Pancreatic cancer is one of the most dangerous human cancers and will continue to be a major unsolved health problem as we enter the 21st century. This is the case despite advances in imaging technology and surgical management. Indeed, 80% to 90% of pancreatic cancers are diagnosed either at the locally advanced or metastatic stage. Cutaneous metastases originating from pancreatic cancer are relatively rare. The most common site of cutaneous metastasis is the umbilicus, and this is known as the Sister Joseph's nodule. Very few patients have been reported with cutaneous lesions disclosing a pancreatic carcinoma at sites other than the umbilical area. To the best of our knowledge, there have been no previous reports on cutaneous pancreatic metastasis in Egypt. This is a report on a patient with cutaneous pancreatic metastases at the neck and review of reported non-umbilical cutaneous metastases from pancreatic carcinoma in the literatures.

Background:Alopecia areata (AA) is an immune-mediated form of hair loss that occurs in all ethnic groups, ages, and both sexes. Helicobacter pylori has been associated with many extra-digestive dermatological conditions. The causal relation between alopecia areata and Helicobacter pylori is discussed in this study.Materials and Methods:We have screened for the presence of H. pylori in patients with AA, in order to determine any potential role in its patho-physiology. We have prospectively studied 31 patients with alopecia areata and 24 healthy volunteers of similar gender, for the presence of H. pylori stool antigen (HpSAg).Results:Optical density values for H. pylori infection was positive in 18 of the 31 patients evaluated (58.1%), while in 13 patients, the values did not support H. pylori infection (41.9%). In the control group, 10 of the 24 (41.7%) had positive results. Within the group of alopecia areata, there was no significant difference between HpSAg positive and negative patients.Conclusions:The results have shown that a relation between Helicobacter pylori and alopecia areata is not supported. We advise that H. pylori detection need not to be included in the laboratory work up of alopecia areata.
