Alternate Names: Salivary Glands Cancer, Anaplastic Small Cell Carcinoma of the Salivary Glands, Adenosquamous Carcinoma of the Salivary Glands, Anaplastic Small Cell Carcinoma, Adenosquamos Carcinoma

Cancer of the salivary glands commonly presents with one of several different histologies: mucoepidermoid, adenoid cystic, acinic cell, malignant mixed, squamous or adenocarcinoma. There are two rare histologies which have 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 which displays very aggressive metastatic behavior. Microscopically, the tumor cells have oval, hyperchromatic nuclei and scant amount of cytoplasm and are organized in sheets, strands, and nests. At 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 surface mucosal epithelium and salivary gland ductal epithelium. The carcinoma shows histopathologic features of both squamous cell carcinoma and adenocarcinoma. In addition to 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 as well as 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 find out if cancer cells have spread within the salivary gland or to other parts of the body.

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 compared to those with small cell carcinomas of the lung.

Adenosquamous Carcinoma - Limited data indicate that this is a highly aggressive neoplasm with a poor prognosis.
