RESUMEN
Introduction: Spitz nevus is an uncommon, benign melanocytic proliferation that primarily appears on face, trunk or lower extremities of children. This lesion may share clinical and microscopical characteristics with melanoma, making it a diagnostic and management challenge. Case Report: A 13-year old male presented with an asymptomatic chronic dermatosis located on the third left-hand nail. Cutaneous examination revealed a homogeneous dark brown melanonychia which extended up to the cuticle. Upon dermoscopy, longitudinal bands measuring less than 3 mm wide of heterogeneous colors ranging from light to dark brown, and positive Hutchinson's sign were observed. Discussion/Conclusion: We report the second case of a Spitz nevus ungually localized which strongly resembled an ungual melanoma with a positive Hutchinson's sign upon dermoscopy. Describing the infrequent presentation and location of the Spitz nevus poses an opportunity to establish diagnostic and management criteria in the near future.
RESUMEN
Scleromyxedema is an uncommon and progressive fibromucinous disorder characterized by disseminated papular eruption with histological features of dermal mucin deposition. The skin changes associated with this disease are highly visible and they tend to affect the patient's quality of life. We report a case of a 50-year-old male patient that presented a 3-year-old history of disseminated asymptomatic firm papules-associated systemic symptoms. Medical treatment with oral corticosteroid and thalidomide was indicated and surgical treatment on residual facial folds was performed, with an excellent outcome.
RESUMEN
BACKGROUND: Onychocryptosis is one of the most common painful nail conditions. Conservative treatment may take a long time to obtain effective results. OBJECTIVE: The purpose of this study is to show the effectiveness of a conservative treatment of ingrown nails that shows rapid results. METHODS AND MATERIALS: Patients with painful Stage 1 to 2 onychocryptosis who were not candidates or refused surgery were treated with the cotton cast. The severity and cause of onychocryptosis was clinically evaluated during a 2-month period. A questionnaire was applied to all patients to evaluate pain, final treatment, and possible complications. RESULTS: All patients noticed results in less than 72 hours. Pain subsided in less than 24 hours in half of the patients and before 72 hours in 100% of the patients without the need of other treatments. The use of the cast prevented surgery and the accompanying morbidities in most of the patients (80%). CONCLUSION: The "cotton nail cast" is an effective conservative method for mild nail embedding. It is easy to apply, inexpensive, relieves pain rapidly, and avoids surgery in most patients.
