Another possibility that can explain the pain is pericarditis. It causes chest pain aggravated by laughing yawning and deep breathing and also causes radiation of pain to arms. Again an EKG, heat echo and chest X-ray is required. I think you should discuss these possibilities with your doctor.
This is due to the confering of such atypia to progeny-cells further down the lineage of that cell type. The term atypia is also used dermatologically and can be a precursor to melanoma. The related concept of dysplasia refers to an abnormality of development, and includes abnormalities on larger, histopathologic, scales.
Definition. Epidermodysplasia verruciformis, otherwise known as, Lutz-Lewandowsky epidermodysplasia verruciformis or Lewandowsky-Lutz dysplasia is a genetic disorder of the skin that is very rare in nature. It is particularly an autosomal recessive genetic disorder, with 10 to 20% of the cases being so. Other cases of epidermodysplasia verruciformis, on the other hand, are predominantly spots that are white in color and very much resembles tinea and pityriasis versicolor, which usually develops in the trunk area. 2  Pityriasis versicolor, by the way, is a pale, rash caused by a yeast-like germ.
