ContextPrimary adrenal angiosarcoma is an extremely rare neoplasm, as are combined tumors within a given adrenal lesion.Clinical presentation and interventionA 35-year-old man presented with hypokalemic hypertension leading to the discovery of a 6 cm diameter malignant-appearing right adrenal tumor. The lesion displayed marked 18F-fluorodeoxyglucose uptake on positron emission tomography scanning. Endocrine investigations revealed secretion of both cortisol and aldosterone by the neoplasm. The entire right adrenal gland along with the periadrenal fat tissue was removed during laparoscopic surgery.ResultsHistological examination revealed two intermingled tumor cell proliferations, namely an angiosarcoma and an adrenocortical adenoma. An extensive post-operative search revealed no other primary tumor site, nor metastases. The lesion was then considered to be a primary adrenal angiosarcoma combined with a secreting adrenocortical adenoma. The patient received four cycles of chemotherapy (adriamycin/ifosfamide). At 2-year follow-up, he is alive and well, with no sign of relapse.ConclusionTo the best of our knowledge, this is the first case of an adrenal neoplasm combining a primary angiosarcoma and a functioning adrenocortical adenoma.

Combined 17alpha-hydroxylase/17,20-lyase deficiency is a rare, autosomal recessive form of congenital adrenal hyperplasia characterized by the coexistence of hypertension, caused by the hyperproduction of mineralocorticoid precursors and DSD in males and sexual infantilism in females, due to impaired production of sex hormones. Several CYP17 mutations resulting in 17alpha-hydroxylase/17,20-lyase deficiency have been reported previously. In the present study, we described a novel CYP17 mutation in two Brazilian sisters with primary amenorrhea, 46,XY karyotype, high basal levels of progesterone (3.4-4.9 ng/mL) and hypokalemic hypertension born to consanguineous parents. After PCR and automatic sequencing of CYP17 coding region, 25 bp duplication at exon 5 was found in the patients. This duplication started at codon 318 resulting in a premature stop codon at position 320 resulting in an ineffective and truncated protein and in accordance with the molecular modeling of P450c17. Therefore we expanded the repertoire of CYP17 mutations describing the largest duplication found in this gene in both sisters, with a clinical phenotype of combined 17alpha-hydroxylase/17,20-lyase deficiency and emphasizes the importance of the P450c 17 molecular modeling to predict the functional effect of these mutations.
