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. The tissue at the base of the lesion was macerated and purulent. Results of the rest of the physical examination were unremarkable. Sections from a skin biopsy specimen are shown in Fig 2 through 4.What is your diagnosis?
