Mutations in the p53 tumor suppressor gene are present in approximately 50% of all human cancers. We sought to determine the frequency and type of p53 mutations in squamous cell carcinomas (SCC) of the oral cavity in a Brazilian population. To identify p53 mutations we used PCR-SSCP in tumor tissue microdissected from paraffin- embedded and from(More)

At the moment of the diagnosis, the mothers are asymptomatic in 40 to 60% of cases. The most common manifestations are cutaneous lesions and congenital heart block. The cutaneous(More)
Patients with large congenital melanocytic nevus (LCMN) have a high risk of developing malignant melanoma (MM) and other malignancies. We report a case of a mesenchymal malignancy that best fit the diagnosis of a malignant peripheral nerve sheath tumor and subsequent development of a MM developing from a LCMN. There are no previous reports of a second(More)

Giant cell tumor of the tendon sheath is a benign soft tissue tumor most frequent between the third and fifth decades of life. It can mimic and make differential diagnoses with several hand tumors. Definitive diagnosis and the treatment of choice are reached with complete resection and histopathological examination. Here we describe a case with clinical(More)
