HighlightsChoanal atresia is a congenital malformation of the nasal cavity characterized by the complete obliteration of the posterior choanae.Adult bilateral choanal atresia is a rare entity.Endoscopic transnasal choanoplasty is the criterion standard treatment.The exact role of the postoperative stent and use of mitomycin C is controversial.

Nodular hidradenoma is a rare benign adnexal tumor. It is most frequently encountered in the head and neck region, trunk, and extremities. This tumor exhibits a high recurrence rate, and an association with malignancy.Many names have been used to describe this pathology.We report the case of a nodular hidradenoma in a 30-year-old moroccan woman who presented with a 2-year history of a swelling in her right preauricular region. Histological examination revealed the typical appearance of a nodular hidradenoma. The tumor was excised and one year after the initial presentation, there was no sign of recurrence. We emphasize the importance of wide surgical excision with appropriate margins to prevent local recurrence. A close follow up of the patients is recommended.

IntroductionCarcinosarcoma is a highly malignant tumor characterized by dual malignant histologic differentiation of epithelial and mesenchymal components. The tumor is extremely rare in the sinonasal tract, with only 13 cases reported since 1957 in the literature.Presentation of caseWe report a case of a 55-year-old man with right-sided face pain revealed a mass in the right maxillary sinus and nasal cavity. A large incisional biopsy from the nasal cavity concluded the diagnosis of carcinosarcoma. The patient was treated with chemoradiation, but no significant effect was obtained. The patient died 4 months after initial examination.DiscussionIn our case, the patient consulted late with a large tumor which darkens his prognosis. According to some authors, this histological type of tumors is known by local recurrences and its lethal metastases. Prognosis is related to location, tumor size, the invasion and stage of disease. Wide surgical excision is the treatment of choice. Radiotherapy can be discussed in inoperable cases.ConclusionThis is an aggressive tumor, rapidly progressive with a poor prognosis. The management of this rare condition remains undetermined.

Introduction The fungal balls of the paranasal sinuses are usually seen in the maxillary and sphenoid sinuses. Although, the lesion of the concha bullosa, without sinus participation, is very uncommon. We report the case of a fungal ball of concha bullosa in an 88-year-old patient. Objective The objective of our review of literature is to investigate the epidemiological, clinical, paraclinical, and therapeutic characteristics of patients diagnosed with fungus ball in concha bullosa. Methods A case of a patient who was diagnosed with concha bullosa of a fungus ball is reported. Demographic data, clinical presentation, imaging, and treatments were recorded. Key images were obtained. A review of the literature was also performed. Results A total of 12 cases have been reported so far in the literature revealed by different symptoms. The mean age was 38.8 years and the gender ratio was ∼12 (female):1 (male). The endoscopic surgical approach was the most frequently used treatment and provides good outcomes. Neither postoperative complications nor recurrences were noted, however, there is insufficient follow-up data. Conclusion Concha bullosa fungal ball is a rare diagnosis that can be revealed by different symptoms. It should be considered in patients with and unexplained chronic facial pain. A preoperative computed tomography scan is an essential tool in making a diagnosis. Endoscopic surgery is the treatment of choice, with a low morbidity and recurrence rate.

HighlightsMandibular metastasis of thyroid cancer are rare and the initial metastases revealing papillary carcinoma are exceptional.Few cases are reported in the literature.Due to their rarities and relative lack of data on their management, there is no clearly defined processing algorithm.
