Abstract
Giant cell tumor is a highly aggressive tumor characterized by a marked proliferation of pleomorphic, bizarre giant cells usually observed in the lungs. The importance of histopathological imaging and the clinical course of this tumor are unknown. The objective of our report was to investigate whether these components affect treatment outcomes and prognosis compared to conventional cancers. A 40-year-old woman with cervical cancer showed leukocytosis and elevated granulocyte colony simulating factor (G-CSF). The patient underwent a radical abdominal hysterectomy. Pathology revealed a poorly differentiated squamous cell carcinoma of the cervix, similar to giant cell carcinoma. The patient recovered from the disease and is alive 37 months after concurrent chemoradiotherapy (CCRT). Leukocytosis and G-CSF were normalized after treatment. This was our second case of giant cell carcinoma of the cervix. Cumulative data on giant cell carcinoma are limited, thus we considered the prognostic significance of the presence of giant cell carcinoma in uterine carcinoma.

Abstract
Giant cell carcinoma of the lung is a rare tumor with poor prognosis. A 70-year-old male was referred to our hospital because of chest pain and abnormal shadow on the chest X-ray. He had a lung tumor invading the chest wall. The tumor was surgically removed, and since the diagnosis of giant cell carcinoma with p-N2 was obtained pathologically, adjuvant chemotherapy was performed. However, the local recurrence was found at eight months after surgery and was treated with radiotherapy( total 70 Gy/28 Fr). The patient has been well for over 10 years with no clinically evident recurrence after treatment.

Abstract
Poorly differentiated thyroid carcinoma (PDTC) refers to a malignant tumour that displays an intermediate prognosis between well-differentiated carcinomas and anaplastic thyroid carcinomas (ATC). In the thyroid, pleomorphic giant cells are observed in ATC or in some non-neoplastic thyroid diseases. We described the case of a 43-year-old woman with a 34-mm nodule in her thyroid right lobe. Microscopic examination revealed an encapsulated tumour with a main solid growth pattern and extensive capsular invasion. Multiple images of angioinvasion were observed. There was neither necrosis nor inflammation. Most of the tumour cells were medium-sized and intermingled with pleomorphic giant tumour cells with bizarre features. The immunoprofile (keratins +, TTF1+, Pax 8+) proved their thyroid origin. By NGS, no molecular alteration was identified. The patient was treated by surgery and radioiodine therapy and she has no recurrence after a follow-up of 24 months. Our case meets all the histological criteria of the Turin proposal for PDTC but with pleomorphic giant cells and is very different from ATC according to clinical, histological and immunohistochemical features. Pleomorphic tumour giant cells in thyroid carcinomas could be present in PDTC and do not always represent dedifferentiation and more aggressive carcinoma, thyroid neoplasm.

Abstract
Osteoclast-like giant cell-type (OCGC) anaplastic carcinoma is a rare variant of pancreatic ductal adenocarcinoma, and its imaging characteristics and progression pattern have not been fully clarified. The patient was a 73-year-old man who had been incidentally found to have a pancreatic head tumor. Computed tomography demonstrated a 3-cm marginally enhanced mass at the pancreatic head, continuing toward the duodenum. Diffusion-weighted magnetic resonance imaging showed a retained diffusion capacity. Duodenoscopy revealed a 1.5-cm polypoid lesion, covered by a dirty coat, near the major papilla. Surgical material revealed OCGC pancreatic anaplastic carcinoma protruding to the duodenum, accompanied by multiple hemorrhagic foci and hemosiderin precipitations.

Abstract
INTRODUCTION Pulmonary sarcomatoid carcinomas (PSCs) are rare tumors within the sarcomatoid carcinoma group. Giant cell carcinoma of the lung (GCCL) is a rare type of PSCs that consists entirely of highly pleomorphic tumor giant cells; the prognosis is poor. PATIENT CONCERNS A patient presented with a single cyst and was diagnosed with GCCL. The patient was a 59-year-old male who was admitted to the hospital with a cough. A chest computerized tomography (CT) scan showed a single, thin-walled cyst containing air in the left upper lobe of the lung. Bronchoscopy revealed chronic bronchitis. The initial diagnosis was pulmonary infection and the patient was treated with antibiotics. The cyst wall increased in thickness, and the cyst eventually formed a cavity. DIAGNOSIS Surgery was performed, and a diagnosis of GCCL was established. The stage was pT1bN1M0 (equal to stage IIB). INTERVENTIONS The patient underwent video-assisted thoracoscopic surgery and 4 cycles of adjuvant chemotherapy consisting of cisplatin and docetaxel. After 9 months, the patient occurred mediastinal lymph node metastasis, and received radiotherapy (60Gy/30F). OUTCOMES His prognosis was good without progression (complete response) based on serial CT scans over 9 months of follow-up evaluations, then the patient occurred mediastinal lymph node metastasis. The patient lived during 30 months of follow-up, after which he was lost to follow-up. CONCLUSION A solitary pulmonary parenchymal cystic lesion usually suggests an infectious disease or congenital abnormality; however, a cystic lesion is occasionally encountered in GCCL.

Abstract
Missing in metastasis B (MIM-B) has been widely reported to inhibit cancer cell invasion and proliferation in a variety of human cancers. However, the functions of MIM-B in lung cancers are still controversial. In addition, the mechanisms and regulation of MIM-B are poorly understood. In the present study, we found that the invasion level of 95C human lung giant-cell carcinoma cells was elevated when MIM-B was knocked down, while the invasion of 95D was suppressed when MIM-B was overexpressed, proving that MIM-B suppresses human lung giant-cell carcinoma cell invasion, which is similar to its function in most cancers. Furthermore, we reported that an increase in DNA methylation density in the promoter of MIM-B by DNA methyltransferase 1 (DNMT1) is correlated with the silencing of MIM-B expression and the high metastasis of 95D human lung giant-cell carcinoma cell line. Taken together, MIM-B, which is regulated by DNMT1 through DNA methylation, is a putative cancer suppressor in human lung giant-cell carcinoma.

