A 56 year old smoker presented with swelling over parotid region. Histology shows papillary structures composed of granular eosinophilic cells, cystic changes, and mature lymphocytic infiltration which is pathognomonic of Wahin tumor. Treatment of choice for wahin’s tumor is:
**Core Concept**
Wahin's tumor, also known as Warthin tumor, is a benign salivary gland neoplasm that primarily affects the parotid gland. It is characterized by papillary structures composed of granular eosinophilic cells, cystic changes, and mature lymphocytic infiltration, which are pathognomonic features.
**Why the Correct Answer is Right**
The treatment of choice for Warthin tumor is surgical excision, specifically a superficial parotidectomy. This approach involves the removal of the tumor along with a margin of normal tissue to ensure complete excision. The lymphocytic infiltration in Warthin tumor is a characteristic feature that helps differentiate it from other salivary gland tumors, such as pleomorphic adenoma or adenoid cystic carcinoma.
**Why Each Wrong Option is Incorrect**
**Option A:** Radiation therapy is not the primary treatment for Warthin tumor, as it is a benign neoplasm and does not require adjuvant therapy. While it may be used in some cases, it is not the first line of treatment.
**Option B:** Fine-needle aspiration cytology (FNAC) may be used to diagnose Warthin tumor, but it is not a treatment option. FNAC is a diagnostic tool that helps identify the tumor type and guide further management.
**Option C:** Chemotherapy is not indicated for Warthin tumor, as it is a benign neoplasm that does not require systemic treatment. Chemotherapy is typically reserved for malignant tumors that have spread beyond the primary site.
**Clinical Pearl / High-Yield Fact**
Warthin tumor is a benign salivary gland neoplasm that is strongly associated with smoking. Patients with a history of smoking are at higher risk of developing Warthin tumor, making it an important consideration in the differential diagnosis of parotid gland masses.
**Correct Answer:** C.
