Alopecia neoplastica usually presents as a nodule, plaque, patch, or ulceration on the scalp.[2]
Causes
Alopecia neoplastica can come from tumors that are malignant or benign.[3] The most common cancer linked to alopecia neoplastica was found to be GI cancer, followed by breast cancer.[2]
Epidemiology
According to one study, 53.7% of patients with alopecia neoplastica were women, compared to 46.3% of men. 59 was the median age at onset.[2]
