How rare is a granular cell tumor?
Background: Granular cell tumors (GCTs) or Abrikossoff’s tumors are rare neoplasms known to originate from Schwann cells in the peripheral nervous system. These lesions are usually benign; malignancy only occurs in 1–2% of cases.
What does a granular cell tumor feel like?
A granular cell tumor of the breast can most often be felt as a firm lump that you can move, but some may be attached to the skin or chest wall. They are most often in the upper, inner part of the breast.
Do granular cell tumors grow?
Granular Cell Tumours are rare mesenchymal soft tissue tumours that arise throughout the body and are believed to be of neural origin. They often present as asymptomatic, slow-growing, benign, solitary lesions but may be multifocal.
Is a granular cell tumor cancer?
Most granular cell tumors are benign (not cancer), but some may be malignant (cancer) and spread quickly to nearby tissue. They usually occur in middle-aged adults. Also called Abrikossoff tumor.
How do you get rid of a granular cell tumor?
Treatment is with surgical resection. With benign granular cell tumors, local surgical excision is curative, if complete resection is achieved; however, recurrence is possible even withclear margins. Wide en bloc excision is recommended for malignant lesions.
Is granular cell tumor hereditary?
GCTs may be part of some genetic syndromes , such as LEOPARD syndrome and neurofibromatosis. Complete surgical removal of the tumor is usually curative, but in some cases the tumors may recur.
Is a granular cell tumor encapsulated?
Granular cell tumor (GCT) is a rare tumor (Figure 1) and rarely diagnosed prior to histopathological examination of (Figure 2) the biopsy or excised specimen. The GCTs are usually poorly circumscribed and non-encapsulated.
Are granular cell tumors painful?
These neoplasms are now considered to be of neural origin. The tumor is usually asymptomatic although some patients may experience mild pruritus or pain. A case of a large solitary painful GCT is reported here for its rarity.
What causes granular cell tumor tongue?
Various theories on the origin of GCT have subsequently been proposed, including its origin from striated muscle and histiocytes and a neural origin. Granular cell tumors can affect any organ or region of the body. Most GCTs occur in the head and neck region, especially in the tongue, cheek mucosa, and palate .
Are all granulosa cell tumors malignant?
GCTs are thought to be tumors of low malignant potential. Most of these tumors follow a benign course, with only a small percentage showing aggressive behavior, perhaps due to early stage at diagnosis. Metastatic disease can involve any organ system, although tumor growth usually is confined to the abdomen and pelvis.
Is fibroma malignant?
They can grow in all organs, arising from mesenchyme tissue. The term “fibroblastic” or “fibromatous” is used to describe tumors of the fibrous connective tissue. When the term fibroma is used without modifier, it is usually considered benign, with the term fibrosarcoma reserved for malignant tumors.
