Well-differentiated liposarcoma of spermatic cord presenting as recurrent inguinal hernia: a case report.

Background: Well-differentiated liposarcoma arising from the paratesticular region is rare, with only a few hundred cases reported in the literature. Due to their unexpected location, these tumors are often confused for common pathologies found in the groin, including inguinal hernia, seroma, or lymphoma. Standardized diagnostic and treatment pathways have not been established for patients with paratesticular liposarcoma, thereby elevating the importance of sharing our experience. Case Description: This case describes the presentation of a 65-year-old man with a well-differentiated liposarcoma of the spermatic cord. Diagnosis was made after he underwent open herniorrhaphy to repair what was presumed to be a recurrent left inguinal hernia. Although a recommendation for formal oncologic resection and orchiectomy was made, the patient elected to proceed with watchful waiting and remains well up to last known contact. Conclusions: Paratesticular liposarcoma remains a rare clinical entity. While a few hundred cases have been reported in the literature, only a handful describe its presentation masked as an early recurrence of a groin hernia. Wide local resection along with orchiectomy and potential radiation therapy have been the mainstay of treatment. Clinicians should maintain a healthy level of suspicion for this uncommon pathology, especially in cases where patients present with early recurrence of an inguinal hernia.

Comparison of Outcomes Between Surveillance Ultrasound and Completion Lymph Node Dissection in Children and Adolescents With Sentinel Lymph Node-Positive Cutaneous Melanoma.

OBJECTIVE: To determine the impact of nodal basin ultrasound (US) surveillance versus completion lymph node dissection (CLND) in children and adolescents with sentinel lymph node (SLN) positive melanoma. BACKGROUND: Treatment for children and adolescents with melanoma are extrapolated from adult trials. However, there is increasing evidence that important clinical and biological differences exist between pediatric and adult melanoma. METHODS: Patients ≤18 years diagnosed with cutaneous melanoma between 2010 and 2020 from 14 pediatric hospitals were included. Data extracted included demographics, histopathology, nodal basin strategies, surveillance intervals, and survival information. RESULTS: Of 252 patients, 90.1% (n=227) underwent SLN biopsy (SLNB), 50.9% (n=115) had at least 1 positive node. A total of 67 patients underwent CLND with 97.0% (n=65/67) performed after a positive SLNB. In contrast, 46 total patients underwent US observation of nodal basins with 78.3% (n=36/46) of these occurring after positive SLNB. Younger patients were more likely to undergo US surveillance (median age 8.5 y) than CLND (median age 11.3 y; P =0.0103). Overall, 8.9% (n=21/235) experienced disease recurrence: 6 primary, 6 nodal, and 9 distant. There was no difference in recurrence (11.1% vs 18.8%; P =0.28) or death from disease (2.2% vs 9.7%; P =0.36) for those who underwent US versus CLND, respectively. CONCLUSIONS: Children and adolescents with cutaneous melanoma frequently have nodal metastases identified by SLN. Recurrence was more common among patients with thicker primary lesions and positive SLN. No significant differences in oncologic outcomes were observed with US surveillance and CLND following the identification of a positive SLN.

Gastric Outlet Obstruction from Stomach-Containing Groin Hernias: Case Report and a Systematic Review.

Most abdominopelvic structures can find their way to a groin hernia. However, location, and relative fixation are important for migration. Gastric outlet obstruction (GOO) from a stomach-containing groin hernia (SCOGH) is exceedingly rare. In the current report, we present a 77-year-old man who presented with GOO from SCOGH to our facility. We performed a review of the literature following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) of patients presenting with SCOGH since it was first reported in 1802. Ninety-one cases of SCOGH were identified (85 inguinal and six femoral) over the last two centuries (1802-2023). GOO from SCOGH occurred in 48% of patients in one review and 18% in our systematic analysis. Initial presentation ranged from a completely asymptomatic patient to peritonitis. Management varied from entirely conservative treatment to elective hernia repair to emergent laparotomy. Only one case of laparoscopic management was documented. Twenty-one deaths from SCOGH were reported, with most occurring in early manuscripts (1802-1896 [n = 9] and 1910-1997 [n = 10]). In the recent medical era, outcomes for patients with this rare clinical presentation are satisfactory and treatment ranging from conservative, non-operative management to surgical repair should be tailored towards patients' clinical presentation.
