Sebaceous hyperplasia
Sebaceous hyperplasia is a disorder of the sebaceous glands in which they become enlarged, producing flesh-colored or yellowish, shiny, often umbilicated bumps on the face. Sebaceous hyperplasia generally affects middle-aged to elderly adults. The symptoms are 1–5 mm papules on the skin, mainly on the forehead, nose and cheeks, and seborrheic facial skin.

#Pinhole technique (Erbium or CO2 laser)
  • Appears as flesh-colored papules, but it differs from basal cell carcinoma in that it is soft to the touch.
  • Multiple sebaceous hyperplasias on the forehead. ― A typical case.
  • It can be difficult to distinguish from basal cell carcinoma based solely on appearance, but can be accurately differentiated by touching the lesion.

[Pinhole Technique] A 15-year-old boy presented with a CALM on his cheek. We performed 6 sessions of pinhole treatment every 4 weeks using erbium : YAG laser set to a continuous wave mode with a spot size of 1 mm. The lesion showed marked improvement with mild erythema, and there was no recurrence at the 12-month follow-up. A 55-year-old female presented with a 10-year history of telangiectasia on the right cheek. The telangiectasia was treated using the pinhole method using a CO2 laser. Multiple small holes, measuring 1 mm in diameter, were made down to the papillary dermis. These holes were made approximately 3 mm apart all over the telangiectasia area. The telangiectasia showed significant improvement after 1 treatment session. No recurrence was noted at the 3-month follow-up.
