A 24-year-old male patient presented to us with raised skin lesions around his eyes, more over the right eye, since three weeks. The lesions were asymptomatic. The patient had been using lubricating eye drops for complaints of burning and foreign body sensation of the eyes which was diagnosed as dry eye disease by the ophthalmologist. There were no skin lesions elsewhere and the patient was otherwise healthy, no present or previous history of skin or systemic illness.
On examination, the lesions appeared as hyperpigmented, slightly verrucous, polygonal papules grouped together [Figure 1]. The lesions were located on the periocular area, more on the lower side. A clinical possibility of dermatitis neglecta was considered and on taking a more detailed history, the patient admitted to not cleansing the area properly because of the eye symptoms. On gentle swabbing with saline itself the scales came off easily [Figure 2], thus confirming the diagnosis of dermatitis neglecta. Dermoscopy (polarized light ×10, Dermlite pro hr ii) – mainly showed polygonal plate like brown scales arranged in a mosaic-like pattern, with a few smaller cornflake-like scales mainly on the peripheral part of the affected areas. Some of the larger scales had a bluish color. The lesion also showed a background erythema [Figure 3].

Errichetti and Stinco have reported that dermatitis neglecta (DN) and terra firmaformedermatosis (TFFD) tend to have distinctive dermoscopicpatterns, which can help to differentiate from each other and other conditions like pityriasis versicolor, macular amyloidosis, and frictional melanosis. The larger polygonal scales are more suggestive of TFFD, while DN is characterized by more irregularly distributed corn-flake like scales. The difference is explained by the histopathology, where TFFD shows more prominent papillomatosis, acanthosis, and compactorthohyperkeratosis, while DN shows basket-weave hyperkeratosis and diminished rete pegs.
The history of absence of cleansing and the easy removal by swabbing in our case suggested that DN was more likely than TFFD, but the dermoscopy features were a combination of those described in TFFD and DN. We would like to conclude that the dermoscopy features of TFFD and DN might also show some amount of overlap. This could be explained by the fact that both these conditions might show histological overlap too. Larger case series would probably help clarifying dermoscopic similarities and differences between the two conditions.
