背景技术血管球瘤是罕见的,良性,软组织病变,通常发生在手中,但是它们可以发生在身体的其他部位,比如大腿。大多数时候,外血管球瘤难以诊断,症状可以持续很长时间。通常的临床表现包括疼痛,肿瘤部位的压痛,对感冒过敏.病例报告我们报告了一名39岁男子的大腿近端GT,其左大腿疼痛多年没有明显的肿块,没有明确的诊断。他的疼痛和感觉过敏因跑步而加剧。患者最初是通过超声成像诊断的,揭示了一个回合,固体,低回声,均匀的质量在左大腿上。增强磁共振成像(MRI)显示,张肌筋膜上有明确的肌内病变。通过超声引导进行经皮活检,然后切除活检和立即缓解疼痛。结论大腿血管球瘤是一种罕见的肿瘤,尤其是在大腿近端;它们很难诊断,并且与发病率有关。可以通过系统的方法和简单的调查进行诊断,例如通过超声检查。经皮活检可以帮助制定管理计划,如果病变可疑,必须考虑恶性肿瘤。如果切除不完整或无法识别同步卫星病变,症状可能会持续;因此,应考虑有症状的神经瘤。
BACKGROUND Glomus tumors are rare, benign, soft-tissue lesions, usually occurring in the hand, but they can occur in other regions of the body, such as the thigh. Most of the time, extradigital glomus tumors are difficult to diagnose, and symptoms can persist for a long time. The usual clinical presentations consist of pain, tenderness at the site of the tumor, and hypersensitivity to cold.
CASE REPORT We report a
case of a GT of the proximal thigh in a 39-year-old man with left thigh pain without palpable mass for several years, without clear diagnosis. He had pain and hyperesthesia exacerbated by running. The patient was diagnosed initially by ultrasound imaging, which revealed a round, solid, hypoechoic, homogeneous mass in the left upper thigh. Magnetic resonance imaging (MRI) with contrast showed a well-defined intramuscular lesion in the tensor fascia lata. A percutaneous biopsy was done through ultrasound guidance, followed by excisional biopsy and immediate pain relief. CONCLUSIONS Glomus tumors of the thigh are a rare neoplasm, especially in the proximal thigh; they are difficult to diagnose and are associated with morbidity. Diagnosis can be made through a systematic approach and simple investigation, such as via ultrasonography. A percutaneous biopsy can help in drawing up a management plan, and malignancy must be considered if the lesion is suspicious. Symptoms can persist in
case of incomplete resection or unrecognized synchronous satellite lesions; thus, symptomatic neuroma should be considered.
