Dermoscopy is a non invasive diagnostic method. Dermoscopedia is the online resource for dermoscopy and is provided by the international dermoscopy society. This is the glossary page of term pseudo-network Pseudonetwork of the face. This type of pigment network is due to the particular anatomy of the facial skin that is devoid of rete ridges and is characterized by closely situated follicular infundibula. Thus, a diffuse pigmentation of the epidermis or the papillary dermis in facial skin reveals a peculiar pigment network, also called. The term 'pseudonetwork' is used when annular pigmentation is seen around hair follicles on facial skin. At times on the face, it may be difficult to differentiate benign naevi, lentigo, actinic keratoses, lichenoid keratosis and early lentigo maligna. Pseudonetwork: facial ski The pseudonetwork in benign lesions is symmetrical and regular. Some solar lentigines do not have pseudonetwork and are uniformly amorphous; the flat seborrhoeic keratosis with dry or scaly surface may reveal white reflected or dull yellow keratin.

Lichenoid keratosis is a skin condition that typically occurs as a single papule or thickened area. We'll show you what it looks like, and explain what causes it and how it's treated In some instances a classic pseudonetwork and a delicate pigment network inherent to solar lentigo may be found closely associated. More frequently, a homogeneous pattern is combined with a delicate, light brown, typical pseudonetwork. In other instances so-called moth-eaten edge is recognizable as a non-uniform concave area resembling a. .0.0.0. A router that is generating the default for a network also might need a default of its own. One way a router can generate its own default is to specify a static route to the network 0.0.0.0 through the appropriate device. When default information is passed through a dynamic routing protocol, no.
Pseudonetwork. Pseudonetwork and annular granular structures were the most frequent dermoscopic patterns among pigmented lesions of the face, irrespective of their benign or malignant nature 15.

Next Steps in Derm is a virtual mentor for dermatology residents and young physicians seeking dermatology updates, advice on practice management and building their careers Many operating systems have long had pseudo-teletypes, inter-process communication channels that provide terminal semantics on one end, and a smart server program on the other. We describe an analogous concept, pseudo-network drivers. One end of the driver appears to be a real network device, with the appropriate interface and semantics; data written to it goes to a program, however, rather.

Although dermatoscope is a powerful tool to examine pigmented skin lesions, its magical technical terms sometimes derange the diagnosis. Network and pseudonetwork patterns with irregular structures are common in SK. However, we were confused with the regression structure with blue-gray dots Pseudonetwork: facial skin • Term 'pseudonetwork' is used when annular pigmentation is seen around hair follicles on facial skin. • On face, it may be difficult to differentiate benign naevi, lentigo, solar keratoses, lichenoid keratosis and early lentigo maligna. Solar lentigo Solar lentigo Solar keratosis Lichenoid keratosis 22 A partial gray pseudonetwork and annular granular structures were also noted (Figure 1A). A partial biopsy confirmed the diagnosis of LPLK. After three months, the pinkish area remained, with decreased brown color and gray pseudonetwork as the main features (Figure 1B)
Of a total of six cases, three main dermoscopic structures were found: pseudonetwork, structureless areas, and cobblestone pattern. Our preliminary findings suggest that dermoscopy may be helpful in improving the diagnostic accuracy of Spitz nevus of the ear and minimize surgery in a sensitive location Lentigo maligna is melanoma in situ, a precancerous lesion that may progress to an invasive melanoma (specifically lentigo maligna melanoma subtype).This condition typically occurs in sun-damaged areas (e.g., face and neck) of elderly patients. Lentigo maligna presents as a brown macule with color variegation and asymmetrical borders that grow slowly The critical matrix ligament thickness for the blends with the pseudonetwork morphology is 0.11 μm, which is much larger than that (0.059 μm) for the blends with the morphology of well-dispersed rubber particles. Therefore, pseudonetwork morphology is much more effective in toughening PVC than the morphology of well-dispersed rubber particles
.9,11 It is important to emphasize that the pseudonetwork pattern occurs likewise in melanocytic and nonmelanocytic lesions.11,12 Accordingly,thediagnosisofagivenpigmented facial macule relies on the detection of additional specific criteria. The specific dermatoscopic criteria of melanocyti Per dermatoscopic analyses, a red pseudonetwork was substantially associated with AK compared with other diagnoses (P =.02), but cSCC was characterized by keratin and linear-irregular vessels (P <.001). Skin scaling (P =.04) and glomerular vessels (P <.001) were more common in IEC compared with other lesion types
The most striking pattern in 39 of Apart from the erythema/red pseudonetwork structures, we 41 (95%) facial AKs was a 'background' erythema that was found fine, focused linear 'wavy' vessels surrounding the hair follicles in more than 80% of facial AKs (Fig. 1A) LM presents an atypical pseudonetwork characterized by different patterns, depending on the age of the lesion. These include, in chronological order, an annular‑granular pattern due to the aggregation of blue‑grey globules around follicular ostia; a greyish pseudonetwork secondary to thickening of th Instead, a pseudonetwork with a broad mesh and holes is created by the numerous pigment-free terminal and vellus hair follicles, as well as the openings of sweat glands. This pseudonetwork is location dependent and therefore present in both melanocytic lesions and nonmelanocytic lesions, such as seborrheic keratoses, on the face
A pseudonetwork pattern refers to the common dermoscopic finding of melanocytic and non-melanocytic pigmented macules of the face; it is a structureless diffuse brown pigmentation interrupted by numerous, variably broad, and hypopigmented holes, which correspond to hair follicles and sweat gland openings. Based on a report by Schiffner et al. Pigmented tumors have similar clinical features that overlap and hamper diagnosis. Dermoscopy increases the diagnostic accuracy of doubtful melanocytic lesions and has been used as a noninvasive tool in the detection of pigmented lesions (PLs) like melanoma, basal cell carcinoma, and pigmented Bowen's disease (pBD). Our objective was to show the dermoscopic features of 2 cases of pBD and.
The pseudonetwork is due to homogeneous pigmentation that is interrupted by the non-pigmented follicular openings 5. In this study, we also confirmed grey dots/granules and pseudonetwork in all cases the same as in the previous study 3. However, the dermoscopic features of Riehl's melanosis in the neck showed different patterns compared with. pseudonetwork is due to homogeneous pigmentation that is interrupted by the non-pigmented follicular openings5.

