Inflammatory linear verrucous epidermal naevus (ILVEN) is a rare form of epidermal naevus. It occurs as a linear dermatitic or psoriasiform plaque, with onset usually in the first 5 years of life. Lesions are characteristically intensely itchy. We present a case of ILVEN occurring on the vulva and perianal region of a 6-year-old girl. The lesion was initially thought to be an area of lichenified dermatitis; however, treatment with even super-potent topical corticosteroids did not significantly improve the inflammation. A biopsy was performed and histopathological examination showed characteristic features. ILVEN is frequently refractory to topical treatment and surgical excision of lesions may be an option for relief of symptoms. ILVEN occasionally presents in the inguinogenital region and in this area may, like many vulval naevi, be misdiagnosed as vulvitis, psoriasis, genital warts or sexual abuse.

Development of nevus spilus-like lentigines in zones previously affected by plaques of psoriasis has been described. Most cases have appeared following phototherapy; then it has been suggested that the mechanism involved could be an abnormal reaction to UV light. However, cases of multiple lentigines arising within resolving psoriatic in patients who had not received phototherapy or photochemotherapy have been described as a result of possible post-inflammatory hyperpigmentation. We report the case of patient who developed nevus spilus-like lentigines following therapy with topical calcipotriol on psoriatic plaques. We consider that the mechanism of production of lentigines is an unusual form of postinflammatory hyperpigmentation.

Dermal melanocytosis is a benign phenomenon most commonly noted in people with darkly pigmented skin. Multiple entities with dermal melanocytosis are described, including Mongolian spot, nevus of Ota, nevus of Ito, nevus of Hori, and acquired dermal melanocytosis. We report a case of acquired dermal melanocytosis occurring in a 42-year-old Hispanic man with psoriasis treated with infliximab for 9 months. The patient presented with an isolated pigmented patch on his left dorsal hand. Histopathologic examination of the skin revealed numerous dendritic, heavily pigmented melanocytes in the papillary and upper reticular dermis. We review the literature and discuss the pathogenesis of acquired dermal melanocytosis.

Red nail is a common disorder. However, a thorough examination of the patient's nails allows one to distinguish different diseases. For example, longitudinal erythronychia may be monodactylous or polydactylous. Only the former type can show histologically Bowen's disease or an amelanotic melanoma. Among the polydactylous type, the nosologic position of the acantholytic and dyskeratotic naevus versus Darier's disease is still controversial. Acantholytic epidermolysis bullosa looks like bullous Darier's disease, and acrokeratosis of Hopf may present also red longitudinal streaks. Subungual warty dyskeratoma is rare, but other dermatoses such as lichen planus, psoriasis, mail melanoma and various tumours have to be ruled out. Finally nail involvement in amyloidosis may precede the other signs of this systemic disease. The purpose of this paper will be focused on red nails that can present principally with red lunulae, solitary longitudinal erythronychia and multiple longitudinal erythronychia. Other aspects of this feature will also be raised.

The literature review for 2009 covers the principal themes of the speciality and brings new findings in the fields of pathophysiology, clinical features, therapeutical approaches. With regards to atopic dermatitis, we noticed new studies on potential inducing factors (breastfeeding, probiotics, food, vitamins, prematurity, Staphylococcus aureus and constipation). There are also new data on therapy using tacrolimus. With regards to vascular anomalies and especially haemangiomas, the literature comprises new data on evolution and efficacy of propranolol. With regards to congenital nevi, there are studies related to treatment and complications. With regards to warts, the literature brings news about virus transmission and therapy. With regards to genodermatosis (neurofibromatosis type I, cutis laxa, pseudoxanthoma elasticum, epidermolysis bullosa, ichtyoses and pilar diseases), we found novel facts in the fields of molecular analysis, clinical aspects, pathophysiology and quality of life. The literature in 2009 also contains studies on Lyell syndrome, Kawasaki disease, vitiligo, psoriasis, pityriasis rubra pilaris, urticaria and alopecia areata.

