Pulmonary carcinosarcoma is a rarely encountered tumor. We treated a patient who had an intrabronchial polypoid lesion that required a diagnostic differentiation from epithelial-mesenchymal mixed neoplasms inclusive of pleomorphic adenoma, and that was diagnosed by immunohistochemical staining to be a true carcinosarcoma. A 69-year-old man underwent left pneumonectomy in November 2000 with a di...

Salivary gland tumors are uncommonly seen and account for less than 3% of the head and neck tumors. Pleomorphic adenoma is a well-described benign tumor of the salivary glands, originating from myoepithelial and intercalated duct cells. It is most commonly found in major salivary glands. We present a rare and unusual case of pleomorphic adenoma of the minor salivary glands in the lower lip. The...

INTRODUCTION Pleomorphic adenoma accounts for 65 percent of all salivary gland tumors. It has been identified in several anatomical regions, but pleomorphic adenoma arising in the ear canal, first described in 1951, is extremely rare. CASE PRESENTATION A 40-year-old Japanese man's left ear canal was obstructed by a pleomorphic adenoma that caused mild conductive hearing loss. The tumor was re...

Pleomorphic adenoma is the most common benign tumour of major salivary gland presenting as a painless mass gradually increasing in size, usually involving parotid gland. In minor gland, it more palate. lip rare tumour. Thus, we present case pleomorphic originating from upper 75 years old male patient. The tumor was completely excised and sent for histopathological examination which showed micro...

BACKGROUND Metastasizing pleomorphic adenoma is an uncommon malignant tumor of the salivary gland demonstrating benign epithelial and modified myoepithelial elements intermingling with tissue of mucoid, myxoid, or chondroid appearance that inexplicably manifests local or distant metastasis. OBJECTIVE To determine the expression of hormonal receptor in the patients with metastasizing pleomorph...

Pleomorphic adenoma (PA), also known as mixed tumor, is the most common benign salivary gland neoplasm, characterized histologically by both epithelial and mesenchymal elements. Approximately 75% of PAs occur in the parotid gland, followed by the submandibular gland (15%) and minor glands of the palate and nasal septum (10%). Less common is the occurrence in the minor glands of the upper lip, c...

Pleomorphic Adenoma is a benign epithelial tumor arising from the salivary gland. It is a benign mixed tumor composed of epithelial and myoepithelial cells arranged with various morphological patterns, demarcated from surrounding tissues by fibrous capsule. In this article, we report an unusual case of 30 year, male with a single, nodular swelling evident in the upper lip which was discovered d...

INTRODUCTION Pleomorphic adenoma is the most common benign neoplasm of the salivary glands. Extensive lipomatous involvement of the tumor is, however, a very rare finding. CASE REPORT Herein, a rare case of lipomatous pleomorphic adenoma arising in the parotid gland of a 14-year-old Japanese woman is presented. CONCLUSION This is the sixth case of lipomatous pleomorphic adenoma in the Engli...

Pleomorphic adenoma is the most common neoplasm of the parotid gland. It is associated with the risk of recurrence and malignant transformation. Tumor spillage, incomplete excision, and violation of the tumor pseudocapsule are considered the only proven factors contributing to recurrent disease. The upward spread of recurrent pleomorphic adenoma along the fallopian canal via the stylomastoid fo...
