, which is characterized by itchy, non-inflammatory, concentric rings Persistent anecdotal reports of offshore fishes exhibiting skin lesions and other symptoms began in the winter of 2010-2011, following the Deepwater Horizon blowout and resulting oil spill (April 20-July 15, 2010; Lubchenco et al. 2012; McNutt et al. 2012).Open skin lesions are a relatively rare occurrence in wild marine fish populations (van Banning 1987; Ziskowski et al. 1987), being. Polycyclic (Multiple Rings). Skin lesions of this classification appear in groups of round circles The diagnosis can be made clinically based on the presentation of skin lesions with arthritic symptoms and colicky abdominal pain. If clinical findings are inconclusive, a complete blood count,.. Primary skin lesions: the initial recognizable skin lesion or basic skin changes (macule, papule, patch, Polycyclic interlocking or coalesced circles psoriasis Morbilliform measles-like; maculo-papular lesions with roseola, mononucleosis confluence on the face and body Border/Margin.
Skin lesions appear during the second half of the menstrual cycle and resolve during the menstrual period Urticaria, urticaria-like weals, eczema-like lesions, blisters and target lesions may occur It is prevented when ovulation is prevented by an oral contraceptive agen The skin lesions may range from a measles-like rash to target-like skin lesions. Acute haemorrhagic oedema of infancy, which occurs in children under the age of 2, is a form of urticarial vasculitis. The rash begins as a red raised lesion and then changes to the typical targetoid appearance, with a purplish colour
A papule (figure 3-4) is a solid, elevated lesion usually 0.5 cm to 1 cm or less in diameter. Most of the lesion is above the level of the surrounding skin rather than deep within the skin. Many skin diseases start with papules--warts, psoriasis, syphilis, drug eruptions, and some phases of acne The Cunliffe (TP) General Dermatology Diagnostic Tool.

Diagnosis based on predominant site. Diagnosis based on morphology (appearance of rash / skin changes The incidence of skin lesions in 2011 sampling was most frequent in some bottom-dwelling species along the continental shelf edge north of the Deepwater Horizon site. Longline surveys revealed that by 2012 the overall frequency of lesions in northern Gulf of Mexico (NGM) fishes in the vicinity of the Deepwater Horizon had declined 53%, with. Prevalence of External Skin Lesions and Polycyclic Aromatic Hydrocarbo by Steven Murawski, William T. Hogarth et al. We surveyed offshore fish populations in the Gulf of Mexico in 2011 and 2012, following persistent reports of abnormal skin lesions and other pathologies in the aftermath of the Deepwater Horizon oil spill papulosquamous lesion is a papule with desquamation (scaling). Nodules are forms of papules, but are larger and deeper. They may be located in the dermis or subcutaneous tissue, or in the epidermis. Nodules are usually ½ cm. or more in diameter. Ex: Metastatic neoplasm; xanthoma An elevated area of skin 2 cm. or more in diameter. It may be formed by a coalescence of papules or nodules. The surface area is greater than its height. It is a plate-like lesion
Annular lesions can present in a variety of diseases. Knowledge of the physical appearance and history of presentation of these skin findings can help in the diagnosis. A pruritic, annular. Hydrocarbon keratosis (pitch keratosis, tar keratosis, tar wart) is a precancerous keratotic skin lesion that occurs in people who have been exposed to polycyclic aromatic hydrocarbons. There are several other forms of keratosis, most of which are very rare. Keratosis can occur on the palms of the hands and soles of the feet

