Osteosarcoma metastatic to adrenal gland diagnosed by fine-needle aspiration

DIAGNOSTIC CYTOPATHOLOGY, Issue 3 2005
Noman H. Siddiqui M.D.
Abstract Osteosarcoma, a primary malignant tumor of the long bones, frequently metastasizes to the lungs. We report an unusual case of osteosarcoma metastatic to the right adrenal gland in a 37-yr-old male who presented 8 yr after remission with an adrenal mass. A preoperative diagnosis was made by fine-needle aspiration (FNA) biopsy. FNA biopsy revealed pleomorphic oval cells with prominent nucleoli, spindle cells, and giant tumor cells. Diagnostic osteoid was readily seen on smears and was also detected by polarization of cell-block section. Immunocytochemical stains revealed positivity of tumor cells for vimentin and osteonectin. Cytokeratin stains were negative. The cytologic diagnosis of metastatic Osteosarcoma was made, which was later confirmed upon resection of tumor by histology. Although the role of FNA in the diagnosis of primary bone tumors, including osteogenic sarcoma (OGS), remains controversial, this case, however, demonstrates the value of FNA biopsy combined with immunocytochemistry performed on the aspirated material in diagnosing osteosarcoma from an unusual location such as the adrenal gland.

Neurofibromatosis type 1: should we screen for other genetic syndromes?

EUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 9 2009
A case report of co-existence with multiple endocrine neoplasia 2A
Abstract Background, NF 1 is a genetic disorder with an autosomal dominant pattern of inheritence. It is associated with neoplastic disorders mainly derived from the neural seath. However, the co-existence of NF1 with the full spectrum of MEN 2A has rarely been reported. The aim of the study was to investigate the presence of secondary neoplasias in a patient with diagnosed NF1, and in particular the presence of hyperparathyroidism and the possible co-existence with another pheochromocytoma-related syndrome. Methods, We report a case of a 70 years old female patient who had NF1. The patient was referred to our center and was diagnosed with an isolated pheochromocytoma of the right adrenal gland for which she underwent right adrenalectomy. We further investigated for the presence of another pheochromocytoma-related syndrome and in particular for the presence of hyperparathyroidism and medullary thyroid cancer. Molecular screening for germline mutations of the genes NF1, RET and VHL has also been performed. Results, The patient was further diagnosed with hyperparathyroidism and medullary thyroid cancer, having the full spectrum of the clinical picture of the MEN2A syndrome. The genetic testing revealed the germline mutation for NF1 but not for the RET proto-oncogene which is generally found in MEN2A cases. Conclusion, To our knowledge this is a rare case of co-existence of two pheochromocytoma-related genetic syndromes, and generates the question of whether all patients with these syndromes should undergo a thorough clinical and laboratory investigation for the possibility of another co-existing pheochromocytoma-related genetic syndrome.

Transneuronal retrograde viral labeling in the brain stem and hypothalamus is more intense from the left than from the right adrenal gland,

MICROSCOPY RESEARCH AND TECHNIQUE, Issue 7 2008
Ida E. Tóth
Abstract Previous studies using the viral transneuronal tracing technique demonstrated central autonomic circuits involved in the innervation of the adrenal gland. Since increasing number of data indicate laterality in the neuroendocrine system, we aimed to investigate whether the supraspinal innervation of the adrenal gland exhibits asymmetry or not. The central circuitry involved in the innervation of the left and the right adrenal gland was studied in individual rats by dual transneuronal tracing using isogenic recombinant strains (Ba-DupGreen and Ba-Duplac expressing lacZ) of Bartha strain of pseudorabies virus. Viral infection of brain nuclei (dorsal vagal nucleus, nucleus of the solitary tract, caudal raphe nuclei, A5 cell group, hypothalamic paraventricular nucleus) from the left adrenal was more severe than that from the right organ. Dual-infected neurons were present both in the brain stem and in the hypothalamus. The results indicate a predominance in the supraspinal innervation of the left adrenal gland, and that each adrenal gland is innervated both by side-specific neurons and by neurons that project to both organs.

Adrenal rest tumor of the liver: A case report with immunohistochemical investigation of steroidogenesis

PATHOLOGY INTERNATIONAL, Issue 3 2000

Abstract A case of adrenal rest tumor arising in the liver of a 62-year-old male with chronic hepatitis type C is reported. The tumor was clinically non-functioning and required distinction from hepatocellular carcinoma. The yellowish,brown tumor measured 25 × 18 × 15 mm and was located in the subcapsular portion of the right hepatic lobe. Histologically, the tumor presented features similar to those of the adrenal cortex and was predominantly composed of pale cells. Electron micrograph revealed lipid droplets and mitochondria with tubulo,vesicular cristae, consistent with the characteristics of steroid-producing cells. Immunohistochemically, the tumor expressed the adrenal 4 binding protein and a number of enzymes involved in the synthesis of adrenocortical steroids. At surgery, the right adrenal gland was present independently from the liver. This hepatic tumor was considered to be an adrenal rest tumor with steroidogenic capability. [source]


A composite pheochromocytoma/ganglioneuroblastoma of the adrenal gland,

PEDIATRIC BLOOD & CANCER, Issue 7 2010
Elizabeth Lee Thiel MD
Abstract A 9-year-old female presented with a large abdominal mass. At surgery, the mass was noted to arise from the right adrenal gland. As the mass was manipulated, the patient developed severe hypertension. The final diagnosis was a cystic composite-pheochromocytoma/ganglioneuroblastoma. This compound adrenal tumor is only the fourth case reported in a child. Because composite pheochromocytomas are rare in the pediatric population, the management, optimal surveillance schedule and outcomes have not been characterized.

A different pattern of cytotoxic T lymphocyte recognition against primary and metastatic tumor cells in a patient with nonsmall cell lung carcinoma

Abstract BACKGROUND Lung carcinoma represents the most frequent cause of cancer death worldwide because of tumor metastases. The objective of the current study was to analyze the immunologic response during the progress of lung carcinoma metastasis. METHODS The authors established two tumor cell lines that were derived from primary and metastatic lesions in a patient with lung carcinoma (Patient G603). One cell line (G603L) was established from the primary lesion, and the other cell line (G603AD) was established from a metastatic lesion in the right adrenal gland 7 months after the patient underwent surgery for the primary lesion. Autologous regional lymph node lymphocytes were stimulated with CD80-transfected G603L cells, then cytotoxic T lymphocytes (CTLs) were induced against both lung carcinoma cell lines. RESULTS Both G603L cells and G603AD cells expressed Class I human leukocyte antigen, intracellular cell adhesion molecule 1, and lymphocyte-associated antigen type 3 (LFA-3), but not Fas or Fas ligand on their surfaces. By stimulation with CD80-transfected G603L cells, 2 CTL clones (H2/17 and H2/36) were established from the bulk CTLs. CTL clone H2/17 lysed G603L cells but not G603AD cells, suggesting that the antigen recognized by CTL clone H2/17 was abrogated during the process of metastasis. In contrast, CTL clone H2/36 lysed both G603L cells and G603AD cells, indicating that the antigen recognized by CTL clone H2/36 was maintained in the tumor cells throughout tumor progression. CONCLUSIONS The results demonstrated the possibility that some tumor-associated antigens may be abrogated during the process of metastasis, although others are maintained. The identification of these antigens will lead to a better understanding of their immunologic role during disease progression in patients with lung carcinoma.
