Aim: The original article aimed to evaluate the diagnostic accuracy of clinical and dermoscopic image tele-evaluation for mobile skin tumor screening.
Setting and population: The tumors examined in the study were selected prospectively from an outpatient clinic in Graz, Austria in a duration of 3 months. They are from men or women with benign and/or malignant skin tumors of either melanocytic or non-melanocytic origin. A total of 104 tumors from 80 patients using a mobile phone camera were gathered. The lesions were from the head and neck area, trunk, legs and feet and genital area.
Study examination: A board-certified dermatologist with clinical expertise in teledermatology and dermoscopy reviewed the clinical and dermoscopic pictures with clinical information separately. The results from the review of the pictures were compared with those obtained by face-to-face examination and the gold standard face-to-face examination plus histopathology.
Outcome: Tumors were classified under four categories: benign non-melanocytic, benign melanocytic, malignant non-melanocytic and malignant melanocytic. The table (Table 1) below shows the final diagnoses of the skin tumors examined per category.
Results: Among these 104 lesions, 25 (24%) benign non-melanocytic, 15 (14%) benign melanocytic, 58 (56%) malignant non-melanocytic and six (6%) malignant melanocytic lesions were identified. Clinical and dermoscopic tele-evaluations showed high sensitivity and specificity. For malignant non-melanocytic tumors, sensitivity for both clinical and dermoscopic lesions is 97%; specificity for clinical and dermoscopic lesions are 91& and 94%, respectively. For classifying malignant melanocytic lesions, sensitivity for both clinical and dermoscopic lesions is 100% while specificity is 98% and 97%, respectively
Conclusion: Clinical image tele-evaluation might be the method of choice for mobile tumor screening. Both clinical image tele-evaluation and teledermoscopy achieved excellent and equally high concordance rates with the gold standard.

Primary Cutaneous Anaplastic Large Cell Lymphoma (PC-ALCL) is a rare Non-Hodgkin lymphoma (NHL) representing approximately 9% of all cutaneous lymphomas.3 It usually manifests as a slow-growing, solitary tumor which has a tendency to regress spontaneously. However, metastasis is reported in 5-10% of cases.
