Abstract
AIMS The histological, immunohistochemical and electron microscopic features of a primary adenomyoepithelioma of skin, a rare sweat gland tumour, are reported. METHODS AND RESULTS The tumour occurred on the back of a 92-year-old woman. It was composed of well-formed tubules lined by epithelial cells surrounded by clear or spindled myoepithelial cells. Immunohistochemically, the epithelial cells exhibited strong cytokeratin (CAM5.2) and weak carcinoembryonic antigen positivity. The myoepithelial cells showed diffuse positivity for smooth muscle actin and focal positivity for S100 protein. Ultrastructurally, the myoepithelial cells contained myofilaments with focal densities and hemidesmosomes. They were limited by well-formed basal lamina. The tumour was associated with a small eccrine spiradenoma. CONCLUSION We predict that the tumour will behave in a benign fashion. There is no evidence of recurrence or metastasis 28 months later.

Abstract
AIMS To study the clinical and pathological features of primary malignant peripheral primitive neuroectodermal tumours (PNETs) of the skin and subcutaneous tissue, to discuss the differential diagnosis, and to review the existing literature on these tumours. METHODS AND RESULTS Eight cases of PNETs presenting in the skin and subcutaneous tissue were identified from the pathology records of the Christie Hospital, Manchester. Detailed immunohistochemical studies were performed on all cases and seven tumours were subjected to electron microscopic examination. Detailed clinical and follow-up information was obtained on seven cases. Six tumours occurred in children and adolescents and two were seen in young adults (age range, 8-36 years). No sex or site predilection was observed. Five tumours occupied the dermis and subcutis and three were entirely located in the subcutaneous tissue. Microscopically, they were composed of small round cells and seven tumours contained glycogen. Only one tumour focally exhibited Home-Wright rosettes and neuropil. Two tumours contained rhabdoid or plasmacytoid cells in places and all cases showed microcystic and pseudovascular spaces. Immunostains revealed MIC2 (8/8), NSE (7/8), PGP9.5 (7/8), beta 2 microglobulin (7/8), neurofilament protein (6/8), S100 protein (3/8), synaptophysin (2/8) and Leu-7 (1/8) positivity. Anomalous cytokeratin (4/8), desmin (2/8), myoglobin (2/8), NKIC3 (4/8) and GFAP (1/8) staining was also noted. Ultrastructurally, neuroendocrine granules were detected in five cases and one case exhibited microtubules in processes. Adequate follow-up information was available in four cases. One patient died of metastatic disease. One child developed axillary lymph node metastasis but is alive with no evidence of disease 96 months after treatment. Two other patients are alive with no residual or recurrent disease 44 and 52 months after excision and radio/chemotherapy. CONCLUSION PNETs are rare malignant small round cell tumours of the skin and subcutaneous tissue which are probably underdiagnosed. A correct diagnosis can be made on light microscopic features, demonstration of neuroendocrine granules on electron microscopy and a combination of MIC2, beta 2 microglobulin, and more than one neural marker positivity. These neoplasms should be differentiated from other cutaneous neoplasms composed of small round cells. The number of cases of cutaneous PNETs studied so far is rather small, and no firm conclusion can be drawn about their behaviour but long-term survival is possible in some cases.

Abstract
AIMS We describe the cutaneous pseudoneoplastic lesions in two patients with nodular erythema elevatum diutinum, a rare chronic disorder in which polymorph nuclear fragmentation (leukocytoclasis) is present within dermal nodules showing spindle cells and fibrosis. In both cases diagnostic difficulty was encountered clinically and pathologically and various benign and malignant neoplasms were considered in the differential diagnosis. METHODS AND RESULTS Immunohistochemically the spindle cells were negative for CAM5.2, AE1/3, S100 protein and desmin (D33). They were positive for vimentin and focally positive for CD34 and alpha-smooth muscle actin. Some of the spindle cells were positive for Mac 387 and KP1(CD68). By electron microscopy, the lesions were shown to consist of fibroblasts/myofibroblasts and fusiform macrophages. CONCLUSIONS Increased awareness of the features described will help to avoid misdiagnosis as a neoplastic process.

