Abstract
OBJECTIVE To review the clinical, morphologic, immunohistochemical, and histogenetic characteristics of dermatofibrosarcoma protuberans with areas of giant cell fibroblastoma and explore current treatment options. METHODS We describe the case of a 38-year-old patient with a tumor measuring 5.7 cm on the right labium majus of the vulva. Serial sections stained with hematoxylin-eosin were examined and immunohistochemical staining was performed for CD34 and PDGF receptor alpha and beta (PDFGRA and PDGFRB). RESULTS The histologic study showed spindle-cell proliferation typical of dermatofibrosarcoma protuberans and other areas containing fibrosis and giant cells lining pseudovascular spaces. Both tumor areas expressed CD34, PDGFRA, and PDGFRB. CONCLUSIONS Only two cases of dermatofibrosarcoma protuberans with areas of giant cell fibroblastoma in the vulva have been reported to date. Both dermatofibrosarcoma protuberans and giant cell fibroblastoma are characterized by the translocation t (17;22) (q22;q13). The fact that PDGFRA and PDGFRB are overexpressed in these tumors opens new treatment options with imatinib. Surgical excision with wide margins or Mohs micrographic surgery continues to be the treatment of choice.

Abstract
Giant cell tumors are commonly found over the flexor tendon sheath of the hand and wrist. However, giant cell tumors in the knee joint are rare, especially in children. We report an interesting case of an 11-year-old girl who presented with a painful lump on her right knee that enlarged over time. Clinically, she had fullness over the anterolateral part of her knee. Magnetic resonance imaging revealed an encapsulated mass inferior to the patella. The tumor measured 3 x 3.5 x 1.5 cm. Histopathological findings confirmed that it was a tenosynovial giant cell tumor. Because of initial mild symptoms, there was a delay of 2 years from the initial symptoms until tumor excision. Her follow-up period was 35 months, and her health to date is excellent with no recurrence. We believe that reporting this rare case will help clinicians update their knowledge on possible causes of lumps in the knee, and avoid diagnostic delay. It could also prove to be beneficial in arriving at a diagnosis in future cases.

Abstract
There are more diffuse giant cell tumours of the tendon sheath than we had expected, and we recommend excising them microscopically. We have treated 18 patients since 1988. They had two types of tumour: 10 nodular, and eight diffuse. We used a microscope to excise diffuse tumours. In the only case in which we did not use a microscope for a diffuse tumour, the tumour recurred. It spread to an adjacent joint in six diffuse tumours, but no nodular tumours. The detection of diffuse lesions was difficult without a microscope.

Abstract
BACKGROUND This study was performed to evaluate the usefulness of high-resolution grayscale and color Doppler ultrasound to distinguish benign from malignant soft-tissue masses on the basis of ultrasonographic patterns. METHODS We enrolled 398 female and 420 male patients aged 1-104 years (mean, 49.8 years). All presented with a palpable nodule or mass located superficially in the body. Each lesion was examined by grayscale and color Doppler ultrasonography to assess its echogenicity, margin, shape, composition, acoustic transmission, size and other patterns. Spectral Doppler was applied in lesions with positive color flow signals. The nature of all masses was confirmed by aspiration cytology, biopsy, surgical pathology or long-term clinical follow-up. RESULTS There were a total of 693 benign and 125 malignant masses. Five malignant and 14 benign histologies (including 6 types with inflammation-related, hematoma or pseudoaneurysm) occurred that had more than 10 subjects with each histology. Eight benign histopathologies included cysts, neoplasms, vascular and miscellaneous. Five malignant histologies included metastases, osteogenic sarcomas, lymphomas, malignant fibrous histiocytomas and liposarcomas. There were significant differences (p < 0.05) between the benign and malignant soft-tissue tumors in terms of parameters including tumor margin, shape and size. Benign lesions did not have infiltrated margins or a scalloped shape and malignant tumors tended to be large. However, there was no significant difference (p > 0.05) between the benign and malignant soft-tissue tumors in terms of echogenicity, composition and color Doppler features. CONCLUSION Ultrasonography with color Doppler imaging is a good modality for characterizing most soft-tissue masses, and tumor size > 5 cm and having infiltrated margin highly suggests malignancy.