Inset: A close-up photograph shows a lesion on the skin of a red snapper caught in Gulf waters of polycyclic aromatic hydro-carbons in golden tilefish and a high occurrence of skin lesions..14 (C-IMAGE/Susan Snyder Annular erythema is not a diagnostic term but rather a description of a spreading erythematous eruption with an annular (ring-shaped) appearance. If the expansion of the rash is not uniform it may become arciform (arc-like) or polycyclic (two or more connected rings). While there are many dermatoses that have an annular appearance, the term annular erythema is sometimes reserved for a group of. Lesions can also be annular or polycyclic Conditions associated with generalised peeling In addition to the Staphylococcal Scalded Skin syndrome, Stevens Johnson syndrome / toxic epidermal necrolysis, and pustular psoriasis, generalised skin peeling can follow on from a number of widespread inflammatory and bullous eruptions
Annular Lesions. Am Fam Physician. 2005 Aug 15;72 (4):671-672. A 57-year-old man presented with a three-week history of a red, ring-like rash on the thighs, hips, and flexor surfaces of his arms. Common shapes encountered in dermatologic diseases include linear, nummular, annular, polycyclic, and arciform. The last three have a relatively restricted differential, which must be entirely explored. It is not uncommon for a single disease to present in annular, arciform or polycyclic configurations; moreover, the lesions may evolve from being arciform to annular and then become polycyclic Skin lesions occur anywhere on the body, especially the upper body, and are highly variable in appearance; Lesions can be inflamed papules, scaly plaques, fluid-filled bullae or ulcerated. Lesions are often and annular / polycyclic lesions with blistering around the edge known as the 'string of pearls' sig Erythema multiforme is an acute, typically self-limited skin condition with lesions that can be isolated, recurrent, or persistent.1 Erythema minor affects only the skin and erythema major.
Two months after starting treatment, the facial skin lesions became aggravated. At that time, CIDP also became aggravated, and immunosuppressant azathioprine was prescribed at the Department of Neurology. The clinical feature of the facial lesions became polycyclic and erythematous over time and differed from the preexisting ones (Fig. 1B, C) The skin lesions were accompanied by inflammation and immunological imbalance and resembled typical atopic dermatitis. We demonstrate that constitutive activation of the AhR pathway causes inflammatory skin lesions and suggests a new mechanism for the exacerbation of inflammatory diseases after exposure to occupational and environmental. Patient gave history of recurrent rhinitis since childhood however there was no family history of atopy or similar skin lesions. Cutaneous examination revealed widespread erythematous, serpiginous, annular and polycyclic, scaly plaques over face, trunk, upper and lower extremities [Figure 1] and [Figure 2] Learnderm.org does not support your web browser (Internet Explorer 7 and below).

The skin lesion was aggravated and became polycyclic and erythematous; after azathioprine was added, her chronic inflammatory demyelinating polyneuropathy became aggravated. A second biopsy confirmed hyphae in the cornified layer Purpura: a skin rash composed of petechia, doesn't blanch on pressure. Telangiectasia: localized dilated blood capillaries visible to naked eye, red, spidery, blanches on pressure. General lesions Patient gave history of recurrent rhinitis since childhood however there was no family history of atopy or similar skin lesions. Cutaneous examination revealed widespread erythematous, serpiginous, annular and polycyclic, scaly plaques over face, trunk, upper and lower extremities [Figures [Figures1 1 and and2]. 2 ] Secondary skin lesions: Erosion: discontinuity of the skin with incomplete loss of the epidermis without penetration below the dermal-epidermal junction. Ulcer: complete loss of the epidermis and portions of the dermis and subcutaneous fat resulting in a scar. Fissure: narrow linear crack/split in the skin, extending through the epidermis.
Usually skin lesions refractory to topical treatment respond well to drugs used for systemic therapy of lupus erythematosus. LE-specific skin lesions generally respond well to treatment with antimalarials such as hydroxychloroquine or chloroquine, which may be combined with quinacrine. 71 In the case of poor clinical response to antimalarials. In 1979, Griffin and colleagues were the first to report a skin disease of dogs that resembled discoid lupus erythematosus (DLE), one of the variants of cutaneous lupus erythematosus (CLE) of humans .Within the ensuing two decades, new information was limited to a large case series of canine DLE [2,3,4] and a catalog of skin lesions present in dogs with systemic lupus erythematosus (SLE)  Cutaneous lesions account for four of these 11 revised criteria of SLE. Skin lesions in patients with lupus may be specific or nonspecific. This paper covers the SLE-specific cutaneous changes: malar rash, discoid rash, photosensitivity, and oral mucosal lesions as well as SLE nonspecific skin manifestations, their pathophysiology, and management
Initial presentation Most skin lesions evolve over time, although this varies from minutes with urticaria to weeks or even months with psoriasis or cutaneous T cell lymphoma. Change in lesion Determining whether there has been a change from the initial appearance of a lesion provides diagnostic clues Skin lesions appear between 3 and 30 days after tick attachment, with an average of 9 days. •. The primary lesion is an annular ring of erythema, with variable induration (erythema chronicum migrans), which expands at a rate of 1 to 2 cm/day and may reach up to 60 cm in greatest diameter ( Fig. 16.5 ).

