[|Human|] My wife has developed a flat oval painless lump on her forehead below her hairline. The It is hard to tell if it is on or in the frontalis muscle and she thinks it is gradually enlarging. The skin over it looks normal with no sign of inflammation and she thinks this started a little over a year ago. I have her seeing our physician next week, but I was wondering if you had any thoughts as to what this may be. A cyst or developing lipoma?
[|AI|]  Hello! Welcome to Chat Doctor. This can be a Desmond if in midline (center).Also, it can be a lipoma or sebaceous cyst. If very hard in consistency, then it can be an asteroid Osceola. All are benign swellings. In my clinic, to such patients, I advise X-ray skull to rule out any intracranial extension.FNAC - fine needle aspiration cytology is advisable for diagnosis if in doubt on clinical examination. If there is no intracranial extension, then excision biopsy is done i.e. swelling is removed & sent for histopathological examination. Complete removal of cyst along with its wall is important, as if any part of cyst wall remains behind, then recurrence will be there. Hope this helps. Wish you healthy life. Thanks. Regards.
