RESUMEN
BACKGROUND: Leiomyosarcoma is a tumor that can develop in any organ that contains smooth muscles. Although leiomyosarcoma is common, its epididymal localization is quite rare. CASE PRESENTATION: A 79-year-old male Chinese Han patient presented with mild pain in the right groin and scrotum for 3 years concomitant with right scrotal swelling. Ultrasonography and magnetic resonance imaging of the scrotum showed a irregular and heterogeneous mass that was extratesticular. Right high orchiectomy was performed, and pathological examination of the resected specimen confirmed the diagnosis of leiomyosarcoma of the epididymis with surgical margins clear of tumor. CONCLUSION: Epididymal leiomyosarcoma is rare and difficult to diagnose preoperatively. The final diagnosis of epididymal leiomyosarcoma requires histologic examination. Resection must be extensive and complete. The effect of chemotherapy and radiation on the epididymal leiomyosarcoma remains unclear. Recurrence is common, so follow-up is necessary.

Fifteen male dogs with squamous cell carcinoma of the external genitalia were admitted for further investigation and surgical management between 1994 and 2020. The dogs belonged to various breeds. Thirteen dogs were intact and two were castrated with a median age of 8 years and a median weight of 28 kg. Seven dogs were white-coated and eight nonwhite coated. Scrotal ablation and orchiectomy were performed in four dogs, partial penile amputation in two, partial penile amputation plus partial preputial ablation in one, penile amputation, and scrotal urethrostomy in seven, and local preputial excision in one dog. Postoperative complications included hemorrhage in 10 dogs, bruising at the urethrostomy site in seven, and urethrostomy dehiscence in one dog. Tumor recurrence was recorded in six dogs. Dogs with poorly differentiated tumors that had tumor recurrence had shorter survival and worse prognosis compared to those with well and moderately differentiated tumors. The mean survival time was 48.132 months. After a median follow-up of 23 months (range: 8 to 72 months), eight dogs were alive, five were euthanized and two dogs died from unrelated causes. Surgical excision seems to be a treatment option for dogs with squamous cell carcinoma of the external genitalia.

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.

BACKGROUND: Epididymal tumors, especially malignant tumors, have low incidence and are rare in our clinical work. However, they may progress quickly and have poor prognosis. For such rare clinical cases with extremely low incidence rates, and as they are prone to misdiagnosis and missed diagnosis and have a very poor prognosis, clinical workers need to pay special attention and consider the possibility of primary epididymal malignant tumors. CASE REPORT: A 63-year-old Chinese male patient from Asia was admitted due to scrotal pain. Upon examination, an abnormal lesion was found in the right epididymal region. After thorough evaluation, surgical resection was performed, and the postoperative pathological result confirmed the presence of epididymal adenocarcinoma. After further ruling out secondary lesions, primary epididymal adenocarcinoma was considered. Right retroperitoneal lymph node dissection was performed under laparoscopic for treatment, and 1/11 lymph node metastasis was detected after surgery. The patient is currently under close follow-up. CONCLUSIONS: The number of clinical cases of primary epididymal malignant tumors is very limited, there is currently no standardized diagnosis and treatment process, and there is a lack of systematic evaluation methods regarding the effectiveness of different treatment options such as chemotherapy, radiotherapy, immunotherapy, and targeted therapy. In addition, the outcome is difficult to predict. In this article, we reviewed relevant literature and systematically elaborated on the diagnosis and treatment of epididymal malignant tumors, hoping to provide useful information for relevant experts.

OBJECTIVES: Spermatic cord sarcomas are exceedingly rare, often misdiagnosed and subsequently improperly treated at local hospitals. This retrospective study looked at the oncological outcomes of spermatic cord sarcoma cases managed with curative intent resection at a tertiary referral sarcoma centre. We specifically studied how initial inadequate resections impact the oncologic outcomes compared to primary tumour resections at the reference centre. METHODS: One hundred eighteen consecutive patients affected by primary, localized spermatic cord sarcoma surgically managed at our reference centre from January 2001 through January 2021 were included. Primary endpoints were local relapse free (LRFS), distant metastasis free (DMFS) and overall survival (OS). These outcomes were evaluated with multi-nomial logistic regression and Cox proportional hazards regression models for a co-relation to known patient, tumour and treatment-related prognostic factors, including a prior inadequate resection and time from diagnosis to a complete oncologic resection as independent variables. Secondarily, we compared the above variables and treatment intervals among the subgroups of primary versus re-resection surgery. RESULTS: Over a median follow-up of 54 months (IQR 25-105), 12 patients (10.2%) developed local recurrence (LR) and 14 (11.6%) had distant metastasis (DM). 5-year local relapse (LRFS) and distant metastasis-free survival (DMFS) were 89.3% and 86.5%, respectively. Higher tumour grade and size were associated with a worse DMFS (p=<0.05). Likewise, marginal (R1) resection correlated with an inferior LRFS (p=< 0.05). Eighty-four patients (71.2%) had their initial diagnosis established on an inadequate surgical excision performed in a local hospital, followed by a re-excision at our centre (Re-resection group). During the same period, 34 (28.8%) were managed primarily with biopsy and treatment at our reference centre (Primary-resection group). The two groups had statistically significant differences in tumour size, histopathology, surgery duration, rate of postoperative complication and R0 resection (p < 0.005). Additionally, the difference in time intervals to achieve the treatment targets was statistically insignificant and did not correlate to the risk of recurrence as an independent variable. Residual disease was present in 51.2 % (n = 43) of the re-excision specimens. However, following a complete R0 resection, this did not correlate with a higher risk of recurrence (p = 0.481). CONCLUSION: Prompt referral to a tertiary centre, where multidisciplinary evaluation and sound oncologic resections are the standard of treatment, can align the OS and DFS of patients receiving incomplete surgery elsewhere to those treated primarily in referral centres. The primary determinant of prognosis remains surgical margin, tumour size and grade.

