| Fig. 20.8 Moth-eaten alopecia. |
The hair loss primarily affects the scalp but may also involve the eyebrows and eyelashes. It presents as a nonscarring, patchy alopecia that is described as a “moth-eaten” pattern (see Figure 20-8). This classic pattern appears to be uncommon in the 20th century. The most common pattern of hair loss in secondary syphilis today is a nonspecific diffuse hair loss due to a telogen effluvium (see Chapter 20).
