Transporter associated with antigen processing deficiency syndrome: case report of an adolescent with chronic perforated granulomatous skin lesions due to TAP2 mutation.

A previously unreported case of transporter associated with antigen processing (TAP) deficiency syndrome (with no parental consanguinity) due to a homozygous TAP2 mutation is presented. Characteristic nonhealing, chronic, ulcerative granulomatous leg lesions combined with recurrent otitis media and sinopulmonary infections led to this boy being diagnosed at 15 years old. The role of the dermatologist was crucial in making the correct diagnosis and thereby positively influencing the quality of life and life expectancy of this boy.

Development of a three-dimensional surface imaging system for melanocytic skin lesion evaluation.

Even though surface morphology is always taken into account when assessing clinically pigmented skin lesions, it is not captured by most modern imaging systems using digital imaging. Our aim is to develop a novel three-dimensional (3D) imaging technique to record detailed information of the surface anatomy of melanocytic lesions that will enable improved classification through digital imaging. The apparatus consists of three high-resolution cameras, a light source, and accompanying software.

Prehistological evaluation of benign and malignant pigmented skin lesions with optical computed tomography.

Discrimination of benign and malignant melanocytic lesions is a major issue in clinical dermatology. Assessment of the thickness of melanoma is critical for prognosis and treatment selection. We aimed to evaluate a novel optical computed tomography (optical-CT) system as a tool for three-dimensional (3-D) imaging of melanocytic lesions and its ability to discriminate benign from malignant melanocytic lesions while simultaneously determining the thickness of invasive melanoma.

Factors associated with the prevalence of atypical nevus in a Mediterranean pigmented skin lesion clinic.

Atypical melanocytic nevi constitute central risk factor and are precursor lesions for cutaneous melanoma. Data regarding factors associated with their prevalence are mainly derived from fair-skinned populations, whereas little is known regarding their epidemiological associations in darker-skinned, chronically sun-exposed populations. The aim of this study was to identify risk factors for the occurrence of at least one atypical nevus on Crete, the southernmost island of Greece.
