Background: Pleomorphic adenoma is the most common benign tumor of the parotid gland. Although surgical excision is usually curative, recurrence may occur due to incomplete removal or microscopic residual tumor, necessitating careful long-term follow-up. Case Presentation: A 50-year-old male presented with a gradually enlarging, painless swelling below the left ear lobule that had been increasing in size over one year. The patient had undergone surgical excision of a similar swelling at the same site four years earlier. Clinical examination revealed a firm, well-defined, 10 × 6 cm mass in the left parotid region with a previous surgical scar, upward displacement of the ear lobule, and no evidence of facial nerve palsy or cervical lymphadenopathy. The lesion was surgically excised. Discussion: Histopathological examination demonstrated a well-circumscribed tumor composed of epithelial, myoepithelial, and stromal components with characteristic tubular and acinar structures embedded in a myxoid stroma, confirming recurrent pleomorphic adenoma of the parotid gland. The absence of facial nerve involvement and lymph node enlargement supported the benign nature of the lesion. Conclusion: This case highlights the potential for recurrence of pleomorphic adenoma following surgical treatment. Complete surgical excision with preservation of the facial nerve and long-term postoperative surveillance are essential to minimize recurrence and ensure favorable patient outcomes.

tion 4 years back which had been operated then. He had no pain over the swelling and no history suggestive of facial nerve paralysis. On examination, there was a firm swelling in the right parotid region 10 cm × 6 cm in size, with a smooth surface except for a scar denoting previous surgical excision, well defined and rounded margins, free from the skin and underlying structures.

in between the posterior border of the mandible and the mastoid process. There was no evidence of facial nerve palsy. There were no palpable lymph nodes in the neck. History and clinical examination suggested this to be a benign tumor. The tumor was excised. Histopathological evaluation of the specimen confirmed the diagnosis of pleomorphic adenoma of the parotid gland (Figure 2).