Abstract
Primary lung tumor tissue exhibiting numerous multinucleated osteoclast-like giant cells (OGCs) is an extremely rare histological type. In this study, we describe the case of an 82-year-old woman. Chest CT demonstrated an extensive crazy-paving appearance in both of the lung fields and a solid round mass in the right lower lobe. A pathological examination of the tumor revealed sarcomatoid carcinoma containing OGCs combined with diffused, invasive lepidic predominant adenocarcinoma. We herein present an extremely rare lung cancer, invasive lepidic predominant adenocarcinoma extensively involving the lung with areas of sarcomatoid carcinoma containing OGCs.

Abstract
In pleomorphic, spindle cell, and giant cell carcinoma (PSCGC) of the lung, we wondered if an integrated diagnosis including morphological and immunohistochemical features could be related to molecular status. We performed immunohistochemistry on 35 PSCGCs against TTF1, napsin A, p40, ALK, ROS1, and c-MET. Mutational status regarding EGFR, KRAS, BRAF, HER2, and PIK3CA genes was established. Of 18 PSCGCs with adenocarcinomatous or "undifferentiated" carcinoma differentiation, 8 were mutated for EGFR (n = 1), KRAS (n = 2), BRAF (n = 1), HER2 (n = 3), and PIK3CA (n = 1). No PSCGC (0/4) with only squamous cell or adenosquamous (0/2) differentiation was mutated. c-MET overexpression was only seen in PSCGC with adenocarcinomatous or undifferentiated component (n = 5) without squamous cell component. ROS1 and ALK were negative. The presence of a "targetable mutation" was correlated to the presence of morphological or immunohistochemical adenocarcinomatous differentiation (P = .0137). Integrated diagnosis of an adenocarcinomatous component in PSCGC could be associated with the presence of targetable gene mutation. Because only PSCGC with adenocarcinomatous or undifferentiated carcinoma harbors mutations, whereas PSCGC with only squamous or adenosquamous differentiation does not in our study, this might represent a prescreening for patients with PSCGC to be tested for molecular targets. Our results emphasize that careful morphological examination and the use of immunohistochemistry might be useful for the selection of PSCGC tested for a mutational target.

Abstract
Undifferentiated carcinoma with osteoclast-like giant cells of the pancreas (UCOGCP) is an unusual pancreatic neoplasm that represents < 1% of all pancreatic malignancies. Moreover, the giant cells of UCOGCP morphologically resemble the benign giant cells of bone tumors. Due to the rarity of this tumor type, the histogenesis and biologic behavior of UCOGCP remain controversial. Here, we report a case of UCOGCP that exhibited an invasive growth pattern involving infiltration of the adjacent bowel loop and portal vein, as well as superior mesenteric vein thrombosis. The patient underwent a distal pancreatectomy with splenectomy and partial colectomy, followed by four cycles of gemcitabine chemotherapy. No evidence of recurrence was detected after ten years. In addition to this case, clinical information on other UCOGCP cases reported in the English literature is summarized.

Abstract
Mammary carcinoma with osteoclast-like giant cells is rare, and comprises less that 2% of breast carcinoma cases. Herein, we present a case of a 45-year-old woman who underwent breast lumpectomy and sentinel lymph node biopsy for a solitary well defined breast tumor. Histological examination revealed an invasive tumor composed of ducts, small nests and cribriform formations intermixed with a prominent osteoclast like giant cell component. The background stroma is hemorrhagic with conspicuous hemosiderin deposition. The paper will outline the clinico-pathologic characteristic features of this uncommon subtype as well as the current understanding on the pathogenesis of the osteoclast-like giant cells. The invasive carcinoma and the osteoclast-like giant cells staining patterns using immunohistochemical stains for estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2, receptor activator of nuclear-kB, RANK ligand, and matrix metalloproteinase 1 are reported.

Abstract
OBJECTIVE To explore the clinicopathological features and prognostic factors of three rare and poor-prognostic pathological subtypes of primary liver carcinoma, and improve the clinical diagnosis and surgical treatment. METHODS A retrospective analysis of clinicopathological data of 69 patients with rare pathological subtypes of primary liver carcinoma, diagnosed by postoperative pathology in our hospital from October 1998 to June 2013 was carried out. The data of 80 cases of common poorly differentiated hepatocellular carcinoma treated in the same period were collected as control group. Kaplan-Meier method was used to analyze the survival rate, and Cox proportional hazards model was used for prognostic analysis in the patients. RESULTS Thirty-four cases were combined hepatocellular carcinoma and cholangiocarcinoma (CCC, 28 males, 6 females), with a median age of 52 years (range, 33 to 73). Ninteen cases were giant cell carcinoma (GCC, 16 males and 3 females), with a median age of 59 years (range, 38 to 66). Sixteen cases were sarcomatoid carcinoma (SC, 14 males and 2 females), with a median age of 57 years (range, 46 to 70). The survival analysis revealed that median survival time and the 1-, 3-, 5-year survival rates for these 3 groups were 20 months, 61.8%, 29.4%, and 20.6% in the CCC patients, 13 months, 52.6%, 31.6%, and 0% in the GCC patients, and 8 months, 31.3%, 0%, 0% in the SC patients, respectively. The median survival time and survival rate of the SC group were significantly lower than those of the other three groups (P < 0.05). However, in the SC group, the incidences of hilar lymph nodes metastasis, vascular tumor emboli and invasion of adjacent organs were significantly higher than those in the other three groups (P < 0.05). There were no statistically significant differences among the other three groups (P > 0.05). The levels of carcino-embryonic antigen were higher in the three rare subtype groups than that of the control group. The incidences of multiple tumors of the three rare subtype groups were higher than that of the control group (P < 0.05). Positive surgical margin was an independent unfavorable prognostic factor. CONCLUSIONS The combined hepatocellular carcinoma and cholangiocarcinoma, giant cell carcinoma and sarcomatoid carcinoma have a poor prognosis. Among them sarcomatoid carcinoma is the most malignant and poor prognostic one. Radical resection is recommended.

