Androgen secreting adrenocortical tumours.
BACKGROUND Androgen secreting adrenocortical tumours are rare in children and the determination of their malignant potential can be difficult. OBJECTIVES To assess the presentation, histology, and clinical behaviour of these tumours. SETTING Two tertiary referral centres. STUDY DESIGN Retrospective analysis of children diagnosed with an androgen secreting adrenocortical tumour between 197...
متن کاملAndrogen Secreting Ovarian Tumors
Other rare ovarian causes of hyperandrogenism include gynandroblastoma, gonadoblastoma, ovarian carcinoid, surface epithelial tumors (Brenner tumor) and metastatic tumors [5]. These tumors are rare representing only 10% of all ovarian tumors. Tumoral cause of hyperandrogenism is suspected when the serum testosterone levels are significantly elevated (>200 ng/ml), rapidly progressive symptoms of...
متن کاملGiant adrenal myelolipoma associated with 21-hydroxylase deficiency: unusual association mimicking an androgen-secreting adrenocortical carcinoma.
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 m...
متن کاملSex steroids in androgen-secreting adrenocortical tumors: clinical and hormonal features in comparison with non-tumoral causes of androgen excess.
OBJECTIVE Adrenocortical tumors (ACT) account for no more than 0.2% of the causes of androgen excess (AE). Conversely, these rare tumors have a very poor prognosis. It is difficult and important to exclude this diagnosis whenever there is AE. DESIGN Retrospective investigation of androgen profiles in a large consecutive series of androgen-secreting (AS) ACT to assess their relative diagnostic...
متن کاملSteroidogenic enzyme profile in an androgen-secreting adrenocortical oncocytoma associated with hirsustism
Hirsutism induced by hyperandrogenism can be associated with polycystic ovary syndrome, 21-hydroxylase (OH) deficiency or androgen-secreting tumors, including ovarian and adrenal tumors. Adrenal androgen-secreting tumors are frequently malignant. Adrenal oncocytomas represent rare causes of hyperandrogenism. The aim of the study was to investigate steroidogenic enzyme expression and steroid sec...
