Lynch syndrome is also called Hereditary nonpolyposis colorectal cancer (HNPCC). It is characterized by a risk of colorectal cancer and other cancers of the endometrium, ovary, stomach, small intestine etc. The increased risk is due to inherited mutations that impaired DNA mismatch repair. Two to three percentage of colon cancer is caused by Lynch syndrome. A family history of colon cancer occurs at a young age. We experienced one case of Lynch syndrome who had had stomach cancer, endometrial cancer and colon cancer recently. Hence we report this case with a brief review of literature.

Among the possible complications of radiation therapy, acute and chronic side effects on the skin can be induced by percutaneous radiotherapy in the target site. Common skin lesions include radiation dermatitis, which can be treated by topical application of dressing and ointment. Pemphigoid disease, which displays similar clinical features as other skin diseases such as recurrent cancer and herpes zoster, rarely occurs in the site of radiotherapy; therefore, care must be taken during diagnosis for a timely treatment. The present report is a case of pemphigoid disease that had developed in a patient with endometrioid/clear cell carcinoma after radiation therapy, and the time between onset and radiotherapy was more than 6 months.

Background: Neuroleukemiosis is a rare complication of leukemia. The diagnosis may be delayed owing to non-specific symptoms and the need for special diagnostic modalities. Case: A 70-year-old man in his sixth year of remission from acute myeloid leukemia was referred to the pain clinic for shooting and radiating pain in the left posterior leg. A lumbar spine magnetic resonance imaging showed mild disc bulging of the L2-3, which was insufficient to explain the patient’s symptoms. With insufficient pain response to lumbar epidural block and piriformis injection, we examined both sciatic nerves using an ultrasound and identified an enlarged hypoechoic mass on the left sciatic nerve at mid-thigh level. After that, we biopsied the mass under general anesthesia, and histology confirmed it to be neuroleukemiosis. Conclusions Ultrasound is an inexpensive, non-invasive, simple, and quick diagnostic modality that can be used as a screening tool in the diagnosis of neuroleukemiosis.
