Chronic recurrent annular neutrophilic dermatosis: A rare entity.

We report a new case of chronic recurrent annular neutrophilic dermatosis in a woman. Through our observation, we aim to make the clinician aware of this rare entity, in order to consider it among the diagnostic hypotheses of annular dermatosis, with centrifugal, recurrent, and chronic evolution.

Annular elastolytic giant cell granuloma mimicking cutaneous sarcoidosis.

Annular elastolytic giant cell granuloma (AEGCG) is a benign skin disorder, with, unknown cause. It appears as erythematous papules or annular plaques. Few challenging cases of AEGCG have been reported in the literature. We describe a rare clinical presentation of AEGCG mimicking cutaneous sarcoidosis.

Lichen amyloidosis successfully treated with fractional ablative laser CO2: A new alternative therapeutic.

Lichen amyloidosis is a primary localized cutaneous amyloidosis. Different types of treatment have been used without complete resolution. Herein, we report a case of patient suffering from lichen amyloidosis successfully treated with fractional ablative laser CO2. He was a 59-year-old man diagnosed lichen amyloidosis localized on the legs 10 years ago. He was treated with topical corticosteroids without any improvement. Then, we started treating the affected area with CO2 laser (limmer*) at a setting of 5-8 J/cm2 and 8 mm laser spot size. A considerable improvement was noticed after the first session. A total healing was reported after four sessions. To the best of our knowledge, only 11 reported cases of lichen amyloidosis have been successfully treated with laser CO2. However, our clinical finding seems to be one of the best reported results.

Lichen planus pigmentosus inversus: a series of 10 Tunisian patients.

BACKGROUND: Lichen planus pigmentosus inversus (LPPI) is a rare variant of LP. Only 31 cases have been reported in the literature. METHODS: Here we report a series of 10 patients with LPPI from North Africa. RESULTS: Ten cases of LPPI, clinically suspected and histologically confirmed, were seen over 3 years (2013-2015). The mean age of patients was 62.4 years old. Eight patients were women and two were men. Main folds involved were the axillae and groin. All patients were treated by topical steroids without success. CONCLUSIONS: Our series of LPPI seems that this disorder is underreported mainly among 3 dark-skinned persons as we have seen these ten cases within three years.

Ecthyma Gangrenosum Caused by Escherichia coli in a Previously Healthy Girl.

Ecthyma gangrenosum is a characteristic lesion of Pseudomonas aeruginosa sepsis in immunocompromised patients. Only eight cases of ecthyma gangrenosum caused by Escherichia coli have been reported. We report a case of ecthyma gangrenosum due to E. coli without bacteremia in a previously healthy girl.

Baboon syndrome induced by hydroxyzine.

Hydroxyzine-induced drug eruptions are very rare. We report here a typical case of drug-related Baboon syndrome or symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) which was induced by hydroxyzine in a 60-year-old man. The diagnosis was confirmed by positive patch and oral accidental provocation tests with hydroxyzine. Patch tests and oral provocation tests with cetirizine and levocetirizine were negative. A review of the literature identified only 17 reported cases of hydroxyzine-induced drug eruptions. To the best of our knowledge, we report here the first case of hydroxyzine-induced SDRIFE.

Bullous allergic contact dermatitis to pure henna in a 3-year-old girl.

Natural henna is known to have a very low allergic potential. We describe here an exceptional case of bullous contact dermatitis caused by pure henna.
