The aim of this study was modelling the spatial distribution ofLilium ledebourii (Baker) Boiss. based on ecological characteristics, in order to predict potential habitats for conservation of a rare plant. Knowledge of the spatial distributions of rare and threatened species and the underlying ecological factors plays an important role in regional conservation assessments and development planni...

schwannoma(neurilemmoma) is a benign tumor originates from schwann cells. ancient (degenerated) schwannoma is a long-standing schwannoma with degenerative changes. head and neck region is one of the most common sites for nerve sheath tumors but intraosseous schwannoma is rare. the mandible is the most common site of occurrence for this lesion. we report a rare case of intraosseous ancient schwa...

cytomegalovirus is the most common viral infection after kidney transplantation. clinical presentations of cytomegalovirus infection range from asymptomatic infection to organ-specific involvement. most symptomatic infections manifest as fever and cytopenia. the gastrointestinal tract is the most common site of tissue-invasive infection, often presenting as diarrhea or gastrointestinal bleeding...

  Extra-skeletal Ewing’s sarcoma is a rare soft tissue malignant neoplasm, morphologically indistinguishable from skeletal Ewing’s sarcoma. The usual sites of involvement are the soft tissues of para-vertebral region, chest wall, and lower extremity. Extra-skeletal Ewing’s sarcoma is rare in the head and neck region and very few cases are reported in the parotid gland. The cytological features...

Leiomyoma of nasal cavity is a rare and benign tumor of smooth muscle origin that uncommonly arises from the nasal septum. We present an unusual case of histopathologically diagnosed locally extensive leiomyoma of the nasal septum which was clinically and radiologically misdiagnosed as malignancy of the nasal cavity. This case report emphasizes the rare occurrence of this entity at this site an...

Hypohidrotic ectodermal dysplasia (HED) is a rare congenital disorder arising from deficient development of ectoderm-derived structures including skin, nails, glands and teeth. The phenotype of HED is associated with mutation in EDA, EDAR, EDARADD and NEMO genes, all of them disruptingNF-κB signaling cascade necessary for initiation, formation and differentiation in the embryo and adult. ...
