Inguinal synovial sarcoma revealed by a limb swelling: A case report

INTRODUCTION AND IMPORTANCE

Synovial sarcoma is a malignant soft tissue tumor typically found near joints; its occurrence in the inguinal region is very rare.

CASE PRESENTATION

We report a 23-years-old who presented with lower limb swelling. Imaging studies revealed a tumor in the groin area, compressing the femoral vein. A trucut biopsy concluded a synovial sarcoma. A complete resection was performed and the patient had adjuvant radiotherapy and chemotherapy with no evidence of reccurrence at 2-years follow-up.

CLINICAL DISCUSSION

Synovial sarcoma accounts for approximately 8 to 10 % of all soft tissue sarcomas. It is predominantly localized near the large joints in the limbs, with the inguinal location being extremely rare. Clinical diagnosis of the mass can sometimes be challenging. A needle biopsy, followed by histological analysis, is necessary to establish the diagnosis. MRI is considered the gold standard radiological examination for local staging of the tumor. The main treatment approach for synovial sarcoma is wide-margin resection, involving en-bloc resection of the tumor with clear margins. Vascular resection and reconstruction should be considered for involved vessels. Some authors argue that resection alone is sufficient for treating primary synovial sarcoma. However, adjuvant chemotherapy may be effective in cases where surgery quality is poor, making it a non-standard treatment. Others have highlighted the potential benefits of adjuvant radiotherapy, particularly in high-grade tumors.

CONCLUSION

Surgical excision remains the mainstay of treatment. Therefore, it is necessary to be aware of the different clinical presentations, which can sometimes be unusual.

Inguinal endometriosis: A systematic review

Inguinal endometriosis is a very rare entity with uncertain pathophysiology, that poses several diagnostic and therapeutic challenges. This study aimed to summarize published literature on the diagnosis and treatment of this condition. Thus, a systematic literature search was conducted in PubMed/MEDLINE, Scopus and the Cochrane Library. An effort was made to numerically analyze all parameters included in case reports and retrospective analyses, as well. The typical and atypical features of this condition, investigations used, type of treatment and histopathology were recorded. More specifications about the surgical treatment, such as operations previously performed, type of surgery and treatment after surgery have been acknowledged. Other sites of endometriosis, the presence of pelvic endometriosis and the follow-up and recurrence have been also documented. Overall, the search yielded 61 eligible studies including 133 cases of inguinal endometriosis. The typical clinical presentation includes a unilateral inguinal mass, with or without catamenial pain. Transabdominal or transvaginal ultrasound was typically used as the first line method of diagnosis. Groin incision and exploratory surgery was the treatment indicated by the majority of the authors, while excision of part of the round ligament was reported in about half of the cases. Chemotherapy and radiotherapy were initiated in cases of coexisting endometriosis-related neoplasia. Inguinal recurrence or malignant transformation was rarely reported. The treatment of inguinal endometriosis is surgical and a long-term follow-up is needed. More research is needed on the effectiveness of suppressive hormonal therapy, recurrence rate and its relationship with endometriosis-associated malignancies.

Benign symmetric lipomatosis (Madelung’s disease) with concomitant incarcerated femoral hernia: A case report

BACKGROUND

Benign symmetric lipomatosis (BSL) was first described by Brodie in 1846 and defined as Madelung’s disease by Madelung in 1888. At present, about 400 cases have been reported worldwide. Across these cases, surgical resection remains the recommended treatment. Here we report a case of neck BSL with concomitant thick fatty deposit in the inguinal region, which concealed the signs of a right incarcerated femoral hernia.

CASE SUMMARY

A 69-year-old male patient was admitted to our hospital with “abdominal pain, abdominal distension, nausea-vomiting and difficult defecation for half a month”. Moreover, he had a mass in the right inguinal region for more than 10 years. An egg-sized neck mass also developed 15 years ago and had developed into a full neck enlargement 1 year later. In addition, the patient had a history of heavy alcohol consumption for more than 40 years. With the aid of computerized tomography scan, the patient was diagnosed with BSL and a low intestinal mechanical obstruction caused by a right inguinal incarcerated hernia. Under general anesthesia, right inguinal incarcerated femoral hernia loosening and tension-free hernia repair was performed. However, this patient did not receive BSL resection. After a 1-year follow-up, no recurrence of the right inguinal femoral hernia was found. Moreover, no increase in fat accumulation was found in the neck or other areas.

CONCLUSION

Secretive intraperitoneal fat increase may be difficult to detect, but a conservative treatment strategy can be adopted as long as it does not significantly affect the quality-of-life.

Three-dimensional visualization and measurement of myopectineal orifice in non-inguinal hernia patients

PURPOSE

The myopectineal orifice (MPO) is a weak area at lower part of the anterior abdominal wall that directly determines the mesh size required in inguinal hernia repair. However, MPO data have mainly been acquired from measurements of cadavers or anesthetized patients. Furthermore, there are very few reports on the measurement of the MPO in Chinese patients. The present study aimed to use three-dimensional visualization technology to measure the MPO in live non-anesthetized Chinese patients, and to use this information to indicate the appropriate mesh size required for inguinal hernia repair.

METHODS

In this study, we used the parameters of the MPO and the pelvis that were measured in 40 patients with peripheral arterial disease of the lower limb arteries (80 inguinal regions) using Medraw software (Image Medraw Technology Co., Ltd., China).

