Sinus histiocytosis with massive lymphadenopathy (SHML) (Rosai Dorfman disease) is a disorder first described in lymph nodes but eventually has been described in many organs. Liver involvement is rare and is a great mimicker of infection, metastases or a lymphoma which commonly involve the liver. We describe a case of a middle-aged female who presented with abdominal pain in the emergency. CT scan of the upper abdomen showed multiple hypodense lesions in the liver, pancreas, left sacral ala and multiple enlarged lymph nodes were also noted suggestive of metastases. Excision biopsy revealed the presence of SHML. Since SHML is a great mimicker of other disorders especially malignancy, a high index of suspicion and correlation with tumour markers is necessary to make a correct diagnosis.The excision biopsy was done to identify the nature of the tumour which revealed the presence of SHML.
