Multinucleate Cells

Background There are less than 100 cases of multinucleate cell angiohistiocytoma (MCA) currently reported in the literature. It occurs as a localized, asymptomatic, benign proliferation of the skin, characterized histologically by irregular multinucleate cells. Due to its novelty, the etiology of the disease and treatment options are still under investigation. Objective To report a case of confirmed, generalized MCA along with a review of the literature on the histology, immunology, potential etiology, and treatment of MCA. Observations The patient was a 41-year-old female with asymptomatic violaceous plaques found on the extensor arms, legs, and trunk. Histopathology revealed increased dilated vascularity and cellularity (composed of mononuclear histiocytes and a few angulated multinucleated giant cells) in the dermis. Conclusions Overall, MCA is a poorly understood, distinct dermatologic phenomenon. Here we present a case of generalized MCA to further the understanding of this disease presentation.

Abstract We report a new case of aneurysmal bone cyst of the larynx occurring in a 22-year-old man. The lesion manifested with progressive breathing discomfort and appeared as a polypoid pedunculated mass attached to the subglottic mucosa. Microscopically, it featured numerous mononuclear and multinucleated giant cells surrounding cavernous spaces filled with blood. Foci of proliferating spindle cells and mature osteoid tissue could be recognized. There was no apparent relationship with the cricoid perichondrium. Clinical follow-up was negative for local recurrence. Based on this report and a review of the literature, we conclude that aneurysmal bone cyst of the larynx is phenotypically comparable to its bone homologue; however, its microscopic recognition may be difficult, especially on small biopsy fragments. Since it can be confused with several lesions, including telangiectatic osteosarcoma, awareness of this rare appearance of aneurysmal bone cyst is important to avoid unnecessary radical surgery.

A review of the literature devoted to eye sarcoidosis is presented. Sarcoidosis is a systemic granulomatous disease of unknown etiology, with a pathognomonic feature of non-caseous granuloma formed mainly by epithelium cells and single Langhans giant cells. Sarcoidosis has many synonyms: Besnier-Boeck-Schaumann disease, benign Schaumann’s granulomatosis, nodular reticular disease. Primary targets of sarcoidosis are lungs, intrathoracic lymph nodes, eyes and skin. During the last years eye sarcoidosis is registered more frequently, that is probably associated with better diagnosis. The frequency of the eye involvement in patients with sarcoidosis, according to different authors, is 5-69% (3rd or 4th among all the target organs involved). The eye manifestations of sarcoidosis are multiple with the uvea most frequently affected, especially iris and ciliary body. The involvement of the back of the eye includes granulomatous uveitis, vitreitis, periphlebitis. It is worth noticing that only minor non-granulomatous precipitates can be found in the acute stage of the disease. In case of chronic inflammatory process, precipitates become granulomatous. The treatment can influence both precipitates’ size and shape. In case of termination of the inflammation, precipitates are undergoing a complete resorption or decrease in size, become pigmented of transparent («precipitate shades»). The feature of sarcoidosis is the tendency to comissure formation, the pupil is hardly dilated by medicines, leading to the secondary glaucoma. Conjunctiva, extraocular muscles, retroocular tissues, lacrimal gland can be involved, as well as the optic nerve, chiasma, leading to meningovascular infiltrates formation. When diagnosed, a complex treatment with topic, symptomatic drugs and the drugs with the systemic action is used. The search of new effective treatment options is still ongoing.

The authors report on two cases of pineal germinomas with granulomatous inflammation (granulomatous germinomas). Macroscopically, both tumors were relatively hard and grayish in color. Histological examination revealed a germinoma with multinucleated giant cells and Schaumann bodies in one case, and a germinoma with the background of acellular fibrillated matrix in the other. On immunohistochemical analysis, the granulomatous germinomas were shown to contain many macrophages, T- and B-lymphocytes, and glial fibrillary acid protein-positive cells infiltrating the specimens, compared to nongranulomatous germinomas. Analysis of Masson's trichrome staining tests showed that large areas of the granulomatous germinomas were occupied by a collagenous component; this was not the case in cases of nongranulomatous germinomas. Analysis of monoclonal anti-human Ki-67 results showed that the granulomatous germinomas had a lower score than nongranulomatous germinomas (p < 0.05, unpaired t-test), indicating that germinomas with granulomatous inflammation may have a better prognosis.

