Abstract
Background Lichen planus is a common skin disorder of unknown etiology. Most cases are idiopathic, but substances such as gold, antimalarials, penicillamine, thiazide diuretics, β-blockers, arsenic and nonsteroidal anti-inflammatory drugs have been implicated as trigger factors. Case Presentation We report the case of a lichenoid eruption in a male drug addict who administered oral heroin (diamorphine) intravenously. Diamorphine was stopped immediately. Following topical steroids, phototherapy and oral acitretin, the lesions gradually disappeared. A lymphocyte transformation test was negative for pure morphine and codeine. Discussion A coincidental association between the intravenous application of orally formulated semisynthetic heroin and the lichenoid eruption cannot be completely ruled out. However, the diagnosis of a lichenoid drug eruption is favoured over idiopathic lichen planus because of the clear chronological correlation between drug use and appearance as well as drug withdrawal and disappearance of the skin lesions, and because of a flare-up following repeated intravenous application of diamorphine.

Abstract
Depending on the location, dermatoses can produce blemishes that severely impair quality of life and require highly effective treatment that is otherwise used for extensive skin involvement. We report the case of a 39-year-old, otherwise healthy male disfigured by an 8 × 7-cm hypopigmented and centrally atrophic annular plaque with erythematous indurated borders in an area of scar tissue on his forehead. Skin biopsies revealed non-caseating granulomas, and hilar involvement was identified, leading to the diagnosis of systemic sarcoidosis stage II with cutaneous involvement. The lesions proved resistant to multiple therapies, but responded within 4 months to adalimumab with regression of the lesion and inflammatory infiltrate. The visual analogue scale of disease activity decreased from 7/10 to 3.5/10, and the Dermatology Life Quality Index from 16/30 to 3/30 points. In conclusion, TNF-α inhibition can control inflammation and disfigurement by cutaneous sarcoidosis and restore quality of life.

Abstract
BACKGROUND This randomized phase III trial was designed to demonstrate the superiority of autologous peptide-loaded dendritic cell (DC) vaccination over standard dacarbazine (DTIC) chemotherapy in stage IV melanoma patients. PATIENTS AND METHODS DTIC 850 mg/m2 intravenously was applied in 4-week intervals. DC vaccines loaded with MHC class I and II-restricted peptides were applied subcutaneously at 2-week intervals for the first five vaccinations and every 4 weeks thereafter. The primary study end point was objective response (OR); secondary end points were toxicity, overall (OS) and progression-free survival (PFS). RESULTS At the time of the first interim analysis 55 patients had been enrolled into the DTIC and 53 into the DC-arm (ITT). OR was low (DTIC: 5.5%, DC: 3.8%), but not significantly different in the two arms. The Data Safety & Monitoring Board recommended closure of the study. Unscheduled subset analyses revealed that patients with normal serum LDH and/or stage M1a/b survived longer in both arms than those with elevated serum LDH and/or stage M1c. Only in the DC-arm did those patients with (i) an initial unimpaired general health status (Karnofsky = 100) or (ii) an HLA-A2+/HLA-B44- haplotype survive significantly longer than patients with a Karnofsky index <100 (P = 0.007 versus P = 0.057 in the DTIC-arm) or other HLA haplotypes (P = 0.04 versus P = 0.57 in DTIC-treated patients). CONCLUSIONS DC vaccination could not be demonstrated to be more effective than DTIC chemotherapy in stage IV melanoma patients. The observed association of overall performance status and HLA haplotype with overall survival for patients treated by DC vaccination should be tested in future trials employing DC vaccines.

Abstract
An 82-year-old female patient presented with a large perianal hyperkeratotic tumor extending into the anal canal. Staging did not reveal any metastatic spread. Diagnosis of verrucous carcinoma or Buschke-Löwenstein tumor, respectively, was based on typical clinical and histologic features. Moreover, human papillomavirus 6b DNA sequences could be detected by PCR. Surgical excision could not be performed due to the general health status of the patient; thus, alternative therapy methods were necessary. Treatment with imiquimod cream 5% (Aldara), a topical immune response modifier applied once a day and left for 12 h, led to significant partial tumor regression and clear demarcation of the tumor. The remaining tumor, now feasible for treatment with CO2 laser, was removed in two sessions in local anesthesia. In a third session, tumor parts in the anal canal were vaporized. This case demonstrates that the combination of imiquimod and CO2 laser ablation is an effective treatment option for verrucous carcinoma.

