title: Jadassohn's sebaceous nevus.
abstract: A total of 29 case reports of sebaceous nevus were filed for the years 1970 to 1980 in the Department of Pathology of the National Medical Center of El Salvador. In 2 cases (6.8%), association with basal-cell carcinomas were found. In 1 case, there was also a solitary pilar leiomyoma. Sebaceous nevus was found more frequently in females than in males (2:1 ratio), and the average age was 23.8 years at the time of the consultation. All diagnosed sebaceous nevi were located on the head (48.2% on the scalp), and 82.7% of the patients were under 30 years of age. In connection with the analysis of these cases, a brief review of the clinical, histologic, and evolutionary facts of the sebaceous nevus was carried out.
