Papulosquamous disorders comprise a group of dermatoses that have distinct morphologic features. The characteristic primary lesion of these disorders is a papule, usually erythematous, that has a variable amount of scaling on the surface. Plaques or patches form through coalescence of the primary lesions. Some common papulosquamous dermatoses are pityriasis rosea, lichen planus, seborrheic dermatitis, tinea corporis, pityriasis rubra pilaris, psoriasis, and parapsoriasis. The etiology, diagnosis, and treatment of pityriasis rosea, lichen planus, and seborrheic dermatitis (including seborrheic dermatitis associated with AIDS) are discussed in this chapter. Also discussed are the diagnosis and treatment of pityriasis rubra, parapsoriasis (pityriasis lichenoides and small- and large-plaque parapsoriasis), and erythroderma. This chapter includes color photographs of the aforementioned dermatoses plus the Koebner phenomenon, lichen planus of the mucous membranes, and erythroderma in Sézary syndrome. This review contains 11 highly rendered figures and 79 references.

Introduction: Some of the typical skin diseases, such as Pemphigus vulgaris, Pemphigoid mucosae oris, Erythema exudativum multiforme, Sclerodremia, Dermatitis herpetiformis-Duhring and Lichen planus, can cause swelling and irritation in mucous membranes of the oral cavity. Aim: The aim of the study was to precise diagnosis and treatment of oral Lichen planus manifestations. Methods: Analyzing the literature data and the experience of clinicians, the most common oral lichen planus manifestations were investigated. Results: This disease most commonly occurs in middle-aged patients (30-60 years) and is more common in women than in men. Oral Lichen planus is rarely seen in children. The disease presents in 0.5% to 2% of the population. Clinical history established the relation between oral Lichen planus and oral carcinoma, and therefore this disease should be considered a precancerous lesion. Conclusion: Dermatoses in the mouth are localized most often in the oral mucosa, both at the height of the occlusal line and in the mucous membrane of the retromolar area, but they can also occur in the mucous membranes of the tongue, the floor of the mouth and lips.

<p class="abstract"><strong>Background:</strong> Papulosquamous dermatoses is a complex group of disorder characterized by scaly papules and plaques. There is a need to study the exact, pattern and prevalence of this disorder in different age groups and their line of treatment. Objective of the study was to observe the clinical pattern of various papulosquamous dermatoses and their prevalence at tertiary care center, Ujjain.</p><p class="abstract"><strong>Methods:</strong> This was an observational study done in R.D. Gardi Medical college, Ujjain over a period of one year. A total of 229 cases including male and female of papulosquamous dermatoses were enrolled from the outpatient department. All patients were studied clinically and relevant data was recorded. Microsoft excel was used for data entry and analysis was done using SPSS version 23.<strong></strong></p><p class="abstract"><strong>Results:</strong> There were 139 (60.7%) males and 90(39.3%) females with overall male to female ratio was 1.54:1. Most common age group affected with papulosquamous dermatoses was 31-50 years. The clinical pattern observed was psoriasis 49.3%, lichen planus 24.5% followed by pityriasis rosea 10.5%. The least common papulosquamous diseases were pityriasis rubra pilaris (1.3%) and lichen nitidus (1.3%). Most common variant of psoriasis and lichen planus was chronic plaque and classical respectively. Classical juvenile variant of pityriasis rubra pilaris was seen in our study. A single rare case of lymphomatoid papulosis was noted in our study.</p><p class="abstract"><strong>Conclusions:</strong> Psoriasis, lichen planus and pityriasis rosea were commonest papulosquamous diseases were observed but still we need more longer duration of observational studies on papulosquamous dermatoses to understand the morphological features for the effective management of these diseases.</p>

