Breast lumps have diverse causes including benign as well as malignant lesions. Fibroadenoma (FA) is a common cause of breast lump. Complex fibroadenomas, a particular subtype, pose diagnostic dilemmas due to confusing the radiological findings and hold higher incidence of transformation to malignancy. A 49 year old female presented with a painless lump in right breast for 2 years which appeared calcified on radiology. Excision biopsy was performed which grossly revealed an encapsulated grey-white firm to hard with cystic areas. Microscopically the sections showed a well encapsulated fibroepithelial tumor showing areas of sclerosing adenosis, hyalinization, cysts lined by cuboidal cells with eosinophilic secretions, areas of calcification and ossification. No evidence of lobular hyperplasia or in-situ carcinoma was seen. Patient was advised follow up. This case represents the unusual occurrence of complex fibroadenoma in a middle-aged female showing with ossification.

The Authors present their experience with TUR plus adjuvant intravesical chemotherapy in 50 patients affected by primary T1 G3 bladder tumours without previous or concomitant carcinoma in situ. At a mean follow-up of 36 months, 84% of the patients are alive and tumour-free. Cystectomy was performed in three patients due to locally invasive disease. Five patients (10%) died of bladder cancer.

Increased Risk

10510 Background: Although it is well established that preneoplastic lesions are associated with an increased risk of breast cancer, there is no available tool to identify which patients will develop breast cancer. Telomerase, matrix metalloprotease 1 (MMP1) and Her2 have all been involved in the early steps of carcinogenesis. In the present study, we have looked at whether the expression of hTert, MMP1 and her2 in preneoplastic lesions were associated with higher risk of breast cancer. Methods: hTert, MMP1 and Her2 expressions by preneoplastic lesions were determined by immunohistochemistry in 34 patients who have subsequently developed a breast cancer (cases), and in 32 patients who did not present breast cancer in the follow-up (control). Patients were matched for age, length of follow-up and type of preneoplastic lesion. The expression of the three biomarkers was compared in the two groups. The initially planned sample size of the study was 90 matched patients, but only 66 samples could be proceed for technical reasons. Results: Median age was 47 and 49 years old in patients with and without further cancer respectively. In the group of patients who subsequently developed breast cancer (cases), preneoplastic lesions consisted in lobular hyperplasia or lobular in situ carcinoma in 17 cases, ductal atypical hyperplasia in 12 cases and mixed lesions in 5 cases. In the control group, preneoplastic lesions consisted in lobular hyperplasia or lobular in situ carcinoma in 18 cases, ductal atypical hyperplasia in 12 cases, mixed lesions in 2 cases. The median interval between the diagnosis of preneoplastic lesion and the occurrence of breast cancer was 72 months (17–291). hTert was expressed in 8 (27%) and 2 (7%) assessable lesions in cases and controls respectively (p = 0.04). MMP1 was expressed in 21 (65%) and 22 (73%) assessable lesions in cases and control respectively (p = 0.49). Her2 was expressed in 6 preneoplastic lesions both in cases and controls (20%). Conclusions: This study suggests that hTert expression by preneoplastic lesions could be associated with an increased risk breast cancer. No significant financial relationships to disclose.

e21025 Background: In OD and OA, the 1p and 19q deletion has prognostic value in survival. It is also a predictive factor for response to chemotherapy. Fluorescence in situ hybridization (FISH) is the standard method for its evaluation. CISH could be an alternative that has already been validated in other neoplasias. In OD and OA, this combined deletion is present in about 50% of patients when analyzed with FISH. Methods: Patients resected at Clinica Reina Fabiola from january 2006 to january 2010 and diagnosed of OD and OA were propectivelly included. Paraffin-embebed tumor tissue was analyzed for 1p19q deletions by CISH. The results were correlated to the histology (OD and OA) and grade (II and III) of the tumors. Results: The demographic features of the patients from the present study coincide with literature. The 1p and 19q deletion was found in 3 of the 24 patients analyzed (13%). The combined deletion was only found in those with grade II OD. No combined deletion was found in patients diagnosed of grade III OD and grade II and III OA. In the subgroup of patients with grade II OD, the combined deletion was observed in 3 of 11 patients (27%). The 3 patients in which the deletion in both chromosomes was observed, received treatment with chemotherapy and radiotherapy, all of them with complete response. 5 years DFS was 90%-median follow up 36,8 (CI: 30,5-42,98) Conclusions: The detection of the combined deletion with CISH technique was inferior (13%) than the literature. We cannot demonstrate that CISH is a reliable method for the detection of the 1p and 19q deletion. The possible reasons of this difference could be attributed to the number of patients of the study, to deviations in the procedures of the test or to the fact that the CISH method is not coincident with FISH. This prospectivelly monoinstitutional results are also different to our previous report, and may be due to different pathological evaluation.

<b><i>Introduction:</i></b> Non-epithelial primary mammary osteosarcomas are extremely rare. The differentials include metaplastic carcinoma and malignant phyllodes tumour. This is the first published case of primary breast osteosarcoma arising after local radiotherapy. <b><i>Case Presentation:</i></b> A 73-year-old female presented with a right-sided breast lump. The same breast had been irradiated 11 years previously for invasive ductal carcinoma. Diagnostic excision revealed a highly cellular, malignant spindle-cell lesion merged with an osteoid matrix and foci of calcification and bone formation. Immunohistochemistry and molecular studies showed no lines of differentiation. Due to the lack of epithelial/glandular differentiation, in situ carcinoma or leaf-like pattern, the diagnosis of post-irradiation osteosarcoma was made. She underwent mastectomy and is disease-free at 8 months of follow-up. <b><i>Conclusion:</i></b> Post-irradiation osteosarcoma should be considered in the differential diagnosis of breast lesions showing malignant osteoid. Extensive sampling and careful search for epithelial differentiation is required to guide management. Complete surgical excision is recommended.

During the follow-up of a woman treated by radiotherapy for an in situ carcinoma of her left breast, radio-induced skin lesions were diagnosed. They appeared not to be simple radiodermatitis but radio-induced Sweet syndrome. Discussions were led on the benefit of completing the last session of radiotherapy for such a low-grade malignancy while considering the risk of complication from radio-induced disease. General and local corticotherapy rapidly eradicated the fever and asthenia, while the skin lesions disappeared gradually. Moreover, biological improvement was noticed. The presented features of Sweet syndrome are almost similar in their initial phase to the radiodermatitis that is seen in common medical conditions.
