Introduction End-stage renal disease (ESRD) has become a significant problem in the North African region. There are few references about the primary causes of ESRD in kidney transplant (KT) recipients. The aim of this study was to determine the causes of the original kidney disease in KT recipients in Tripoli Central Hospital, Tripoli, Libya. Methods This is a hospital-based, retrospective descriptive study. It includes all KT recipients who were followed up in the outpatient clinic, at the Libyan National General Authority for Organ, Tissue, and Cell Transplantation and nephrology clinic in Tripoli Central Hospital during 2021, Tripoli, Libya. Results Data on 360 KT recipients were retrieved. Sixty-eight percent of the of the patients were males: 31.1% of all enrolled individuals were between 31 and 40 years. Patient mean age was 36.66 ± 11.86 years. The most common validated cause for ESRD was unknown (55.3%), followed by chronic glomerulonephritis (CGN; 15%), diabetes mellitus and systemic hypertension each equally (10.3%), congenital abnormalities (3.6%), polycystic kidney disease (3.3%), and nephrolithiasis (1.9%). Conclusion Original cause of kidney disease in most recipients was undetermined, possibly due to limited diagnostic tools or delayed presentation. However, CGN is a main known cause.

Extramedullary plasmacytoma is a rare plasma cell neoplasm that involves the ovary very rarely. Here, I report a case of primary ovarian plasmacytoma in a 42-year-old patient. The patient presented with abdominal distention, and workup showed a left ovarian mass (6.5 cm x 8 cm) with marked ascites. The patient had a hysterectomy with bilateral salpingo-oophorectomy. Histopathologic, immunohistochemical, bone marrow examination, and other relevant examinations established the diagnosis of primary ovarian plasmacytoma with kappa light chain restriction. No evidence of malignancy in the omentum and ascitic fluid was detected. The patient did not need postoperative chemotherapy or radiotherapy, and 6-month follow-up was uneventful. Due to the scarcity of information on these extremely rare tumors with abdominal masses, the diagnosis should be considered if complete surgical resection is achieved and no evidence of multiple myeloma is found.
