Amelanotic melanoma is a subtype of malignant melanoma that lacks clinically visible pigmentation. The absence of recognizable pigmentation obscures the clinical hallmark of the more typical form of malignant melanoma. Because it mimics various non-pigmented benign and malignant skin diseases, clinicians have difficulty diagnosing this lesion. An incorrect or delayed diagnosis can result in a worse outcome because the prognosis of melanoma depends on the tumor thickness and tissue invasion at the time of diagnosis. Therefore, early diagnosis is crucial for treating amelanotic melanoma. Dermoscopy is a useful non-invasive technique for diagnosing not only pigmented skin lesions, but also non-pigmented skin lesions because this modality can visualize vascular structures that are not discernible to the naked eye. Analyzing the dermoscopic vascular structures of amelanotic melanoma helps make an early diagnosis. We report here on a case of amelanotic melanoma for which the diagnosis was aided by performing dermoscopy as an adjuvant tool.

Tuberous sclerosis complex (TSC) is a neurocutaneous disorder with variable manifestations. The diagnosis is based on clinical criteria, and is divided into definite, probable, and possible TSC. If patients present with mild symptoms, clinicians may hesitate to perform further evaluations because of the high economic burden. A 16-year-old male presented with multiple skin-colored papules on the lower back and buttock. The histopathologic findings were compatible with connective tissue nevi (CTN). No other findings were observed with the exception of one hypomelanotic macule on the left shin. As the patient's parents wished to confirm the diagnosis, genetic testing was performed, and a TSC1 gene mutation was detected. With this genetic result, further evaluations were performed without hesitation. Genetic testing is a sensitive and specific modality for the diagnosis of TSC. We report a case of TSC presenting with CTN only, in which genetic testing was very useful to confirm the diagnosis and to determine the appropriateness of further high-cost studies.

LEOPARD syndrome is an autosomal dominant inherited disease with multiple congenital anomalies. LEOPARD is an acronym for Lentigines, Electrocardiographic conduction defects, Ocular hypertelorism, Pulmonary stenosis, Abnormalities of the genitalia, Retardation of growth, and Deafness. The disorder is caused by mutations in the PTPN11 gene or RAF1 gene. Here we report two typical cases of LEOPARD syndrome with lentigines, electrocardiograph abnormality, ocular hypertelorism which were proven to be the results of genetic mutations. Moreover, one 12-year-old boy showed growth retardation, deficiency in testosterone; the other 5-year-old girl had undergone implantation of a cochlear device and was diagnosed as having hypertrophic cardiomyopathy which has been managed with a beta blocker. Each patient showed a PTPN11 gene mutation: Thr468Met in exon 12 and Tyr279Cys in exon 7, respectively.
