46, XY agonadism associated with adrenal adenoma/myelolipoma: report of a case analyzing Y-chromosome-specific sequences

Perspectives in Pediatric Pathology, Chapter 5. Gonadal Dysgenesis

One of the most challenging areas in pediatric testicular pathology is the appropriate understanding and pathological diagnosis of disorders of sexual development (DSD), and in particular, the issue of gonadal dysgenesis. Here we present the main concepts necessary for their understanding and appropriate classification, with extensive genetic correlations.

A unique case of synchronous functional adrenocortical adenoma and myelolipoma within the ectopic adrenal cortex in a child with Beckwith-Wiedemann syndrome

We report a unique case of synchronous functional adrenocortical adenoma and an incidental myelolipoma within ectopic cortical adrenal tissue located in the renal hilum in a child with Beckwith-Wiedemann syndrome and review the association between adrenal gland disorders and myelolipomas. To the best of our knowledge, this is the first documented case of a simultaneous occurrence of these three conditions. A 17-month-old child with Beckwith-Wiedemann syndrome was diagnosed with a left adrenal tumor during complementary radiologic studies. Biochemical investigation before surgery showed elevated blood levels of cortisol and dehydroepiandrosterone hormones. The patient underwent a left adrenalectomy with ipsilateral renal hilar and intercaval-aortic lymph node dissection. Pathology findings revealed a left adrenocortical adenoma and an incidental myelolipoma growing within ectopic cortical adrenal tissue in the renal hilum. The patient is doing well and does not have any current health issues. Patients with adrenal cortex disorders, such as hyperplasias and neoplasms, particularly when associated with hormonal imbalances, may have an increased risk of developing myelolipomas. Whether Beckwith-Wiedemann syndrome may, by itself, contribute to simultaneous occurrence of adrenocortical adenomas and myelolipomas remains to be clarified.

Composite adenomatoid tumor and myelolipoma of adrenal gland: report of 2 cases

Adenomatoid tumor and myelolipoma are benign, hormonally inactive tumors that are often incidental findings in the adrenal glands. Myelolipoma is more common than adenomatoid tumor in this location but both are rare, and as yet, the pathogenesis of both remains unclear. We report 2 cases of composite adenomatoid tumor and myelolipoma, incidentally found in the adrenal gland on investigation for other diseases. To our knowledge, composite adenomatoid tumor and myelolipoma of adrenal gland has not been previously reported.
