Abstract
In the framework of intense research about high-entropy materials and their applications in energy-oriented technologies, in the present work, we discuss the potential applicability of selected oxides and of the alloys they form at different concentrations for daytime radiative cooling implementation. In particular, by combining density functional theory and the finite difference method, we provide an unbiased, scattering-free description of structural, electronic, and dynamic features of the best candidates, showing the required strong radiative properties for passive cooling while offering the benefits of affordability and compatibility with commercial coating fabrication processes.

Abstract
The novel ZrIV-based perfluorinated metal-organic framework (PF-MOF) [Zr6O4(OH)4(TFS)6] (ZrTFS) was prepared under solvent-free conditions using the commercially available tetrafluorosuccinic acid (H2TFS) as a bridging ditopic linker. Since H2TFS can be seen as the fully aliphatic and perfluorinated C4 analogue of fumaric acid, ZrTFS was found to be isoreticular to zirconium fumarate (MOF-801). The structure of ZrTFS was solved and refined from X-ray powder diffraction data. Despite this analogy, the gas adsorption capacity of ZrTFS is much lower than that of MOF-801; in the former, the presence of bulky fluorine atoms causes a considerable window size reduction. To have PF-MOFs with more accessible porosity, postsynthetic exchange (PSE) reactions on (defective) MOF-801 suspended in H2TFS aqueous solutions were carried out. Despite the different H2TFS concentrations used in the PSE process, the exchanges yielded two mixed-linker materials of similar minimal formulae [Zr6O4(μ3-OH)4(μ1-OH)2.08(H2O)2.08(FUM)4.04(HTFS)1.84] (PF-MOF1) and [Zr6O4(μ3-OH)4(μ1-OH)1.83(H2O)1.83(FUM)4.04(HTFS)2.09] (PF-MOF2) (FUM2- = fumarate), where the perfluorinated linker was found to fully replace the capping acetate in the defective sites of pristine MOF-801. CO2 and N2 adsorption isotherms collected on all samples reveal that both CO2 thermodynamic affinity (isosteric heat of adsorption at zero coverage, Qst) and CO2/N2 adsorption selectivity increase with the amount of incorporated TFS2-, reaching the maximum values of 30 kJ mol-1 and 41 (IAST), respectively, in PF-MOF2. This confirms the beneficial effect coming from the introduction of fluorinated linkers in MOFs on their CO2 adsorption ability. Finally, solid-state density functional theory calculations were carried out to cast light on the structural features and on the thermodynamics of CO2 adsorption in MOF-801 and ZrTFS. Due to the difficulties in modeling a defective MOF, an intermediate structure containing both linkers in the framework was also designed. In this structure, the preferential CO2 adsorption site is the tetrahedral pore in the "UiO-66-like" structure. The extra energy stabilization stems from a hydrogen bond interaction between CO2 and a hydroxyl group on the inorganic cluster.

Abstract
We report a novel synthetic procedure for the high-yield synthesis of metal-organic frameworks (MOFs) with fcu topology with a UiO-66-like structure starting from a range of commercial ZrIV precursors and various substituted dicarboxylic linkers. The syntheses are carried out by grinding in a ball mill the starting reagents, namely, Zr salts and the dicarboxylic linkers, in the presence of a small amount of acetic acid and water (1 mL total volume for 1 mmol of each reagent), followed by incubation at either room temperature or 120 °C. Such a simple "shake 'n bake" procedure, inspired by the solid-state reaction of inorganic materials, such as oxides, avoids the use of large amounts of solvents generally used for the syntheses of Zr-MOF. Acidity of the linkers and the amount of water are found to be crucial factors in affording materials of quality comparable to that of products obtained under solvo- or hydrothermal conditions.

Abstract
Thirty-four cases of adenoid cystic carcinoma (ACC) of the major and minor salivary glands of the oral cavity, treated by wide surgical excision, were studied. The relationship between prognosis of the neoplasm and various morphologic factors were evaluated. Among the morphologic parameters previously studied, which according to various authors may be linked to the evolution of this tumor, we confirmed correlations for both histologic patterns and perineural invasion. In addition, the authors propose neoplastic growth type as a new parameter prognostically significant in ACC. In fact, none of the patients with the pushing type growth pattern died during the study period (p = 0.007). These same patients presented disease-free periods (mean 56 months, median 58 months) significantly longer than those with the infiltrating type growth pattern (mean 28 months, median 24 months).

