ABSTRACT Brenner tumors are rare ovarian tumors accounting for 2-3% of all ovarian neoplasms and about 2% of these tumors are borderline (proliferating) or malignant. These tumors are commonly seen in 4th-8th decades of life with a peak in late 40s and early 50s. Benign Brenner tumors are usually small, <2cm in diameter and often detected incidentally during surgery or on pathological examination. Authors report a case of a large, calcified benign Brenner tumor in a 55-year-old postmenopausal woman who presented with complaint of abdominal pain and mass in abdomen. Imaging revealed large complex solid cystic pelvic mass -peritoneal fibrosarcoma. She underwent laparotomy which revealed huge Brenner tumor weighing 9kg arising from left uterine cornual end extending up to epigastric region. -

Diagnostic Immunohistochemistry for Canine Cutaneous Round Cell Tumours — Retrospective Analysis of 60 Cases
FOLIA HISTOCHEMICA ORIGINAL PAPER ET CYTOBIOLOGICA Vol. 57, No. 3, 2019 pp. 146–154 Diagnostic immunohistochemistry for canine cutaneous round cell tumours — retrospective analysis of 60 cases Katarzyna Pazdzior-Czapula, Mateusz Mikiewicz, Michal Gesek, Cezary Zwolinski, Iwona Otrocka-Domagala Department of Pathological Anatomy, Faculty of Veterinary Medicine, University of Warmia and Mazury in Olsztyn, Olsztyn, Poland Abstract Introduction. Canine cutaneous round cell tumours (CCRCTs) include various benign and malignant neoplastic processes. Due to their similar morphology, the diagnosis of CCRCTs based on histopathological examination alone can be challenging, often necessitating ancillary immunohistochemical (IHC) analysis. This study presents a retrospective analysis of CCRCTs. Materials and methods. This study includes 60 cases of CCRCTs, including 55 solitary and 5 multiple tumours, evaluated immunohistochemically using a basic antibody panel (MHCII, CD18, Iba1, CD3, CD79a, CD20 and mast cell tryptase) and, when appropriate, extended antibody panel (vimentin, desmin, a-SMA, S-100, melan-A and pan-keratin). Additionally, histochemical stainings (May-Grünwald-Giemsa and methyl green pyronine) were performed. Results. IHC analysis using a basic antibody panel revealed 27 cases of histiocytoma, one case of histiocytic sarcoma, 18 cases of cutaneous lymphoma of either T-cell (CD3+) or B-cell (CD79a+) origin, 5 cases of plas- macytoma, and 4 cases of mast cell tumours. The extended antibody panel revealed 2 cases of alveolar rhabdo- myosarcoma, 2 cases of amelanotic melanoma, and one case of glomus tumour. Conclusions. Both canine cutaneous histiocytoma and cutaneous lymphoma should be considered at the beginning of differential diagnosis for CCRCTs. While most poorly differentiated CCRCTs can be diagnosed immunohis- tochemically using 1–4 basic antibodies, some require a broad antibody panel, including mesenchymal, epithelial, myogenic, and melanocytic markers. -

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -

S3.02 The histological type and subtype of the tumour must be documented wherever possible. CS3.02a Accepting the limitations of sampling and with the use of diagnostic common sense, tumour type should be assigned according to the WHO system 17, wherever possible. (See Appendix 4 for full list). CS3.02b If precise tumour typing is not possible, generic descriptions to describe the tumour may be useful (eg myxoid, pleomorphic, spindle cell, round cell etc), together with the growth pattern (eg fascicular, sheet-like, storiform etc). (See G3.01). CS3.02c If the reporting pathologist is unfamiliar or lacks confidence with the myriad possible diagnoses, then at this point a decision to send the case away without delay for an expert opinion would be the most sensible option. Referral to the pathologist at the nearest Regional Sarcoma Service would be appropriate in the first instance. Further International Pathology Review may then be obtained by the treating Regional Sarcoma Multidisciplinary Team if required. Adequate review will require submission of full clinical and imaging information as well as histological sections and paraffin block material.

THE AMERICAN JOURNAL OF CANCER A Continuation of The Journal of Cancer Research ~ VOLUMEXXXIV DECEMBER,1938 NUMBER4 SYNOVIAL SARCOMAS IN SEROUS BURSAE AND TENDON SHEATHS PROF. LOUIS BERGER, M.D. (From the Pathological Department, HBpital de I'Enfant-Jdsus, and the Anti-Cancer Center of Lava1 University, Quebec) Progress in the knowledge of malignant tumors arising from synovial tissue has been slow. In spite of some recent and valuable contributions, this chapter is far from complete. The reasons for this are threefold: first, the want of knowledge concerning the normal features and nature of synovial tissue, which was long studied in articulations only, although it is common, also, to serous bursae and tendon sheaths; second, the relative-perhaps only apparent-rarity of cases; finally, the lack of precision and even vagueness of the reports in the literature., Most of the older authors, and even some contemporary ones, interested primarily in the clinical or surgical aspects of the question, have been satisfied with a purely topographical diagnosis and have either neglected the histologic aspects of their tumors or described them only briefly and superficially. We have had the opportunity of studying five cases of synovial sarcoma, differing more or less from one another but all originating outside of articu- lations, that is in serous bursae or tendon sheaths, where these tumors are less known, but perhaps easier to study than in the more intricate tissues of the joints. THENORMAL SYNOVIAL TISSUE The prototype of synovial tissue is encountered in the synovial membranes of the joints, but all histologists admit that the lining tissue of the serous bursae and tendon sheaths is homologous with articular synovialis.
