Dermoscopy in the Diagnostics of Incontinentia Pigmenti Skin Lesions.

Introduction: Incontinentia pigmenti (IP) is a rare X-linked geno-dermatosis characterized by numerous findings. Skin biopsy and histopathological analysis are considered as minor criteria for the diagnosis of IP. We assume that dermoscopy can assist the earlier diagnosis of IP.

Sensitivity and specificity of ex vivo dermatoscopy: a case series.

Background: Sensitivity and specificity of ex vivo dermatoscopy (EVD) for malignancy detection of skin tumors is unknown. We sought to assess whether the use of EVD could be a useful adjunct to histopathological diagnosis of pigmented skin tumors, including cases where complete clinical information is inadequate or missing.

Materials And Methods: EVD was performed on 195 excised, formalin-fixed pigmented skin tumors.

Predictors of sentinel lymph node status of cutaneous melanoma in Serbian patients.

Purpose: Presence of metastasis in sentinel lymph node (SLN) is considered to be the most important factor in terms of patient survival. The main aim of this study was to identify predictors of positive SLN in Serbian patients with melanoma.

Methods: This retrospective study was conducted on 147 patients.

Serum activity of DPPIV and its expression on lymphocytes in patients with melanoma and in people with vitiligo.

Background: Dipeptidyl peptidase IV, a multifunctional serine protease, is implicated in regulation of malignant transformation, promotion and further progression of cancer, exerting tumor-suppressing or even completely opposite - tumor-promoting activities. The aim of present research was to determine the serum DPPIV activity, as well as the percentages of CD26+ lymphocytes, CD26+ overall white blood cells and the mean fluorescence intensity of CD26 expression on lymphocytes in patients with melanoma, people with vitiligo and in healthy controls.

Methods: The activity of DPPIV in serum was determined by colorimetric test.

Immunity to melanin and to tyrosinase in melanoma patients, and in people with vitiligo.

Background: The aim of this study was to determine the presence and the intensity of humoral immunity to melanoma-associated antigens: tyrosinase and melanin, in patients with melanoma, in persons with vitiligo and in control healthy people.

Methods: The study involved 63 patients with melanoma and 19 persons with vitiligo. Control group consisted up to 41 healthy volunteers.

Molluscum contagiosum arising in melanocytic nevus and in superficial spreading melanoma.

Molluscum contagiosum (MC) is common skin infection caused by molluscum virus. Growth of MC inside melanocytic lesion is extremely rare. We present the case of MC in common melanocytic nevus and the first case of MC in superficial spreading malignant melanoma.

Male urethritis with and without discharge: relation to microbiological findings and polymorphonuclear counts.

Objective: We studied the relation between the presence or absence of urethral discharge, urethral pathogens, and polymorphonuclear (PMN) counts on Gram stained urethral smears in men with symptomatic urethritis.

Methods: The study population was composed of 630 sexually active heterosexual men (aged 18-45 years) who had urethral symptoms and signs (discharge, dysuria or urethral discomfort). Participants were divided into two groups: the first (n=320) was comprised of men with urethral discharge confirmed on examination, while the other (n=310) was composed of patients with urethral symptoms but without discharge.

[Ocular rosacea].

Five cases of ocular rosacea (one male and four females) are reported in this paper. Two of the patients were with keratoconjunctivitis sicca, one with conjunctivitis chronica and blepharitis, one with conjunctivitis chronica and meibomitis, and one with reccurent corneal erosions with meibomitis and chordeloum. In four patients ocular symptoms preceded the occurence of skin lesions.
