Abstract
Follicular dendritic cell sarcoma (FDCS) is unusual, and those with an extranodal origin in the head and neck region are extremely rare. To date, no cases of tumors featuring the characteristics of follicular dendritic cells were reported in Korea. We report a new case of FDCS of the tonsils in a 65-year-old man. A diagnostic tonsillectomy was performed. Based on histopathologic and immunohistochemical findings, the patient was diagnosed with FDCS. Adjuvant radiotherapy was performed due to a high mitotic count. The patient survived with a 2-year disease free period. The differential diagnosis of a tonsillar mass must include FDCS. In cases in which FDCS is suspected on histopathologic examination, an immunohistochemical study is essential for the diagnosis.

Abstract
We report the case of a primary nasopharyngeal interdigitating dendritic cell tumor (IDDCT). A 25-year old male presented with bilateral decreased hearing, double vision, and ataxia. Flexible nasopharyngoscopy reviewed a large mass obstructing and filling the entire nasopharynx. MRI and PET-CT confirmed the presence of the primary tumor and demonstrated bilateral cervical lymphadenopathy. Biopsy of the nasopharynx revealed a hematolymphoid neoplasm with dendritic cell differentiation, most consistent with an IDDCT. The lesion was unresectable. The patient was treated with definitive radiotherapy to 66 Gy to the primary tumor and 50 Gy to the bilateral cervical lymphatics using an IMRT technique. A complete response was achieved and the patient remains disease free at the primary site 23 months after completion of radiotherapy.

Abstract
Interdigitating dendritic cell sarcoma (IDCS) is a rare tumor derived from interdigitating dendritic cells. Three cases of IDCS associated with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) have been described, but no clonal relationship between the 2 neoplasms was demonstrated. We present a detailed case analysis of a CLL/SLL with metachronous IDCS and demonstrate that these 2 neoplasms are clonally related. The IDCS and CLL cells had trisomy 12 and identical monoclonal immunoglobulin heavy chain gene rearrangements. Analysis of transcription factors with a role in myeloid differentiation demonstrated PU.1 up-regulation and C/EBPalpha down-regulation in IDCS compared with CLL. High-density array comparative genomic hybridization also identified gains in part of chromosome 16q in IDCS. Our study demonstrates for the first time clonal transformation of CLL/SLL into IDCS. This phenomenon may be triggered by alterations in lineage-determining transcription programs, which result in transdifferentiation, coupled with additional oncogenic stimuli caused by chromosomal imbalances.

Abstract
Interdigitating dendritic cell sarcoma (IDCS) is an exceedingly rare neoplasm arising from the antigen-presenting cells of the immune system. We report a case of IDCS occurring in a 69-year-old man who presented to an outside institution with a painless mass in his right parotid gland for several months. He presented to our institution after undergoing a superficial parotidectomy. A diagnosis of undifferentiated neoplasm, favoring poorly differentiated carcinoma, was made at that time. He underwent a total parotidectomy and neck dissection at our institution. Microscopically, the tumor was composed of atypical spindle cells involving the parotid gland and an ipsilateral level III lymph node. Immunophenotypic analysis demonstrated positive staining for S100, fascin, vimentin, and HLA-II. Follicular dendritic cell, lymphoid, epithelial, myoepithelial, and melanoma markers were negative. Taken together, the above features were consistent with IDCS. An IDCS of the parotid gland is extremely rare, with only 2 cases reported in the literature. The unusual location and morphological similarity to follicular dendritic sarcoma and other types of soft tissue sarcomas can be a diagnostic challenge. Awareness of this tumor and the use of appropriate markers are crucial in making the diagnosis. The patient did well postoperatively, and he underwent a complete course of postoperative irradiation to the right parotid and neck.