Abstract
VS38 was originally described as a marker of neoplastic and non-neoplastic plasma cells. We recently described its immunoreactivity with melanocytic lesion. The aim of the present study was to investigate the reactivity of VS38 with various neuroendocrine tumours. Using paraffin sections of routinely processed archival tissue we found that 72% of 50 neuroendocrine tumours tested showed immunohistochemical positivity for VS38. A wide spectrum of neuroendocrine tumours were positive. Use of a panel of markers and awareness of the lack of specificity of VS38 will avoid misdiagnosis, particularly when neuroendocrine tumours and other lesions which react immunohistochemically with this antibody are located at unusual sites and exhibit plasmacytoid features.

Abstract
Extramedullary plasmacytomas (EMP) of head and neck are rare tumours. Between 1972 and 1993, 25 cases of EMP of head and neck were seen at our institute. The clinical and pathological features and response to treatment are presented. At initial presentation, 23 (92%) patients presented with disease confined to a single extramedullary site only and two patients had in addition clinical involvement of cervical lymph nodes. All except these two patients received radiotherapy to the primary site only as initial treatment. Initial primary control of local disease was obtained in 16 of 24 (67%) patients treated with radical intent. With salvage treatment of further radiotherapy and/or chemotherapy, local disease control was achieved in 21 of 24 (88%) patients. One patient was treated with palliative intent. Conversion to multiple myeloma was seen in two patients (8%). Pathologically, the tumours were classified into low, intermediate and high grade, which correlated closely with outcome. This classification has been used for the first time in extramedullary plasmacytomas and is based on the multiple myeloma grading criteria devised by Bartl et al (1987). Fifteen of eighteen (83%) low-grade tumours and only one of six (17%) intermediate- and high-grade tumours were locally controlled after primary radiotherapy. This is statistically significant for local control (P= 0.0019) but not for overall survival (P= 0.12). The median survival and 5-year overall survival is 68 months and 58.9% respectively. We recommend consideration of adjuvant chemotherapy in patients with higher grade disease.

Abstract
A unique case of a metastatic non-desmoplastic sarcomatoid malignant melanoma in an axillary lymph node showing smooth muscle differentiation in a 54 year old woman is described. The tumour cells exhibited alpha-smooth muscle actin, HHF-35 and desmin positivity but were negative for S100 protein and HMB-45. Ultrastructural examination revealed smooth muscle phenotype and there was no evidence of myofibroblastic differentiation, a feature described previously in desmoplastic melanomas.

Abstract
Olfactory neuroblastoma is an uncommon tumour arising in the nasal cavity or paranasal sinuses. We report the management of nine cases treated with external beam radiotherapy subsequent to surgery, either attempted definitive removal or biopsy only. Recent refinements in pathological evaluation of these tumours are discussed. Seven cases were deemed classical olfactory neuroblastoma whilst two were classified as neuroendocrine carcinoma. The clinical features, radiotherapy technique and variable natural history are presented. Seven of eight patients treated radically were controlled locally, with a minimum follow-up of two years. Three patients developed cervical lymph node disease and three patients died of systemic metastatic disease. Suggestions are made as to which patients should have en-bloc resection rather than definitive radiotherapy.

Abstract
A unique case of primary myxoid liposarcoma of the thigh, in which focal pleomorphic areas were present containing rhabdomyoblasts, is described. Focal rhabdomyosarcoma in liposarcoma has only rarely been reported previously and only in dedifferentiated liposarcomas of the retroperitoneum. All but one have been recurrences with rhabdomyoblasts being absent in the primary liposarcoma. As rhabdomyoblasts were only focally present, the present case is regarded as liposarcoma with focal divergent rhabdomyoblastic differentiation rather than malignant mesenchymoma.

