Multiple localization of granular cell tumour: a case report

INTRODUCTION: Granular cell tumour, also known as Abrikossoff's tumour, is a rare entity occurring in the skin as well as in internal organs, more common among the third to fifth decade of life. It has often been described as a peripheral neuroectodermal tumour and its clinical behaviour is usually benign although malignant and multifocal forms are also known to occur. CASE PRESENTATION: We report a case of multiple granular cell tumour in a 17-year-old Caucasian woman who presented with a nodular lesion in the popliteal cave, diagnosed as an Abrikossoff's Tumour, followed 2 years later by another soft tissue mass in the neck. CONCLUSION: This case is quite rare: only a few cases were presented in literature with an extended period of time before the clinical presentation of subsequent disease.
