HistoryThis section has been translated automatically.

Abrikossoff, 1926

DefinitionThis section has been translated automatically.

Descriptive term for a series of rare, heterogeneous, predominantly benign tumors that are characterized by the predominant occurrence of granular cells. In the skin and in the mucous membranes close to the skin, most granular cell tumours are of neurogenic origin and also show a close relationship morphologically to peripheral nerves. Clinically, the tumors are uncharacteristic. Thus, the diagnosis is usually an incidental finding.

ManifestationThis section has been translated automatically.

Mostly occurring in women (20.-60. LJ). Rarely from birth or in children and adolescents.

LocalizationThis section has been translated automatically.

Occurrence is possible on the whole integer. The tongue, lips, thorax and extremities are frequently affected (Tobouti PL et al. 2017). Infection of internal organs is possible.

Clinical featuresThis section has been translated automatically.

Solitary, pea-sized, coarse, skin-coloured or reddish-yellow tumour. Multiple occurrences are also known. Occasional occurrence of superficial leukoplakia.

HistologyThis section has been translated automatically.

  • Mostly a compact tumour penetrating the entire dermis with nests and strands of oval to polygonal, distended cells with eosinophil granulated cytoplasm. The cell nuclei are usually small and pynotic and are located in a decentralized position. A characteristic feature of granular cell tumors is a clearly acanthotic, orthokeratotic surface epithelium covering the tumor parenchyma.
  • Immunohistochemistry: Tumor cells are positive for S100, neuron-specific enolase and myelin basic protein, among others.

Differential diagnosisThis section has been translated automatically.

TherapyThis section has been translated automatically.

Excision without significant safety distance.

Progression/forecastThis section has been translated automatically.

Favourable, very rarely malignant degeneration (1-2%). In case of multiple infestation clinical control examinations.

Note(s)This section has been translated automatically.

Originally, Abrikossoff described the granular cell tumors as myogenic tumors. It was not until 23 years later that the Austrian pathologist Feyrter was able to prove their neurogenic genesis. Today, the tumors are considered to be a variant of schwannoma.