Abstract
Histiocytic/dendritic cell sarcomas arising from follicular lymphoma are very rare and poorly understood lesions. We describe a case, which is unique in that it presented with a hipbone lesion simultaneously with axillary lymphadenopathy. Biopsy of the axillary lymph node showed a low-grade follicular lymphoma. The hipbone lesion was comprised two cell populations, one representing diffuse large B cell lymphoma and the other a histiocytic/dendritic sarcoma. The cells of all three lesions contained an IGH/BCL2 rearrangement, suggesting that both diffuse large B cell lymphoma and histiocytic/dendritic sarcoma differentiation developed from the same low grade precursor (follicular lymphoma). This case illustrates that sarcomatous transdifferentiation of follicular lymphoma can be an unpredictable local phenomenon and that it can occur extra nodally in the bone marrow. It may also occur concurrently with the progression of follicular lymphoma to a diffuse large B cell lymphoma.

Abstract
Interdigitating dendritic cell tumor/sarcoma is an extremely rare neoplasm that mainly occurs in the lymph node, with only 51 cases reported in the literature to date. The authors report the case of a 41-year-old woman who presented with a 4-month history of a gradually enlarging painless mobile lymphadenopathy in the right submaxillary region. The lymph node mass was completely resected and was treated with 1 cycle of CHOP chemotherapy. After 10 months, she was alive with no evidence of disease. Because interdigitating dendritic cell sarcomas are rare and can show morphologic and immunohistochemical heterogeneity, correct diagnosis requires a high index of suspicion and complete pathological study.

Abstract
Spindle cell neoplasms arising in the testis are uncommon; most cases belong to the category of gonadal stromal tumors, and the presence of distinctive clinical and pathological features usually lead to a definitive diagnosis. In some instances, however, the diagnosis of these tumors can be challenging and special techniques are needed. The present study reports 2 unusual cases of primary intratesticular tumors showing a striking morphology, characterized by spindle to stellate cells in a lymphoid background. The diagnosis of interdigitating dendritic cell tumor and inflammatory myofibroblastic tumor was established in the 2 cases, and their probable origin in cells of the accessory immune system is discussed. Although both tumors share similar histological features, their immunohistochemical profiles were decisive for a definitive diagnosis.

Abstract
Rare cases of histiocytic and dendritic cell (H/DC) neoplasms have been reported in patients with follicular lymphoma (FL), but the biologic relationship between the 2 neoplasms is unknown. We studied 8 patients with both FL and H/DC neoplasms using immunohistochemistry, fluorescence in situ hybridization (FISH) for t(14;18), and polymerase chain reaction (PCR)/sequencing of BCL2 and IGH rearrangements. There were 5 men and 3 women (median age, 59 years). All cases of FL were positive for t(14;18). The H/DC tumors included 7 histiocytic sarcomas, 5 of which showed evidence of dendritic differentiation, and 1 interdigitating cell sarcoma. Five H/DC tumors were metachronous, following FL by 2 months to 12 years; tumors were synchronous in 3. All 8 H/DC tumors showed presence of the t(14;18) either by FISH, or in 2 cases by PCR with the major breakpoint region (MBR) probe. PCR and sequencing identified identical IGH gene rearrangements or BCL2 gene breakpoints in all patients tested. All H/DC tumors lacked PAX5, and up-regulation of CEBPbeta and PU.1 was seen in all cases tested. These results provide evidence for a common clonal origin of FL and H/DC neoplasms when occurring in the same patient, and suggest that lineage plasticity may occur in mature lymphoid neoplasms.

Abstract
Interdigitating and follicular dendritic cell sarcoma (DCS) are very rare diseases, with approximately 184 cases being reported thus far, and their best treatment modality is still on debate. This is a review of all the cases of dendritic cell sarcoma reported from 1981 until April 2006. This review is enriched with the original contribution of five cases occurred at our Institution from 1994 to 2006. The review of the literature pointed out that radical surgery alone was curative in approximately two thirds of these cases, the relapsing rate in patients who received adjuvant treatments being higher than 30%. We pinpoint new five cases of dendritic cell sarcoma (three FDCS and two IDCS). Both the analytic revision of the literature and our data suggest that localized DCS may be effectively treated by radical surgery and do not support the use of adjuvant treatments after radical excision.

