“…[111][112][113] This structure, which has been J AM ACAD DERMATOL described as ''the outlines of a volcanic crater as observed from a high point'', 111 or as ''white track'', 113 surrounds a central whitish or red-whitish, scar-like area, in which scales and dotted or linear vessels may be observed.

“…From 1955 to January 2005, we found 61 dermoscopy articles reporting a variety of different indications in the context of NPSD [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61]. Preferentially we did not include dermoscopy articles in which the differential diagnosis to pigmented skin tumors was discussed.…”

“…Dermoscopy can also be used for diagnosing pediculosis capitis and pubis, since the dermoscopic examination of affected hairs provides a sufficient magnification for identifying pediculus hominis and pthyrius pubis. Dermoscopic examination of lesions of psoriasis [7,8,9,10,11,12,13], porokeratosis [20], pityriasis rosea [8, 13, 21], lichen planus [8, 9, 22], and Darier disease [23] often reveals specific criteria that may be helpful in selected, clinically equivocal cases (fig. 4, 5).…”

Dermoscopy improves the diagnostic accuracy in the clinical evaluation of pigmented skin lesions, but it is also useful for the assessment of vascular structures that are not visible to the naked eye. As a consequence, dermoscopy has been employed more and more for the differential diagnosis of nonpigmented skin disorders, including tumors but also inflammatory and infectious diseases. This article provides a review of the dermoscopic features seen in various nonpigmented tumoral and nontumoral skin lesions as well as the dermoscopic criteria used for monitoring skin reactions to various treatments.

“…Lesions spare the axillary vaults, inguinal folds, perigenital region, palms, soles and mucous membranes. Dermoscopy reveals a "white track" structure with brown pigmentation on the inside of the track that can be seen at the edge of an individual lesion, corresponding to the cornoid lamella [1]. Centrally, a white area with red dots, globules, and lines is present that corresponds to capillary vessels; it is more easily observed through the atrophic epithelium.…”

Sir,Disseminated superficial Porokeratosis is a heterogeneous group of disorders characterized by a distinct clinical finding of keratotic ridge with central groove that corresponds to cornoid lamella in histology. Anetoderma is characterised by localised loss of elastic tisssue resulting in herniation of subcutaneous tissue. We describe a rare association of disseminated superficial porokeratosis and anetoderma, which was developed after an episode of acute pancreatitis.A 56yr old male patient, farmer by occupation, was presented with multiple asymptomatic hyperpigmented annular lesions over the trunk since 8 months and multiple discrete yellowish sac like protrusions over trunk since 6 months. He gives h/o acute pancreatitis 10 months back for which he was treated conservatively. On examination there were multiple discrete annular hyperpigmented plaques of varying sizes with hyperkeratotic grooved borders over anterior and posterior aspects of the trunk and both the upper limbs and neck (Fig. 1). Multiple discrete yellowish sac like protrusions of sizes varying from 5mm to 10mm were seen over both the flanks and posterior aspect of the trunk. Button hole sign was positive (Fig. 2).Routine blood investigations and biochemical investigations were within normal limits. HIV and HBS Ag was negative. Histopathology of keratotic plaques showed foci of epidermal invagination filled with keratin and parakeratotic coronoid lamella ,dermis showed a mild to moderate infiltrate of lymphocytes and evidence of pigment incontinence which was consistent with porokeratosis (Fig. 3). Histopathology of sac like protrusions showed decreased elastic fibres in the papillary and reticular dermis. Staining with verhoeff-van Gieson was consistent with anetoderma (Fig. 4). With the above clinical and histopathological findings the diagnosis of disseminated superficial porokeratosis and anetoderma was confirmed. For larger lesions were treated with topical 5-flurouracil was given and smaller lesions with topical Tretinoin 0.05% cream. Significant improvement was seen within 3 months.