Abstract
Giant cell tumour of soft part is a very rare neoplasm. The majority of these tumours are located superficially (in subcutaneous tissue) and occur in the proximal parts of the extremities. The deep-situated giant cell tumours of the neck are extremely rare. That is why we report a case of primary giant cell tumour of soft part localized in the trapezius muscle of a 19-year-old woman. We present both cytological and histological picture of the neoplasm. The cytological image of the smear is so representative that the proper diagnosis can be settled basing on the fine-needle aspiration cytology.

Abstract
The giant cell tumor of the tendon sheath is regarded as one of the most common neoplasms of the hand. This tumor usually manifests itself as a localized, solitary, painless and palpable subcutaneous nodule on the palmar aspect of a digit. A multifocal origin of the tumor has rarely been reported in the literature before. In this article we present a case of a giant cell tumor of the tendon sheath, in which two separate lesions developed simultaneously on the same tendon (flexor digitorum superficialis) of the little finger of the right hand together with a literature review about multifocal cases.

Abstract
INTRODUCTION The aim of this retrospective study was to study the clinical presentation, investigations, histopathological findings, and the best ways of treatment of the giant cell tumour of the tendon sheath (GCTTS). METHODS The medical records of all patients diagnosed to have GCTTS during the period 1994-2001 were reviewed, and follow-up was for three to ten years. RESULTS The total number of patients was 52, of whom 36 were females, and the mean age was 32.4 years. All the tumours except one were located in the hand and wrist area, with the thumb being the most affected finger. Painless swelling was the most common presentation. All of them were treated surgically and the recurrence rate was 24 percent. CONCLUSION After reviewing the literature and comparing with our results, we conclude that GCTTS is a true benign tumour with local aggressive behaviour in some cases, and the best way of treatment is wide local excision.

Abstract
OBJECTIVES To retrospectively study on malignant giant cell tumor of tendon sheath (MGCTTS) in the hand, and to evaluate its clinical, histologic, immunohistochemical features and biologic evolution. METHODS Between January 1991 and December 2001, 10 patients with histologically proven MGCTTS were treated. The clinical material, radiographs and hematoxylin and eosin-stained sections were reviewed. Immunohistochemical studies and nuclear suspensions for flow cytometry were done on paraffin embedded tissue. All patients were followed up. RESULTS Three of 10 patients in which the diagnosis of MGCTTS was originally considered were excluded after the slides reviewed and immunohistochemical examination performed. In the other 7 patients, one showed malignant and aggressive nature: the lesion recurred several times and the patient eventually died with pulmonary metastases. The immunohistochemical profile of the patient was similar to that reported in benign GCTTS, and the flow cytometry DNA analysis detected aneuploidy. Six cases presented histologic features of malignancy, 4 of them undertook the immunohistochemical examination and their profiles were similar to that reported in benign GCTTS. An aneuploidy DNA pattern was detected in one case on flow cytometry evaluation, diploidy DNA pattern was detected in 3 cases, and their S-phase fraction was 4.5%, 11.6% and 2.6% respectively. All of them had a benign clinical features, they were alive and without evidence of disease from 1.5 to 7.5 years (averagely, 4.5 years) after complete surgical excision or resections with wide surgical margins. None of them had received chemotherapy or radiation therapy. CONCLUSIONS Malignant giant cell tumor of tendon sheath is an extremely rare malignant tumor, some cases have a poor outcome, the others, despite the histologically malignant features, have a good prognosis if wide surgical excision ablates the tumor completely.

Abstract
OBJECTIVE To report on multinucleated giant cells (MNGCs) in salivary fine needle aspiration (FNA). STUDY DESIGN The cytologic reports of salivary gland region FNA during a 10-year period was searched using the keyword giant cell in the final diagnosis or microscopic description. Cases with foreign body-type giant cells secondary to previous biopsy or FNA were excluded. Histologic correlations and immunohistochemical staining for CD68, CK, EMA, S100, HMB45 and CD1a were performed on selected cases. RESULTS Twenty-six aspiration smears containing MNGCs were identified from 1040 salivary gland FNAs (2.5%). MNGCs were seen in some reactive or inflammatory conditions, benign neoplasms and malignant neoplasms. By type of MNGC, the salivary lesions were categorized in 3 groups: those with foreign body type, osteoclast type and tumor giant cells. CONCLUSION MNGCs can be seen in a wide spectrum of salivary gland lesions ranging from reactive to benign and malignant. They are of nonepithelial origin or can be of true neoplastic nature in metastatic lesions.