Abstract
The anuran Xenopus laevis is an experimental model for vertebrate development, immunology, and regenerative biology. Using histochemistry and immunohistochemistry (IHC) we examined embryonic, larval, and postmetamorphic Xenopus skin for the presence of dendritic cells (DCs), Langerhans cells (LCs), and dendritic epidermal T cells (DETCs), all components of cutaneous immunity that have been implicated in skin repair and regeneration. Cells expressing three markers for dendritic and Langerhans cells (formalin-resistant ATPase activity, major histocompatibility complex [MHC] class II antigens, and vimentin) and having morphology like that of these cells first appeared during late embryonic stages, becoming abundant by prometamorphosis. Cells positive for these markers were also numerous in the wound epithelia of regenerating hindlimbs at both early and late larval stages. Cells tentatively identified as DETCs were found, beginning at early larval stages, using IHC with antibodies against heterologous CD3epsilon chain and T-cell receptor delta. Further characterization and work with the putative DCs, LCs, and DETCs demonstrated here will allow not only greater understanding of the amphibian immune system, but also further elucidation of regenerative growth and scarring.

Abstract
A gradually enlarging axillary mass in a 79-year-old man was excised. The specimen was processed for light microscopy, immunohistochemical studies, and electron microscopy; gene rearrangement studies were also performed. A diagnosis of an interdigitating dendritic cell tumor of the lymph node and a B-cell small lymphocytic lymphoma occurring in the same anatomic location was made. We found that although rare cases of interdigitating dendritic cell tumor with an associated secondary malignancy have been described in the literature, to our knowledge, this is the first report of interdigitating dendritic cell tumor and synchronous neoplasm diagnosed at the same site. A possible relationship between the 2 disorders is also discussed.

Abstract
A case of a morphologically distinctive tumor of the adrenal medulla occurring in a 54-year-old woman is described. On microscopic examination, the tumor was well circumscribed and characterized by the presence of ill-defined, irregular nests of spindle cells with oval to elongated nuclei, tiny nucleoli, and abundant eosinophilic cytoplasm. The tumor was associated with a moderate infiltrate of lymphocytes and plasma cells with occasional lymphoid follicles. Necrosis, marked cellular atypia, and mitoses were absent. Immunohistochemical studies demonstrated the tumor cells to be strongly reactive for vimentin, S-100 protein, and CD56, and nonreactive for glial fibrillary acidic protein, chromogranin, synaptophysin, melanoma-associated antigens, and dendritic cell markers. Ultrastructural examination showed elongated cells with interdigitating cytoplasmic processes devoid of a basal lamina. No secretory granules were noted. The morphology, immunophenotype, and ultrastructure of this unique neoplasm suggest derivation from sustentacular cells of the adrenal medulla. We propose the designation "sustentaculoma" for this hitherto undescribed neoplasm of the adrenal gland.

Abstract
Abstract
Interdigitating dendritic cell sarcoma is an extremely rare malignancy derived from antigen-presenting cells. Dendritic cells constitute a heterogeneous group of cells, which includes Langerhans cells, dermal dendrocytes, follicular dendritic cells, and interdigitating dendritic cells present in lymphoid and nonlymphoid organs. We report the case of a 36-year-old woman who presented with epigastric pain, projectile vomiting, and significant weight loss. Upper gastrointestinal endoscopy showed a duodenal lesion; a biopsy of the lesion was taken and was diagnosed as sarcoma. She underwent a Whipple procedure. A final diagnosis of interdigitating dendritic cell sarcoma was made, with liver and peripancreatic lymph node involvement. The patient deteriorated rapidly and died 4 months later. Although interdigitating dendritic cell sarcoma of the duodenum is extremely rare, we think it should be included in the differential diagnosis of unusual spindle cell tumors with a rich lymphocytic infiltrate.

