“…[ 4 ] Various theories have been put forward to explain the basis of HGST, for example, epithelial remnants from the brachial apparatus. [ 8 ] Pleomorphic adenoma is the second most common tumour of HGST, the first being Warthin’s tumour. [ 7 ] Very few cases of pleomorphic adenoma at ectopic salivary tissue in the upper cervical region have been described so far.…”

A BSTRACT The majority of the tumours occurring in minor salivary glands are malignant with only 18% being benign. Among the benign tumours, pleomorphic adenoma is the most common. Although it presents more commonly in the parotid and submandibular glands, it can occur at any site where salivary glands reside. Only 6.4% of cases of pleomorphic adenoma occur in minor salivary glands, e.g. palate, cheeks, lips, para-pharyngeal space, etc. It occurs in females in the fourth or fifth decade. It presents as an asymptomatic and slow-growing mass. The treatment of choice is wide local excision due to the high rate of recurrence and malignant potential. We present rare case reports of two patients. The first case is of a young 18 years female presenting with recurrent neck (anterior triangle) swelling and the second case is of a 46-year-old female presenting with lower lip swelling. In both cases, it was a slow-growing mass and asymptomatic. Cytological examination of the lesion revealed the diagnosis of pleomorphic adenoma. It was completely excised with no post-operative complication. Pleomorphic adenoma, although a common benign neoplasm of major salivary glands, should always be kept as a possibility at the locations of minor salivary glands. As pleomorphic adenoma can transform into a malignant counterpart, therefore early diagnosis and treatment of the lesion can prevent further complications. The prognosis of pleomorphic adenoma is excellent. However, a close follow-up of the patient is required due to the high rate of recurrence.

“…The regions involved are submandibular 9 , upper cervical 10,11,12 , subcutaneous plane in lower neck13 region. The symptoms varied from dysphagia and upper airway obstruction to asymptomatic neck mass [9][10][11][12][13] . In our case mass arose from thyroglossal duct presenting as a symptomatic midline neck swelling, which makes it a rare presentation.…”

Introduction: Patent thyroglossal tract commonly appears as a midline neck swelling in form of Thyroglossal cyst. Presentation in form of pleomorphic adenoma has not yet been reported. The aim of this study is to present a case of clinically appearing as thyroglossal cyst which was reported as pleomorphic adenoma of minor salivary gland. Case Report: A 40 year old lady presented with midline neck swelling in suprahyoid region. Welling moved with deglutination and protrusion of tongue. Intraoperatively there was a fibrous band which attached the cyst through the hyoid bone to the tongue. Complete swelling was removed with body of hyoid bone and was sent for histopathology examination (HPE). Results: HPE of the mass revealed pleomorphic adenoma of minor salivary gland arising from thyroglossal duct. Literature search does not show any such evidence of pleomorphic adenoma arising from thyroglossal duct. Conclusion: Midline neck swelling which clinically appears a Thyroglossal cyst may rarely be pleomorphic adenoma.

“…The ectopic salivary gland tissue may be found in other rare sites like external auditory canal, lip, lacrymal glands, hard and soft palate, middle ear, mastoid bone, tongue, tonsils and tonsillar fossa, in the neck. [3][4][5][6][7] Majority of external ear tumors arises from external auditory canal. The finding of a benign mixed salivary tumor in auricle is extremely rare presentation.…”

Pleomorphic adenoma, the most common benign tumor of major salivary glands, may rarely present outside the salivary glands. However, it is extremely rare for these tumors to occur in auricle. We present a case of 40-year-old female with chief complaints of swelling in right pinna in tragal region for 3 years duration with a progressive course. Following inconclusive fine-needle aspiration cytology, excision of the mass was done under local anesthesia. Histopathology report was suggestive of pleomorphic adenoma.
