“…hypothesized that an intensive lichenoid reaction occurs quickly before the compensatory increased proliferation of keratinocytes develops as in typical lichen planus, due to which there is a rapid transformation of papules into brown macules. A similar transformation was noticed in two Korean patients . Also, coexistence of typical brown to violaceous patches in the right groin with minimally raised purplish scaly papules over the right iliac crest was reported .…”

Lichen planus pigmentosus-inversus is a rare variant of lichen planus. So far, only 24 cases from 12 reports have been documented in the published work. The prominent characteristics of the disease are dark-brown macules and patches confined to the non-sun exposed, flexural areas and skin folds with lichenoid pathological changes and prominent melanin incontinence. We report three female Chinese patients with typical clinical and pathological manifestations and a miniature review of the published work.

A 35-year-old man was referred to our hospital with a 3 months history of itchy cutaneous eruption on the trunk and asymptomatic cutaneous eruption on both groins. Physical examination revealed several, purplish-brown, scaly papules on the trunk and well-circumscribed, brown patchs in a linear distribution, on the bilateral inguinal regions. Dermoscopic examination of papules on the trunk revealed white crossing lines surrounded by brown dots; dermoscopic examination of patchs on groins revealed gray-brown dots and globules. According to histological, dermoscopical and clinical changes, the diagnoses of classical lichen planus (LP) for the lesions on the trunk; and lichen planus pigmentosus inversus (LPPI) for the lesions on the inguinal regions were made. Inhere we have described a rare case of LPPI and classical LP with dermoscopic features; and we suggest that LPPI is a variant of classical LP. Key words: Lichen planus; lichen planus pigmentosus inversus; dermoscopy CLASSICAL LICHEN PLANUS AND LICHEN PLANUS PIGMENTOSUS INVERSUS OVERLAP WITH DERMOSCOPIC FEATURES IntroductionLichen planus pigmentosus inversus (LPPI) presents with brownish macules and patches in flexural regions and known as a rare variant of lichen planus pigmentosus (LPP) [1]. LPP is an uncommon variant of chronic lichen planus (LP) that is characterized by hyperpigmented, dark-brown macules in sunexposed areas especially in Indian patients [2]. In here, we present a case of classical LP and LPPI overlap in a man, with dermoscopic features.

Lichen planus pigmentosus-inversus is a rare variant of lichen planus pigmentosus. The eruption of lichen planus pigmentosus-inversus occurs mainly in the flexural regions and presents with brownish macules and patches. Here we describe the case of a 31-year-old Korean woman who presented with hyperpigmented lesions over her antecubital and popliteal area and groin. Physical examination revealed multiple brownish macules and patches on the intertriginous area without pruritis, and histologic findings showed a regressive pattern of lichen planus. These clinical and histological findings were consistent with a diagnosis of lichen planus pigmentosus-inversus.
