    *Institute of Pathology ††Department of Hand & Plastic Surgery, University Hospital, Erlangen **Institute of Pathology ‡‡Department of Orthopedic & Traumatology, Section for Tumor Orthopedics, University Hospital, Bonn, Germany †Department of Pathology, Faculty of Medicine in Pilsen, Charles University, Prague ‡Biomedical Center of the Faculty of Medicine in Pilsen, Pilsen, Czech Republic §Department of Pathology, University of Pittsburgh Medical Center, Presbyterian Hospital, Pittsburgh, PA ∥Department of Pathology, National University Health System, Singapore ¶Department of Pathology, 3rd Medical Faculty in Prague, Charles University, Prague, Czech Republic.
    Phosphaturic mesenchymal tumor (PMT) is a rare neoplasm of uncertain histogenesis that has been linked to tumor-induced osteomalacia (TIO) since 1959. The neoplastic cells produce increased amount of FGF23 which results in TIO via uncontrolled renal loss of phosphate (phosphaturia), and consequently diminished bone mineralization. To date, ∼300 cases have been reported. Read More

    [Granulomatous reaction pattern of the skin : Interstitial granulomatous dermatitis - lymphoma - vasculitis].
    Hautarzt 2017 Jun 12. Epub 2017 Jun 12.
    Konsultations- und Referenzzentrum für Vaskulitis-Diagnostik, MVZ am Marienkrankenhaus gGmbH, Hamburg, Deutschland.
    A particular diagnostic situation in the classification of a granulomatous dermatitis results when no circumscribed granulomas but instead a diffuse interstitial histiocytic inflammatory infiltrate, a granulomatous vasculitis or a neoplastic lymphocytic infiltrate is found. Interstitial granulomatous dermatitis was originally described in patients with arthritis. Later, it was recognized that there are also associations with other usually immunological diseases.

    [Giant cell-rich lesions of bone and their differential diagnosis].
    Cesk Patol 2017 ;53(2):61-70
    Giant cell-rich lesions form a heterogeneous group of reactive and truly neoplastic processes with diverse clinical presentation and biological behavior. Common to all of them are variably numerous multinucleated osteoclast-like giant cells and the presence of mononuclear stroma. Based on the histological picture alone it is sometimes impossible to reliably distinguish certain tumors from each other. Read More

    Cholesterol Granuloma of the Abdominal Wall: An Unusual Finding in the Setting of Renal Cell Carcinoma.
    Urol Case Rep 2017 Jul 29;13:160-161. Epub 2017 May 29.
    University of Texas Medical Branch, Department of Surgery, Division of Urology, 301 University Blvd, Galveston, TX 77555-0764, USA.
    Cholesterol granulomas are composed of a distinct type of granulation tissue that contains lipids and cholesterol crystals. They are not believed to be a pathological entity, but rather an inflammatory tissue reaction to the presence of trapped blood secondary to localized hemorrhage.(1) Cholesterol granulomas can be identified histologically by the presence of multi-nucleated giant cells, hemosiderin, and red blood cells along with their associated break-down products.

    Benign Bone Conditions That May Be FDG-avid and Mimic Malignancy.
    Semin Nucl Med 2017 Jul 12;47(4):322-351. Epub 2017 Apr 12.
    Department of Radiology and Nuclear Medicine, Deventer Ziekenhuis, Deventer, The Netherlands.
    Positron emission tomography with the radiotracer (18)F-fluoro-2-deoxy-d-glucose (FDG) plays an important role in the evaluation of bone pathology. However, FDG is not a cancer-specific agent, and knowledge of the differential diagnosis of benign FDG-avid bone alterations that may resemble malignancy is important for correct patient management, including the avoidance of unnecessary additional invasive tests such as bone biopsy. This review summarizes and illustrates the spectrum of benign bone conditions that may be FDG-avid and mimic malignancy, including osteomyelitis, bone lesions due to benign systemic diseases (Brown tumor, Erdheim-Chester disease, Gaucher disease, gout and other types of arthritis, Langerhans cell histiocytosis, and sarcoidosis), benign primary bone lesions (bone cysts, chondroblastoma, chondromyxoid fibroma, desmoplastic fibroma, enchondroma, giant cell tumor and granuloma, hemangioma, nonossifying fibroma, and osteoid osteoma and osteoblastoma), and a group of miscellaneous benign bone conditions (post bone marrow biopsy or harvest status, bone marrow hyperplasia, fibrous dysplasia, fractures, osteonecrosis, Paget disease of bone, particle disease, and Schmorl nodes).

