The medical community in Brazil has brought to light a significant clinical oversight that underscores the critical intersection of urological oncology and endocrinology. Researchers recently published a detailed case study in JCEM Case Reports, highlighting the journey of a 22-year-old male who suffered an acute adrenal crisis following a bilateral radical orchiectomy. The surgical procedure, intended to treat what were misinterpreted as malignant testicular tumors, instead revealed a lifelong, untreated case of Congenital Adrenal Hyperplasia (CAH). This case serves as a poignant reminder of the complexities surrounding Testicular Adrenal Rest Tumors (TARTs) and the importance of multidisciplinary diagnostic protocols.
The Clinical Presentation and Initial Surgical Intervention
The patient’s journey toward a diagnosis began approximately three years prior to his surgery when he first noticed the development of masses in both testes. Despite the progressive growth of these masses, he did not seek immediate medical intervention until the discomfort and size became unavoidable. Upon presentation to a urological surgical team, a physical examination confirmed the presence of large, bilateral testicular masses.
In the field of urology, bilateral testicular tumors are relatively rare, often raising suspicion of systemic issues or synchronous germ cell tumors. However, in this instance, the surgical team proceeded with the suspicion of malignancy. To preserve the possibility of future biological children, the patient underwent sperm cryopreservation before the procedure. Subsequently, a bilateral radical orchiectomy—the complete removal of both testes—was performed.
The immediate perioperative period appeared successful. The surgeons reported no immediate complications, and the patient was discharged the following day. At this stage, the medical team believed they had successfully removed a potentially life-threatening malignancy. However, the subsequent weeks would reveal that the surgery had inadvertently stripped the patient’s body of a critical hormonal buffer, triggering a cascading physiological failure.
Post-Surgical Complications and the Emergence of Adrenal Crisis
Eighteen days after his discharge, the patient returned to the hospital in a state of severe physical distress. He presented with profound asthenia (weakness), persistent nausea, vomiting, and clinical signs of dehydration. These symptoms are hallmark indicators of an adrenal crisis, a life-threatening medical emergency where the body lacks sufficient cortisol to maintain basic metabolic and cardiovascular functions.
Upon readmission, an endocrinology specialist was consulted. The specialist’s physical examination immediately identified several "red flag" symptoms that had seemingly been overlooked during the initial urological evaluation. These included a noticeably short stature and hyperpigmented macules on the lips. In patients with untreated CAH, the body overproduces Adrenocorticotropic Hormone (ACTH) in a futile attempt to stimulate the adrenal glands. This excess ACTH can cross-react with melanocortin receptors, leading to the characteristic hyperpigmentation seen in this patient.
The patient was stabilized with glucocorticoid replacement therapy, transitioning to oral prednisolone. While he was initially discharged after stabilization, his recovery was short-lived. Eight days later, he was readmitted with symptomatic hyponatremia—a dangerously low level of sodium in the blood. This electrolyte imbalance is a direct consequence of mineralocorticoid deficiency, common in the salt-wasting forms of CAH, where the body cannot retain sodium or excrete potassium effectively.
A Chronology of Missed Opportunities and Medical History
A retrospective review of the patient’s medical records revealed a tragic history of missed diagnostic opportunities and lost follow-ups. The patient had not undergone neonatal screening for CAH at birth, a practice that is now standard in many parts of the world but was less consistent two decades ago.
At age three, the patient had been evaluated by a pediatric endocrinologist for macrogenitosomia (unusually large external genitalia for his age). At that time, a diagnosis was suspected, but medical history indicates a combination of misdiagnosis and a severe intolerance to the prescribed medication. These factors led the family to cease treatment, and the patient was lost to follow-up for nearly 20 years.
During those two decades, the patient survived without medical intervention. He reported no classic "salt-craving" behavior or previous hospitalizations that would suggest an earlier adrenal crisis. This suggests his body had reached a precarious equilibrium, likely aided by the hormonal output of the TARTs themselves, which can sometimes produce enough steroid intermediates to stave off a full-blown crisis until a major physiological stressor—like surgery—occurs.
The family history provided further context. The patient’s brother also exhibited short stature and precocious puberty, symptoms characteristic of CAH. His diagnosis was only confirmed recently, following the patient’s crisis. Notably, the brother’s scrotal ultrasonography did not reveal TARTs, illustrating the variable expression of the condition even within the same family. Furthermore, a sister had died at just two months of age from an undetermined cause, a tragedy that the authors suggest may have been an undiagnosed neonatal salt-wasting crisis.
