A 75-year-old woman presented with chronic persistent left nasal obstruction and gradual painless non-axial proptosis with loss of vision in the left eye. Computed tomography scan showed an iso-dense lesion filling the frontal, left ethmoidal and sphenoidal sinuses, and the nasal cavity, with extension into the left orbit. She underwent surgical tumor resection with orbital exenteration and histology revealed features of an aggressive hyperkeratotic squamous papilloma arising from the sino-nasal region. Although squamous papillomas have been natively associated with the oral cavity and oropharynx, they present less frequently as sino-nasal tumors with orbital invasion.展开更多

The cervicofacial localization is the most common. The aim of this report case was to show a rare case of nasal localization, to the 48-year old patient, treated in poor medical condition. <strong>Case presentation:</strong> The patient consults late with enormous nasal mass involving for five years. After biopsy and facial CT-scan, a surgical procedure was performed. The evolution was good and the final pathology confirms the diagnosis. The objective of this case report was to show the originality of the presentation and the difficulties for management in poor medical environment. <strong>Conclusion:</strong> Abrikossof’s tumor is a rare benign tumor but whose preferential development occurs at the expense of the ENT sphere. Large forms remain the preserve of poor environments. The diagnosis is pathological and the treatment is surgical.展开更多

The present study describes the occurrence of the primary oral and nasal TVT in a 10-year-old, female, mix-breed dog. The case was presented with a history of anorexia, inability to swallow and dyspnea. Clinical examinations revealed the emaciation, muzzle deformity due to the presence of a friable, fleshy, cauliflower-like mass in the oral cavity and submandibular lymphadenopathy. TVT was diagnosed based on histopathological findings. The dog was discharged with therapeutic intervention with vincristine. Unfortunately, the case died before readmission because of the progressive worsening of the general condition. Our findings highlight the need for considering TVT for the differential diagnosis of the extragenital masses in dogs.展开更多

They are of unknown exact etiology, but it is suggested that it is due to abnormal tissue migration during early embryonic development. Nasal dermoid cysts albeit rare, can present in various forms such as sinuses, fistulas, or intracranially extending tracts. They can be asymptomatic and incidentally discovered or present with a visible external mass or sinus that is either painful, infected or cosmetically concerning. If nasal dermoid cysts with an intra-nasal bone sinus tract are left untreated, they can lead to life-threatening complications. This report describes the case of a 6-year-old girl with a nasal dermoid cyst connected to a superficial punctum by an intra-nasal tract. She had undergone surgical excision of a nasal swelling previously diagnosed as a dermoid cyst. One year later, she returned to our clinic with a recurrence of the nasal swelling. Imaging tests revealed a nasal dermoid cyst with a tract extending to the nasal tip, without intracranial expansion. The cyst, along with the entire tract, was successfully removed surgically, and the postoperative follow-up indicated no complications. Histopathology confirmed the diagnosis of a dermoid cyst. This case underscores the significance of considering the dermoid tract in nasal cyst cases and the necessity of its complete removal to prevent recurrence.展开更多

Conventional removable prostheses have usually been indicated and performed for prosthodontics. When the patient has an edentulous maxilla, the unfavorable stability of the prosthesis will cause dysfunction of mastication and pronunciation. To achieve improvement of the impaired functional situation, implant-supported full fixed prostheses (IPSPs) for the edentulous maxilla with a removable obturator offer a reasonable solution. We present herein the case of a 70-year-old Japanese man who has presented with oro-nasal defect due to surgical procedures for oral cancer. He was treated with implant-supported full fixed prostheses in a conventional two-step procedure. After prosthesis treatment, a palatal obturator was set. The patient has shown no clinical or radiological evidence of failure as of 24 months after the end of treatment. Functional evaluation of mastication and pronunciation showed dramatic improvements. For a patient with an edentulous maxilla and palatal fistula, full-arch fixed prostheses supported by a combination of axially and non-axially positioned implants and a removable oro-nasal obturator, using the anterior alveolar bone, without bone transplantation or maxillary sinus elevation, could offer an effective, minimally invasive treatment alternative.展开更多
