Monoclonal gammopathy of renal significance is a relatively new diagnosis that attributes kidney disease to damage caused by a monoclonal protein. There is growing recognition of this disease in patients previously diagnosed with monoclonal gammopathy of undetermined significance, as they increasingly develop clinically significant renal impairment requiring treatment. We outline a case of a patient presenting with worsening renal function, found to have a circulating monoclonal protein and ultimately diagnosed with a subtype of monoclonal gammopathy of renal significance referred to as immunotactoid glomerulopathy. Abbreviations: MGUS: Monoclonal gammopathy of undetermined significance; M-protein: Monoclonal protein; MM: Multiple myeloma; MGRS: Monoclonal gammopathy of renal significance; MGCS: Monoclonal gammopathy of clinical significance; CKD: Chronic kidney disease; C3 and C4: Complement 3 and complement 4, respectively; EF: Ejection fraction; CT: Computed tomography; IgG: Immunoglobulin G; GFR: Glomerular filtration rate; PET: Positron emission tomography; MRI: Magnetic Resonance Imaging.

Hepatitis is a rare complication of herpes simplex virus (HSV) which can lead to acute liver failure, liver transplant, or death. This complication is more commonly seen in neonates, immunocompromised, or pregnant patients. Early recognition of disease facilitates prompt treatment with antiretrovirals and prevent its progression. To our knowledge, only 30 cases have been reported. Our patient presented with headaches and elevation of transaminases followed by vesicular rash. Culture tested positive for HSV1 and HSV2 and the patient was successfully treated with Acyclovir.
