We evaluated the clinical characteristics associated with epithelioid AML and the prognosis of epithelioid AML. METHODS Medical records of 231 patients consist of 204 patients with epithelioid AML and 27 patients with conventional AML were reviewed. Computed tomography (CT) was performed in all patients before pathological confirmation of the disease. Tumor size and Hounsfiled unit (HU) were measured on pre-contrast and arterial phase of CT. Pathologic specimens were reviewed by pathologists who are specialized in urologic pathology. Variables associated with epithelioid AML were assessed using multivariate analysis. RESULTS Patients with epithelioid AML were younger (41.2 years vs. 49.1 years, p = 0.001) than patients with conventional AML. Male patients were more common in patients with epithelioid AML (56% vs. 29%, p = 0.005). Tumor size was larger in patients with epithelioid AML compared to conventional AML (7.5cm vs. 4.2cm, p < 0.001). Difference in HU between pre-contrast and arterial phase was significant lower in epithelioid AML group (46.6 vs. 65.9 HU, p=0.022). In multivariable logistic regression analysis, younger age (p = 0.024) and male gender (p = 0.024) were significantly associated with epithelioid AML. Among 27 patients with epithelioid AML, distant metastasis was observed in 8 (29.7%) patients and these patients had larger tumor compared with the other 19 patients (10.8cm vs. 6.1cm, p = 0.014). Three patients with metastasis were expired in 10 days, 47 months and 118 months after the diagnosis of the disease. CONCLUSIONS Patients with epithelioid AML should be carefully followed-up because of malignancy potential. We should not overlook the probability of epithelioid AML, especially in young male patients with larger tumor size. © 2016FiguresReferencesRelatedDetails Volume 195Issue 4SApril 2016Page: e962 Advertisement Copyright & Permissions© 2016MetricsAuthor Information Jaeyoon Jung More articles by this author Junghyun Shin More articles by this author Jae Hyeon Han More articles by this author Se Young Choi More articles by this author Sangjun Yoo More articles by this author Sungwoo Hong More articles by this author Hyung Jee Kim More articles by this author Taekmin Kwon More articles by this author Kyung Hyun Moon More articles by this author Dalsan You More articles by this author In Gab Jeong More articles by this author Choung-Soo Kim More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
