PATHOLOGY QUIZ CASE 1  LCDR Michael E. Moreland, MC, USNR, Naval Regional Medical Center, Portsmouth, VaAn 84-year-old woman came to our clinic with a foulsmelling lesion on her scalp. It had been growing slowly during a 15-year period, and, until recently, she had been able to hide it in her hair. There was no family history of a similar lesion. Examination disclosed a 4 × 6-cm, firm, mushroom-shaped, exophytic tumor of the sagittal part of the scalp (Fig 1). The lesion was not fixed to underlying structures.
