Partial Nephrectomy Due to Renal Cell Carcinoma in a Patient Who Was a Prior Kidney Donor: Pitfalls About Living Kidney Donation, Case Report, and Review of the Literature.

Cancer development in the remnant kidney in living kidney donors represents a challenging process in terms of patient management. Total nephrectomy is the preferred method for tumors exceeding 7 cm in size. In the case presented here, partial nephrectomy was preferred because the patient was a prior living kidney donor. On the other hand, being an organ donor always creates concerns for long-term safety and survival. The guidelines on the evaluation and care of living kidney donors have generally focused on assessment of the risk for chronic kidney disease in donors and donor-to-recipient infection or cancer transmission. In this case report, we also evaluated whether being a donor is a facilitating factor for cancer development in the remnant kidney.

Nerve sheath myxoma of the upper lip: a case report.

Nerve sheath myxoma is a benign tumor that rarely occurs in the lip area. In this article, a 28-year-old woman admitted with a complaint of painless swelling in the upper lip is presented. The lesion was excised, and histopathological and immunohistochemical examinations were performed. There are only five reported cases in the available literature. Although very rare, nerve sheath myxoma should be considered in the differential diagnosis of lip mass and widely excised to avoid local recurrence. The patient is under clinical control with no signs of recurrence after 16 months.
