Lichen planus is an inflammatory disorder of the skin and/or mucosa. Immune dysregulation, infections, environmental and genetic factors play a role in its pathogenesis. Clinically, there are 6 important distinctive manifestations. The mucosal subtypes manifest inside the mouth, oesophagus, genitalia and - although less often - the nose, ear canal ...

Lichen sclerosus (LS) is an inflammatory skin disease predominantly affecting the anogenital region. If untreated, progressive sclerosis results in scarring with distortion of the normal architecture. LS occurs more commonly in women than men but may occur in all age groups, including adolescents and prepubertal children.

Lichen Scrofulosorum Mimicking Lichen Planus
The American Journal of Dermatopathology, 2011Lichen scrofulosorum is the most uncommon clinicopathologic variant of the tuberculids. Usually, the eruption appears in children and adolescents with strong immune sensitivity to Mycobacterium tuberculosis and consists of tiny follicular papules, closely resembling lichen nitidus.

FOLLICULAR LICHEN PLANUS (LICHEN PLANOPILARIS)
Archives of Dermatology, 1953IN THIS study we have directed our effort toward clarification of a syndrome most appropriately termed follicular lichen planus, which has been the subject of considerable discussion since the turn of the century. The British and American authors who kept the discussion alive have progressively contributed to the better understanding of the disease. In

Lichen planopilaris is a chronic scarring alopecia characterized by follicular hyperkeratosis, perifollicular erythema, and loss of follicular orifices. The scalp lesions may be single or multiple and commonly involve the vertex and parietal area. The hair follicles at the margin of the alopecic patches reveal perifollicular erythema.

P, a 20‐year‐old laborer displayed initial symptoms of the disease in question when he was 10 years old. Initially he had an asymptomatic progressive loss of hair on the scalp. A couple of years later he had mild to moderate pruritis, and the appearance of slate‐blue eruptions on the scalp and elsewhere on the body.

Lichen aureus is one of the rarest of the pigmented and purpuric dermatoses. The eruption consists of lichenoid papules and plaques with a golden to purplish color, and the histology reveals a dense and bandlike infiltrate hugging the epidermis. It consists of lymphocytes and histiocytes, often with extravasation of red cells.

ABSTRACT: The possible relationship between lichen striatus and atopy was studied. Twenty‐six patients with typical lichen striatus were studied, and 22 (84.6%) had a positive history of atopic disorders. This might indicate that the pathogenesis of lichen striatus has a close relationship to that of atopic disorders.

Abstract: A 12‐month‐old boy with pulmonary tuberculosis developed a papular lichenoid eruption which showed epithelioid granulomas on histology, consistent with lichen scrofulosorum. Stains and cultures for mycobacteria in the skin were negative, and a polymerase chain reaction (PCR) analysis failed to detect the DNA of Mycobacterium tuberculosis in a
