Johanson--blizzard syndrome.

Johanson-Blizzard syndrome is an extremely rare ectodermal dysplastic disorder characterized by aplasia or hypoplasia of alae nasi, midline scalp defects, growth retardation, varying degrees of mental retardation, hypothyroidism, exocrine pancreatic insufficiency and congenital deafness. This condition is supposed to be an autosomal recessive disorder. We are reporting a female neonate with the characteristic features and an uncommon less emphasized feature viz. cafe-au-lait spots.

A Case of Non-Hodgkin's Lymphoma in a patient with Neurofibromatosis Type 1

Neurofibromatosis type 1 is characterized by cutaneous neurofibromas and pigmented lesions of the skin called cafe au lait spots. Although neurofibromatosis type 1 represents a major risk factor for the development of malignancy, especially of nervous system tumors, malignant lymphoma rarely occurs in a patients with neurofibromatosis type 1. Recently, a 77-year-old woman with neurofibromatosis type 1 was diagnosed as non-Hodgkin's Lymphoma (diffuse large B cell). She had multiple cafe au lait spots, neurofibromas and right axillary lymph node enlargement. An abdominal CT scan demonstrated a left pelvic mass and para-aortic lymphadenopathy. Because non-Hodgkin's Lymphoma in a neurofibromatosis patient has never been reported in Korea, herein, we describe this case and include a review of the literature.
