Aberrant adrenocortical tissue in hernia sac occurring in an adult: case report and review of the literature

Adrenal Rests in the Uro-genital Tract of an Adult Population

Ectopic adrenal rests are a rare condition which can be found in various sites, generally in the retroperitoneum or pelvis along the path of gonadal descent. Their real prevalence is unknown. Males are more commonly affected, at least in the pediatric age. Adrenal rests are usually clinically silent and incidentally found in surgical samples, mostly in the pediatric population, and rarely in adults. With the aim of increasing knowledge and estimating the prevalence of ectopic adrenocortical tissue in the adult population, 44 adrenal rests in the urogenital tract of 40 adults are described. These represent approximately 0.07% of the total number of urogenital and gynecological surgeries performed in the 22 considered years. Adrenal rests were identified in the spermatic cord (10 males) and in paraovarian, parasalpingeal, or infundibulopelvic ligament locations (30 females). All but one was incidental findings. One case regarded an adrenocortical carcinoma arisen in adrenal rests. A literature review of adrenal ectopia in the urogenital tract of adults identified 57 reported cases from 53 patients, with similar clinicopathological features as those of our series, with the exception of a lower incidence of parasalpingeal locations. Despite their limited clinical implications, awareness of ectopic adrenal rests is essential also in adults for at least two reasons: (a) to correctly identify sources of adrenocortical hormone production in case of adrenal insufficiency or hormonal imbalance and (b) to avoid misinterpretations in the diagnostic workup of renal cell carcinoma, adrenocortical tumors, and rare gonadal neoplasms, including Sertoli/Leydig cell tumors.

Adrenal ectopy and lipoma of an inguinal hernia sac: A case report & literature review

•

Ectopic adrenocortical tissue is accessory adrenal cortex tissue outside of the adrenal glands.

•

Ectopic adrenocortical tissue is a rare finding during inguinal hernia repair in adults.

•

Adrenocortical tissue in inguinal hernia sacs can mimic metastatic deposits.

•

Surgical excision of adrenocortical tissue may have endocrine implications.

•

We have described a case of adrenocortical tissue identified in a lipoma of an inguinal hernia sac.

Introduction & importance

Ectopic adrenocortical tissue is the presence of accessory adrenal cortex tissue located outside of the adrenal glands. It is a rare, incidental finding during inguinal hernia repair. This case report aims to discuss the anatomy and important patient implications related to this finding.

Case presentation

A 61-year-old male presented with a long-standing right direct inguinal hernia increasing in size and pain frequency. During open right anterior inguinal hernia repair, a lipoma was identified inside the hernia sac and removed. Further histopathological examination of the specimen revealed the presence of adrenocortical tissue inside the lipoma. No further interventions were performed. The postoperative and 2-year follow-up course were uneventful.

Clinical discussion

Adrenocortical tissue can parallel the descent of the gonads during embryogenesis, arresting at any point along this path, including the inguinal region. Ectopic adrenocortical tissue is commonly found during inguinoscrotal procedures in infants, suggesting early involution. Its incidence in hernia sacs should be recognized to prevent misdiagnosis as neuroendocrine tumors or melanomas. If adrenocortical tissue is identified during hernia reduction, further surgical exploration is not recommended. In terms of prognosis, endocrine imbalances following surgical removal cannot be ruled out, promoting careful patient monitoring. The lipoma containing the adrenal tissue in our case is a common finding during hernia repair, identified in 22% of patients at operation.

Conclusion

Ectopic adrenocortical tissue is a rare, incidental finding during inguinal hernia sac analysis in adults. This finding should be well-documented following removal and further studies are required to evaluate long-term outcomes.

Ectopic adrenal gland in an adult inguinal hernial sac: A case report

•

Ectopic adrenocortical tissue is a rare finding that can be encountered in inguinal hernial sacs of adults.

•

Surgeons should be aware of this and are encouraged to resect Ectopic adrenocortical tissue when grossly identified.

•

Secondary hyperplasia after adrenalectomy, adrenal insufficiency, and neoplastic transformation should all be considered.

Introduction

A 37-year-old male patient operated for inguinal hernia repair was found to have ectopic adrenocortical tissue in the hernial sac.

