INTRODUCTION: Palisaded encapsulated neuroma (PEN) is a benign lesion of Schwann cells and its occurrence in the oral mucosa especially the tongue is very rare. CASE REPORT: This article describes a case of a 41-year-old male, a chronic smoker with an actively bleeding, ulcerated, solitary, firm lesion on the lateral border of the tongue which had bled thrice before. A differential diagnosis of pyogenic granuloma, haemangioma, fibroma, nerve sheath tumour, salivary gland tumour and malignancy was made and surgically excised. Histopathology of the excised specimen revealed a well-circumscribed lesion with spindle-shaped cells arranged in interlacing fascicles and with the help of immunohistochemical markers confirmed it to be a PEN. DISCUSSION: To our knowledge, this is the first description of an ulcerated PEN presented with an active bleed.
