A Rare Clinical Presentation of an Osteochondroma of Coronoid Process of Mandible

Osteochondroma (osteocartilaginous exostosis) is one of the most common benign tumors of bone but is rare in the craniofacial region. Only a few cases of osteochondroma of the coronoid process have been reported in the literature, since the time of its discovery (osteochondroma of a coronoid process) by Jacob in 1899. We present a case of osteochondroma of the left coronoid process in a 16-year-old female patient. Contrary to the literature, our patient had no limited mouth opening despite a close approximation of left hyperplastic coronoid process with zygomatic arch, making it a unique case among similar cases. Plain radiography can be used for this hyperplastic condition but due to its inherent distortion and being only two-dimensional (2D) it has a limited diagnostic advantage. Cone beam computed tomography (CBCT) was employed for necessary diagnostic information. We managed our patient with an intraoral coronoidectomy

Internal Derangement of TMJ

Internal derangement of temporomandibular joint can be defined asAnteriomedial displacement of disc, associated posteriosuperior displacement of condyle in the closed jaw position.Temporomandibular joint (TMJ) is a sensitive, complex and highly mobile joint. Temporomandibular disorders (TMD) are a class of degenerative musculoskeletal conditions associated with morphologic and functional deformities that affect up to 25% of the population. The most frequent structural (as opposed to muscular) cause of TMD are the Internal derangement , that involves progressive slipping a displacement of component of temporomandibular joint called articular disc. Because the deranged joint willcontinue to try to function in an impaired manner, so that internal derangement disorder often get progressively worse with time. In the mechanically demanding and biochemically active environment of the TMJ, therapeutic conservative and surgical approaches that can restore joint functionality while responding to changes in the joint have become a necessity

Solid-pseudopapillary neoplasm of the pancreas: A classical presentation with unique paranuclear dot like immunostaining with CD 99

A 32-year-old lady presented with a history of abdominal pain and upper abdominal discomfort of 3 months duration. Her imaging studies done at a local hospital showed a solid-cystic mass involving head of the pancreas. The patient was referred to our surgical oncology department. On examination, there was a nontender mass in the epigastrium. An ultrasound scan guided fine-needle aspiration (FNA) was done which was showing classical features of solid-pseudo papillary neoplasm of the pancreas. With this preoperative diagnosis patient was taken up for surgery. Per operatively, there was a solid-cystic mass in the head of the pancreas. Pancreaticoduodenectomy was done. Histopathology and immunohistochemistry (IHC) confirmed the diagnosis of solid-pseudo papillary neoplasm of the pancreas. Apart from the routine IHC panel, CD 99 immunostain was also done which demonstrated the characteristic paranuclear dot-like staining observed in previous studies in the literature
