Surgical Treatment on Subungual Osteochondromas in Paediatric Feet: A Case Series Study

2020

Subungual osteochondroma (SO) is an infrequent and non-malignant bone tumour of the distal phalanx, especially prominent in paediatric populations. The aim of this research was to describe a case series of paediatric feet with SO which received surgical treatments. The secondary purpose was to compare these descriptive data by sex distribution. Methods: Twenty-three paediatric feet with SO confirmed by clinical or radiological features received surgical treatment. Socio-demographic (age, sex, height, weight and BMI) and clinical features (side, location, tumour or pain presence, and nail lift before surgery, as well as recurrence and adverse effects at one month after intervention) were rep…

Percezione del funzionamento familiare e strategie di coping in madri di bambini affetti da neoplasia in fase trattamentale

2013

Il contributo presenta uno studio correlazionale sul rapporto tra specifiche strategie di coping di madri di bambini con neoplasia in fase trattamentale e la loro percezione del funzionamento familiare, in termini di coesione e adattabilita/flessibilita, muovendo dall’ipotesi che una relazione "virtuosa" tra le variabili considerate possa costituire una risorsa importante per la madre. Lo studio, che ha coinvolto un gruppo di 34 madri di bambini con neoplasia in fase di trattamento, ha previsto la somministrazione di due specifici strumenti: il Coping Orientation to the Problems Experienced -Nuova Versione Italiana (COPE-NVI), per rilevare le strategie di coping, e il Family Adaptability an…

Squamous odontogenic tumor-like proliferation in a radicular cyst: a case report

2013

The squamous odontogenic tumour is a rare benign neoplasm whose aetiology remains unknown. It usually appears in the jaw and its origin could be related to the ephitelial remnants of Malassez. Histologically comprises numerous islets of squamous, non-keratinized, well-differentiated and rounded epithelial cells a fibrous stroma without signs of atypical cells. There is a non-neoplastic lesion with the same histological pattern than the squamous odontogenic tumour. This entity is characterized by squamous odontogenic tumour proliferations isolated into the cyst wall of an odontogenic cyst. It is rare and has a benign behavior. It has been suggested that these epithelial proliferations could …

Aetiology of Kidney Tumours

1983

Surveys of possible aetiological factors were made by one of us in 1963 and in 1967 (1,2), reviewing 441 articles hoping to find some clues to the causes of tumours of the kidney.

Odontogenic tumours: A review of 266 cases.

2012

Objectives: The aim of this study was to examine the relative frequency of odontogenic tumours at a tertiary hospital in Ibadan, as well as to study the various histologic types based on WHO 2005 classification and to compare results from this study with those of previous studies. Study design: The records of the Oral Pathology Department of University College Hospital were reviewed. Lesions diagnosed as odontogenic tumours were categorized into four groups based on WHO 2005 classification and were analyzed for age, sex and site using SPSS for Window (version 18.0; SPSS Inc. Chicago, IL) and frequency tables were generated. Results: Two hundred and sixty six (41.7%) cases of odontogenic tum…

Metallothionein immunoexpression in non-syndromic and syndromic keratocystic odontogenic tumour

2015

Background To compare the metallothionein (MT) immunoexpression in non-syndromic and syndromic keratocystic odontogenic tumour (KOT), to correlate MT with cellular proliferation, and to evaluate the influence of inflammation in MT. Material and Methods Fourteen cases of KOT were submitted to immunohistochemistry for MT and Ki-67 analysis. The lesions were grouped according to their grade of inflammation, and statistical analysis was performed. Results MT was higher in non-syndromic KOT than in syndromic KOT (p<0.05). No statistical difference in Ki-67 could be identified; however, an inverse correlation was observed between MT and Ki-67 in both lesions. When analysing inflammation, non-synd…

Tumor del estroma gastrointestinal y schwannoma gástricos: una presentación inusual en un paciente sin neurofibromatosis

2020

The majority of gastric neoplasms are of epithelial type. Stromal tumours are the next most frequent and are most commonly gastrointestinal stromal tumours, followed by leiomyoma and schwannoma. We present an exceptional case of a patient with a gastrointestinal stromal tumour with suspicion of residual gastric disease, which was diagnosed post-operatively as a schwannoma.

Postsurgical Paracicatricial Cutaneous Satellitosis of Giant Cell Tumour of the Tendon Sheath, Localized Type

2011

Tenosynovial giant cell tumour (localized type) is a tumour of tendon sheaths and interphalangeal joints, affecting the digits and arising from the synovium. It is characterized by a proliferation of mononuclear cells and osteoclast-like polykaryocytes. Its propagation to the skin is an exceptional event, which can take place either in localized form in the fingertips (localized type) or in the rare diffuse form called giant cell tumour of the tendon sheath (diffuse type). We report here a case of giant cell tumour with cutaneous satellites, which appeared close to and around the surgical scar following the excision of the primary lesion, in a 9-year-old boy. In the cutaneous satellites, a …
