PURPOSE To identify the CT and MR characteristics of craniopharyngiomas, to evaluate the histologic types of craniopharyngioma, and to compare the radiologic/histologic appearance and type of therapy with tumor recurrence. METHODS We reviewed the records of 45 patients with craniopharyngiomas for which surgical specimens (n = 45), preoperative MR or CT studies (n = 27), or other MR or CT stud...

Multiple or second primary lung cancers can develop at any sites in the lung with same or different histologic types, synchronously and/or metachronously. In case of metachronous occurrence of the second primary lung cancer, it is easy to confuse with the primary lung cancer as a recurrence of precedent lung malignancy treated successfully or metastasis. Previous reports have demonstrated that ...

two cases of multiple concomitant cns tumors of different histologic types are presented.  one was a case of neurofibromatosis type 2 (nf2) with 6 cns tumors, and the other a case of 4 cns tumors without any evidence of nf. to our knowledge, there is no report of concomitant occurrence of 6 cns tumors in the medical literature. neuroradiological  and operative findings are illustrated and discu...

Because few studies have assessed the accuracy of lung cancer histologic diagnoses reported by state cancer registries, we examined whether the Iowa Surveillance, Epidemiology, and End Results Cancer Registry (i.e., the Iowa Cancer Registry)-reported lung cancer histologic diagnoses were reliable. We investigated agreement between lung cancer histologic types reported for 413 patients with lung...

Background: Most data on laser resurfacing have come from studies of people with Fitzpatrick skin types 1 3; however, the world’s population is comprised mostly of Fitzpatrick skin types 4 6, which are more susceptible to post-inflammatory hyperpigmentation (PIH). Objective: For the purpose of expanding the expertise of plastic surgeons treating patients with darker skin types, this study exami...
