A pathologically elongated coronoid process forming a joint with the zygomatic arch and bone is termed as "Jacob's disease." Herein, we present a case of Jacob's disease, which has rarely been reported in the literature. Moreover, very few cases have been reported from the Indian subcontinent. A 28 years-old male reported to us with progressive restriction of mouth opening. After detailed imaging, coronoidectomy was performed through an intraoral approach. A mushroom-shaped gross specimen was obtained. Osteochondroma of the coronoid process was diagnosed based on the histopathologic examination of the excised tissue. Although Jacob's disease is seldom considered in the list of differential diagnoses for restricted mouth opening, our case highlights the need for evaluation of the coronoid process, which is usually ignored during routine radiographic examination. The report also highlights the miniscule incidence of this condition in the available literature.
一种病理上伸长的冠状突与颧弓和骨形成关节的情况被称为“雅各布病”。在此，我们报告一例雅各布病病例，该病在文献中鲜有报道。此外，印度次大陆报道的此类病例也非常少。一名28岁男性前来就诊，主诉为张口逐渐受限。经过详细的影像学检查后，通过口内入路进行了冠状突切除术。获得了一个蘑菇状大体标本。根据切除组织的组织病理学检查诊断为冠状突骨软骨瘤。尽管在张口受限的鉴别诊断清单中很少考虑雅各布病，但我们的病例强调了对冠状突进行评估的必要性，而冠状突在常规影像学检查中通常被忽视。该报告还突出了这种情况在现有文献中的微小发病率。