Abstract
Interdigitating dendritic cell sarcomas are extremely rare neoplasms with an unpredictable clinical course that usually occur in lymph nodes. We report the first adult patient with interdigitating dendritic cell sarcoma involving the bladder. A 71-year-old man presented with lower urinary tract symptoms and gross hematuria. Cystoscopy and transabdominal ultrasonography showed a large hyperechoic intravesical mass. The histologic analysis revealed a spindled cell neoplasm with an immunophenotype consistent with interdigitating dendritic cell sarcoma. Complete resection was achieved, and the patient was well without evidence of tumor 6 years after surgery. Urologists should be aware of this entity, which should be included in the differential diagnosis of bladder tumors.

Abstract
Interdigitating dendritic cell tumor (IDCT) is an extremely rare malignancy. It occurs primarily in lymph nodes, but extranodal involvement has also been reported. A 38-year-old woman with IDCT with breast and cervical lymph-node involvement is reported in this paper. To our knowledge, this is the first case of IDCT originating from the breast. In the breast and lymph node, the tumor displayed diffuse sheets, fascicles and storiform growth pattern. It was composed of oval to spindle cells with pale to eosinophilic cytoplasm, ill-defined cell outlines, oval nuclei with vesicular chromatin and prominent eosinophilic nucleoli. Mitotic activity was three per ten high-power fields. The neoplastic cells were intermingled with small mature lymphocytes and plasma cells. Immunohistochemical studies showed that the tumor cells were strongly and diffusely positive for vimentin, CD68, S-100 protein, CD45/leukocyte common antigen and fascin and focally positive for lysozyme, alpha-1 antitrypsin and CD4. Ki-67 labeling index was 10%. The patient was treated with combined therapeutic approaches, including surgery, radiotherapy and chemotherapy. IDCT has the potential for an aggressive clinical course. However, 32 months after the initial diagnosis, the patient is still alive and being followed with a stable tumor burden.

Abstract
Cell protrusions are outward extensions of the plasma membrane of individual cells that function in sensing the cell environment and in making initial, dynamic adhesions to extracellular matrix and other cells. Cell protrusions can be grouped into two major categories on the basis of morphology: localized, finger-like structures of highly defined shape and various lengths; or broad, irregular extensions of the plasma membrane. A key requirement of all cell protrusions is the need for a rigid cytoskeleton to support the localized extension of the plasma membrane. This is achieved either by a core unipolar bundle of actin microfilaments in finger-like protrusions, or by a combination of radial, rib-like, actin bundles integrated with a dendritic meshwork of microfilaments in the broad, lamellipodial protrusions. From studies of multiple cell types in vertebrates and invertebrates, fascin-1 has emerged as an actin-bundling protein of general importance for a diverse set of cell protrusions with functions in cell adhesion, cell interactions, and cell migration. This review discusses current knowledge of the molecular and cellular properties and functions of fascin, the roles of fascin-based protrusions in the cardiovascular system in health and disease, and areas of future interest.

