Jadassohn's sebaceous nevus.

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.

[Malignant melanoma in El Salvador. Study of 101 cases].

We studied 101 Malignant Melanomas (MM) in the files of Department of Pathology of the National Medical Center of El Salvador. The incidence was 0,20 per 100.000, 54.5% in females and 45.5% in males. The mean age was 53.9% years (range 16 days-115 years). Highest frequency there occurred among 41 and 50 years. 42.5% were placed in lower limbs, 17.8% in the face, 14.8% in thorax, 7.9% in upper limbs, and 4.95 in the eye. In 18.8% it was found the antecedent of "mole" previous in the site of the tumor. 43% of the patients consulted before 6 months of evolution. In 53.8% metastasis were detected at the time of consultation. Microscopically 98.1% were of the nodular type and 1.9% lentigo maligna melanoma. Amont the nodulars, 38.5% were predominantly to epitheloid cells, 8% to fusiform cells, and 53.5% to mixed cells. 63% were placed at Clark's level V, 32% at level IV, and 5% at level III. All of them were more than 1.5 mm. in depth. 52% were medium thickness and 48% were more thant 4 mm. It is worth to emphasize: the highest frequency among females, the highest incidence in lower limbs and the microscopic aggressiveness of these tumors, almost all being of nodular type.
