Retroperitoneal Schwannoma

Schwannomas usually occur in adults being between the second and fifth decades, and such neoplasms are extremely rare in a pediatric population. In addition, they are not normally found in the retroperitoneal region. Here, we present a pediatric case of a retroperitoneal schwannoma in an adrenal location where the tumor was not able to be preoperatively differentiated from other benign or malign adrenal gland tumors. In our opinion, this tumor can be included in the differential diagnosis of a nonfunctioning retroperitoneal adrenal mass in children.

21 Hydroxylase Deficiency

The objective of this study was to describe a case of giant myelolipoma associated with undiagnosed congenital adrenal hyperplasia (CAH) due to 21-hydroxylase (21OH) deficiency. Five seven year-old male patient referred with abdominal ultrasound revealing a left adrenal mass. Biochemical investigation revealed hyperandrogenism and imaging exams characterized a large heterogeneous left adrenal mass with interweaving free fat tissue, compatible with the diagnosis of myelolipoma, and a 1.5 cm nodule in the right adrenal gland. Biochemical correlation has brought concerns about differential diagnosis with adrenocortical carcinoma, and surgical excision of the left adrenal mass was indicated. Anatomopathologic findings revealed a myelolipoma and multinodular hyperplasic adrenocortex. Further investigation resulted in the diagnosis of CAH due to 21OH deficiency. Concluded that CAH has been shown to be associated with adrenocortical tumors. Although rare, myelolipoma associated with CAH should be included in the differential diagnosis of adrenal gland masses. Moreover, CAH should always be ruled out in incidentally detected adrenal masses to avoid unnecessary surgical procedures.

Head and neck tumors are rare in pediatric patients but should be kept in the differential when a patient presents with a new swelling or mass. One of these tumors is a myxoma, which is an insidiously growing, benign mass originating from the mesenchyme. They most commonly arise in the myocardium but can also develop in facial structures, particularly in the maxilla and mandible. When arising in facial structures, ocular, respiratory, and digestive systems can be affected based on local invasion. Complete surgical resection is curative but can lead to significant morbidity as well. Here, we present a case of a 15-month-old toddler presenting with a paranasal mass, which was ultimately diagnosed as a maxillary myxoma. This tumor is very rare in the pediatric population, especially in the toddler age-group, reminding clinicians to broaden the differential diagnosis when a patient’s course is atypical.

The adrenal incidentaloma is a lesion of a different etiology and found incidentally in patients who underwent a diagnostic study not about the disease of this organ. Lesions can be both hormonally inactive and hormonally active, can arise from different zones of the adrenal gland or have non-specific organ affiliation, can be benign or malignant. Computed tomography characterization of these lesions, especially the differential diagnosis of benign and malignant, is extremely important for the correct diagnosis in order to provide adequate management of the patient. The article presents the key computed tomography criteria that allow radiologist to characterize the lesion most accurately and consider appropriate diagnosis.

Abstract Introduction: In an adult endocrine clinic, the majority of patients referred for evaluation of an adrenal incidentaloma are older than 30 years of age. It is important to be reminded that a patient may be diagnosed with an adrenal mass at any age but the etiology may vary depending on the age at presentation. Clinical case: An 18 year-old African American female with no significant past medical problems presented with a 2 month history of flank and abdominal pain associated with nausea and vomiting. An abdominal CT scan and a dedicated adrenal CT showed a right adrenal mass measuring 2.2 x 2.6 cm. The noncontrast Hounsfield units were 23, enhanced Hounsfield units 210, and delayed Hounsfield units 72. The calculated washout was 44%, not consistent with an adrenal adenoma. An MRI of the abdomen showed a 2.5 cm right adrenal nodule. The lesion did not demonstrate significant loss of signal between in and out of phase imaging, therefore the characteristics were not consistent with a lipid rich adenoma. Laboratory tests included an ACTH of 31 pg/mL (6-48 pg/mL), cortisol 8.7 ug/mL at 10:57 am (7-9 am 5.27-22.45 ug/mL), aldosterone 10.1 ng/dL (6-48 ng/dL), renin 2.2 ng/mL/hr (upright 0.5-4.0 ng/mL/hr), DHEA-sulfate 129 ug/dL (44-248 ug/dL), plasma free metanephrine 0.10 nmol/L (0.00-0.49 nmol/L), and plasma free normetaneprhine 0.41 nmol/L (0.00-0.89 nmol/L). The 24-hour urine norepinephrine, epinephrine, and metanephrine were all normal, however the 24-hour urine dopamine was elevated, 824 ug/24 hrs (52-480 ug/24 hrs). Subsequently, plasma dopamine, norepinephrine, and epinephrine were all within the reference range. The patient had a robotic-assisted right adrenalectomy removing a 5.7 x 3.5 x 1.7 cm gland, weighing 16.3 grams. The pathology demonstrated a ganglioneuroma within the right adrenal gland measuring 2.2 x 2.0 x 2.7 cm, negative for neuroblastoma or blastic components. Focal hemorrhage was noted, there was no tumor necrosis, and no mitotic figures were present. The tumor appeared to be encapsulated in the adrenal gland and the Ki-67 stain was negative in ganglioneuroma cells. Conclusion: Adrenal adenomas that appear as incidentalomas in young adulthood are extremely rare. Evaluating younger versus older adults found to harbor an adrenal “incidentaloma“ requires a unique approach for each age group, as the differential diagnosis varies widely. In our patient, the imaging was extremely concerning and diagnostic considerations included neuroblastoma, adrenocortical malignancy, pheochromocytoma, or ganglioneuroma. Adrenal ganglioneuromas are most frequently diagnosed in fourth and fifth decades of life. In younger adults ganglioneuromas are usually found in the retroperitoneum and posterior mediastinum. For our patient, surgical resection of the adrenal mass confirmed the pathologic diagnosis and provided definitive cure.