Abstract
A case of giant cell fibroblastoma in a 62-year-old male is described. The 2 x 1.5 x 1.5 cm tumor was excised from the right supraclavicular area. Histologically, it was typical with exceptions that the typical pseudovascular spaces were seen only focally and the neoplastic cells were closely spatially associated with lymphocytes and plasmocytes. This association was suggestive of emperipolesis. The unusual clinicopathologic features caused some diagnostic difficulty.

Abstract
Primary giant cell tumor of soft tissue (GCTST) arising in a finger is a rare event. We report a case of a 54-year-old man with a primary finger giant cell tumor that appeared histologically identical to giant cell tumor of bone. The patient presented with a cystic mass of the finger. The magnetic resonance imaging showed no relation between the nodule and bone, tendons or synovial tissues. The distinction of this entity from other more common primary finger tumors with giant cell morphology is emphasized.

Abstract
Giant cell tumour of bone (GCTB) is a benign bone tumour known for the unpredictable clinical behaviour of recurrences and, in rare instances, distant metastases. It consists of uniformly distributed osteoclastic giant cells in a background of mononuclear rounded and spindle-shaped cells. Cytogenetically, telomeric associations are the most common chromosomal aberrations, which, however, are normally almost exclusively found in high-grade malignancies. GCTB has often been regarded as a polyclonal tumour, but more recently a recurrent specific aberration was reported, which suggests a possible role for disturbed telomere maintenance. Here we further investigate telomere maintenance in GCTB using 19 samples from 19 patients. A combination of immunofluorescence and FISH was performed, applying antibodies directed against promyelocytic leukaemia body-related antigen and hTERT and using telomere peptide nucleic acid probes. The TRAP assay and telomere restriction fragment length analysis were performed for functional detection of telomerase activity and alternative telomere lengthening. Both osteoclastic giant cells and mononuclear cells showed positivity for hTERT and promyelocytic leukaemia body-related antigen. In most mononuclear cells, co-expression was present. The TRAP assay demonstrated heterogeneous telomerase activity, while telomere restriction fragment length analysis showed non-heterogeneous telomere lengths, indicating the absence of alternative telomere lengthening. Confocal microscopy showed stereometric co-localization of nucleolin with promyelocytic leukaemia body-related antigen in association with telomeres in the spindle-shaped cells. hTERT was more diffusely distributed throughout the nucleus. Our results show that GCTB demonstrates remarkable telomere maintenance of activated telomerase and inactivated alternative telomere lengthening in the presence of normal mean telomere restriction fragment lengths. These findings strongly suggest that these aggregates, while activating telomerase, are part of a structural telomere protective-capping mechanism rather than of a telomere-lengthening mechanism. Telomere maintenance could be considered an important key factor in the pathogenesis of GCTB.

Abstract
OBJECTIVE To correlate the cytomorphologic spectrum of giant cell tumor of tendon sheath (GCTTS) with clinical and histologic findings and determine key features helpful in preoperative diagnosis. STUDY DESIGN Retrospective analysis was done on 48 cases diagnosed cytologically over 9 years. Cases were divided into 2 groups: in group 1 cytology and histology were available (12), and in group 2 cytology alone was available (36). Cytomorphologic features were correlated with clinical and histologic findings. RESULTS Patients ranged in age from 11 to 60 years, with more women. Small joint involvement was seen in all cases except 1, with upper limb involvement in most cases. Recurrence occurred in 3 cases. Aspiration smears in all cases showed high cellularity, multinucleated osteoclastic type of giant cells and stromal cells. Other features seen less frequently were cytoplasmic granules and vacuoles, nuclear grooves, inclusions, budding, focal mild pleomorphism, hemosiderin-laden macrophages and foam cells. Mitosis and necrosis were absent. Cytologic features were classified as constant when present in all cases and variable when present occasionally. CONCLUSION The constant cytologic features when combined with clinical and radiologic details are sufficiently distinctive of GCTTS. Fine needle aspiration cytology can be used in early, accurate preoperative diagnosis.

