Dermoscopic Findings in Intraepidermal Carcinoma: an Interobserver Agreement Study.

Introduction: A wide range of descriptive terms have been used for dermoscopic findings in intraepidermal carcinoma (IEC) and the clinical diagnostic accuracy of IEC can be challenging. Furthermore, dermoscopic findings in IEC have only rarely been evaluated in fair-skinned populations.

Objectives: To measure the interobserver agreement between dermatologists for dermoscopic findings in IEC.

Dermoscopic Evaluation of Inflammatory Nail Disorders and Their Mimics.

Nail dermoscopy (onychoscopy) is a valuable diagnostic tool for evaluating diseases in the nail apparatus. It is non-invasive, allowing clinicians to prioritize particular nails for biopsy. Thus, it can improve diagnostic accuracy and expedite treatment.

The impact of incomplete clinical information and initial biopsy technique on the histopathological diagnosis of cutaneous melanoma.

Background/objectives: Increased rates of histopathological misdiagnosis of melanoma have been associated with incisional punch more so than shave biopsy when compared with complete excisional biopsy. It is unknown how the increasing utilisation of shave biopsy may impact melanoma diagnosis. The extent to which the provision of clinical information to the pathologist may improve diagnostic accuracy remains unclear.

Methods of melanoma detection and of skin monitoring for individuals at high risk of melanoma: new Australian clinical practice.

Introduction: The evidence-based national clinical practice guidelines for the management of cutaneous melanoma published in 2008 are currently being updated. This article summarises the findings from multiple chapters of the guidelines on different methods of melanoma detection and of monitoring the skin for patients at high risk of melanoma. Early detection of melanoma is critical, as thinner tumours are associated with enhanced survival; therefore, strategies to improve early detection are important to reduce melanoma-related mortality.

Clinical practice guidelines for the diagnosis and management of melanoma: melanomas that lack classical clinical features.

A Cancer Council Australia multidisciplinary working group is currently revising and updating the 2008 evidence-based clinical practice guidelines for the management of cutaneous melanoma. While there have been many recent improvements in treatment options for metastatic melanoma, early diagnosis remains critical to reducing mortality from the disease. Improved awareness of the atypical presentations of this common malignancy is required to achieve this.

Subungual fibro-osseous pseudotumour of the toe.

Subungual fibro-osseous pseudotumour of the toe is a rare osseous soft tissue tumour of which only six cases have been described in the literature. We present a case in a teenage boy that posed an instructive diagnostic challenge and discuss the distinguishing features of the various differential diagnoses. The subungual location is very rare.

Efficacy of imiquimod cream, 5%, for lentigo maligna after complete excision: a study of 43 patients.

Objective: To determine the efficacy of imiquimod cream, 5%, in the treatment of lentigo maligna (LM).

Design: Open-label before-and-after interventional study.

Setting: A multidisciplinary melanoma clinic at a major tertiary hospital.

PlayStation purpura.

A 16-year-old boy presented with a number of asymptomatic pigmented macules on the volar aspect of his index fingers. Dermoscopy of each macule revealed a parallel ridge pattern of homogenous reddish-brown pigment. We propose that these lesions were induced by repetitive trauma from a Sony PlayStation 3 (Sony Corporation, Tokyo, Japan) vibration feedback controller.

Cutaneous melanoma--atypical variants and presentations.

Background: The incidence of melanoma continues to rise in Australia. General practitioners treat the majority of skin cancers affecting Australians. In the past decade, there has been improved uptake of dermoscopy by GPs who realise its value in the assessment of pigmented and nonpigmented lesions.

Dermatoscopy aids in the diagnosis of the solitary red scaly patch or plaque-features distinguishing superficial basal cell carcinoma, intraepidermal carcinoma, and psoriasis.

Background: Intraepidermal carcinoma (IEC), superficial basal cell carcinoma (sBCC), and psoriasis are common entities that may all present as well-defined, brightly erythematous plaques. Currently, there are limited data on the dermatoscopic features that differentiate these diagnoses.

Objective: We sought to describe the most significant morphologic findings seen on dermatoscopy of IEC, sBCC, and psoriasis, and formulate a diagnostic model based on these features.