Abstract
We describe the clinicopathological features of gastrointestinal autonomic nerve tumours in nine patients where the diagnosis was confirmed by electronmicroscopy. Most patients presented with abdominal pain. At laparotomy, large intra-abdominal tumour masses were found which tended to be cystic and haemorrhagic. The predominant histological patterns were nests, sheets and fascicles of spindle and epithelioid cells. Immunohistochemistry showed positive staining for neuron specific enolase (9/9), PGP 9.5 (9/9), NKI/C3 (7/9), vimentin (7/9), alpha-smooth muscle actin (5/9), vasoactive intestinal peptide (3/9) and CD34/QBend10 (2/9). Grimelius staining was positive in two of nine cases. All tumours were negative for CAM 5.2, chromogranin, synaptophysin, Leu 7, neurofilament protein, muscle-specific actin (HHF-35) and desmin (D33). Ultrastructural examination showed cellular processes and dense-core granules in all cases. Three tumours had microtubules and/or intermediate filaments, particularly in cell processes. Skeinoid fibres were seen in three cases. No convincing synapses or small (synaptic-type) vesicles were identified. There was no evidence of epithelial, smooth muscle or nerve sheath differentiation. Two patients died due to tumour, two died of unknown causes and the remainder are alive 2-44 months after presentation. Four of the five survivors have recurrent/residual intra-abdominal tumour. So-called gastrointestinal autonomic nerve tumours are apparently slow-growing malignant tumours showing neuronal differentiation. Four cases arose in the mesentery/retroperitoneum or omentum rather than bowel wall and therefore a more appropriate nomenclature might be intra-abdominal stromal tumour with neuronal differentiation.

Abstract
Prognostic factors predicting for breast recurrence following breast conserving surgery and radiotherapy have been identified in a prospective randomised trial comparing two different radiotherapy techniques. The first used megavoltage radiation to encompass the whole breast and regional nodes (WF group). The second used an electron field directed to the tumour bed only (LF group). With a median follow up of 8 years survival in both groups was the same (72%). There was an increased rate of breast recurrence in the LF group: 25%, compared to the WF group: 13% (P = 0.00008), expressed in actuarial terms at 8 years. In a multivariate analysis of factors predicting for breast recurrence, once the difference in treatment technique is allowed for, only two factors were found to be significant: histological grade (P = 0.013) and lymphovascular invasion in the histological specimen (P = 0.037).

Abstract
Four cases of malignant peripheral nerve sheath tumour showing vascular differentiation are described. One case was associated with neurofibromatosis 1 and contained angiosarcomatous, cartilaginous and rhabdomyoblastic elements. The other cases occurred in patients without neurofibromatosis and showed a spectrum of vascular lesions ranging from lobulated, haemangioma-like structures to angiosarcoma. These are the first recorded examples of this phenomenon not associated with neurofibromatosis. Immunohistochemical examination demonstrated the endothelial nature of the lesions in all cases and revealed cells positive for alpha-smooth muscle actin, probably pericytes, closely apposed to the endothelium.

Abstract
The histological, immunohistochemical, and ultrastructural features of a primary small cell neuroendocrine carcinoma of the renal parenchyma are described. Tumor cells were positive for cytokeratin, neuron-specific enolase, and Leu 7, but Grimelius- and chromogranin-negative. They also exhibited positivity with anti-MIC2 antibody. By electron microscopy, tonofibrils, primitive desmosomes, and dense-core granules with a neuroendocrine appearance were present. This is only the 7th recorded example of such a tumor at this site, which showed an aggressive course characterized by widespread bony metastases.

Abstract
AIMS To investigate the immunoreactivity of a range of melanocytic lesions, both benign and malignant, with the monoclonal antibody VS38. This was recently described as a marker of reactive/neoplastic plasma cells and, therefore, is useful in the diagnosis of plasmacytoma/myeloma and lymphomas with plasmacytic differentiation. This study was prompted by the recent observation that a plasmacytoid melanoma arising in the nasal cavity was strongly immunoreactive with VS38, which was therefore a potential source of major diagnostic error. METHODS The Streptavidin-peroxidase complex technique was used on paraffin wax embedded sections of 167 melanocytic lesions. Diaminobenzidine (DAB) was used as chromogen for non-pigmented or lightly pigmented lesions and nickel/DAB for more heavily pigmented lesions. RESULTS Positive immunostaining for VS38 was seen in 14.5% (10/69) of benign naevi (including 40% (four of 10) of Spitz naevi), 10.5% (two of 19) of dysplastic naevi/in situ melanomas, 92% (35/38) of primary cutaneous melanomas, 100% (four of four) of primary mucosal melanomas, 91.7% (33/36) of recurrent/metastatic melanomas, and 100% (one of one) of clear cell sarcomas of soft tissues. CONCLUSIONS VS38 immunostaining is frequently positive in primary and recurrent/metastatic malignant melanoma and is also reactive less commonly with benign naevi. These results should be borne in mind when this recently described marker of normal/neoplastic plasma cells is used to identify tumour lineage, particularly in tumours arising at unusual sites, such as in the nasal cavity. The possibility of malignant melanoma should be actively considered and excluded in any undifferentiated tumour which shows VS38 immunoreactivity.