This report describes the case of a 26-year-old woman with a recurrent extraarticular diffuse-type tenosynovial giant cell tumor (D-TGCT) of the medial region of the knee affecting the pes anserinus and hamstring tendons. Presurgical MRI did not exclude infiltrative properties of the tumor. In the histological evaluation, the tumor showed an aggressive dispersion by infiltrating the collagenous tissue of the hamstring tendons. The treatment included a resection of the pes anserinus complex with distal semitendinosus and gracilis tendons. Regarding extraarticular D-TGCT a review of the literature showed a predominant affection of the medial region of the knee and thigh.

Abstract
The final diagnosis of a bone tumour comes in many cases like the last piece of a puzzle which requires integration of clinical, imaging and pathological data. However there are situations in which a discrepancy exists between histology and imaging studies and where histology alone cannot be decisive. This paper reviews such situations.

Abstract
The authors present a case of a 42-year-old female who developed a leiomyosarcoma of the right proximal tibia that appeared radiologically similar to a giant cell tumor Histology revealed spindle cells running in whorl-like fashion with focal atypia and low mitotic figures. The immuno-stains revealed positive reactivity for alpha-smooth muscle (SMA), muscle actin and cytokeratin (AE1/AE3). The authors rendered a diagnosis of low-grade leiomyosarcoma of bone. The lesion was considered a primary lesion since the patient did not have other leiomyomatous tumors. The MRI showed hypo- to iso- signal intensity on T1-weighted imaging and heterogeneous intensity on T2-weighted imaging. This was likely due to admixed fibrotic tissue in the lesion. The tumor cells were not positive for Ebstein-Barr virus by in-situ hybridization as seen in leiomyomatous tumors in immunodeficiency patients.

Abstract
This report presents a case of widespread intramedullary giant cell ependymoma arising from the central canal of the C4 segment of the spinal cord in a 28-year-old man admitted to hospital with tetraplegia and signs of increased intracranial pressure, eight months after surgical spinal cervical decompression without tetraplegia improvement. Magnetic resonance imaging and autopsy revealed a tumour extending from segment C3/C4 of the spinal cord to the lower half of the fourth ventricle with coexisting syringomyelia. This slow-growing ependymoma of low-grade malignancy exhibited unusual morphology as well as degenerative and ischaemic changes. All intramedullary and ventricular tumour segments featured coexistence of two forms of neoplastic cell, classic ependymomal and pleomorphic multinucleated giant cells. The morphological diagnostic criteria of unusual giant-cell variant of ependymoma and tumour-related syringomyelia in adults are discussed, based on the presented case and a review of the literature.

Abstract
Primary giant cell tumor of soft tissue (GCT-ST) arising in breast is exceedingly rare. We report a case of a 60-year-old woman with a primary breast giant cell tumor that appeared histologically identical to giant cell tumor of bone and had a clinically malignant course. The patient presented with a cystic mass of the breast, suspected on imaging to be an organizing hematoma, possibly related to previous injury. Histopathological evaluation revealed a neoplasm composed of mononuclear cells admixed with osteoclast-like giant cells resembling giant cell tumor of bone. Immunohistochemical staining was positive for CD68, smooth muscle actin, and vimentin, but was negative for a panel of epithelial and additional muscle markers. These features were most consistent with GCT-ST, an uncommon neoplasm of low malignant potential. Despite aggressive surgical treatment achieving clear surgical margins, the patient expired with pulmonary metastases within a year of her initial presentation. This case demonstrates the difficulty of predicting clinical behavior of GCT-ST of breast on the basis of histological features and depth of tumor alone. To our knowledge, this is the first case report of a GCT-ST arising in the breast associated with a fatal outcome. The distinction of this entity from other more common primary breast tumors with giant cell morphology is also emphasized.

Abstract
Primary giant-cell tumor of the salivary gland is a rare lesion with an incompletely characterized histogenesis. To the best of our knowledge, only 16 cases have been previously documented in the English-language literature. We report a new case, which occurred in a 75-year-old man who presented with a parotid mass and cervical lymphadenopathy. The patient underwent a left total parotidectomy and cervical lymph node dissection. As far as we know, ours is the only reported case of a primary giant-cell tumor of the salivary gland in which the patient presented with lymph node metastasis. Because so little is known about giant-cell tumor of the salivary gland, we use the occasion of this case report to describe the cytologic, histologic, and immunohistochemical characteristics that we observed.

