Histological features and ki-67 index in cervical atypical lesions
2008
One of the most frequent challenges in routine diagnostic assessment of cervical biopsies consists of some lesions in which histological features of HPV infection are either inconsistently present or only mildly/focally evident. We named them Atypical Lesions (AL) because differential diagnosis with metaplastic/reactive lesions and LSIL is difficult. It would be important to identify among them those lesions that are really HPV-associated. We studied 52 AL cases to evaluate whether the morphological features and the proliferation index, assessed by Mib1 (Ki67) immunostaining, would be useful to better understand the real nature of AL, with relation to the HPV presence and to the proliferati…
Fatal cerebellar haemorrhage due to phenprocoumon poisoning.
1996
A 32-year-old patient died of a cerebellar haemorrhage and the blood coagulation analysis before death suggested defective synthesis of vitamin K-dependent clotting factors due to vitamin K deficiency. The post-mortem toxicological examination of different tissues revealed phenprocoumon poisoning as the cause of death. The differential diagnosis of vitamin K deficiency and the toxicology of hydroxycoumarins are discussed.
Clinical and MRI measures to identify non-acute MOG-antibody disease in adults
2022
Abstract MRI and clinical features of myelin oligodendrocyte glycoprotein (MOG)-antibody disease may overlap with those of other inflammatory demyelinating conditions posing diagnostic challenges, especially in non-acute phases and when serologic testing for MOG antibodies is unavailable or shows uncertain results. We aimed to identify MRI and clinical markers that differentiate non-acute MOG-antibody disease from aquaporin 4 (AQP4)-antibody neuromyelitis optica spectrum disorder and relapsing remitting multiple sclerosis, guiding in the identification of patients with MOG-antibody disease in clinical practice. In this cross-sectional retrospective study, data from 16 MAGNIMS centres were i…
A perioperative uncontrollable bleeding in an elderly patient with acquired hemophilia A: a case report
2013
Key Clinical Message Acquired hemophilia A should be taken into account in the differential diagnosis of perioperative bleeding in patients without any apparent reason for activated partial thromboplastin time prolongation.
Lipome du lobe profond de la glande parotide : à propos d'un cas rarissime
2006
The incidence of lipoma in the parotid gland is very low, and lipomas in the deep lobe of the parotid are extremely rare and seldom considered in the differential diagnosis of deep lobe parotid gland tumours. A deep lobe parotid gland lipoma is presented and discussed.
Diagnóstico diferencial inmunomorfológico de las lesiones quísticas maxilares con queratinización
2011
ResumenObjetivosLos quistes maxilares con queratinización son formas lesionales de carácter controvertido y de relevancia clínica, dada la implicación clínico-evolutiva del llamado tumor odontogénico queratoquístico (TOQ). En el presente estudio nos planteamos valorar la utilidad de las técnicas inmunohistoquímicas en la identificación de estas lesiones.Material y métodosSe analizan de forma retrospectiva las lesiones quísticas maxilares dotadas de fenómenos de queratinización interna, diagnosticadas en un mismo centro hospitalario, a lo largo de un periodo de 4 años, realizando un estudio inmunohistoquímico mediante la aplicación de un panel de cinco anticuerpos (Ki67, Bcl-2, p53, CK19, D2…
Aneurysma des Ductus arteriosus Botalli
2000
A congenital aneurysm of the ductus arteriosus Botalli was detected by chest X-ray as an intrathoracic mass in a 7-day-old infant. Following confirmation of the diagnosis by echocardiography and MRI the aneurysm was successfully resected via left lateral thoracotomy without cardiopulmonary bypass. The postoperative course was uneventful. Six years after operation the patient is asymptomatic and growing normally. An intrathoracic mass may be considered in the differential diagnosis especially in infants and children. Aneurysms of ductus arteriosus potentially are associated with serious complications. Timely diagnosis and early surgical intervention are decisive for prevention of serious com…
Tumor de células de la granulosa extraovárico con mutación FOXL2. Diagnóstico diferencial morfológico e inmunohistoquímico
2020
Extraovarian granulosa cell tumor is a very uncommon tumor and the identification of a recurrent mutation in FOXL2 may be used as another diagnostic tool along with the classical morphological and immunohistochemical findings. Here, we report a new case of extraovarian granulosa cell tumor in a 57 years old female patient presented with a sub-hepatic mass and abdominal pain. Histopathological examination of the excised mass showed features of adult-type granulosa cell tumor with α-inhibin, calretinin, WT1, S100, CD99 and progesterone receptor immunoreactivity. A FOXL2 mutation was detected on molecular biology study. A final diagnosis was an extraovarian adult-type granulosa cell tumor. We …
Fitz-hugh-curtis syndrome secondary to postpartum endometritis: Case Report and literature review
2021
We report a case of Fitz‑Hugh‑Curtis syndrome (FHCS) 1 week after an urgent cesarean section. Although its onset in the postpartum period is poorly reported in the literature, we suggest that FHCS can complicate puerperal endometritis; therefore, it should be consider in differential diagnosis in puerpera with right upper quadrant pain. Again, it can be useful to perform a contrast computed tomography that allows early diagnosis and conservative treatment
INTRACRANICAL HEMANGIOPERICYTOMA: CASE REPORT AND REVIEW OF LITERATURE
2013
PURPOSE: We present a case of intracranical hemangiopericytoma (HPC) in a patient with migraine (male, 49 years old), who also presented mental confusion and partial left sensorimotor syndrome. We will also provide some elements regarding the international classification of this rare and highly vascularized mesenchymal tumor, and will consider possible differential diagnosis with other more common extra-axial masses. METHODS: After a preliminary examination in ER, patient underwent to head CT examination and was then transferred to the neurosurgical unit. The day after a brain MR examination was performed using advanced techniques too (PWI, and MRS); before surgery also functional MR imagin…