Abstract
We herein report a case of anaplastic carcinoma of the pancreas with remarkable intraductal tumor growth into the main pancreatic duct. A 76-year-old male was referred to our hospital for treatment of a pancreatic tumor. Preoperative examinations revealed a poorly defined tumor in the main pancreatic duct in the body of the pancreas, accompanied with severe dilatation of the main pancreatic duct, which was diagnosed as an intraductal papillary-mucinous neoplasm. We performed distal pancreatectomy and splenectomy. The pathological examination revealed that the tumor consisted of a mixture of anaplastic carcinoma (giant cell type) and adenocarcinoma in the pancreas. There was a papillary projecting tumor composed of anaplastic carcinoma in the dilated main pancreatic duct. The patient is now receiving chemotherapy because liver metastasis was detected 12 mo after surgery. In this case, we could observe a remarkable intraductal tumor growth into the main pancreatic duct. We also discuss the pathogenesis and characteristics of this rare tumor with specific tumor growth.

Abstract
OBJECTIVE To establish cytological features of pulmonary pleomorphic carcinoma (PC) or giant cell carcinoma (GC), we evaluated the cytological characteristics of these tumors using a multidisciplinary approach. STUDY DESIGN Samples from 13 surgically resected and histologically confirmed PC or GC patients were collected from our institutes. Eight cases without prior chemotherapy before surgery were selected, and cytological features were analyzed. RESULTS The background contained numerous lymphocytes and neutrophils. The tumor cells were arranged in flat loose clusters, but some were in fascicles. The shape of the tumor cell was spindle or pleomorphic, and the sizes of the tumor cells varied by more than 5-fold. The tumor cells had an abundant, thick and well-demarcated cytoplasm. The location of the nucleus was centrifugal, and the nucleus was oval or irregularly shaped. Multinucleated giant cells were frequently observed. The size of the nucleus was more than 5 times that of normal lymphocytes, and its size also varied by more than 5-fold. The nuclear membrane was thin, and nuclear chromatin was coarsely granular, while the nucleolus was single and round. CONCLUSION PC or GC has characteristic cytological features, however, spindle cells tended to be hardly observed in cytological specimens in some cases.

Abstract
Initially described 40 years ago (Rosai), the undifferentiated osteoclastic-type giant cell carcinoma (IOGCC) is a variant of ductal adenocarcinoma and accounts for less than 1% of exocrine pancreatic tumors. Its extreme rarity, with consequent existence of few reports and clinical experience, leads to the arousal of doubts with regard to its histogenesis, types of approach and therapeutical attitudes. It is important to note that in Portugal no similar case is registered in medical literature. A 61 year old patient admitted to the Internal Medicine Ward 3 at Coimbra University Hospital presents with a voluminous intra-abdominal mass in the left hypochondrium and microcytic anemia. During the investigation, a pancreatic neoplasm was identified, and the patient was submitted to surgical resection, the anatomo-pathological study of the tumor having revealed IOGCC. The particularities of the case, current available therapeutical options and its evolution are discussed, as well as a revision of the existing literature.

Abstract
Less than 1% of basal cell carcinomas are giant basal cell carcinomas. Giant basal cell carcinomas are rare. They preferentially involve the trunk and are commonly associated with neglect. Giant basal cell carcinomas of 10 cm or greater are associated with a high rate of metastasis. We report a case of giant basal cell carcinoma of the leg which is not associated with neglect and no signs of metastasis, despite being more than 10 cm in diameter. The present paper includes a brief review of the literature.

Abstract
OBJECTIVES To investigate molecular mechanisms of PAR-1 regulation on intracellular Ca²(+) mobilization in lung giant cell carcinoma cells in vitro and its involvement in tumor metastasis. METHODS Free intracellular Ca²(+) ([Ca²(+)]i) was measured in lung giant cell carcinoma PLA801C and PLA801D cells by confocal microscopy. Sense and anti-sense PAR-1 expression vectors were transfected into PLA801C (C+)and PLA801D(D-) cells, respectively. The effects of PAR-1 expression were investigated by thrombin and TRAP-induced mobilization of [Ca²(+)]i in the C+ and D-cells. RESULTS There were significant differences of the mean values of [Ca²(+)]i between PLA801D (59.55) and PLA801C cells (35.46, P < 0.01). The mean [Ca²(+)]i of C+ cells (45.77) was significantly higher than that of its control CV cells (35.46, P < 0.05), and the mean [Ca²(+)]i of D-cells (48.42) was significantly lower than that of its control DV cells (59.55, P < 0.05). The peaks of [Ca²(+)]i of C+ and CV cells were 48.19 ± 9.84 and 45.64 ± 9.87 (P < 0.05) respectively at 80 s and 100 s after thrombin treatment, but were 111.31 ± 25.00 and 52.93 ± 11.21 (P < 0.05) respectively at 60 s after TRAP treatment. The peaks of [Ca²(+)]i of D- and DV cells were 40.71 ± 5.89 and 61.07 ± 21.36 (P < 0.05) respectively at 60 s after thrombin treatment, but were 84.98 ± 11.23 and 102.58 ± 21.48 (P < 0.05) respectively at 40 s after TRAP treatment. CONCLUSIONS The high metastatic potential of PLA801D and PLA801C may be related to [Ca²(+)]i of the tumor cells. PAR-1 may play an important role in the metastasis of lung giant cell carcinoma cells by up-regulating the intracellular Ca²(+).

