BACKGROUND: Tenosynovial giant cell tumor (TSGCT), also known as giant cell tumor of tendon sheath or pigmented villonodular synovitis, is the most common benign tumor of the tendon and synovium. The intra-articular diffuse type can present as a large infiltrative mass involving adjacent soft tissue and sometimes causes secondary destruction of bone, which leads to radiographic and clinical concern for malignancy. The tumor may also be purely extra-articular. CASE: Here, we report the fine needle aspiration cytology findings of 2 cases of diffuse-type TSGCT with large mononuclear cells with eccentric nuclei, finely granular cytoplasm, and a peripheral well-defined cytoplasmic rim of hemosiderin ("ladybird cells")...

PURPOSE: To describe a patient presenting with suspected giant cell (temporal) arteritis (GCA) in whom subsequent temporal artery biopsy showed luminal narrowing by medial calcification, metaplastic ossification, and fibrointimal proliferation, consistent with calciphylaxis. METHODS: A 55-year-old man with end-stage renal disease presented with unilateral loss of vision and elevated erythrocyte sedimentation rate and was initially treated as though he had GCA; however, a subsequent temporal artery biopsy showed marked luminal narrowing by medial calcification, metaplastic ossification, and fibrointimal proliferation, consistent with calciphylaxis...

Haemic neoplasia (HN) in bivalves has been reported in association with mass mortality events in various species of molluscs. The aim of this work was to quantify the nuclear morphometry and DNA content of neoplastic cells of mussels Mytilus galloprovincialis affected by HN using nuclear densitometry in Feulgen-stained preparations. The results were also compared with a population of normal mussel haemocytes. We captured 256 images of 3 different neoplasia stages and 120 images of normal haemocytes; thus, a total of 120,166 nuclei were analysed...

Adult xanthogranulomatous disease of the orbit refers to a heterogeneous group of clinical syndromes with differing degrees of systemic involvement and distinct prognoses. The different syndromes all present clinically with progressively enlarging, yellowish lesions of the orbit. Histologically, the lesions are characterized by an inflammatory infiltrate of foam cells and Touton-type multinucleated giant cells. The xanthomatized histiocytes are CD68(+), S100(-), and CD1a(-). There are 4 clinical forms of xanthogranulomatous disease of the orbit: adult xanthogranulomatous disease of the orbit, adult onset asthma and periocular xanthogranuloma, necrobiotic xanthogranuloma, and Erdheim-Chester disease...

A 45 year-old-man was admitted to our hospital because of discomfort in his left scrotum. He had a left testicular tumor. We performed high orchiectomy and pathological findings revealed testicular cancer. He was treated with bleomycin, etoposide and cisplatin. Computed tomography showed a new mass in the left lung after 3 cycles of the chemotherapy. Because of its rapid growth, the tumor was thought to be a metastasis lesion of testicular cancer or pulmonary infection. Transbronchial lung biopsy showed an invasion of multinucleated giant cells and granuloma...

Actinic granuloma and annular elastolytic giant cell granuloma are variants of granuloma annulare affecting, respectively, sun-exposed and sun-covered skin sites on where, besides classical findings, abundant elastophagocytosis is observed. Here, we report a case of exuberant actinic granuloma annulare that, in addition to extensive scarring, showed multiple overlying open comedones. Markedly dilated follicular infundibula filled with compact masses of laminated keratinous material were observed in proximity to dermal inflammation composed of many histiocytes and multinucleated giant cells in close association with degenerated elastic fibers and abundant elastophagocytosis...

Xanthomatous lesions of the sellar region have traditionally been divided into two separate categories, xanthomatous hypophysitis (XH) and xanthogranuloma (XG) of the sellar region. The seminal paper on XH, a condition typified by foamy histiocytes and lymphoplasmacytic infiltrates in the pituitary gland/sellar region, but usually little or no hemosiderin pigment, detailed 3 patients. However, most reports since that time have been single cases, making understanding of the entity difficult. In contrast, the seminal report on XG, characterized by sellar region cholesterol clefts, lymphoplasmacytic infiltrates, marked hemosiderin deposits, fibrosis, multinucleated giant cells around cholesterol clefts, eosinophilic granular necrotic debris, and accumulation of macrophages, included 37 patients, allowing more insights into etiology...

BACKGROUND: Hyaline ring granuloma (HRG) of the oral cavity is an uncommon disorder considered to be a foreign-body reaction resulting from implantation of food vegetable particles. Microscopically, it is characterized by the presence of structures of hyaline rings in an inflamed fibrous tissue background, which contains multinucleated giant cells. MATERIAL AND METHODS: We present the case of a 4-year-old boy diagnosed with a mandible osseous HRG, which showed clinical and tomographic aspects suggestive of an aggressive bone tumor...

