Histopathological patterns and biological characteristics of ameloblastoma: A retrospective cross-sectional study.

Objectives: This study aims to determine the histopathological patterns and biological characteristics of ameloblastoma.

Methods: This was a cross-sectional retrospective laboratory-based study using 82 formalin-fixed paraffin-embedded tissue blocks from patients diagnosed histologically with ameloblastoma. Information regarding age, sex, anatomical location of the lesion, histopathologic type, and biological behaviour or characteristics of the types of ameloblastoma was obtained from laboratory request forms.

Dumbbell-Shaped Extramedullary Hemangioblastoma of the Thoracic Spine as a Diagnostic Dilemma of Solitary Fibrous Tumor.

Introduction: Extramedullary hemangioblastoma is a very rare entity that has been rarely reported in the literature.

Case Presentation: A 17-year-old female presented with limping that rapidly progressed to paraparesis and urine incontinence over a one-month duration. Clinically, she had a small swelling on her spine.

Intracranial neuromuscularchoristoma: a case report and literature review.

Neuromuscular choristoma (NMC) is an uncommon tumor that usually involves a large nerve trunk. Only 28 cases of NMC have been previously reported in the English-language literature, 17 of which involved cranial nerves. We report a new case of intracranial NMC that arose from a facial nerve at the cerebellopontine angle in a 44-year-old man.

Histologic distribution of fatal rotaviral pneumonitis: an immunohistochemical and RT in situ PCR analysis.

Rotaviral infection is a common cause of gastroenteritis and pharyngitis; to our knowledge, infection has not been associated with severe pneumonia. We report on two cases of fatal pneumonitis in 49-and 54-year-old men; the latter was on long-term steroid treatment of multiple sclerosis. In the latter case, the histologic examination after a several week history of symptoms showed severe organizing interstitital pneumonitis and necrotizing bronchiolitis with extensive squamous metaplasia.
