Bilateral Epstein-Barr virus-associated adrenal leiomyomas in a child without an established immunodeficiency

EBV-Associated Smooth Muscle Tumors With Autoimmune Hemolytic Anemia and Hepatitis B Infection: Report of a Previously Undescribed Neoplasm With Review

Epstein-Barr virus-associated smooth muscle tumor (EBV-SMT) is rare in adults. The presence of intratumoral T lymphocytes and primitive rounded cells characterized this neoplasm. We report a 24-year-old Chinese man who developed EBV-SMT in the right adrenal gland with hepatitis B infection and autoimmune hemolytic anemia without a history of HIV infection, primary immune deficiency, organ transplantation, or malignant tumor. This patient had an unknown immunodeficient state. EBV-SMTs are commonly located in the liver, lung, and gastrointestinal tract but rarely in the adrenal gland. We reviewed 10 reported literature on EBV-SMT in the adrenal gland. It is imperative to distinguish EBV-SMT from conventional somatic smooth muscle tumors. The discovery of EBV-SMT forces the clinician to conduct a thorough evaluation of immune function and immune status surveillance, and these patients are vulnerable to subsequent malignant tumors.

Review of the Literature on Leiomyoma and Leiomyosarcoma of the Adrenal Gland: A Systematic Analysis of Case Reports

BACKGROUND/AIM

To date few cases of smooth muscle-derived tumors of the adrenal gland have been reported and their treatment remains a medical challenge. The aim of this manuscript was to systematically review the literature and present the tumor characteristics and their management in order to provide a standardized approach to their diagnosis and management.

MATERIALS AND METHODS

We searched five databases (PubMed, Scopus, Elsevier, ResearchGate, Google scholar) for relevant articles published until March 2020.

RESULTS

Twenty-two cases of adrenal leiomyoma, four cases of adrenal smooth muscle tumor and forty-five cases of adrenal leiomyosarcoma were included.

CONCLUSION

We present the demographic, clinical, radiological, pathological and oncological characteristics and prognosis of tumors of the adrenal gland arising from smooth muscle cells, as well as describe the common clinical investigations and therapeutic modalities that have been reported as part of their management.
