Synopsis: Malignant Salivary Tumors is rare cancer that forms in tissues of salivary glands on the floor of the mouth and throughout the oropharynx, parotid, and submandibular glands. The salivary glands' cancer commonly presents several histologies: mucoepidermoid, adenoid cystic, acinic cell, malignant mixed, squamous, or adenocarcinoma.

Introduction

Malignant Salivary Tumors Alternate Names: Salivary Glands Cancer, Anaplastic Small Cell Carcinoma of the Salivary Glands, Adenosquamous Carcinoma of the Salivary Glands, Anaplastic Small Cell Carcinoma, Adenosquamous Carcinoma.

Malignant Salivary Tumors is rare cancer that forms in tissues of salivary glands on the floor of the mouth and throughout the oropharynx, the parotid glands, and the submandibular glands.

The U.S. Social Security Administration (SSA) has included Salivary Tumors as a Compassionate Allowance to expedite a disability claim.

Main Item

The salivary glands' cancer commonly presents several histologies: mucoepidermoid, adenoid cystic, acinic cell, malignant mixed, squamous, or adenocarcinoma. Two rare histologies have a much worse prognosis than the standard pathological diagnoses: Anaplastic small cell and adenosquamous carcinoma of the salivary glands.

Anaplastic Small Cell Carcinoma of the Salivary Glands is a neuroendocrine tumor that displays aggressive metastatic behavior. Microscopically, the tumor cells have oval, hyperchromatic nuclei and a scant amount of cytoplasm and are organized in sheets, strands, and nests. At the time of diagnosis, distant metastatic disease is almost always present.

Adenosquamous Carcinoma of the Salivary Glands is an extremely rare malignant neoplasm that simultaneously arises from the surface mucosal epithelium and salivary gland ductal epithelium. The carcinoma shows histopathologic features of both squamous cell carcinoma and adenocarcinoma. In addition to the swelling, adenosquamous carcinoma produces visible changes in the mucosa, including erythema, ulceration, and induration. Pain frequently accompanies ulceration. This carcinoma behaves aggressively with extensive infiltrating local disease and distant metastatic disease.

Symptoms include a lump (usually painless) in the area of the ear, cheek, jaw, lip, or inside the mouth; fluid draining from the ear; trouble swallowing or opening the mouth widely; numbness or weakness in the face and pain in the face that does not go away.

Small cell cancer of the salivary gland and adenosquamous cancer of the salivary gland can be determined only by pathologic evaluation of tissue obtained by needle biopsy or surgery. Additional diagnostic tests may include MRI, CT scan, PET scan, ultrasound, endoscopy, and fine needle aspiration biopsy. After salivary gland cancer has been diagnosed, tests are done to determine if cancer cells have spread within the salivary gland or to other body parts.

Treatment can consist of surgery, radiation, and chemotherapy in various combinations depending on the clinical circumstances. Unfortunately, treatment for small cell carcinoma or adenosquamous carcinoma of the salivary gland is rarely curative.

Progression can be with local recurrence or distant metastases.

Anaplastic Small Cell Carcinoma: Neuroendocrine carcinomas are frequently found in the minor salivary glands. Individuals with this type of cancer have a better survival rate than those with small cell carcinomas of the lung.

Adenosquamous Carcinoma: Limited data indicate a highly aggressive neoplasm with a poor prognosis.
