A 28-year-old female presented with an area of thickening and hypopigmentation of the skin over the left side of her neck for 2 years [Figure 1]. She gave history of reddish discoloration of the skin initially which slowly started thickening and became hypopigmented. She had applied several topical medications for the same. On examination, there was an oval hypopigmented indurated plaque over the left side of the neck with the surrounding skin showing hyperpigmentation.
Dermoscopic examination of the lesion was done (Dermlite DL3N, California USA, 10×). In the polarized mode, there were whitish fibrotic beams with linear branching vessels crossing the beams [Figure 2]a. It is important to differentiate the pattern of vessels in morphea from cases of steroid abuse where the vessels are mostly telengiectatic compared to linear branching vessels in morphea crossing the white fibrotic beams. In addition, the area showed loss of hair compared to the surrounding skin, again supporting the diagnosis of morphea [Figure 2]b. Histopathological examination of the biopsy was done for confirmation of the diagnosis, which showed thinned epidermis with flattened rete ridges, minimal inflammation in the dermis with collagenization of dermis, and loss of adnexae [Figure 3]a. The papillary dermis showed homogenous collagen whereas reticular dermis and subcutis consisted of thickened closely packed hypocellular eosinophilic collagen bands with hyalinization arranged parallel to each other. Mild perivascular chronic inflammation and absence of adnexae was seen in the dermis [Figure 3]b. The white fibrotic bands correspond to the dermal sclerosis seen on histopathology, and loss of adnexae was seen both on dermoscopy as well as on histopathology.

Morphea is a disorder of unknown etiology which presents with localized area of skin sclerosis. The dermoscopic examination of morphea can be beneficial in cases where the diagnosis is not clear, especially in darker skin types where the typical lilac border surrounding the plaque of morphea is difficult to appreciate. Whitish fibrotic beams seen on dermoscopic examination are very specific for morphea, which are frequently crossed by linear branching vessels. Furthermore, the loss of appendages is evident on the magnified examination of the lesions. Dermoscopy is helpful in differentiating between morphea and lichen sclerosus as comedo-like openings and white patches characteristic of lichen sclerosus are seen less commonly in morphea.,
