Uncovering subtle nail involvement in lichen planus with

  1. Dermoscopy may be helpful in evaluation of disease progress and prognosis as the manifestations of nail matrix, nail bed and perionychium involvement can be observed clearly with this technique . Nail LP may have a very progressive course, so early diagnosis and proper treatment are important [ 1 ]
  2. The dermoscopic features of cutaneous LP are typified by the presence of a dull red background, white crossing streaks of WS (multiple patterns), and mixed pattern of dotted and linear vessels at the periphery of the lesions 1 - 5. OLP may occur in isolation, or in association with cutaneous and/or nail LP
  3. ation reveals characteristic interface dermatitis. Dermoscopy is a non-invasive tool, useful in the assessment of.

Nail dermoscopy (onychoscopy) is a non-invasive diagnostic tool helpful in differential diagnosis of nail apparatus pigmentation. In the Caucasian population melanocytic melanonychia occurs relatively rarely. More common causes (about 80%) of dark nail pigmentation are haematomas and nail infections LP shows a plethora of patterns in dermoscopy. Background color is blue or purple and white scales can be seen in the center or periphery of the lesion. Scales are dull white. Dotted and linear vessels are, respectively, noted in the center and periphery b. Follicular structures are unaffected in classical LP CUTANEOUS LP Classically described as small, violaceous, polygonal, flat-topped papules and plaques on glabrous skin (Figure 4). A fine white, reticulated scale or punctae (Wickham's striae) may be appreciated with dermoscopy. Commonly affected areas include the flexural surface of arms, legs, and wrists Lichen planus (LP) is a chronic autoimmune mucocutaneous disorder which most frequently affects middle-aged adults of both sexes. LP can affect oral and genital mucosa, skin, scalp and nails. 2 WS are the hallmark sign of LP and correspond histologically to focal thickening of the granular layer. In this particular case, WS were visible to the. Lichen planopilaris is suspected on the clinical presentation and careful examination of the mouth, nails and skin for evidence of lichen planus elsewhere. Trichoscopy reveals absent follicles, white dots, tubular perifollicular scale and perifollicular erythema. The diagnosis may be confirmed on a scalp biopsy that includes hairs with.

Lichen planus affects one or more nails, sometimes without involving the skin surface. It is called twenty-nail dystrophy if all nails are abnormal and nowhere else is affected. Lichen planus thins the nail plate, which may become grooved and ridged. The nail may darken, thicken or lift off the nail bed (onycholysis) Conclusions: LP is more common in young adults and shows a male preponderance. WS is the most important diagnostic feature seen on dermoscopy of all the cutaneous types of LP excluding LPP. Interface dermatitis with a band of lymphocytic infiltrates and dermal melanophages is a notable feature of histopathology of LP Nail dermoscopy (onychoscopy) is a versatile tool that is relatively new to the practice of dermatology. The goal of onychoscopy is to improve diagnostic skill in nail disorders. This chapter covers the technique and current knowledge of features observed in various nail disorders of inflammatory, traumatic, infectious, and neoplastic origin Background: Lichen planus (LP) is an autoimmune dermatosis characterized by pruritic violaceous flat-topped polygonal papules predominantly over the extremities but can also affect trunk, mucosa, scalp, palms, soles and nails. Dermoscopy is a novel non-invasive imaging modality and the presence of salient dermoscopic features will help to. Dermatoscopy is a relevant in vivodiagnostic tool for inflammatory diseases of the skin that aids not only in diagnosis, but also in monitoring the response to treatment. The inflammatory diseases show dermoscopic patterns involving the vessels, scales, follicles, background hue, and special clues

Background Dermoscopy has furthered advances in the differential diagnosis of longitudinal melanonychia; however, fewer details observed in the nail, as compared to skin lesions, make interpretation difficult. Methods Ten cases of longitudinal melancholia, from several etiologies, were submitted to direct dermoscopic examination of the nail bed and matrix. Results We observed the presence of. Lichen planus is a chronic inflammatory pruritic disease affecting skin, mucous membranes, hair follicles and nails. Dermoscopy have potentially improved the diagnosis of skin diseases by defining specific patterns. We report a case of 34 year-old man with penile lichen planus diagnosed by dermoscopy

Dermoscopy of the cutaneous lesions predominantly shows gray granular pigmentation, (LP) and nail lichen striatus is essential as clinical differentiation is challenging at times. Onychoscopic features of nail LP include: trachonychia, chromonychia, pitting, fragmentation of the body of the nail, splinter hemorrhages,. Lichen planus (LP) is an inflammatory condition that can affect skin, mucous membranes, hair follicles, and/or nails. Nail abnormalities are estimated to occur in around 10% of LP cases. Clinical characteristics of nail involvement have been the subject of very few studies, which have mainly focused on isolated nail LP

