Pancreatoblastoma associated with incomplete Beckwith-Wiedemann syndrome: case report and review of the literature.

A case of pancreatoblastoma (PB) in a 2 month-old male infant with incomplete Beckwith-Wiedemann syndrome is presented. Clinical examination disclosed left hemihypertrophy, macroglossia, bilateral exophthalmos, and enlargement of the left testis. Imaging with ultrasound and computed tomography scan showed a well-defined, heterogeneous, and grossly cystic mass arising from the head of the pancreas. Serum alpha-fetoprotein (AFP) level was elevated. The tumor was completely resected, and the histological analysis showed PB. The patient's recovery was uneventful, and AFP returned to normal values after surgery. The child has been disease-free for 5 years, and his serum AFP remained within normal values. Six other examples of this association, PB, and Beckwith-Wiedemann syndrome are recorded in the literature. The risk of developing tumor in this syndrome (complete and incomplete form) increases when hemihypertrophy is present, and the need for routine screening examination is warranted. Beckwith-Wiedemann syndrome was suggested to be a favorable biological marker for survival in children who have intraabdominal tumors.

[Predictive factors for malignancy in breast microcalcifications without associated lesions].

INTRODUCTION: Screening mammography allows the early detection and treatment of nonpalpable carcinomas. Microcalcifications are highly important for the detection of many of these malignancies but are also present in benign breast disease. In the present study we analyzed the radiologic and clinical factors associated with malignancy. MATERIAL AND METHODS: We retrospectively reviewed 133 patients who underwent open biopsy after a mammographic finding of microcalcifications without an associated lesion. Clinical and radiologic characteristics were correlated with histologic findings. RESULTS: A total of 28.6% of the lesions analyzed were malignant. Of these, 65.8% were ductal carcinoma in situ. Among invasive carcinomas, 23.1% presented lymph node metastasis. No clinical criterion was significant for malignancy. On univariate analysis six radiologic criteria were significant: morphologic type (Le Gal's classification), irregularity of size, irregularity of density, number of microcalcifications per cluster, diameter of the lesion, and the presence of more than one cluster. On multivariate analysis the factors with independent predictive value were: irregularity of density, > or = 10 microcalcifications per cluster, the presence of more than one cluster, and diameter of the cluster > or = 10 mm. CONCLUSIONS: Although none of the clinical factors analyzed was predictive for malignancy, the radiological characteristics of microcalcifications were determining factors in the indication for biopsy.
