For more numerous or widespread lesions, or if the patient shows no response or is intolerant to the options above, the following are first-line oral therapeutic options: Follicular mucinosis is a xlopecia reaction pattern wherein variable amounts of epidermally derived mucin accumulate within follicular infundibula and the outer root sheath epithelium.
With the good response to MDT in the previous 2 cases it was decided to start him also on MDT, however, as he was shortly returning to the USA, he was started on ROM therapy rifampicin mg, ofloxacin mg, minocycline mg to be taken once a month for 6 months.