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.

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.

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.

Liposarcomas of the paratesticular tissue is a rare pathological entity. The symptoms are similar to inguinal hernias or hydroceles. We present the case of an 84-year-old man with a rare paratesticular liposarcoma that manifested as painless right hemiscrotal swelling. Testicular tumour markers were negative. Imaging revealed a heterogeneous mass with a fat component. He underwent a radical orchiectomy on the left side to remove the associated mass. This revealed dedifferentiated liposarcoma (DDLS) with rhabdomyoblastic differentiation and MDM2 amplification. The surgical margins were negative, and the patient had a metastatic workup that included magnetic resonance imaging (MRI) of the abdomen and pelvis. Because of the disease's rarity, there is no clear agreement on radiotherapy and chemotherapy roles.

AIM: Liposarcoma of the spermatic cord (LSC) is a tumour often mistaken for common inguinal swelling as hernia and the aim of this work is to present our case with a review of the Literature to define the management of this rare condition. MATERIAL OF STUDY: A systematic review has been realised, considering English language articles published on Pubmed, between 1956 and 2022, using as key words "Liposarcoma of the spermatic cord". RESULTS: 160 studies described 420 cases of LSC and in 40 cases the patient had undergone surgery with an initial diagnosis of inguinal hernia. DISCUSSION: LSC is a very rare entity of genitourinary malignancies, occurring more often in the spermatic cord and diagnosis can be difficult. Our case and Literature data confirm the role of imaging in not conventional inguinal swelling, to avoid diagnostic mistakes and to define preoperatively the correct surgical management. CONCLUSIONS: Imaging is mandatory in case of diagnostic doubt. The recommended treatment is a radical high orchiectomy with clear margins. A long follow-up period is necessary to detect a local recurrence which may occur even several years after the primary therapy. KEY WORDS: Inguinal swelling, Liposarcoma, Spermatic cord.

BACKGROUND: Squamous cell carcinoma (SCC) of the scrotum is a rare and aggressive cancer. There are no established guidelines on the management of scrotal SCC. OBJECTIVE: To analyze the clinical management and outcomes of scrotal SCC. PATIENTS AND METHODS: A retrospective analysis of patients diagnosed with primary scrotal SCC over a 10-year period was performed. The type of surgery, tumor stage and histological subtypes, recurrence rate and metastases, cancer-specific mortality (CSM), and other-cause mortality (OCM) were analyzed. RESULTS: Between 2012 and 2022, a total of 10 men were identified with primary scrotal SCC. The median (interquartile, IQR) age was 65.5 (55-77) years. Wide local excision was performed in 9 patients and 1 patient underwent a total scrotectomy. The pathological T-stage was: pT1, nâ¯=â¯3; pT2, nâ¯=â¯1; pT3, nâ¯=â¯5 (50%); pT4, nâ¯=â¯1. Four patients had pathologically positive inguinal lymph nodes and 2 had distant metastatic disease at presentation. At a median (IQR) follow-up of 10.5 (4-31) months 5 patients died, of which 3 died from scrotal SCC. CONCLUSION: Scrotal SCC is extremely rare in the UK with only 10 primary cases identified in our center over the past 10 years. Surgical resection of the tumor and appropriate inguinal node staging are required due to a high proportion of cases which metastasize to the inguinal lymph nodes. PATIENT SUMMARY: Scrotal cancer is rare. 10 cases were diagnosed over 10 years at a single center. Around half had disease spread to the groin nodes or distant organs at presentation. Surgical resection was required in all patients. At the time of analysis, half of the patients are alive. Due to the rarity and aggressiveness of the cancer, management should be carried out within a specialist center.

Hemolymphangioma is an uncommon benign tumor type that commonly occurs in the head and neck. Primary spermatic cord hemolymphangioma (SCH) with only several reported, however, is extremely rare. Clinical diagnosis can be challenging because of its rarity. Although spermatic cord hemolymphangiomas are benign tumors, there is still a high recurrence rate in postoperative. A 15-year-old boy presented to our hospital with complaints of scrotal for 15 days and did not have other associated symptoms. The male genital color Doppler ultrasound revealed that a cystic echo in the left spermatic cord region and above the testes was about 32 mm × 20 mm × 14 mm. He underwent left en bloc scrotum tumor resection under general anesthesia, and pathologic examination showed SCH. He was discharged from the hospital in the second postoperative day. After 1-month follow-up, the patient recovered well without recurrence. The patient is currently in follow-up phase. Up to date, only a few cases have been reported in the literature about SCH. So, we hope to raise the awareness of the diagnosis of SCH in clinical practice although this case.

