Introduction:: Gangliocytic paraganglioma is an extremely rare tumor that is composed of epithelioid, ganglion, and spindle cells. It has a predilection site in the duodenum, especially the periampullary region. The clinical course is usually benign, but a few cases of metastasis to lymph nodes or distant sites have been noted. Several case reports or small series reviews of gangliocytic paraganglioma have been published, but so far, cecal gangliocytic paraganglioma has not been described. Case description: A 61-year-old man underwent an abdominal Computed Tomography (CT) scan for known GB stones, which revealed an incidental cecal mass. The patient underwent wedge resection of the cecum for diagnostic and therapeutic purposes. Histopathological examination of the cecal mass identified a gangliocytic paraganglioma. There was no evidence of metastasis in the dissected regional lymph nodes. No additional treatment, such as adjuvant chemotherapy or radiotherapy, was administered, and the patient underwent regular follow-up without any complications. Conclusion: The most common radiologic finding in gangliocytic paraganglioma is a circumscribed, enhancing subepithelial mass. Herein, we report an uncommon case of cecal-origin gangliocytic paraganglioma. With knowledge of the radiologic and histologic characteristics of gangliocytic paraganglioma, appropriate management can be provided without unnecessary radical resection.
Introduction: Angiolipoleiomyoma (ALLM) is a rare hamartomatous tumor of mesenchymal origin composed of smooth muscle, mature adipose tissue, and blood vessels in various proportions. Because of its histologic similarity to renal angiomyolipoma (AML), it is also called uterine angiomyolipoma. Preoperative diagnosis of uterine ALLM is very challenging due to its uncommon incidence and absence of established characteristic imaging findings. Case description: A 50-year-old multiparous female patient visited our institution for gynecologic screening. Transvaginal sonography (TVS), Abdominopelvic computed tomography (CT), and pelvic magnetic resonance imaging (MRI) revealed large well-defined masses involving the posterior uterine wall with rectal indentation. The patient underwent a total abdominal hysterectomy for this tumor and the histopathological diagnosis was uterine ALLM. Conclusion: This report would contribute to understanding and establishing the radiologic findings of the uterine ALLM. Considering the benign characteristics and favorable prognosis of this rare tumor, familiarity with its imaging findings by radiologists will guide clinicians in better patient management and prevention of unnecessary radical surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