Abstract
Giant cell tumor (GCT) of bone arising from a phalanx of a finger is extremely rare. We report two cases of GCT arising from a phalanx of a finger. One case presented with recurrence following the amputation of the left ring finger (performed elsewhere). He was treated successfully with ray amputation. The other case was treated primarily by intralesional curettage and autogenous bone graft. At their most recent follow-ups (80 and 24 months, respectively), both were recurrence free and had returned to their previous occupational and recreational activities.

Polyaxial screws for lumbo-iliac fixation after sacral tumor resection: experience with a new technique for an old surgical problem. Int J Surg 2009; 7:529-33. [PMID: 19735745 DOI: 10.1016/j.ijsu.2009.08.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2009] [Revised: 07/18/2009] [Accepted: 08/22/2009] [Indexed: 11/20/2022]
Abstract
BACKGROUND Although numerous reports have been published about various methods for reconstruction after sacrectomies, there are still biomechanical and technical dilemmas that are unaddressed. This report describes the experience at authors' institution of five cases in which polyaxial pedicle screws construct has been successfully used for lumbo-iliac fixation after sacral tumor resection. METHODS Five cases of sacral tumors, two of Ewing's sarcoma and three of giant cell tumor (GCT) underwent surgical resection and then reconstruction was done with hardware using vertical rods placed alongside the spine bilaterally, transfixing monoaxial and polyaxial pedicle screws in lower lumbar levels and polyaxial screws into the ilium bilaterally. Cross links were also used to connect the two vertical members, thus enhancing biomechanical stability of the construct. Use of autologous bone grafts was relied upon to fill the gap created by sacral resection. RESULTS No instrumentation failure was noted and the continuity of the spine and pelvis was well established with the instrumentation and auto grafts. In follow up of these patients (1-3 years), no complications were seen. CONCLUSION Polyaxial pedicle screws fixation is an effective technique to transmit axial load from spine to the appendicular bone and can be used safely in patients in whom sacral integrity is compromised after surgical resection. However, the long term benefits of this technique need to be evaluated.

Abstract
Extraskeletal osteoclast-like giant cell (OGC) tumors are uncommon and have mainly been found in the breast and pancreas. OGC neoplasms of the urinary tract are extremely rare, and their histogenesis and biologic behavior remain controversial. Gross hematuria is the most common presenting symptom, as in transitional cell carcinoma. The prognosis is poor in patients with extraskeletal OGC tumors. Here, we present the case of a 62-year-old man who received transurethral bladder tumor resection due to painless gross hematuria. Pathology showed OGC carcinoma. Abdominal computed tomography showed tumor invasion over the right lateral wall of the bladder and distal third of the ureter. The patient received radical cystectomy and partial distal ureterectomy with transureteroureterostomy. No local tumor recurrence or distant metastasis was found at the 5-month follow-up.

Abstract
The paper describes a case of maldiagnosis of giant-cell tumor in a patient with parathyroid osteodystrophy, in this connection elbow joint resection and replacement were made. Parathyroid adenoma with the symptoms of primary hyperparathyroidism was diagnosed only two years after surgery. Progression of diseases was accompanied by severe bone changes and the development of urolithiasis complicated by chronic renal failure. Thus, the interpretation of bone tissue changes without considering clinical and laboratory data led to the unwarranted surgical intervention and the late diagnosis of primary hyperparathyroidism. Differential diagnosis of a giant-cell tumor should be made, by obligatorily considering clinical and laboratory data, including the parameters of calcium metabolism.

Abstract
Gynaecomastia, or enlargement of the male breast may result from various endocrine dysfunctions and often reflects ectopic production of substances such as hCG and estradiol. We report on the case of a 30 year old man who presented with gynaecomastia and elevated plasma levels of hCG, estradiol and testosterone. As a result of several diagnostic procedures such as selective venous sampling and magnetic resonance tomography (MRT), a hCG producing tumor of the upper lobe of the left lung was found. This hormonal overproduction induced an enhanced secretion of estradiol and testosterone in the testicular tissue. Histology revealed a giant cell carcinoma with positive immunostaining for hCG. This case report further underlines the necessity of an intensive search for ectopic beta-hCG production due to malignant tumours, in particular in the adult.

Abstract
A 58-year-old man who complained of an abdominal tumor was admitted to our hospital. Abdominal CT scan showed that a 15-cm tumor occupied the entire right upper abdomen and that there were ascites and liver metastases. A liver biopsy was performed. The liver biopsy showed a small cell carcinoma pattern, but no definitive origin of the tumor was determined. Considering the extensive peritoneal invasion and multiple liver metastases, he received 2 / courses of cisplatin/etoposide chemotherapy, but his tumor became larger with concomitant abdominal pain and nausea. The patient suddenly died due to multiple organ failure caused by tumor necrosis. The autopsy revealed a pathological diagnosis of primary small cell carcinoma of the pancreas.

