Lichen planopilaris - misdiagnose? Could my hair loss be related to the treatment?

The only way to properly diagnose LPP is for a clinician to know everything about the patient’s story and review the scalp up close (with magnification techniques known as trichoscopy). In your case, we don’t have photos so it’s impossible to fully answer the question in the manner it so deserves. Your biopsy information has features of LPP but alot of information is missing. Your information here does not necessarily mean it’s LPP just that it’s possible. LPP often has loss of sebaceous glands and early LPP had death of keratinocytes in the outer root sheath. This information is missing from the information given so one needs to carefully review the pathology again with your doctor if any doubt exists. Be sure to review all the information including your full story and present for scalp examination in order to have proper second opinion. Yes, Goserelin and hormonal changes from menopause can cause hair loss. It’s also possible that another issue that has not been raised in this submission is also responsible. In summary, it’s possible that the case represents LPP but it’s also possible it is not. Insufficient information has been presented in this submission to render any kind of definite conclusion.
