RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Background: Extramammary Paget's disease (EMPD) is a rare epithelial malignancy, and approximately 30%-40% of EMPD patients overexpress human epidermal growth factor receptor 2 (Her-2). Currently, there are no established standard treatments for advanced EMPD while anti-Her-2 therapy is recommended for Her-2-positive cases. Case presentation: Here, we report a 51-year-old male diagnosed with advanced Her-2-positive EMPD, presenting with numerous lymph node metastases. This patient received disitamab vedotin (an antibody-drug conjugate, targeting Her-2) combined with serplulimab as first-line treatment. After seven cycles of combination therapy, the patient tolerated the treatment well and the lymph node lesions continued to shrink. However, the patient developed immunotherapy-related pneumonia following the eighth treatment. Hormone therapy was administered while all the anti-tumor therapies were halted. After the pneumonia improved, the patient underwent positron emission tomography-computed tomography, revealing a complete response to his tumor. To consolidate the effect, he received another five cycles of disitamab vedotin monotherapy as maintenance therapy, without experiencing any adverse events. To date, the patient has remained in good health without any recurrence 10 months after drug discontinuance. Conclusion: Disitamab vedotin combined with immunotherapy demonstrated a long-term clinical benefit in advanced Her-2-positive EMPD. For rare solid tumors with Her-2 overexpression, disitamab vedotin combined with immunotherapy might offer a viable therapeutic choice.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Since the scrotum is rarely exposed to sunlight, basal cell carcinoma (BCC) development in this area is an uncommon occurrence. As result, there is a scarcity of research covering this particular presentation, which poses a diagnostic and therapeutic challenge for clinicians. The objective of this systematic review is to provide a thorough overview of scrotal BCC, including a summary of its clinical characteristics, and microscopic subtypes. It also seeks to discuss the many techniques used in the management of this uncommon clinical presentation. Utilizing data from 1957 to October 2023, a systematic review of PubMed and Wiley Online Library was conducted to identify all cases of scrotal BCC with various presentations and managements. A total of 73 patients were included. The median patient age was 65.9 years (range 42 to 87). All studies were either case reports or case series. Our review shows that treatment with Mohs micrographic surgery (MMS), leads to a superior patient outcome based on anecdotal evidence in select cases. To deepen our understanding of Mohs surgery's efficacy in treating scrotal BCC, it is imperative to conduct more robust research in the form of randomized clinical trials.

RESUMEN

BACKGROUND: Palmar-plantar erythrodysesthesia (PPE) is a slowly developing cutaneous reaction commonly experienced by patients treated with fluoropyrimidines. While erythrodysesthesia normally presents in a palmar-plantar distribution, it can also present with genital involvement, but this presentation is likely underreported and incorrectly attributed to an acute reaction from radiation therapy. This article aims to define erythrodysesthesia of the penis and scrotum as a rare but significant side effect of capecitabine. CASE PRESENTATION: We identified five cases of moderate to severe penis and scrotal erythrodysesthesia over a 2-year period at a large tertiary cancer center, representing an estimated incidence of 3.6% among male patients with rectal cancer who were treated with fluoropyrimidine-based chemoradiation within our institution. CONCLUSIONS: Improved understanding of erythrodysesthesia involving the penis and scrotum can facilitate early identification and treatment of symptoms, and possibly prevent the discontinuation or delay of cancer treatment in patients treated with capecitabine and similar drugs. These clinical advances would improve and prolong patient quality of life during cancer treatment and prevent complications that result in hospitalization.

RESUMEN

OBJECTIVE: To contribute to the literature by sharing the clinical presentation, surgical approach, postoperative complications management, and follow-up protocols of the patients we operated on due to intrascrotal extratesticular mass. METHODS: Thirty-two patients admitted due to intrascrotal extratesticular mass were included in the study. Demographic and clinical characteristics of the patients such as age, initial clinical presentation, physical examination, radiological imaging findings, such as scrotal Doppler ultrasonography and magnetic resonance imaging, mass size, and characteristics, surgical treatment procedures, operation notes, and patient follow-up visits were retrospectively examined and evaluated from the patient files. RESULTS: The median age of the 32 individuals included in the study was 52 (interquartile range: [45.0-60.5]) years. The primary reason for initial presentation was a palpable mass in 25 (78.1%) patients, pain in 13 (40.6%) patients, and scrotal swelling in 8 (25%) patients. The median mass diameter was 4.4 (interquartile range: [3.1-5.7]) cm. Surgical treatment involved inguinal excision in 29 cases (90.6%) and inguinoscrotal excision in 3 cases (9.4%). All patients were treated with testicle-sparing surgery. The most common tumor location, observed in 27 cases (84.3%), was the epididymis. The most frequent histopathological diagnosis was epididymal cyst, identified in 13 patients (40.6%). Pathology results showed that the mass was removed with negative margins in all patients. CONCLUSION: Testicular-sparing surgery through the inguinal approach is one of the surgical methods that can be preferred for intrascrotal extratesticular masses. This approach can both preserve the testicle and achieve successful surgical results. Studies with larger samples are needed on this subject. TRIAL REGISTRATION: This study was approved by the Erzurum Medicine Faculty University Local Ethics Committee (approval number: BAEK 2023/08-105).

RESUMEN

Acute genital diseases can occur at any age and are characterized by complaints of various kinds of the external genitalia. Pain, swelling, and redness of the scrotum, adjacent groin region, and immediate surroundings are the leading symptoms, the severity of which may vary. In addition, peritonitic symptoms such as nausea, vomiting, and circulatory sensations may be present and are comparable to symptoms of an acute abdomen. The term "acute scrotum" encompasses various clinical entities, where scrotal symptoms are predominant and represent a urological emergency situation. Immediate and comprehensive diagnostics are necessary to ensure timely management in case of necessary surgical intervention.

RESUMEN

We report the case of a young man who has never had any sexual contact presenting with a large scrotal lump with secondary bacterial infection. He reported no prior warts - genital or cutaneous. On examination, he had a large pink cauliform mass on the scrotum with four smaller but similar satellite lesions. Appearances were thought to be consistent with giant condyloma of Buschke and Lowenstein. Once superinfection was treated with oral antibiotics, he had a trial of imiquimod without success and was then referred to urology. After surgical excision, pathology concluded it was an inflamed fibroepithelial polyp with no malignant changes. To our knowledge, this is the first case report of a giant scrotal fibroepithelial polyp with characteristic gross warty features in an adult.