Abstract
We report a 50-year-old male patient with a 15-year history of psoriasis including mutilating psoriatic arthritis, in whom the withdrawal of cyclosporin A induced a generalised pustular exacerbation and a aggravation of the joint condition. Two weekly injections of 25 mg of the tumour necrosis factor alpha inhibitor etanercept led to a rapid improvement of his psoriatic arthritis, as well as regression of the pustular eruption, while residual erythema was still present. The clinical response was reflected by an increase in circulating interleukin (IL) 10 and a decrease in IL-6 and IL-8 serum levels during treatment. We conclude that etanercept may be a safe and effective therapy not only in severe psoriatic arthritis, but also in cases of pustular rebound after withdrawal of immunosuppressive agents.

Abstract
Interleukin-7 (IL-7) and IL-15 have been recently identified as growth factors for cutaneous T-cell lymphoma (CTCL) cells, and they protect these cells from cell death. Using the CTCL cell line SeAx as a test system now shows that IL-7 and IL-15 are indeed necessary to maintain high levels of bcl-2. The up-regulation of bcl-2 was paralleled by increased DNA-binding activities of the transcription factors STAT2, STAT5, STAT6, and c-Myb to bcl-2 gene promoter-enhancer elements. Because STAT5 and c-Myb positively regulate bcl-2, IL-7 and IL-15 may mediate some of their effects on cell death survival gene expression through these 2 factors. Constitutive activities of the 3 STAT factors and c-Myb were found in the IL-7- and IL-15-independent CTCL cell lines HUT78 and MyLa 2059. The c-Myb protein was also present in CTCL cells of the skin lesions of all investigated patients. These results indicate that IL-7 and IL-15 may increase bcl-2 expression in CTCL cells by the activation of c-myb and STAT factors.

Abstract
BACKGROUND Tumor-infiltrating lymphocytes (TILs) are considered to play an important role in the antitumoral immune response. The presence and percentage of CD8-positive tumor-infiltrating T cells have been shown to correlate with differentiation and prognosis in various neoplasms. The aim of this study was to determine the number of CD8-positive T cells in various primary cutaneous B-cell lymphoproliferative disorders and to evaluate its correlation with the histological type of tumor. METHODS Fifty-three lesions were examined by immunohistochemistry with antibodies targeting CD3, CD4, CD8 and TIA-1. Thirty-two lesions had been diagnosed as primary cutaneous B-cell lymphomas (CBCL) and 21 as B-cell pseudolymphomas (B-PSL). CBCLs included 15 follicular lymphomas (FL), 6 marginal zone lymphomas (MZL), and 11 diffuse large B-cell lymphomas (LCL). The number of CD8-positive cytotoxic T cells was determined by computer-assisted morphometrical microscopy. RESULTS No significant difference could be detected in the density of CD8-positive T cells in B-PSL (101/105 microm(2)), FL (110/105 microm(2)), and MZL (122/105 microm(2)). In contrast, the number of CD8-positive cells (55/105 microm(2)) in LCL was significantly lower (p<0.01) compared to B-PSL, FL and MZL. CONCLUSIONS In summary the number of CD8-positive T cells in B-cell lymphoproliferative disorders differs in regard to tumor type and differentiation with lowest numbers in diffuse large B-cell lymphomas. However, due to an overlap of the number of TILs, this parameter cannot be employed as a diagnostic parameter for individual cases.

Abstract
Immune evasion in lung cancer results from both structural and functional alterations of human leukocyte antigen (HLA) class I molecules and the local release of immunosuppressive cytokines. Recent data suggest that HLA-G, a nonclassical class Ib molecule, is involved in immune evasion by tumor cells. We sought to determine whether HLA-G could contribute to immunescape in lung cancer. All of 19 tumor specimens examined demonstrated detectable membrane-bound (HLA-G1), as well as soluble (HLA-G5) isoform transcription. Nine of 34 (26%) tumors were positive by immunohistochemistry using monoclonal antibody (mAb) 4H84, recognizing all denatured HLA-G isoforms, of which six were positive using mAb 16G1, recognizing soluble HLA-G. HLA-G immunoreactivity correlated with high-grade histology, with HLA-G being preferentially expressed on large-cell carcinomas. In these patients, loss of classical HLA class I molecules was observed to associate with HLA-G protein up-regulation. Moreover, we found interleukin-10 expressed in 15 of 34 (44%) tumors, and in most of the HLA-G-positive cases (7 of 9), suggesting up-modulation of HLA-G by interleukin-10. It is conceivable that HLA-G expression in lung cancer might be one of the ways how the tumor down-regulates host immune response, in addition to interleukin-10 production and HLA class I loss.

