OBJECTIVE To highlight the importance of considering abdominal Lymphoma as a differential diagnosis in the management of obstructive jaundice. METHODS A 51 year old female who presented with abdominal swelling associated with features of obstructive jaundice. Significant findings included jaundice on examination, with abdominal ascites. Laparotomy revealed three litres of icteric fluid. There was a huge left ovarian tumour measuring 14cm x 12cm. Massive peritoneal seedling involved the whole abdomen and pelvis was noted. Following surgery allowing for adequate wound healing, the patient was placed on appropriate chemotherapy. INVESTIGATION/DIAGNOSIS: Histology of excision biopsy revealed high grade Non-Hodgkins's Lymphoma. Screening for human deficiency virus (HIV) was negative. However the erythrocyte sedimentation rate (ESR) was raised at 92 mm Westergren in the first hour. The liver function tests were deranged with total bilirubin of 274 mmol/l and conjugated bilirubin of 204 mmol. serum Ast and Alt were also significantly raised. Total proteins, urea and electrolytes remained essentially within normal limits. The patient was placed on CHOP combination therapy. She attained remission after four cycles of chemotherapy and was discharged home. CONCLUSIONS Abdominal Non-Hodgkin's Lymphoma should be a strong consideration in the management of obstructive jaundice.