A total of 33 skin biopsies were sent to Bangladesh institute of health Science (BIHS) hospital at Mirpur, Dhaka by Consultant skin for histopathological diagnosis between a period of one year and three months. Out of these 33 skin biopsies histopathological diagnosis of psoriasis was made for 13(39.39%), chronic non specific dermatitis (eczema) in 4(12.12%), lichenoid lesion 4(12.12%). Ashy dermatosis 3(9.09%), Nevus 2(6.06%) and corn, hemangioma, prurigo simplex, pityriasis rubra pilaris (PRP), dermatofibroma, 1(3.03%) each. The main presenting feature of these patients were erythematous, prurituc, silvery, scale, plaques or papules for a period between 2 months to 15 years. It is evident from the present study that among different skin lesions sent for histological diagnosis, Psoriasis is common skin pathology in dermatological practice.

Nail disorders in children can be divided into seven categories. The first is physiologic alterations, which every physician should be aware of in order to reassure parents. These usually disappear with age and do not require any treatment. Among congenital and inherited conditions, the nail-patella syndrome, with its pathognomonic triangular lunula, should not be missed as recognition of the disease allows early diagnosis of associated pathologies. The most common infection is the periungual wart, whose treatment is delicate. Herpetic whitlow should be distinguished from bacterial whitlow as their therapeutic approaches differ. Dermatologic diseases encompass eczema, psoriasis, lichen planus, lichen striatus, trachyonychia, and parakeratosis pustulosa. Lichen planus, when it presents as in adults, is important to recognize because, if not treated, it may lead to permanent nail loss. Systemic or iatrogenic nail alterations may be severe but are usually not the first clue to the diagnosis. Beau lines on several fingernails are very common in children after temperature crest. Tumors are rare in children. Radiographic examination allows confirmation of the diagnosis of subungual exostosis. Other cases should undergo biopsy. Single-digit longitudinal melanonychia in children is mostly due to nevi. Its management should be tailored on a case-by-case basis. Acute trauma should never be underestimated in children and hand surgeons should be involved if necessary. Onychophagia and onychotillomania are responsible for chronic trauma.

Multiphoton tomography (MPT) is an in vivo imaging technique with very high spatial resolution and efforts are made to combine MPT with other non-invasive imaging methods. The goals of the present study were the description of the features of different dermatological entities as seen in MPT and confocal laser scanning microscopy (CLSM) comparison of these two novel techniques and the 'classical' diagnostic measures visual inspection, dermoscopy and histology with respect to the strengths and weaknesses of the different methods and the potential benefit from their combined implementation. After study approval by the local Ethics Committee, 47 patients (31 male, 16 female, age range: 24-88 years) were recruited from the Department of Dermatology of the University Hospital Jena. In this work, we present an illustrative selection of eleven cases from a clinical study combining in vivo MPT with in vivo CLSM. The patients presented with a broad range of dermatological disorders including seborrheic keratoses, angioma, actinic keratoses, melanocytic nevi, malignant melanoma, psoriasis, pemphigus vulgaris and scarring. Both methods, CLSM and MPT, were found to be suitable for in vivo imaging of superficial skin layers and may therefore be useful in dermatological practice for the diagnosis of skin diseases. However, both methods differ in their technical and physical principles. Thus, despite of many similarities concerning the morphological presentation of cells and tissues, important differences are recognized. Synergies of the combination of CLSM and MPT may be obtained by combined implementation in order to benefit from the fast overview given by CLSM and the detailed imaging of skin structures by MPT.

The true existence of naevoid psoriasis and inflammatory linear verrucous naevus as distinct entities has been a debatable issue. Each has been opined to be a variant of the other. Considerable clinical and histological resemblance is seen between the two conditions. We describe three cases which attempt to throw more light on this issue.
