Pleomorphic adenoma is the most common benign salivary gland tumour. It can occur in any salivary gland, but is most frequently found in the parotid gland. Chondroid metaplasia is a frequent finding in pleomorphic adenoma. Other forms of metaplasia have been described, but are encountered less frequently. We report a rare case of unusual pleomorphic adenoma of the parotid gland with schwannoma-...

Among salivary gland neoplasms, metastasizing pleomorphic adenoma (MPA) constitutes an extremely rare group of tumors. The present paper reports a case of pleomorphic adenoma (PA) in submandibular gland that, after more than 30 years of initial treatment, recurred and metastasized to ipsilateral neck lymph nodes and parotid gland. In an attempt to elucidate the malignant behavior of metastasizi...

Among neoplasia of head and neck, Salivary gland tumours are rare it comprises about less than 3%.Pleomorphic adenoma is the most common benign tumour all salivary tumours, which so called mixed due its wide cyto-morphological architectural diversity. In this case report we presenting a pleomorphic buccal mucosa in 56 year old male patient who reported to our department with complaint pain swel...

Pleomorphic xanthoastrocytoma (PXA) is rare primary neoplasm of brain. Despite its pleomorphic appearance, it has a relatively good prognosis. We report a case of biopsy proven pleomorphic xanthoastrocytoma in a young male who presented with visual and sensory symptoms, classical neuroimaging findings and showed remarkable recovery, post surgery. We have also reviewed recent literature focusing...

OBJECTIVE This study aimed to characterize alteration in the immunohistochemical expression of p16 in normal tissue of the salivary gland surrounding pleomorphic adenoma, and the tumor cells of pleomorphic adenomas. MATERIAL AND METHOD A selected series of 120 cases of pleomorphic adenomas were examined. RESULTS The results showed that p16 expression in non tumor duct cells was strong posit...

Pleomorphic giant cell carcinoma of the pancreas usually has a very poor prognosis with some investigators reporting a mean post-surgical survival time of just months. This poor post-surgical prognosis has led to the reappraisal of the use of surgical resection for pleomorphic carcinoma. Rcently, this carcinoma is classified as a type of anaplastic ductal carcinoma by Japanese criteria 2002. We...

When oncologists encounter patients with pulmonary pleomorphic carcinoma, most cases have recurrent disease after surgery or metastatic disease. Previous studies have suggested that patients with pleomorphic carcinoma have extremely poor responses to chemotherapy regimens commonly used for non-small cell lung cancer and have a dismal prognosis. This report describes two consecutive patients wit...

Rhabdomyosarcoma is a malignant neoplasm of primitive mesenchyme exhibiting skeletal muscle differentiation. Rhabdomyosarcoma, which can histopathologically be of embryonal, alveolar, botryoid and pleomorphic types; is a rare tumor in children, with an annual incidence of 4.3 cases per million. Pleomorphic rhabdomyosarcomas is a rare variant, occurring more commonly in adults. We report a rare ...

BACKGROUND Head and Neck Parapharyngeal space tumors are rare. Pleomorphic Adenomas are the most common Parapharyngeal space tumors. The purpose of this study was to define preoperative criteria for enabling full extirpation of parapharyngeal space pleomorphic adenomas via the transcervical approach while minimizing functional and cosmetic morbidity. METHODS The surgical records and medical c...

Pleomorphic adenomas with a nuclear palisading arrangement of spindle-shaped modified myoepithelial cells (MMCs), suggesting the appearance of palisading leiomyoma or Antoni's A type of neurilemmoma, are quite rare, and its cytologic nature has been poorly understood. This paper reports histologic and immunohistochemical findings of palisading MMCs in two cases of pleomorphic adenoma. Histologi...
