Transient hepatic nodular lesions associated with patent ductus venosus in preterm infants.
2010
We report on two cases of low-birth-weight preterm infants with patent ductus venosus associated with hepatic hypoechoic lesions of the fourth segment in an otherwise normal liver. Although tumorlike hepatic lesions have been previously reported in association with portosystemic shunts in children and adults, they were never described in preterm infants during physiological patency of ductus venosus. In our patients, hepatic lesions disappeared shortly after the spontaneous ductus closure. Physiopathologic interactions are discussed regarding altered portal blood supply caused by ductus venosus shunt.
Association between Hashimoto's thyroiditis and papillary thyroid carcinoma: A retrospective analysis of 305 patients
2019
Abstract Background The association between Hashimoto’s thyroiditis (HT) and papillary thyroid carcinoma (PTC) is a controversial question that is still under debate, its pathological significance and the eventual clinical implications of this association remaining unclear. Methods The data regarding 305 patients were retrospectively analyzed. The patients were divided in two different groups. A first group made up of 142 patients undergoing surgery for differentiated thyroid carcinoma was compared to a control group of 142 analogous subjects operated for normofunctioning goiter. A second group was made up of 163 patients who had undergone total thyroidectomy (TT) with pre-operative diagnos…
Angioleiomyoma affecting the lips : report of 3 cases and review of the literature
2010
Angioleiomyoma is an uncommon benign soft tissue tumor usually found in the lower extremities and rarely observed in oral tissues. It is microscopically characterized as a proliferation of smooth muscle cells intermingled with abundant vascular channels. Oral angioleiomyomas affect mostly the lips, palate, buccal mucosa and tongue, and appears as a submucosal painless nodule. Upper lip is seldom affected and only few cases have been reported. We report three additional cases of angioleiomyoma affecting the lips of elderly patients. All lesions were asymptomatic and presented as submucosal nodules of approximately 1cm. Microscopic analysis on H and E sections revealed similar pattern in all …
