To determine the prognostic significance of the immunophenotype, density and distribution of tumor-infiltrating lymphocytes (TILs) in breast cancer samples....

In this study, 50 cases of angioimmunoblastic T-cell lymphoma (AITL) were investigated for histological patterns, their association with Epstein-Barr virus (EBV) infection, B cell and T cell clonalities, and the clini- cal outcomes. Three histological patterns were identified: the classical pattern (34 cases), large-cell rich pat- tern (14 cases)...

To assess the pathologic outcome of BI-RADS mammographic classification and the success of stereotactic biopsy for such lesions. Materials and...

Chondrosarcoma of distal phalanx is extremely rare and to our best knowledge there was only one case having magnetic resonance ( MR ) imaging study. We report a case of 56-year-old woman developing chondrosarcoma of distal phalanx of the left ring finger. The radiographic and imaging studies highly suggested chondrosarcoma and amputation of distal...

Diffuse large B-cell lymphoma (DLBCL) can be found involving bone marrow in approximately 11-27% of cases 1. Patterns of involvement are variable; these include diffuse pattern (lymphomatous cells diffusely infiltrating the marrow), interstitial pattern (i.e. small amount of lymphomatous cells scattered among hematopoietic cells), nodular pattern (lymphomatous cells forming aggregates in intertrabecular or paratrabecular area of the marrow).. ...

Primary sinonasal mucosal melanoma is a rare neoplasm. Like in other sites of malignant melanoma, the histopathology is variable and when lacking of melanin pigment, particularly in small biopsy specimen mimicks many neoplasms. Immunohistochemical staining plays an important role. Many immunomarkers, including S-100, HMB-45 and Melan-A should be...

We aimed to evaluate the role of frozen section (FS) and preoperative fine-needle aspiration cytology (FNA) in thyroid nodular lesions. ...

Sclerosing polycystic adenosis (SPA) is a rare tumor-like lesion of the salivary gland that bears a histomorphological resemblance to fibrocystic disease and sclerosing adenosis of the breast. The lesion is widely considered to be a pseudoneoplastic inflammatory process. However, foci of epithelial dysplasia and carcinoma in situ can occur in the...

Fine needle aspiration (FNA) cytology of suspected salivary gland lesions has an established role in preoperative diagnosis and management of patients. However diverse morphological patterns and overlapping features make it a challenging job, to give a precise diagnosis, at times. The aim of the present study is to investigate the accuracy...

Tuberculosis is a treatable disease, but remains a major cause of mortality. Culture for Mycobacterium is needed to make a definitive diagnosis; thus, loop-mediated isothermal amplification (LAMP) was attempted for its detection in formalin-fixed, paraffin-embedded (FFPE) samples. Materials and method: Archival FFPE blocks were used from 64 patients...
