Foamy spheroid bodies (FSBs) are described, as newly identified pathological structures occurring in human brain. FSBs favoured the substantia nigra pars reticulata (SNPR) and/or globus pallidus (GP) in degenerative conditions especially postencephalitic parkinsonism, progressive supranuclear palsy, pallido-nigro-luysial atrophy and multiple system atrophy. No FSBs were observed anywhere in the presence of substantia nigra pars compacta (SNPC) degeneration, such as occurs in idiopathic Parkinson's disease, or luysio-pallidal system degeneration, such as found in dentato-rubro-pallidoluysial atrophy or Joseph's disease. FSBs were also occasionally identified in the substantia nigra (SN) and/or GP of aged persons. In addition to SN and GP lesions, FSBs were seen in diffuse axonal lesions of long fibre tracts (the corpus callosum, the superior cerebellar peduncle) after non-missile head injuries, and in peri-infarct lesions. Under the light microscope, FSBs appear as slightly eosinophilic, foamy and nearly round objects with vague outlines, measuring approximately 10–50 μm in diameter. Some FSBs contain coarse, eosinophilic clusters at their periphery. FSB stained black when stained by the Gallyas silver method. Some FSBs were immunohistochemically positive for synaptophysin and 68 kDa neurofilament. Glial fibrillary acidic proteinpositive fibres were observed alongside and/or inside some FSBs. Electron microscopically, FSBs were found to consist of collections of neuritic debris containing a variety of dense bodies and a small number of both mitochondria and neurofilaments. Some such collections were surrounded by astrocytic processes. These findings strongly suggest that FSBs are collections of small axonal debris destined for removal by astrocytes in due course. A variety of factors (degeneration of the SNPR and/or the GP, injury, infarction, ageing) seemed to be responsible for the histogenesis of FSBs.

A case of Farber disease is reported and the ultrastructural pathology of the disease is reviewed. The present case showed the typical clinical picture of Farber disease. Acid ceramidase deficiency was demonstrated biochemically. Ultrastructural features of one subcutaneous nodule and a skin biopsy are described. Three lysosomal inclusions characterize Farber disease: curvilinear tubular bodies observed mainly in the reticuloendothelial system, “banana bodies” recorded only in the peripheral nervous system and zebra-like bodies which are essentially a neuronal storage. The nature of each is discussed and the skin biopsy is emphasized for its important diagnostic interest.
High endothelial venule and immunocompetent cells in typical medullary carcinoma of the breastTanaka, Hisako; Hori, Masao; Ohki, Takao

The characteristics of immunocompetent cells and their role in killing tumour cells in typical medullary carcinoma of the breast (TMC) have been investigated morphologically. Formation of high endothelial venule (HEV)-like vessels in tumour cell nests, the distribution of macrophages, T-zone histiocytes, T- and B-lymphocytes, the ratios of CD4+/CD8+, and natural killer (NK) or NK-like T-cells were examined in five cases of TMC. These results were compared with controls which consisted of three cases of ductal carcinoma with intense lymphocytic infiltration (control I) and four cases of ductal carcinoma with scanty lymphocytic infiltration (control II). An increased incidence of HEV-like vessels with migration of lymphocytes and a higher number of CD8+lymphocytes with interleukin-2-receptor expression, as well as numerous CD57 cells, were noted in the tumour nests of TMC as compared with those of control groups. Furthermore, large granular lymphocytes, large lymphocytes invaginating tumour cells and necrotic tumour cells were observed electron microscopically. These findings indicate that infiltrating lymphocytes in TMC are activated and become effector cells that can kill the tumour cells by mechanisms similar to those of NK cells. The activities of immunocompetent cells in TMC appear to contribute to a favourable prognosis in TMC of the breast.

