Linear lichen planus pigmentosus is considered as a combined type of linear lichen planus and lichen planus pigmentosus (LPP), and only 4 such cases have been reported in the dermatologic literature. We report one case of linear LPP that developed on the patient’s mandibular area and the right side of the extremities. The lesions on the face presented as a dark-brown streak, which was parallel ...

Lichen planus pigmentosus (LPP) is a variant of lichen planus. It characterized by small black, brown macules, on sun exposed areas like face, neck, upper extremities and trunk. Lesions are insidious in onset with gradually progressive course. Few variants have been reported LPP inversus, localized LPP, linear zosteriform oral mucosa etc. Here, we present case young adolescent male, which rare ...

Lichen planus (LP) is a papulosquamous dermatosis that involves the skin, scalp, nails and mucous membranes. Although its pathogenesis is still unknown, there is evidence that an imbalance of immunologic cellular reactivity plays an important role. Histopathologic examination reveals characteristic interface dermatitis. Dermoscopy is a non-invasive tool, useful in the assessment of inflammatory...

Manuscript accepted for publication November 17, 2008. Abstract. We report 4 patients with relatively asymptomatic, annular brownish plaques arising in the skin creases. The lesions had remained stable for months despite many topical treatments. Histological examination revealed an atrophic epidermis with a dermal lichenoid inflammatory infiltrate showing marked pigmentary incontinence. These c...

Lichen planus pigmentosus (LPP) is a rare variant of lichen planus (LP), reported in various ethnic groups. It occurs predominantly in female in the third or fourth decade of life, characterized by insidious onset of dark-brown macules in sun exposed areas and flexural folds. The differential diagnosis may occur with druginduced pigmentation, photosensitization and vitamin deficiency like pella...

Lichen planus pigmentosus, a macular variant of lichen planus, is characterized by slate grey pigmentation and was first seen in the Indian population. We report a case of LPP with a linear distribution. A 27- year-old female presented with asymptomatic dark brown macules from the middle of right calf to the thigh consistent with the pattern of Blaschko’s lines. To the best of our knowledge, th...

Background: Lichenoid disorders are often difficult to diagnose clinically. Dermoscopy can act as an alternative technique to skin biopsy for diagnosis of various lichenoid dermatoses. Study aim: To study the correlation of dermoscopic with histopathological findings in various lichenoid dermatoses Methods: Fifty patients with clinical picture of lichenoid dermatoses were examined first under t...
