Pachydermoperiostosis (PDP), also known as Touraine-Solente-Gole syndrome or primary hypertrophic osteoarthropathy, is a very rare disease mainly characterized by pachyderma, finger clubbing, hyperhidrosis, and periostosis. We reported a case of a patient who suffered from gradual pain and enlargement of both hands and feet for 25 years despite receiving treatment from multiple clinics. He also experienced gradual abnormal changes in his face and scalp. Radiographic images of the lower limbs revealed the presence of subperiosteal bone growth and periosteal hypertrophy. The diagnosis of complete PDP was made late due to its rarity and the unfamiliarity of medical practitioners with the diagnosis. This case highlighted the need for medical practitioners to be aware of rare diseases so that patients may be diagnosed and treated earlier and thereby relieving their anxiety and improve their quality of life.
