Background: Nail unit melanoma (NUM) is a rare variant of acral lentiginous melanoma. The differential diagnosis is wide but an acquired brown streak in the nail of a fair-skinned person must be considered a potential melanoma. Dermatoscopy helps clinicians to more accurately decide if a nail apparatus biopsy is necessary. Methods: We report the case of a 61-year-old Caucasian woman with melanonychia occupying the central portion of the right thumbnail plate with 1 year of evolution. Dermatoscopy showed a brown pigmentation overlaid by longitudinal irregular lines. An excisional biopsy was performed, and pathological examination revealed melanoma in situ. For safety reasons, the nail unit was totally removed down to the phalangeal bone 3 weeks later, and a full-thickness skin graft taken from the arm was used for reconstruction. Conclusion: NUMs pose a difficult treatment challenge. Wide excision with phalanx amputation is not satisfactory for patients with in situ and early invasive melanoma. Full-thickness skin grafting after total nail unit excision is a simple procedure providing a good functional and cosmetic outcome.

The scientific literature on GLLR is vast, however controlled and randomized studies comparing different surgical techniques are lacking. At the present moment it is not clear if bioengineered materials are superior to conventional autogeneous tissue as lower eyelid spacers. The effects of GLLR on lower eyelid movements and contour have not been studied.

Background: Eccrine hidrocystomas are rarely described benign cystic lesions, mainly presenting in middle-aged women in the centrofacial area and usually associated with a chronic course, seasonal variability and no proved and consistently efficacious treatments. Case Report: We report 2 patients, a 45- and a 56-year-old woman, with multiple facial eccrine hidrocystomas suggested by dermatoscopy, confirmed by histology and treated with botulinum toxin A with excellent results. Conclusion: Our report stresses the role of dermatoscopy in the diagnosis and follow-up of these lesions, as well as the impact of repeated treatments with botulinum toxin A in eccrine hidrocystomas suggesting it as a first-line treatment for multiple eccrine hidrocystomas because it is easy to use and has no risk of scars.

Diffusion-weighted imaging (DWI) is widely used in protocols for magnetic resonance imaging (MRI) of the female pelvis. It provides functional and structural information about biological tissues, without the use of ionizing radiation or intravenous administration of contrast medium. High signal intensity on DWI with simultaneous low signal intensity on apparent diffusion coefficient maps is usually associated with malignancy. However, that pattern can also be seen in many benign lesions, a fact that should be recognized by radiologists. Correlating DWI findings with those of conventional (T1- and T2-weighted) MRI sequences and those of contrast-enhanced MRI sequences is mandatory in order to avoid potential pitfalls. The aim of this review article is the description of the most relevant physiological and benign pathological conditions of the female pelvis that can show restricted diffusion on DWI.

Unilateral laterothoracic exanthem is a self-limited disease that occurs most commonly in children. It is characterized by unilateral exanthem, often in axillary region. The etiology is unknown, but a viral agent is suspected. We report a 1-year-old white girl with unilateral laterothoracic exanthem associated with Epstein Barr virus infection, suggesting this virus has a possible etiologic role.

An obturator hernia is a rare condition and an unusual cause of intestinal obstruction. With a challenging diagnosis, it has one of the highest mortality rates of all abdominal wall hernias. The authors present a case of an elderly woman with bowel obstruction secondary to an incarcerated obturator hernia. An 80-year-old woman presented at the emergency room with complaints for the last 2 days of nausea, vomiting, constipation and lower right abdominal pain that radiated down to the right medial thigh. Abdominal tenderness to deep palpation of the right iliac fossa and mildly distention were noted. A CT scan demonstrated bowel obstruction secondary to an incarcerated obturator hernia. The patient underwent emergency exploratory laparotomy. The incarcerated bowel was reduced and the defect was repaired with a plug of polypropylene mesh covered with peritoneum. The patient had an uneventful postoperative period and was discharged on the fifth postoperative day.
