We performed an immunohistochemical study of BCA-225, which is a glycoprotein secreted by the T47D breast carcinoma cell line and recognized by monoclonal antibody BRST-1 (clone name: CU-18), in normal skin and various skin cancers. In normal skin, BCA-225 was positive only in the secretory portion of both eccrine and apocrine glands and in mature cells of the sebaceous gland. We observed 10 cases of squamous cell carcinoma of the skin, 10 cases of basal cell carcinoma without sebaceous differentiation, 3 cases of basal cell carcinoma with sebaceous differentiation, 6 cases of malignant trichilemmoma, 8 cases of eccrine porocarcinoma, 3 cases of ductal carcinoma, 1 case of malignant clear cell hidradenoma, 1 case of apocrine adenocarcinoma, 6 cases of extra-ocular sebaceous carcinoma, 5 cases of extramammary Paget's disease with underlying adenocarcinoma, and 11 cases of extramammary Paget's disease without underlying adenocarcinoma. Most of the cases of sweat gland carcinoma, basal cell carcinoma with sebaceous differentiation, sebaceous carcinoma, and extramammary Paget's disease were positive for BCA-225, while none of the cases of squamous cell carcinoma, basal cell carcinoma without sebaceous differentiation, or malignant trichilemoma were positive. Based on these findings, we believe that BCA-225 is useful in distinguishing tumors with sweat gland and sebaceous differentiation and extramammary Paget's disease from tumors without such differentiation. 相似文献

A 64-year-old woman was referred to our hospital with complaints of erosion in the anal region and rectal bleeding. The histopathological examination revealed Paget cells in an epidermis lesion of the skin and rectal carcinoma. The cells were positive for PAS, CEA, and CK20, and negative for GCDFP15 and CK7. Electron microscopic examination revealed the presence of many microvilli in the epidermal Paget cells as well as in the tumor cells and rectum itself. The results suggested that electron microscopy is a very useful technique to differentiate extramammary Paget's disease and pagetoid phenomenon. In the present case, the perianal skin lesion was proved to be due to intraepidermal spread of the rectal carcinoma, or so-called pagetoid phenomenon. 相似文献

Formalin-fixed and paraffin-embedded tissue specimens of six cases of extraocular sebaceous carcinoma were studied immunohistochemically with eight anti-keratin monoclonal antibodies, 34βB4, 35βH11, Ks13.1, Ks19.1, PKK1, LP34, KL1 and AE1. The staining patterns of sebaceous carcinoma were compared with those of normal sebaceous glands and other skin cancers which should be distinguished from sebaceous carcinoma histopathologically. The other skin cancers compared were eccrine porocarcinoma, malignant clear cell hidradenoma, extramammary Paget's disease with underlying adenocarcinoma, malignant trichilemmoma, and squamous cell carcinoma. Most cases of sebaceous carcinoma were stained with 35βH11, Ks19.1, LP34, KL1 and AE1, while normal sebaceous glands were positive only with 35βH11, LP34, KL1 and AE1. By immunostaining, sebaceous carcinoma was distinguishable from extramammary Paget's disease with underlying adenocarcinoma, squamous cell carcinoma, malignant trichilemmoma, and eccrine porocarcinoma, but was not clearly distinguishable from malignant clear cell hidradenoma. These findings demonstrate that sebaceous carcinoma shows positive reactions with antibodies to simple epithelial keratin, probably as a result of neoplastic transformation, and that immunohistochemical examination using anti-keratin monoclonal antibodies is useful in distinguishing sebaceous carcinoma from several other skin cancers. 相似文献

Primary extramammary Paget's disease is thought to be an intraepidermal carcinoma indicating apocrine secretory differentiation. In addition to expression in breast tissue, human milk fat globulin (HMFG) is expressed in the normal apocrine glands and tumours with apocrine differentiation. In this study HMFG expression in extramammary Paget's disease was analysed immunohistochemically in 18 cases of primary extramammary Paget's disease and two cases of secondary extramammary Paget's disease. The proportion and staining pattern of positive tumour cells with the anti-HMFG antibody was variable in each case. Cytoplasmic staining was observed frequently in dermal invasion and metastasis of Paget cells. The variabilities were thought to be due to modulation of the cellular localization of the cell surface component, HMFG, according to changes in cellular differentiation or malignant potency. 相似文献

