• Abstract

  Mesenchymal lesions with spindle cell proliferation comprise a diverse group of reactive and neoplastic processes. The pathologist is commonly exposed to this group of diseases and the high microscopic similarity observed between these entities makes the diagnosis a challenge, compromising the treatment of patients. Myofibromas may be associated with myofibromatosis and commonly affect th…

• Abstract

  Follicular lymphoid hyperplasias (FLH) are seldom diagnosed in the oral cavity; however, only few case reports are available in literature, avoiding a better understanding of this entity that is difficult to be distinguished from extranodal non-Hodgkin lymphomas. Approximately, 3 to 5% of all lymphomas are identified in the oral cavity, and the diffuse large B cell lymphoma not otherwise …

• Abstract

  Odontogenic tumors are a highly heterogeneous group of lesions derived from dental tissues, occurring in the jaw and adjacent tissues. Due to their clinicopathologic variability, the diagnosis of these tumors becomes a real challenge even for experient pathologists, which contributes for the discrete knowledgment concerning biologic factors involved in the clinical behavior of these lesio…
