Summary
A rare case of a keloid scar developing over a pleomorphic adenoma in the parotid gland is presented. This unusual co-occurrence highlights the importance of thorough investigation for parotid masses.
Area of Science:
- Dermatology
- Otolaryngology
- Surgical Pathology
Background:
- Keloids are benign fibrous growths that can arise after skin injury.
- Pleomorphic adenoma is the most common benign tumor of the salivary glands, particularly the parotid gland.
Observation:
- A 37-year-old woman presented with a 13-year history of an itchy, painful scar on her left parotid region, originating from an acne lesion.
- Examination revealed a keloid overlying a firm, nontender mass in the parotid area.
- Imaging and cytology suggested a benign parotid tumor.
Findings:
- Histopathological examination of the resected superficial parotidectomy specimen confirmed a keloid overlying a pleomorphic adenoma.
- This represents an uncommon association between a keloid and a parotid gland tumor.
Implications:
- This case underscores the importance of considering underlying pathology when evaluating persistent or unusual cutaneous findings, even in benign-appearing lesions.
- The co-presentation of a keloid and pleomorphic adenoma is rare and warrants further investigation into potential pathogenetic links or coincidental occurrence.
