A 65-year-old female patient reported with a chief complaint of swelling in the left lower region of the jaw since two years. On clinical examination, the swelling was present on the mandibular left posterior region and measuring approximately 6.2 cm antero-posteriorly × 6.2 cm mediolaterally × 8.7 cm superioinferiorly. Initially, it was non tender but eventually it became tender. Fine needle aspiration was done to rule out any salivary gland pathology and report obtained was carcinoma ex pleomorphic adenoma. Then, excisional biopsy was taken and tissue sent for histopathology. Histopathological diagnosis was benign adenoma with carcinoma. Later serial sections of tissue were studied and came to the conclusion of carcinoma ex pleomorphic adenoma which was non invasive type and showed bizarre cells with neoplastic changes. Benign part was composed of myxomatous area with partial capsule. Neoplastic cells showed invasion into capsule and few necrotic areas were also present. Overall interpretation was favoured Non invasive carcinoma ex pleomorphic adenoma. So here, we reported a case of Carcinoma ex Pleomorphic Adenoma (CAEXPA) which is a deadly and rare variant of salivary gland malignancy.
