Background: Paget's disease (PD) is a rare form of intraepithelial adenocarcinoma that involves breast and extramammarian tissues. It is often associated with ductal carcinoma in situ and/or invasive ductal cancer. Molecular pathways that play a role in development of Paget's disease are stil unclear. Expression patterns of Cox-2 and bcl-2 were therefore assessed. Materials and Methods: Patients with a histopathological diagnosis of Paget's disease were included in this study. Patient files were analysed retrospectively. Results: Invasive cancer was diagnosed in 35 (76.1%) of the patients, 7 (15.2%) had ductal carcinoma in situ and 4 (8.7%) patients had no associated neoplasm. Twenty four (52.2%) patients showed COX-2 expression in Paget cells whereas no expression was seen in 22 (47.8%) patients. No relation was found between COX-2 expression and the lesion underlying Paget's disease (p=0.518). Bcl-2 expression in Paget cells was found positive in 12 (26.1%) and negative in 27 (58,7%) cases. There was no relation between Bcl-2 expression and the lesion accompanying Paget's disease (p=0.412). No relation was observed between COX-2 expression and Bcl-2 expression (p=0.389). Conclusions: In breast cancer, COX-2 expression is associated with poor prognostic factors. As COX-2 expression increases the tendency to metastasize also increases. In our study we found a significantly high COX-2 expression in Paget's disease of the breast. We suggest that COX-2 expression and inflammatory processes may play a role in pathogenesis of the Paget's disease of the breast.

Mammary Paget's disease (MPD) is usually accompanied by underlying breast malignancy; however, a few cases have been reported as only skin lesions without any evidence of malignancy of the breast on imaging tests and microscopic examination of surgical specimen. Here, we describe a 47-year-old woman who visited our hospital who had an eczematous lesion on right nipple and areola for over 10 years. The lesion was diagnosed as Paget's disease by punch biopsy; however, imaging studies demonstrated no breast malignancy or lymph node metastasis. The patient underwent surgery of on the nipple and areola including underlying breast tissue. No underlying malignancy was found upon microscopic examination, except for Paget's disease. Immunohistochemical stains revealed that the tumor cells were positive for cytokeratin 7, and negativity for p63, cytokeratin 5/6, estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2. We report a case of MPD without underlying malignancy. To the best of our knowledge, this is the third case reported in Korea.

Purpose: Penoscrotal extramammary Paget's disease is a rare cutaneous malignancy that primarily affects the elderly. To prevent local recurrence, adequate surgical excision with its intraoperative frozen section, proper reconstruction, and careful follow-ups are required. The present study describes the treatment of patients with penoscrotal extramammary Paget's disease, focusing on the reconstruction after the ablation of lesion. Methods: Nine patients were selected who had undergone a local pedicle flap procedure due to the large defects after ablation of extramammary Paget's disease of the penoscrotal area, during the period of 1999 to 2005. Wide excision combined with intraoperative frozen sectioning was performed, and the penoscrotal wound was reconstructed with a local skin flap. Three flaps were chosen depending on the size of the defect. If the defect size was small and the scrotal tissue was adequate, scrotal flap(n=5) was enough for its reconstruction. However, as there were large defects with insufficient remnant scrotal tissue, a groin flap(n=2) or an anterolateral thigh flap(n=2) were performed. Results: There were no complications with the postoperative wound. Furthermore, no local recurrence was noted during two to six years of follow-up period (mean average 3.7 years). Conclusion: For the resurfacing the penoscrotum at large defects after ablation of extramammary Paget's disease, we performed reconstruction with a local flap. In the aspect of both function and cosmetic concerns, the results were satisfactory.

Extramammary Paget's disease is uncommon intraepithelial carcinoma of the skin and frequently associated with a subjacent or a regionally proximate carcinoma. We have experienced a case of extramammary Paget's disease affecting 71 year-old man. The patient has been suffered from a well demarcated, and slowly growing erythematous plaque on the left suprapubic area for 3 years. A biopsy specimen reveals infiltration of typical Paget's cells within the epidermis and the adnexa. We review the literature briefly.

