JAAD Grand Rounds Quiz on Dermatological Conditions

The document described a JAAD Grand Rounds quiz focusing on dermatological conditions, including woolly hair nevus and focal alopecia. Woolly hair nevus was characterized by tightly coiled, lusterless hair patches that appear at birth or early childhood, often associated with epidermal nevi and sometimes eye abnormalities. The condition was diagnosed clinically and had no effective treatments. A case of a 65-year-old woman with focal alopecia was also discussed, highlighting a slowly enlarging plaque on the scalp, diagnosed as alopecia neoplastica, likely due to metastatic spread from a previous breast carcinoma. The document provided diagnostic questions and answers for educational purposes.
