There is not an experimental model of localized cutaneous leishmaniasis (LCL) caused by Leishmania (Leishmania) mexicana. The aim of the present study was to characterize the clinical and histological features of Peromyscus yucatanicus experimentally infected with L. (L.) mexicana. A total of 54 P. yucatanicus (groups of 18) were inoculated with 1x10(6) promastigotes of L. (L.) mexicana in the ...
The monogenic autoinflammatory syndromes are conditions caused by mutations of genes coding for proteins that play a pivotal role in the regulation of the inflammatory response. Due to their genetic nature, most of these disorders have an early onset. Clinically they are characterised by recurrent flares of systemic inflammation presenting most of the time as sudden fever episodes associated ...
Cutaneous leishmaniasis (CL) is an endemic disease in the Republic of Panama, caused by Leishmania (Viannia) parasites, whose most common clinical manifestation is the presence of ulcerated lesions on the skin. These lesions usually present a chronic inflammatory reaction, sometimes granulomatous, with the presence of lymphocytes, plasma cells and macrophages. This study describes the histopath...

Clinical diagnosis usually requires seeing Leishmania bodies. Methods. We report two cases of cutaneous leishmaniasis with unusual histological finding of panniculitis. Case 1: a 36-year-old male presented with multiple u...
The development of cutaneous sarcoidosis as a paradoxical adverse event of tumor necrosis factor alpha (TNF-α) blockers has been reported in the literature; however, an erythrodermic form of cutaneous sarcoidosis during anti-TNF-α therapy has not yet been reported. Herein, we report the first case of an erythrodermic form of cutaneous sarcoidosis during anti-TNF-α therapy and review previous st...
Tattoo artists use many compounds to create tattoo pigment and several allergic reactions can occur as a result of these additives. The compositions of many inks have been identified; however, as new mixtures are created it becomes difficult to identify the specific ingredients in a particular ink. Allergic reactions to a particular pigment can manifest in several ways including allergic contac...
We report a case of metastatic Crohn's disease of the umbilicus which responded to topical corticosteroid treatment. Crohn's disease is a granulomatous disease of the bowel which may affect other organs. The skin is commonly involved, and the cutaneous manifestations may be non-specific, e.g. pyoderma gangrenosum or erythema nodosum, or specific with epithelioid granulomas and multinucleated gi...
