Confluent and reticulated papillomatosis (Gougerot and Carteaud) is a rare but clinically distinct dermatosis of which the etiology is unknown. We report 2 cases. One case is a 16-year-old boy who had a hyperpigmented reticulated eruption on the trunk and both arms and the other case is a 33-year-old man who had a similar eruption on the chest and back. The former, with previous treatment with oral and topical antifungal agent in another clinic didn't show any improvement and the latter case, with initial treatment of itraconazole did not improve his skin lesion. The rashes of two patients virtually disappeared with administration of minocycline. These observations indicate that the role of microorganisms sensitive to minocycline or anti- proliferative effect of minocycline could be presumed.

Chilblain lupus erythematsus is a rare special subtype of chronic cutaneous lupus erythematosus characterized erythematous acral skin lesion induced by cold, damp climate. Approximately, only 20% of the patients presenting with chilblain lupus erythematosus later develop systemic lupus erythematosus(SLE). We present here a case of chilblain lupus erythematosus, associated with a development of SLE later. A 29-year-old female patient has had violaceous and erythematous papules on the ear, dorsal hands and finger tips for 10 years and these lesions have been aggravated by winter. She has been diagnosed as a suspicious SLE for 3 years and then was treated with oral prednisolone and hydroxychloroqine.
