  1. Lichen planus pigmentosus describes ill-defined oval, greyish brown marks on the face and neck or trunk and limbs without an inflammatory phase. It is a form of acquired dermal macular hyperpigmentation. It can be provoked by sun exposure, but it can also arise in sun-protected sites such as the armpits
  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.

Histology of lichenoid drug eruption. In lichenoid drug reactions the pathology is nearly identical to lichen planus. There is a dense, band-like lymphocytic infiltrate in dermis that obscures dermoepidermal junction, cytoplasmic vacuolisation of basal keratinocytes and apoptotic keratinocytes that degenerate into colloid bodies (figures 1,2)

Clinical and histopathological features of lichen planus

Lichen planus is an inflammatory mucocutaneous condition with a myriad of clinical manifestations. There are 3 forms of lichen planus that effect the vulva: papulosquamous, hypertrophic, and erosive. Erosive lichen planus can progress to vulvar scaring, vaginal stenosis, and squamous cell carcinoma; Lichen planus (LP) is a chronic inflammatory disorder that most often affects middle-aged adults. LP can involve the skin or mucous membranes including the oral, vulvovaginal, esophageal, laryngeal, and conjunctival mucosa. It has different variants based on the morphology of the lesions and the site of involvement. The literature suggests that certain presentations of the disease such as.

Despite being one of the most common oral mucosal diseases and recognized as early as 1866, oral lichen planus (OLP) is still a disease without a clear etiology or pathogenesis, and with uncertain premalignant potential. More research is urgently needed; however, the research material must be based on an accurate diagnosis Histologic Findings. The histopathologic features distinguish lichen planus based on the presence of irregular acanthosis and colloid bodies in the epidermis with destruction of the basal layer. The upper dermis has a bandlike (lichenoid) infiltrate of lymphocytes and histiocytes. The inflammatory reaction pattern is characteristic First appearing in the literature in 1977, lupus erythematous lichen planus (LE-LP) overlap syndrome was initially described by Romero et al 1 as a histologic entity with the features of both diseases; however, they proposed the findings as unique variants of either lupus erythematosus or lichen planus.