Immunohistochemical stains in extramammary Paget's disease. 总被引:3,自引:0,他引:3
The histologic and immunohistochemical characteristics of 49 skin biopsy specimens from 49 patients with extramammary Paget's disease were studied. Patients with extramammary Paget's disease with and without underlying malignant disease were identified. Associated malignant lesions, present in 16 patients (33%), were transitional cell carcinoma of the bladder (n = 8), adenocarcinoma underlying the skin (n = 3), adenocarcinoma of the anus (n = 1), adenocarcinoma of the vulva (n = 1), apocrine carcinoma (n = 1), prostate carcinoma (n = 1), and carcinoma metastatic to the lung (n = 1). The main histologic feature was the presence of Paget's cells, predominantly at the base of the epidermis. In 6% of the cases, well-defined nests of large Paget's cells mimicked melanocytic nests. Carcinoembryonic antigen and Cam 5.2 (a monoclonal antibody that stains 40-kDa, 45-kDa, and 52.5-kDa low molecular weight keratins) were localized to the Paget's cells in 42 of 45 (93%) and 29 of 41 cases (71%), respectively. Forty-four of 46 lesions (96%) were mucin positive, as determined by Hale's colloidal iron stain. Absence of staining for colloidal iron and carcinoembryonic antigen occurred somewhat more frequently in patients with underlying malignant disease than in patients without tumors (13% vs. 0% mucin negative and 13% vs. 3% carcinoembryonic antigen negative, respectively). Although immunohistochemical staining for low molecular weight keratin may be used to confirm the diagnosis of extramammary Paget's disease, Cam 5.2 is not as sensitive as the colloidal iron or carcinoembryonic antigen stain. 相似文献

Using the PAP technique, paraffin-embedded and formalin-fixed tissue sections taken from 11 patients suffering from Paget's disease (5 mammary, 6 extramammary cases) were stained with antibodies against keratin, actin, S 100 protein, CEA, HMFG 1, cytokeratin 6 and 18 (Dako-CK-1), as well as the lectin SBA. We did not find any differences between mammary and extramammary Paget's disease. In both forms of the disease, all tumor cells showed reaction to antibodies against HMFG 1 and CEA and, in 50 to 100%, to the lectin SBA. The other antibodies investigated did not react with Paget's cells. Since HMFG 1 and Dako-CK-1 are selective markers of apocrine and eccrine sweat gland structures, respectively, our results suggest apocrine differentiation of both mammary and extramammary Paget's disease. At the same time, our findings rule out a possible histogenesis of Paget's cells from melanocytes (positive for S 100 protein) or keratinocytes (positive for Dako-CK-1 and antikeratin). 相似文献

We examined 32 cases (38 lesions) of extramammary Paget's disease (EMPD) in relation to comparative studies on intraductal carcinoma of the breast (ductal carcinoma in situ, DCIS) and apocrine adenocarcinoma (AAC). Lesions included scrotum (18 lesions), vulva (8), axilla (6), groin (3), penis (2) and chest wall (1), and the distribution was compatible with that of apocrine or supernumerary mammary glands. Histologically, extra-mammary Paget's and DCIS cells exhibited a large amount of a pale-stained cytoplasm. The cytoplasm of AAC cells frequently contained granules, was eosinophilic and differed from that of Paget's or DCIS cells. Immunohistochemical studies revealed positive reactions for polyclonal and monoclonal antibodies to carcinoembryonic antigen in all EMPD and most DCIS, but not in AAC. Recent studies have shown that extramammary Paget's cells exhibit characteristics of glandular epithelial cells and that most cases of EMPD are not accompanied by an underlying carcinoma. The results obtained in this study, coupled with data on the frequency of the supernumerary breasts, lead to the speculation that extramammary Paget's cells originate from ectopic mammary glands or from pluripotential germinative cells in the epidermis, capable of differentiating toward the mammary glands. 相似文献

Seven cases of mammary and twelve cases of extramammary Paget's disease were studied for the presence of carcinoembryonic antigen (CEA) and apocrine epithelial antigen (AEA) using the immunoperoxidase technique. CEA was found in the Paget cells in five out of seven mammary and in all twelve cases of extramammary Paget's disease, whereas the AEA reaction was positive in six mammary and all extramammary cases. The same antigens were also found in the cells of intraductal or ductal adenocarcinomas of the breast associated with mammary Paget's disease, suggesting a common origin for the cells. In the cases of extramammary Paget's disease studied no underlying malignant neoplasms could be detected. Our findings support the suggestion that Paget cells originate in sweat gland ducts and undergo an apocrine differentiation. 相似文献

