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...

The use of the nasocheek sulcus flap with a cartilage strut provides an aesthetically pleasing result in total columella reconstruction. This provides thin hairless skin appropriate for the subunit. Mohs surgery aids in limiting the excision to the tumor involved area, providing a complete clearance and conserving precious units, which have an impact on the reconstructive options. The method of...

SUMMARY A single 200-j.ig dose of tritiated 7,12-dimethylbenz(a)-anthracene containing 18 j.iCi tritium was applied to the skin of female hairless mice. Biopsies were taken at intervals from 30 mm to 72 hr after application of the carcinogen and processed for autoradiography. All specimens showed labeling of many, but not all, dermal mast cells. The label was also found in the epidermis, hair f...

Glandular trichomes are remarkable biochemical factories that produce a wealth of secondary metabolites important for plant defenses against herbivores. However, little is known about their developmental biology. Studying the tomato hairless mutant, which develops distorted glandular trichomes and has compromised metabolic and defense capacity, Kang et al. (pages 5313–5324 in this issue) showed...

Eccrine poroma is a benign neoplasm thought to originate from the eccrine sweat glands. The majority of eccrine poroma occur on the hairless acral surface, and cases of eccrine poroma on the scalp are rare. Moreover, all these case reports describe only the histopathological, not radiological, features of eccrine poroma. Here, we first report the magnetic resonance (MR) findings in a rare case ...