Abstract
Histiocytic sarcoma is an uncommon neoplasm of mature histiocytes with a poor clinical outcome. We report a case of a true histiocytic sarcoma with prominent and evenly distributed multinucleated giant cells that mimics a giant cell tumor of soft tissue. The tumor was located between the appendix, right ovary, and the terminal ileum with severe adhesion. The liver and spleen were not enlarged. Grossly, the tumor appeared grayish white, solid, and soft. Microscopically, polygonal mononuclear tumor cells aggregated to form somewhat epithelioid nests, which occasionally showed coagulative necrosis. Prominent and evenly scattered giant cells were present in all sections. In addition, tumor cell infiltration was noted in regional lymph nodes. The tumor cells were positive for lysozyme, CD68, CD163, and negative for T- and B-cell lineage markers, follicular dendritic cell, megakaryocytic, epithelial, muscular, and melanocytic markers, CD1a and CD30. This case posed great difficulty in clinical and pathological diagnoses. Gross pictures, microscopic findings, and extensive immunostains are important for the differential diagnosis.

Abstract
Giant cell tumors of tendon sheath (GCTTS) represent a localised form of pigmented villonodular synovitis. They are usually found in the hand (80% of cases) where it represents the second most common tumor of the soft parts after the ganglion cyst. Its surgical treatment is sometimes difficult because of local extension and the invasion of vital digital structures. We report a retrospective study over 10 years of 32 cases of GCTTS with an average age of 35 years and a sex-ratio of 1. The reason for consultation was the presence of a digital mass, associated with an impairment of finger flexion in 43,7% of patients. A palmar localisation was found in 56,2%, especially in the fifth ray (62,5%) and at the level of the distal phalanx (68,7%). Radiological changes were observed in 4 cases. All patients were treated surgically. Macroscopically the lesion presented as an encapsulated tumor, polylobulated and yellow-brownish which invaded the skin (1 case), extended into the sheath of the flexor tendons (3 cases) and under the extensor tendon (4 cases). In the post operative follow up we noted one case of hypoaesthesia of the pulp and three cases of stiffness of the proximal interphalangeal joint. No skin necrosis was found. With a 4 year average follow up (10 months - 9 years), we noted three reccurrences (9,3%) which were all surgically managed. After analysis of the literature, the authors will describe the clinical aspects and the therapeutic difficulties of this condition.

Abstract
BACKGROUND Giant cell fibroblastoma (GCF) is an unusual soft tissue tumor, occurring predominantly in infants and children, and rarely in adults. Giant cell fibroblastoma develops de novo in the dermis or subcutis with a predilection for the extremities, the abdominal and chest walls, umbilical and inguinal regions. CASE A GCF arose at the same site (labium majus of vulva) as a previous cellular fibroepithelial stromal polyp in a 28-year-old woman. CONCLUSION We report a case of GCF of the vulva, an unreported site.

Abstract
We report a case of primary giant cell malignant fibrous histiocytoma (GCMFH) of the breast. A 56-year-old Japanese woman presented with a firm mass in the right breast. Mammography and ultrasonography revealed a well-circumscribed and lobulated mass in the upper outer quadrant of the right breast, indicative of a benign breast tumor or mucinous carcinoma. Magnetic resonance imaging revealed a restricted breast tumor without intraductal spread. Computed tomography and bone scintigraphy found no sites of distant metastases. Fine needle aspiration biopsy showed several clusters of atypical cells associated with numerous multinucleated giant cells. Breast-conserving surgery with axillary lymph nodes dissection was performed. Histological examination showed primary GCMFH of the breast. No metastases were identified in any of the 15 left axillary lymph nodes resected and surgical margins were free from tumor cells. The tumor was negative for both estrogen and progesterone receptor. Neither adjuvant chemoendocrine therapy nor postoperative radiotherapy was given, and the patient has remained disease free for 30 months postoperatively. To our knowledge, only 30 cases of primary MFH of the breast have been reported in the literature.