Abstract
We report a case of urinary bladder cancer that produced granulocyte-colony stimulating factor (G-CSF). A 56-year-old man was admitted to our hospital with the chief complaint of macroscopic hematuria. Cystoscopy demonstrated a thumb tip-sized bladder tumor. Computerized tomography and magnetic resonance imaging showed muscular invasion in the bladder, but no distant metastases. The complete blood count and laboratory examination showed leukocytosis of 25,200/mm3 and a high G-CSF level of 145 pg/ml in the peripheral blood. Although he underwent total cystectomy and adjuvant chemotherapy using methotrexate, vinblastine, doxorubicin and cis-platinum (M-VAC) under the diagnosis of locally advanced bladder cancer, he died of progressive disease of the carcinoma about eight months after the diagnosis. A temporary decrease of white blood cell count and serum GCSF were observed just after treatment. The histopathological diagnosis was undifferentiated giant and spindle cell carcinoma of the urinary bladder (grade 3, pT3b, pN1). The tumor cells exhibited positive staining for G-CSF immunohistochemically.

Abstract
Giant-cell containing neoplasms of the pancreas are rare with few reports documenting their cytologic appearance. Giant-cell containing neoplasms of the pancreas have been divided into two subtypes corresponding to the osteoclastic giant-cell tumor of the pancreas and the pleomorphic giant-cell carcinoma of the pancreas. Despite the better prognosis reported in some series for osteoclastic giant-cell tumors, the most recent edition of the World Health Organization classification lumps the two entities into a single category designated as undifferentiated carcinoma with osteoclast-like giant cells. Smears obtained from osteoclastic giant-cell tumors show numerous giant-cells with clustered overlapping, bland appearing nuclei containing prominent nucleoli consistent with an osteoclast-type multinucleated giant-cell. These neoplasms contain a second population of mononuclear cells showing more marked nuclear atypia. Pleomorphic giant-cell carcinomas are characterized by anaplastic giant-cells displaying marked nuclear pleomorphism. The mononuclear component is also pleomorphic with markedly atypical epithelioid and spindle shaped cells. In three reported cases, a tumor contained a mixture of the two cell patterns. Thus, undifferentiated carcinoma with osteoclast-like giant cells and pleomorphic giant cell carcinoma may represent a morphologic spectrum with pure osteoclast-like giant-cell tumors at one end and pleomorphic giant-cell carcinoma at the other. Fine-needle aspiration specimens from pure osteoclast-like giant-cell tumors will contain a population of bland multinucleated osteoclastic-like giant-cells that differ markedly from the anaplastic giant-cells of pleomorphic giant-cell carcinoma. The difference in the appearance of the giant-cells aids in distinction of the two neoplasms. When in pure form, the two neoplasms may follow different clinical courses.

Abstract
Giant cell carcinoma of the lung is a specific type of lung carcinoma characteristically associated with a highly aggressive clinical behavior. This tumor comprises approximately 1-5% of all lung cancers, affecting a similar patient population as other primary pulmonary carcinomas. It is not routinely treated surgically, owing to the fact that it is metastatic at the time of diagnosis. The cytological diagnosis of this entity on aspiration biopsy has an appreciable impact on patient care. We retrospectively examined 15 cases of lung fine-needle aspirates in which a diagnosis of giant cell carcinoma or large cell carcinoma with giant cell features was made. We applied the criteria for cytological diagnosis of giant cell carcinoma previously set forth in the literature. In cases where there is a tissue diagnosis, we compared the results with the corresponding fine-needle aspirates and correlated them with patient survival. Conclusions are made regarding the reliability of the diagnostic criteria of this malignancy.

Overexpression of axin downregulates TCF-4 and inhibits the development of lung cancer. Ann Surg Oncol 2007; 14:3251-9.

Abstract
BACKGROUND T cell factor 4 (TCF-4) mediates a nuclear response to wingless/int (Wnt) signals by interacting with beta-catenin. Axis inhibition protein (axin) is an important negative regulator of the Wnt signaling pathway. Our aims were to examine the relationship between axin and TCF-4 and to explore the effects of axin on the development of lung cancer. METHODS Expression levels of axin and TCF-4 were examined in 107 lung cancer specimens by immunohistochemistry. The axin gene was transfected into lung cancer BE1 cells. The expression levels of axin, beta-catenin, and TCF-4 were detected with immunofluorescence and reverse transcription-polymerase chain reaction (RT-PCR) experiments. Apoptosis, proliferation, and the invasive ability of lung cancer cells were examined using flow cytometry, 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT), and Matrigel invasive assays. RESULTS Preserved axin expression correlated negatively with TCF-4 expression (P = .031). Axin expression differed with respect to degree of differentiation (P = .025) and histological tumor type (P = .031). TCF-4 expression differed relative to tumor, node metastasis (TNM) stage (P = .024). BE1 cells transfected with axin (BE1-axin cells) exhibited a significant decrease in TCF-4 expression. The level of apoptosis in BE1-axin cells was significantly increased, while the proliferative and invasive abilities of BE1-axin cells were decreased. CONCLUSION These results suggest that reduced expression of axin or augmented expression of TCF-4 is associated with the malignant behavior of lung cancers. Overexpression of axin can downregulate expression of TCF-4 and can inhibit the ability of lung cancer cells to proliferate and invade.

