Two brothers with infantile myofibromatosis are reported. Both had cutaneous and skeletal myofibromas with spontaneous and complete healing of their cutaneous lesions. These cases suggest autosomal recessive inheritance of this rare disorder.
We describe the MRI features of a rhinoscleroma with orbital extension. This benign bacterial and granulomatous lesion of the paranasal sinuses gave homogeneous low intensity on T2-weighted images and enhanced with gadolinium. It could simulate a malignant sinonasal tumour or a fungal sinusitis; the diagnosis must be considered in patients from endemic areas.
Sister chromatid exchanges (SCEs) were studied in peripheral human leukocytes from 16 patients with balanced translocations or with unbalanced karyotypes, and from 4 controls. No difference was seen between these two groups of people in the mean number of SCEs per cell, or in the total number of SCEs observed for each pair of autosomes involved in the translocations studied. With this last number no difference from the expected number of SCEs, if one supposes that SCEs follow a random distribution, was seen.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
