“…On histological examination, most specimen was diagnosed as well-differentiated liposarcomas, comprised of 7 cases. 5,7,8,10–12 The large tumors' weight ranged widely from 1.26 kg in the presented case up to 42 kg. 9 R0 resection margins are documented in only 2 cases after primary surgery.…”

“…Side of the body was almost evenly distributed with 5 right-sided 6–8,10 and 4 left-sided 9–13 manifestations. Three cases appeared as an incarcerated hernia, 11,14 of note one tumor appeared as a reducible hernia 8 ; the others were not documented. In 5 cases a computed tomography scan was performed preoperatively 6,9–11,13 ; notably none of them was conducted due to the combined suspicion of an inguinal hernia and a retroperitoneal tumor.…”

Background and Objectives:The goal of the study was to evaluate retroperitoneal sarcomas with continuous growth into the scrotum through the inguinal canal with regard to diagnostic approach, surgical treatment, and outcome. The analysis is based on a comprehensively documented case and a complete systematic review of published literature. Potential pitfalls are highlighted.Methods:We describe the case of a 57-year-old male Caucasian who presented with a swelling in the right groin. Suspecting a scrotal hernia, transabdominal preperitoneal plasty surgery was planned but intraoperatively a large retroperitoneal mass was revealed. After computed tomography scan and magnetic resonance imaging, a complete resection of the tumor was performed. Ten previously published cases describing the same pathology were retrieved from the PubMed database and analyzed systematically in a complete literature review.Results:Histology showed a well-differentiated liposarcoma with tumor-free resection margins. Twenty-two months postoperatively, the patient is in complete clinical remission.Conclusion:Preoperative clinical suspicion of retroperitoneal involvement is paramount for developing of a surgical strategy and in unclear cases demands extended preoperative diagnostic workup. Following the appropriate patient management is crucial to prognosis.

“…La exploración física demuestra una masa sólida irregular con transiluminación negativa. El diagnóstico preoperatorio no es común, lo habitual es un hallazgo incidental intraoperatorio en el contexto de una cirugía realizada al suponer alguna de las patologías que se incluyen en el diagnóstico diferencial; en este caso clínico el diagnóstico fue en el curso de una cirugía urgente realizada por sospecha de hernia inguinal incarcerada [23][24][25] . Pero en caso de sospecha preoperatoria las pruebas complementarias indicadas serían la TC o la RM.…”

Liposarcoma of the spermatic cord mimicking an incarcerated inguinal hernia Introduction: Paratesticular tumors represent 7%-10% of intraescrotal masses. Sarcomas account for 90% of malignant lesions of the spermatic cord and of these approximately 3%-7% are liposarcomas. Clinical case: This is the case of a 45 year old male who consulted in the emergency department for a non-reducible right inguino-scrotal mass and was diagnosed with an incarcerated inguinal hernia. Emergency surgery was performed which revealed a large lipomatous tumor, originating from the spermatic cord. Orchiectomy and hernioplasty were performed. Histopathology revealed a well-differentiated liposarcoma of the spermatic cord. Later extension study was conducted, without distant affectation, and did not require adjuvant treatment. Today, after two years of monitoring has been no recurrence. Discussion: Only about 200 cases have been previously reported in the literature and only 61 of these were presented mimicking an incarcerated inguinal hernia. Due to the low incidence of this disease it is difficult to know the natural history and draw conclusions on the results of treatment, which so far remains the radical orchiectomy with wide local excision of the tissue. The role of radiotherapy and chemotherapy is still controversial

“…Previously, only a few published case reports of inguinal hernia were available, and they discussed an LPS protruding from the retroperitoneum. [4][5][6][7][8][9]12,13 Although 6 is a small number for reliable statistical analysis, we showed that RLPS protruding into the inguinal canal has poor prognosis compared with inguinoscrotal LPS.…”

“…Only a few case reports describe RLPS presenting as an inguinal hernia. [4][5][6][7][8][9] Sometimes, a protruding mass in the inguinal region is the only symptom, resulting in a misdiagnosis of ordinary inguinal hernia.…”

Background:This study was designed to analyze differences between retroperitoneal liposarcoma (RLPS) extending into the inguinal canal and inguinoscrotal liposarcoma. Methods:We retrospectively reviewed the records for patients who were managed for inguinal liposarcoma at Samsung Medical Center, a tertiary hospital, between January 1998 and December 2016. Patient data on demographics, tumour location, surgery, adjuvant therapy, histology, recurrence and death were collected. We used Mann-Whitney, Fisher exact and Kaplan-Meier log-rank tests to analyze differences between groups.Results: Seven of 179 (3.9%) patients with abdominal liposarcoma had inguinoscrotal liposarcoma, and 6 of 168 (3.6%) patients with RLPS had extension to the inguinal canal. No differences were observed between groups in sex (p > 0.99), mean age (49.7 ± 6.4 yr v. 52.1 ± 12.5 yr, p = 0.37), laterality (p > 0.99) or scrotal involvement (40.0% v. 66.7%, p = 0.57). The RLPS group had significantly larger tumours than the inguinoscrotal group (27.9 ± 6.8 cm v. 7.8 ± 4.2 cm, p = 0.001). Postoperative complications were significantly more common in the RLPS group (n = 4, 83.3%); patients in the inguinoscrotal group experienced no postoperative complications (p = 0.021). Log-rank tests showed that the groups had no statistical differences in diseasefree survival (p = 0.94) or overall survival (p = 0.10). However, inoperable disease-free survival was significantly poorer in the RLPS group (p = 0.010). Conclusion:Although initial signs and symptoms can be similar, RLPS extending into the inguinal canal was associated with significantly higher morbidity and mortality than inguinoscrotal liposarcoma.Contexte : Cette étude visait à examiner les différences entre le liposarcome rétro-péritonéal s'étendant au canal inguinal et le liposarcome inguino-scrotal.Méthodes : Nous avons procédé à une analyse rétrospective des dossiers de patients traités pour un liposarcome inguinal au Samsung Medical Center, un hôpital de soins tertiaires, entre janvier 1998 et décembre 2016. Nous avons recueilli les données des patients en ce qui a trait aux caractéristiques démographiques, au siège de la tumeur, à la chirurgie, au traitement adjuvant, à l'histologie, à la récidive et au décès. Nous avons utilisé le test de Mann-Whitney, la méthode exacte de Fisher et les tests logarithmiques par rangs de Kaplan-Meier pour analyser les différences entre les 2 groupes.Résultats : Sept des 179 (3,9 %) patients atteints de liposarcome abdominal avaient un liposarcome inguino-scrotal, et 6 des 168 (3,6 %) patients atteints de liposarcome rétropéritonéal présentaient une extension au canal inguinal. Aucune différence n'a été observée entre les groupes pour le sexe (p > 0,99), l'âge moyen (49,7 ± 6,4 ans c. 52,1 ± 12,5 ans, p = 0,37), la latéralité (p > 0,99) ou l'atteinte scrotale (40 % c. 66,7 %, p = 0,57). La taille de la tumeur était significativement plus grande dans le groupe du liposarcome rétropéritonéal que dans celui du liposarcome inguino-scrotal (27,9 ± 6,8 cm c. 7,8 ± ...
