: Viral infections can be diagnosed and treated accordingly. Atypical presentation or sometimes presenting with other dermatological condition can be difficult for diagnosis. Dermoscopy provide rapid diagnostic aid for diagnosis.
To evaluate dermoscopic patterns in viral infections.

... Reviewing and comparing the available data, we observed a new dermoscopic pattern only partially described in literature. Dermoscopically, according to the existing literature [2][3][4], white polyglobular structures were the most common features (100%), followed by meliceric crusts (100%), and erythematous background (71%). ...
... In literature a total of 75 patients, irrespective of age and gender, with a clinical presentation suggestive of HZ were evaluated for dermoscopic features [2][3][4]. Erythematous background (increased vascularity) was the most common finding (100%), followed by round cloudy white polyglobular structures (grouped vesicles) 53%-80%, and central brown dots 50%-80% (Table 1). ...

Also, focally distributed hypopigmmented dots corresponding to perifollicular areas were found [8] -Linear or circular arrangement of streak-like pigmentations arranged in a "parallel manner" following the lines of Blaschko [25] Lichen planus pigmentosus Fine/coarse, gray-blue/brown dots over a brownish background [26] Lichen planus pigmentosus with Blaschkoid presentation Discrete bluish-gray dots, globules, blotches and rods against a brownish background [9] IV Vitiligo Well-demarcated dense/glowing white area with perifollicular depigmentation (stable vitiligo) or perifollicular pigmentation (active vitiligo) [27]. ...
Introduction:
Incontinentia pigmenti (IP) is a rare X-linked geno-dermatosis characterized by numerous findings. Skin biopsy and histopathological analysis are considered as minor criteria for the diagnosis of IP. We assume that dermoscopy can assist the earlier diagnosis of IP.
Objectives:
To gain experience in earlier diagnosis of IP by observing dermoscopic findings of cutaneous changes.
Methods:
We revised confirmed cases of IP and examined them using dermoscopy, comparing histopathological and dermoscopic results.
Results:
Stage I presented solitary and grouped vesicles in linear arrangement on erythematous skin. Early stage II presented star-shaped verrucous lesions on erythematous or pigmented skin. In well-developed lesions, dotted vessels surround keratotic part, some with thrombosed capillaries, resembling a viral wart. Stage III presented linear brown dots on the pigmented areas. Dermoscopic image was uniform in all the examined pigmented Blaschko linear changes. Stage IV presented numerous dotted vessels on the hypopigmented skin. Terminal hair was scarce or absent in all four stages. The surrounding normal skin had perifollicular depigmentations in stages III and IV.
Conclusions:
Dermoscopy of all four stages is very specific compared to the dermoscopy of inflammatory dermatoses and pigmentations. Stage III has very close clinical, histological and dermoscopic mimickers and needs to be carefully examined with obligatory genetic testing. Dermoscopy of the stage IV closely corresponds to histopathological findings and may be crucial as a quick tool in revealing potential IP gene carriers. Dermoscopy should be used in addition to clinical examination since the two methods are complementary.
... A review of published studies describing dermatoscopy of herpes zoster yielded 89 cases (Table I). [2][3][4][5][6] These cases were largely from the descriptive studies conducted in India (Table I). The most common dermatoscopic features described included an erythematous background (100%); central brown dots (100%); white lines and reticular networks (90%); cloudy white polyglobular structures (53%-80%); blue-gray globules (80%); white globules (20%-80%); orange-yellow or brown-red globules (10%-50%); gray, brown, or black dots (30%-50%); and grayish, amorphous areas (20%). ...

[2][3][4][5][6] The different patterns observed may correlate with the clinical course of the disease. 2 An erythematous border, cloudy white polyglobular structures, orange globules, and grayish structureless areas were the features appreciated in our patient. The erythematous border corresponds to dilated blood vessels. 2 White globules represent spongiosis within the epidermis. ...