Case presentation

A 37-year-old man was admitted for bilateral inguinal hernia. An uneventful open repair was done, and the resected hernial sacs were sent to pathology. Histopathology reported the presence of adrenocortical tissue in the right inguinal hernial sac.

Discussion

Ectopic adrenocortical tissue (EACT) in the groin region is not an unusual finding in children, however, it’s rarely reported in adult patients. Only 9 cases have been reported in English describing EACT in an adult’s inguinal hernia. The finding can be attributed to the close proximity of the developing gonads and adrenal cortex during embryogenesis, and subsequent mechanical translocation of adrenocortical tissue during testicular descent. Some theoretical clinical implications exist for this condition, including secondary hyperplasia after adrenalectomy, adrenal insufficiency in certain situations, and possible neoplastic transformation. Generally, it is recommended that surgeons resect ectopic adrenal glands when identified intra-operatively. However, actively searching for these glands has no known benefit and carries some surgical risks, and is hence not recommended. It is reasonable as well, that clinicians keep the clinical implications of this finding in mind during future follow-ups with such patients.

Conclusion

The presence of ectopic adrenocortical tissue in inguinal hernia sacs is a rare encounter in adults. The condition can have several theoretical clinical implications that need to be considered by surgeons while assessing patients in whom this phenomenon is observed.

Swyer Syndrome with Heterotopic Adrenal Cortical Tissue in Streak Gonads: A Rare Case and Review of Literature

Swyer syndrome is a 46 XY pure gonadal dysgenesis. Affected individuals are phenotypically female with external female genitalia, hypoplastic Mullerian structures, and the presence of streak gonads. Gonadectomy is indicated due to increased risk of development of malignancy in streak gonads. We hereby report a case of 15-year-old patient with Swyer syndrome who underwent laparoscopic gonadectomy. Histopathological examination showed streak gonads with the presence of accessory adrenal cortical tissue. The patient was put on hormonal replacement therapy postsurgery. Heterotopic adrenal rest may be an incidental finding in normal ovary and testis. Its presence in streak gonads has never been reported, and we propose a theory of increased risk of gonadal and adrenal tumors, possibly because of mutations in disorders of sex differentiation.

Adrenal ectopy of adult groin region: a systematic review of an unexpected anatomopathologic diagnosis

PURPOSE

Adrenal ectopy is a rare condition, caused by abnormal embryological development of the adrenal glands and testis. This anomaly is asymptomatic and is generally diagnosed in childhood. Most cases of adrenal ectopy of the groin region have been found incidentally during surgery. This review aims to evaluate the incidence of adrenal ectopy of the adult groin region, as well as its short- and long-term significance.

METHODS

A systematic literature search was performed using the EMBASE, MEDLINE, PubMed and Cochrane Central databases to identify all studies published until December 2015. Articles written in English containing the keywords: ''ectopic adrenal tissue'' or ''aberrant adrenal tissue'' or ''adrenal heterotopy'' combined with ''groin region'' or ''inguinal'' or ''testicular" or "scrotum" and "adult" were selected.

RESULTS

Fifteen articles matched the review criteria. A total of 21 cases (100 % male) were included. No cases of bilateral nodules have been reported. The mean age at diagnosis was 43.5 years old (range 19-78 years). A predominance of right-sided lesions was observed (71.4 %). The mean size reached 7.6 mm (range 2-40 mm) and hernia sacs were the most common location (47.6 %). All histological analyses of harvested tissues consisted of adrenal cortex without medulla.

CONCLUSIONS

Our results suggest that routine pathological examination of any groin tissue excised during inguinal hernia repairs is required for the diagnosis of adrenal ectopy in the groin. Although there is no current evidence that endocrine or oncologic complications can occur from excision of ectopic adrenal tissue, further confirmatory studies may be required.

Adrenal rests associated with ectopic testis in an adult: Clinical significance

Ectopic adrenal tissue may be present along the path of the testis and discovered during groin surgery. The condition has been mainly reported in the pediatric population and very rarely in adults. Here, we report on the case of an adult male with undescended testis who received orchidectomy, and ectopic adrenal tissue was discovered in the removed specimen. The clinical significance of such a condition is discussed.