Abstract
Basal cell carcinoma is exceedingly common, but tumors >5 cm in size or giant basal cell carcinomas (GBCCs) are rare. We retrospectively review 10 GBCCs in 8 patients treated by aggressive surgical excision and reconstruction in a single operative procedure. With the exception of 1 chest lesion, all GBCCs involved the face or scalp. The 10 large defects were reconstructed with 5 free-tissue transfers, 2 pedicled musculocutaneous flaps, and 3 rotational skin flaps. There has been no evidence of local recurrence or metastasis in a mean follow-up of 29 months. Neglect has a well-established role in the presence of GBCCs, with undiagnosed preexisting medical problems also common. Surgical excision and reconstruction is the treatment of choice and can be readily accomplished in a single procedure with few complications, good oncologic control, and acceptable cosmetic results.

Abstract
We describe the histologic variants of papillary and follicular carcinomas associated with 109 spindle and giant cell carcinomas (SGCC) of the thyroid and determine the incidence of rhabdoid and thyroglobulin inclusions in these tumors. In addition, we searched for rhabdoid and thyroglobulin inclusions in 120 papillary carcinomas (PC) (all 15 variants included), 23 differentiated follicular carcinomas (DFC), (6 with insular pattern), 6 poorly differentiated follicular carcinomas (PDFC) and 34 follicular adenomas (FA). The following differentiated thyroid carcinomas coexisted with SGCC: 51 (46.8%) PC, (34 conventional type, 14 tall cell variant and 3 follicular variant), 6 (5.5%) DFC, 1 follicular carcinoma with insular pattern (0.9%), and 3 oncocytic carcinomas (2.8%). Eleven SGCC (10%) and 2 (33%) PDFC showed rhabdoid features, but lacked thyroglobulin inclusions. Thyroglobulin inclusions were found in 10 FA (29%), 8 (17%) follicular variants of PC and in 7 (30.4%) DFC. There were no rhabdoid inclusions in any of these differentiated thyroid tumors. Our findings support the hypothesis that most SGCC result from dedifferentiation or anaplastic transformation although the mechanisms that underlie this transformation remain unknown. The finding that only 1 (0.9%) SGCC was associated with follicular carcinoma with insular pattern contradicts the opinion that this tumor occupies an intermediate position between differentiated and anaplastic carcinomas. Rhabdoid features are markers of PDFC and SGCC while thyroglobulin inclusions are markers of FA and differentiated thyroid carcinomas with follicular phenotype.

Abstract
OBJECTIVE To study the functional aspects of protease-activated receptor 1 (PAR-1) gene involved in tumor metastasis. METHODS Two human lung giant cell carcinoma cell lines PLA801C (low metastasis potential) and PLA801D (high metastasis potential) were chosen as in-vitro human cancer model systems. Sense and anti-sense expression constructs of PAR-1 gene (pC/PAR1s and pC/PAR1as) were transfected into PLA-801C and PLA-801D cells by lipofection. PAR-1 expression was determined by RT-PCR and western blot analysis. MTT growth, flow cytometry analysis, fibronectin adhesion, and matrigel invasion assays were used to study the effect of PAR-1 expression on the proliferation, adhesion, and invasion of the transfected cells. RESULTS Appropriate up-regulation or down-regulation of protein expression of PAR-1 was observed in both transfected cell lines (PLA801C and PLA801D) to express PAR-1s or PAR-1as, respectively. Expression of the sense PAR-1 markedly increased cellular proliferation, adhesion and invasion of PLA-801C cells. In contrast, anti-sense PAR-1 significantly inhibited cell growth, adhesion and invasion capabilities, along with cell arrest at G0/G1 phase of the PLA-801D cells. CONCLUSIONS Successful up- and down- regulation of expression of PAR-1 can be achieved by in-vitro transfection of sense and antisense PAR-1 constructs. PAR-1 may enhance metastasis of lung cancer through its regulation of cellular proliferation, adhesion and invasion. Down-regulation of expression of PAR-1 may provide a new therapeutic strategy against lung carcinoma.

Abstract
OBJECTIVE This report describes a case of a 62-year-old male with giant cell carcinoma of the larynx that presented as a neck mass and hoarseness. METHODS Case report, review of the world literature, and an immunohistochemical examination. RESULTS Extended total laryngectomy and bilateral functional neck dissection were performed. Microscopical examination showed that the tumor was composed of solid masses of anaplastic small cells with hyperchromatic nuclei. There were multinucleated giant cells with huge nuclei, prominent nucleoli, and clear or eosinophylic cytoplasm. The diagnosis of giant cell carcinoma of the larynx was made. An immunohistochemical staining was applied to the case and tumor showed immunoreactivity with cytokeratin 8/18, cytokeratin 18, cytokeratin 19, vimentin, epithelial membrane antigen, S-100, cytokeratin 7 and did not show immunoreactivity with cytokeratin 10, cytokeratin 20, and carcinoembryogenic antigen. CONCLUSION Giant cell carcinoma of the larynx is an extremely rare tumor the origin of which is not clearly understood. It is believed to be the counterpart of giant cell carcinoma of the lung in larynx. It is the sixth case reported in English literature and also the first case that is examined immunohistochemically. In conclusion, giant cell carcinoma of the larynx is confirmed to be a specific entity of simple epithelial origin and it is the counterpart of giant cell carcinoma of the lung.

Abstract
Hepatocellular carcinoma (HCC) is the second most common primary malignant hepatic tumor in children. It often develops in patients with underlying liver disease. We report the clinicopathologic features of an unusual HCC occurring in an infant who presented with features of Cushing's syndrome due to bilateral adrenal hyperplasia. The tumor is characterized by epithelial syncytial giant cells. Giant cell carcinoma of the liver has been previously reported, but the cells were osteoclast-like (ie, mesenchymal type) and not epithelial type as it is in this patient. We propose to use the term HCC, syncytial giant cell type, to denote this apparently novel lesion.