Abstract
Background Intestinal-type adenocarcinoma (ITAC) of the nose and paranasal sinuses is a relatively rare tumor. It commonly affects subjects exposed to wood or leather dust. Methods The authors present the clinicopathologic findings of 18 cases of sinonasal ITACs and review the proposed histologic classifications. Results All patients, except one, were males; mean age was 60 years (range, 41-79); in 9 cases an occupational exposure to wood or leather dust was found. Common presenting symptoms were epistaxis, nasal obstruction and rhinorrhea. Histologically, tumors were divided into four groups: well-differentiated (G1) ITACs = 3 cases; moderately differentiated (G2) ITACs = 8 cases; poorly differentiated (G3) ITACs = 2 cases; mucinous (M) ITACs = 5 cases. Immunocytochemically, 16/17 cases were positive for carcinoembryonal antigen, 1/17 for somatostatin, and 0/16 cases for gastrin. Conclusions Sinonasal ITACs are aggressive tumors, often diagnosed in a relatively advanced stage. Owing the close similarity of the microscopic aspects, a histologic classification of ITACs analogous to that of colonic adenocarcinomas is proposed.

Abstract
An intraoral adenocarcinoma showing syringomatous features is reported in a woman aged 71. The tumor, which appeared to arise in minor salivary glands, ulcerated the overlying epithelium. Histologically, it was composed of dilated ductal structures and, in deeper parts, of tumor nests, elongated cords and small ducts containing small lumina. In wide areas, neoplastic ducts were lined by flattened cells, resembling syringoma of the skin. Other ductal structures were lined by atypical columnar or squamous epithelium. Solid squamous islands and superficial small horny cysts were also observed. Salivary glands tumors with syringomatous features have rarely been reported. They probably represent a rare variant of salivary adenocarcinoma.

Abstract
A case is presented of a male patient affected by a giant cell lesion of the jaw, which had two recurrences in 8 years. Histologically, the lesion appeared to be composed of giant cells and mononuclear cells. Histoenzymatic study demonstrated acid phosphatase in both types of cells, and beta-glucuronidase in giant cells only. In some nuclei of giant cells, ultrastructural investigation showed filaments or microtubular structures of variable length, with irregular transverse periodicity, in addition to other expected findings. These characteristic features, found in giant cells of some giant cell tumors of the long bones, have never before been reported in a giant cell lesion of the jaw. The results are considered in order to assess the diagnosis, and the pathologic profiles of giant cell reparative granuloma, and of giant cell tumor are critically discussed.

Abstract
The patient-oriented measures, represented by self-administered questionnaire, have become an important aspect of clinical outcome assessment. To be used with different language groups and in different countries, questionnaires must be translated and adapted to new cultural characteristics and then validated by a widely accepted process to evaluate reliability and validity, fundamental characteristic for each measure. The aim of the study is to perform the cross-cultural adaptation and to assess the Italian version instrument reliability and validity. The study design is a cross-cultural adaptation and cross-sectional study of a sample of patients affected by shoulder disorder with a subsample followed prospectively for retest reliability. The American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form was culturally adapted for Italian-speaking people, following the simplified Guillemin criteria. Reliability and validity were assessed in a cross-sectional study of 50 consecutive patients affected by shoulder disorder. A sub-sample of 20 patients was followed prospectively for retest reliability. The results were compared with other validated patient-oriented measures. The ASES scales showed a high correlation with other patient-oriented measures, as hypothesized, and it also showed good values with regard to reproducibility, consistency and validity, to the original versions published in English. These findings suggest that the evaluation capacities of the Italian version of ASES are equivalent to those of English language version.

