Fulltext Pleomorphic adenoma of the trachea

Ashwaq AM, Sani A

Med J Malaysia, 2007 Jun;62(2):162-3.

Primary tracheal tumors are very rare. Pleomorphic adenoma is rarely found in the trachea, despite being the most common histological form of salivary gland neoplasm. We present a case of pleomorphic adenoma of the trachea. Bronchoscopic excision using cold instruments resulted in apparently normal tracheal mucosa.

Benign chondroid syringoma of the orbit: an atypical location

Yap JF, Madatang A, Hanafi H

Orbit, 2020 Apr;39(2):135-138.

PMID: 31023118 DOI: 10.1080/01676830.2019.1604766

A 31-year-old male with no known medical illness presented with painless left eye protrusion for the past 2 years. Radiographic features were of an extraconal superior orbital mass with no invasion of adjacent structures. The patient underwent an excisional biopsy of the left superior extraconal mass a week later. The histopathological examination revealed a well-circumscribed lobulated mass with chondroid and myxoid stroma enveloping benign bland-appearing epithelial and myoepithelial cells. These pathological features were consistent with benign chondroid syringoma of the orbit. The patient had an uneventful recovery with no active ocular complaint post-operatively.Despite chondroid syringoma of the orbit being a rare tumour, it should be considered in the differential diagnosis of periorbital masses. Excision of the tumour remains the treatment of choice with histopathological examination as the gold standard of diagnosis. Regular follow-up is warranted in view of possible local recurrence or metastasis.

We reported a case of pleomorphic adenoma of the lacrimal gland involving the palpebral lobe in young teenage girl of Asian origin. The presentation at young age group is rare, which initially misdiagnosed as a large chalazion. The benign tumor with its intact pseudocapsule was removed through lateral orbitotomy together with the suspicious looking orbital lobe.

Benign parotid lesions: is near total parotidectomy justified?

Arshad AR

PMID: 17219001

INTRODUCTION: Benign tumours of the parotid gland constitute about 80% of parotid tumours. The most common benign tumour of the parotid gland is pleomorphic adenoma. Other conditions, like Kimura's disease, may mimic a tumour when they present as a parotid mass. Various modes of treatment have been advocated for the treatment of benign parotid lesions, ranging from enucleation to near-total parotidectomy.

MATERIAL AND METHODS: This is an audit of an 18-year period where 173 lesions of the parotid gland (34 malignant and 139 benign lesions) were treated by the author.

RESULTS: There were 139 benign lesions, of which 123 were benign tumours and 16 non-tumour conditions. Fourteen cases of recurrent pleomorphic adenoma of parotid that had been treated elsewhere were also operated on. Near-total parotidectomy was performed on all these cases with benign lesions.

CONCLUSIONS: There has been no recurrence in all the patients who was treated this way. Near-total parotidectomy should be considered when there is a need to treat benign parotid swellings.

Fulltext Carcinoma ex pleomorphic adenoma: a case report and review of literature

Khanna D, Chaubal T, Bapat R, Abdulla AM, Philip ST, Arora S

Afr Health Sci, 2019 Dec;19(4):3253-3263.

PMID: 32127904 DOI: 10.4314/ahs.v19i4.50

Background: Carcinoma ex pleomorphic adenoma (CA-ex-PA) is extremely unusual in minor salivary glands of oral cavity. CAex-PA is a carcinomatous change as a primary or as a recurrence of pleomorphic adenoma.

Objective: Due to resemblance of clinical symptoms of Ca ex PA and benign pleomorphic adenoma, it is mandatory for surgeons to keep high degree of clinical alertness, considering the peculiarity of this tumor.

Case Report: 54-year-old male presented with swelling on left side in the pre-auricular region from the middle of zygomatic arch to mastoid process and from tragus of the ear up to angle of mandible. Fine needle aspiration cytology revealed a mixture of benign and malignant components. Total left parotidectomy with left radical neck dissection followed by reconstruction with cervicodeltopectoral flap was performed. Combination of chemotherapy and radiotherapy were given to patient. Histologic examination and pre-operative fine needle aspiration cytology confirmed the diagnosis of Carcinoma ex pleomorphic adenoma (CA-ex-PA). Two-year follow-up of patient showed no recurrence of the lesion.

Conclusion: Due to the similarity in the clinical symptoms of CA-ex-PA and benign pleomorphic adenoma, it is vital that clinicians maintain a high degree of clinical vigilance, considering the oddity of this malignancy.