Abstract
On testing cutaneous T cell lymphoma cell lines and skin lesions, we found that the transcription factors STAT2, STAT3, STAT5, and STAT6 (STAT, signal transducer and activator of transcription) were present in the nuclei of these cells and that the binding to their specific DNA binding sites was stimulated by interleukin-7 and interleukin-15. DNA binding studies also revealed the presence of three additional DNA factors in cutaneous T cell lymphoma cells that bound to the same sequences and could also be stimulated by interleukin-7 and interleukin-15. One of these novel factors was also present in the adult T cell leukemia cell line Jurkat and malignant T cells from the blood of Sézary syndrome patients, but not in normal peripheral blood lymphocytes. It may therefore be a marker of T cell leukemia. It seems to interfere with the binding of STAT1 to the sis inducible element, suggesting that the DNA binding activity of STAT1 in cutaneous T cell lymphoma cells is disturbed.

Abstract
Cutaneous lymphomas of the cytotoxic phenotype, including CD8+ and CD56+ lymphomas, have only recently been recognized. To characterize the phenotypic profile of these lymphomas, we investigated the expression of both cytotoxic molecules and killer cell inhibitory receptors by immunohistochemistry techniques. Frozen sections from four CD8+ and from three CD56+ cutaneous lymphomas were stained for the cytotoxicity markers including T-cell restricted intracellular antigen-1, perforin, granzyme B, and for expression of the inhibitory receptors including p58.1, p58.2, p70, p140, CD94, NKG2, and leukocyte immunoglobulin-like receptor (LIR-1). Apart from LIR-1, the CD8+ lymphomas in our series express p70 and p140 from the inhibitory receptors and only one or two of the cytotoxic proteins. The CD56+ lymphomas, on the other hand, express only LIR-1 of the set of inhibitory receptors and the whole panel of cytotoxic antigens. Various subtypes of cytotoxic cutaneous lymphomas (CD8+ and CD56+) differ in regard to their phenotypic and functional profile, which may explain differences in their biological behavior.

Abstract
A 50-year-old patient, suffering from familial polyposis (Gardner's syndrome), initially presented with several nodules on his left arm. Histological examination revealed primary cutaneous T-cell-rich B-cell lymphoma (TCRBCL). Staging procedures failed to detect any systemic involvement. Three years after total excision of the tumours, the patient presented with a non-specific dermatitis, enlarged axillary lymph nodes and splenomegaly. Histological and immunohistochemical examination of lymph node and spleen biopsy specimens resulted in the diagnosis of Hodgkin's disease (HD) of the nodular sclerosis type. Sequence analysis of single cells micromanipulated from skin and from lymph node lesions indicated that both lymphoma infiltrates were derived from the same precursor germinal centre B-cell clone. This is a case showing a clonal relationship between TCRBCL and HD, providing support to the B-cell origin of Hodgkin and Reed-Sternberg cells.

Abstract
Deregulated expression of the transcription factor PAX3 was observed previously in several tumors like rhabdomyosarcoma and Ewing's sarcoma. Because PAX3 expression is also found in pluripotent neural crest cells, we investigated whether melanomas, tumors derived mostly from cutaneous intraepidermal melanocytes, might show deregulated PAX3 expression. Using a specific and sensitive reverse transcription-PCR, we detected PAX3 mRNA in 77% (27 of 35) of primary cultured melanomas. These results could be confirmed by direct in situ hybridization on the corresponding tissue sections where PAX3 expression was unambiguously confined to tumor cells and not detected in surrounding normal tissue, normal skin sections, or sections of benign lesions. Furthermore, down-regulation of PAX3 expression achieved through a specific antisense oligonucleotide-based treatment resulted in > 70% of dead cells specifically in PAX3-positive melanomas. Annexin V staining confirmed that primary melanoma cells underwent apoptosis after treatment These experiments suggest that in situ hybridization of PAX3 on paraffin-embedded tissue may represent a novel means to identify melanoma cell lesions, which appear to become dependent on expression of this deregulated transcription factor.