Abstract
Palisaded myofibroblastoma (hemorrhagic spindle cell tumor) is a recent addition to the group of benign primary spindle cell lesions of lymph nodes. These tumors are characterized histologically by hemorrhage, palisading, and foci of collagen called amianthoid fibers. We report a further typical example with the aim of discussing its differentiation. Tumor cells were positive for smooth-muscle actin and vimentin. The cytoplasm contained moderate numbers of rough endoplasmic reticulum cisternae and some smooth-muscle type myofilaments. Subplasmalemmal densities and plasmalemmal caveolae, as well as material interpreted as external lamina, were identified at the cell surface, whereas the fibronexus junctions typical of myofibroblasts were not seen. Immunostaining for type IV collagen was positive. Intranodal myofibroblastomas have largely been considered as myofibroblastic, but the observations presented here raise the alternative possibility of simple smooth-muscle differentiation. The foci of collagen widely referred to as amianthoid fibers contained fibrils mostly of conventional diameter, 50-83 nm. The giant collagen fibrils typical of true amianthoid change were absent. It is suggested that the term amianthoid be used only after ultrastructural confirmation of the presence of giant collagen fibrils.

Abstract
AIMS To analyse the diagnostic differences in reporting tumour histopathology between a district general hospital and a regional oncology centre. METHODS Tumour histopathology reports (n = 227) extracted from Bolton General Hospital files between 1988 and 1992 were compared with the corresponding Christie Hospital (oncology centre) reports, the same material having been seen at both hospitals. RESULTS Diagnostic agreement existed in 77% of all cases. The incidence of major discrepancies was 8.37%. Of the diagnoses, 19 (36%) cases involved major discrepancies and 34 (64%) cases minor discrepancies. Most discrepancies occurred in the lymphoma group and involved subclassification of Hodgkin's and non-Hodgkin's lymphoma. Ki1 anaplastic large cell lymphoma and T cell rich B cell lymphoma were problematic diagnoses. The correct grading of follicle centre cell lymphomas using the Kiel classification was another problem area. In 19 cases certain aspects of immunohistochemistry produced discrepancies. In one case an incorrect diagnosis was made at the oncology centre and in another both centres gave an incorrect diagnosis. CONCLUSIONS Areas of diagnostic difficulty mainly involve the subclassification of lymphomas. Review of tumour pathology by experts is recommended, at least in certain categories, to ensure correct diagnosis and uniformity in subclassification of tumours.

Abstract
AIM To describe the clinical, histological and immunohistochemical features in four cases of an uncommon benign lymph node lesion which may mimic a neoplastic process. METHODS Four cases of inflammatory pseudotumour of lymph nodes were studied using conventional staining (haematoxylin and eosin, PAS, Gordon and Sweets reticulin stain, and the Ziehl-Neelsen stain) and with immunohistochemical techniques using a variety of antibodies (CD3, L26, CD15, CD21, CD30, KP1, MAC 387, vimentin, alpha SMA, HHF-35, D33, CD34, and S100). RESULTS The lesion comprises a proliferation of spindle cells expanding the connective tissue framework of lymph nodes and is associated with a plasma cell and small lymphocyte infiltrate. There are variable numbers of macrophages, neutrophils and eosinophils, and varying degrees of fibrosis. Vascular changes are common but vary in degree and type. CONCLUSIONS Inflammatory pseudotumour of lymph nodes is an uncommon benign reaction pattern which may be misdiagnosed as a neoplastic or even a malignant process. Increased awareness of its histological features should help prevent such misdiagnoses.

Abstract
Four cases of cutaneous epithelioid angiosarcoma are described together with the potential diagnostic trap of mistaking these tumours for poorly differentiated carcinoma or malignant melanoma. The immunophenotypic profile using four endothelial markers showed positive staining in all cases for factor VIII related antigen in a predominantly paranuclear dot-like fashion and for CD31 (JC70); in three cases for CD34 (QB-END/10) and in two cases with UEA-1. All four cases were cytokeratin (CAM 5.2 and AE1/AE3) negative in contrast to the positive staining reported at non-cutaneous sites. Aberrant S-100 protein expression was seen in one case. In two cases subsequent recurrences showed better differentiation than the original tumour. Electronmicroscopy confirmed the absence of non-endothelial lines of differentiation but failed to reveal Weibel-Palade bodies.

