Bronchiolo-alveolar carcinoma with subcutaneous chest wall metastasis is a very rare presentation. A case of 36- year-old male with metastatic subcutaneous chest nodule of bronchiolo-alveolar carcinoma, diagnosed by fine needle aspiration cytology, is reported here. Cutaneous metastases are of diagnostic importance because they may be the first manifestation of an undiscovered internal malig...
Reasons for early onset skin cancer are poorly understood. Microarray analysis revealed overexpression of the Scca2 gene in the 12-O-tetradecanoylphorbol-13-acetate-treated skin of Car-S mice, or line phenotypically selected for high susceptibility to two-stage skin carcinogenesis, as compared with 12-O-tetradecanoylphorbol-13-acetate-treated skin of Car-R mice, which is resistant. A human skin...
We show that diverse human tumors obtained directly from surgery or biopsy can grow at high frequency in vitro for long periods of time and still maintain many of their in vivo properties. The in vivo properties maintained in vitro include three-dimensional growth; maintenance of tissue organization and structure, including changes associated with oncogenic transformation; retention of differen...
The molecular scenario of breast cancer has become more complex in the last few years. Distinguishing between BRCA-associated, sporadic, HER2-enriched and triple-negative tumors is not sufficient to allow effective clinical management. Basal-like breast cancer, a subtype of triple-negative breast cancer, differs from others grouped under this heading. Commonalities between BRCA-related tumors a...
PURPOSE To report two cases of retinitis pigmentosa (RP) associated with vasoproliferative tumors (VPTs) and Coats-like fundus. CASE REPORTS Two patients with RP presented with recent loss of vision due to combined VPTs and Coats-like retinal vascular alterations. One patient had two VPTs with adjacent capillary nonperfusion, telangiectasia and aneurysmal vascular changes in one eye. The othe...
Proopiomelanocortin is a polypeptide precursor molecule, the processing of which generates ACTH, beta-endorphin, the beta- and gamma-lipotropins, the joining peptide, and the NH2-terminal fragment. Anterior pituitary corticotrophs are the major site of proopiomelanocortin gene expression in man and the predominant, if not sole source of circulating ACTH. Recent data have established that proopi...