Abstract
A quarter of a century ago at the International Academy of Pathology in Boston, Mass, Drs Enzinger and Shmookler's seminal abstract on giant cell fibroblastoma (GCF) included 20 GCFs on the back and thigh of mostly male children. These tumors involved dermis and subcutis, and had parallel fascicles of wavy uniform spindled cells with wiry collagen, dense sclerosis, and gaping spaces with scattered and rimming pleomorphic giant cells. EM suggested fibroblastic phenotype. All cases had benign behavior, but almost half recurred. The caveat was mistaking this tumor for a malignancy. In 1989, Drs Enzinger, Shmookler, and Weiss published this abstract as 28 cases from the AFIP (1960-1981), including 4 adults up to 55 years old. They proposed a relationship of this childhood tumor to dermatofibrosarcoma protuberans (DFSP). Since these original descriptions of GCF, there has been additional immunohistochemical and molecular support for a relationship between DFSP and GCF. We reviewed additional AFIP cases of GCF since 1981, in honor of Dr Enzinger. These new cases included 60 males and 26 females, whose ages ranged from 6 months to 62 years (median, 6 years; 62%, younger than 10 years; 77%, younger than 20 years; and only 10 patients were older than 40 years). Thirty-nine GCF cases with evaluable epidermis were observed to be protuberant, one with superficial ulceration. Most cases were dermal and subcutaneous, 3 purely dermal, and 5 involved superficial skeletal muscle. Almost all cases demonstrated a honeycomb pattern, and several, a parallel pattern of infiltration. Several cases spared adnexa. Pure GCF areas ranged from solid and collagenized to angiectoid and myxoid, the latter with small to large cystlike spaces. Most cases were relatively hypocellular, except one case with more atypia and mitotic activity. GCF demonstrated myoid whorls in 2 cases, a feature previously described in DFSP. Most remarkable is the peculiar perivascular lymphocytes in an onionskin pattern in GCF, not observed in DFSP. Furthermore, histologic intralesional hemorrhage seems to be common in GCF, particularly near the fascia. Fourteen of our 86 cases demonstrated 5% to 70% (median, 20%) dense nongiant cell storiform areas, interpreted as hybrid GCF-DFSP. Three of these cases demonstrated hypercellular DFSP. One hybrid case had fibrosarcomatous transformation. Two cases of pure GCF recurred as a hybrid tumor with DFSP areas, one of these with hypercellular DFSP. In all but one case, the DFSP was adjacent to GCF with an abrupt transition. Most cases studied were positive for CD34 (more intense in DFSP than relatively hypocellular GCF areas) and negative for smooth muscle actin, desmin, HMB-45, keratin, and S100 protein. GCF is exactly clinically and morphologically the same as Dr Enzinger and colleagues originally described it. Additional observations of marked perivascular and onionskin-like chronic inflammation and consistent hemorrhage may aid in the diagnosis of this previously well-described tumor. Collectively, we now have even more convincing morphologic, immunophenotypic, and molecular evidence that GCF is on a spectrum with DFSP.

Abstract
Tenosynovial giant cell tumours are of two types, localised and diffuse. The diffuse type is also known as pigmented villonodular synovitis (PVNS). There have been 42 previously reported cases of PVNS in the axial skeleton, seven of which were reported in the thoracic spine. A young patient found to have thoracic PVNS and who presented with progressive lower limb weakness and parasthesiae over 3 weeks is reported. Computed tomography and magnetic resonance imaging demonstrated a posterior lesion at T6/7 with local bone invasion. The patient underwent complete resection of the tumour and has had an unremarkable postoperative convalescence with resolution of his signs and symptoms. Total surgical resection is the treatment of choice for this condition and close postoperative follow-up with serial imaging is important to monitor for local recurrence.

Abstract
Osteoclast-like giant cell tumors (OGCT) are rare abdominal tumors, which mainly occur in the pancreas. The neoplasms are composed of two distinct cell populations and frequently show an inhomogenous appearance with cystic structures. However, due to the rarity of these tumors, only very limited clinical data are available. Imaging features and sonographic appearance have hardly been characterized. Here we report on two cases of osteoclast-like giant cell tumors, one located within the pancreas, the other within the liver, in which OGCTs are extremely rare. Both patients were investigated by contrast sonography, which demonstrated a complex, partly cystic and strongly vascularized tumor within the head of the pancreas in the first patient and a large, hypervascularized neoplasm with calcifications within the liver in the second patient. The liver OGCT responded well to a combination of carboplatin, etoposide and paclitaxel. With a combination of surgical resection, radiofrequency ablation and chemotherapy, the patient’s survival is currently more than 15 mo, making him the longest survivor with an OGCT of the liver to date.