Extramammary Paget's disease is a rare cutaneous adenocarcinoma, usually of epidermal origin and glandular differentiation and frequently associated with an underlying adnexal carcinoma and perhaps with underlying internal malignancy. One hundred ninety-seven cases of extramammary Paget's disease (196 cases reported in the English literature from 1962 to 1982 and one case of my own) are reviewed. It remains a rare cutaneous malignancy that occurs primarily in elderly people. It is seen more frequently in women than in men and occurs predominantly in vulvar and perianal locations. Twenty-six percent of patients with this disease will ultimately die of it or an associated internal malignancy. Twenty-four percent of patients with the disease have an associated underlying cutaneous adnexal adenocarcinoma. These patients have a higher mortality rate--46%--than patients with extramammary Paget's disease without underlying cutaneous adnexal adenocarcinoma. Twelve percent of patients with extramammary Paget's disease have an associated concurrent underlying internal malignancy. The location of the underlying internal malignancy appears to be closely related to the location of the extramammary Paget's disease--i.e., a perianal location is associated with adenocarcinoma of the digestive system, a penile-scrotal-groin location with genitourinary malignancy, etc. A directed internal malignancy search may be of benefit in patients who are diagnosed as having extramammary Paget's disease. 相似文献

Background: While cytokeratin 7 is a reliable marker for most cases of Paget's disease, it is not 100% sensitive. Moreover, cases of cytokeratin 7-positive pagetoid squamous cell carcinoma in situ are reported in the literature. The monoclonal antibody Ber-EP4 is diagnostically highly reliable in the differentiation between basal cell carcinoma and cutaneous squamous cell carcinoma. Here we report its application in the differential diagnosis of cutaneous pagetoid neoplasms.
Methods: Biopsy samples from 21 cases of extramammary Paget's disease, 12 pagetoid squamous cell carcinomas in situ and 10 pagetoid melanomas in situ of the superficial spreading type were examined immunohistochemically with Ber-EP4, 34βE12 and HMB-45.
Results: Ber-EP4 selectively labeled all cases of extramammary Paget's disease but none of the other pagetoid neoplasms. The majority of cases (18 = 85.7%) displayed strong and three (14.3%) showed moderate immunoreactivity.
Conclusions: Ber-EP4 reliably differentiates extramammary Paget's disease from pagetoid squamous cell carcinoma in situ and pagetoid melanoma in situ . The antibody should be included along with a panel of other markers when evaluating for pagetoid cutaneous neoplasms in order to avoid a possible misdiagnosis of pagetoid squamous cell carcinoma in situ . 相似文献

The use of cytokeratins 7 and 20 in the diagnosis of primary and secondary extramammary Paget's disease 总被引:5,自引:0,他引:5
Despite the similarity in clinical appearance, there is a significant difference in the prognosis between primary extramammary Paget's disease (EPD) and the pagetoid spread of underlying regional internal malignancy (secondary EPD, pagetoid phenomenon). Fifteen cases of primary EPD (11 carcinoma in situ and four invasive carcinoma), seven cases of secondary EPD (five colorectal adenocarcinoma and two urothelial carcinoma), and six cases of anal canal carcinoma were retrieved and analysed immunohistochemically using six kinds of monoclonal anticytokeratin antibodies. No expression of cytokeratins 1, 5, 10, 13 and 14 was observed in any cases examined in this study. All 15 cases of primary EPD had the immunophenotype cytokeratin (CK)7+/CK20-. CK20 expression was diffusely positive in six cases of secondary pagetoid spread (two urothelial carcinoma and four colorectal adenocarcinoma), and focally in one case (a colorectal adenocarcinoma). In anal canal carcinoma, three of six cases showed CK20 diffuse expression and the remaining three cases expressed CK20 focally. CK7 expression was observed in three of six cases of anal canal carcinoma and in two of five cases of secondary EPD associated with colorectal adenocarcinoma. The combination of CK7 and CK20 demonstrates these to be useful markers in distinguishing 'primary' EPD from a pagetoid spread of extracutaneous malignancies. Namely, immunophenotypes other than CK7+/CK20- in Paget cells suggest underlying regional internal malignancy. 相似文献

A patient with perianal extramammary Paget's disease (EMPD) occurring simultaneously with prostatic adenocarcinoma is presented. Four previously reported cases of genital EMPD associated with prostatic carcinoma are reviewed. The use of immunohistologic techniques to help establish the diagnosis in some cases, and the relationship of EMPD to underlying adenocarcinoma of sweat glands and of the lower urinary and gastrointestinal tracts is discussed. The importance of a directed search for internal malignancy in the individual patient with EMPD is emphasised. 相似文献