A 13-year-old, intact male mixed-breed dog was referred to our clinic for lethargy and asthenia following an episode of gastroenteritis. As an incidental finding during abdominal ultrasound, a mass on the right spermatic cord was seen. Cytology of the mass revealed a monomorphic population of large, round cells with a lymphoid appearance. A bilateral orchiectomy was conducted, and histopathology revealed the presence of a B-cell lymphoma in the right spermatic cord. Based on clinical staging, which showed no involvement of other sites, no additional treatment was administered. Recheck evaluations were scheduled for every 3 mo thereafter. Five months after surgery, the dog developed left central vestibular syndrome with a paradoxical right-sided head tilt. An MRI of the brain showed multifocal lesions and, due to a rapidly worsening clinical condition, the dog was humanely euthanized. The histopathology of the brain lesions was consistent with B-cell lymphoma. Key clinical message: This is the first report of a primary spermatic cord lymphoma relapsing to the brain in a dog. Although rare, spermatic cord tumors should be included among the differential diagnoses for masses arising from the spermatic cord. If lymphoma is diagnosed, location to other sites, especially to the central nervous system, should be considered.
Un cas de lymphome à cellules B du cordon spermatique récidivant au cerveau chez un chien. Un chien de race mixte mâle intact de 13 ans a été référé à notre clinique pour léthargie et asthénie à la suite d'un épisode de gastro-entérite. Comme découverte fortuite lors d'une échographie abdominale, une masse sur le cordon spermatique droit a été observée. La cytologie de la masse a révélé une population monomorphe de grosses cellules rondes d'aspect lymphoïde. Une orchidectomie bilatérale a été réalisée et l'histopathologie a révélé la présence d'un lymphome à cellules B dans le cordon spermatique droit. Sur la base du stade clinique, qui n'a montré aucune implication d'autres sites, aucun traitement supplémentaire n'a été administré. Des évaluations de contrôle étaient programmées tous les 3 mois par la suite. Cinq mois après la chirurgie, le chien a développé un syndrome vestibulaire central gauche avec une inclinaison paradoxale de la tête du côté droit. Une IRM du cerveau a montré des lésions multifocales et, en raison d'une détérioration rapide de l'état clinique, le chien a été euthanasié sans cruauté. L'histopathologie des lésions cérébrales correspondait à un lymphome à cellules B.Message clinique clé :Il s'agit du premier rapport d'un lymphome primaire du cordon spermatique récidivant au cerveau chez un chien. Bien que rares, les tumeurs du cordon spermatique doivent être incluses dans les diagnostics différentiels des masses provenant du cordon spermatique. Si un lymphome est diagnostiqué, la localisation vers d'autres sites, en particulier vers le système nerveux central, doit être envisagée.(Traduit par Dr Serge Messier).

A 63-year-old man presented with right scrotal swelling. A physical examination revealed a painless, palpable mass in the right scrotum. The mass was well defined and lobulated. Subsequently, a diagnosis of right epididymal tumor was made, and right high orchiectomy was performed. Hematoxylin-eosin and immunostaining revealed leiomyosarcoma of the epididymis. When a diagnosis of epididymal malignant tumor is made, the standard treatment is radical orchiectomy.

RATIONALE: Dedifferentiated liposarcoma is defined as a malignant tumor that changes its shape from a well-differentiated liposarcoma to a non-liposarcomatous form. Most paratesticular liposarcomas manifest as an inguinal, painless, slow-growing mass. The standard treatment is extensive surgical excision, radiotherapy being proposed for cases with positive margins, those with recurrence, or in cases of the existence of unfavorable prognostic factors. PATIENT CONCERNS: We present the case of a young patient diagnosed initially with left hydrocele, which after 2 years proved to mask a differentiated liposarcoma of the spermatic cord. The initial clinical manifestations were represented by the increase in volume of the left groin-scrotal region and pain at this level. DIAGNOSIS: Microscopic examination in hematoxylin-eosin staining highlighted the presence of lipoblasts and fibroblasts in association with areas of hemorrhage and tumor necrosis. The performed immunohistochemical tests confirmed the diagnosis of dedifferentiated liposarcoma. To support and confirm the presence of the mouse double minute 2 homolog gene mutation, chromogenic in situ hybridization analysis was performed. INTERVENTIONS: The initial treatment was the surgical one. After 2 weeks, the patient received zolendronic acid for hypercalcemia which was caused by the osseous metastasis. OUTCOMES: The patient died secondary to acute renal failure caused by hypercalcemia despite the treatment received. LESSONS: This case underlines the importance of both the correct management of oncological patients, as well as immunohistochemical and genetic tests in the identification of prognostic factors, with the ultimate goal of administering an appropriate oncological treatment.
