Alopecia neoplastica as a sign of visceral malignancies: a systematic review

Abstract

Alopecia neoplastica (AN) from visceral tumors is a rare form of cutaneous metastasis in which internal malignancies spread to the scalp. The diagnosis of AN may be very challenging, especially when its onset precedes the diagnosis of the primary tumor.

We aimed to improve the knowledge on AN, highlighting that in case of scarring localized alopecia, a differential diagnosis with metastasis should always be considered.

We performed a systematic review to describe the main demographic and clinical features associated with AN from visceral malignancies; a survival analysis was also performed.

In 118 reports, accounting for 123 patients, we found that women were more affected by AN than men (53.7% versus 46.3%). The most frequent site of the primary tumor was the gastro‐intestinal tract (24.4%), followed by breast (17.9%), kidney (8.1%), lung (7.3%), thyroid (7.3%), uterus (6.5%), central nervous system (6.5%), liver (3.3%) and other anatomic areas for 18.7% of cases. Furthermore, in more than half of cases (66.1%) AN lesions were single and were mainly diagnosed after the primary visceral tumor (71.5%). Finally, survival analysis highlighted a lower progression free survival in men; while, no significant differences in overall survival were reported among genders. In conclusion, metastatic skin disease should always be taken into consideration when dealing with patients with localized scarring alopecia.