Abstract
We report on a 61-year-old Japanese male with a pedunculated tumor in the common bile duct. The tumor consisted of two types of neoplastic cells. The majority showed atypical spindle- and giant-shaped features and proliferated densely in an inflammatory stroma, revealing a sarcomatous pattern. They expressed vimentin, KL-1, and CAM5.2. The remaining minority showed glandular and tubular features, occupied only less than 5%, located only in the tumor surface, and expressed wide spectrum keratin, KL-1, CAM5.2, epithelial membrane antigen, AE1/AE3, and carcinoembryonic antigen. CD68-positive osteoclast-like giant cells were also observed. Therefore, the patient was diagnosed as having an undifferentiated carcinoma, spindle and giant cell type.

Abstract
BACKGROUND & OBJECTIVE Lung pleomorphic (spindle/giant cell) carcinoma is a rare epithelial malignant tumor. This study was to investigate its clinicopathologic and prognostic characteristics. METHODS Clinicopathologic records of 17 patients with lung pleomorphic (spindle/giant cell) carcinoma were reviewed and compared with those of the patients with other histopathologic types of lung cancer treated in the same period. All patients underwent surgical resection. Kaplan-Meier method was used for survival analysis. Cox proportional hazards model was used for prognostic analysis. RESULTS The 17 patients consisted of 15 men and 2 women with median age of 58 (45-78)û 5 at stage I, 3 at stage II, and 9 at stage III by pathologic TNM staging. Of the 17 cases of lung pleomorphic (spindle/giant cell) carcinoma, 2 were lung exclusive spindle cell carcinoma, 5 were lung carcinoma with spindle cells (combined with one kind of epithelial components, such as squamous cell carcinoma in 3 cases, adenocarcinoma in 1 case, and large cell carcinoma in 1 case), 10 were lung carcinoma with giant cell carcinoma (combined with one kind of epithelial components in 5 cases, two kinds in another 5 cases). Four patients at stage I survived free of tumor for more than 5 years. The median survival time was significantly shorter in lung pleomorphic (spindle/giant cell) carcinoma patients than in lung squamous cell carcinoma patients (36 months vs. 61 months, P=0.027), and was also significantly longer in patients with carcinoma containing spindle cells (including spindle cell carcinoma) than in patients with carcinoma containing giant cells (64 months vs. 18 months,P=0.026). Lymph node metastasis and carcinoma containing giant cells were poor prognostic factors of lung pleomorphic (spindle/giant cell) carcinoma. CONCLUSION Lung carcinoma containing giant cells has multiple cells components, and has worse prognosis than lung carcinoma containing spindle cells and spindle cells carcinoma do.

Giant cell tumour of talus--a case report. JOURNAL OF THE INDIAN MEDICAL ASSOCIATION 2007; 105:96-8. [PMID: 17822179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 05/17/2023]
Abstract
Giant cell tumour of the talus bone is rare and is usually seen in skeletally mature adults. Here a case of giant cell tumour of the talus in a skeletally immature boy of 15 years is reported. The patient presented with swelling and tenderness of the left ankle with an osteolytic lesion seen in the talus on x-ray. A trephine biopsy followed by left talar excision was done. Following the biopsy report the patient underwent arthotomy and joint clearance. There was no recurrence noted at six months follow-up.

Abstract
Hemorrhage in giant cell adenomas of the pituitary gland was detected in 20.8%. It occurred mostly in supracellular mixed multi-nodular tumors. The course of the disease was symptom-free, acute, subacute or mild. There was a relationship between pituitary apoplexy course, on the one hand, and age and tumor growth, on the other. Since postoperative complication and lethality rates were relatively higher in younger patients, it is suggested that differentiated approach be taken to the diagnosis and management of the disease.

Abstract
We encountered a 59-year-old man with advanced lung cancer with multiple swollen lymph nodes. At autopsy the lung cancer was revealed as giant cell carcinoma. Microscopic examination showed no cancer cells, but there was polyclonal proliferation of plasma cells in the lymph nodes and in the bone marrow. In the kidneys, proliferation of mesangial matrices and mesangial cells was found. This presentation resembled multicentric Castleman's disease (MCD), in which interleukin-6 (IL-6) has a great role. Immunohistochemical staining was positive for IL-6 in cancer cells. This is the first reported case of an IL-6-producing giant cell carcinoma of the lung with MCD-like presentation.

Abstract
BACKGROUND Trousseau's syndrome is a prothrombotic state associated with malignancy that is poorly understood pathophysiologically. METHODS AND RESULTS Here we report studies on the blood of a 55-year-old man with giant-cell lung carcinoma who developed a severe form of Trousseau's syndrome. His clinical course was dominated by an extremely hypercoagulable state. Despite receiving potent antithrombotic therapy, he suffered eleven major arterial and venous thrombotic events over a 5 month period. We examined the patient's blood for tissue factor (TF), the major initiator of coagulation, and found its concentration in his plasma to be forty-one-fold higher than the mean concentration derived from testing of 16 normal individuals. CONCLUSION Almost all of the TF in the patient's plasma was associated with cell-derived microvesicles, likely shed by the cancer cells.