Abstract
Tumors of dendritic reticulum cells are rare neoplasms that exhibit significant morphologic overlap with other malignancies. Fine-needle aspiration cytologic appearances of this neoplasm are not well understood. A 33-yr-old woman presented with a rapidly growing nodular mass in the right upper cervical region and right-sided ptosis. Fine-needle aspiration cytology of the mass showed dissociated as well as clustered, large, polygonal cells that showed high nuclear-cytoplasmic ratio. Nuclei were round, oval, or irregular in shape. Large and small blastoid forms with prominent nucleoli and chromatin clumping as well as binucleated cells and cells with lobulated nuclei were seen. Numerous mitoses were observed. The tumor cells expressed focal immunocytochemical reactivity to CD45 and CD68, but were negative for CD2, CD3, CD4, CD8, CD20, CD30, CD45RO, epithelial membrane antigen (EMA), cytokeratin, and HMB45. Histologic sections of the biopsy from the growth showed nodal tissue effaced by a tumor composed of large, pleomorphic neoplastic cells with some binucleate and multinucleate forms resembling Reed-Sternberg cells. The intervening stroma contained numerous small lymphocytes. Tumor cells expressed vimentin, S-100 protein, CD68, and MAC387, but were negative for LCA, CD1a, CD3, CD15, CD20, CD21, CD23, CD30, CD35, carcino-embryonic antigen, HMB45, cytokeratin AE1/3, EMA, myeloperoxidase, lysozyme, smooth-muscle actin, and desmin. The combined histologic and immunohistologic features suggested a histiocytic/dendritic reticulum cell neoplasm and a diagnosis of interdigitating dendritic reticulum cell sarcoma was made.

Abstract
While tumors of dendritic cell lineage may have overlapping histomorphologic features, most but not all cases can be classified using an immunohistochemical panel, including CD21, CD23, CD35, CD1a, and S-100. Based on observations that clusterin is expressed in benign follicular dendritic cells, clusterin expression in 32 dendritic cell tumors was evaluated. Diffuse strong staining for clusterin was seen in 12 of 12 follicular dendritic cell tumors. Two of these cases were negative for traditional markers (CD21, CD23, CD35); they were classified based on characteristic ultrastructural features. Three of 6 interdigitating dendritic cell tumors were negative for clusterin and 3 showed focal weak positivity. Clusterin staining in Langerhans cell histiocytosis ranged from negative (6 of 14) to weak/moderate (8 of 14). Follicular dendritic cell tumors behaved as benign tumors or low-grade sarcomas. Interdigitating dendritic cell tumors demonstrated a widely variable behavior, ranging from benign to rapidly fatal disease. Based on this initial study, strong clusterin staining supports a diagnosis of follicular dendritic cell tumor. Thus, staining for clusterin is useful in classification of dendritic cell tumors, particularly when the more common markers of follicular dendritic cells are not expressed.

Abstract
AIMS To report a series of four paediatric cases of interdigitating dendritic cell sarcoma (IDCS) and add to the known extranodal sites of occurrence for this tumour. Neoplasms derived from interdigitating dendritic cells are rare, with only 33 cases being reported in the literature (Medline search). These tumours usually occur in lymph nodes in the adult population. METHODS AND RESULTS The patients were a 10-year-old girl with a large soft tissue mass bulging into the left chest, a 12-year-old girl with a right paraspinal mass, a 21-month-old boy with generalized lymphadenopathy and hepatosplenomegaly and a 6-year-old girl with a large bladder mass. Paraffin blocks and haematoxylin and eosin slides were available in all cases. In addition, immunohistochemistry and electron microscopy were performed. A diagnosis of IDCS was made in all cases. CONCLUSION The diagnosis of IDCS can rarely be entertained on clinical information alone. Microscopically, there is a wide spectrum of features. Thus, immunohistochemistry and electron microscopy are crucial in making the diagnosis. The differential diagnosis includes inflammatory pseudotumour, follicular dendritic cell sarcoma, true histiocytic lymphoma, malignant Langerhans cell histiocytosis, anaplastic large-cell lymphoma, melanoma, and a range of sarcomas. IDCS displays aggressive behaviour and approximately half of the patients die of the disease.