Abstract
Melanoma tumor thickness is a major prognostic factor. Thin lesions, however, may metastasize, and sometimes thick tumors may not. To investigate the role of HLA class I-mediated antigen presentation, we correlated the expression of components of the antigen-processing machinery in primary melanoma lesions with their thickness and with the development of metastases. Seventeen formalin-fixed, paraffin-embedded primary melanomas thinner than 0.76 mm and 21 thicker than 1.50 mm were stained with anti-LMP2, -LMP7, -TAP1, -TAP2, -HLA class I and -beta2-microglobulin monoclonal antibodies. Twenty patients remained tumor-free in the follow-up period (10.5 +/- 1.8 years). Eighteen patients relapsed within a median period of 15.0 months following tumor excision. Expression of all markers in the tested lesions was down-regulated, the frequency ranging from about 40% for LMP and TAP subunits to about 70% for HLA class I antigens. Expression of all markers was not correlated with tumor thickness. Only TAP1 and TAP2 down-regulation was significantly (p = 0.026 and 0.042, respectively) correlated with the development of metastases. This correlation was independent of tumor thickness for TAP1. We suggest that TAP1 and probably TAP2 expression in primary lesions represents an independent prognostic marker in melanoma. Abnormalities in antigen presentation may account for the lack of absolute correlation between tumor thickness and prognosis.

Abstract
Microarray analysis is a promising new approach for creating specific expression profiles of multiple genes simultaneously. We quantitatively analyzed differential gene expression patterns in mycosis fungoides-derived clonal T cells and autologous, identically cultured CD4+ lymphocytes using microarrays containing 588 cDNA segments from genes relevant to cell signaling, carcinogenesis, and apoptosis. Among other dissimilarities, neoplastic T cells showed coexpression of CD40 (Bp50) and CD40 ligand (gp39, CD154). These results could be corroborated by reverse transcription-PCR, immunohistochemistry, and two-color immunofluorescence staining. Our data suggest that in cutaneous T-cell lymphoma, CD40/CD40 ligand interactions might represent a paracrine loop that is crucial not only in preventing apoptosis or positively regulating growth but also in homing of neoplastic cells to the skin.

Abstract
The genetic alterations responsible for the development of cutaneous lymphoma are largely unknown. Chromosome region 9p21 contains a gene locus encoding an inhibitor of cyclin-dependent kinase 4, and heterozygous deletions of this tumor suppressor gene (p16) have been shown in a variety of malignant tumors. We studied 11 randomly selected cutaneous CD30-positive large cell lymphomas. Several areas containing 20-50 CD30-positive lymphocytes were microdissected in each case and subjected to single-step DNA extraction. Loss of heterozygosity analysis was performed using polymorphic markers at 9p21 (IFNA, D9S171, D9S169) and 17p13 (TP53). Samples from normal cells apart from CD30-positive lymphocytes, e.g., CD30-negative lymphohistiocytic infiltrates and normal epidermal layer, were also obtained in all cases from the same slide for comparison with the tumor samples. Expression of CD30 and T-lineage antigens (CD3, CD45Ro) was confirmed in all cases. Immunohistochemical staining for p16 and p53 was performed using the monoclonal antibodies sc-1661 and DO-7, respectively. Of the 11 informative cases, seven (64%) exhibited loss of heterozygosity at least for one marker at 9p21 (p16), whereas no allelic deletions were found for the polymorphic marker at 17p13 (p53). On immunohistochemistry loss of the p16 protein was detected in two of 11 cases. Nuclear staining for p53 protein was found in four of 11 cases. Here, we provide the first evidence of the involvement of the tumor suppressor gene p16 in primary cutaneous large cell lymphoma. Whether p16 deletion in these lymphomas is associated with disease progression and whether this method could serve as an early marker to detect lymphomas at an early stage needs to be addressed in future studies.

Abstract
Cutaneous lymphomas are a heterogeneous group of lymphoproliferative disorders derived from T cells, B cells and, in rare cases, natural killer cells. The precise mechanisms of the lymphomagenesis are still obscure. However, there are various factors involved. These factors include environmental, especially infectious factors, translocations, mutations and genetic instability. The special microenvironment in the skin is responsible for the peculiar behavior of these neoplasms by providing various key factors, such as adhesion molecules and cytokines. Newly identified molecular disturbances in cutaneous lymphomas might be targeted by specific molecular or immunologic interventions in the future.

