Hyperspectral Imaging for Non-invasive Diagnostics of Melanocytic Lesions.

Malignant melanoma poses a clinical diagnostic problem, since a large number of benign lesions are excised to find a single melanoma. This study assessed the accuracy of a novel non-invasive diagnostic technology, hyperspectral imaging, for melanoma detection. Lesions were imaged prior to excision and histopathological analysis.

[Diagnosis and treatment of actinic keratosis].

Actinic keratoses are premalignant skin lesions with the risk of converting into squamous cell carcinoma, and therefore they should be treated. Treatment modalities include cryotherapy, photodynamic therapy, carbon dioxide laser and also topical treatments such as imiquimode, ingenol mebutate, 5-fluorouracil and diclophenac. In the future, the treatment of actinic keratosis can be more often done in primary health care.

A Retrospective Study of Treatment of Squamous Cell Carcinoma In situ.

Squamous cell carcinoma in situ is an intra-epidermal malignancy of the skin with potential to progress to invasive carcinoma. Commonly used treatments are surgical excision, cryotherapy, photodynamic therapy, laser ablation, curettage with cautery, radiotherapy, topical 5-fluorouracil, and topical imiquimod. The efficacies of these different treatment modalities are compared in this retrospective study of 239 patients with squamous cell carcinoma in situ diagnosed and treated at our hospital during a period of one year.

[Treatment of hemangiomas].

Hemangioma is the most common benign tumor in infancy. Over 90% of hemangiomas require no treatment, but there is a need to recognize those that may require even quick measures to secure vital functions or normal development of organs. Propranolol has established itself as the first-line treatment.
