TL;DR: This work describes two cases whose histologic features were conspicuous; numerous dissociated round cells that were arranged in linear arrays that resembled the histology of cancer en cuirasse to some extent, but the density and variety of tumor cell nests were much richer.

TL;DR: From the review of articles and experience, edible oils are useful agents for the first approach to remove asphalt from the point of view of efficacy, safety, availability and expense.

TL;DR: A 48-year-old Japanese woman with recurrent, disseminated papules on her legs that spontaneously regressed was diagnosed as having type A LyP mixed with type B, and the efficacy of bexarotene on LyP has been reported previously, but reported cases are still limited.

Abstract: Discussion LMDF is not an uncommon dermatosis among the Japanese, running a chronic course with spontaneous involution. The clinical course can be shortened by early treatment with a moderate dose of oral steroid [4] . Its clinical features are sometimes similar to cutaneous sarcoidosis, but the histopathological characteristics, epithelioid cell granulomas with or without caseation, are distinct. From its histopathological resemblance to tuberculosis, it was originally considered to be a variant of lupus vulgaris or a tuberculid. However, the evidence supporting its tuberculous etiology is largely circumstantial and not always convincing [5] . Currently, LMDF is widely regarded as a papular form of rosacea, which is supported by the observation that the granulomas found in LMDF appear in association with the pilosebaceous units, and by the fact that epithelioid granulomas have been found in some patients with rosacea [6] . On the other hand, the clinical features of LMDF are distinct from those of rosacea in several points [7, 8] . Particularly, its predilection sites are those not involved in rosacea, such as the eyelids and upper lip, in addition to its self-limited course leaving scars, which makes a sharp contrast with rosacea and suggests a different pathogenesis. To avoid confusion