Extramammary Paget disease (EMPD) is an uncommon malignancy that occurs in apocrine gland-rich areas of the body. EMPD of the axilla is rare, but a few cases have been reported. Some cases of EMPD have been reported with underlying apocrine adenocarcinoma; rarely, mammary-type ductal carcinoma can accompany EMPD. Here, we report a very rare case of EMPD with apocrine adenocarcinoma and invasive mammary-type ductal carcinoma. A 55-year-old woman was referred with a brownish pigmented plaque accompanying an area of ulceration in the left axilla. A preoperative biopsy indicated Paget disease, and an additional evaluation was performed to determine whether it was of primary or secondary origin. A wide excision was made, and the axilla was reconstructed using a thoracodorsal artery perforator flap. The biopsy showed apocrine adenocarcinoma and invasive mammary-type ductal carcinoma with pagetoid spreading. The patient had no evidence of recurrence or other postoperative complications.

Extramammary Paget disease (EMPD) is a rare disease, especially in Asian populations. Surgical resection is considered the primary treatment option. Recently, radiotherapy has been suggested as an EMPD treatment, either as an alternative to surgical resection or in combination with surgical resection. This report reviewed a patient with EMPD who was treated with wide excision of the EMPD site followed by radiotherapy for remaining gross lymph node metastases. The aim of this report was to determine the optimal treatment for advanced EMPD.

Ultrasound (US) is an attractive diagnostic approach to identify both common and uncommon nipple pathologies, such as duct ectasia, nipple abscess, nipple leiomyoma, nipple adenoma, fibroepithelial polyp, ductal carcinoma in situ (restricted to nipple), invasive carcinoma, and Paget's disease. US is the reliable first-line imaging technique to assess nipple pathologies. It is useful to identify and characterize nipple lesions. Additionally, we have presented the mammography and MRI outcomes correlated with histopathologic features for the relevant cases.

Background Extramammary Paget's disease (EMPD) is an intraepithelial carcinoma usually occurring on the skin or mucosa of the perineum. Clinically, it resembles eczema or dermatitis, and misdiagnosis and treatment delays are common. The treatment of choice for EMPD is a wide excision with adequate margins. Wide excision with intraoperative frozen biopsy and Mohs micrographic surgery are common methods; however, these are associated with a high recurrence rate and long operation time, respectively. Methods Between January 2010 and June 2013, 21 patients diagnosed with EMPD underwent mapping biopsy. Biopsy specimens were collected from at least 10 areas, 2 cm from the tumor margin. When the specimens were positive for malignancy, additional mapping biopsy was performed around the biopsy site of the positive result, and continued until no cancer cells were found. Based on the results, excision margins and reconstruction plans were established preoperatively. Results The patients (18 male, 3 female) had a mean age of 66.5 years (range, 50-82 years). Almost all cases involved in the perineal area, except one case of axillary involvement. Permanent biopsy revealed one case (4.8%) of positive cancer cells on the resection margin, in which additional mapping biopsy and re-operation was performed. At the latest follow-up (mean, 27.4 months; range, 12-53 months), recurrence had not occurred. Conclusions Preoperative mapping biopsy enables accurate resection margins and a preoperative reconstructing plan. Additionally, it reduces the operation time and risk of recurrence. Accordingly, it represents an effective alternative to Mohs micrographic surgery and wide excision with intraoperative frozen biopsy.

The aim of this study was to detail characteristics of mammary Paget's disease (PD) representing the whole population in China. A total of 4211 female breast cancer inpatients at seven tertiary hospitals from seven representative geographical regions of China were collected randomly during 1999 to 2008. Data for demography, risk factors, diagnostic imaging test, physical examination and pathologic characters were surveyed and biomarker status was tested by immunohistochemistry. The differences of demography and risk factors between PD with breast cancer and other lesions were compared using Chi-square test or t-test, with attention to physical examination and pathological characters. The percentage of PD was 1.6% (68/4211) in all breast cancers. The mean age at diagnosis was 48.1, and 63.2% (43/68) patients were premenopausal. There is no difference in demography and risk factors between PD with breast cancer and other breast cancer (P > 0.05). The main pattern of PD in physical exam and pathologic pattern were patients presenting with a palpable mass in breast (65/68, 95.6%) and PD with underlying invasive cancer (82.4%, 56/68) respectively. The rate of multifocal disease was 7.4% (5/68). PD with invasive breast cancer showed larger tumor size, more multifocal disease, lower ER and PR expression and higher HER2 overexpression than those in other invasive breast cancer (P < 0.05). These results suggested that PD in China is a concomitant disease of breast cancer, and that PD with underlying invasive cancer has more multiple foci and more aggressive behavior compared with other breast invasive cancer. We address the urgent needs for establishing diagnostic and therapeutic guidelines for mammary PD in China.
