We report three cases of benign metastasising leiomyoma, which is a rare cause of multiple lung nodules, in three Hong Kong Chinese females. One patient presented with pleuritic chest pain, another was asymptomatic, while the last presented with haemoptysis. All three patients had previously undergone surgical resection of uterine leiomyomas. Multiple lung nodules mimicking lung metastases were demonstrated on chest radiographs, and all three diagnoses were obtained from lung biopsies. Hormonal therapy was given to two patients with variable responses. To the best of our knowledge, this is the first report of benign metastasising leiomyoma in Hong Kong Chinese population. It highlights the importance of considering this rare and benign disease in premenopausal females presenting with multiple lung nodules.

Congenital hepatic fibrosis is an uncommon fibrocystic disorder affecting the intrahepatic bile ducts. It has autosomal recessive inheritance. The main consequence of this condition is portal hypertension and it is often misdiagnosed as cirrhosis. Patients with congenital hepatic fibrosis usually present during childhood or early adolescence with oesophageal variceal bleeding. Portosystemic shunt surgery is the treatment of choice for these patients as the risk of postoperative hepatic encephalopathy is low. We report a patient with congenital hepatic fibrosis who presented with oesophageal variceal bleeding at the age of 16 years, initially misdiagnosed as having cryptogenic liver cirrhosis. The patient experienced two further episodes of oesophageal variceal bleeding in subsequent years. She eventually underwent portosystemic shunt surgery. One year after the operation, the shunt remained patent on Doppler ultrasonography, and there had been no further episodes of variceal bleeding post-surgery.

We report a 38-year-old Chinese woman with lupus nephritis on peritoneal dialysis and long-term maintenance steroid therapy. This patient developed paradoxical deterioration during anti-tubercular therapy for tuberculous lymphadenitis. The deterioration resolved spontaneously without change to pharmacotherapy. Paradoxical deterioration that may spontaneously resolve is a potential complication of anti-tubercular treatment in patients on long-term renal replacement therapy.

Granulocytic sarcomas of the small bowel are rare. They are discrete tumours of leukaemic myeloblasts and partially matured granulocytes that form in any part of the body. This disease is infrequently seen in patients with acute myeloid leukaemia, and rarely seen in patients without leukaemia. Here we report a case of small bowel obstruction due to granulocytic sarcoma of mid-ileum in a non-leukaemic patient. We also review the literature on treatment and prognosis of this condition.

Candida arthritis in patients with a haematological malignancy is rare. We report a case of Candida tropicalis arthritis of the knee that occurred in a patient with acute lymphoblastic leukaemia during the recovery phase of post-chemotherapy neutropenia. Although the Candida tropicalis isolates from synovial fluid and synovial tissue were sensitive to fluconazole in vitro, a 6-week course of oral treatment failed to produce clinical improvement. The arthritis resolved after 7 weeks of combination therapy with caspofungin, a new echinocandin class of antifungal agent that acts primarily on the cell wall. Eleven other reports of Candida arthritis in patients with a haematological malignancy were reviewed.
