Mammary Paget's disease occurs on the nipple-areola complex and may spread to surrounding skin. It was initially described in 1874 by Sir James Paget [1]. The typical clinical presentation includes itching, erythema, scale, erosion, and nipple drainage [2]. We present an elderly woman patient with melanoma of the nipple that had the gross appearance of Paget's disease.


Clinical synopsis

An 86-year-old woman presented with persistent, erythematous, ulcerative changes of her left nipple for several months. Physical examination showed a scaly, erythematous, crusty, and thickened plaque with some hyperpigmentation on the nipple. Erythema and scale extended onto the surrounding areolar area (Fig. 1). Bleeding from the nipple occurred off and on for two months. Paget's disease was the initial clinical impression. Chest X-ray, bone scan and liver ultrasonography showed no evidence of metastasis. The patient underwent wide excision. The pathology confirmed nodular melanoma (Figs. 2 and 3). No recurrence was observed during a 6-month follow-up.

Discussion

Melanoma of the nipple is quite uncommon; most of the cases are metastatic [3]. Furthermore, this tumor is relatively uncommon in Asian patients. Paget's disease of the nipple would be more common in Asian populations and may be hyperpigmented. Therefore the correct diagnosis requires histological interpretation [4]. Although rare, melanoma of the nipple may mimic Paget's disease.
