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.

  1. A 52-year-old woman consulted for a pigmented lesion of her nose. This lesion was biopsied and pathology revealed an actinic keratosis. The dermoscopic feature was a pseudonetwork. The dilated follicular openings seen on the facial skin create a f alse broadened network or pseudonetwork that can be observed in various benign pigmented lesions as ephelide (freckle), actinic lentigo, actinic.
  2. Pseudonetwork (Figure 6). The term pseudonetwork is used to define homogenous pigmentation interrupted by nonpigmented ostia of adnexal structures characteristically seen on the face. It is mainly found in nonmelanocytic pigmented lesions on the face such as a solar lentigo, but it can also be seen in melanocytic lesions as well
  3. Pseudonetwork pattern . The anatomy of the rete ridge pattern of the face differs from that of non-facial skin, and is usually flatter. Accordingly, the pigment network is usually absent in these locations and is replaced by a pseudonetwork pattern

  5. Lentigo maligna is a specific type of melanoma in situ that occurs around hair follicles on the sun-damaged skin of the head and neck. Lentigo maligna melanoma is diagnosed when the melanoma cells have invaded into the dermis. It is the second most common form of melanoma

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. In RIP, it advertises the pseudonetwork 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 through the appropriate device. When default information is passed through a dynamic routing protocol, no.

  1. Annular granular structures and gray pseudonetwork appeared to be the main features of the regressing stage; these features seemed to progress to blue-gray fine dots in the late regressing stage. Blue-gray dots or globules reflecting melanophages, the hallmark dermoscopic features of LPLK, were believed to resolve in approximately one to two.
  2. If the router has a directly connected interface onto the specified network, the dynamic routing protocols running on that router will generate (or source) a default route. For RIP, this is flagged as the pseudonetwork; for IGRP, it is the network itself, flagged as an exterior route. Command Mode. Global configuratio
  3. Erythematous pseudonetwork (Figure 2B) was the most specific of 4 dermoscopic signs evaluated. On dermoscopy, the normal superficial vascular plexus is seen as a regular blurred network of wide vessels. When AK forms, edema and elastosis develop, producing a dermoscopic pattern of erythematous pseudonetwork
  4. Results: There were statistically significant decreases in the positive rates of dermoscopic features including scales (P < 0.001), follicular plugs with whitish halo (P = 0.013), and red pseudonetwork (P = 0.022) among patients treated with ALA-PDT. Dermoscopic feature was significantly associated with pathological grade (P < 0.001)
  5. The inner gray halo is a subtle gray or beige halo that surrounds follicular openings and meshes with the pseudonetwork that is characteristic of pigmented actinic keratoses. Overall, dermoscopy can be a helpful tool to help differentiate lentigo maligna from other entities; however, sensitivity and specificity depends on the level of clinician.
  6. Dermatoscopy mainly showed a pseudonetwork or uniform areas of brown pigmentation, brown or blue-gray dots, red dots and/or telangiectatic vessels. In the epidermis, histopathology showed a mild hydropic degeneration and focal melanin hyperpigmentation. Melanin can be found freely in the dermis or laden in macrophages along with a mild.
  7. Most cases (76%) showed pinkish background with residual solar lentigo at the initial visit. Other features were also present in varying degrees. Light brown pseudonetwork disappeared and pinkish areas decreased over time. Annular granular structures, gray pseudonetwork, and fine blue-gray dots were the main features of the regressing stage

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

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.

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.

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.
