Alopecia areata associated with regression of cutaneous melanoma.

| Abstract |
A 41-year-old white female with a past medical history of hypothyroidism and alopecia universalis presented on January 24, 2002 with a recently changing mole. She indicated changes in size and color of the superior aspect of a mole that had been present for more than 8 years. She had approximately 20 lifetime peeling sunburns due to being a lifeguard. No family or previous personal history of skin cancers, including melanoma or atypical nevi, was reported. Her history of alopecia universalis began 12 years previously and has partially resolved with remaining patchy alopecia of the scalp and eyebrows. On diagnosis of alopecia universalis, she was initially treated with oral prednisone for 1 year and topical minoxidil for 3 months. Currently, she is not being treated for this condition. She denied other previous skin conditions. She had a surgical history of tonsillectomy at the age of 7 years. Her current medication includes levothyroxine (0.015 microg) for hypothyroidism diagnosed 12 years previously. She reported no known drug allergies. During the initial physical examination, she presented with phototype II skin with two adjacent pigmented lesions on her left foot within a 1.3 cm square. The first lesion on the left posterior distal heel was an irregular, brown-black, 0.5 x 0.6 cm macule. The second lesion, on the left posterior proximal heel, was an irregular, brown, speckled, 0.3 x 0.4 cm macule (Fig. 1). The patient had ophiasis of the scalp and total alopecia of the bilateral eyebrows. In keeping with the patient's wishes, alopecia lesions were not biopsied and clinical photographs of the alopecia are not included in this article. Two 3 mm punch biopsies were performed within each lesion. The left posterior proximal lesion showed malignant melanoma, with a Breslow depth of 0.4 mm, anatomic level II, marked lymphocytic response and partial regression (Fig. 2). The left posterior distal lesion showed malignant melanoma in situ, arising in a lentiginous compound nevus, with architectural disorder and cytological atypia. These two lesions were concluded to be one lesion with clinical regression. She underwent local excision with 1-cm margins and sentinel lymph node biopsy owing to the presence of regression, which showed no evidence of metastatic melanoma. Lactate dehydrogenase and chest X-ray were within normal limits. The alopecia areas were not biopsied previously or at that time.
