Metastasizing pleomorphic adenoma: a fascinating enigma.

Among salivary gland neoplasms, metastasizing pleomorphic adenoma (MPA) constitutes an extremely rare group of tumors. The present paper reports a case of pleomorphic adenoma (PA) in submandibular gland that, after more than 30 years of initial treatment, recurred and metastasized to ipsilateral neck lymph nodes and parotid gland. In an attempt to elucidate the malignant behavior of metastasizing pleomorphic adenoma, we performed Ki-67, p53, p16, and bcl-2 immunohistochemistry staining of our case sample.

Radiographical vignette: an apical lung density in an elderly man with hemoptysis.

An Aspergilloma is a "ball" of fungal mycelia composed of Aspergillus species developing in a pre-existing lung cavity. This uncommon entity may cause hemoptysis and may be a diagnostic challenge. We present imaging and review the literature of a recent case managed in our institution.

Epidemiological characterization of pediatric patients with status asthmaticus admitted to intensive care units.

Asthma morbidity and mortality have increased in the past two decades; Puerto Rican children have the highest prevalence of asthma in the United States. An asthma admission to PICU is a marker of asthma severity. This study describes the profile of the pediatric population admitted with status asthmaticus during a three year period to PICU at Hospital Episcopal San Lucas.
