BACKGROUND Endothelial damage and activation may play central roles in the pathogenesis of systemic sclerosis (SSc) and are reflected by microparticles (MPs) and soluble selectins. The objective of this study was to determine if these potential biomarkers are associated with specific organ involvements or cutaneous subgroups of SSc patients. METHOD MPs in platelet-poor plasma from 121 patient...

BACKGROUND In this study the level of IL-23 and IL-27 produced by macrophages derived from peripheral blood mononuclear cell culture collected from patients with healing or non-healing form of cutaneous leishmaniasis lesion were compared before and after treatment with live Leishmania to explore whether IL-23 or IL-27 plays any role in healing process of cutaneous lesions induced by L. major. ...

Background and Objective: Cutaneous cytology is the study of scraping or smears obtained from skin lesions. Although not commonly employed, cutaneous cytology has been a useful tool for clinicians due to simplified procedures and high sensitivity and specificity of presurgical clinical diagnosis of commo...

To the Editor, Basal cell carcinoma (BCC) is one of the most common cutaneous malignancies. Although it constitutes 75% of non-melanoma cutaneous malignancies, it develops in the perianal region in less than 1% of cases (1,2). Even though histopathologic findings of BCC developing in the perianal region are similar to those of BCC seen in other regions, perianal cancers behave much more aggress...

Cytology of cutaneous and subcutaneous masses represents an opportunity to screen potential surgical cases and determine an etiologic agent or rule out potential neoplasia. This session will focus on common non-neoplastic and neoplastic tumors that present to practitioners. Helpful hints are given how to best diagnose the conditions. Cytodiagnostic groups for cutaneous and subcutaneous tissues ...

Infection with the human immunodeficiency virus (HIV) leads to a chronic disarmament of the immune system. The process is progressive, having different manifestations as the status of the immune system slowly deteriorates. Some of the most common manifestations of HIV infection are cutaneous in origin, and they can have infectious, neoplastic, or noninfectious or non-neoplastic etiologies. A br...

Lymphoepithelioma-like carcinoma of the skin (LELCS) is a rare cutaneous neoplasm with microscopic similarities to non-cutaneous lymphoepitheliomatous malignancies, particularly undifferentiated carcinoma of the nasopharynx. It can be clinically and histologically confused with other benign and malignant tumors. If not adequately treated, recurrence and distant metastasis are probable. We prese...

One of the possible systemic complications of gonorrhoea is disseminated gonococcal infection (DGI), which is usually characterised by both skin and joint lesions. While joint involvement ranges from tenosynovitis to suppurative arthritis, cutaneous involvement features varied non-specific patterns often clinically and histologically consistent with vasculitis. We report a case of DGI in which ...

Nodular cutaneous amyloidosis (NCA), the least common form of primary cutaneous amyloidosis, is characterized clinically by waxy, purpuric plaques and nodules and histologically by amyloid deposits in the dermis and subcutaneous tissue. We present a patient who developed multiple, non-contiguous NCA lesions over a three year period without evidence of systemic disease. We reviewed the literatur...
