An uncommon presentation of a common pathogen QUESTION A 70-year-old woman presented with severe spasmodic abdominal pain, nausea, recurrent vomiting and mild diarrhoea. Two months earlier she underwent autologous stem cell transplantation for stage 2A follicular lymphoma. Her medical history was otherwise unremarkable. Physical examination revealed mild epigastric tenderness. Blood tests showed an elevated lactate dehydrogenase (325 IU/L; normal range 135–214 IU/L) and elevated transaminases (alanine transaminase 126 IU/L; aspartate transaminase 90 IU/L; normal range 10–35 IU/L). Blood cell counts were within the normal range. Ultrasound examination did not detect a cause for the abdominal pain. She was not on immunosuppressive therapy. Subsequently, the patient underwent upper endoscopy that revealed the presence of several protruding, ulcerative gastric lesions (figure 1A). The lesions were detected throughout the stomach while oesophagus and duodenum were spared. Biopsies of the gastric lesions were obtained for histological evaluation (figure 1B) and for microbiological analysis. Following 2 weeks of specific therapy, the gastric lesions were no longer detectable (figure 1C, D). What is the most likely diagnosis?

did not test positive for cytomegalovirus, herpes simplex virus, enteroviruses and adenoviruses. Shortly after the endoscopy, the patient developed an itching, blister-like rash as well as thrombocytopoenia of 29 000/mL. A swab test of a skin lesion was sent for virological analysis and tested positive for varicella zoster virus (VZV), and the patient was treated with 1500 mg intravenous aciclovir daily. Subsequently, the biopsies of the gastric lesions tested positive for VZV by PCR. Shortly after treatment initiation, the patient’s abdominal symptoms including nausea and abdominal pain improved notably. The mild diarrhoea persisted and was considered unrelated to the VZV infection following colonoscopy and microbiological analysis of stool samples. After 2 weeks, the ulcerative gastric lesions were no longer detectable. Instead, several mucosal scarifications were observed (figure 1C, D). The patient had previously been exposed to VZV as she had tested positive for VZV-IgG prior to stem cell transplantation. In summary, the patient presented with a gastric manifestation of generalised VZV reactivation including elevated transaminases and thrombocytopoenia.1 As the infection occurred shortly after autologous stem cell transplantation, it was likely associated with an immunocompromised state of the patient. Few cases of intestinal manifestation of VZV infection have been described in the literature, especially in patients with haematological malignancies, with the stomach being the predominant localisation.2–5 Thus, intestinal VZV manifestation should be considered as a possible differential diagnosis, requiring specific virological analysis of gastric biopsies.

ANSWER Histological evaluation of the biopsies revealed ulceration and necrosis as well as nuclear inclusions (figure 1B). The biopsies
