“…These vascular structures correspond to elongated, dilated capillaries in the dermal papilla and seem to correlate with disease activity [15][16][17]. Kim et al [18] used the term "glomerular vessels" for these dilated capillaries. In addition, Kibar et al [19] called a new term "signet ring vessels"; however, we followed the same terminology as in Ross et al's [15] report, calling the same structures "polymorphous beaded circles."…”

“…Biopsy may be needed; even so, there are times when histopathological investigation can be inadequate for diagnosis. Dermoscopic examinations of psoriasis and seborrheic dermatitis lesions yielded different morphologies especially in the microvascular structures so it can be useful in differentiating these diseases [10][11][12][13][14][15][16][17][18][19]. In this study we investigated the usefulness of dermoscopy in the clinical differentiation of psoriasis and seborrheic dermatitis on the scalp and as distinct from previous studies, we also evaluated correlation of dermoscopic findings with disease severity.…”

Dermoscopy has frequently been used for hair and scalp disorders. Dermoscopic examinations of psoriasis and seborrheic dermatitis lesions yielded different morphologies. This study aimed to investigate the usefulness of dermoscopy in the clinical differentiation of psoriasis and seborrheic dermatitis on the scalp and additionally to evaluate its capacity in determining disease severity. The study included 46 psoriasis and 50 seborrheic dermatitis patients who were clinically diagnosed and had scalp lesions. Dermoscopic images taken from lesional scalp were then reviewed for microvascular patterns. In addition, we assessed the severity of scalp disease and looked for a correlation with these patterns. The frequency of twisted loops, glomerular vessels, red dots/globules, and polymorphous beaded lines/circles were statistically higher in the psoriasis group, whereas the frequencies of simple loops and arborizing vessels were statistically higher in the seborrheic dermatitis group (p<0.001). There was no significant difference in the frequency of featureless areas between two groups (p=0.579). There was no correlation with disease severity and dermoscopic findings. In conclusion, dermoscopy is a valuable and easy-to-use tool for differentiating psoriasis and seborrheic dermatitis on the scalp even if it doesn't have enough strength to determine disease severity. In addition, there is some diversity and ambiguity concerning terminology, which can be resolved with future studies and the establishment of conventional terms.

Trikoskopi (saç ve saçlı deri dermoskopisi) klinikte sık görülen saç hastalıklarının ayırıcı tanısında kullanılan değerli bir in vivo tanı yöntemidir. Yöntemde tanı, foliküler açıklıklar, kıl gövdeleri ve perifoliküler epidermis olmak üzere dermoskopla görülebilen temel yapıların değerlendirilmesine dayalıdır. Bu yöntem klinikte, erken androgenetik alopesi tanısında, androgenetik alopesi ve telojen efluvium ayırımında, yamasal alopesilerin ayırıcı tanısında ve skarlı alopesilerin skarsız alopesilerden ayrımında fayda sağlar. Bu makale, trikoskopide gözlenen temel yapısal özelliklere ait anormalliklerle ilgili şuanki bilgilerimizi ve sık görülen saç hastalıklarının karakteristik görünümlerini özetlemektedir.

Özlem Dicle Trikoskopi Trichoscopy Özet AbstractTrichoscopy (hair and scalp dermoscopy) is a valuable in vivo tool for the differential diagnosis of clinically frequent hair diseases. It is based on evaluation of basic structures that may be visualized with a dermascope; follicular openings, hair shafts and perifollicular epidermis. This method is useful to diagnose early androgenetic alopecia, to distinguish androgenetic alopecia from telogen effluvium, to make differential diagnosis of patchy alopecias and differentiate scarring from nonscarring alopecias. This article summarizes the current knowledge in abnormal appearances of basic structural components on trichoscopy and characteristic trichoscopic features of the most common hair diseases.

“…In the literature, it was stated that dermoscopic pattern of psoriasis consisted of uniformly distributed, dotted vessels on a light red background and red globules, twisted hairpin and glomerular vessels could also be seen under dermoscopy. 3,4 However, the dermoscopic pattern of PRP consisted of round/oval yellowish areas surrounded by vessels of mixed morphology. 5 The dermoscopic findings of erythematous plaques of the patient presented herein is consisted with the PRP findings of the latter study.…”

ighteen-year-old female patient with with red scaly plaques on her forearms, legs and scalp, was referred to our out-patient clinic (Figure 1). The disease duration was over 10 years. The female patient was previously diagnosed as psoriasis. She was treated with various topical anti-psoriatic agents unsuccessfully. The lesions were not completely cleared. The patient was evaluated and clinical differential diagnosis included a number of erythematosquamous skin diseases. Due to the shape and arrangement of lesions , the diagnosis of seborrheic dermatitis, pityriasis rosea, lichen planus, pityriasis lichenoides et varioliformis acuta, pityriasis lichenoides chronica and parapsoriasis were excluded. And preliminary diagnosis of pityriasis rubra pilaris (PRP) and psoriasis were concluded. Skin punch biopsy was performed from her left forearm. Histopathological examination showed parakeratosis, loss of granular layer limited to small foci with diffuse hypergranulosis, and perivascular lymphocyte, histiocytes and extravasated erythrocytes in upper dermis (Haematoxylin-Eosin, original magnification x100) (Figure 2). These histopathological features were not fully consistent with psoriasis and did not exclude the diagnosis of PRP. Later, we performed dermoscopic examination on erythematous plaques and it revealed round/ oval yellowish areas surrounded by vessels of mixed linear and dotted morphology (Figure 3). These findings were consistent with dermoTurkiye Klinikleri J Dermatol 2016;26 (1) 69