Abstract
BACKGROUND Pemphigus is a disease showing an uneven geographical distribution. In Bulgaria pemphigus has always represented a substantial part of diagnosed bullous diseases, but previous epidemiological data are incomplete. Our purpose was to evaluate retrospectively the incidence and prevalence of pemphigus in the district of Sofia (the capital of Bulgaria; population 1 200 000) for a sixteen-year period. METHODS The files of all the newly registered patients with pemphigus in the City Hospital of Dermatology in Sofia during the period Jan 1 1980 to Dec 31 1995, were collected and analysed with regard to personal statistics, ethnic origin, profession, history of the disease including age and season of onset, symptoms, clinical diagnosis, severity, laboratory findings, associated illnesses, therapy, and cure rate. Special attention was paid to smoking, alcohol abuse, and the presence of triggering factors such as emotional stress, drug intake, underlying diseases, neoplasias, or others. RESULTS During the 16-year period studied, 74 newly diagnosed cases of pemphigus occurred in the district of Sofia, giving a prevalence of 0.38 per 100 000 inhabitants and a mean incidence of 0.47/100 000/year for the overall population and 0.51/100 000/year for the population aged above 20 years. The most common clinical variant is pemphigus vulgaris, frequently occurring in the fifth-sixth decades. The vast majority of the patients are workers or professionals. CONCLUSIONS The results of the present retrospective study reveal a relatively high prevalence and incidence of pemphigus in Bulgaria, compared to that encountered in other countries. Our data is similar to that reported from Greece. Whether the Balkan Peninsula represents a focus of population groups with high susceptibility to pemphigus is a problem which could be highlighted by further epidemiological studies in this geographic area.

Abstract
In advanced stages of malignant melanoma (MM), metastases to the CNS are frequently observed. Few results are available on trophic factors and immunological features involved in the process of invasion and adhesion of circulating metastatic cells into the CNS. A direct comparison of remote metastases found in different locations of the same patient might help to identify such properties. For this purpose, we screened a panel of MM cell cultures, which had been established from patients with surgically removed MM lesions of the CNS, for expression and regulation of immunorelevant molecules. The results were compared with standard controls and cultures established from non-CNS metastatic lesions of the same patients. No significant differences were observed for expression of HLA-I, HLA-II, ICAM-1 and the melanoma-associated antigens Mage-3, MelanA and tyrosinase. Constitutive expression of the neuronal cell adhesion molecule (NCAM) was found in all CNS-derived samples and in fewer than 50% of non-CNS derived cultures. IFN-gamma was found to have a weak up-regulating effect in all non-CNS-derived cultures, except normal melanocytes. However, in 6/7 CNS-derived cultures, pre-treatment with IFN-gamma reduced expression of NCAM to 28% to 77% of the level in untreated cultures. The presence and regulation of NCAM differs between MM cells derived from CNS metastases and non-CNS-derived melanocytic cells. Thus, NCAM might be a candidate immunoregulating molecule involved in the formation of CNS metastases of MM.

Abstract
Malignant melanoma is an antigenic tumor recognized by specific lymphocytes. Several melanoma-associated antigens have been shown to cause tumor rejection in vitro. Escape from immunosurveillance by melanoma cells is the result of several mechanisms such as total loss or decreased expression of HLA antigens, alterations in the expression of tumor-associated antigens or deficiencies in the antigen-processing machinery. Additional important features include the influence of endogenous and exogenous cytokines such as interferons or interleukins and expression of adhesion molecules or co-stimulatory molecules. All these factor have to be considered for the development of new immunoregulatory treatment modalities against advanced melanoma.

Abstract
Mycosis fungoides (MF) and Sézary syndrome (SS) are closely related cutaneous T-cell lymphomas, which differ in several clinical aspects. We compared histological and immunophenotypical features of these two entities, which could be implicated in the dermotropism and epidermotropism, characteristic for both of them. Thirteen biopsy specimens from patients with established plaque-stage MF and 13 from SS patients were examined retrospectively, and 21 histological criteria were assessed. Further, 9 cryosections from MF lesions and 9 from SS lesions were stained for LFA, ICAM1, CD40, CD40-ligand, CD28, CD80, CTLA-4, CD86, FAS, FAS-ligand, CLA and CD15s. The only histological criteria that showed persistent differences were acanthosis (in 12 of 13 SS and in 7 of 13 MF specimens) and Pautrier collections (detected in 6 SS and 11 MF biopsies). Patterns of staining with the antibodies mentioned above were found to be similar. Our results indicate that these interaction molecules seem to be involved in the pathogenesis of MF and SS, but their immunohistochemical distribution does not contribute to the differentiation between the two entities.

