Breast metastases as the first sign of recurrence of a cutaneous melanoma.

Malignant melanoma is the most rapidly increasing cancer in the world. Metastatic disease occurs in 20% of patients, and prognosis in these cases is poor. We report the case of a woman who presented breast metastasis as the first sign of recurrence of a melanoma.

CCND1- and ERBB2-gene deregulation and PTEN mutation analyses in invasive lobular carcinoma of the breast.

Because of the relatively low incidence of lobular breast carcinoma, there are very few studies on the molecular characteristics of this breast cancer. In an attempt to improve its characterization, we investigated in a large collection of invasive lobular carcinomas (ILCs) the status of markers known to be involved in the better-studied invasive ductal carcinomas (IDC). In the current study we disposed of 80 well-characterized ILC cases.
