Microscopic Diagnosis

We report a palatal mucoepidermoid carcinoma (MEC) with unusual pathological features showing salivary duct cyst-like architecture, varied epithelial linings (excretory duct, mucous goblet cell, and apocrine epithelium phenotypes), scarce luminal tumor plaques, and a large intraluminal oncocytic polyp. To our knowledge, such a unicystic variant of MEC with pedicled oncocytic proliferation in the lumen is unprecedented in the literature. In this particular case, the microscopic diagnosis of MEC is problematic because of the large number of potential mimics.

Histopathologic Features

Non-neoplastic cysts of the salivary glands are uncommon and represent 2-5% of all salivary gland lesions. They are mainly mucoceles or salivary duct cysts. Unlike a mucocele, which is surrounded by granulation tissue, the salivary duct cyst is lined by epithelium. Salivary duct cysts are more common in the oral minor salivary glands and rarely occur in the major salivary glands, show a marked predilection for the superficial lobe of the parotid, and represent 10% of all salivary gland cysts. Neoplastic differentiation of the lining of the salivary duct cyst has been reported. We report a case of a salivary duct cyst of the left parotid gland, with a review of radiographic and histopathologic features.

Salivary Duct Cyst

The clinical and radiological differential diagnosis of cystic lesions of the submandibular region can be difficult. We report an unusual case of a submandibular salivary duct cyst mimicking an external laryngocele on presentation by appearing to expand on Valsalva manoeuvre, and where computed tomography (CT) scanning was unhelpful in reaching a diagnosis. We present the case, discuss the theories of pathogenesis, and review the literature on the differential diagnosis of cystic lesions in the submandibular region.
