Farbcodierte Dopplersonographie (FD-Sonographie) primärer und sekundärer Lebertumoren

2008

50 Patients with 78 focal liver lesions were examined via colour-coded Doppler system to study the vascularity of metastatic lesions and primary benign and malignant liver tumours. According to the amount of detectable colour Doppler signals, tumour vascularity was graded into 4 types. Metastases (n = 40) and cavernous haemangiomas (n = 12) seemed to be avascular with no evidence of increased vascularity (Type I/II). Conversely primary liver cancer (PLCA) (n = 7) and focal nodular hyperplasia (FNH) (n = 16) mainly produced arterial Doppler signals within the tumour (Type III/IV). AV shunts and partial portal vein thrombosis could be demonstrated in PLCA. Doppler colour flow imaging for dete…

Acquired elastotic hemangioma-like changes and eccrine sweat duct squamous metaplasia in lichen simplex chronicus/prurigo nodularis-like lesions of t…

2017

Background The so-called acquired elastotic hemangioma (AEH) represents a peculiar vascular lesion affecting the sun-damaged skin of the extensor surface of the forearms or the lateral aspect of the neck of middle-aged or elderly women. Methods This is a clinicopathological and immunohistochemical study of a series of 6 lesions located on the knee or elbow showing epithelial features of lichen simplex chronicus (LSC)/prurigo nodularis (PN) with a marked subepidermal vascular proliferation closely resembling AEH. Results Microscopically, all cases of cutaneous lesions showed epithelial features of LSC/PN, that is compact hyperkeratosis with focal parakeratosis, irregular acanthosis, prominen…

Primary biliary cirrhosis and hereditary hemorrhagic telangiectasia: When two rare diseases coexist

2013

Primary biliary cirrhosis is a slowly progressive cholestatic autoimmune liver disease that mainly affects middle- aged women with an estimated prevalence ranging from 6.7 to 402 cases per million. Hereditary hemorrhagic telangiectasia, or Rendu-Osler-Weber disease, is an autosomal dominant disorder characterized by angiodysplastic lesions (telangiectases and arteriovenous malformations) that can affect many organs, including liver, with a prevalence of 1-2 cases per 10000. We describe the coexistence, for the first time to our knowledge, of these two rare diseases in a 50-year old Caucasian woman. In this setting, the relevance of an accurate medical history, the role of liver histology an…

Variations in the size of focal nodular hyperplasia on magnetic resonance imaging

2013

Abstract Objective To evaluate the changes in the size of focal nodular hyperplasia (FNH) during long-term magnetic resonance imaging (MRI) follow-up. Material and methods We reviewed 44 FNHs in 30 patients studied with MRI with at least two MRI studies at least 12 months apart. We measured the largest diameter of the lesion (in mm) in contrast-enhanced axial images and calculated the percentage of variation as the difference between the maximum diameter in the follow-up and the maximum diameter in the initial study. We defined significant variation in size as variation greater than 20%. We also analyzed predisposing hormonal factors. Results The mean interval between the two imaging studie…

Assessment of prurigo of pregnancy in patients without atopic background

2020

Highlights • PP can develop in patients without atopic background. • Onset: late 2nd to early 3rd trimester; can persist until delivery. • Patient should be counseled accordingly. • These findings should be considered when classifying specific pregnancy dermatoses.

Problemi di conservazione delle camere ipogee in calcarenite nella Fossa della Garofala (Palermo)

2009

La Fossa della Garofala è una stretta valle chiusa da pareti subverticali, incisa dal Torrente Kemonia nella placca calcarenitica che costituisce il sottosuolo di Palermo. Il valore storico monumentale della valle risiede, oltre che nella significatività geologica e geomorfologica del sito, anche nella presenza di cavità ipogeiche artificiali utilizzate dal periodo punico fino al XIX sec. La conservazione nel tempo di questo significativo patrimonio culturale è minacciata da fenomeni di dissesto sempre più frequenti. Il lavoro presenta una caratterizzazione geologica e geotecnica dell’ammasso calcarenitico e propone indirizzi progettuali per gli interventi di consolidamento.

Benign liver lesions 2022: Guideline for clinical practice of Associazione Italiana Studio del Fegato (AISF), Società Italiana di Radiologia Medica e…

2022

Benign liver lesions are increasingly diagnosed in daily clinical practice due to the growing use of imaging techniques for the study of the abdomen in patients who have non-specific symptoms and do not have an increased risk of hepatic malignancy. They include simple or parasitic cysts and solid benign tumors which differ widely in terms of prevalence, clinical relevance, symptoms and natural history and often lead to significant clinical problems relating to diagnosis and clinical management. Following the need to have updated guidelines on the management of benign focal liver lesions, the Scientific Societies mainly involved in their management have promoted the drafting of a new dedicat…

Thyroid sarcoidosis as a unique localization.

2006

Sarcoidosis is a systemic disorder characterized by granulomatous lesions, principally affecting the lungs. There are numerous reports in the literature of an associated involvement of the thyroid, much more frequently in hypothyroid than in hyperthyroid subjects. The present case report refers to a woman presenting with thyroid nodules and normal biochemical levels and thyroid function parameters, while histology revealed sarcoid-type lesions. Subsequent investigations and a long follow-up showed no evidence of involvement of other sites, including the lungs. Consequently, after a long period of normal health associated with the negative results of the examinations, a diagnosis of sarcoido…

Comparison of Epidermal Barrier Integrity in Adults with Classic Atopic Dermatitis, Atopic Prurigo and Non-Atopic Prurigo Nodularis

2021

Simple Summary Atopic dermatitis, also called neurodermatitis, is one of the best-known chronic inflammatory skin diseases with eczema, strong itch and dry skin. It is based on an impaired skin barrier with changes in the fats and proteins of the horny layer, which leads to a disturbed water balance. Prurigo nodularis is a less common and intractable chronic skin disease with very itchy nodules. It can be associated with atopic dermatitis (so called atopic prurigo) or with many other diseases. The aim of this study was to compare these three skin diseases classic atopic dermatitis, atopic prurigo and non-atopic prurigo nodularis with healthy control subjects with regard to their skin barrie…