Abstract
Sarcomas derived from immune accessory cells are uncommon malignancies, most of them occurring in lymph nodes while extra nodal sites are very rarely affected. Based on the immune profile, the cells that give origin to these neoplasms are currently divided in: follicular dendritic cell (FDC), interdigitating dendritic cell (IDC), indeterminate cell and Langerhans cell. A case of a dendritic cell sarcoma arising in the alveolar ridge mucosa in a 50-year-old female is reported here. The lesion presented as a nodular mass without defined borders and covered by reddish mucosa. Histologically, the tumour was composed of spindle-shaped cells with large nuclei and abundant cytoplasm, arranged in variable patterns as storiform and whorled and revealing interspersed lymphocytes. No capsule could be seen and the neoplasm extended up to the lining epithelium. Immunohistochemically, the spindle cells were positive for vimentin, S-100 protein, CD1a, factor XIIIa and focally to smooth-muscle actin, but were negative for CD21, CD35, CD23 and caldesmon--all markers of follicular dendritic cells. In conclusion, the present case has morphologic pattern of dendritic cell sarcoma and the immunophenotype is compatible with IDC cells or with intermediate dendritic cells and demonstrates the overlap of features among these entities.

Abstract
Interdigitating dendritic cell sarcoma (IDCS) is an extremely rare malignancy derived from professional antigen presenting cells. This report describes a case of IDCS arising in the salivary gland associated lymphoid tissue of the parotid gland of a 51 year woman, presenting with a painless neck swelling. Histologically, sheets of S100(+)/Ccd68(+)/CD45(+)/CD34(-)/CD1a(-) spindle cells were surrounded with an inflammatory infiltrate with no evidence of B or T cell clonal proliferations. No evidence of either human herpesvirus 8 or Epstein-Barr virus could be detected by quantitative polymerase chain reaction in the tumour cells with serological evidence of previous Epstein-Barr virus infection. The patient remains well and disease free 24 months after presentation without specific treatment.

Abstract
AIMS To detail on sequential biopsies the morphological and immunohistochemical features of a case of primary lymph nodal fibroblastic reticulum cell (FBRC) tumour which progressed into a clinically aggressive cytokeratin-positive interstitial reticulum cell (CIRC) sarcoma. METHODS AND RESULTS A 70-year-old female underwent surgical excision of an enlarged submandibular lymph node. The nodal architecture was effaced by a neoplastic proliferation of medium to large cells, round to oval to spindle in shape, growing in a storiform pattern. The tumour stained for vimentin, CD68, factor XIIIa, alpha1-antitrypsin, fascin and actin. Dendritic and endothelial cell markers were negative. A diagnosis of FBRC tumour was made by combining pathological and clinical data. The patient received no therapy but 5 months later the tumour relapsed, exhibiting a deceptively pleomorphic cytology, phenotypic changes (strong cytokeratin positivity), intense p53 expression and aggressive clinical course with fatal outcome. In-situ hybridization for Epstein-Barr virus was negative. CONCLUSIONS We speculate that the morphological changes and p53 expression of the relapsing neoplasm might reflect tumour cell dedifferentiation, in keeping with the aggressive clinical course. The intense p53 expression suggests that this oncoprotein might also play a role in reticulum cell tumorigenesis.

Abstract
Langerhans cell histiocytosis (LCH) is a clonal disorder believed to be derivedfrom cells of the dendritic system. Fascin, a 55-kd actin-bundling protein, represents a highly selective marker for dendritic cells of lymphoid tissues and peripheral blood and is involved in the formation of dendritic processes in maturing epidermal Langerhans cells. Since lesional cells of LCH may represent Langerhans cells arrested at an early stage of activation, immunohistochemical expression offascin in epidermal Langerhans cells and in the lesional cells of 34 cases of LCH was evaluated in paraffin sections using an immunoalkaline phosphatase technique. Though epidermal Langerhans cells were nonreactive for fascin, lesional cells in all LCH cases exhibited immunoreactivityforfascin, CD1a, and S-100 protein. Variation in staining intensity was observed in some cases, possibly reflecting differences in cell maturation or activation. Involved tissues included bone, soft tissue, lymph node, thyroid, orbit, and extradural cranial tissue. Immunoreactivity of lesional cells of LCH for fascin supports their derivation from cells of the dendritic system and represents another alteration in the phenotype of Langerhans cells that is associated with maturation, migration, culture, or clonal expansion.