Abstract
We present a case of atypical giant cell tumor of the tendon sheath originating from the extensor hallucis longus tendon. The tumor contained multiple nodules and overlay the tendon 16 cm. Magnetic resonance imaging was the most useful preoperative investigation and showed the characteristic appearance of giant cell tumor of the tendon sheath, thus allowing local excision to be planned and executed. We discuss how local recurrence of this tumor could be prevented.

Abstract
A primary giant cell tumor (GCT) originating from the sternum is extremely rare. We report a case of a GCT originating from the sternum in a 45-year-old man who was referred to us for a mass in the anterior chest wall that had been growing slowly. Computed tomography revealed a soft tissue mass involving a large osteolytic and destructive lesion of the sternum body. Subtotal sternectomy and reconstruction with methylmethacrylate were performed. The tumor was 8.5 x 4.5 x 2.5cm, and the histopathological examination confirmed GCT. Radical wide resection of primary sternum tumors and reconstruction with an appropriately rigid prosthetic material are necessary to minimize local recurrence.

Abstract
Solitary orbital fibrous tumor was diagnosed in a 12-year old boy admitted to hospital for right-sided exophthalmos. MRI revealed orbital mass and surgical resection was performed. Histologically the tumor was composed of round or spindle cells with a lot of multinucleate giant cells and pseudovascular spaces. The neoplasm was regarded as a mixoid type of a solitary giant cell-rich fibrous tumor. Immunohistochemical analysis revealed coexpression of CD34, CD99, bcl-2, and CD99 (mic-2). The most important clinical, morphological, and immunohistochemical manifestations are presented in the paper. Major criteria for the differential diagnosis of solitary orbital fibrous tumor and the similar soft tissue tumors are discussed.

Abstract
Soft tissue giant cell tumor of low malignant potential is a rare tumor located in superficial and deep soft tissue. Tumors with osteoclast-like giant cells have been reported in various sites as breast, salivary glands, lung, kidney and pancreas. These tumors are composed of evenly spaced multinucleated giant cells in a background of mononuclear component composed of round, oval or spindled cells. No atypia or significant mitotic activity is encountered. Immunohistochemical stains for TRAP, smooth muscle actin, desmin and cytokeratins are of great value for diagnosis. Nasal cavity represents a very unusual location for this type of tumors; soft tissue tumors must be included in the differential diagnosis of nasal obstruction. Due to the possibility of local recurrence, clinical follow-up is recommended.

Abstract
We report two cases of giant-cell tumour of soft tissue (TCG-TM). The first case occurred in a 26-year-old woman presenting with a subcutaneous tumour of the left leg. Pathological study revealed a tumour comparable to benign giant cell tumour of bone. The patient is well without recurrence 10 months after the diagnosis. The second case concerned a 49-year-old man with a huge mass of the thigh. Microscopically, the tumour was composed of sheets of mononuclear and multinucleated cells. Mononuclear cells presented severe atypia and a high mitotic activity. Eighteen months later, the patient died with diffuse pulmonary metastases. TCG-TMs are uncommon and represent a distinct entity whose clinical behaviour and histological features are similar to giant-cell tumour of bone. The malignant variant is debatable. The differential diagnosis includes other tumours rich in osteoclast-like cells.

Abstract
A case of diffuse-type tenosynovial giant cell tumor arising in the left upper extremity is reported in a 23-year-old man with neurofibromatosis type 1 (NF1)-Noonan syndrome. The predominately mononuclear cellular proliferation with psammomatous calcifications had the immunohistochemical and ultrastructural features of a fibrohistiocytic neoplasm. This uncommon type of soft tissue neoplasm occurring in this unique clinical setting served to open an inquiry into the subject of non-neurogenic tumors in association with NF1 and Noonan syndrome, both manifested in our patient. Nonossifying fibroma of bone as a presumptive fibrohistiocytic tumor is an uncommon but well-documented manifestation in NF1, whereas in Noonan-like syndrome, both giant cell granuloma and pigmented villonodular synovitis are recognized as associated lesions with histologic and immunophenotypic similarities with the diffuse-type tenosynovial giant cell tumor.