So-called pseudonetwork is commonly seen in solar lentigo (see figure 7 right) and pigmented actinic keratosis, neither of which are melanocytic. Lines radial segmental are seen in pigmented basal cell carcinoma (BCC) (see figure 17 lower images) and i This pseudonetwork is observed in melanocytic and nonmelanocytic pigmented lesions on the face. Diagnosis thus is based on the detection of additional criteria, and while the pseudonetwork is specific to the face, it does not offer any information on the lesion's histologic subtype . 1, deﬁned red pseudonetwork and surface scales. When using polarized dermoscopy, it is possible, at times, to visualize the so called rosettes, they are deﬁned as four closely aggregated white, small dots in correspondence to follicular opening resembling 4-leaf clover.

L2TPv3 - Layer 2 Tunneling Protocol Version 3 is an IETF standard related to L2TP that can be used as an alternative protocol to Multiprotocol Label Switching (MPLS) for encapsulation of multiprotocol Layer 2 communications traffic over IP networks. Like L2TP, L2TPv3 provides a 'pseudo-wire' service, but scaled to fit carrier requirements Facial pigmentary disorder is a common condition in dark-skinned individual which causes significant psychological morbidity to the patients. Some of the well-defined causes of facial melanoses include melasma, Riehl's melanosis, lichen planus pigmentosus, erythema dyschromicum perstans, and poikiloderma of Civatte The highest prevalence among the variants of LP was of classical form (29%) and lowest was of inverse LP (0.6%). Overall, the mean age of the patients was 36 years, with a standard deviation of 17. There was one instance of LP occurring in both father and son. Conclusion: The most common age group of LP was 18 -40 years
Lichenoid keratosis forms because of a buildup of excess dead keratin cells. Keratin is a protein that is found in your body that makes up most of your nails, hair, and skin. It can also be found in tooth enamel. As our body pushes this protein to the surface of your skin it dies. When the dead keratin cells build up it can lead to a scaly or.

PseudoTV Live can directly integrate with various Kodi plugins and video sources such as Playon, Hdhomerun and PVR backends. - PseudoTV/PseudoTV_Liv Gallery. Dermoscopy reveals a hidden world of morphological structures in skin lesions. The following examples illustrate some of the features seen. Benign naevus showing pigmented network (Fig 1) Benign naevus showing cobblestone pattern (Fig 2) Benign seborrhoeic keratosis (Fig 3) Benign dermatofibroma showing the characteristic pseudonetwork. Description: Pattern shows very coarse lines reticular, pink structureless area top right, and grey in a pattern not unlike annular/granular in facial lesions. It has been suggested that heavy actinic damage may efface the rete ridges, giving rise to pseudonetwork, not network. I could not dermoscopically diffentiate between regressing solar lentigo and lentigo maligna The papule was abutting a hair follicle. Of note, there was background sun-damaged skin characterised by erythema, pink-red pseudonetwork (annular pigmentation that resembles a network, surrounding white areas corresponding to follicular openings), unfocused blood vessels and white halo structures around yellow (keratin-filled) follicular.
Fertsch M., 2020. Artificial neural pseudo-network for production control purposes. LogForum 16 (1), 7-13. Dermoscopy (also called dermatoscopy, epiluminescent microscopy, or episcopy) is a noninvasive method of examining skin lesions using a hand-held magnifying device (a dermoscope) equipped with a light source. 1 Dermoscopy allows adequate visualization of the structures in the skin not only by magnifying them but also by eliminating the surface light reflection and scatter that obscures the. If a router has an interface that is directly connected to the specified default network, the dynamic routing protocols running on the router generates or sources a default route. In the case of RIP, the router will advertise the pseudonetwork 0.0.0.0. In the case of IGRP, the network itself is advertised and flagged as an exterior route Result. strawberry pattern (erythematous background, pink-to-red pseudonetwork, thin undulated vessels surrounding hair follicles, white-to-yellow scale, hair follicles filled with yellowish keratotic plugs, surrounded by a white halo)
In benign lesions, this pseudonetwork tends to be uniform and symmetric in color and pattern. In contrast, in lentigo maligna and lentigo maligna melanoma, the pseudonetwork becomes nonuniform and asymmetric in color and pattern because of the increased number of atypical melanocytes extending down hair follicles and adnexal structures There may not be a more vapid politician in America than Georgia Sen.

Analysis 3: Individual Node Properties Keratoacanthoma (KA) is a relatively common, benign, epithelial tumor that was previously considered to be a variant of squamous cell carcinoma (SCC). The etiology is unknown. No human papillomavirus -DNA sequences were detected in lesions by polymerase chain reaction. It is a disease of the elderly (mean age, 64 years) with an annual incidence.
Thus the link ((i, j), (j, It)) in the pseudonetwork corresponds to the hook (i,'j, k) in the network. Let the link values in the pseudonetwork be the corresponding hook values in the network.

Additional dermatoscopic features include a perifollicular whitish. Indeed, retrospective review of 243 patients who underwent dermoscopy showed that the red pseudonetwork of vessels was significantly associated with AK, while hairpin and linear-irregular vessels were significantly associated with invasive SCC and keratoacanthomas
