Adenomyoepithelioma is a proliferation of both epithelial and myoepithelial elements. It is a rare neoplasm first described by Hamperl in 1970 [1]. The term has been used to describe many lesions that are part of a spectrum of changes with myoepithelial prominence occurring in the breast and in other sites. Other lesions in this class include adenoid cystic carcinoma, pleomorphic adenoma, myoep...

Tracheobronchial submucous glands can be considered the pulmonary equivalent of minor salivary glands and therefore they can develop most of the tumours originated in these. Nevertheless, in spite of the wide distribution of this kind of glands along the tracheobronchial tree, pulmonary salivary gland-like neoplasms are not very frequent. Among them, the most frequent are mucoepidermoid and ade...

A 60 year old lady was referred to the Princess Alexandra Hospital (Brisbane, Queensland, Australia) tertiary Otolaryngology, Head and Neck Unit from a peripheral hospital for investigation and management of a tumour at the base of the tongue. Biopsy of the tumour revealed it to be an epithelial-myoepithelial carcinoma of the base of the tongue. This is an extremely rare tumour in this location...

BACKGROUND The most common histological diagnosis of bilateral parotid gland neoplasm is Warthin tumor. Bilateral malignant tumors of the parotid gland are extremely rare. METHODS A 60-year-old man presented with a painless mass in the right preauricular area and an MRI scan showed multiple masses in the parotid glands, bilaterally. A standard superficial parotidectomy was performed on the ri...

Epithelial-myoepithelial carcinoma (EMC) is a rare biphasic tumor accounting for less than 2% of all salivary gland malignancies. It presents as a slowly growing, asymptomatic small size mass, with ulceration of overlying mucosa in some cases. Microscopically, it is characterized by glands lined by the simultaneous presence of two different cell components, inner epithelial cells and outer myoe...

BACKGROUND Epithelial-myoepithelial carcinomas are rare neoplasms usually arising from the salivary glands. There is limited evidence in the literature on their prognosis in the base of the tongue but other cases have resolved without recurrence. METHODS The patient underwent biopsies demonstrating the diagnosis of epithelial-myoepithelial carcinoma of the base of tongue and a PET scan showed...

We present what is believed to be the first report of heterogeneous carcinoma arising from breast ductal adenoma. A 57-year-old woman presented with a nodule in her right breast. Histological examination of a vacuum-assisted biopsy specimen revealed epithelial tubular proliferation and papillary apocrine epithelium. The myoepithelial cells lining the tubules were confirmed by immunohistochemist...
