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.

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.

INTRODUCTION: Extramammary Paget's disease of the scrotum and penis is a relatively rare cutaneous malignant tumor. At present, its pathogenesis, and clinical and pathological characteristics are not very clear. This is controversial regarding surgical margin width to decrease the high recurrence rate. This paper aimed to report the case and review the literature of extramammary Paget's disease of scrotum and penis. CASE PRESENTATION: We presented the case of a 74-year-old male patient with the patchy erythema and pruritus in the perineum who was admitted to our department. Biopsy of the large plaque revealed Paget disease. Under the condition of ensuring negative surgical margins by rapid frozen pathology, a wide local excision of the lesion, bilateral orchiectomy, and adnexectomy were performed on the patient. Pathology revealed that many scattered vacuolated Paget cells were observed in the epidermal layer, and the diagnosis was Paget's disease of the scrotum and penis. The 2 cm outside the skin lesion was used as the initial surgical margin, and free skin flap transplantation was used to repair the surgical wound. The patient recovered well and was discharged 1 week after surgery. CONCLUSION: Currently, histopathologic biopsy is the most important diagnostic method for EMPD. Once confirmed, for patients eligible for surgical intervention, wide local excision of the lesion and rapid intraoperative frozen pathological examination should be performed as soon as possible. The skin flap transplantation is the first choice for the repair of large-scale wound after surgery.

INTRODUCTION: Schwannomas originate from the peripheral nerve sheaths and are mainly detected in the head, neck, or extremities. They are rarely encountered in the penoscrotal region. CASE PRESENTATION: Herein, we present a case of a penoscrotal schwannoma diagnosed and successfully treated in our center. A 40-year-old patient with a history of resection of a dorsal penile schwannoma presented with multiple nodular lesions at the scrotum, penile shaft, and radix, which were first noticed 5 years before his current presentation. He complained about penile pain and dyspareunia. Magnetic resonance imaging was performed for preoperative diagnosis. All nodular lesions were resected while preserving the neurovascular structures. The histopathological examination revealed benign lesions. The patient's complaints were resolved, and there was no recurrence during the 1-year follow-up. CONCLUSION: The primary treatment is surgical excision. The patients need close follow-up regarding the risks of recurrence and malignant transformation.

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 P16ï¼which 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.

Neurofibroma of the scrotum is a very uncommon benign neoplasm, specifically when it affects teenagers and is not associated with neurofibromatosis type I. To the best of our knowledge, only a couple of cases of neurofibroma in children have been documented. Here, we report a case study of a 17-year-old boy who had a giant scrotal lump for ten years masquerading clinically as filariasis. A provisional diagnosis of benign nerve sheath neoplasm was made based on cytology findings. The lump was surgically removed from the patient, and a histopathological and immunohistochemistry examination established the diagnosis of neurofibroma. The combined clinical, preoperative cytological, histological, and immunohistochemistry findings were not presented in the literature in any of the formerly documented cases of scrotal neurofibroma. The current case expands the spectrum of differential diagnoses for scrotal tumours that clinicians have previously observed.

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 (â¦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.

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.

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.

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.

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.

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.

ABSTRACT: Electron beams represent an important treatment modality for providing an accurate dose of therapy to superficial cancers. This case reports important findings of dermal invasion in patients with extramammary Paget's disease (EMPD) using microscopic measurements and electron beam coverage. EMPD is a rare cutaneous adenocarcinoma generally arising in the anogenital region. Surgery is still a curable treatment option for patients with EMPD, whereas radiation therapy (RT) is an alternative for inoperable cases and is necessary in cases where surgery is not performed. This case report describes our experience and reviews the relevant literature on the feasibility of electron RT according to the dermal invasion length. An 80-year-old patient was diagnosed with EMPD and presented for definite radiation treatment. We observed no grade 3 toxicities during electron RT, and at the last follow-up visit, no signs of relapse were observed. There are no reports of electron irradiation as a feasible treatment option for EMPD considering the epidermal invasion length.

Testicular and scrotal abnormalities can occur in children, adolescents, and adults. The lesions, often accompanied by pain and swelling/enlargement of the scrotum, can cause anxiety in patients and their parents. Regardless of age, proper diagnosis is based on adequate anamnesis and physical examination. Color Doppler ultrasound is the first-line test in the differential process of testicular and scrotal diseases. Testicular and scrotal lesions require differentiation for benign and malignant processes as well as therapeutic management, including urgent surgical intervention. The aim of this paper is to present the most common causes of testicular and scrotal abnormalities in pediatric and adult patients and to outline the symptoms and diagnostic and therapeutic management.

La calcinosis escrotal es una enfermedad benigna e infrecuente que se presenta en adultos de mediana edad, con múltiples nódulos asintomáticos a nivel de la piel del escroto. Algunos autores vinculan la aparición de estas lesiones a la calcificación secundaria de quistes epidérmicos o ecrinos. Cuando no se encuentra relacionada con dichas entidades ni con alteraciones del metabolismo fosfocálcico, el cuadro se considera idiopático. El tratamiento de elección es quirúrgico, en caso de impacto en la calidad de vida o relevancia estética para el paciente. (AU)
Scrotal calcinosis is a rare, benign disease that presents in middle-aged adults with multiple asymptomatic nodules on the skin of the scrotum. Some authors link the appearance of these lesions to the secondary calcification of epidermal or eccrine cysts. When it is not related to these entities or to alterations in phosphocalcic metabolism, the condition is considered idiopathic. The treatment of choice is surgical, in case of impact on the quality of life or aesthetic relevance for the patient. (AU)