Mammary and extramammary Paget''s disease 总被引:2,自引:0,他引:2
J Kanitakis 《Journal of the European Academy of Dermatology and Venereology》2007,21(5):581-590
Paget's disease is an intra-epidermal adenocarcinoma seen over the nipple/areola (mammary Paget's disease) or in extramammary body zones, such as the anogenital and perineal skin and the axilla. Mammary and extramammary Paget's disease share many common clinicopathological features but also show several differences, namely, with regard to pathogenesis and association with underlying malignancies. Indeed, mammary Paget's disease is as a rule associated with an underlying breast carcinoma whereas association of extramammary Paget's disease with underlying (skin or visceral) malignancies occurs much less frequently. We review here the main clinicopathological and therapeutic features of mammary and extramammary Paget's disease. 相似文献

Extramammary Paget's disease (EMPD) is considered to be an intraepithelial adenocarcinoma. Typically involved anatomical sites are the vulvar, perianal, perineal, scrotal and penile regions. Clinically, the lesions present as well-defined, moist, erythematous plaques usually accompanied by pruritus. An unusual feature of EMPD is its association with cutaneous, adnexal-structure adenocarcinomas and its association with internal malignancies. Histopathological examination shows epidermal acanthosis and elongated rete ridges. Paget's cells are large intraepidermal cells with a large nucleous and abundant pale cytoplasm. Recent studies of perianal and vulvar EMPD have described distinct immunohistochemical subtypes termed cutaneous and endodermal. Cutaneous EMPD is characteristically positive for cytokeratin (CK)7, negative for CK20, and positive for gross cystic disease fluid protein (GCDFP)15+, whereas endodermal EMPD shows a CK7+ CK20+ GCDFP15− phenotype. Surgery remains the treatment of choice, with either wide surgical excision or Mohs' micrographic surgery. We present a case of EMPD with an underlying carcinoma, which combined immunohistochemical findings suggestive of the cutaneous subtype (positive for CK7, GCDFP15, mucin (MUC)1, human epidermal growth factor receptor (HER)2/neu positive) and the endodermal subtype, frequently associated with internal malignancy (CK20, MUC2, CDX-2 positve); however, our patient had no associated internal malignancy. 相似文献

Anhidrosis/hypohidrosis are conditions presenting various level of sweating dysfunction. Among them, acquired idiopathic generalized anhidrosis (AIGA) presents inadequate decrease or loss of sweating without apparent neurological and dermatological symptoms except cholinergic urticaria. Recently, serum level of carcinoembryonic antigen (CEA), one of the most well‐known tumor markers, has been proposed as a clinical marker reflecting activity of AIGA. This study was performed to verify the specificity and independence of serum CEA level from the other serum tumor markers especially related to adenocarcinoma. The expression of various tumor markers in the serum collected from three healthy control subjects, four AIGA cases, and a cholinergic urticaria (CU) case with elevation of serum CEA level and history of hyperthermia was analyzed using a membrane‐based antibody array. In all AIGA and CU cases, the intensity of CEA was significantly increased (7.60–15.9 times compared with that of control), relatively well‐reflecting the serum CEA level, and the mean intensity of CEA was 11.8 times higher than the control subjects (P = 0.0011). On the other hand, the ratio of carbohydrate antigen (CA)125 and CA19‐9 was 1.93 and 0.23 times compared with the mean intensity of the control subjects, respectively, and there was no statistical significance. Immunohistochemistry on 10 AIGA cases showed increased expression of CEA but not CA19‐9 and CA125 in the eccrine sweat glands. In conclusion, the elevation of serum CEA level was independent from the other tumor markers in hypohidrotic condition represented by AIGA. 相似文献

RCAS1 antigen is highly expressed in extramammary Paget's disease and in advanced stage squamous cell carcinoma of the skin 总被引:7,自引:0,他引:7

