OBJECTIVE We report a case of an adrenal collision tumor composed of a small cell lung carcinoma metastasis and a benign adrenal adenoma identified preoperatively on FDG-PET, CT and MRI and confirmed pathologically. METHODS The patient's history, preoperative imaging characteristics, postoperative course, and histopathology are described. A review of the literature addressing adrenal collisio...

Malignant peripheral nerve sheath tumors (MPNSTs) have rarely been reported to occur in the adrenal gland and all of the reported cases were associated with neurofibromatosis, pheochromocytoma or ganglioneuroma. We present here a case of MPNST in the bilateral adrenal glands without any history of neurofibromatosis or combined tumor. Histologic examination showed the tumor cells had a spindle t...

BACKGROUND The endocrine adrenal gland has 3 zones comprised of the cortex and medulla. The character of multi-hormonal expression results in multiple clinical manifestations. To define the clinical characteristics of adrenal tumors in Taiwan, we reviewed 336 pathologically proven adrenal tumors at Chang Gung Memorial Hospital in Linkou. METHODS We retrospectively analyzed 258 pathologically ...

INTRODUCTION Pancreatic neuroendocrine tumors are rare. Treatment includes aggressive local management of the primary lesion and metastases, and systemic somatostatin. This is the first report of an isolated metachronous metastasis to the adrenal gland from a pancreatic neuroendocrine tumor that presented 90 months after the primary tumor. PRESENTATION OF CASE The patient presented as a 53yo ...

Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy. Sarcomatoid adrenal carcinoma is even more aggressive type of ACC. Bilateral malignant adrenal tumors are extremely rare except for those that represent metastasis from an extra-adrenal organ. Here we report a 53-year-old woman who presented with abdominal pain and weight loss. Abdominal computed tomography revealed bilateral a...

A pheochromocytoma was maintained in rats from the New England Deaconess Hospital by giving the rats s.c. injections of isolated tumor cells. The animals were sac rificed 3 to 4 weeks after transplantation, the tumors were excised, and purified tumor cells were prepared. Cyclic nucleotide phosphodiesterase of the purified tumor cells was characterized and compared with that of the adrenal medul...

We report a rare case of virilizing adrenal cancer with tumorous invasion of the left renal vein in which a retroperitoneal adrenalectomy with bail-out nephrectomy was performed. A tumor thrombus infiltrated the wall of the left adrenal vein and extended into the left renal vein. Initially, a kidney sparing procedure with partial tangential excision of the involved renal vein wall was performed...

A three-month-old female infant presented with abdominal distention for 2 months. A large palpable mass in right upper quadrant was noted on physical exam. Abdominal ultrasound revealed a large heterogeneous mass with multiple cystic components. Mass was surgically excised and pathology was consistent with mature adrenal teratoma. Teratoma is a germ cell tumor mainly found in gonadal tissues. O...

Schwannomas usually occur in adults being between the second and fifth decades, and such neoplasms are extremely rare in a pediatric population. In addition, they are not normally found in the retroperitoneal region. Here, we present a pediatric case of a retroperitoneal schwannoma in an adrenal location where the tumor was not able to be preoperatively differentiated from other benign or malig...

Testicular adrenal rest tumors (TART) occur often as asymptomatic nodules in corticotropin-dependent lesions aberrant adrenal tissue in congenital adrenal hyperplasia (CAH) patients. The present manuscript is about an unusual case of a 16-year-old CAH patient due to 11β-hydroxylase deficiency. He underwent testicle biopsy because of testicle tumor suspicion and diagnosed with TART.
