A 13-year-old boy presented congenital, raised, yellowish colored plaques with fibroelastic consistency, which were velvety in appearance, alopecic, with clearly defined limits and sulci or well-marked meandering invaginations, a cerebriform appearance on the upper part of the right ear, accompanied by alopecia in the temporomandibular region-parietal. The lesion was asymptomatic. Histopatholog...

Although nevus sebaceous (NS) is known to develop various types of secondary neoplasms, it rarely causes carcinoma and only fifteen cases of secondary squamous cell carcinoma (SCC) have been reported. We report a rare variant of SCC (acantholytic type) arising in nevus sebaceus.

Focal thickening of the calvarium, hypoplasia of the white matter, cortical calcifications, and a leptomeningeal drape that enhanced after contrast injection were demonstrated by MR in the parietooccipital region ipsilateral to a facial sebaceous nevus in a patient with epidermal nevus syndrome.

BACKGROUND Recent studies have demonstrated telomerase expression in ophthalmologic sebaceous carcinoma and have suggested possible diagnostic utility in distinguishing these neoplasms from sebaceous adenomas. The aim of this study was to evaluate telomerase expression via human telomerase reverse transcriptase (hTERT) immunohistochemical staining in a spectrum of sebaceous lesions of the skin....

BACKGROUND The epidermal nevus syndromes include different diseases that have the common feature of mosaicism. One of these has been recently identified and named phacomatosis pigmentokeratotica, in analogy to phacomatosis pigmentovascularis. It is characterized by an organoid nevus with sebaceous differentiation, a speckled-lentiginous nevus, and other associated anomalies. It has been hypothe...

An 11-year-old boy presented with raised pigmented lesion over the scalp since 10 years. Parents gave history of hairless yellowish plaque present over the scalp at birth which gradually increased to present size to take cerebriform appearance. There was no history of trauma. All routine hematological investigations were normal. No systemic and developmental defect was noted. X-ray skull, eye a...
