Metastatic myoepithelial carcinoma in a child.

Cutaneous myoepithelial tumors are rare entities, with few reported malignant variants in the literature. The majority of these tumors are reported in the head and neck region of the adult population, with few examples in the literature arising in young patients. We present a case of myoepithelial carcinoma in a 13-year-old girl, with documented metastatic disease.

Multicentric parenchymal xanthogranuloma in a child: case report and review of the literature.

Objective And Importance: Xanthogranulomas of the central nervous system are rare, and asymptomatic lesions are often identified in autopsies. We report the first case of a multicentric, cystic, intraparenchymal xanthogranuloma, involving both the supra- and infratentorial compartments, in a 16-month-old girl.

Clinical Presentation: The clinical presentation consisted of a focal motor seizure in an otherwise healthy infant.

Should the diagnosis of benign prostatic hyperplasia be made on prostate needle biopsy?

Pathologists frequently sign out benign prostate needle biopsies as "benign prostatic hyperplasia (BPH)". There are no data indicating that a diagnosis of BPH on biopsy correlates with either gland weight or with the International Prostate Symptom Score (IPSS) used to measure urinary obstructive symptoms. We examined biopsies for average percentage of glands and average percentage of glands with papillary infolding per case, maximum percentage of glands and maximum percentage of glands with papillary infolding per core per case, and presence of any stromal nodules per case.
