RESUMEN
OBJECTIVE: To examine factors that affect the positive surgical margins of facial basal cell carcinoma (BCC) and investigate whether the surgical margin value can be narrowed in early-stage facial BCCs. METHODS: Ninety-five patients were divided into the three groups based on prognosis: good (n = 48), mixed (n = 32), and poor (n = 15). The good prognosis group (group 1) included nodular and superficial subtypes; the mixed prognosis group (group 2) included nodular-infiltrative, nodular-micronodular, and nodular-sclerosing subtypes; and the poor prognosis group (group 3) included infiltrative and micronodular subtypes. RESULTS: Groups 1 and 2 differed from each other significantly in terms of positive surgical margin (P = .002) and tumor thickness (P = .008), but group 3 did not (P = .851 and P = .804, respectively). With regard to surgical method (primary vs local flap repair), only tumor localization varied significantly (P < .001). CONCLUSIONS: Groups differed significantly in terms of surgical margin positivity, the distance of the tumor to the surgical margin, and the tumor thickness. The intact surgical margin was 2 mm on average in this study, and the authors suggest that it may be possible to revise the surgical margin values recommended in the literature.

Skeletal dysplasias (SDs) constitute a group of heterogeneous disorders affecting growth morphology of the chondro-osseous tissues. Prenatal diagnosis of SD is a considerable clinical challenge due to phenotypic variability. We performed a retrospective analysis of the fetal autopsies series conducted between January 2006 and December 2012 at our center. SD was detected in 54 (10%) out of 542 fetal autopsy cases which included; 11.1% thanatophoric dysplasia (n = 6), 7.4% achondroplasia (n = 4), 3.7% osteogenesis imperfect (n = 2), 1.9% Jarcho-Levin Syndrome (n = 1), 1.9% arthrogryposis (n = 1), 1.9% Dyggve-Melchior-Clausen syndrome (n = 1), 72.1% of dysostosis cases (n = 39). All SD cases were diagnosed by ultrasonography. In 20 of the cases, amniocentesis was performed, 4 cases underwent molecular genetic analyses. Antenatal identification of dysplasia is important in the management of pregnancy and in genetic counseling. Our data analysis showed that SD is usually detected clinically after the 20th gestational week. Genetic analyses for SD may provide early diagnosis and management.

Congenital pulmonary lymphangiectasia (CPL) is a rare congenital disorder that typically presents with intractable respiratory failure in the first few days of life. There is an association non-immun hydrops and CPL. In this study we reviewed four CPL cases between January 2006 and January 2014 among 684 fetal-pediatric autopsies. All cases were in the second trimester. In light microscopy there were marked dilatated channels in the subpleural -peribronchial-subseptal region of the lungs. The channels were lined with flattened cells which were expressing CD 31 and D2-40, negative for CD34. Although pulmonary interstitial emphysema (PIE) was considered an important differential diagnosis, a giant cell reaction surrounding the interstitial cystic lesions, a histological hallmark of PIE. CPL is characterized by dilatation of the pulmonary lymphatic vessels and occurs as a congenital anomaly. Noonan classified it into three groups. Primary developmental defect of pulmonary lymphatics is group 3. Group 3 is called also as CPL; normal regression of the connective tissue elements fails to occur after the 16th week of fetal life, associated with an aggressive clinical course, poor prognosis. In fetal autopsy examination CPL should be recognized if there is a fetus with pleural effusion, non-immune hydrops. There is no clinical evidence for CPL.
