Granular cell tumors and chordomas are also found.

Granular cell tumors are typically solitary and are rarely larger than three centimeters.

Some investigators have found that granular cell tumors have a worse prognosis, but this finding is not universal.

Granular cell tumors are also found in the internal organs, particularly in the upper aerodigestive tract.

It is important to separate hiberoma from adult rhabdomyoma, a granular cell tumor and a true liposarcoma.

Granular cell tumor is a tumor that can develop on any skin or mucosal surface, but occurs on the tongue 40% of the time.

When the resection margins of a benign granular cell tumor are positive for tumor infiltration the recurrence rate is increased to 20%.

Granular cell tumors show similarity to neural tissue, as can be demonstrated by immunohistochemistry and ultrastructural evidence using electron microscopy.

Benign granular cell tumors have a recurrence rate of 2% to 8% when resection margins are deemed clear of tumor infiltration.

This type of tumor has been found to be both benign and malignant, although malignancy is rare and comprises only 2% of all granular cell tumors.

The differential diagnosis histologically includes rhabdomyosarcoma, granular cell tumor, alveolar soft part sarcoma, hibernoma, oncocytoma, and crystal storing histiocytosis, among others.

Pathological conditions of the tongue include geographic tongue, burning mouth syndrome, tongue necrosis, oral hairy leukoplakia, granular cell tumor and squamous cell carcinoma.

Multiple granular cell tumors may seen in the context of LEOPARD syndrome, due to a mutation in the PTPN11 gene.

Other tumors that arise in the pituitary include craniopharyngiomas, meningiomas, and germ cell tumors; the rare granular cell tumors, pituicytomas, and gangliogliomas; and the even rarer gangliocytomas, lymphomas, astrocytomas, and ependymomas.

It is also known as Abrikossoff's tumor, Granular cell myoblastoma, Granular cell nerve sheath tumor, and Granular cell schwannoma.)