Abstract
A lipid rich rhabdomyosarcoma of the paratesticular region was studied by light microscopy, histochemistry, immunohistochemistry and electron microscopy. The tumour was composed of primitive looking, vacuolated, and pleomorphic cells. Lipid was present in varying amounts in all cells but was especially abundant in the vacuolated and pleomorphic cells. Some cells showed eosinophilic fibrillary cytoplasm but cross-striations were not seen. Tumour cells were positive for desmin, muscle specific actin, and vimentin. A few cells were myoglobin positive. At electron microscopy, the presence of lipid was confirmed, while thick and thin filaments, Z disks, lamina and glycogen were observed, thereby confirming striated muscle differentiation. Although moderate amounts of lipid can be expected in almost any tumour, lipid rich rhabdomyosarcomas have received little attention. The present report provides a comprehensively examined case of such a tumour initially presenting diagnostic difficulty because of its possible confusion with liposarcoma.

Abstract
Multiple primary tumours occurring in a three-year population-based series of patients with histopathologically peer-reviewed sarcomas from North West England were ascertained in order to look at the patterns of neoplasms seen. A total of 30 out of the 310 patients entered in the study had additional primary tumours. Very few patients were aged under 60 years at diagnosis of both their malignancies. The youngest was a known case of neurofibromatosis and, although seven patients were diagnosed with a sarcoma and carcinoma of the breast--a combination of cancers characteristic of the Li-Fraumeni cancer family syndrome--no other patients could directly be identified as suffering from any other cancer predisposition syndrome.

Abstract
The clinical, histological and immunohistochemical findings in five primary lymphomas of the urinary bladder are reported. One patient had both lymphoma and transitional cell carcinoma of the bladder. All of the lymphomas showed histological features of mucosa-associated lymphoid tissue (MALT) lymphomas with centrocyte-like cells in all cases. One patient with pre-existing cystitis glandularis showed lymphoepithelial lesions. Biopsies from four patients contained reactive germinal centres and, in two of these, there was follicular colonization by tumour cells. In three patients, repeat biopsies, over several years, showing the changes of MALT lymphoma, were diagnosed as cystitis. We suggest that a large proportion of primary lymphomas of the bladder are lymphomas of MALT and that the characteristic morphological and immunohistochemical features of these tumours should be sought in biopsies containing large numbers of lymphoid cells.

Abstract
An immunohistochemical study of 106 malignant melanoma specimens from 59 patients, using formalin-fixed, paraffin-embedded material, is reported. Negativity for HMB-45 was seen in 11% of specimens. The rate of positivity with CAM 5.2 was 7%. One specimen showed alpha-smooth muscle actin (alpha SMA) positivity. For 11 of the 12 cases in which anomalous immunophenotypes were seen, multiple specimens were available; nine of these showed evidence of an alteration in the immunophenotype between specimens. Comparing the primary tumours with local recurrences and metastases, there was, variously, loss of HMB-45, S-100 protein and NKI/C3 positivity, and acquisition of CAM 5.2 and alpha SMA positivity. In some cases, the change of immunophenotype appeared to occur in a single step. However, one case with six consecutive specimens showed evidence of progressive loss of HMB-45, S-100 protein and NKI/C3 with concomitant gain of CAM 5.2 staining. The implications for the use of immunophenotyping in diagnostic practice are discussed.

Abstract
A series of 10 small round-cell tumours, having in common evidence of neural differentiation, were investigated by immunohistochemistry and electronmicroscopy. In seven, evidence of divergent muscle and/or epithelial differentiation was found. This phenomenon thus appears more common than previously appreciated and suggests that there may be a continuous and overlapping phenotypic spectrum from Ewing's tumour of soft tissue to intra-abdominal desmoplastic small cell tumour.

Abstract
A case of primary large cell splenic lymphoma of B lineage exhibiting filiform cell appearance is reported. The patient presented with massive splenomegaly, and following spontaneous splenic rupture, died of adult respiratory distress syndrome. The clinical aspects of the case, notably a lymphoma arising as a primary tumour in the spleen, with spontaneous spleen rupture and rapid fatal outcome, in combination with the filiform appearance of the lymphoma on electron microscopic examination, constitute an unusual combination of features. As far as is known, this B cell neoplasm is only the second primary splenic lymphoma of filiform type to be recorded.