Abstract
Monoclonal antibody (MAb) A103 specifically detects Melan A/MART-1 protein expression. Melan A/MART-1-derived peptides are recognized by CD8+ T-cells and are used in immunotherapy. We examined formalin-fixed paraffin-embedded tissue from 57 melanomas (34 primary, 23 metastatic) and 39 control cases (junctional, dermal, compound, Spitz, Reed and balloon-cell naevi) using the alkaline phosphatase and anti-alkaline phosphatase immunochemical method after antigen retrieval. Immunoreactivity was rated as low, medium or high, and staining pattern as homogeneous or heterogeneous. Staining with MAb A103 showed a sensitivity of 88% for melanoma, with a very high specificity for melanocytic cells. Immunopositivity decreased along with clinical stage, with stage I showing 100%, stage II 88%, stage III 90% and stage IV 75% immunoreactivity. Staining changed from an exclusively homogeneous pattern in the early clinical stages to a more heterogeneous pattern in the later stages. Melanocytic control tissues consisting of naevi of different subtypes all showed weak to moderate homogeneous immunoreactivity, with polarity towards the epidermis. Analysis of short-term melanoma cell cultures using reverse transcription-polymerase chain reaction (RT-PCR) enzyme-linked immunosorbent assay (ELISA) demonstrated mRNA expression in only one third of the originally immunopositive tumours, suggesting rapid mRNA expression loss in culture. MAb A103 allows the detection of melanoma-associated Melan A/MART-1 protein expression in routine archival tissue and thus enables the profiling of melanomas suited for immunotherapy approaches involving Melan A/MART-1 derived epitopes.

Abstract
Monoclonal antibody T311 specifically detects tyrosinase protein expression. Tyrosinase-derived peptides are recognized by CD8+ T-cells and applied in immunotherapy. We examined formalin-fixed paraffin-embedded tissue of 50 melanoma (primary n=31, metastatic n=19) and 41 control cases (junctional, dermal, compound, Spitz, Reed, balloon-cell nevi) by immunochemistry using the alkaline phosphatase-anti-alkaline phosphatase method after antigen retrieval. Staining with mAb T311 showed a sensitivity of 94% for melanoma with a very high specificity for melanocytic cells. Immunopositivity (94% of melanomas overall) correlated inversely with clinical stage: clinical stage I and stage II showed 100%, stage III and stage IV 86% immunoreactivity each. Staining changed from an exclusively homogeneous pattern in early stages to a more heterogeneous pattern in later stages. Melanocytic control tissue like nevi of different subtypes all showed weak to moderate, homogeneous immunoreactivity with polarity towards the epidermis. RT-PCR ELISA analysis of short-term melanoma cell cultures displayed mRNA expression in only half of the originally immunopositive tumors only, suggesting rapid mRNA expression loss in culture. mAb T311 allows detection of melanoma-associated tyrosinase protein expression and thus profiling of melanomas using routine archival tissue suited for immunotherapy approaches involving tyrosinase derived epitopes.

Abstract
Monoclonal antibody 57B specifically detects MAGE-3 gene protein expression. MAGE-derived peptides are recognized by CD8+ T cells and applied in immunotherapy. We examined formalin-fixed, paraffin-embedded tissue of 61 melanoma (primary, n = 40; metastatic, n = 21) and 46 control cases (junctional, dermal, compound, Spitz, Reed, and balloon-cell nevi) by immunohistochemistry using the alkaline phosphatase anti-alkaline phosphatase method after antigen retrieval. Immunoreactivity was rated positive at 20 positive cells per tumor or more. Staining pattern was homogeneous, scattered, or focal. All control samples and internal controls were immunonegative. Staining with monoclonal antibody 57B showed a specificity of 100% with a sensitivity of 44%. Immunopositivity (overall, 44% of melanomas) increased along with tumor, node, and metastasis stage; pT1 showed 13%, pT2 22%, pT3a 29%, pT3b 45%, pT4 100%, pTxN1 60%, and pTxNxM1a 63% of samples positive. The staining pattern was homogeneous on pT1 to pT3a tumors, homogeneous or focal in pT3b and pT4a, and homogeneous, focal, or scattered in pTxN1 and pTxNxM1a. The frequency of immunopositivity relates well to data on mRNA expression using reverse transcriptase polymerase chain reaction in a subgroup analyzed by both methods. Monoclonal antibody 57B can be used to allow profiling of melanomas using routine archival tissue, when considering immunotherapeutic approaches involving MAGE-3-derived epitopes.