BACKGROUND Psoriasis is a chronic skin condition, which can have varied presentation either per se or because of various treatment modalities, which can closely simulate any different dermatological conditions. Hence, a clinicohistopathological correlation is necessary for confirmation of diagnosis and treatment. Very few studies are available in the indexed journals on this subject matter. The present study is aimed to study the clinical and histological features of psoriasiform dermatitis and psoriasis. METHODS This was a longitudinal study consisting of 60 subjects divided into two classes based on clinical diagnosis. Class A patients with diagnosed psoriasis and class B subjects with psoriasiform dermatitis. Many patients have had specific examination and skin biopsy. RESULTS Majority of the cases (40 %) were in the age group of 31 - 40 years. Most common clinical diagnosis was psoriasis (56.7 %) followed by allergic contact dermatitis (13.3 %), pityriasis rosea (8.3 %), lichen simplex chronicus (5 %), seborrheic dermatitis (3 %), Devergie’s disease (3 %), and pityriasis lichenoides chronica (1.6 %). Clinicopathological concordance with psoriasis was seen in 68 cases (68 %) and discordance in 32 cases (32 %). CONCLUSIONS Clinically psoriasis vulgaris can be diagnosed (> 80 %) by presence of micaceous scales, along with grattage test and Auspitz’s sign. But in few, morphological variants of psoriasis and psoriasis modified due to various treatment modalities, we may not see the classical presentation and may mimic various other conditions (psoriasiform dermatitis), in which case a histopathological conformation is essential for diagnosis and treatment.

AbstractIntroduction:Rhinosporidiosis primarily affects the mucous membranes of the nose and nasopharynx. The disseminated form of this chronic fungal disease is extremely rare.Case report:The authors present a case of disseminated rhinosporidiosis in an immunocompetent patient with involvement of the skin, subcutaneous tissue, muscle, bone, penis and urethra, and with a long-standing primary lesion in the nose.Discussion:A late or atypical presentation of rhinosporidiosis may cause diagnostic dilemma. Fine needle aspiration cytology of the tumoural lesions may establish the diagnosis. Histopathology is confirmatory. The subcutaneous masses may be solid or cystic. Ulceroproliferative lesions need to be differentiated from malignancies.Conclusion:This is the first reported case of truly disseminated rhinosporidiosis with simultaneous involvement of multiple anatomically unrelated sites in a single patient. This is also the first reported case of cystic rhinosporidiosis. The possibility and sequelae of spontaneous regression of rhinosporidiosis are also discussed.

THIS DISCUSSION of dermatologic therapy contrasted the opinions of an empiricist, Dr. Perlman, with those of a nihilist, Dr. Falk. Both speakers based their comments upon personal experience. Participants were forewarned that these remarks would frequently be contrary to classic dermatologic teaching. Histologic examination reveals that the infant's skin lacks a well-developed stratum corneum. This keratinized outer layer of the epidermis is loosely organized and lace-like, thereby providing a poor defensive barrier against the entrance of bacteria. Poor cornification also explains the frequency of weeping, exudative dermatoses during infancy. Fungus infections of the skin are rare during infancy because the loose stratum corneum does not provide a favorable surface for superficial growth of fungi. The delicacy of the infant's skin and its scanty protective cornification make it particularly vulnerable to damage by overtreatment. Indeed, 40% of the dermatoses seen by dermatologists today are due to the effects of overly-enthusiastic topical therapy. Dermatologic problems commonly seen by pediatricians were discussed under the following general headings: (1) Eczematous dermatoses: contact dermatitides, dermatitis venenata (poison ivy), diaper dermatitis, intertrigo, infectious eczematoid dermatitis, atopic dermatitis, atopic erythroderma, nummular eczema and circumscribed neurodermatitis. (2) Pyodermas: dermatitis exfoliativa neonatorum (Ritter's disease), impetigo contagiosa, ecthyma, erythema streptogenes, dermatitis gangrenosum infantum and periporitis staphylogenes. (3) Maculopapular squamous dermatoses: pityriasis rosea, seborrheic dermatitis (cradle cap), psoriasis, parapsoriasis, lichen planus, pityriasis rubra pilaris, lichen nitidus and lichen striatus. Comments regarding the diagnosis and treatment of certain of these conditions, which seemed to be of special interest to participants in the round table discussion, follow. DERMATITIS VENENATA (POISON IVY) The irritant principle of poison ivy is a dihydric phenol, urushiol, a catechol-like substance which is contained in every portion of the poison-ivy plant, including leaves, stem, flowers and fruit.

We report a case of mucocutaneous leishmaniasis caused by Leishmania viannia braziliensis. Despite several courses of both oral and intravenous antibiotics no improvement was seen. This case highlights the importance of taking a thorough history, including details of recent travel, and considering rarer causes when no improvement with antibiotics is seen. Our patient was infected with a particularly virulent strain and destruction of the mucous membranes is not uncommon. Rapid diagnosis and treatment are therefore crucial.
