Fellowship training in pediatric pathology: a guide for program directors.

ABSTRACT The Accreditation Council for Graduate Medical Education (ACGME) has provided guidance for specialty and subspecialty fellowship training programs by defining 6 core competencies that must be met. Furthermore, the ACGME has defined several program requirements for pathology training, including those applicable to several pathology subspecialties. However, the requirements are broad and lack specific details, particularly as they pertain to the unique nature of pediatric pathology.

Aggressive osteoblastoma: a case report involving a unique chromosomal aberration.

Osteoblastomas are rare bone-producing neoplasms that generally occur in the young and can be misdiagnosed as an osteosarcoma if correlation with clinical history, radiology, and histology is not carefully considered or if the several variants of osteoblastoma are not recognized. These variants lie on a morphologic spectrum between conventional osteoblastoma and osteosarcoma. Aggressive osteoblastoma is one such subtype.

Lymphangiomatosis: a case report.

Lymphangiomatosis is a rare congenital malformation that can involve visceral organs, soft tissue, and bone. This report describes a 5-year-old female with this disorder who presented with respiratory distress and subsequently died. Clinical, diagnostic, and treatment aspects of this entity are discussed.

Medication errors in pediatrics--the octopus evading defeat.

Medication errors have come to the forefront in healthcare and oversight organizations as well as to the public over the past several years. There has been an increasing focus on this area of patient care requiring more intensive evaluation and intervention to prevent these errors. Although it is difficult to ascertain the true occurrence of medication errors, they may occur as frequently as once in every 20 orders.

Sentinel lymph node biopsy in juvenile secretory carcinoma.

A 9-year-old girl presented with a 3-year history of a right breast mass. Excisional biopsy showed a secretory carcinoma. A treatment plan of simple mastectomy and axillary sentinel lymph node biopsy was chosen.

Childhood obesity: a risk factor for omental torsion.

Purpose: To determine the risk factors and clinical presentation of primary omental torsion (POT) in children.

Methods: Histopathology records of a pediatric hospital from January 1993 to March 2003 were reviewed to identify cases of POT. Hospital charts of patients diagnosed with POT were reviewed for demographic data and clinical presentation.

Fatal intravenous injection of potassium in hospitalized patients.

We describe 4 cases of fatal intravenous injection of potassium in the hospital setting. These cases illustrate the subtlety of findings in such deaths and remind the forensic pathologist to consider this type of event in sudden, unexpected death of hospitalized patients.

Sinus histiocytosis with massive lymphadenopathy and Langerhans cell histiocytosis express the cellular adhesion molecule CD31.

Context.-We investigated expression of the adhesion molecule CD31 in sinus histiocytosis with massive lymphadenopathy (SHML) and Langerhans cell histiocytosis (LCH) because (1) SHML and LCH cells express a variety of cellular adhesion molecules and (2) SHML has been characterized as a reactive histiocytic proliferation, and tissue macrophages (histiocytes) are known to express CD31. Objective.