Abstract
CONTEXT Several aspects of sweat gland carcinomas (incidence, classification, diagnosis, and behavior) have not been definitively clarified and need to be studied further. OBJECTIVE The clinicopathologic findings of a large series of sweat gland carcinomas, collected during a period of 15 years, are presented. METHODS Sixty sweat gland carcinomas (41 porocarcinomas, 3 syringomatous carcinomas, 8 ductal carcinomas, 5 adenoid cystic carcinomas, and 3 mucinous carcinomas) were analyzed histologically and immunohistochemically. RESULTS Porocarcinomas were composed of eosinophilic and clear atypical cells arranged in solid-cystic lobular masses. These tumors were divided into 2 subgroups: horizontal porocarcinomas, showing a prominent intraepidermal component, and nodular porocarcinomas, which demonstrated predominant nodular growth. Syringomatous carcinomas presented keratinizing and nonkeratinizing cysts, dilated tubules (sometimes with a "tadpole" appearance), small neoplastic ducts, solid islands, and cellular cords. Ductal carcinomas were characterized by a prominent formation of tubules, solid islands, and cellular cords. Adenoid cystic carcinomas presented a characteristic pattern, showing basaloid monomorphous cells with moderately atypical nuclei, arranged in cribriform or solid islands and in tubular structures. Mucinous carcinomas were composed of moderately atypical cells with eosinophilic vacuolated cytoplasm, forming solid and cystic islands floating in large mucin pools. Immunohistochemically, cytokeratin was found in neoplastic cells in all cases, carcinoembryonic antigen was detected in 73% of cases, and actin-positive (myoepithelial) cells were not found. CONCLUSIONS Although numerous studies have been published in recent years, the histologic features, histogenesis, and classification of sweat gland carcinomas still remain controversial and need to be clarified by further studies.

Abstract
OBJECTIVE This study investigates the distribution of the alpha chain of the integrin family of extracellular matrix receptors in a series of adenomas and carcinomas of salivary gland origin to determine if the malignant phenotype is associated with modification of the expression of these receptors. STUDY DESIGN Cryostat sections of 36 tumor specimens were stained by a standard streptavidin-biotin-peroxidase technique using primary monoclonal antibodies against alpha 1-6 and alpha v integrin chains. The immunohistochemical reaction was scored using a three-point scale and the results were analyzed using Fisher's exact test. RESULTS In salivary adenomas, alpha 2, alpha 3, alpha 4, alpha 6, and alpha v chains were widely expressed in most of the cases studied. The alpha 1 subunit was prominently expressed by the epithelial cells of Warthin's tumor, whereas a minority of pleomorphic adenomas showed immunoreactivity for this antigen. We observed alpha 5 subunit expression only in the mesenchymal-like component of pleomorphic adenomas. In salivary carcinomas, integrin alpha chain expression was heterogeneous, varying greatly between different histotypes and within the same histotype. The distribution of the antigens was similar to that of adenomas, except for the alpha 6 chain, which localized not only at the interface between cell and matrix, but also at sites of cell-cell contact. When the immunohistochemical levels of integrin alpha chain expression were compared in adenomas and carcinomas, expression significantly decreased for the alpha 6 and alpha v chains (p = 0.0007; p = 0.002, respectively). CONCLUSIONS Loss of alpha 6 and alpha v integrin subunits occurring in salivary gland carcinomas could modify the adhesive properties of malignant cells, contributing to the invasive potential of these tumors.

Abstract
The infiltration of the epidermis by malignant melanocytes is a characteristic phenomenon of cutaneous melanoma. A series of consecutive unselected cutaneous melanomas was histologically reviewed in order to study the frequency and the characters of epidermal infiltration. Such a feature was found in 86% of tumors (93% in superficial spreading melanomas); it was extensive in 65% of cases, focal in 35%; topographically, it was central and peripheral in 67%, peripheral in 30%, central in 3%. Results show that epidermal infiltration, albeit inconstant, is a useful feature in the histological diagnosis of melanoma (especially in SSM), provided that it is distinguished from pseudoinfiltration, a histologically similar, but intrinsecally different, feature observed in some benign melanocytic lesions.

Abstract
Mixed tumors of the skin are characterized by a proliferation of epithelial cells embedded in a mesenchymal matrix with a wide spectrum of histologic appearances. The characterization of the extracellular matrix components of mixed tumors of the skin has so far received little attention. We performed an immunohistochemical study of type IV collagen, laminin, fibronectin, and tenascin distribution in a series of 10 mixed tumors of the skin. Laminin localized at the basement membrane around solid epithelial nests and tubulo-alveolar structures, whereas type IV collagen, fibronectin, and tenascin were also expressed in the myxoid stroma. Tenascin and fibronectin localized in the chondroid matrix. The extracellular matrix components were prominently expressed in mixed tumors of the skin, suggesting that they could play an important role in the formation and organization of myxoid and chondroid matrices and in the epithelial-mesenchymal interactions of these tumors.

