The high rate of mortality associated with cancer is due to its inherent nature to metastasize. Perineural invasion (PNI) is a relatively rare mode of metastasis, and a distinct pathologic entity that can be observed in the absence of lymphatic or vascular invasion which is still shrouded by mystery. PNI is a marker of poor prognosis. Despite increasing recognition of this metastatic process, there has been little progress in the understanding of mechanisms behind PNI. The purpose of this article is to make surgeons aware of caudad to cephalad metastasis of oral cancer along trigeminal nerve.
Sarcomatoid carcinoma (SC) is a rare and unique disease of the oral cavity. It is a biphasic squamous cell carcinoma with sarcoma-like characteristics. It is a strikingly aggressive lesion with a rapid rate of growth and a high rate of metastasis. Diagnosing a sarcomatoid carcinoma may present a challenge; most can only be ascertained by immunohistochemical study. An aggressive treatment plan should be devised for this uncompromising disease with a readiness to accept the dire outcome. We hereby present a case of a 50-year-old male patient, with no history of deleterious habit, diagnosed with SC of the buccal mucosa that proved to be fatal.
Presence of teeth at birth or before its normal eruption time frame is an occurrence of rarity. Natal and neonatal teeth are observed in infants at birth or within thirty days of life. The etiology of natal and neonatal teeth is still not clearly understood. A thorough clinical knowledge and proper treatment plan is essential to manage such rare conditions which are often entangled with varied social taboos. Here we report a case series of natal and neonatal teeth in the lower anterior region with clinical, histological aspect and its management. .
Intermaxillary fixation (IMF) plays an important role in the treatment of maxillofacial fracture. The most preferred way is upper and lower arch bar fixation or eyelet wiring and imf done by box wiring. Here we present a new type of imf technique, using 26 gauze stainless cut into 6cm length singe wire technique. It is a single, quick, economical, minimal invasive and easy technique without any arch bar or eyelet fixation. Indication for this kind of wiring is undisplaced or minimally displaced fractures, stabilization of fractures during open reduction and internal fixation, orthognathic surgery and in tumor resection surgeries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
