Question 1

Q: Which of the following statements is not correct regarding sebaceous cyst?

Treatment is incision and drainage. ***Treatment is incision and drainage*** - The standard treatment for a sebaceous cyst (more accurately an **epidermoid cyst** or **pilar cyst**) is **surgical excision** of the entire cyst wall to prevent recurrence. - **Incision and drainage** only provides temporary relief by emptying the contents but leaves the cyst wall intact, leading to a high chance of the cyst refilling. *Found on hairy areas of the body* - This statement is generally correct as sebaceous cysts often arise from hair follicles and are common in **hair-bearing areas** like the scalp, face, neck, and trunk. - They occur due to the accumulation of **sebum** and keratin within a blocked or damaged sebaceous gland or hair follicle. *Not found on palms and soles* - This statement is correct because **palms and soles** generally **lack sebaceous glands** and hair follicles, hence sebaceous cysts are typically not found in these locations. - Cysts found in these areas are more likely to be **ganglion cysts** or other types of epidermal inclusion cysts. *It has a punctum* - This statement is often correct; many sebaceous cysts (especially epidermoid cysts) have a visible **central punctum** which represents the occluded pore from which the cyst originated. - This punctum is a **key diagnostic feature** and can sometimes exude a cheesy, foul-smelling material.
