Varicella-zoster virus (VZV) is a neurotropic virus which causes two distinct syndromes: primary infection presenting as varicella, mainly occurring in children without previous exposure to VZV, and reactivation of the latent VZV in the dorsal root ganglia, causing herpes zoster in adults. Herpes zoster clinically presents as a unilateral, painful, vesicular eruption, usually distributed to one or two adjacent thoracic dermatomes. As it is rarely seen confined to the upper limbs, few reports of herpes zoster involving the ulnar nerve exist in the literature, the majority describing patients who present with segmental zoster paresis of the upper extremity. This paper reports the case of a 73-year-old woman with ulnar and posterior antebrachial cutaneous nerve zoster reactivation and no history of immunosuppressive disorders. Therefore, rare occurrences of herpes zoster, such as the involvement of cervical dermatomes, should also be considered when faced with the differential diagnosis of symptomatic skin rashes of the upper limb, especially in elderly or immunosuppressed patients.

Basal cell carcinoma is a slow growing non-melanoma skin cancer appearing as a non-healing, painless, and sometimes pruriginous sore, usually on sun-exposed areas. Although it rarely metastasizes, BCC diagnosis and treatment should not be delayed due to its local invasive potential. Currently, dermatoscopy is a well propagated and commonly employed tool in clinical practice, providing a fast and handy approach to clinical diagnosis, without the significant financial costs associated with other more sophisticated diagnostic means. Since the very first dermatoscopic descriptions of basal cell carcinoma, the list of dermatoscopic diagnostic criteria has been updated and renewed numerous times. Dermatoscopy significantly augments basal cell carcinoma detection by its capability of discriminating it from other skin lesions and inflammatory skin conditions. Moreover, current evidence suggests that this noninvasive, real-time imaging technique is also valuable in tumor management, seeing that it provides additional information related to histopathological subtype, presence or lack of pigmentation, lateral tumor extension, and tumor response to non-surgical treatments. In this paper, we aim to summarize time-honored as well as current knowledge on the value of dermatoscopy in the diagnosis, classification, and treatment of basal cell carcinoma.

Skin and soft tissue infections are a frequent reason to address the dermatologist's office. Their evolution depends both on the patients' comorbidities and on the pathogenicity of the infecting microorganism. The antibiotic therapy is the core of the treatment. Its success is the result of the co-operation between clinician and microbiologist. Well tailored initial therapy, guided by local flora and the Gram smear data may enhance success and reduce complications. [ABSTRACT FROM AUTHOR]
