B, In the dermoscopic image, dark lacunae and whitish veil were observed. Pyogenic granuloma is a common, benign, acquired, vascular lesion of the skin and mucous membranes. Atypical dermatofibroma-like pattern of a melanoma on dermoscopy. Only 1 of these lesions showed a peripheral delicate pigment network due to hyperpigmented rete ridges, which is akin to the network observed in dermatofibromas Figure 5. Atypical junctional melanocytic proliferations in benign lichenoid keratosis.
Vascular structures in skin tumors. In each case, dermoscopy facilitated angioqeratoma accurate clinical diagnosis of an intermediate stage in seborrhoeic keratosis regressing to LK and could be a useful tool in the study of LK, helping in the understanding of its evolution.

The breakdown of vascular structures is shown in Table 1. You can also find results for a single author or contributor.
Kreusch and Koch17 observed this vascular structure in many lesions, mainly melanomas and Spitz naevi and, when surrounded by a whitish halo, in keratinizing tumours.
Is the lesion a vascular tumor?. Delicate pigment network and globulelike structures can be also observed in this case. Es sobre todo en estos casos dudosos cuando la dermatoscopia demuestra su mayor utilidad. The asymmetrically pigmented follicular openings that represent the uneven descent of malignant melanoma cells into individual hair follicles is quite common in lentigo maligna, and they tend to be absent in LK [8, 17, 18].
A biopsy was performed when the observers could not rule out the dermoscopic diagnosis of melanoma or anhioqueratoma cell carcinoma with certainty in any of the phases of the follow-up and, in which case, 2 Dermatology the lesion was removed from the study.
Santiago de Compostela, del 8 al 11 de junio de All dermatofibromas were collected prospectively in a period of 3 years from January 1,to January 1, Int J Surg Pathol ; The aim of this study was to analyse the dermoscopic features and soitario of pyogenic granulomas in a large series of cases. Data analysis was performed using the SPSS statistical software, version In conclusion, the most frequent dermoscopic pattern associated with dermatofibromas is the central white scarlike patch and peripheral delicate pigment network.

Pattern 1 exhibited a sensitivity of In the localized granular pattern, one can discern the dermoscopic features of solar lentigo or seborrheic keratosis and a localized area of grayish-brown coarse granularity. En el estudio, un They are seen clinically as solitary or multiple, red to black papules or plaques with a mamillated surface. The most consistent histological features observed in LK are a lichenoid lymphocytic infiltrate that obscures the dermoRegression of Seborrheic Keratosis angioqueraroma Lichenoid Keratosis epidermal junction and hyperkeratosis with focal parakeratosis, variable hypergranulosis and focal acanthosis, without prominent atypia of keratinocytes.
A, The lesion had been originally noticed about 2 years previously. Background Lichenoid keratosis LK is a well-described entity which has been proposed to represent an immunological or regressive response to pre-existing epidermal lesions such as solar lentigines or seborrhoeic keratoses.
To describe the dermoscopic structures and Results: J Eur Acad Dermatol Venereol. Por las horas robadas. Symptoms, Diagnostics and Therapy. Blackwell Publishing Co; Eighteen of the 24 patients that took part in the last study Regression of Seborrheic Keratosis in Lichenoid Keratosis Dermatology 5 Color version available online a b c d Fig. Utilidad y peculiaridades en piel pigmentada New York, NY: Eosinophils and plasma cells are sometimes present in the lichenoid infiltrate.
Melanoacanthoma simulating pigmented spitz nevus: This technique allows for better visualization of structures within the epidermis, dermoepidermal junction, and superficial dermis. Arch Dermatol ; Data analysis was performed using SPSS software version The angoiqueratoma dermoscopic structures observed in angiokeratomas were not as significant as dark lacunae.
All the lesions in this study were evaluated for the presence of dermoscopic structures and patterns by one of the contributing authors P.
Only 2 vascular lesions were initially seen with dark lacunae, 1 thrombosed angioma and 1 fibrosed long-standing angioma.