A monoclonal antibody, F11C, was raised against rat colon cancer cells. Its immunoreactivity on normal human and rat gut as well as human and rat colonic tumours was studied by the avidin-biotin-peroxidase complex technique. In both normal rat and human gastrointestinal tract, F11C stained surface epithelial cells from the fundus to distal colon, mainly as supranuclear vesicles. These vesicles appeared to be part of the Golgi apparatus on electron microscopy with immunogold labelling. Twenty primary rat colon tumours and 28 of 43 human colon tumours were also stained, with a heterogeneous pattern but much more strongly than the normal colonic mucosa. Biochemical purification suggested that in rat tumours F11C epitope was carried by a high molecular weight glycoprotein. Absorption experiments with synthetic oligosaccharides showed that F11C monoclonal antibody reacted with blood group A-related oligosaccharides. Nevertheless, F11C reactivity on human tissues was not related to the individual ABO or Lewis phenotype.
Factor-XIIIa-expressing dermal dendrocytes in Kaposi's sarcomaKanitakis, Jean; Roca-Miralles, Mercedes
doi: 10.1007/BF01600275pmid: 1348156
The histogenetic origin of Kaposi's sarcoma is a matter of controversy, with recent reports claiming it to derive from the factor-XIIIa-positive dermal dendrocyte rather than endothelial cells. We investigated the potential role of factor-XIIIa-positive dermal dendrocytes in the genesis of both classical (endemic) and immunosuppression-associated Kaposi's sarcoma. Thirteen cases of classical and 16 cases of immunosuppression (mostly AIDS)-associated Kaposi's sarcoma were immunostained with antibodies to factor XIIa and to the blood-group antigen H, recognizing endothelial cells. Factor-XIIIa-positive cells were consistently antigen-H-negative and represented only a small percentage (usually less than 10%) of the proliferative cells. Their relative density tended to be decreased in immunosuppression-associated Kaposi's sarcoma when compared with that of the classical form. These results do not support the view that dermal dendrocytes may be the cells of origin of Kaposi's sarcoma; conversely, their decreased density in cases of immunosuppression-associated Kaposi's sarcoma could be related to immunosuppression and may account for more rapid tumour growth.
Immunoglobulin idiotype expression in reactive lymphoid tissues and B-cell lymphomasShiota, Mami; Kitamura, Kiyoshi; Noda, Miyako; Kawanishi, Yoshikazu; Hart, Sarah; Miller, Richard; Mori, Shigeo

In an investigation of the immunoglobulin idiotypic expression of non-tumour and neoplastic B lymphocytes in situ, fresh-frozen specimens of reactive tonsils, lymph nodes and B-cell malignant lymphomas (B-MLs) from Japanese patients were studied immuno-histochemically with 39 different anti-idiotype antibodies. In reactive lymphoid tissues, while idiotype-bearing cells were largely distributed sparsely in follicles and perifollicular areas, some were heavily crowded in particular germinal centres (GCs), suggesting the presence of oligoclonal proliferations of B-cells in GCs. Forty-eight out of 100 B-MLs reacted with anti-idiotype antibodies. This proportion was significantly higher than those reported in Western cases (27–36%), indicating that Japanese B-MLs share public idiotypes much frequently than western cases. The idiotypes demonstrated in these lymphomas, in contrast to those not expressed in any B-ML, were found much commonly in non-tumour lymphocytes, suggesting that such public idiotypes as were common in B-MLs were frequently shared by normal B-lymphocytes.
Differential diagnostic patterns of lung neuroendocrine tumoursBonato, Marzia; Cerati, Michele; Pagani, Alberto; Papotti, Mauro; Bosi, Federica; Bussolati, Gianni; Capella, Carlo

