A 54-year-old-woman who underwent augmentation mammoplasty with silicone gel implants 30 years previously, visited our hospital with complaints of bloody nipple discharge, redness and itching of her right breast. Cancer of the right breast was diagnosed by dynamic magnetic resonance imaging (MRI) examination with Gadolinium (Gd)-DTPA enhancement. Radical mastectomy was subsequently performed. The histopathological findings demonstrated scirrhous and inflammatory breast cancer with invasion of dermal lymphatics.
We describe a 20-year-old woman with trisomy 18 mosaicism, who presented with skeletal anomalies, epilepsy, mental retardation, and linear and whorled naevoid hypermelanosis.
A 36-year-old woman presented with a 10 mm diameter mass in the right breast. Since the mass persisted for 3 months after detection and mammary carcinoma was suspected based on ultrasonographic findings, the mass was resected. Histologically, the mass demonstrated proliferative margins and consisted of spindle cells with bland cytologic features and abundant collagen. Immunohistochemically, the spindle cells were positive for vimentin and smooth muscle actin, and were negative for cytokeratins and desmin. Furthermore, the cells showed MIB-1 immunoreactivity with a MIB-1 labeling index of 4.1. Based on these findings, was diagnosed fibromatosis. Breast fibromatosis is rare and is usually misdiagnosed as breast carcinoma preoperatively. To date, only 10 cases of breast fibromatosis have been reported in Japan. Among the reported cases in Japan, our patient presented with the smallest mass, and ultrasonographic findings in this case were the same as those of other cases. Our experience and a review of the literature indicated that differentiation of fibromatosis from carcinoma is very difficult by ultrasonographic examination. In our case, despite involvement of the surgical margins, there was no recurrence. This may be attributed to the small size of the mass and focal exposure.
Background: Bilateral male breast cancer (MBC) is relatively rare. Case Reports: We report 2 bilateral nonsynchronous MBC cases. Second cancers developed during endocrine therapy with selective estrogen receptor modulators (SERM) after the initial surgeries. Since their second surgeries, both patients continued treatment with another SERM, because their second cancers were also hormone receptor-positive. We discuss the endocrine therapy in men based on a review of the literature. Conclusions: Adequate treatments for early MBC are still controversial. Aromatase inhibitors (AI) are not as effective in men as in women. We consider the higher androgen levels in men to be a major reason for AI not being as effective as expected, i.e. the hormonal environment is very different from that in women. Thus, different approaches are needed for MBC. With further investigation, it is hoped that methods of achieving maximal AI efficacy for MBC will be established.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
