Histologic Subtype

ABSTRACT Carcinoma ex-pleomorphic adenoma (CaxPA) is a carcinoma arising from a primary or recurrent benign pleomorphic adenoma (PA). It presents approximately 11.6% of all malignant neoplasms of salivary gland and mostly originates from major salivary glands. It is a common histologic subtype of primary parotid malignancy. Location in the minor salivary gland is uncommon and occurs in less than 7% of all cases. The majority of CaxPA develops from epithelial component of PA. Salivary gland tumors are known to have a benign clinical behavior with unrecognized metastatic potential. It often poses a diagnostic challenge to clinicians and pathologists. The entity is difficult to diagnose preoperatively. Pathologic assessment is the gold standard for making the diagnosis. We present a case of a 55-year-old female patient who had a right preauricular mass of 10 years duration, with sudden onset of pain of duration of 1 month.

Pertinent Literature

AbstractThe presence of melanin pigment and melanocytic markers expression have been rarely reported in salivary gland tumors. Herein, two cases of carcinoma arising in pleomorphic adenoma of the parotid gland and showing diffuse expression of myoepithelial and melanocytic markers are described. The clinical-pathological clues useful in the differential diagnosis with melanoma are discussed. In addition, a review of the pertinent literature is also proposed, discussing the pathologic mechanisms potentially involved in this phenomenon.
