“…Most of the MA-like tumors are detected incidentally by diagnostic imaging, without showing clinical findings. CT scans, ultrasound and MRI imaging do not usually further elucidate a specific image diagnosis von Willebrand disease have been found in patients with MA [6]. However, no other MA has been reported in patients with nonHodgkin lymphoma diagnosed, as in our case.…”

“…In the last 14 years only 2 cases of MA have been found among more than 100,000 biopsies reported at the Hospital Universitario Miguel Servet, Zaragoza, Spain. Some cases of MA have been described in the literature associated with hematological diseases, particularly polycythemia Vera [6,8]. There is a higher incidence of simultaneous polycythemia compared to any other renal diseases.…”

“…Vimentin positive and the rest of the immunohistochemical profile was the usual for MA. Even though, there is no specific antibody profile for MA [6,9]. For example, EMA and CK7 are absent in most MA, but some authors have reported positive results for these antibodies [5,9].…”

“…However, the current case demonstrated a clearly defined margin with diffuse calcifications, dissimilar to that observed in previous cases. This formation of diffuse calcifications may correlate with intratumoral hemorrhage (12,13). Patients with metanephric adenoma typically have a good prognosis after undergoing total nephrectomy or local resection with kidney preservation (14).…”

Abstract. Metanephric adenoma is a rare and benign renal neoplasm originating in the epithelial cells of the kidney. The tumor has a benign course and a characteristic histopathological appearance, typically exhibiting a solid and poorly-demarcated margin with rare cystic components or calcifications. However, it is often difficult to distinguish metanephric adenoma from malignant neoplasms prior to surgical resection. To the best of our knowledge, only one case of metastasis to the lymph nodes has been described in the literature thus far. The present study retrospectively analyzed one case of surgically and pathologically-confirmed atypical metanephric adenoma. Clinical and pathological analysis, as well as computed tomography scans, revealed a mass with a clearly defined margin and diffuse calcifications. The mass was subsequently resected and the patient recovered well following the procedure.

“…17 In our initial experience, MA is a heterogeneous neoplasm with different pathological and biological characteristics; similar findings include metastatic cases reported in English literature. 18,19 Theoretically, CT findings, especially enhancement, may reflect the histological composition, and the variable enhancement degree concerning MA should suggest the possibility of coexisting subtypes. Correspondingly, tumour CT attenuation values and enhancement ratios were correlated with histological subtypes.…”

Metanephric adenoma (MA) was first identified in 1979 and has been subsequently classified within the group of metanephric tumours, which comprise MAs, metanephric adenofibromas and metanephric stromal tumours. 1 The wide use of ultrasound, CT and MRI has led to an increase of incidentally discovered renal masses, including benign and malignant renal tumours. However, there are no unique and reliable radiological features for the differentiation of MA from renal cell carcinoma (RCC) and other benign renal tumours except for angioleiomyolipoma. There are no well-admitted criteria so this makes a diagnosis difficult; therefore, we performed the investigation focusing on CT imaging characteristics and corresponding pathological findings in order to establish CT diagnostic criteria of MA as the reference standard. METHODS AND MATERIALS Design and patientsThe clinical and radiological data were retrieved from archival files and were retrospectively analysed. Our institutional review board of The Second Hospital of Tianjin Medical University and Tianjin Union Medicine Center approved this study and waived the informed consent requirement. Data collected included age, gender, clinical presentation, preoperative tumour characteristics (size, location, diameter, nearness to collecting system, growth pattern etc) and final pathological findings. In total, 18 patients (9 males and 9 females; mean age, 50 years; range, 18-66 years) between
