Pott's Puffy Tumor in an Adult

Abstract

Pott's puffy tumor(PPT)was first reported by Percival Pott in 1768, and is a rare disease that is characterized by the formation of a soft subperiosteal abscess on the forehead due to frontal osteomyelitis. A 46-year-old man with no history of frontal surgery, trauma, or underlying disease visited our hospital with the complaints of fever and swelling of the forehead. Imaging showed an osteolytic lesion of the frontal bone caused by osteomyelitis, with a contiguous subperiosteal abscess of the forehead, and soft tissue shadows in the right frontal sinus and other paranasal sinuses. The subperiosteal abscess was drained by external incision, and the sinuses were opened and washed endoscopically. After the operation, the infected lesion was washed and antibiotics were administered. At 10 months after treatment completion, no recurrence was observed and bone regeneration of the osteolytic lesion was confirmed.With the widespread use of antibiotics in recent years, the number of reported cases of PPT has decreased, and although it is fairly rare, it is important for otorhinolaryngologists to be well aware of this disease, as it can sometimes become fatal because of secondary intracranial infection.
