We selected 63 prostate tumors with Gleason's grade 6 (3+3), commonly showing both tubular and cribrous patterns. We compared in both patterns the expression of two of the most used biologic markers: PCNA and p53, with the aim to verify the validity of the Gleason's grading system to compare the morphologic grade with biologic aggressiveness and prognostic(More)
We present a case of late granulomatous reactions from silicone that first appeared in a site different from that of the injection causing an incorrect diagnosis of liposarcoma in the beginning. The histological picture was a cystic-macrophagic granuloma in both the injection site (upper lip) and the migrating site (paranasal regions). We think that the(More)
We describe a rare case of a solid variant of a mammary adenoid cystic carcinoma with basaloid features (sbACC) and its coexistence with a "small cell" carcinoma (SCC), identified and confirmed by histological and immunohistochemical observations: the absence of glandular structures and PAS-positive globules, positivity for neuroendocrine markers (NSE,(More)
Breast cancer is a heterogeneous disease, so therapeutic predictive biological markers need to be identified. To date an accurate evaluation of predictive markers is mainly done at the primary site; however, the main goal of adjuvant therapy for breast cancer is the control of micrometastases. The aim of this study is to assess as therapeutic and/or(More)
A case of monostotic fibrous dysplasia in a 54-year-old male complaining of severe pain in the right hip is presented. Imaging findings demonstrated an extremely aggressive lesion involving bones, liver, lungs, and lymph nodes, and suggested the possibility of sarcomatous transformation. Histological examination established a diagnosis of metastatic(More)
The Authors have examined 1159 lymph nodes obtained from 64 cases of breast carcinoma to value the presence of a correlation between the insurgence of metastases and lymph node dimensions. Metastases were more frequent in larger lymph nodes. Nevertheless, metastases were also present in small (< 5 mm) or very small (< 2 mm) lymph nodes. This indicates the(More)
Thymidylate Synthase (TS) is the key enzyme for DNA synthesis pathways and is inhibited by 5-fluorouracil (5FU). The aim of this work was to study TS expression and the proliferation rate in the different histological types of colorectal carcinoma (CRC). 50 patients with CRC were included in this study and evaluated immunohistochemically using the(More)
We evaluated variations in serum levels of N-terminal peptide of type III procollagen (PIIIP) and laminin (Lam-P1) in 36 anti-HCV positive patients, confirmed by RIBA II, with chronic hepatitis treated with alpha interferon (IFN) at a dose of 6 million units (MU) three times for week for 6 months, followed by 3 MU three times for week for a further 6(More)
Pleomorphic Hyalinizing Angiectatic Tumor (PHAT) is a rare benign lesion characterized by slow growth, infiltrative behavior and high rate of local recurrences. Only one case has been described in retroperitoneum, at renal hilum, but not involving pelvis or parenchyma. Here we present the first case of PHAT arising in the renal parenchyma. A nodular lesion(More)
