This 49 year old man attended PCSS with a 3 month history of swelling at the occipital region (back) of his head, that has been increasing in size over time, and causing some discomfort.
On examination of this area, there was slight redness of the overlying skin, and on palpation, a slightly mobile subcutaneous swelling was noted, which was non-tender (Photo 1).
A vertical incision 🔪 was made over the swelling and this lesion was removed, and the wound 🪡(Photo 2).

Answer - A PILAR CYST (OR TWO!)
Photo 3 shows the first cyst being teased out with applying pressure on the skin around it.
Photo 4 shows the ✌️cysts, attached by some connective tissue.
⭐️ FUN FACTS ABOUT CYSTS ⭐️
1. Pilar cysts are common lesions that can be found in areas of the body that have hair - usually the scalp.
2. These cysts are made up of a sac, that is filled with a fluid/semi-fluid 🧀-looking material that is made up of soggy keratin, a type of protein that is found in hair, nails and skin.
3. Sometimes, these cysts can pop by themselves when they get too big, or from trauma ie. combing, brushing, scratching, and you can expect some discharge of its foul-smelling contents! 👃☹️
TAKE HOME MESSAGE! 👇👇
While most pilar cysts are small and not bothersome, sometimes they may require removal, and indications for this are:
INCREASING SIZE/DISCOMFORT - cysts can increase in size over time, and can discomfort/pain due to its size and position
INFECTION - cysts can also become infected occasionally, requiring antibiotics to treat the acute infection, and some people may get recurrent infections
COSMETIC - they can be unsightly, and can cause hair loss of the overlying scalp skin when it becomes larger