    Mycolates of Mycobacterium tuberculosis modulate the flow of cholesterol for bacillary proliferation in murine macrophages.
    J Lipid Res 2017 Apr 13;58(4):709-718. Epub 2017 Feb 13.
    Laboratory of Molecular Immunology, Department of Biomedical Molecular Biology, Ghent University, Ghent Zwijnaarde 9052, Belgium
    The differentiation of macrophages into lipid-filled foam cells is a hallmark of the lung granuloma that forms in patients with active tuberculosis (TB). Mycolic acids (MAs), the abundant lipid virulence factors in the cell wall of Mycobacterium tuberculosis (Mtb), can induce this foam phenotype possibly as a way to perturb host cell lipid homeostasis to support the infection. It is not exactly clear how MAs allow differentiation of foam cells during Mtb infection. Read More

    Central giant cell granuloma (CGCG) is an uncommon benign intraosseous lesion of the jaw, found predominantly in children and young adults below 30 years of age. The purpose of this article was to present a summary of the current literature and a case report of an 11-year-old boy diagnosed with an aggressive CGCG involving the anterior maxilla that was removed in 2004 and subsequently recurred almost 3 years later in 2006. The presenting features of the patient and the effect of combined surgical and orthodontic treatment for this condition are discussed. Read More

    Central giant cell granuloma is a benign, aggressive neoplasm composed of multinucleated giant cells that almost exclusively occurs in the jaws though extra- gnathic incidence is rare. Multifocal CGCGs of the jaws are very rare and suggestive of systemic diseases such as hyperparathyroidism, an inherited syndrome such as Noonan- like multiple giant cell lesion syndrome or other disorders.Very few cases of multifocal CGCGs in the jaws without any concomitant systemic disease have been reported.

    The anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitides (AAV) are a heterogeneous group of diseases causing inflammation in small blood vessels and linked by the presence of circulating ANCA specific for proteinase 3 (PR3) or myeloperoxidase (MPO). These antigens are present both in the cytoplasmic granules and on the surface of neutrophils, and the effect of ANCA on neutrophil biology has been extensively studied. In contrast, less attention has been paid to the role of monocytes in AAV. Read More

    [Giant inflammatory pseudotumor of the cranial base].
    Neurocirugia (Astur) 2016 Nov - Dec;27(6):291-295. Epub 2016 Jul 12.

    The inflammatory pseudotumour (IPT) is a non-neoplastic entity of unknown origin, and is characterised by a proliferation of connective tissue and a polyclonal inflammatory infiltrate. Central nervous system involvement is uncommon, and usually represents a diagnostic and therapeutic challenge even for the experienced clinician. This reports deals with the case of a 56year-old woman diagnosed with a giant, infiltrating mass centred in the left cavernous sinus, who had a rapid clinical and radiological response to steroid therapy.

    Sarcoidosis is a systemic inflammatory disorder characterized by non-caseating granulomas, predominantly involving lung, mediastinal lymph nodes and other organs. Synovium involvement is infrequent, and as far as we know, involvement of a periprosthetic membrane has not been reported in the English literature. Intra-articular diffuse tenosynovial giant cell tumor ("conventional diffuse pigmented villonodular synovitis") is an uncommon, locally aggressive neoplasm with few previous case reports in which it arose in periprosthetic tissues after knee arthroplasty.