Abstract
Four cases of chondroid syringoma containing large numbers of hyaline or plasmacytoid cells are described. Three cases occurred in the hand and one in the foot. Hyaline cells are commonly seen in mixed tumours and myoepitheliomas of salivary glands and rarely in chondroid syringomas. The hyaline-cell change in three of the cases initially caused diagnostic difficulties and the possibility of sarcoma was raised in two cases. In addition to the characteristic hyaline cells, the presence of tubulo-glandulo-ductal structures, benign squamous epithelium and myxochondroid stroma aided diagnosis. Immunohistochemically, the hyaline cells exhibited positivity for vimentin, cytokeratin, S-100 protein, carcino-embryonic antigen, focal glial fibrillary acidic protein (3 cases), neuron-specific enolase (3 cases) and focal alpha-smooth muscle actin (2 cases). Occasional cells were Ber EP4 positive (2 cases). In some cells, a striking peripheral ring-like positivity for cytokeratin and S-100 protein was noted. Ultrastructurally, desmosomes, varying numbers of tonofibrils and non-bundling intermediate filaments were seen. Scanty fine filaments with vague focal densities were detected in some cells. Our studies suggest that the hyaline cells represent modified epithelial as well as myoepithelial cells. One of our cases also exhibited collagenous spherulosis.

Abstract
In 1990, we published the results of a clinical trial involving 708 patients with breast carcinoma of 4 cm or less in diameter, who, following lumpectomy, were randomized to have radiotherapy to the tumour bed only (limited field, LF group) or to the whole breast and regional nodes (wide field, WF group). No adjuvant systemic therapy was prescribed. At the time the median follow-up was 37 months. We present the updated results after an extended median follow-up of 65 months. The overall survival is 72.7% and 71.2% for the LF and WF groups respectively. The actuarial breast recurrence rate (first event) is 15% (LF) versus 11% (WF) for infiltrating ductal carcinoma, whereas, for infiltrating lobular carcinoma, the recurrence rate was 34% (LF) versus 8% (WF). A high actual recurrence rate of 21% (LF) and 14% (WF) was also found for extensive ductal carcinoma in situ. It was extremely rare for medullary, mucoid or tubular carcinomas to recur. Salvage surgery was possible in 86% (LF) and 90% (WF) respectively. The recurrence rate in the breast following lumpectomy and wide field irradiation is comparable with others reported in the literature. This trial also shows the lumpectomy with limited field irradiation is feasible, albeit with a higher breast recurrence rate; the latter could be reduced by improved selection and refinement of the technique.

Abstract
Survival data on a population-based series of bone, soft tissue and visceral sarcomas diagnosed in the North West of England between 1982-84 and subjected to histopathological peer review are presented. Five-year crude survival for all cases was 34%. Survival in males and females did not differ significantly (P = 0.6, 5-year survival 32% vs 36%) but was markedly worse for patients diagnosed over the median age of 60 years, even when allowance was made for underlying mortality (P = 0.03, 34% vs 44%). Five-year survival rates for the major site groups were: bone 44%; soft tissues of head, neck and trunk 36%; soft tissues of extremities 35%; female genital tract 35%; retroperitoneum 15%; gastro-intestinal tract 13%. Analysis by the major histological types revealed the following survival rates: leiomyosarcoma--female genital tract 25%, gastro-intestinal tract 14%, non-visceral soft tissue 21%; malignant fibrous histiocytoma of soft tissue 29%; liposarcoma 52%; osteosarcoma of bone 46%; and chondrosarcoma of bone 50%.