A series of 3 tumourlets (TLs), 81 typical carcinoids (TCs), 14 atypical carcinoids (ACs) (well-differentiated neuroendocrine carcinomas, WDNCs) and 24 small cell-intermediate cell carcinomas (SCC-ICCs) of the lung were studied. HIstopatological features were correlated with amine and peptide hormone immunoreactivity and with clinical data. All types of tumours expressed general neuroendocrine (NE) markers: Grimelius positivity and chromogranins were detected more frequently in well-differentiated (TLs, TCs) than in less well differentiated tumours [ACs (WDNCs) and SCCICCs] whereas neuron specific enolase (NSE) was prominent in the latter tumours. TLs and peripheral TCs were benign, often showing a paraganglioid pattern and frequently expressing gastrin-releasing peptide (GRP), which is present in the peripheral airways of normal lung. Central TCs were associated with lymph node metastases in 8.5% of the cases, frequently had a trabecular architecture, often associated with human milk fat globule 2 (HMFG2)-positive acinar and rosette-like structures, and were mainly immunostained for theα-subunit of human chorionic gonadotrophin (α-hCG) and serotonin. ACs (WDNCs) were associated with intrathoracic and/or extrathoracic metastases in 57.1% of the cases with a mortality rate of 35.7%. Their histological and cytological features were intermediate between those of TCs and SCC-ICCs. ACs (WDNCs) expressed serotonin andα-hCG less frequently than TCs. All SCC-ICCs were surgically treated and displayed a mortality rate of 91.6% with a mean survival of 10.2 months after operation. These tumours were characterized by high expression of HMFG2 and NSE, while the expression of both orthotopic (serotonin, GRP) and ectopic (ACTH) specific NE substances was very low. Since all TCs (either central or peripheral) had a favourable outcome, while about 36% of ACs (WDNCs) were fatal, the latter seem more appropriately designated “well-differentiated NE carcinomas’. The differential diagnosis between different NE tumours of the lung is important and is mainly based on morphology. Both panendocrine and specific immunohistochemical markers are helpful in distinguishing the less aggressive, mostly benign varieties from the more malignant varieties.

The use of chelating resin in a simple, rapid and efficient pre-treatment protocol to process formalin-fixed, paraffin-embedded specimens for the polymerase chain reaction (PCR) is described and compared to other pre-treatment techniques. With this modified PCR protocol, a variety of human autopsy and biopsy specimens were investigated for presence of DNA of human papil-lomaviruses, cytomegalovirus or Epstein-Barr virus. These viruses were detected in a productive or non-/low-productive state. Amplimers generated ranged from 88 to 450 base pairs length. Under the specified technical conditions, a considerable range of DNA molecules can be amplified from paraffin-embedded material, some older than 10 years.
Expression of adult T-cell leukaemia-derived factor, a human thioredoxin homologue, in the human ovary throughout the menstrual cycleIwai, Toshiko; Fujii, Shingo; Nanbu, Yoshihiko; Nonogaki, Hirofumi; Konishi, Ikuo; Mori, Takahide; Masutani, Hiroshi; Yodoi, Junji

An immunohistochemical study of the expression of adult T-cell leukaemia-derived factor (ADF), a human thioredoxin homologue, was performed in the normal human ovary throughout the menstrual cycle. Primordial follicles were negative for ADF. Both granulosa cells and theca interna cells at the stages of preantral and antral follicles contained ADF. The staining intensity of these cells was very strong in the preovulatory dominant follicle. After ovulation, both granulo-lutein and theca-lutein cells were positive for ADF. During pregnancy, the theca-lutein cells revealed very intense ADF staining. The theca interna cells of the atretic follicles showed ADF staining, while the granulosa cells of such follicles did not. These results suggest that ADF localizes in the ovarian steroidogenic cells which have the binding sites of either luteinizing hormone or folliclestimulating hormone, and that ADF expression is closely associated with the activity of the ovarian steroidogenic cells.
Granular cell tumour of the breastDamiani, Stefania; Koerner, Frederick; Dickersin, G.; Cook, Martin; Eusebi, Vincenzo

Eight cases of benign granular cell tumour of the breast are reported. Seven patients were women and one was male. The age at the time of the excision ranged from 17 to 73 (average 40.1) years. All tumours were positive for S-100 protein and negative for keratin, myoglobin and gross cystic disease fluid protein. In two cases ultrastructural studies revealed findings identical to those in the previously reported cases of granular cell tumours. None of these cases were diagnosed preoperatively. In six cases the clinical and mammographic findings, and in one case the frozen section, led to an erroneous diagnosis of malignancy. The clinico-pathological features of the cases are delineated in order to draw attention to a benign condition which closely simulates malignancy.