RESULTS

The result showed that the average width and height of the MPO were 5.71 ± 0.99 cm and 4.96 ± 0.69 cm, respectively (5.22 ± 0.77 cm and 5.13 ± 0.63 cm in males, and 6.20 ± 0.95 cm and 4.80 ± 0.71 cm in females). The average projected area of the MPO was 16.06 ± 4.37 cm² on the left, and 15.61 ± 4.10 cm² on the right (P > 0.05).

CONCLUSION

Three-dimensional visualization was used to measure the area, width, and height of the MPO in living non-anesthetized Chinese patients. MPO area was correlated with age, but not with pelvic parameters.

Case report of Wolfe grafting for the management of bilateral cicatricial eyelid ectropion following severe burn injuries

Introduction

Eye lid reconstruction followed by severe, extensive body and facial burns represents a surgical challenge due to difficulties to obtain proper, healthy skin graft, tissue ischemia and necrosis.

Presentation of case

We present a reconstructive lid surgery of cicatricial bilateral lower eyelid ectropion in a case of 31-year-old man who sustained thermal injuries, affecting more than 60% of total body surface area, causing severe, deep dermal burns. Reconstruction was made using the technique of skin cantus-to-cantus incision, contracture release, orbicularis liberation and lid elevation; and oversizing free full-thickness skin graft (FTSG) (Wolfe technique) from the left inguinal region, as the only healthy skin on the entire body surface. Residual lower left lid laxity was addressed by pentagonal wedge resection, not interrupting marginal arcade vessels, thus minimizing ischemia.

Discussion

Method of choice of the graft type has been much debated question; however, significantly less reoccurrence rate of ectropion was observed using FTSG. Time of grafting should be balanced to avoid excess granulation and, thus scaring caused by delayed grafting time, or poor graft adherence caused by premature grafting. An interruption of the marginal arcade vessels should not be performed due to already severe ischemic process and increased risk for lid necrosis.

Conclusion

Major issues when addressing cicatricial ectropion followed by severe burns are: right donor site selection, appropriate graft thickness with the least possible disturbance of the affected place vascularisation, followed by immediate grafting after debridement of scaring and unhealthy tissue, with generous preservation of the orbicularis muscle.

A metastasized hepatocellular carcinoma in the capsule of an undescended testis in the right inguinal area: report of a rare case

Background

Hepatocellular Carcinoma (HCC) is the most common primary carcinoma of the liver, which mainly metastasizes through the portal vein system.

Case presentation

Here, we report an extremely rare case in which HCC metastasized to the capsule of an undescended testis in the right inguinal area of the patient. A tumor approximately 8.8 × 7.0 cm in size was found in the patient’s liver during a health check-up. Initially, it was considered a metastatic tumor because the patient was found to have cryptorchidism, which had been left untreated before he presented to our hospital. The patient underwent a radical orchiectomy via inguinal approach, and the resected testis in the right inguinal region was examined via microscopy. The cancer cells were arranged in nests and showed abundant red or clear cytoplasm and marked nuclear atypia. Immunohistochemical staining showed that the tumor cells were positive for CK, CK8/18, AFP, hepatocyte, GCP3, but negative for PLAP, CD10, CD30, CD34, and vimentin.

Conclusion

According to these findings, the tumor in the inguinal region was considered a metastatic HCC arising from the liver, rather than a seminoma that had originated in the undescended testis. We suggest that during the diagnosis of malignancies, metastatic tumors should always be considered in the differential diagnosis even if the original presentation is at rare metastatic sites or concurrent with other disease(s).

Giant Condyloma Acuminata of the Inguinal Region

A 70-year-old male presented with a progressively increasing polypoidal lesion in the right inguinal region since last 10 years. He had no anal or penile lesion. Excision biopsy was done under spinal anaesthesia. Histopathology showed it to be a giant condyloma acuminata. We report this case due to its large size and its location in inguinal region without pre-existing anal or rectal lesion.

Pseudomamma of the inguinal region in a female patient: A case report

INTRODUCTION

Supernumerary breasts are relative common benign congenital anomalies. General population occurrence rates vary up to 6% according to ethnicity and gender. Higher incidence is recorded in Asian individuals, especially Japanese. Embryonic breast development of the mammary ridge (milk line) is explained and supernumerary breast tissue resulting from involution failure of any portion of the embryonic mammary folds is described.

PRESENTATION OF CASE

We report a case of supernumerary breast (pseudomamma) in a female occupying her right inguinal region that was treated in the breast unit of our hospital. Differential diagnosis, imaging methods, operative approach, surgical treatment and histological verification are specified.

DISCUSSION

Classification system for supernumerary breast tissue is presented, high risk population is identified and congenital malformations linked to it are outlined. Evaluation of diagnostic workup and limitations are stated. Cancerous degeneration and justification for surgical removal of the accessory gland is discussed.

CONCLUSION

Differential diagnosis of lesions along the milk line should always be inclusive of developmental abnormalities such as any type of supernumerary breast, often overlooked due to small size, although carrying a malignant potential equal to normally positioned breasts. Surgical correction is a sensible approach, often encouraged by the patients. Additional evaluation is recommended due to the frequent accompanying urinary tract and cardiac anomalies.