Receptor-binding cancer antigen expressed on SiSo cells (RCAS1), which is a type II membrane protein expressed on cervical carcinoma cells, induces apoptosis in RCAS1 receptor expressing cells. RCAS1 is thus presumed to protect tumor cells from immune surveillance by infiltrating RCAS1 receptor-positive immunocytes (Sonoda et al. Int J Oncol 1995; 6: 1899-1904; Nakashima et al. Nature Med 1999; 5: 938-942). We performed immunohistochemical analysis of RCAS1 expression in various skin tumors. RCAS1 was not detected in normal human epidermis. One of 21 seborrheic keratosis (4.8%), one of 12 actinic keratosis (8.3%), two of 16 keratoacanthomas (12.5%), and two of 14 basal cell carcinomas (14.2%) expressed RCAS1. RCAS1 was not detected in Bowen's disease (0/17). RCAS1 was positive in 45 of 61 (73.8%) squamous cell carcinomas. Interestingly, the expression of RCAS1 was mostly correlated with clinical stages of squamous cell carcinoma. It was found that 46.1% of stage I, 61.1% of stage II, 85.7% of stage III, and 83.3% of stage IV squamous cell carcinomas were RCAS1-positive. In addition, RCAS1 was found to be highly expressed in extramammary Paget's disease. Fifty nine of 63 extramammary Paget's disease samples (93.7%) were positive for RCAS1. Fifty eight (92%) showed co-expression of RCAS1 and carcinoembryonic antigen (CEA). While two of 24 cases of melanoma (8.3%) expressed RCAS1 antigen, none of 20 cases of nevus pigmentosus showed positive staining. These results indicate that RCAS1 is a highly sensitive marker for extramammary Paget's disease. RCAS1 is also expressed in various skin tumors including squamous cell carcinoma, where positive correlation with clinical staging was documented. 相似文献

Tissue from a 66-year-old male patient with extramammary Paget's disease of the right side of the scrotum and the right groin was studied for the presence of several antigens with the immunoperoxidase technic. Adenokeratin (cytokeratin No. 18) and carcinoembryonic antigens were positive in Paget's cells, whereas squamokeratin (cytokeratin No. 10) was expressed only in normal epidermal cells. Langerhans cells were decreased in the region of the tumor. Many transferrin receptors were present on the tumor cells, indicating a high cellular proliferation rate. Enzyme histochemical studies of the extramammary Paget's cells showed positive reactions for several enzymes typical of sweat glands, except for leucine aminopeptidase, which was negative. A comparison with three other cases showed that these enzyme reactions varied greatly from case to case. Both immunohistochemical and enzyme histochemical findings provide further evidence that extramammary Paget's cells are related to sweat gland epithelial cells, with variable expression of cellular characteristics. 相似文献

Triple extramammary Paget's disease, which consists ordinarily of bilateral axillary and genital lesions, is uncommon. Triple extramammary Paget's disease involving other sites has never been reported, although solitary extramammary Paget's disease can occur at various sites around the body. Erythematous plaques on the areola, axilla and genitalia of a 91-year-old man were surgically removed under the clinical diagnosis of multiple extramammary Paget's disease. Histology revealed that all three lesions consisted of intraepidermal nests of Paget cells and other isolated Paget cells scattered in the epidermis. Although adnexal invasion was observed in the genital lesion, neither intraductal invasion nor underlying breast carcinoma was detected in the areolar lesion. Immunohistochemically, the Paget cells in all lesions expressed simple epithelial cytokeratins (CK8, 18 and 19), mucin (MUC)1 and MUC5AC, but neither CK20 nor MUC2. From the histological findings, the present case was interpreted as triple extramammary Paget's disease rather than synchronous mammary and extramammary Paget's disease. Furthermore, the mucin core protein expression pattern, which was identical to that observed in extramammary Paget's disease, supported the above interpretation. 相似文献

Most cases of extramammary Paget’s disease are diagnosed at an early stage. For advanced cases, few effective treatments are available and the prognosis is poor. Therefore, developing sensitive biomarkers for metastatic cases is a critical challenge. Carcinoembryonic antigen (CEA) and cytokeratin 19 fragment (CYFRA) are two potentially useful biomarkers. In the present retrospective large-scale study, we identified other potential biomarkers of lymph node metastasis. Patients with extramammary Paget’s disease who visited our dermatology clinic between April 2004 and March 2019 (n = 138; mean age, 73.4 years; 85 men and 53 women) were enrolled in the study. The patients were divided into three groups according to the presence of regional lymph node metastasis and distant metastasis to evaluate the relationship between metastasis and various tumor markers: serum CEA, carbohydrate antigen (CA)19-9, CA125, CA15-3 and CYFRA. For distal metastasis, each biomarker had high sensitivity and specificity. The sensitivities and specificities for regional lymph node metastasis were as follows: CEA, 50.0% and 88.6%; CA19-9, 50% and 89.5%; CA125, 0% and 98.2%; CA15-3, 0% and 96.0%; and CYFRA, 66.7% and 95.0%, respectively. We also analyzed biomarker combinations. The sensitivity and specificity of the combination of all five biomarkers (CEA, CA19-9, CA125, CA15-3 and CYFRA) were 83.3% and 70.9%, respectively. The sensitivity of the combination of just CEA and CYFRA was also 83.3%. Screening for combinations of these biomarkers will facilitate the detection of early lymph node metastasis in patients with extramammary Paget’s disease. 相似文献
