Granular cell tumour on vaccination scar in a young girl

Abstract

Granular cell tumors originate from neural elements. These distinctly rare tumors usually appear as solitary nodular growths and run a benign course. Although internal organs are rarely involved, skin and oral cavity are the commonest sites of affection. Their peak occurrence is in middle age. We present a case of a large solitary granular cell tumor occurring on the upper arm of a young girl at the site of a vaccination scar. Histopathology showed sheets of polyhedral cells with indistinct cell boundaries containing abundant eosinophilic fine granules. Excision of the lesion appeared to have cured the condition.
