Papillary carcinoma of the male breast: report of a case.

Intracystic papillary carcinoma of the male breast represents an extremely rare entity that accounts for less than 1% of all malignancies, and histologically may range from papillary hyperplasia in gynecomastia to invasive papillary carcinoma. This report presents the case of a 61-year-old Caucasian man who presented with a 5-year history of a centrally located painless swelling of his right breast with occasional nipple discharge. Triple assessment was very helpful in establishing the diagnosis.

Fine needle aspiration cytology in primary breast angiosarcoma: a case report.

Background: Angiosarcoma of the breast is an uncommon, aggressive, vascular tumor. The cytomorphologic features of angiosarcomas have rarely been reported.

Case: The present study describes a case of breast angiosarcoma initially diagnosed by fine needle aspiration cytology.

Primary osteogenic sarcoma of the breast: cytomorphologic study of 3 cases with histologic correlation.

Background: Primary osteogenic sarcomas of the breast are extremely rare neoplasms. The histologic and cytologic features are comparable to those of their soft tissue and skeletal counterparts. To assess the utility of fine needle aspiration (FNA) in preoperative identification of osteogenic sarcomas, we retrospectively reviewed the FNA findings of 3 cases diagnosed in our hospital over 2 1/2 years.

Prognostic impact of Deoxyribonucleic acid (DNA) image analysis cytometry and immunohistochemical expression of Ki67 in surgically resected non-small cell lung cancers.

Background: The aim of the present study was to evaluate the prognostic significance of DNA ploidy and Ki67 expression in non-small cell lung carcinoma (NSCLC).

Methods: This prospective study included 96 patients with stages I-IIIA NSCLC who underwent surgical excision. DNA image analysis cytometry was applied on imprints.

Cytogenetic profile of unknown primary tumors: clues for their pathogenesis and clinical management.

Unknown primary tumors (UPTs) represent an entity of great clinical and biological interest, whose origin cannot be determined even after medical workup. To better understand their pathogenesis by outlining their genetic composition, 20 UPTs were investigated by G-banding, supplemented with Fluorescence In Situ Hybridization and Comparative Genomic Hybridization analyses. The data obtained were sufficient to reach a diagnosis in five cases-four lymphomas and one Ewing sarcoma-demonstrating that in a subset of UPTs, cytogenetics can be an adjunct for differential diagnosis.
