Pesticide-associated pemphigus vulgaris.

We present a 40-year-old man with occupation-induced pemphigus vulgaris (PV). He developed PV within days of a one-time heavy exposure to fumes of burning glyphosate, a broad-spectrum nonselective pesticide. This exposure suggests acute cutaneous contact as a stimulus in the development of his pemphigus.

The role of topical immune response modifiers in skin cancer.

Topical immune response modifiers include imiquimod and resiquimod. The mechanism of action of immune response modifiers is complex and not completely understood. It involves the stimulation of innate and cell-mediated immune responses through Toll-like receptor-mediated induction of cytokines.

Her-2 expression in cutaneous eccrine and apocrine neoplasms.

Cutaneous eccrine and apocrine glands have many histologic and immunologic similarities to ducts and acini of the breast. Thus, differentiating a primary cutaneous process from a metastatic breast carcinoma can be nearly impossible. In all, 10-34% of breast carcinomas overexpress HER-2 protein, a membrane-associated protein that functions in cell differentiation, adhesion and motility.

Localized epidermolytic hyperkeratosis of the female external genitalia.

Background: Epidermolytic hyperkeratosis (EH) is most commonly associated with the diffuse involvement of congenital ichthyosiform erythroderma, but can also be found in a localized pattern. Localized EH is rare, but mucocutaneous lesions have been been identified, most commonly in the mouth.

Methods: We observed a 58-year-old African-American female who noted spots on her genitalia for approximately 2 years.