Abstract
BACKGROUND Fascin containing actin bundles provide mechanical support to cellular protrusions and stress fibers. In cancers, some malignant cells (e.g. subsets of breast and ovarian carcinomas) express fascin. In skin cancer, the role of fascin is unknown. METHODS Cases of 61 keratocytic neoplasms, 35 melanocytic neoplasms, nine extramammary Paget's disease (four with adenocarcinoma) and five sarcomas (angiosarcoma and atypical fibroxanthoma) were examined by immunohistochemistry, using monoclonal antihuman fascin antibody, clone 55 k-2 (Dako Corporation, Carpinteria, CA, USA). RESULTS Fascin labeled all sarcomas and all keratinocytic neoplasms except for pagetoid pattern Bowen's disease. The regions of most intense fascin labeling were seen in the basal cells of infiltrative tumor margins. A minority of Merkel cell carcinomas exhibited weak or absent immunoreactivity. All melanocytic nevi except for some junctional nests of dysplastic melanocytic nevi expressed fascin. However, pagetoid cells of melanoma in situ and epithelioid cells of invasive melanoma weakly expressed or did not express fascin, whereas melanoma cells exhibiting spindle cell morphologies labeled intensely with fascin. Lastly, all cells of extramammary Paget's disease and most associated adenocarcinomas cells did not or were faintly labeled by fascin antibodies. Decreased or absent fascin expression was significantly associated with skin cancers with a high risk for metastasis (e.g. melanoma) vs. those with a low risk (e.g. basal cell carcinoma) (24% vs. 100% with > 50% immunoreactivity; p = 0.0001, chi-squared test). CONCLUSION Fascin is expressed by skin tumors that locally infiltrate and replace surrounding tissues indicating a role for fascin in cell adhesion, cell motility and invasiveness. No or weak fascin expression is exhibited by cancers with pagetoid intraepidermal spread and by invasive tumors with a high risk of metastasis. Downregulation or loss of fascin's actin-bundling properties, probably associated with disorganization of cell-cell and cell-matrix contacts, may be a crucial step in the progression from locally invasive to widely disseminating cancers.

Abstract
The fascins are a structurally unique and evolutionarily conserved group of actin cross-linking proteins. Fascins function in the organisation of two major forms of actin-based structures: dynamic, cortical cell protrusions and cytoplasmic microfilament bundles. The cortical structures, which include filopodia, spikes, lamellipodial ribs, oocyte microvilli and the dendrites of dendritic cells, have roles in cell-matrix adhesion, cell interactions and cell migration, whereas the cytoplasmic actin bundles appear to participate in cell architecture. We discuss the current understanding of the cellular mechanisms that regulate the binding of fascin to actin and how these processes contribute to the organisation or disassembly of cell protrusions. Although the in vivo roles of fascin have been studied principally in Drosophila, several human diseases are associated with inherited or acquired alterations in the expression of fascins. Strategies to modulate fascin-containing protrusions and thereby cell adhesive and migratory behaviour could have potential for therapeutic intervention in these conditions.

Abstract
Interdigitating dendritic cell sarcoma is an extremely rare neoplasm that mainly occurs in the lymph nodes. We report a case of interdigitating dendritic cell sarcoma arising from the spleen, a previously unreported site for interdigitating dendritic cell sarcoma. An 87-year-old woman, visiting Ashigara Hospital with complaints of palpitation and dyspnea, was found to have pancytopenia and low proteinemia. Abdominal ultrasonography and CT scanning demonstrated severe splenomegaly with heterogeneous enhancement. She received a splenectomy under the clinical diagnosis of a splenic tumor. Grossly, the spleen was markedly enlarged, with confluent massive nodules. Microscopically, the normal architecture was effaced with diffuse proliferation of large pleomorphic cells arrayed in a somewhat sheet-like pattern. Erythrophagocytosis was commonly observed. Immunohistochemical studies showed that the tumor cells were positive for S-100 protein, fascin, vimentin, and CD68, but uniformly negative for CD45, B- and T-cell markers, CD1a, CD30, complement receptors, CD34, Factor VIII, HMB-45, and lysozyme. Ultrastructurally, the tumor cells possessed complex interdigitating cytoplasmic dendritic processes. Birbeck granules were absent. Based on these findings, the present case was diagnosed as interdigitating dendritic cell sarcoma. The patient died of multiple liver metastases 3 months postoperatively.

