The colors that are seen in dermoscopy depend on the anatomic level of the skin at which the chromophores are seen. Blue color can be found in a variety of melanocytic and nonmelanocytic lesions. An 89-year-old man presented with a 3-year history of a slow-growing, hyperpigmented patch located on the distal third of the right arm. Dermoscopy showed an atypical network, irregularly distributed g...

A 15-month-old girl presented with developmental delay, intractable right focal motor seizures, hyperpigmented patch on the left side of the face, facial asymmetry, and right hemiparesis (figure 1). A diagnosis of linear nevus sebaceous syndrome (LNSS) was considered. Brain MRI revealed hemimegalencephaly (figure 2). EEG showed spike/wave discharges in left occipital leads. Ophthalmologic and s...

Sir, Becker's naevus or Becker's melanosis is a relatively common disorder, which appears as a hyperpigmented, hypertrichotic patch located mainly on the trunk (1). Becker's naevus has been associated with various soft tissue and bony structural anomalies, such as hypoplasia of the ipsilateral breast, pectoralis major muscle, leg, arm and contralateral breast, spina bi®da, and pectus carinatum ...

Dear Editor, Becker’s nevus is a relatively common, hyperpigmented patch, frequently associated with hypertrichosis.1 Males are more commonly affected than females, with an incidence of around 0.25%.2 Becker’s nevus may be associated with various cutaneous and skeletal anomalies. However, basal cell carcinoma (BCC) is a slow-growing; locally invasive tumour arising from pluripotent stem cells w...

A 33-year-old woman with no underlying systemic disease visited our hospital with a tender, hyperpigmented skin tumor over the right lateral chest wall for 6 months. Initially, the lesion was a small hemorrhagic cutaneous papule. Perifocal hyperpigmentation developed progressively and the lesion gradually enlarged to 2 cm at its greatest diameter. On physical examination, a painful illdefined m...

amyloidosis cutis dyschromica (acd) is a rare form of macular amyloidosis characterized by hypo and hyperpigmented macules. here we described a 20 year old girl with diffuse hypo and hyperpigmentation since she was four years old. five other members of her family are also involved. biopsy of hyperpigmented lesions revealed increase of melanin in the basal layer, pigment incontinence and amorpho...
