Adrenal ganglioneuroblastoma is an extremely rare tumor among adrenal neoplasms in adult. We reported a 26-year-old young female patient presented with vague pain in left plank. Abdominal sonography and CTScan revealed a heterogenous solid lobulated left adrenal mass which contenting central necrosis, hemorrhage, coarse calcification and multiple adjacent metastasized lymphoid nodules, hence adrenal cortical carcinoma was not excluded although testing for adrenal function were normal.

Whether patients with non-small cell lung cancer (NSCLC) with unexpected pleural dissemination (UPD) could get survival benefit from tumor resection remained controversial. Main tumor and visible pleural nodule resection could improve prognosis in patients with UPD who could not receive adjuvant targeted therapy.

Bronchiolar adenoma(BA) is a recently recognized, rare tumor of the bronchioles. It can be divided into proximal and distal types according to the proportion of mucinous and ciliated cells on the luminal surface. BA is often misdiagnosed because it has similar ultrasonographic, gross and histological presentations as other diseases.

Angiogenesis is a proliferative process resulting in the development of new blood vessels from existing endothelial cells and is considered crucial for tumor growth and metastasis. Tumor angiogenesis can be quantified by microvascular density (MVD), which is evaluated in highly vascularized tumor areas (hot spots) by immunohistochemical assays using CD34 and CD31 pan-endothelial antibodies.

Patients with single hepatocellular carcinoma (HCC) usually undergo transarterial chemoembolization (TACE) if they are not candidates for curative surgical or ablative therapy. The primary aim of the study was to assess the overall survival and clinical determinants of survival in patients with single HCC who underwent TACE.

Analysis of molecular markers in addition to cytological analysis of fine-needle aspiration (FNA) samples is a promising way to improve the preoperative diagnosis of thyroid nodules. Nonetheless, in clinical practice, applications of existing diagnostic solutions based on the detection of somatic mutations or analysis of gene expression are limited by their high cost and difficulties with clinical interpretation.

Thyroid cancer is the second most common cancer diagnosed during pregnancy after breast cancer. The goal of management is to control malignancy and prevent maternal and fetal complications as a result of maternal hypothyroidism. The role of female sex hormones as an etiologic factor was investigated, with no clear association. Pregnancy can cause an increase in size of a previously existed thyroid nodule through the structural similarity between TSH and BHCG, and the normally expressed estrogen receptors on thyroid gland cells.

Subjects and methods: 72 patients with thyroid nodules were performed clinical examination, 2D ultrasound, Doppler and strain elastography for qualitative assessment of the stiffness of thyroid tumors according to Asteria scores (2008) from ES1 - ES4, semi-quantitative calculating elasticity of the tumors (E2) and normal parenchyma (E1), strain ratio: SR = E2/E1, comparing with fine needle aspiration results.

Rarely, corticotropin-releasing hormone (CRH) is produced by pancreatic islet tumors, SCLC, medullary thyroid cancer, carcinoids, or prostate cancer. When levels are high enough, CRH can cause pituitary corticotrope hyperplasia and Cushing's syndrome. Tumors that produce CRH sometimes also produce ACTH, raising the possibility of a paracrine mechanism for ACTH production. A distinct mechanism for ACTH-independent Cushing's syndrome involves ectopic expression of various G protein–coupled receptors in the adrenal nodules.
