features of this diagnosis and underscores the importance of dermatopathologists being aware of this condition to ensure accurate diagnosis.

New classification of the penoscrotal positional anomalies.

BACKGROUND: The aspect of sexual differentiation and the mechanism controlling the position of genitalia, which represents one of the most substantial differences between the sexes, is still poorly understood. Minor cases and some variants of penoscrotal transposition (PST) are unreported, and obvious cases were classified broadly and confused with other unrelated anomalies. METHODOLOGY: Relevant literature published till 2022 were reviewed then organized, recapitulated, and presented in comparison with the findings and data of 65 child diagnosed with PST. So, an integrated comprehensive approach to this uncommon condition enabled a new classification including few unreported variant cases, which were complemented. RESULTS: PST is classified herein into a cephalic or caudal scrotal migration, the cephalic type subdivided into major and minor subtypes the latter type subdivided into bilateral, unilateral or central subtypes. Cases of caudal scrotal regression is an unreported anomaly in which the scrotum located caudally, as constant association with epispadias/exstrophy anomalies leaving a wide distance between the fixed penis and the scrotal sacs. CONCLUSION: PST is not rare as it was believed, it occurs in two directions; cephalic and caudal directions. Scrotal caudal regression anomaly was not described before, as well the PST presented as an inguinal hernia.

[Pedunculated Giant Condyloma Acuminatum of the Scrotum].

The patient was a 71-year-old male whose chief complaint was a scrotum mass. The mass had gradually increased in size without any associated symptoms. The physical examination revealed a pedunculated, radish brown, and elastic soft tumor (4. 5×3. 5×3. 0 cm) in the right scrotum. Blood chemical analysis of HbA1c and squamous carcinoma antigen were 8. 3% and 38. 4 ng/ml (≦1. 5), respectively. This tumor was successfully treated with surgical resection. Histopathological examination showed condyloma acuminatum without malignant findings. Giant condyloma acuminatum commonly affects the genital and perianal areas. An immunocompromised state generally exists in the background of the patients.

[A Case of Urethral Foreign Body from 40 Years Ago with Scrotum Abscess and Urethroscrotal Fistula].

A 70-year-old male came to our clinic with a high fever and left scrotal swelling. Following a diagnosis of left-side epididymitis, antibiotic treatment was started, though the swelling did not improve. Since an additional examination revealed an abscess in the left scrotum, scrotal incision and drainage were performed. Although the symptoms subsided, urine outflow from the incision was observed. The patient then noted that he had inserted a glass ball into the urethral meatus when he was about 30 years old. It was considered that an abscess and fistula had formed due to inflammation caused by the foreign body. Thus a transurethral surgical procedure was used for crushing and removal. The fistula disappeared within three months after the operation and the patient has not been affected by dysuria since that time. Symptoms may appear several years following insertion of a foreign body into the urethra. To the best of our knowledge, the present case is the longest term of indwelling, approximately 40 years, following insertion of a foreign body reported in Japan.

Scrotal migration of a ventriculoperitoneal shunt.

Ventriculoperitoneal shunt (VPS) is the most common procedure done for hydrocephalus in the paediatric population. While shunt infection and shunt malfunction remain the most common complications, shunt migration is not frequently observed. Being present in a large peritoneal cavity, theoretically, a shunt can travel to a variety of locations. Even among these, scrotal migration is quite uncommon. This case highlights the significance of keeping this possibility in mind while evaluating a case of shunt malfunction. It also discusses various nuances of surgically managing scrotal migration.

Paratesticular fibrous pseudotumour: a rare cause of an intrascrotal mass.

This report describes a boy in his early adolescence who was referred to a urologist with a large, painless right scrotal mass. Following a thorough workup, the patient underwent surgical removal of the mass, which was revealed to be a paratesticular fibrous pseudotumour (PFP) on histopathological analysis. This diagnosis is rare and can often prove difficult to distinguish from a malignant lesion within the scrotum. We have conducted a review of the current literature surrounding PFP to compliment the case discussion.
