A 6-year-old male cross-breed rabbit ( Oryctolagus cuniculus) was presented with lameness and severe swelling from the right shoulder to brachium. On 16-detector helical computed tomography images of the amputated right forelimb after being fixed in formalin, evident proliferative and destructive lesions of bone were observed. On histologic examination, the tumor was composed of proliferating neoplastic cells that resembled histiocytes, with abundant osteoid production. A large number of multinucleated giant cells were found throughout. This case was diagnosed as osteosarcoma by clinical, radiographic, and histologic findings. This is a rare case report of osteosarcoma in a rabbit consistent with canine predilection sites.

Patient’S History

Bilateral Tessier no. 7 clefts are rarely reported in the literature. Here, we describe the presence of accessory maxilla with supernumerary teeth in a patient who exhibited bilateral Tessier no. 7 clefts; the diagnosis was established based on the patient’s history, clinical presentation, and computed tomography images. A review of the available literature revealed 24 patients with Tessier no. 7 clefts from 2000 to 2020, including our patient. The most common clinical manifestation in patients with Tessier no. 7 clefts comprises bilateral facial clefts. Additionally, Tessier no. 7 clefts are more frequently found in boys or men, rather than in girls or women. The presence of an accessory maxilla with supernumerary teeth in a patient with bilateral Tessier no. 7 clefts is extremely rare. Early detection of craniofacial abnormalities is important, because it may influence patient prognosis and management.

Abstract Osteomas are slow growing bone tumours and are often asymptomatic. Rarely, they can be present in the temporal bone—only few cases had been reported, with an incidence of 0.1–1%. We describe a case of an osteoma of the temporal bone (retromastoid) found in a 40 year old female, who presented with a slow growing swelling behind the right ear for 9 years. Diagnosis was made on non-contrast computed topography (CT) of the skull. Treatment is indicated in symptomatic cases or cosmetic reasons. Screening colonoscopy and genetic testing for familial adenomatous polyposis (FAP) and Gardner’s syndrome are advised.

Abstract Ameloblastic fibrosarcoma (AFS) is a rare, aggressive malignant odontogenic tumor. AFS is seen most frequently in second and third decades of life. We are reporting a case of a low grade AFS in a 21-year-old male complaining of a painless swelling in the right side of the maxilla. The patient was treated with surgical excision followed by radiotherapy, which is considered the most effective approach for most of soft tissue sarcomas. AFS has a high-reported recurrence rate (up to 37%); therefore, long-term surveillance for recurrence is crucial.

<p>Epidermoid carcinoma is a frequent tumor in the upper aerodiodestive tracts, and depending on its location and tumor, nodes, metastases (TNM) stage, its therapy and prognosis vary enormously. Its location in the hypopharynx is rare, and in children or young adolescents, this location is extremely rare; The incriminated causes and the pathophysiology of the development of these tumors at this age remain a mystery. We present the case of a young patient of 13 years old, followed for squamous cell carcinoma of the right piriform sinus, with contralateral synchronous tonsil localization, and right lateral cervical lymphadenopathy fixed at 5 cm. In the absence of existing guidelines on the management of this type of location at this age, a multi-disciplinary meeting was necessary to decide on the management of this difficult case at this age.</p>

ABSTRACT Aim To report on a patient with Eagle's syndrome with a complete and very large ossification of the stylohyoid complex on the right side that to our best knowledge has never been published previously. Background Eagle's syndrome is characterized by a set of symptoms that are caused by the irritation of the neurovascular and soft-tissues caused by an elongated styloid process or ossification of stylohyoid ligament. Case description Because of the high discomfort and pain degree as well as limitations of mandibular and head mobility and also the thickness of the ossified stylohyoid chain, the patient was treated surgically by removing the hypertrophic segment. Conclusion These symptoms subsided completely after the surgical excision of the anomaly. The elongated styloid process on the left side was symptom free. Clinical significance Eagle's syndrome symptoms are not specific and can mimic those of other disorders, the syndrome must be included in the differential diagnosis of patients with pain in the orofacial, pharyngeal and cervical area.

Abstract Background: Fewer than 200 benign multicystic peritoneal mesothelioma cases were reported worldwide till 2017, while its pleural involvement has rarely been reported. Case presentation: We report a 70-year-old man who presented with three months history of chronic cough. Surgical resection was performed, and the pathology confirmed benign multicystic pleural mesothelioma. The patient underwent right lateral thoracotomy, wedges resection of the right upper lobe, and parietal pleurectomy and was discharged with an uneventful postop course.Conclusion: Based on published literature to date, this is the second reported case of pleural involvement of this disease.

Amyand's hernia is a rare form of an inguinal hernia (less than 1% of inguinal hernias) which occurs when the appendix is a part of hernial sac. Because of anatomical position of the appendix, it is most commonly found in the right sided hernial sac and it can also be accompanied by the caecum and/or right colon. In rare case, Amyand’s hernia can appear on the left side also. Here we report a case of left sided amyand’s hernia with acute perforated appendicitis in a 58 years old male patient at GMERS hospital, Dharpur, Patan, Gujarat, India.
