“…In 2014, Untch and colleagues [3] reviewed 11 histopathologically-proved adrenal collision tumors described in literature. In the last five years other 14 case reports of adrenal collision tumors have been published [3,[32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51]. The 25 cases are summarized in Table 1.…”

The adrenal glands are one of the most prevalent sites for metastases from various malignancies and metastases are indeed the most frequent malignant tumors of the adrenals. The identification of incidental adrenal lesions, of which a high proportion are metastases, have increased since surveillance protocols in cancer treated patients were widely introduced. More sensitive and reliable methods of diagnostic imaging leads to earlier detection of adrenal metastases. If there are no signs and symptoms of disseminated malignant disease, it is essential to differentiate adrenal lesions. CT imaging diagnostics and MRI play the main role in differential diagnosis. Adrenal biopsy is not recommended and is of limited diagnostic value. Appropriate selection of patients with adrenal metastases for curative treatment is a great challenge. Hormonal evaluation should be performed prior to treatment. Adrenalectomy seems to be a reasonable treatment for isolated adrenal metastasis in suitable patients. Minimally invasive laparoscopic adrenalectomy is as effective as the open approach with proven reduction in postoperative pain, morbidity and length of stay. Nonsurgical treatment such as stereotactic body radiation therapy (SBRT), radiotherapy with CyberKnife, percutaneous radiofrequency ablation, percutaneous microwave ablation, radiofrequency plus chemoembolization combined, have been reported with curative and palliative intent and have shown varied results.

“…Incidental adrenal lesions are common in patients with primary RCC, which may be difficult to differentiate from adrenal adenomas due to signal dropout on chemical shift MRI [80]. Most adrenal adenomas are nonfunctional; however, the presence of contralateral adrenal atrophy may suggest otherwise [81].…”

Collision and composite tumors; radiologic and pathologic correlation

et al. 2017

View full text Add to dashboard Cite

The terms composite and collision tumors have been used interchangeably throughout radiological literature. Both composite and collision tumors involve two morphologically and immunohistochemically distinct neoplasms coexisting within a single organ. However, collision tumors lack the histological cellular intermingling seen in composite tumors. Composite tumors often arise from a common driver mutation that induces a divergent histology from a common neoplastic source while collision tumors may arise from coincidental neoplastic change. The purpose of this review is to provide an overview of abdominal composite and collision tumors by discussing hallmark radiographic and pathological presentations of rare hepatic, renal, and adrenal case studies. A better understanding of the presentation of each lesion is imperative for proper recognition, diagnosis, and management of these unique tumor presentations.
