RESUMO
INTRODUCTION AND SIGNIFICANCE: Ganglion cysts in the thigh area are uncommon, typically occurring in the wrist and ankle. These cysts are usually painless but may compress nearby structures, causing discomfort. Ultrasound is a valuable tool to differentiate ganglion cysts from hematomas and lipomas. It also helps identify the fluid-filled cyst walls. Treatment typically involves surgical removal, with complete resection being the goal. CASE PRESENTATION: We present a case of a woman who experienced a gradual increase in size of a lump in her groin area. The lump was later diagnosed and completely removed. Histological analysis revealed the presence of a ganglion cyst. CLINICAL DISCUSSION: Clinical examination is crucial for diagnosing superficial ganglion cysts. It allows us to assess their separation from the skin and connection to deeper structures. It's important to consider ganglion cysts as part of the differential diagnosis for cystic lesions in the groin area during routine medical practice. This can help avoid unnecessary and expensive tests like MRI scans in some cases. CONCLUSION: Developing a thorough differential diagnosis for uncommon lesions in specific anatomical areas is essential in clinical practice. This aids in choosing appropriate diagnostic methods and surgical intervention, if necessary, to prevent recurrence of the condition.
