[Fibrosarcoma after silicone breast augmentation: is there a connection?].

We describe a 42-year-old woman in whom bilateral fibrosarcoma of the breast was diagnosed 15 years after bilateral breast augmentation with silicone implants. 3 years prior to admission the implants were replaced and 2 years prior to admission mammography showed a nodule in the left breast which biopsy showed to be fibrosarcoma. The implants were removed from both breasts and she was given chemotherapy but later that year underwent bilateral mastectomy. Despite chemotherapy, as well as adjuvant radiotherapy, the disease progressed, with involvement of the lungs and the skin of the left hemithorax. She was admitted repeatedly for severe anemia caused by bleeding from the malignant skin lesions, and died less than 2 years after diagnosis of the disease. Not all reports in the literature find a significant connection between silicone implants and subsequent development of breast cancer, but there are reports that do connect them. Breast fibrosarcoma is not significantly more frequent after silicone augmentation, but still there is controversy as to whether there is a connection between silicone implants and breast malignancy. In the patient we present, the prolonged exposure to silicone may have been a predisposing factor for the development of bilateral fibrosarcoma, since other known risk factors for breast cancer were denied.

Pseudotumor cerebri in systemic lupus erythematosus.

OBJECTIVE: To assess the association between pseudotumor cerebri (PC) and systemic lupus erythematosus (SLE), and to seek a pathogenic mechanism that may elucidate the appearance of PC in patients with SLE. DATA SOURCE: Original English articles having the terms SLE, PC, or benign intracranial hypertension in their titles were identified by Medline search. In addition we report three new patients with this association. STUDY SYNTHESIS: Thirteen articles were found and 21 patients were analyzed. DATA EXTRACTION: Of the reported 21 patients, 18 were previously reported and 3 new patients with coexisting PC and SLE are described. The clinical characteristics of the patients is presented. Patients with PC and SLE generally had a more severe course of SLE; renal involvement occurred in 79%, massive proteinuria in 47%, and hematologic abnormalities were detected in a third. A hypercoagulable state manifest by either recurrent thromboembolic events or a high anti-cardiolipin antibody titer was detected in 58% of the patients described. CONCLUSIONS: The association of PC and SLE is probably not coincidental. The high prevalence of serologic or clinical evidence of a hypercoagulable state suggests that microscopical thromboembolic events play a role in the genesis of PC.
