Adrenal Ganglioneuroblastoma in an Adult: A Rare Case Report

Adrenal ganglioneuroblastoma with metastasis near the renal hilum in an adult female: A case report and review of the literature

Ganglioneuroblastoma (GNB), predominantly observed in children, is an uncommon malignant tumor in adults, with established treatment protocols notably lacking. The present study details the case of a 20-year-old woman who presented with a left adrenal gland mass, identified during a physical examination. Additionally, an unidentified mass was noted near the renal hilum in the preoperative evaluation. Following thorough preoperative preparation, both the primary adrenal gland mass and the renal hilar mass were surgically removed. The procedure concluded successfully. Pathological analysis confirmed that the left adrenal mass was a GNB and identified the renal hilar mass as a metastatic extension. Postoperative examination revealed a new formation at the original surgical site, later verified as a postoperative scar. Through the publication of a case report and extensive literature review, the present study aims to enhance our understanding of this condition, providing valuable diagnostic, therapeutic and post-recovery references for this rare adult disease.

A needle in the haystack: An unusual case presentation of ganglioneuroblastoma at a tertiary care center in Coastal Karnataka

Key Clinical Message

This case report highlights the importance of recognizing and accurately diagnosing ganglioneuroblastoma, an uncommon variant of neuroblastic tumors in children. Ganglioneuroblastomas have diverse clinical and morphological presentations, and histopathological examination is paramount in guiding treatment decisions, especially in cases with ambiguous symptoms. Early detection is crucial, as the prognosis varies significantly based on the subtype and the presence of metastatic disease. Clinicians should maintain a high index of suspicion and utilize radiological examinations to promptly identify and treat these tumors.

Abstract

Children are frequently affected by neuroblastic tumors, which grow from the sympathoadrenal lineage of the neural crest during its development. However, intermixed ganglioneuroblastomas are far less common within the same tumor spectrum, the diagnosis of which could become challenging amidst an unusual presentation. In our case report, we present a 4-year-old boy who had complaints of fever and difficulty in walking, with a supra-renal mass on ultrasound, which was diagnosed as ganglioneuroblastoma-intermixed type on histopathological examination. This report aims to contribute to the understanding of the diverse clinical and morphological spectrum of ganglioneuroblastomas and the importance of multidisciplinary collaboration and histopathological examination to enhance decision-making in such ambiguous scenarios.

Metabolic syndrome and thyroid Cancer: risk, prognosis, and mechanism

The increasing incidence of thyroid cancer (TC) cannot be fully explained by overdiagnosis. Metabolic syndrome (Met S) is highly prevalent due to the modern lifestyle, which can lead to the development of tumors. This review expounds on the relationship between Met S and TC risk, prognosis and its possible biological mechanism. Met S and its components were associated with an increased risk and aggressiveness of TC, and there were gender differences in most studies. Abnormal metabolism places the body in a state of chronic inflammation for a long time, and thyroid-stimulating hormones may initiate tumorigenesis. Insulin resistance has a central role assisted by adipokines, angiotensin II, and estrogen. Together, these factors contribute to the progression of TC. Therefore, direct predictors of metabolic disorders (e.g., central obesity, insulin resistance and apolipoprotein levels) are expected to become new markers for diagnosis and prognosis. cAMP, insulin-like growth factor axis, angiotensin II, and AMPK-related signaling pathways could provide new targets for TC treatment.

Adrenal Ganglioneuroblastoma of Adult Onset: A Literature Review

Ganglioneuroblastomas (GNBs) are a rare subtype of neoplastic tumors that arise from the autonomic nervous system and contain both mature gangliocytes and immature neuroblasts. The primary age group affected by GNBs is the pediatric population, with less than 50 cases of adult GNBs existing in the literature. To the authors' best knowledge, only 21 cases of GNBs arising in the adrenal glands of adults have been reported. Herein we present a literature review examining the symptoms, treatment type, age, and sex of adults, and the presence of tumor metastases and calcification from the 21 cases reported in the literature.

Retroperitoneal ganglioneuroblastoma with postoperative stress ulcer perforation in an adolescent: A case report and review of the literature

Ganglioneuroblastoma (GNB) is a condition belonging to the neuroblastoma family. It is a transitional tumor consisting of a mixture of mature ganglioneuromas and malignant neuroblastomas. Its biological behavior is intermediate between benign and malignant, with a risk of recurrence and metastasis. It usually occurs in pediatric patients aged <10 years, particularly between the ages of 1 and 2 years, but may also occur in adolescents or adults. The present study reported on the clinical management of a case of postoperative stress ulcer with perforation in a 17-year-old female patient with retroperitoneal GNB and provided a review of the literature on retroperitoneal GNB in adolescents and adults.

A rare case of adrenal ganglioneuroblastoma-intermixed in an adult and a review of literature

Peripheral neuroblastic tumors are extremely rare in the adult with less just over 20 cases involving adrenal gland described in the literature. We reported herewith the case of a 22-year-old young male who presented with epigastric pain and diarrhea. Imaging studies documented a 3.5cm x 3cm x 4cm solid well-circumscribed right adrenal mass, of heterogeneous structure and with fine calcifications. The lesion turned negative at MIBG scintigraphy. A right robotic-assisted adrenalectomy was performed leading to complete excision of the lesion without complications. Histology was consistent with intermixed stroma-rich ganglioneuroblastoma. A wait-and-see strategy was considered adequate. Two years after diagnosis patient is alive disease-free. Although the definitive diagnosis of a peripheral neuroblastic tumor is obtained after histopathological analysis, CT, and MRI are helpful to further characterize masses and useful in pretreatment risk stratification. Clinicians should be aware of the possibility of GNB development in adult population and its malignant potential.

Adrenal cortical carcinoma: pathology, genomics, prognosis, imaging features, and mimics with impact on management

Adrenocortical carcinoma (ACC) is a rare tumor with a poor prognosis. Most tumors are either metastatic or locally invasive at the time of diagnosis. Differentiation between ACC and other adrenal masses depends on clinical, biochemical, and imaging factors. This review will discuss the genetics, pathological, and imaging feature of ACC.

Posterior mediastinal ganglioneuroblastoma in an adolescent: A case report and review

Ganglioneuroblastoma is an uncommon malignant tumor of the sympathetic nervous system, which is considered a disease of children with the majority of cases in patients less than four years old and it rarely occurs in adults. We encountered a very unusual case of a posterior mediastinal ganglioneuroblastoma that developed in a 17-year-old male adolescent who underwent successful excision of the mediastinal mass and remained stable postoperatively. However, he developed lumbago one year after the surgery. Radiographic findings revealed osteolytic lesions in the lumbar vertebra and histological analysis confirmed bone metastasis of ganglioneuroblastoma. Here, we report the clinical course and present a review of the literature regarding adolescent and adult onset mediastinal ganglioneuroblastoma.
