Abstract |
Background |
The scalp is a unique anatomic region, in which pilosebaceous follicles are concentrated.
Objective |
We sought to investigate demographic characteristics and histologic distributions of malignant scalp tumors.
Methods |
Primary and metastatic scalp malignancies diagnosed histopathologically between 1983 and 2003 were reviewed. Age at diagnosis, sex, and histologic types were analyzed.
Results |
A total of 398 Taiwanese patients (200 males, 198 females) were selected. Age at diagnosis ranged from 3 to 103 years. Most malignant scalp tumors (69.8%) occurred in those 50 years or older. Basal (41.2%) and squamous (16.6%) cell carcinomas were the most common histologic types. Surprisingly, metastatic tumors (12.8%) came in third, in which lung cancers were the most frequent primary tumor in both male and female patients.
Limitations |
In our series, the case number of metastatic scalp malignancies was underestimated because not all patients with metastatic scalp tumors received a scalp skin biopsy.
Conclusion |
Because a wide spectrum of primary and metastatic malignancies can occur on the scalp, scalp inspection should be included in general screening for either skin or internal cancers.
