TLDR Treatment with benzylpenicillin and prednisolone cured the patient's syphilis and hair loss.
A patient presented with large ulceration on the hard palatine mucosa and cervical lymphadenopathy, and was diagnosed with secondary syphilis with alopecia syphilitica diffusa, lymphadenopathy, and a persisting hard chancre. Laboratory tests confirmed the diagnosis with a reactive TPPA and a VDRL test of 1:256. Treatment with a single intramuscular injection of benzylpenicillin and prednisolone prophylaxis led to complete resolution of symptoms. Alopecia syphilitica, a rare manifestation of secondary syphilis affecting about 5% of patients, can mimic alopecia areata and is characterized by non-inflammatory, non-scarring hair loss in a diffuse or moth-eaten pattern.
