Imaging Findings of Primary Malignant Melanoma of the Esophagus: A Case Report

原發性食道黑色素瘤的影像發現:病例報告

摘要


食道的原發性黑色素瘤在臨床上是不常見的,但卻是極惡性且有不好的預後。我們在這裡報告一個少見的原發性食道黑色素瘤且在右頸部有淋巴結的轉移,並且討論影像學的發現,包括了鋇劑食道攝影,電腦斷層攝影,超音波及正子斷層攝影。當在影像學上有特別的發現像是類瘜肉狀,腔室內的,非阻塞性的腫塊時,一些診斷像是梭狀上皮細胞癌,橫紋肌肉瘤,淋巴瘤都需作第一考慮。但是原發性食道黑色素瘤總是需要納入鑑別診斷雖然它是很罕見的。

Primary melanoma of the esophagus is not frequently encountered clinically but rather high degree malignant that have a poor prognosis. Here we report an uncommon case of primary melanoma of the esophagus with nodal metastasis over the right neck and discuss its radiographic findings, including esophagogram, contrast-enhanced computed tomography (CECT), sonography of neck and positron emission tomography (PET). When characteristic findings as polypoid, intraluminal, and nonobstructive masses are present on image studies, some diagnosis such as spindle cell carcinoma, leiomyosarcoma and lymphoma should be considered first. However, the diagnosis of primary esophageal melanoma always should be kept in mind despite of its rarity.
