White adipose tissue (WAT) overgrowth in obesity is linked with increased aggressiveness of certain cancers. Adipose stromal cells (ASCs) can become mobilized from WAT, recruited by tumours and promote cancer progression. Mechanisms underlying ASC trafficking are unclear. Here we demonstrate that chemokines CXCL1 and CXCL8 chemoattract ASC by signalling through their receptors, CXCR1 and CXCR2,...

We describe 5 patients (mean age, 50 years; all had uterine bleeding) whose routine endometrial biopsy and curettage specimens contained prominent signet-ring cells. Each specimen contained loose aggregates of signet-ring cells scattered within the endometrial stroma that were characterized by peripherally displaced, small, uniform nuclei with indistinct nucleoli and showed no mitotic activity....

PURPOSE To report a case of atypical herpes simplex keratitis initially diagnosed as bacterial keratitis, in a contact lens wearer. RESULTS Case report of an 18-year-old woman using contact lenses who presented with pain, redness and gradual decrease in vision in the right eye. Examination revealed a paracentral large stromal infiltrate with a central 2-mm perforation. Corneal and conjunctiva...

We report the first case of inflammatory variant of hepatic angiomyolipoma (AML) with expression of transcription factor E3 (TFE3) protein but negativity for HMB45 and melan A in a 62-year-old female. Imaging studies revealed a tumor in the left lobe of liver, sized 5.8 cm in maximum diameter. Microscopically, the lesion was composed of large polygonal or epithelioid cells with copious eosinoph...

Inflammatory pseudotumors (IPT) form a group of etiologically, histologically, and biologically heterogeneous tumefactive lesions that are histologically characterized by prominent inflammatory infiltrates. IPT has been described in various organs including the lungs, bladder, liver, spleen, heart, and others. It may mimic a malignant tumor clinically and radiologically. We report a case of a 2...

The lymphoid stromal reaction, particularly the T lymphoid reaction, was studied immunohistochemically on cryostat sections in 14 cases of primary gastrointestinal B lymphomas, and compared with the type and distribution of lymphoid cells in three cases of gastric lymphoid hyperplasia. A pronounced T lymphoid reaction, mainly of the T helper phenotype, occurred in both lesions. Most of these T ...

Epithelioid hemangioendothelioma is an uncommon vascular tumor of intermediate malignant potential. Hepatic epithelioid hemangioendothelioma (HEHE), a rare sarcoma of the liver, usually appears as multiple nodules involving both hepatic lobes, and can be misdiagnosed as metastatic carcinoma on the basis of its radiologic manifestations. HEHE is composed of neoplastic endothelial cells that clos...

PURPOSE To describe the clinical stages and management of Achromobacter xylosoxidans keratitis with post-LASIK epithelial ingrowth in two patients. METHODS Retrospective chart review. RESULTS Both patients had been treated with topical antibiotics and corticosteroids for several weeks prior to presentation. Examination at presentation revealed significant areas of epithelial ingrowth withou...

the concept of fuzzy soft γ-ring is introduced; and some properties of fuzzy soft γ-rings are given. then the definitions of fuzzy soft γ-ideals are proposed and some of their theories are considered.

Purpose: Although tumor-infiltrating lymphocytes (TIL) have been associated with response to neoadjuvant therapy, measurement typically is subjective, semiquantitative, and unable to differentiate among subpopulations. Here, we describe a quantitative objective method for analyzing lymphocyte subpopulations and assessing their predictive value. Experimental Design: We developed a quantitative i...
