Abstract
The occurrence of a second malignant neoplasm (SMN) in patients who have been submitted to kidney transplantation is increasing and causes concern; parotid carcinoma is rarely reported after transplantation and may be related to long-term chemotherapy.Salivary gland carcinomas displaying exclusively myoepithelial differentiation—myoepithelial carcinomas (EMC) are rare, being less than 1% of all salivary gland tumours. EMC arises most commonly in the parotid gland and usually occurs in women. Their histopathologic features, immunohistochemical profile and clinical behaviour remain controversial.
Highlights
We here report a case of exclusively myoepithelial differentiation—myoepithelial carcinomas (EMC) occurring in a 74-year-old man, 14 years after chemotherapy, following kidney transplantation due to chronic renal failure
In 1985, Barnes et al reviewed the literature of all myoepitheliomas of the head and neck and found only three cases
A recent study [6] summarizing new findings on salivary gland pathology has included the morphological spectrum of epithelial-myoepithelial carcinoma and variants
