Microscopic polyangiitis (MPA) is a systemic small vessel vasculitis that is included in the pulmonary-renal syndromes. Although glomerulonephritis represents the major clinical feature of MPA indicative of renal involvement, diffuse alveolar haemorrhage is the classic manifestation of pulmonary involvement. However, pulmonary fibrosis is a less frequently reported pulmonary manifestation. Herein we describe a patient who was diagnosed with MPA presenting with radiographic evidence of pulmonary interstitial fibrosis as an early clinical manifestation accompanied by constitutional symptoms such as fever and weight loss. We also include a short literature review focusing on the association between pulmonary fibrosis and MPA.
Objectives: Fetal lymphangiomas are uncommon congenital malformations of the lymphatic system that involve the skin and subcutaneous tissues. Lymphangiomas can occur anywhere in the skin and the mucous membranes.The aim of this study was to review the ultrasound findings in the prenatal diagnosis, the outcome and treatment of the NNL. Methods: We analyze our database with 1843 cases of congenital anomalies between 2003 to March of 2012. The definition for the prenatal diagnosis of the Lynphangiomas were cystic mass who involve the without vascular supply and include in the soft tissue. We exclude the nuchal localization. The diagnosis was confirmed after birth and each one was follow. The variables include in the analysis were the localization, associate malformations, postnatal outcome, treatment. Results: Thirteen cases were diagnosed with NNL. Postnatal assessment was obtained in all the cases. The anatomic localization was: fetal thorax 2 cases, axillar 3 cases, facial 2 cases, anterior neck 3 cases; 1 of them with a big mass with obstruction of the air way, arm 1 case, gluteus 1 case an 1 case with lymphangiomatosis. 2 (15%) died in the perinatal period 1 of them the lymfangiomatosis and the other the anterior neck with air way obstruction. 2 (15%) of the cases had spontaneous resolution the localization of this cases was arm and 1 case in the anterior neck. 9 cases require postnatal treatment with medical therapy with Bleomicin and surgical reduction. None were associated with chromosomal anomalies. None of them produced functional limitation. The facial lynphangiomas were related with aesthetic facial scarring sequelae. Conclusions: The prenatal diagnosis of the NNL require a sequential analysis of the localization, size, multiloculation and mass effect. The Involvement of the upper airways one of the prognostic factor the prenatal diagnosis allows the preparation for birth. In cases of lymphangiomatosis the prognosis is poor. As to its other locations lymphangiomas the prognosis are well but the the sequelae commitment to aesthetic or function must be taken into account when counseling parents.
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.
