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.

Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