Dermoscopy is a method of visualizing subsurface skin patterns. The dermoscopic examination of LP helps in clinching the diagnosis and noting the improvement during follow-up. However, these features may vary in patients with fair and dark skin To our knowledge, there is a single case report of dermoscopy of LP of the lower lip in the Korean language. 3 In view of the risk of malignant transformation, early diagnosis and active early treatment are necessary. 4 Only, a few studies have described isolated LP of the lips until now. 4 We report this case describing dermoscopy of oral LP. In LP lesions the background was violet in 45.5% and 58.2% revealed Wickham striae. In PR lesions a dull red background was found in 50.0%, white scale in 83.3%, but no vessels were detectable. Conclusion: Dermoscopy features in PP, LP, and PR in dark skin are mostly similar to those in light skin Dermoscopy also proved useful in conveniently ruling out other disorders typified by mucosal and nail pigmentation such as Laugier Hunziker syndrome and drug-induced changes. Although direct oral microscopy has been used in defining features of oral lichen planus, to the best of our knowledge this case is the first report on mucoscopy or.

  2. LP is a common papulosquamous disorder involving the skin, nails, and mucosae. HLP is a subacute or chronic variant of LP characterized by hypertrophic or warty lesions, most commonly found on the pretibial area of the lower limbs. HLP on the legs tends to persist and has a propensity for malignant transformation even in young patients
  3. Nail LP is more commonly seen in children . One study reported a prevalence of 19% in a cohort of 100 childhood LP cases from India . Tosti and coworkers noted that nail LP may be underdiagnosed in children because of the fact that isolated nail lesions are more common in this age group

Lichen planus pigmentosus (LPP) is considered a rare variant of lichen planus (LP). It is characterized by acquired dark brown to gray macular pigmentation located on sun-exposed areas of the face, neck, and flexures, commonly found in dark-skinned patients. In patients with LPP, an inflammatory lic In annular LP, peripheral round white WS are present, whereas in hypertrophic LP, WS are absent but comedo-like openings (CLO) filled with yellow keratinous plugs can be seen along with peripheral white striations, bluish-gray globules and yellowish structures. Dermoscopy of nail shows erythronychia disrupting the lunula and distal nail. Of all LP cases, 1-4% are diagnosed in childhood with the earliest case reported in a 3-month-old infant (3). In the study performed by Kanwar et al. (4) LP was diagnosed in 5% of the outpatient paediatric population and the nails were involved in 19% of the children. Only one patient had isolated nail changes, but classic LP lesions evolved. LP affecting the hair follicles and the nail bed will often lead to permanent scarring resulting in islands of alopecia and pterygium formation with eventual loss of the nail plate. 2, 14. LP onset is usually acute with initial lesions almost always appearing on the extremities. A generalized eruption, in approximately one-third of the cases.

Introduction. Initially described by Pringle in 1895, lichen planopilaris (LPP) is a cutaneous disorder selectively involving hair follicles with a lymphocytic inflammatory process that eventually destroys the follicles leading to expanding areas of scarring alopecia (cicatricial alopecia). Together with frontal fibrosing alopecia (FFA) and. Atypical case of lichen planus recognized by dermoscopy. Lichen planus (LP) is an inflammatory disease that affects the skin—mainly the extremities and the trunk—the mucous membranes, the genitalia, the nails and the scalp.

  1. Background: Lichen planus (LP) is an immune_mediated, chronic inflammatory disease involving skin, oral and genital mucosa, nails, and hair with several morphologic variants. The exact etiology remains unclear, but several factors have been implicated. Purpose: To study the clinico-epidemiological profile of patients of LP and its clinical variants and to find out whether LP is relatively.
  2. Lichen planus (LP) is a chronic inflammatory and immune-mediated disease that affects the skin, nails, hair, and mucous membranes. It is not an actual lichen, and is only named that because it looks like one. It is characterized by polygonal, flat-topped, violaceous papules and plaques with overlying, reticulated, fine white scale (Wickham's striae), commonly affecting dorsal hands, flexural.
  3. LP of the nails occurs in approximately 10% of patients and typically affects multiple nails without necessarily affecting the nearby skin. Thinning of the nail plate and longitudinal ridging are the first signs of disease. While in the clinic, dermoscopy allows visualization of Wickham striae in most cases.

The human nail shields the distal digit from harm, assists in the picking-up of small objects, improves fine touch, and enhances the aesthetic appearance of the hand [ 1 ]. Aesthetically displeasing nails and nail-associated symptoms such as pain or throbbing are common factors that contribute to a patient's decision to seek medical attention 6,15 Practical tips: Diagnosis • Dermoscopy facilitates the recognition of lichen planus, by revealing the pathognomonic WS (Fig. 1).6,16 Since WS can be also detected in genital LP, dermoscopy enhances its differentiation from other diseases of the genital area (such as warts, psoriasis, and balanitis).17 • Dermoscopy enhances the.

