A 45-years-old female presented with a longstanding itchy lesion on the left breast for last eight months. Patient complained of severe itching and burning sensation in the lesion. On examination, a well-defined, erythematous to hyperpigmented, indurated, scaly and crusted plaque was seen over the left nipple and surrounding areola [Figure 1]. No palpable mass was found on examination of the breasts, and no regional lymphadenopathy was noted. Dermoscopy of the central erythematous portion revealed whitish pink area with irregular dotted vessels and chrysalis like structures. Multiple dotted vessels surrounded by white halos and adherent fabric fibers in structureless dark red areas were seen [Figure 2] and [Figure 3]a, [Figure 3]b. A skin biopsy was obtained from the lesion and sent for histopathological examination which demonstrated features consistent with mammary Paget's disease [Figure 4]a and [Figure 4]b.

Paget's disease (PD) of the breast was first described by Sir James Paget in 1874 in 15 women with chronic eczematous disease on the skin of the nipple and the areola. It is a very rare entity and comprises 1-4% of all patients with breast cancer. The peak incidence of mammary Paget's disease is between 50 and 60 years, and it occurs almost exclusively in females, being extremely rare in males. It is now widely accepted that mammary Paget's disease is always associated with an underlying carcinoma of the breast even in the absence of lump or mammographic abnormality.
Dermoscopy of the lesion reveals irregular linear vessels and multiple blue grey dots (peppering) corresponding to melanophages in the papillary dermis. Shiny white streaks or chrysalis like structures were recently identified as dermoscopic features of mammary Paget's disease. They are oriented parallel or orthogonally to each other and represent new or remodelled collagen bundles. Chrysalis like structures have been described in other conditions like dermatofibroma, scars, basal cell carcinoma, pyogenic granuloma, spitz nevus and melanoma. The pigmented variant displays a non-specific pattern with diffuse irregular pigmentation and regression like structures. The pigmented variant on dermoscopy needs to be differentiated from melanoma. Dermoscopy can thus be a useful tool in the early diagnosis of mammary Paget's disease which may otherwise be missed, especially in the absence of any associated breast lump or lymphadenopathy.
