Abstract:
We present a 58-year-old Jamaican man with an eight-month history of an isolated, vegetative, eroded, and crusted plaque on the posterior aspect of the scalp. One month prior to referral to the Charles C. Harris Skin and Cancer Pavilion he developed a few, scattered erosions on the extremities. A biopsy specimen showed suprabasal acantholysis along with deposition of C3 and IgG on a direct immunofluorescence test. Localized pemphigus is a rare variant of pemphigus vulgaris. Localized pemphigus presents with a localized plaque that remains localized for an extended period of time without generalized bullae formation. Our patient represents an unusual case of localized pemphigus of the scalp with vegetative features.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