The lesions are typically annular or polycyclic and may become confluent Paraneoplastic pemphigus The pemphigus family is a rare group of immunobullous conditions affecting skin and/or mucous membrane Dermatologic Physical Examination. The four components of the dermatologic physical exami nation are (1) primary lesions, (2) secondary lesions, (3) distribution, and (4) configuration. Because primary and secondary lesions are rather constant with most dermatitides, they should be relied on heavily to lead to the correct diagnosis Annular, arciform, and polycyclic lesions formed in many cutaneous conditions (urticaria, erythema annulare, granuloma annulare, etc.). The clinical photo on the right shows a patient with erythema annulare centrifugum who has many arcs and circles as part of this condition Erythema annulare centrifugum (EAC), is a descriptive term for a class of skin lesion presenting redness in a ring form (anulare) that spreads from a center (centrifugum).It was first described by Darier in 1916. Many different terms have been used to classify these types of lesions and it is still controversial on what exactly defines EAC
ECM should not be confused with erythema annulare centrifugum (left) or erythema multiforme minor (right).

Section of skin from raised erythematous border of polycyclic lesion showing collections of neutrophils in the dermal papillae. There is no evidence of leukocytoclastic angiitis This procedure for classification of pigmented skin lesions was agreed on at an international consensus meeting . In the first step it has to be determined whether a melanocytic or non-melanocytic tumor is present. In case of a melanocytic lesion, the differentiation between benign or malignant/suspicious lesions follows in a second step 57. SHAPE OR CONFIGURATION OF SKIN LESIONS Annular ;Ring-shaped Round/nummular/disc oid ;Coin-shaped; usually a round to oval lesion with uniform morphology from the edges to the center Polycyclic; Formed from coalescing circles, rings, or incomplete rings urticaria, 58 Generally, DM skin infiltrate is rare and mainly includes CD4 + T lymphocytes, some macrophages, plasmacytoid dendritic cells, histiocytes, plasma cells, and eosinophils. 26 Ito et al 105 reported a case of specific DM skin lesions on the back of the hands, face, and trunk; a skin biopsy showed a diffuse infiltration of neutrophils through the.
Figurate skin eruptions are fixed or migratory lesions, which is clinically characterized by annular circinate, arcuate, targetoid or polycyclic plaque. Although most skin lesions typical annular are dermatophytosis (ringworm), general practitioners and especially pediatricians have to consider other possible diagnoses Tinea imbricata is an unusual form of tinea corporis caused by the strictly anthropophilic dermatophyte Trichophyton concentricum [ 1 ]. Individual lesions appear on the skin as itchy, noninflammatory, concentric rings that may fuse upon enlargement to form scaly polycyclic or serpiginous plaques [ 2 ] Nummular - coin shaped 9. Poikiloderma - skin that displays variegated pigmentation, atrophy and telangiectases 10. Polycyclic - formed from coalescing rings or incomplete rings 11.

Granuloma Multiforme (GM) is a reactive skin disorder with annular lesion and focal necrobiosis. It was first described in Nigeria (Africa), since than it was mostly described from various regions of Africa where leprosy was endemic. Outside Africa, this disease is rarely reported. Till 2016 only five cases were reported from India. This is the second case report from Nepal A 50-year-old male railroad worker presented to his primary care physician with an erythematous, tender skin lesion on the right knee; a biopsy of this lesion revealed squamous cell carcinoma in situ.The site of the lesion was sun-protected but had been associated with 30 years of creosote-soaked clothing Based on clinical and histological criteria, the skin lesions are divided into lupus erythematosus (LE)-specific (eTable) and LE-non-specific manifestations (e11, e12). The most frequent LE-specific manifestation is the acute cutaneous lupus erythematosus (ACLE), which may occur as a butterfly rash or in the form of a generalized maculopapular. MORPHOLOGY OF LESION • PRIMARY SKIN LESIONS: Initial pathologic change • SECONDARY SKIN LESIONS: Result from external forces such as scratching, picking, infection, or healing of primary lesions. 8. MACULE: Color change in the skin that is flat to the surface of the skin and not palpable, <1cm in size. PATCH: If >1cm in size termed Patch
The term skin lesion refers to any cutaneous surface change. The terms used to describe dermatologic lesions are unique, specific and highly important for accurate diagnosis and communication 2. Primary Lesions: Those lesions that are the direct result of a pathologic process. Macule: Small, flat, non-palpable lesion (<1 cm) Skin lesions had appeared abruptly 48 hours before the presentation. Cutaneous examination revealed prominent periorbital edema with annular purpuric patches. Annular and polycyclic urticarial lesions were noted on the trunk
Early lesion skin biopsy shows ill-defined epidermal invaginations into dermis, containing keratinocytes with little nuclear atypia and mitotic figures, and some dyskeratotic cells.
