Abstract:
The differential diagnoses of neck mass may include a wide spectrum of lesions ranging from cysts, inflammatory processes, benign and malignant tumors arising from skin, soft tissue, lymph nodes, endocrine glands, salivary glands to metastatic tumors. In adults, malignant non-thyroid neck masses are often metastatic squamous cell carcinoma. Gynecomastia, presenting as a mass or enlargement in its typical subareolar location is usually a straightforward diagnosis. Enlargement due to gynecomastia in locations other than subareola can pose diagnostic challenge. We describe a unique case of gynecomastia presenting as a neck mass in a patient who was diagnosed and treated for squamous cell carcinoma of the floor of the mouth.