A 57-year-old Japanese man was admitted to the hospital with back pain and fever, multiple lung nodules, and abdominal aortic aneurysm (AAA). Laboratory tests performed at admission showed an increased proteinase 3 anti-neutrophil cytoplasmic antibody (PR3-ANCA) level. Video-associated thoracoscopic lung biopsy was performed; pathologic examination showed granulation tissue with necrosis and multinucleated giant cells. The diagnosis of granulomatosis with polyangiitis (GPA) was confirmed on the basis of the clinical presentation, laboratory findings, and lung biopsy. All symptoms were ameliorated, and the serum level of PR3-ANCA declined following treatment with prednisolone and cyclophosphamide. Although the association of GPA with AAA is rare, GPA may be included among the large vessel vasculitides that can give rise to aortic aneurysm.

Tenosynovial Giant Cell Tumor

Introduction: Tenosynovial giant cell tumor (TSGCT) (synonym – pigmented villonodular synovitis) – is a rare benign proliferative lesion of the synovial sheath, localized in the joint capsule, bursa or tendon sheath and characterized by locally destructive growth. Depending on the prevalence within the joint elements, the presence of a capsule around the tumor, histophotographic features of cell structure and clinical behavior TSGCT can be divided to localized or diffuse type. The aim of the study was researching of histopathological properties of diffuse-type TSGCT, determine the parameters its morphological indicators and to find out the correlation between these morphological and clinical parameters. Materials and methods: The research material was used biopsy (resect) of pathological lesions from 50 patients who were diagnosed and histologically verified diffuse-type TSGCT. Microscopic examinations of the stained sections and their photo archiving were carried out with use of a Olympus-CX 41 light optical microscope. Group measurable parameters (mean values and Pearson tetrachoric index (association coefficient) were calculated in groups of comparison for morphological and clinical indices of TSGCT. The mean values were compared by Student’s test, P value of ≤0.1 was considered statistically significant. Results:Correlation analysis of indicators that accounted for the pairs of cases «clinic – morphology» revealed the relationships, that had the highest parameters of the association coefficient between such indicators: «presence of villous growths» - «severity of hemosiderosis» (if hypertrophied synovial villi available, with vascular injection and pronounced proliferation of synovial cells, there is also a significant accumulation of hemosiderin pigment); «presence of villous growths» - «type of predominant cellular proliferates» (if cells of TSGCT diffuse type consists of monotonous sheets of stromal cells, with uniform, oval to reniform nuclei, the proliferation of villi in synovial layer is non-distinctive); «presence of nodes» - «kind of stroma» (if nodes predominate, their histological structure is mainly represented by polymorphic clusters of synovitis cells in the form of cells, strands, chains, solid formations, among immature connective tissue with low hyalinosis); «cell size (area, cm²)» - «severity of haemosiderosis» and «cell size (area, cm²)» - «the number of multinucleated giant cells» (there is a pronounced deposition of pigment and accumulation of osteoclast-like multinucleated giant cells type, although usually their number is relatively small compared to the localized type of TSGCT). Conclusions: Morphological parameters, that we have identified, characterize pathological changes in the tissues of TSGCT; careful analysis of the frequency of their occurrence in the different comparison groups made it possible to establish intergroup differences and correlations between individual indicators, which were previously unknown or not obvious. Our study was determine to analyze of incidence rates and correlation relationships, revealed some previously unknown differences and dependencies that are important for understanding the pathogenesis, improvement of diagnosis and prognosis of diffuse-type TSGCT.

Abstract Background Entero-colovesical fistula is a rare complication of various benign and malignant diseases. The diagnosis is prominently based on clinical symptoms; imaging studies are necessary not only to confirm the presence of the fistula, but more importantly to demonstrate the extent and the nature of the fistula. There is still a lack of consensus regarding the if, when and how to repair the fistula. The aim of the study is to review the different surgical treatment options, focus on surgical indications, and explore cumulative recurrence, morbidity, and mortality rates of entero-vesical and colo-vesical fistula patients. Methods A systematic review of the literature was conducted according to PRISMA guidelines. Random effects meta-analyses of proportions were developed to assess primary and secondary endpoints. I2 statistic and Cochran’s Q test were computed to assess inter-studies’ heterogeneity. Results Twenty-two studies were included in the analysis with a total of 861 patients. Meta-analyses of proportions pointed out 5, 22.2, and 4.9% rates for recurrence, complications, and mortality respectively. A single-stage procedure was performed in 75.5% of the cases, whereas a multi-stage operation in 15.5% of patients. Palliative surgery was performed in 6.2% of the cases. In 2.3% of the cases, the surgical procedure was not specified. Simple and advanced repair of the bladder was performed in 84.3% and 15.6% of the cases respectively. Conclusions Although burdened by a non-negligible rate of complications, surgical repair of entero-colovesical fistula leads to excellent results in terms of primary healing. Our review offers opportunities for significant further research in this field. Level of Evidence Level III according to ELIS (SR/MA with up to two negative criteria).
