ameloblastomas are regarded as a homogeneous group of neoplasms with locally invasive character. they generally do not show induction of dental hard tissue formation except in few cases. biological behavior and histogenesis of these tumors is still unexplored as there is lack of relevant studies and long follow-up of these patients. so, we aimed to report this rare case of dentinoameloblastoma ...

Calcifying odontogenic cyst (COC) is an odontogenic cyst with accumulation of ghost cells that has central and peripheral subsets. Here, we present an 11-year-old male patient with an intraoral swelling on the left posterior mandibular ridge interfering with eruption of the second molar. Histopathologic examination revealed a cystic lesion lined by ameloblast-like epithelium in the basal layer ...

BACKGROUND AND AIM Researchers have demonstrated dead cells in radiofrequency ablation (RFA) lesions that have morphological similarities to viable tumor cells and are thus referred to as ghost cells. However, studies on how long ghost cells persist have not been systematically performed. METHODS A tumor model was established by implanting VX2 tumor tissue into the livers of 48 New Zealand ra...

Ghost cell odontogenic carcinoma (GCOC) is an extremely rare that typically characterized by admixture of atypical epithelial cells and ghost cells. Up to date, GCOC remains with around 58 cases have been reported. Herein,we report a case the mandible, patient particularly young, successfully treated surgical resection, reconstruction, radiation, followed for 2 years without any sign recurrence...

introdouction: the mapping of ghost images of the maxilla and the nasal cavity, which are complex structures, is very important. the position of objects that create a ghost image can differ when using various devices. the purpose of this investigation was to study the mapping of ghost images of the maxilla and the nasal cavity using a cranex d digital panoramic machine. materials and methods: t...

Many research workers have made an attempt to elucidate the nature of ghost cells by employing special histochemical methods, transmission electron microscopy, and scanning electron microscopy, and several hypotheses have been offered without any universal agreement. With the purpose of unraveling some of the facts regarding ghost cells with emphasis on their histogenesis, a comprehensive revie...

BMJ Case Reports Published online: [please include Day Month Year] doi:10.1136/ bcr-2012-008477 DESCRIPTION A 65-year-old Japanese man with advanced lung cancer was admitted with a 2-week history of cough and general fatigue. On physical examination, the patient appeared to be chronically ill; his blood pressure was 115/52 mmHg, pulse rate was 97 beats/min and regular, temper...

Chloroviruses infect their hosts by specifically binding to and degrading the cell wall of their algal hosts at the site of attachment, using an intrinsic digesting enzyme(s). Chlorovirus PBCV-1 stored as a lysate survived longer than virus alone, suggesting virus attachment to cellular debris may be reversible. Ghost cells (algal cells extracted with methanol) were used as a model to study rev...
