Question

A 40-year-old male patient presents with a swelling that has been slowly growing in the past 2 years. On examination, it was variable in consistency and fully mobile. What is the most likely diagnosis?

• A. Dermoid cyst
• B. Parotid tumor
• C. Sebaceous cyst
• D. Cervical lymph node

Answer 1

The Correct Option is B

A 40-year-old male patient presents with a swelling that has been slowly growing over the past 2 years. It's variable in consistency and fully mobile on examination. We need to determine the most likely diagnosis from the given options. Let's analyze each option to identify the correct diagnosis:

• Dermoid cyst: Typically found in young adults, dermoid cysts are non-mobile, solid, and often located in areas of embryonic fusion. The mobility and variable consistency described do not align well with characteristics of dermoid cysts.
• Parotid tumor: Parotid gland tumors, such as pleomorphic adenomas, are often mobile and can have varying consistencies due to their mixed cellular content. Given the history of slow growth, mobility, and variable consistency, a parotid tumor is a strong candidate.
• Sebaceous cyst: These cysts are usually superficial, firm, and do not typically exhibit variability in consistency. They are often associated with an overlying skin punctum and show less mobility.
• Cervical lymph node: Enlarged lymph nodes are often firm and may occur in response to infection or other systemic conditions. The slow growth and degree of mobility make this less likely compared to a parotid tumor.

Based on the characteristics described, the most likely diagnosis is a Parotid tumor due to its alignment with the observed features: slow growth, mobility, and variable consistency.