Abstract
The localization of the integrin subunits alpha 2, alpha 5, alpha 6 was studied immunohistochemically in samples of normal salivary gland and in a series of 8 pleomorphic adenomas, 5 Warthin's tumors, and 2 basal cell adenomas. In normal salivary tissue, acinar and ductal cells expressed alpha 2 and alpha 6 chains at the basal cell pole facing the basement membrane. alpha 2 also localized at sites of cell-cell contact. No staining of the epithelial component was seen with alpha 5. The polarized expression of alpha 2 and alpha 6 subunits was retained in salivary adenomas. These subunits were present at the basal cell pole of solid nests, tubules and ducts of pleomorphic adenomas, as well as of the basal layer of the epithelium of Warthin's tumor, and of the trabecular structures of basal cell adenomas. The alpha 5 subunit was consistently expressed only by cells embedded in the myxoid or chondroid matrix of pleomorphic adenomas. We conclude that the pattern of a integrin subunit expression in salivary adenomas may be related to the "epithelial" or "mesenchymal" phenotype of the neoplastic cells.

Abstract
The histological intraepidermal characteristics considered to be specific to dysplastic nevi (radial extension, lentiginous and disordered nest proliferations, cytological atypia or dyskaryosis) were investigated in a series of 114 acquired nevi showing various clinical appearances in an attempt to establish whether dysplastic nevi can be considered a homogeneous class of lesions, clearly distinct from common nevi. On the basis of the distribution of investigated architectural features, found singly or variously associated, the examined lesions were divided into 5 groups, showing an increasing incidence of dyskaryosis. Results suggest that acquired nevi, rather than two distinct classes (common and dysplastic nevi), form a histological spectrum of lesions, within which the border between lesions implying and not implying an increased melanoma risk cannot be objectively fixed.

Abstract
The presence of Epstein-Barr virus (EBV) DNA-sequences in specimens of Warthin's tumor in the parotid gland was studied. Using an in situ hybridization technique, EBV genome was detected in distinct cell types in routinely processed tissues. The authors' results indicated that EBV is frequently present in the cytoplasm (possibly because of a chronic, productive infection) of neoplastic cells of multiple/bilateral Warthin's tumor (MBWT) (86.7%), and only occasionally of solitary Warthin's tumor (SWT) (16.7%). In addition, EBV genome has often been documented in the cytoplasm of ductal cells (75% of MBWT and 33.3% of SWT), and occasionally of acinar cells (16.7% of both MBWT and SWT) of residual normal salivary gland tissue surrounding both MBWT and SWT. The almost constant presence of EBV DNA in tumor cells of MBWT, as opposed to the occasional finding in SWT, suggested a strong association between infection of cells with this virus and the development of multiple/bilateral lesions. The positivity of ductal epithelium supported speculations about the role of ductal cells as a histogenetic precursor of the tumor. This was the first report on the detection of EBV genome in Warthin's tumor.

Abstract
Seven cases of sweat-gland carcinomas showing eccrine ductal differentiation (ductal carcinomas) are presented. The tumors had a variable histological appearance, but were basically characterized by the following histological elements: (a) tubular structures, sometimes cystic or having a "tadpole" appearance; (b) solid islands of squamous, basaloid, or clear cells; (c) periodic acid-Schiff-positive endoluminal and/or intracellular material; and (d) infiltrating growth. Immunocytochemically, tumor cells were positive for keratin and negative for actin. Endoluminal material contained carcinoembryonic antigen in five of seven cases. Although it is not yet clear whether carcinomas exhibiting eccrine ductal differentiation may represent a specific histotype or a group encompassing several distinct clinicopathological entities, the histological analysis of the cases suggested that the wide spectrum of their histological appearances may be due to variable grades of differentiation.

