title: A very rare bilateral adrenal tumor.
abstract: We report a case of very rare adrenal tumor. A 54-year-old patient was classified as affected by bilateral adrenal incidentaloma that surprisingly, on histology resulted solitary fibrous tumors. Solitary fibrous tumor (SFT) is an uncommon mesenchymal neoplasm. Only five cases of localization of SFT in adrenal gland are reported in the literature, while the frequency of retroperitoneum localization is more frequent, about 30 cases. Immunohistochemically, SFT can be positive for CD34 antigen, vimentin, CD99, and bcl-2 and usually negative for cytokeratins, chromogranin A, NSE, neurofilaments, synoptophysin, and S-100. Surgical excision remains the main treatment in fact the recurrence is locoregional and correlated with positive margins due to incomplete excision, while distant metastases are correlated with atypical or malignant features.