Abstract
BACKGROUND Squamous cell cancer of the human cervix presents within a limited numher of well-defined categories inclusive of a large cell variant. Multinucleated giant cell lesions do not feature in any current classification of malignancy of this type. CASE A case of true multinucleated giant cell carcinoma of squamous cell origin of the cervix is described. Two separate, discontinuous types of giant cells were recognized. Remarkable synchronicity of both cell division-related DNA amplification and apoptosis-related DNA disassembly was found and is illustrated in detail using immunocytochemical demonstration of Ki-67 antigen distribution. CONCLUSION This case of multinucleated giant cell carcinoma of squamous cell origin, in light of observed synchronization of both proliferative and apoptotic nuclear activity, raises fundamental questions with respect to cytoplasmic factors controlling such processes.

Abstract
Extranodal follicular dendritic cell (FDC) tumors are rare. Recognition of the morphological spectrum of FDC tumors is important to clinical diagnosis. Herein is presented a case of pancreatic FDC sarcoma with unusual clinicopathological features. A 64-year-old male patient presented with weight loss, poor appetite, abdominal fullness, mild anemia and mild peripheral eosinophilia. Histologically, the tumor was composed of both epithelioid and spindle cells with abundant intracytoplasmic hyaline globules. These tumor cells were positive for CD21, CD23, CD35, S-100 protein, fascin and clusterin. Both epithelioid and spindle tumor cells independently colonized the liver and formed two tumor nodules 18 months after the initial resection. Notably, the two hepatic metastases additionally acquired patchy expression of human leukocyte antigen-DR. The epithelioid FDC in one of the hepatic lesions transformed into numerous bizarre giant cells, which could easily be confused with a metastatic giant cell carcinoma from the pancreas. FDC tumor should therefore be included in the differential diagnoses when dealing with a giant cell tumor.

Abstract
INTRODUCTION The surgical treatment of Stage III or aggressive giant cell tumour of the bone, whether to perform intralesional or en-bloc resection, remains controversial. The aim of this study is to identify the effectiveness of en-bloc resection for local control and final oncological outcome of the disease. METHODS The data of 20 consecutive patients with Stage III giant cell tumour were retrospectively reviewed to determine the local control and oncological outcome after treatment with wide resection. RESULTS The majority of the patients presented late with mean duration of symptoms of 24 months, and four patients presented with recurrences. All patients were treated with wide resection except for two patients who underwent ablative surgery due to major neurovascular involvement. Ten patients required free vascularised tissue transfer to cover massive soft tissue defect. Local recurrence occurred in one patient who was again treated with wide resection and vascularised flap. Six patients had pulmonary metastases. Two patients with resectable disease were treated with thoracoscopic surgery and they remained disease-free 36 months after surgery. Two patients with multiple lung metastases were treated with chemotherapy and the disease remained non-progressive. The remaining two patients who refused chemotherapy showed radiological progression, and one succumbed to the disease with massive haemoptysis. CONCLUSION Aggressive giant cell tumour of bone should be treated with wide resection for better local control, and treatment of pulmonary metastases is mandatory for overall prognosis.

Abstract
BACKGROUND Primary neoplasms of the sphenoid sinus are a rare occurrence, accounting for approximately 1-2% of all paranasal sinus tumors. Here we report a series of four such patients. METHODS Four patients with sphenoid sinus neoplasms were identified (1%), all treated during the year 2003. RESULTS The four patients included two women and two men (mean age 61 years, range 44-70 years). Two patients presented with unilateral abducens cranial nerve (CN) palsies; one had trigeminal facial numbness and dizziness; another had headache, epistaxis, and partial third and fourth CN palsies. MRIs in all patients demonstrated large sphenoid sinus masses with partial clival and sellar bone erosion but with clear visualization of the pituitary gland above the mass. Cavernous sinus invasion was present in all four cases, including one patient with tumor in the ethmoid sinus and intra-tumoral hemorrhage. No patients had endocrinopathy. All patients underwent subtotal tumor removal via an endonasal transsphenoidal route. Tumor histology included neuroendocrine carcinoma, sinonasal undifferentiated carcinoma, mucoepidermoid carcinoma, and giant cell tumor. Post-operatively, all four patients had improved symptoms with complete resolution of diplopia in 3 of 3 patients. Metastatic work-ups were negative in all patients, and all received fractionated stereotactic radiotherapy; three received chemotherapy. One patient required a second endonasal tumor debulking 15 months after the first for new visual loss that then resolved. At a median follow-up of 21 months, all patients are alive and functional. CONCLUSIONS Intra-sphenoidal tumors are locally invasive tumors that include a wide pathological spectrum. In this small series, they presented with cavernous sinus symptoms and headache but not endocrinopathy. Recognizing their distinctive clinical presentation and MRI features is helpful in differentiating them from primary sellar tumors. Their aggressive nature warrants a multimodality treatment plan including surgical debulking, radiotherapy, and chemotherapy in some cases.

Abstract
BACKGROUND Breast cysts are mainly benign and are reported in association with fibrocystic disease and phyllodes tumor. Rarely have cystic changes been reported to occur in malignant tumors. They are usually small but large in rare cases. Giant breast cysts are very rare, and only a few cases have been reported. CASE A 37-year-old woman presented with a rapidly growing breast mass. Mammography showed a huge, well-circumscribed cystic mass (17 x 16 x 16 cm) suggestive of a benign lesion. Cytologic examination revealed a highly cellular tumor composed of malignant cells of various sizes and shapes in a necrotic background. The smears were diagnosed as positive for malignancy and suggested metaplastic carcinoma. Mastectomy was performed, and histologic study confirmed the cytologic diagnosis. CONCLUSION This is the first reported case of a breast cyst of this size. Clinically the cyst was confused with a benign lesion. The fine needle aspiration aided the diagnosis and planning of treatment.
