Hi! thanks for your question posted on HCM! After going through the history and short description of the lesion on your inner thigh, I feel, if I were your physician would like to consider/suggest followings: 1. sebaceous cysts are best treated by surgical excision only; as the contents once spilled out can initiate foreign-body reaction and recurrent abscess formation, it is always best to remove it before it is partially or completely ruptured or punctured! the remains of cyst wall, if any, can also create new cysts in the surroundings...! 2. the cyst, when aged enough, gets black in colour due to silent accumulation of blood components and melanin of the skin 3. once this is squeezed, the content comes out; it could be blood mixed pus, pultaceous/chalky material, fluid etc and leaves the cyst open to the environment thereby recurrent infection! 4. normal bleeding time is 2-5 minutes so this was normal and always apply pressure to reduce blood loss 5. never ever squeeze or poke this but see a general surgeon as this might cause you major impairments due to severe infection! regards!