Dermoscopy, also known as dermatoscopy, epiluminescence microscopy, or skin surface microscopy is a non-invasive, in-vivo technique that has traditionally been useful for the evaluation of suspicious skin lesions. It can help identify lesions and differentiate melanocytic lesions from dysplastic lesions, melanomas, or non-melanoma skin cancers. Lichen planus Treatment. There is no universally effective treatment for lichen planus. Topical and systemic corticosteroids are the mainstay of therapy. Prednisone for generalized skin or erosive mucosal involvement; a 4-week course starting at 1 mg/kg/day and gradually decrease of the dosage. Group I or II topical steroids twice daily are. Psoriatic Nails. Psoriasis, a chronic inflammatory immune-mediated disease involving the skin, the nails, and the musculoskeletal structures, affects 1% to 3% of the world population. 1,2 Approximately 25% of persons with psoriasis develop the disease before 20 years of age. 3 Plaque psoriasis or psoriasis vulgaris, the most common variant, is characterized by sharply demarcated erythematous. The condition is diagnosed clinically, and, if needed, diagnosis can be confirmed with a punch biopsy. 4-6 When LP is suspected, dermoscopy may be used to look for Wickham striae on the surface of. The nail matrix is destroyed by the inflammation and replaced by fibrosis. The proximal nailfold fuses with the proximal portion of the nail bed. Dermoscopy can show pitting of the nail matrix, tachyonychia, chromonychia, onycholysis, or splinter hemorrhages. LP may be a cause of some cases of 20-nail dystrophy of childhood

One developed after the diagnosis of lichen sclerosus and another where the lentigo appeared first.3 Although central hyperpigmentation was described in a large case series of annular LP, dermoscopy and histology were not reported.1 The pathogenesis of genital lentigo is unclear, as chronic UV exposure by analogy to lentigo simplex of other.

Nail plate dermoscopy The nail plate presents a homogeneous, pale red, longitudinal band extending from the proximal nail fold to the distal edge. The proximal border of the band has a characteristic convex shape and its distal part may appear white because of onycholysis. The band may contain one or more longitudinal, dark red-to-black streaks. Lichenoid keratosis (LK) is a common benign skin growth that typically presents as an evolving single discrete papule on the trunk or upper extremities of adults (Figure 1). LK occurs almost always as a solitary skin growth; however, two or three lesions can occasionally be present. Approximately 8% of patients with LK will have two discrete. Lichen planopilaris (LPP), also known as follicular lichen planus, is a clinical syndrome consisting of lichen planus (LP) associated with cicatricial scalp alopecia.

Drug-Induced Lichen Planus is an uncommon condition that occurs due to certain medications (side effect). It is also known as Lichenoid Drug Eruption (LDE) It mainly manifests as skin lesions on the arms, legs, and trunk. Though, in many individuals the condition is asymptomatic, in some there may be itching from lesions on the skin and pain. Hypertrophic Lichen Planus are characterized by thick skin lesions that occur on the arms and legs, particularly around the hands and feet. In general, individuals in the 30-60 year age group are affected the most. The main symptom of these lesions is itching Lichen planus (LP) most commonly presents as itchy, shiny, reddish-purple spots (lesions) on the skin (cutaneous LP) or as white-gray lesions in the mouth or on the lips (oral LP). Less commonly, LP may also involve the genitals (penile or vulvar LP), scalp (lichen planopilaris), ears (otic LP), nails, eyes and esophagus Part I The Normal Nail and Nail Signs 1 1 Science of the Nail Apparatus 1 David de Berker, Beth S.

Lichenoid dermatoses. Due to cell-mediated autoimmune reaction toward basal layer keratinocytes; may be idiopathic, drug-related or infection-related (HCV) Often lasts 1-2 years (except oral and hypertrophic forms, which typically have protracted courses) Presents with intense pruritus and violaceous, smooth flat-topped papules and plaques. LP, in contrast to LN demonstrates a predominance of CD4+ helper T-cells along with HECA-452 staining as well as a more uniform lymphocytic infiltrate [1,6]. Although histology and clinical presentation are characteristic; features of dermoscopic findings are notable and thus, dermoscopy may provide to be a useful too1 [ 1 ] Onychomycosis is a fungal infection of the toenails or fingernails that may involve any component of the nail unit, including the matrix, bed, or plate. Onychomycosis can cause pain, discomfort, and disfigurement and may produce serious physical and occupational limitations, as well as reducing quality of life vaginal and gingival LP lesions. The disorder is known as vulvovaginal-gingival lichen planus (VVG-LP) or vulvovaginal-gingival syndrome (1, 2). The terms: oro-vaginal-vulval LP and plurimucosal LP have been used by some authors as alternative names for the condition. A counterpart of this disease in men is termed peno-gingival LP (3-5) Background: Numerous studies have attempted to apply artificial intelligence (AI) in the dermatological field, mainly on the classification and segmentation of various dermatoses. However, researches under real clinical settings are scarce.Objectives: This study was aimed to construct a novel framework based on deep learning trained by a dataset that represented the real clinical environment.
