A case of salivary gland type pleomorphic adenoma of the trachea in a 48-year-old woman is presented. Pleomorphic adenoma is extremely rare in the trachea. The behavior of this tumor in the trachea appears to be similar to its counterpart in other sites and distinctly different from the more frequently encountered epithelial tumors.

Pleomorphic xanthoastrocytomas (PXAs) are rare neoplasms comprising less than 1% of all astrocytic tumors, World Health Organization (WHO) grade II glial tumour.

The most common benign salivary gland tumor is pleomorphic adenoma. They can attain giant proportions and weigh several kilograms. They can cause facial disfigurement and, if untreated, could lead malignant transformation. This image depicts a 7.5 kg pleomorphic adenoma of right submandibular gland with malignant change in a 55-year-old male.

Pleomorphic lipomas are rare benign tumours that can resemble a variety of malignant tissue tumour on histological examination. We describe a case of pleomorphic lipoma arising on the posterior aspect of the neck of a 70-year-old man, successfully treated by surgical excision. A review of the literature is presented, summarizing the principal clinical and morphological characteristics of this r...

The occurrence of multiple distinct tumors in major salivary glands is quite rare. Although the most common tumor with bilateral synchronous or metachronous development is the Warthin's tumor, pleomorphic adenomas have been very rarely diagnosed simultaneously as well. The authors report two consecutive cases of patients with bilateral pleomorphic adenomas of the parotid glands discussing clini...

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...

Abstract Background Pleomorphic adenoma, also known as a benign mixed tumor, is the most common salivary gland tumor. The parotid accounts for 90% of total, with minor glands accounting 10%. Buccal pleomorphic adenoma extremely rare. It manifests painless, firm, slow-growing mass in cases. Case presentation A buccal was discovered an adult 43-year-old female patient treated wide surgical resect...

The pleomorphic adenoma, also known as mixed tumor, presents an epithelial and mesenchymal histological structure, being also called epithelioma with altered stroma. The pleomorphic adenoma has a frequency of 70% of major salivary gland tumors, being located preponderantly at the level of parotid gland (52-84%), at the level of submandibular glands (7-17%) and at the level of the other salivary...

A 61-year-old female was referred to The First Affiliated Hospital, College of Medicine, Zhejiang University (Hangzhou, China) due to a right adrenal tumor. A pre-operative transcutaneous fine-needle aspiration biopsy and right adrenalectomy were performed, and pathological analysis resulted in the diagnosis of pleomorphic rhabdomyosarcoma (RMS). Primary pleomorphic RMS of the adrenal gland in ...

We report here a case of thymoma simultaneously associated with undifferentiated pleomorphic sarcoma. A 45-year-old male presented with axillary lump. Radiographic studies showed a mediastinal mass. On fine needle aspiration cytology and histopathological examination, a diagnosis of thymoma with coexisting undifferentiated pleomorphic sarcoma was made. Although thymomas are associated with many...
