RESUMO
We present a case of an unusually large, circumferential tubulovillous adenoma involving the terminal ileum and the caecum with ileocaecal valve consumption, presenting as intussusception in an otherwise healthy 90-year-old woman. The patient presented with several months of chronic symptoms of weight loss and diarrhoea. Clinical examination revealed a right-sided mass. Investigations revealed a large right-sided lesion suspicious of intussusception. The patient underwent a right-sided hemicolectomy where the intussusception was resected. Histology of the resected mass revealed a tubulovillous adenoma with focal invasive adenocarcinoma.

A 22-year-old man presented with a 1-day history of severe abdominal pain. He developed a generalised vesicular rash 12 h prior to admission. On examination, he was maximally tender with peritonism in the lower abdomen. Working diagnosis was perforated appendix and a decision to investigate with CT was made, which showed intra-abdominal haemorrhage likely arising from a ruptured spleen. After a period of observation, he subsequently underwent laparotomy and emergency splenectomy. Viral PCR from vesicular fluid was positive for varicella zoster virus. Viral serology was otherwise negative.

Myeloid sarcoma is a rare tumour associated with acute myeloid leucaemia (AML). Infrequently, it can occur in myelodysplastic/myeloproliferative overlap syndrome conditions such as chronic monomyelocytic leucaemia (CMML), where it often heralds the transformation towards an AML. We discuss a rare presentation of myeloid sarcoma in the perianal region of a 51-year-old man, who was seen by various clinicians and treated for haemorrhoids and perianal abscess. There were no gross abnormalities in initial haematological investigations and the patient was systemically well. A histological biopsy demonstrated myeloid sarcoma and bone marrow aspirate, and trephine confirmed CMML transforming to AML. Treatment of myeloid sarcoma is dependent on whether there is associated AML in the bone marrow. Dual chemotherapy with cytarabine and daunorubicin remains the gold standard treatment in these patients. Sending histology samples of atypical lesions when performing incision and drainage procedures is extremely important, as it contributes to early detection of rare and malignant tissue diagnoses.
