Abstract

Pleomorphic adenoma is rare in pediatric populations, where viral and congenital problems are the usual culprits responsible for submandibular masses. We report the case of a 12-year-old child who presented with a painless right submandibular mass that had developed over the course of 4 months. The patient denied fever, erythema, and edema. The mass was diagnosed as a branchial cleft cyst before complete excision was performed. The pattern and etiology of a pleomorphic adenoma in children differs from those in adults. In children, it requires prompt and correct diagnosis to keep morbidity and mortality at a minimum.

Massive calcification in a pleomorphic adenoma: Report of an unusual presentation

Abstract

We report a case of histology-proven pleomorphic adenoma of the parapharyngeal space in a 20-year-old man. This case was unusual in that a massive amount of dystrophic calcification was scattered throughout the tumor. The patient underwent successful surgical resection, and he exhibited no signs of recurrence during follow-up. Literature about such an unusual presentation is scarce.

Abstract

Middle ear adenoma is a rare disease that arises from the mucosa of the middle ear. Only a few cases of associated facial nerve paralysis have been reported. Facial nerve involvement is most likely related to nerve compression rather than tumor invasion of the nerve. We describe a case of a huge middle ear adenoma in a 63-year-old man. He presented with a 1-month history of right-sided otalgia, otorrhea, and facial palsy; he also had a 10-year history of right-sided hearing loss. A tympanomastoidectomy was performed. Intraoperatively, the tumor was found to fill the middle ear cavity as well as the entire diameter of the external auditory canal. The tumor had eroded the wall of the facial canal at the second genu, and it was tightly adherent to the epineurium. Focal inflammation around the tumor was observed at the exposed facial nerve. The tumor was removed and the facial nerve was decompressed. Immediately after surgery, the patient’s aural symptoms resolved. The final pathology evaluation established the diagnosis of a middle ear adenoma. At the 3-year follow-up, the ear cavity was completely healed and facial nerve function was improved.

Approach to benign tumors of the palate: Analysis of 28 cases

Abstract

We conducted a retrospective analysis of 28 patients-15 men and 13 women, aged 17 to 71 years (mean: 41.6)-who had undergone surgery for the treatment of a benign tumor of the hard or soft palate. The most common chief complaint was a palatal mass, which was reported by 14 patients (50.0%). Tumors were more common in the hard palate than in the soft palate by a margin of 23 to 5 (82.1 to 17.9%; p = 0.001). The most common histopathologic diagnosis was pleomorphic adenoma, which occurred in 9 cases (32.1%). Most patients were treated with local excision with clear margins, which was sufficient in almost all cases, as there were only 2 recurrences, both of which occurred in men with a hard-palate pleomorphic adenoma. For these 2 patients, a wider excision and repair with palatal islet flaps was performed, and no further recurrence or malignant transformation was observed during follow-up. Two patients with a soft-palate hemangioma were treated with an intralesional steroid injection and radiofrequency ablation, which reduced the size of their lesion considerably.

Pleomorphic adenoma of the nasal cavity: A case report

article

Abstract

Pleomorphic adenomas of the nasal cavity are rare. We describe the case of a middle-aged white man who presented to our clinic with a long history of unilateral nasal obstruction. Preoperative imaging was performed, and the patient was taken to the operating room for endoscopic excision of the lesion. Surgical margins were negative. The patient's nasal obstruction resolved, and he was doing well at his first postoperative visit. The pathologic diagnosis was a pleomorphic adenoma. We discuss the features and management of this entity.

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

article

Abstract

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.

Cavernous sinus syndrome secondary to pituitary adenoma: A case report

article

Abstract

In this case report we demonstrate the intimate association between the sella turcica and the cavernous sinus and review the neuroanatomy involved. The otolaryngologist should be aware of this association when collaborating with a neurosurgeon in pituitary surgery.

Neuroendocrine adenoma of the middle ear (NAME)

article

Abstract

Neuroendocrine adenoma of the middle ear (NAME) is a rare tumor. We report a case of NAME, the clinical and pathologic findings of which illustrate the biologic behavior of adenomatous tumors of the middle ear and their relationship with rare carcinoid tumors of the middle ear. A 29-year-old man presented with a history of recurrent otitis media, right conductive hearing loss, and aural fullness. The tumor was removed in its entirety. Otolaryngologists should be familiar with this unusual but important entity.