Diagnostic Confirmation: Imaging and Genetic Testing
Following the post-surgical crisis, a series of comprehensive tests were conducted to confirm the underlying pathology. A CT scan revealed diffuse bilateral adrenal hyperplasia. Interestingly, this significant enlargement of the adrenal glands had not been identified or reported in the preoperative imaging conducted by the urological team, highlighting a potential gap in the initial radiological review.
Laboratory testing performed 25 days after the surgery showed massive elevations in serum 17-hydroxyprogesterone (17-OHP) and androstenedione. These are the classic biochemical markers of 21-hydroxylase deficiency, the most common form of CAH. In this condition, an enzyme deficiency blocks the pathway to cortisol and aldosterone, leading to a "backlog" of precursors that are instead shunted into androgen production.
Definitive confirmation came through genetic testing. Researchers identified a homozygous c.293-13 C > G [I2G] pathogenic variant in the CYP21A2 gene. This specific mutation is associated with a severe reduction in enzyme activity, typically resulting in the salt-wasting or simple-virilizing forms of the disease.
Understanding TARTs: The Pathophysiological Link
Testicular Adrenal Rest Tumors (TARTs) are a well-recognized but frequently misunderstood complication of CAH. During embryonic development, adrenal and gonadal tissues originate from nearby locations. Occasionally, vestigial adrenal cells migrate along with the descending testes. In healthy individuals, these cells remain dormant.
However, in patients with CAH, the lack of cortisol leads to a chronic elevation of ACTH. This hormone acts as a growth factor for these vestigial adrenal cells, causing them to proliferate and form tumors within the testes. Because these tumors are composed of adrenal-like tissue, they are benign but can cause significant damage. They often grow near the mediastinum testis, where they can compress the seminiferous tubules, leading to obstructive azoospermia and permanent infertility.
The authors of the paper emphasize that while TARTs are often linked to inadequate glucocorticoid treatment, they can also occur in patients who appear to have adequate hormonal control. This necessitates regular ultrasound screening for all male patients with CAH, starting in late childhood or early adolescence.
Analysis of Implications for Clinical Practice
The case of this 22-year-old man highlights several critical failures in the standard diagnostic pipeline. The first is the failure of differential diagnosis. When presented with bilateral testicular masses, the possibility of TARTs should always be considered, especially if the patient exhibits other signs such as short stature or hyperpigmentation.
The decision to perform a radical orchiectomy without an endocrinological consultation resulted in the irreversible loss of the patient’s testes. Had the tumors been correctly identified as TARTs, the appropriate treatment would have been aggressive glucocorticoid therapy to suppress ACTH levels, which often leads to a reduction in tumor size and can sometimes restore fertility. Surgery is typically reserved only for cases that do not respond to medical management or cause extreme pain.
From a journalistic perspective, this case also sheds light on the broader issue of healthcare continuity. The "loss to follow-up" for 20 years represents a systemic failure in transitioning pediatric patients with chronic conditions to adult care. It also highlights the importance of universal newborn screening, which can prevent such lifelong mismanagements by identifying the condition before symptoms even appear.
Official Recommendations and Conclusion
The researchers conclude their paper with a clear call to action for the medical community. They state that in any case of bilateral testicular tumors, TART must be included in the differential diagnosis. Such a finding should immediately raise clinical suspicion of previously undiagnosed or untreated CAH.
"TARTs can also occur in patients with adequate hormonal control, underscoring the need for regular screening in all male patients with CAH," the authors write. They advocate for a multidisciplinary approach involving urologists, endocrinologists, and radiologists to ensure that patients receive accurate diagnoses and avoid unnecessary, life-altering surgeries.
This case serves as a somber lesson in the necessity of looking beyond the immediate surgical site. For the 22-year-old patient in Brazil, the price of a missed diagnosis was the loss of his testes and a brush with a fatal adrenal crisis. For the global medical community, his story is an essential data point in the ongoing effort to refine the management of congenital adrenal hyperplasia and its complex manifestations. The integration of genetic testing, better radiological awareness, and rigorous adherence to screening protocols remains the best defense against such preventable clinical tragedies.
