Radiation induced esophageal adenocarcinoma in a woman previously treated for breast cancer and renal cell carcinoma

BACKGROUND: Secondary radiation-induced cancers are rare but well-documented as long-term side effects of radiation in large populations of breast cancer survivors. Multiple neoplasms are rare. We report a case of esophageal adenocarcinoma in a patient treated previously for breast cancer and clear cell carcinoma of the kidney. CASE PRESENTATION: A 56 year-old non smoking woman, with no alcohol intake and no familial history of cancer; followed in the National Institute of Oncology of Rabat Morocco since 1999 for breast carcinoma, presented on consultation on January 2011 with dysphagia. Breast cancer was treated with modified radical mastectomy, 6 courses of chemotherapy based on CMF regimen and radiotherapy to breast, inner mammary chain and to pelvis as castration. Less than a year later, a renal right mass was discovered incidentally. Enlarged nephrectomy realized and showed renal cell carcinoma. A local and metastatic breast cancer recurrence occurred in 2007. Patient had 2 lines of chemotherapy and 2 lines of hormonotherapy with Letrozole and Tamoxifen assuring a stable disease. On January 2011, the patient presented dysphagia. Oesogastric endoscopy showed middle esophagus stenosing mass. Biopsy revealed adenocarcinoma. No evidence of metastasis was noticed on computed tomography and breast disease was controlled. Palliative brachytherapy to esophagus was delivered. Patient presented dysphagia due to progressive disease 4 months later. Jejunostomy was proposed but the patient refused any treatment. She died on July 2011. CONCLUSION: We present here a multiple neoplasm in a patient with no known family history of cancers. Esophageal carcinoma is most likely induced by radiation. However the presence of a third malignancy suggests the presence of genetic disorders

Malignant Peripheral Nerve Sheath Tumor of the Small Bowel: An Unusual Presentation with Fatal Outcome

Malignant peripheral nerve sheath tumor of the small bowel is an extremely rare disease. Histologic distinction from other types of soft tissue sarcoma especially fibrosarcoma and leiomyosarcoma requires electron microscopy. Complete surgery remains the only curative treatment. However, late diagnosis makes curative surgery more difficult. The contribution of chemotherapy to incomplete surgery has been proved without controlled studies. We report a case of this type of lesion discovered following a small bowel perforation

AMIFT: AFFINE-MIRROR INVARIANT FEATURE TRANSFORM

International audienceIn this paper, we propose a descriptor for image matching under multiple mirror reflections. Indeed, existing adaptations of SIFT for the mirror transformation are not successful when object and mirrors orientations are not constrained. Hence, we propose to combine MIFT and Affine-SIFT descriptors as the Affine Mirror Invariant Feature Transform (AMIFT). The experimental results and given evaluation show that our proposed descriptor outperforms MIFT and ASIFT on both synthetic and real images datasets

Reconstruction 3D d'objet à partir d'une image catadioptrique multi-plan

International audienceL'étude porte sur un Système Stéréo Catadioptrique multiPlan (SSCP) constitué d'une unique caméra perspective et deux miroirs plans judicieusement positionnés. En positionnant un objet entre les miroirs plans et la caméra, cinq vues en sont observées simultanément. Dans cet article, nous abordons la modélisation et l'étalonnage géométrique de SSCP. Les points d'intérêt détectés dans la vue directe servent de référence pour la recherche de correspondances sous la contrainte d'une homographie minimisant l'erreur photométrique entre voisinages. La correspondance mène à la reconstruction 3D des points dont les résultats démontrent la qualité de la méthode de recherche de correspondances et que la reconstruction 3D avec une image d'un SSCP est possible

Successful Management of Metastatic Eccrine Porocarcinoma

Eccrine porocarcinoma (EPC) is a rare tumor. It develops from the intraepidermal ductal portion of the eccrine sweat gland. Metastatic disease is rare. We report a new case of metastatic eccrine porocarcinoma with a successful management and a good response to docetaxel. A 54-year-old man was admitted with a mass in the breast. Biopsy specimen found carcinomatous tumor proliferation with large anastomosing ducts. Cellular atypia were noted, with eosinophilic cytoplasm and round to oval nuclei. The tumor showed positive immunoreactivity for ACE and negative to anti-PS-100. Resection was performed. One year later, he presented with local and metastatic recurrences. The patient had received 3 cycles of cisplatin and 5-fluorouracil; he progressed with increase in mass size and number of lung lesions. He has been undergoing three cycles of docetaxel with complete response in the lung and regression of the breast mass. The mass was excised. Porocarcinoma is a very rare entity and poorly understood. In the metastatic phase, it has modest or no sensitivity to anticancer treatment. Docetaxel should be considered in the metastatic eccrine porocarcinoma
