Background: Solitary fibrous tumor can exhibit a broad morphologic spectrum, such as presence of epithelioid tumor cells, adipose cells and multinucleated giant cells. This report describes an unusual morphologic variant characterized by adenofibromatous features, all occurring in the sinonasal region.
Methods: Four cases of the adenofibromatous variant of solitary fibrous tumor were retrieved from the surgical pathology and consultation files in Queen Elizabeth Hospital, Hong Kong.
Idiopathic cervical fibrosis is a rare tumefactive inflammatory-sclerosing lesion involving the soft tissues of the head and neck, and a proportion of patients also have synchronous or metachronous inflammatory fibrosclerosing lesions in other anatomic sites. The latter finding suggests that this entity may represent a member of IgG4-related sclerosing diseases. We report 4 cases to support this postulation.

Here we report a case of splenic tuberculosis associated with monoclonal gammopathy of undetermined significance, and pericarditis. The diagnosis, confirmed by a plugged biopsy of the spleen, precluded the need for splenectomy in this patient and allowed prompt initiation of treatment, thereby avoiding the complications of tuberculous pericarditis and splenic infection.

The main consequence of nodular regenerative hyperplasia of the liver is non-cirrhotic portal hypertension. This condition is probably underdiagnosed, as many of these patients may remain asymptomatic.

Here, we review our experience with TB peritonitis in patients with and without ESRF over a period of 11 years, with special reference to the clinical features of and diagnostic tools for TB peritonitis.
Methods: The records of all patients with TB peritonitis who were seen at United Christian Hospital (Hong Kong) from 1996 through 2006 were reviewed.