Abstract
Ten (dermato)pathologists studied 50 cutaneous melanocytic lesions including common naevocellular naevi, dysplastic naevi (DN), melanomas in situ and invasive primary melanomas, with emphasis on the histological criteria of DN. Using a standardised form, 20 defined histopathological features were scored (semi)quantitatively. Concordance of diagnosis, efficacy and reproducibility of features were investigated. DN were distinguished well from the other entities (mean Po 0.87). Agreement on the degree of atypia of DN was low. The reproducibility of the scoring was best for the following features: irregular nests, lymphohistiocytic infiltrate, marked junctional proliferation and large nuclei. The overall values of these features to discriminate between DN and non-DN were better than for the other features studied. Using the presence of at least three of the four features as a condition for the diagnosis of DN, values for sensitivity, specificity and positive and negative predictive values were 0.86, 0.91, 0.96 and 0.73, respectively. On the basis of the results these features seem best suited as histological criteria for the diagnosis of DN.

Abstract
The 3H-thymidine labelling (LI) and mitotic (MI) indexes were calculated in 29 cutaneous melanocytic lesions: 6 common nevi (CN), 11 dysplastic nevi, subclassified as nevi with architectural atypia (NAA = 4) and nevi with cyto-architectural atypia (NCAA = 7), 2 melanomas in situ (MIS), 4 invasive superficial spreading melanomas (IM) and 6 metastatic melanomas (MM). The LI mean values resulted to be: CN = 0.23%, NAA = 0.98%, NCAA = 1.79%, MIS = 5.75%, IM = 5.16%, MM = 3.80%. In CN, NAA, NCAA and MIS, these values were calculated at epidermal level; in IM and MM at dermal level. At dermal level, the LI mean values of CN, NAA and NCAA were: 0.20%, 0.20%, 0.23% respectively. The MI mean value was close to 0 in CN, NAA, NCAA, MIS; 0.18% in IM, 0.16% in MM. Confirming a low proliferative activity in CN and a high activity in melanomas (MIS, IM, MM), the results showed that dysplastic nevi (NAA, NCAA) had a proliferative activity intermediate between common nevi and melanomas. The lesions with melanocytic atypia (NCAA) resulted to have a higher proliferative activity than those without this histological feature (NAA).

Abstract
A series of 233 consecutive primary cutaneous melanomas was histologically and clinically studied. Histologically, 53 melanomas (22.7%) were associated with naevus cells. Such a high degree of association suggests that melanocytic naevus may be a precursor of a large number of melanomas. Analysing the cases according to Clark's levels and Breslow's index, a decrease in the naevus-melanoma association was seen with tumour progression, suggesting that advanced tumours may overgrow pre-existing nevus cells, appearing as de novo melanomas. The comparison between histological and clinical data suggest some interpretations of the natural history of melanoma.

Abstract
Intratumoral and peritumoral infiltration of T-zone histiocytes, mainly of mature Langerhans cells, was investigated in 88 patients with squamous cell carcinoma of the larynx by immunohistochemical methods using polyclonal antibodies against S100 protein and lysozyme. Granulocytic and lymphoid inflammatory infiltration and its relationship to the presence of Langerhans cells were also evaluated. Langerhans cells were present within the cancer tissues and showed a relationship with lymphoid infiltrate. No significant correlation was present among the density of Langerhans cells and the site of neoplastic growth (supraglottic or subglottic), granulocytic inflammatory infiltration, histological tumor grade, or clinical stage. Patients with high or intermediate density of Langerhans cells survived longer than those with low density (mean survival, 61%, 62%, and 0%, respectively). The number of Langerhans cells was relevant in patients with evident infiltration of lymphocytes and plasma cells, according to their ability to present antigens to sensitized T cells. Our results indicate that the presence of high or intermediate density of Langerhans cells and of marked lymphoid inflammation may be considered favorable prognostic factors for patients with squamous cell carcinoma of the larynx.

Abstract
Two cell kinetic parameters, the 3H-thymidine labeling index (TLI) and the mitotic index (MI), were studied in vitro on fragments of squamous cell carcinoma tissue of the larynx. They were evaluated to identify those elements able to characterize the growth of these solid tumors. The values of these parameters were analyzed as a function of the clinical stage and the involvement of the regional lymph nodes. Results showed a statistically significant increase in the TLI from stage T1 to T3. No statistically significant differences in the TLI values were observed between the patients with positive and negative lymph nodes.