Abstract
AIMS To study the pathological features of fungal infections affecting the lower intestinal tract (duodenum, small and large bowels). METHODS Between mid-1981 and mid-1991, 14 cases of deep mycotic infections affecting the lower intestinal tract were found among 890 consecutive necropsies on patients with malignant disease treated in a regional cancer centre (incidence 1.6%). These 14 cases accounted for 54% of all gastrointestinal fungal infection detected. The relevant clinical, necropsy, histological and microbiological data were reviewed. RESULTS Candida spp and Aspergillus spp accounted for all infections. The macroscopic appearances included ulcers of varying configuration, mucosal flecks, sloughed mucous membranes, polypoid masses and segmental lesions. Either organism could produce this range of lesions, but Candida tended to have a mucosal location and Aspergillus was associated with transmural invasion. Combined infections showed Candida in the surface mucosa and Aspergillus hyphae in submucosal vessels with spread into the bowel wall in a radiating pattern. During the final illness, gastrointestinal symptoms and signs were often slight and microbiological investigations were unhelpful. CONCLUSIONS Variable gross appearances are relevant for endoscopists, particularly lesions which resemble pseudomembranous colitis. Endoscopic biopsy specimens may have a role in antemortem diagnosis. Failure to diagnose these infections during life emphasises the importance of necropsy in the clinicopathological audit of deaths in this group of patients.

Abstract
Seven cases of carcinoma mimicking angiosarcoma occurring in skin (3 cases), breast (3) and lung (1) are described. The cutaneous, pulmonary and one of the breast carcinomas were poorly differentiated and squamous in type; the other two breast tumours were poorly differentiated ductal carcinomas with focal squamous differentiation. Histologically, the pseudoangiosarcomatous pattern was due to complex anastomosing channels and spaces lined by neoplastic cells. The spaces contained hyaluronic acid. The neoplastic cells exhibited cytokeratin positivity but yielded negative results with the endothelial cell markers, factor VIII-related antigen and CD 34 (QB-END/10). Two breast tumours showed binding of UEA-1. Ultrastructurally, unequivocal epithelial differentiation was demonstrated in six of the cases. Pathogenetically, these tumours appeared to be variants of acantholytic squamous cell carcinoma. Recognition of this unusual form of carcinoma is important, as an incorrect diagnosis of angiosarcoma may lead to inappropriate treatment and prognostication.

Abstract
Neutropenic colitis is recognized as a rare complication of chemotherapy in haematological malignancies. By contrast, the complication is less well known in relationship to chemotherapy for solid malignancies. There are very few examples reported and this paper adds three further cases and reviews the literature. We emphasize that although some cases of neutropenic colitis may be managed medically, full thickness involvement of the bowel wall may lead to perforation and require surgery. The pathogenesis of this progression is discussed and it is concluded that clinical awareness is important in the diagnosis. The signs of peritonitis or septicaemia are indications for excisional surgery with the formation of a temporary ileostomy.

Abstract
A retrospective analysis of 70 patients with primary malignant lymphoma of the thyroid treated at this institute between 1965-1983 has been conducted. The clinicopathological features and prognostic factors have been studied. The mean age was 67.5 years and there was a marked female:male ratio of 8:1. A total of 32 (45.7%) Stage IE and 38 (54.3%) Stage IIE patients were identified. In 64 cases histological material was reviewed and classified employing the Kiel classification. All the tumors were of B cell lineage and the majority were follicle center cell type. A biopsy only was performed in 27 patients, lobectomy in 11 patients, subtotal thyroidectomy in 27 and macroscopic thyroidectomy in 5 patients. All patients were treated with radiotherapy. The overall 5-year survival was 42%, with 63% for Stage IE and 27% for Stage IIE. The corrected overall 5-year survival was 49% with 68% for Stage IE and 36% for Stage IIE. The corresponding overall relapse free survival was 42% with 60% for Stage IE, and 31% for Stage IIE. Factors of prognostic significance for relapse and survival were stage, radiotherapy dose, stridor, retrosternal extension and fixation.

Abstract
Incidence data on a population-based series of bone, soft tissue and visceral sarcomas from the North West of England are presented. The data are derived mainly from a total of 429 cases registered with the North Western Regional Cancer Registry and diagnosed during the period 1982-84, 76% of which were confirmed as sarcomas by a panel of five pathologists. Overall incidence of confirmed sarcomas per million person years was slightly higher in females (26.81) than in males (24.71) but there was no sex difference when 38 non-reviewed cases were taken into consideration (females 29.07, males (28.83). After exclusion of tumours of female genital tract, incidence of soft tissue tumours was very similar in both sexes (females 18.25, males 18.70). Bone tumours were almost twice as frequent in males (6.01) as in females (3.55).

