Papulosquamous diseases are characterized by well-demarcated areas of papules and scale, typically on an erythematous background. The differential diagnosis includes psoriasis, lichen planus, mycosis fungoides, discoid lupus erythematosus, eczema/dermatitis, drug eruptions, tinea, pityriasis versicolor, secondary syphilis, and pityriasis rosea. The presence of significant pruritus is a useful marker to help with the differential diagnosis: lichen planus and discoid eczema are typically pruritic, whereas others, such as psoriasis, are less so. The distribution is also key to diagnosis, with psoriasis often showing characteristic symmetrical involvement of the extensor surfaces, scalp, and nails. Histology can be essential to reach a diagnosis and plan an appropriate approach to management.

High Index Of Suspicion

<p class="abstract">Presentation of two papulosquamous disorders in a same individual is rare condition till date. Independently, psoriasis and Lichen planus (LP) are common inflammatory skin conditions affecting around 2-3% and 1% of HIV (Human immune deficiency) positive population respectively. As reviewed in the literature, psoriasis may be independently associated with other autoimmune conditions like vitiligo, alopecia areata, lichen planus, and discoid lupus erythematosus. In this article, we presented a case report of a HIV seropositive patient who suffered from psoriasis and lichen planus. The coexistence of psoriasis and lichen planus in one individual is rare and underreported in literature. Psoriasis or lichen planus may be the presenting feature of HIV infection and tends to be more severe, to have atypical presentations. Psoriasis and lichen planus can be coexistent or successionally appear one after other in one individual though rare presentation. High index of suspicion is always required while dealing with papulosquamous lesions in PLHIV.</p><p> </p>

Dermatoscopy is a valuable auxiliary non−invasive method used in the diagnosis of inflammatory, parasitic and viral skin diseases. Treatment of dermatoses is based on the results of analysis of melanin, follicular−horny and vascular components. Diagnosis begins with polarized dermatoscopy and then progresses to non−polarized using immersion fluid. At dermatoscopic inspection of a psoriatic plaque the point vessels evenly distributed along all the surface (a symptom of "scattered red pepper") are noted. Eczema is characterized by focal accumulation of blood vessels in the form of dots, peeling, yellowish crusts. Examination of discoid lupus erythematosus foci often reveals individual linear or branched vessels, their location is random. Red herpes zoster is dermatoscopically characterized by vascular structures in the form of large granular horny plugs of whitish color with a pearly sheen. The most informative is dermatoscopy in the differential diagnosis of erythematous form of rosacea and seborrheic dermatitis. On the erythematous background, dilated vessels around the sebaceous hair follicles, large vascular polygons formed from vessels thicker than in healthy skin and seborrheic dermatitis are found. At inspection of the fresh centers of a sclero−atrophic lichen diffuse unstructured zones of white color with a peripheral erythematous corolla and with numerous light comedic structures on a surface are visualized. At dermatoscopy of the Little − Lassueur syndrome in follicular papules on skin gray, violet points located in the form of a circle are noted. Dermatoscopy is increasingly used in dermatology, especially in the differential diagnosis of dermatoses of inflammatory and parasitic nature.

Discoid lupus erythematosus (DLE) is an inflammatory autoimmune disease leading to scarring and hair loss. Linear Discoid lupus erythematosus has been mentioned in the literature as a rare variant. This article describes isolated linear DLE of the scalp. We present a 26-year-old Saudi male who had unilateral linear DLE of the scalp with no involvement of other body sites and no systemic manifestations. This case is the first case of isolated linear DLE on the scalp. This presentation should be considered as a differential diagnosis of linear scarring alopecia as a distinct morphological pattern of DLE.
