Carcinoma ex pleomorphic adenoma: a case report and review of literature
Background: Carcinoma ex pleomorphic adenoma (CA-ex-PA) is extremely
unusual in minor salivary glands of oral cavity. CA-ex-PA is a
carcinomatous change as a primary or as a recurrence of pleomorphic
adenoma. Objective: Due to resemblance of clinical symptoms of Ca ex PA
and benign pleomorphic adenoma, it is mandatory for surgeons to keep
high degree of clinical alertness, considering the peculiarity of this
tumor. Case Report: 54-year-old male presented with swelling on left
side in the pre-auricular region from the middle of zygomatic arch to
mastoid process and from tragus of the ear up to angle of mandible.
Fine needle aspiration cytology revealed a mixture of benign and
malignant components. Total left parotidectomy with left radical neck
dissection followed by reconstruction with cervicodeltopectoral flap
was performed. Combination of chemotherapy and radiotherapy were given
to patient. Histologic examination and pre-operative fine needle
aspiration cytology confirmed the diagnosis of Carcinoma ex pleomorphic
adenoma (CA-ex-PA). Two-year follow-up of patient showed no recurrence
of the lesion. Conclusion: Due to the similarity in the clinical
symptoms of CA-ex-PA and benign pleomorphic adenoma, it is vital that
clinicians maintain a high degree of clinical vigilance, considering
the oddity of this malignancy
Ameloblastic Fibroodontoma: Uncommon Case Presentation in a 6-Year-Old Child with Review of the Literature
Ameloblastic fibroodontoma is a benign mixed odontogenic neoplasm considered in patients with asymptomatic swelling and unerupted teeth that exhibit histologic features between ameloblastic fibroma and complex odontoma. Radiographically, this lesion appears as radiolucency admixed with focal radio opaque masses of irregular shapes and sizes. This lesion is confirmed by the presence of proliferating odontogenic epithelium, ectomesenchyme, and dental hard tissue formation on pathological analysis supplementing clinical and radiographic findings. As this tumour is less commonly seen in routine clinical practice, ameloblastic fibroodontoma with detailed orofacial features and periodic approach to its diagnosis is discussed. This paper reports a case of ameloblastic fibroodontoma of the mandible in a 6-year-old male patient with an uncommon case presentation and review of the literature
Endodontic Management of a Severely Dilacerated Mandibular Third Molar: Case Report and Clinical Considerations
This article aims at providing an insight to the clinical modifications required for the endodontic management of severely dilacerated mandibular third molar. A 35-year-old patient was referred for the root canal treatment of the mandibular left third molar. An intraoral periapical radiograph revealed a severe curvature in both the canals. A wide trapezoidal access was prepared following the use of intermediate-sized files for apical preparation. Owing to increased flexibility, Hero Shaper NITI files were used for the biomechanical preparation and single cone obturation was carried out. Third molars owing to their most posterior location-limited access coupled with a severe curvature pose utmost clinical challenges require meticulous skill, advanced technology, and patience to achieve success