Abstract
The purpose of this study was to explain radiographic features of giant cell tumors of the tendon sheath (GCTTS), in particular, osseous extension, by correlating imaging findings with histology in order to increase the accuracy of radiological diagnosis. In a series of 200 consecutive osseous (pseudo) tumors of the hand, on radiography, six patients presented with an intrinsic osseous lesion caused by a histologically confirmed neighboring GCTTS. Available radiographs, computed tomography (CT), and contrast-enhanced magnetic resonance (MR) images were correlated with histology. Radiography showed osseous lesions consisting of well-defined cortical defects in four (one of whom also demonstrated cortical scalloping) and a slightly expansile, well-defined osteolytic lesion in two patients. MR obtained in four patients showed the extraosseous tumor invading/eroding bone and causing cortical scalloping (three and one patients, respectively). Extension depicted on MR was confirmed on the two available resection specimens. All lesions were polylobular (cauliflower or mushroom like) and neighboring tendon sheaths. Dense collagen and hemosiderin-loaded macrophages explained the high CT attenuation and the low MR signal intensity on T2-weighted images that was observed in all four MR and in all two CT scans. The high density of proliferative capillaries explained the marked enhancement observed in all four patients with gadolinium (Gd)-chelate-enhanced MR imaging. GCTTS is a soft tissue (pseudo) tumor that may invade bone and as a consequence mimick an intrinsic osseous lesion on radiographs. In such cases, specific MR and CT features that can be explained by histological findings can be used to suggest the correct diagnosis.

Abstract
Giant cell tumor of the skin is a rare entity showing gross and histological features similar to those of giant cell tumor of the bone. We report a case of malignant giant cell tumor of the thigh in a 55-year-old man. Histological features showed a biphasic population of mononuclear cells admixed with osteoclast-like giant cells. The nuclei of the giant cells were similar to those of the mononuclear cells. This tumor should be distinguished from a variety of cutaneous neoplasms that contain multinucleated giant cells.

Abstract
We report four previously undescribed primary giant cell tumors of the extrahepatic biliary tree and morphologically compare them with 10 anaplastic spindle and giant cell carcinomas with osteoclast-like giant cells of the gallbladder. Two giant cell tumors were located in the distal common bile duct; one in the cystic duct and one in the gallbladder. The 3 patients with bile duct tumors were male, and the only patient with a gallbladder tumor was a female. The age of the patients ranged from 45 to 60 years with an average of 55 years. The patients with bile duct tumors presented with biliary obstruction, and the patient with a gallbladder tumor presented with symptoms of cholelithiasis and a gallbladder mass. Histologically, the tumors were similar to giant cell tumors of bone. They consisted of a mixture of mononuclear and multinucleated osteoclast-like giant cells. The mononuclear cells showed no atypical features, and their nuclei were similar to those of the multinucleated giant cells. CD163 immunoreactivity was restricted to the mononuclear cells, whereas CD68 and HAM 56 labeled only the multinucleated osteoclast-like giant cells. The mononuclear cells were EMA-positive but did not express cytokeratins. Follow-up showed that 3 patients were alive and disease-free 3.7 to 7 years after surgery. The anaplastic spindle and giant cell carcinomas contained a fewer number of osteoclast-like giant cells, and their mononuclear cells showed considerable variation in size and shape, marked cytologic atypia, and numerous mitotic figures. They were focally cytokeratin positive (AE1/AE3; CAM 5.2) and did not label with CD163, CD68, and HAM 56. The benign osteoclast-like giant cells showed immunoreactivity for CD68 and HAM 56 but were negative for CD163 and cytokeratins. Giant cell tumors of the extrahepatic biliary tree are benign true histiocytic neoplasms that should be distinguished from the highly lethal anaplastic spindle and giant cell carcinomas with osteoclast-like giant cells by detailed cytologic analysis and immunohistochemical stains for CD163, CD68, HAM 56, and cytokeratins.
