Widespread cutaneous metastases from acinic cell carcinoma 20 years after primary presentation.

Acinic cell carcinoma is a rare, low-grade malignant salivary gland neoplasm. Approximately, 20% of patients experience local recurrence and 10% distant metastasis, often many years after initial presentation. We present a case of widespread cutaneous metastasis from acinic cell carcinoma arising in a 59-year-old woman with a history of acinic cell carcinoma of the parotid gland 20 years prior to her cutaneous disease.

Expression of androgen receptor by fibroepithelioma of Pinkus: evidence supporting classification as a basal cell carcinoma variant?

The classification of fibroepithelioma of Pinkus as basal cell carcinoma or trichoblastoma remains controversial. Immunohistochemical stains for androgen receptor may be useful in differentiating basal cell carcinoma from trichoepithelioma or trichoblastoma. We studied androgen receptor expression in 13 fibroepitheliomas of Pinkus, 11 basal cell carcinomas, 12 trichoepitheliomas, and 3 trichoblastomas.

Glutaraldehyde-induced and formaldehyde-induced allergic contact dermatitis among dental hygienists and assistants.

Background: Research has found that among health care workers, dental personnel are especially likely to have reactions to glutaraldehyde and formaldehyde.

Methods: The authors conducted patch test evaluations with a voluntary cohort of randomly recruited, healthy dental hygienists, or DHs, and dental assistants, or DAs, and nondental professionals to determine the incidence of glutaraldehyde-induced and formaldehyde-induced allergic contact dermatitis, or ACD; the potential for coreactivity between glutaraldehyde and formaldehyde; and the correlation between training methods in safe handling of sterilizing solutions and the sensitivity to glutaraldehyde and formaldehyde among DHs and DAs.

Results: The researchers enrolled 101 DHs and DAs and 51 nondental professionals in the study.
