A Rare Case of an Adrenal Schwannoma

Abstract

Schwannomas are tumors of neoplastic Schwann cells generally found in peripheral nerves in the head, neck, and extremities. They do not demonstrate hormonal abnormalities, and initial symptoms are typically secondary to adjacent organ compression. These tumors are rarely found in the retroperitoneum. We present a rare finding of an adrenal schwannoma in a 75-year-old female who presented to the emergency department with right flank pain. Imaging incidentally demonstrated a 4.8 cm left adrenal mass. Ultimately, she underwent a left robotic adrenalectomy, and immunohistochemical testing confirmed the presence of an adrenal schwannoma. It is imperative to undergo adrenalectomy and immunohistochemical testing to confirm the diagnosis and rule out malignancy.

Adrenal Schwannoma: A Case Report

“…7 Therefore, schwannomas can arise in every organ or nerve except cranial nerves 1 and 2. 5 A schwannoma is a well encapsulated, benign slow growing tumor. It was first described by Verocay in 1908.…”

“…4 Histopathology and immunohistochemical staining are the gold standard in diagnosis of adrenal schwannoma. 5 Herein, we report a case of adrenal schwannoma incidentally discovered in a 43 year old female who presented with right lumbar pain. http://jmscr.igmpublication.org/home/ ISSN (e)-2347-176x ISSN (p) 2455-0450 DOI: https://dx.doi.org/10.18535/jmscr/v11i3.21…”

An incidental large adrenal schwannoma: A case report

“…These typically benign tumors are most often found in the head, neck, and limbs, and, rarely, in the retroperitoneal space [1] . In the adrenal gland, schwannomas make up less than one percent of adrenal tumors [2] , with, as of 2022, approximately 60 cases having been reported in the literature. Patients usually present with nonspecific mild symptoms such as persistent abdominal discomfort or nausea and vomiting secondary to mass effect on adjacent organs, leading to delayed presentation and extensive tumor growth.…”