Abstract
Extranodal follicular dendritic cell (FDC) sarcoma of the head and neck region is uncommon, with 16 well-documented cases previously reported (four in the tonsil, four in the pharynx, two in the palate, five in the soft tissue, and one in the thyroid). We here report an additional three cases of extranodal FDC sarcoma in the tonsil (two cases) and pharynx (one case). In these new cases, the neoplastic cells were arranged in diffuse, fascicular, and vaguely whorled growth patterns. A background lymphocytic infiltrate was sprinkled throughout the neoplasms, with focal prominent perivascular cuffing. Scattered multinucleated giant cells were present. Immunohistochemically, tumor cells were strongly and diffusely positive for follicular dendritic cell markers CD21 and CD35. Tumor cells were diffusely positive for fascin and negative for leukocyte common antigen, S-100 protein, cytokeratin, and Epstein-Barr virus (EBV) latent membrane protein-1 (EBV-LMP). EBV was also not detected in the tumor cells by in situ hybridization for EBV-encoded RNAs. FDC sarcomas are probably an underrecognized neoplasm, especially when they occur in extranodal sites in the head and neck region. Two of the three new cases we report were initially misdiagnosed, and five cases of extranodal FDC sarcoma in the head and neck region reported in the recent literature were initially misdiagnosed. Our aim is to complement the current understanding of this neoplasm and alert pathologists to this rare entity in this region to avoid misdiagnosis. Recognition of extranodal FDC sarcoma requires a high index of suspicion, but this tumor has numerous distinctive histological features that should bring the neoplasm into the differential diagnosis. Confirmatory immunohistochemical staining with follicular dendritic cell markers such as CD21 and/or CD35 is essential for the diagnosis. Correct characterization of this neoplasm is imperative given its potential for recurrence and metastasis.

Abstract
True histiocytic lymphoma, as defined by strict criteria, is a very rare neoplasm. We describe three cases occurring as primary tumors in the central nervous system. The patients, two females and one male, ranged in age from 11 to 69 years. The tumors involved the brain in two cases and spinal cord in one, with a size ranging from 7 to 17 mm. Two patients died at 4 months and 8 months, respectively, and one was alive with disease at 5 months. Pathologically, the tumors comprised groups and sheets of noncohesive large cells with pleomorphic vesicular nuclei, distinct nucleoli, and abundant eosinophilic cytoplasm. A dense inflammatory infiltrate consisting of neutrophils, lymphocytes, plasma cells, and histiocytes was present, with multiple foci of necrosis and abscess formation. All three cases demonstrated an identical immunophenotype: positive for CD68 and lysozyme; focally positive for S-100 protein, CD45RB, and CD4; and negative for CD3, CD20, CD21/CD35, CD1a, CD30, ALK1, myeloperoxidase, glial fibrillary acidic protein, and cytokeratin. The proliferative index ranged from 20% to 35%. Ultrastructural examination further confirmed the histiocytic nature of the tumor cells, characterized by irregularly folded or multisegmented nuclei and abundant cytoplasm containing lysosomes; Birbeck granules, interdigitating cell processes, and cell junctions were not found. Although the presence of abundant inflammatory cells could obscure the neoplastic histiocytes, making the distinction from inflammatory conditions difficult, awareness of this unusual histologic feature and the invariable finding of pleomorphic cells in some areas of the lesion permit the correct diagnosis to be made.
