Pleomorphic adenoma of the external auditory canal: a case report and review of the literature.

Pleomorphic adenomas of the external auditory canal (EAC) are benign tumors of the ceruminal glands; they are a rare entity. Arising from the lateral cartilaginous portion of the EAC, these lesions can be challenging to diagnose in view of their rare clinical presentation, indolent symptoms, and a lack of familiarity on the part of histopathologists. We report the case of a pleomorphic adenoma in a 32-year-old woman, and we review the literature on glandular neoplasms of the EAC, with particular emphasis on terminology and factors that can hinder the diagnosis.

Tracheobronchial stenting in an infant with an anomalous right main bronchus.

Congenital anomalies of the right main bronchi have not been fully described. Bronchial anomalies are usually asymptomatic unless they coexist with other abnormalities. We describe a rare bronchial anomaly in a 2-month-old girl in which the right upper lobe, middle lobe, and lower lobe bronchi all originated at the same point as a result of a developmental teratogenic long right main bronchus and an absent bronchus intermedius.

Nevoid basal cell carcinoma syndrome and fetal rhabdomyoma: a case study.

Fetal rhabdomyoma is not generally considered part of nevoid basal cell carcinoma syndrome. However, a review of the literature revealed five patients with this syndrome who also had fetal rhabdomyomas in various locations. We report the first patient with nevoid basal cell carcinoma syndrome and a fetal rhabdomyoma of the tongue.

First report of a lipoblastoma of the parapharyngeal space.

Lipoblastoma is a rare benign tumor that occurs primarily in children younger than 3 years of age. Fewer than 100 cases have been reported in the literature, and only eight cases have been previously reported in the head and neck; two of them occurred in the parotid region, where the differential diagnosis becomes quite extensive. We report a new case of head and neck lipoblastoma--one that occurred in the parapharyngeal space, a site that has not been previously reported.
