Pleomorphic Adenoma in a Posterior Cervical Soft Tissue Mass: A Diagnostic Conundrum.

Diagnosing a soft tissue tumor in the head and neck region can be challenging due to its complex anatomy and diverse histological spectrum. This case report highlights the case of a woman who presented with a painless neck lump in the posterior triangle of the neck. Various pathological and imaging studies were suggestive of pleomorphic adenoma, which arises from the left prevertebral space. The patient underwent complete surgical excision via the transcervical approach. Pleomorphic adenoma in the posterior triangle of the neck is extremely rare and causes a diagnostic dilemma in managing soft tissue tumors of the neck.

A Rare Case of a Nasopharyngeal Pleomorphic Adenoma Mimicking a Nasopharyngeal Carcinoma.

Pleomorphic adenoma is the most common benign pathology of the major salivary gland but rare in the minor salivary gland, especially in the nasopharynx, with only a few cases reported in the literature. A 76-year-old lady presented with bilateral nasal blockage for one year secondary to a nasopharyngeal mass. Histopathological examination reported it to be nasopharyngeal carcinoma, but the mass persisted after a course of chemotherapy combined with radiotherapy. Upon repeat biopsy, the mass was found to be a pleomorphic adenoma. The patient underwent nasopharyngectomy without complications and no evidence of recurrence after 18 months of follow-up.