Loss of wild-type p53 function is widely accepted to be permissive for the development of multinucleated giant cells. However, whether therapy-induced multinucleation is associated with cancer cell death or survival remains controversial. Herein, we demonstrate that exposure of p53-deficient or p21(WAF1) (p21)-deficient solid tumor-derived cell lines to ionizing radiation (between 2 and 8 Gy) results in the development of multinucleated giant cells that remain adherent to the culture dish for long times post-irradiation...

INTRODUCTION: Giant cell tumors of soft tissue (GCTs) are a relatively rare entity. It is a distinct but uncommon group of neoplasms morphologically identical to osseous giant cell tumor. The diffuse type of extra-articular GCT arising within muscle is a rare benign soft tissue tumor with a wide spectrum of clinical presentation. PRESENTATION OF CASE: This article reports a rare case of a 44-year-old woman with a mass arising from her right thigh. MRI showed only a few areas of low T2 signal in a mass that was hyper intense to muscle...

BACKGROUND: Multinucleated giant cell (MGC) reactions have been identified in several malignancies, but their frequency and significance in lower lip squamous cell carcinoma (SCC) are not established. This study evaluated the MGC reactions and their association with clinicopathological parameters in lower lip SCCs. The polarization profile of these cells (M1 or M2 macrophages) was also assessed. METHODS: The presence and distribution of MGC reactions in high-power fields (400×) were evaluated in hematoxylin/eosin-stained histological sections of 91 lower lip SCCs...

BACKGROUND: Liquid nitrogen has been used as adjuvant cryotherapy for treating giant cell tumor (GCT) of bone. However, the liquid phase and ultrafreezing (-196° C) properties increase the risk of damage to the adjacent tissues and may lead to perioperative complications. A novel semisolid cryogen, freezing nitrogen ethanol composite, might mitigate these shortcomings because of less-extreme freezing. We therefore wished to evaluate freezing nitrogen ethanol composite as a coolant to determine its properties in tumor cryoablation...

AIMS: The objective of this study is to describe shared morphological features of peripheral giant cell granuloma (PGCG) and peripheral ossifying fibroma (POF) in detail and discuss the possible relationship between them. MATERIALS AND METHODS: Ten intermediate cases with features resembling to both POF and PGCG were selected and type 3 and 1 collagen immunostainings were performed for evaluation of the connective tissue maturation. Immunohistochemical staining percentage (SP) for stromal cells in the slides of POF and PGCG counterparts of intermediate lesions was scored as 1 when the SP was above 10%, 2 when the SP was above 25%, 3 when the SP was above 50% and 4 when the SP was above 75%...

Aging is a complex irreversible process which leads to decline in body physiology including reproductive activity. Neurological and brain functions defects have been studied in the d-gal induced aging rodent model. However, there is dearth of literature on reproductive aging induced by d-gal treatment. Visfatin is an adipokine which regulates testicular steroidogenesis and its level increases under stress conditions to cope and extend longevity. To the best of our knowledge the expression and localization pattern of visfatin and histological evaluation of d-gal induced aged testis have not been investigated...

Amyloid-β related angiitis (ABRA) is a rare complication of cerebral amyloid angiopathy in which amyloid-β (Aβ) deposition in the leptomeningeal and cortical vessels is associated with vasculitis characterized by transmural lymphohistiocytic, often granulomatous, inflammation. Patients usually present with acute to subacute cognitive dysfunction, headaches, and focal neurologic deficits. We report two cases of ABRA with unusual clinical presentations, including one case with fatal cerebral edema leading to herniation and Duret hemorrhages, and another associated with both lobar and deep parenchymal hemorrhages with intraventricular extension as well as hypercoagulability...

Intralymphatic histiocytosis (ILH) is a peculiar pathological process characterized by the collections of benign histiocytes in dilated lymph vessels. Although the majority of ILH patients present clinically with various forms of cutaneous manifestation, rare extracutaneous incidences have been reported in the literature. To date, ILH has not been described in an internal visceral organ. We report the case of a 68-year-old woman who underwent an appendectomy during a surgical procedure for a primary peritoneal high-grade, poorly differentiated adenocarcinoma of Müllerian origin...

Stimulation of peripheral nerves has transiently restored lost sensation and has the potential to alleviate motor deficits. However, incomplete characterization of the long-term usability and bio-integration of intra-neural implants has restricted their use for clinical applications. Here, we conducted a longitudinal assessment of the selectivity, stability, functionality, and biocompatibility of polyimide-based intra-neural implants that were inserted in the sciatic nerve of twenty-three healthy adult rats for up to six months...

Juvenile xanthogranuloma is a bening pathology and it represents the most common form of non-Langerhans cell histiocytosis. It is characterized by the presence of papules or firm nodules of a pinkish or yellow-brownish nature, which mainly compromise the skin and, exceptionally, other organs. It is a self-limited entity having a spontaneous regression during the first five years of life. We report the case of a one-month-old patient who presented a congenital tumor in the abdomen, whose histopathology showed the presence of multinucleated giant Touton cells, which are typical of this pathology...
