Linear distribution of multiple subcutaneous nodules or ulcers along the course of lymphatics, classically seen in lymphocutaneous sporotrichosis, has been observed in a number of other infections like localized cutaneous leishmaniasis, cutaneous tuberculous and non tuberculous mycobacterial infections, Pasteurella tularensis, Scopulariopsis blochi, Nocardia brasiliensis, yaws and syphilis. A c...

Pancreatic cancer is one of the most dangerous human cancers and will continue to be a major unsolved health problem as we enter the 21(st) century. This is the case despite advances in imaging technology and surgical management. Indeed, 80% to 90% of pancreatic cancers are diagnosed either at the locally advanced or metastatic stage. Cutaneous metastases originating from pancreatic cancer are ...

Cutaneous lymphomas (CL) are the second most common extranodal non-Hodgkin’s lymphomas. Their incidence is estimated at 1/100 000 yearly. Primary CL develop by definition in the skin and remain confined to the skin for a long period of time, while secondary CL reflect cutaneous spread from disseminated primary nodal or extranodal lymphomas. Primary CL include a wide spectrum of clinically and h...

background: cutaneous leishmaniasis is an endemic disease in many regions of iran, including the city of mashhad. in recent years, some cases have not responded to glucantime, the usual treatment for this disease. the cellular immune response caused by t-helper type 1 (th1) cells has an important role in protection against leishmaniasis, and activation of the t-helper type 2 (th2) response caus...

Cutaneous diseases can indicate the presence of hepatitis C virus (HCV) infection. The aim of this study was to analyse the frequency of cutaneous findings in HCV infection and HCV RNA positive cases in Turkey. Fifty consecutive patients positive for anti-HCV antibodies,negative controls, and patients positive and negative for HCV RNA were examined for any cutaneous findings that could be assoc...

background: cutaneous leishmaniasis is a neglected parasitic disease, which imposes massive human distress and financial costs to the endemic countries. better understanding of host immune response to the parasite leads to helpful strategies for disease control. interleukin (il)-10 and transforming growth factor (tgf)-β are important immune regulatory cytokines, which appear to develop non-heal...

Sarcoidosis is an idiopathic multisystemic disorder with variable cutaneous presentations that are classified as specific or non-specific according to the presence of non-caseating granulomas on histologic examination. Specific manifestations can include papules, scar sarcoidosis, ulcers, or even alopecia. Herein, we present a case of cutaneous sarcoidosis that presented as multiple erythematou...

Sarcoidosis is an antigen-mediated disease of unknown aetiology, characterized by the presence of non-caseating epithelioid cell granulomas in multiple organs. Cutaneous involvement in sarcoidosis is classified as specific, when biopsy reveals non-caseating granulomas, and non-specific, typically erythema nodosum. Granulomatous skin lesions occur in 9% to 37% of patients. The skin is the second...

BACKGROUND Malignant melanoma arising from different body compartments may be associated with differing aetiological factors and clinical behaviour, and may manifest diverse molecular genetic profiles. Although many studies have focused on cutaneous melanoma, little is known of mucosal and other types of melanoma. In particular, malignant melanoma of soft parts is different from other melanomas...

The presence of a large right-to-left shunt is associated with neurological decompression illness after non-provocative dives, as a result of paradoxical gas embolism. A small number of observations suggest that cutaneous decompression illness is also associated with a right-to-left shunt, although an embolic aetiology of a diffuse rash is more difficult to explain. We performed a retrospective...