Abstract
The clinical and histopathological characteristics of seven cases of Moderately Differentiated Neuroendocrine Carcinomas (MDNEC) and two cases of Poorly Differentiated Neuroendocrine Carcinomas (PDNEC) have been reviewed. The tumours arose in the supraglottis of predominantly elderly men. Two cases had raised levels of urinary 5-hydroxy-indole-acetic acid at presentation but no case developed the carcinoid syndrome. PDNEC were histologically identical to the oat cell type carcinoma of the bronchus and were associated with an extremely aggressive clinical course with both patients dying of widespread metastases within one month of registration. MDNEC also metastasized frequently with four of seven cases dying with widespread disease. The tumours have previously been reported as not being radiosensitive; however three cases remain free of disease following biopsy and radiotherapy alone. The place of radiotherapy in the management of these tumours is discussed.

Abstract
A total of 468 cases of bone, soft tissue and visceral sarcomas (and certain other tumours) diagnosed during the years 1982-84 in North West England were entered in a study of histopathological peer review, incidence and survival. This paper describes the effects of peer review. Material was reviewed by a panel of five pathologists for 413 of the 450 cases originally registered as sarcomas with the Regional Cancer Registry. The diagnosis of sarcomas was confirmed in 76% cases and and there was agreement on sub-type for 53% cases. Measures of agreement were lowest for the two sub-types most commonly diagnosed i.e. malignant fibrous histiocytoma and leiomyosarcoma. Degree of agreement between individual pathologists and final panel diagnosis was also very variable but never less than 65%. It is concluded that second opinion is essential in cases of presumed sarcomas for studies of incidence and aetiology and to ensure that appropriate treatment is selected.

Abstract
Five diagnostically problematic spindle cell sarcomas showing invasive character, cellular pleomorphism, and high mitotic rate were studied clinically and histopathologically by conventional light microscopy, immunohistochemistry, and transmission electron microscopy. They showed varied clinical courses, with two causing death within 5 years and three showing recurrent and metastatic behavior. All lacked a clearly defined line of differentiation by conventional light microscopy. By immunohistochemistry, all were positive for vimentin and alpha-smooth muscle actin; in addition, one showed focal S-100 protein positivity, and one stained for desmin. All were cytokeratin negative. By electron microscopy, the great majority of spindle cells in all cases showed abundant rough endoplasmic reticulum and fine myofilaments with focal densities; collagen secretion granules were also found in all cases but in fewer cells. The fine structure and immunophenotype were considered consistent with myofibroblastic differentiation; these tumors, therefore, were designated as sarcomas of myofibroblasts or myofibrosarcomas. The suitability of the alternative diagnostic label of myofibroblastic or matrix-secreting variant of leiomyosarcoma is discussed. Comparisons with similar tumors documented in the literature are drawn.

Abstract
In seven of 12 cases of Ber-H2 (Ki-1) positive anaplastic large cell non-Hodgkin's lymphoma (Ki-1 ALCL) disease remained localised to skin, and in five there was extracutaneous spread. Four patients had histological evidence of pre-existing or coexisting mycosis fungoides, and three patients had a long standing history of eczema or ichthyosis. In two cases the presence of a T phenotype was shown in frozen sections, and in a further six cases a T phenotype was firmly established in paraffin wax sections. Four patients died less than one year after presentation (two with disseminated lymphoma; two from other causes); one died at five years with widespread lymphoma and the remaining seven cases were alive one to 14 1/2 years after presentation. Three of the four patients with associated mycosis fungoides had prolonged survival, contrary to the findings of previous reports which suggest secondary Ki-1 ALCL behaves aggressively. The recognition of these tumours is important because of their relatively good prognosis. The diagnosis can be readily substantiated immunohistochemically, using a simple panel of antibodies.

Abstract
The clinical, light microscopic, ultrastructural, immunocytochemical and cytogenetic features of a case of monocytoid B cell lymphoma were investigated. The tumour initially affected the cervical and supraclavicular nodes, but 33 months later affected the left parotid salivary gland. The patient had subclinical Sjögren's syndrome. The neoplastic cells showed characteristic morphological features and had peri- and interfollicular distribution in the node. Immunocytochemically the tumour cells were L26, 4KB5, MB2, CD19, CD20, CD22 and IgM/kappa positive. Prominent plasmablastic plasmacytoid differentiation was present in the recurrent tumour, suggesting an origin from post-follicular B cells. The lymphoma cells showed unusual cytogenetic abnormalities.