Abstract
Histopathologic parameters in predicting lymph node metastasis of supraglottic laryngeal carcinoma. A systematic clinical-pathological study was performed on fifty-three resected cases of supraglottic laryngeal squamous cell carcinoma, followed up for at least 5 years. The aim of the research was to evaluate histopathologic parameters in predicting lymph node metastasis (N+) as expression of biological malignancy of the neoplasm. The following neoplastic microscopical features were studied: histopathologic and cytologic grading, pattern of growth, peritumoral inflammatory infiltrate, stromal reaction, tumoral necrosis. The results are as follows: stromal reaction and cytologic grading are not useful to identify N+ and N- cases. Cases with high and low degree of differentiation (Broder's grading) are significantly correlated respectively to low (14.3%) and high (70%) incidence of lymph node metastasis (p less than 0.03). A clear correlation is present between the pattern of growth "pushing" and lacking of node metastasis (84.6%). A favorable prognosis significance seems to be linked with the presence of peritumoral lymphoplasmocytic infiltrate, which results to be a marker of cases in which lymph node metastasis incidence is very low (5.5%; p less than 0.001). On the contrary lymph node metastasis incidence increase when tumoral necrosis is present (76.5%; p less than 0.001).

Abstract
We report a case of cutaneous myxoid melanoma in a 61-year-old man. Histologically, the tumor, which showed an adjacent intraepidermal proliferation of atypical melanocytes, was composed of spindle-shaped and epithelioid cells with atypical nuclei, arranged in lobules and embedded in a prominent myxoid stroma. Primary cutaneous myxoid melanoma is rare: we found only one other example in the literature.

Abstract
Fifty cutaneous pigmented lesions characterized by an intraepidermal proliferation of atypical melanocytes were reviewed. Several histological parameters (position of melanocytes in the epidermis, nuclear melanocytic atypia, presence or absence of pagetoid melanocytes, nucleoli, and others) were evaluated. On the basis of the results, the investigated cases were classified into three groups. In group 1, pagetoid melanocytes were present, melanocytic atypia was severe and continuous, all epidermal layers were involved by melanocytic proliferation, and a pattern of epidermal infiltration was recognized. In group 2, pagetoid melanocytes were absent, melanocytic atypia was mild-moderate and discontinuous, the lower epidermis only was involved by melanocytic proliferation, and a pattern of epidermal pseudoinfiltration was recognized. Group 3 cases were in an intermediate area between the two major groups. The results showed that intraepidermal proliferations of atypical melanocytes lie on one line, in which groups 1 and 2 account for the extremes.

Abstract
Histological analysis of intraepidermal melanocytic proliferation in the peripheral areas of superficial spreading melanoma. The intraepidermal melanocytic proliferation in the areas adjacent to the invasive component of 100 superficial spreading melanomas of the skin (levels III and IV) was studied. Three patterns were identified: 1) melanoma in situ type (MIS); 2) melanocytic dysplasia type (DYS); 3) normal skin or increased number of typical melanocytes (0). The different distribution of these patterns in the areas adjacent to the invasive melanoma led to a histological classification of the tumors into 4 topographical models. Two models showed MIS areas and contiguous normal skin (A1, A2); two models showed MIS areas adjacent to DYS areas, that in turn were contiguous to normal skin (B1, B2). In all cases, however, in centrifugal sense, more severe alterations preceded less severe ones. These observations suggest that superficial spreading melanoma grows horizontally by induction of neighbour cells (neoplastic recruitment). The neoplastic transformation seems to progress in two ways: directly to melanoma in situ or through an intermediate phase (melanocytic dysplasia).

Abstract
Adenoid cystic carcinoma (ACC) of salivary gland origin shows histologic patterns (tubular, cribriform, solid) that have been correlated with the clinical course of the disease. Recognition of tubular pattern is generally easy. Discrimination between cribriform and solid types leaves some margin for the pathologist's subjective interpretation because it is essentially based on the amount of gland-like spaces, containing mucinous or hyalinized material, which are present in neoplastic nests. To overcome this problem and with the aim of identifying a more objective basis for prognostic evaluation of cribriform and solid ACC, the authors counted the number of gland-like spaces per square millimeter of tumor, excluding supporting stroma and small areas with the tubular pattern, in a group of tumors similar with regard to therapy, stage of disease, and microscopic evidence of tumor-free surgical margins. According to the authors' data, the number of gland-like spaces per square millimeter of tumor appears to be a reliable and objective measure for prognostic evaluation of cribriform and solid pattern ACC; in particular, the greater the number of gland-like spaces per square millimeter of tumor, the longer the survival of the patient.

Abstract
Three cases of multicentric reticulohistiocytosis showing typical clinical, histologic, and ultrastructural findings are reported. In one, gastric cancer occurred; in the other two cases, severe polyarthritis was the only detectable internal involvement. The serine proteinases, urokinase and tissue-type plasminogen activator, were evaluated both with the autohistographic technique and spectrophotometric assay in lesional skin and synovia. Urokinase levels appeared grossly increased in the lesional synovia and moderately increased in the lesional skin. We suggest that urokinase, presumably released by the activated proliferating histiocytes, may play a major role in the extracellular matrix degradation leading to erosion of cartilage and adjacent bone in multicentric reticulohistiocytosis.

Abstract
Nuclei of melanocytes in 10 lentigines simplices, 10 junctional, 10 compound and 10 intradermal acquired melanocytic nevi were morphometrically evaluated, at three different skin levels: epidermis, papillary and reticular dermis. The considered parameters were: area, perimeter, form Ar, and form Ell. Mean values of nuclear area and form Ell demonstrated a progressive increase from lentigines to junctional to compound to dermal nevi. This trend was also observed for each considered level. In compound nevi mean values of nuclear area showed an increase from the epidermis to the papillary dermis. In compound and intradermal nevi they showed a decrease from the papillary to the reticular dermis. Mean values of nuclear form Ell presented a continuous increase from the epidermis to the papillary and reticular dermis. Our study shows that, in the evolution of the considered melanocytic lesions (from lentigo to dermal nevi), the nuclei of melanocytes become larger and rounder. In compound nevi, epidermal nuclei were smaller and more elongated than those of the papillary dermis. In compound and intradermal nevi, superficial dermal nuclei appeared larger but less round than the deep ones. These peculiar findings have been generally referred to as a melanocytic maturation process. They are also probably due to other factors, perhaps local factors, because a similar trend is observed in some malignant melanomas.

Abstract
The phenotypic profile of atypical cells from a patient with cutaneous multilobated T-cell lymphoma was investigated using a multiparameter approach including evaluation of membrane markers, cytochemistry, and functional activity. Retroviral sequence restriction analysis was also used to investigate the presence of human T-cell leukaemia/lymphoma virus type I (HTLV-I) in atypical cells infiltrating the skin and in otherwise normal peripheral blood lymphocytes. The atypical cells appeared to belong to the T-lineage demonstrating OKT11 positivity, E-rosette formation, tartrate-sensitive acid phosphatase and beta-glucuronidase activity, and consistent negativity for cytoplasmic and/or surface monoclonal immunoglobulins. However, they failed to stain for other T-lymphocyte-associated antigens, such as those defined by OKT3, OKT4, OKT6, OKT8, OKT9, OKT10, Leu-2a and Leu-3a monoclonal antibodies, and did not express a definite alpha-naphthyl-acetate esterase pattern. Additional studies including phagocytosis tests and a series of monoclonal antibodies against phagocytic and natural killer cell associated antigens were all negative. No HTLV-I related sequences were found in either the cells infiltrating the skin or in circulating lymphocytes. To our knowledge, in previously reported cases of cutaneous multilobated cell lymphoma a clear T-lymphocyte phenotypic profile was demonstrated. Our present data indicate that this is not always necessarily the case. The peculiar phenotype we found might represent a transitional state between different T-cell subsets or an as yet unrecognized phenotype of a neoplastic T-lymphocyte which lacks a normal counterpart.

Abstract
Sixty-seven patients with nodular sclerosis (Hodgkin's disease stages I and II) have been subclassified according to the cellular composition and the amount of fibrosis. Predominance of mature lymphocytes and rarity of Reed Sternberg cells were associated with less extensive disease at presentation and more favourable outcome. A less definite correlation to the amount of fibrosis was found.
