Filariasis is a common public health problem in the Indian subcontinent. The diagnosis can be made conventionally by demonstrating microfilaria in peripheral blood smears. Despite its high incidence it is unusual to find microfilariae in fine-needle aspiration (FNA) cytology smears. Microfilariae have been reported in cytological specimens of various organs, but it is extremely rare to find microfilaria in fine FNA cytology of liver. We report seventh case of microfilaria in liver aspirate in a male patient suffering from gallbladder cancer., (Copyright © 2010 Wiley-Liss, Inc.)

We report on 2 patients from Siberia suffering from an infection with the parasite Opisthorchis felineus. The unusual course of their disease pretended in case 1 an eosinophilic leukemia and in case 2 a malignoma of the gallbladder. The Opisthorchiasis is endemic in large areas of Asia and Russia. Humans acquire the infection by eating raw fresh-water fish. Symptoms are nonspecific, but detection of eosinophilia in travellers or residents of endemic areas should induce analysis for specific antibodies against Opisthorchis species. Opisthorchiasis is known to be a precursor of cholangiocarcinoma. Malignoma which was initially suspected could be excluded in both cases and the patients were cured by oral administration of Praziquantel, 40-75 mg/kg body weight for 1 day in 3 divided doses.

A series of 11 patients (3 males and 8 females, mean age 63.4 yrs.) suffering from gallbladder cancer has been reviewed. Authors' purpose in reviewing their experience was to identify factors either in patient characteristics or treatment, that may influence statistic data. Symptoms, signs, laboratory and imaging studies were uniformly unhelpful in determining the diagnosis. Early diagnosis at a stage amenable to surgical excision remains the only therapeutical possibility.

Seventy consecutive gallbladders removed at surgery were examined radiologically and pathologically. Fifteen (21%) of the operative specimens showed naked-eye changes of adenomyomatosis. The main conclusions drawn from this study are that this abnormality is present in a much higher proportion of gallbladders removed at surgery than is generally realised, and that the pathogenesis is primarily an abnormality of muscle contractions, with a strong similarity to diverticular disease of the colon. Diverticular disease of the gallbladder might well be the most appropriate name for this condition. The results of a post-operative clinical assessment of patients with diverticular disease are also presented. But this represents a small number of patients and larger, perhaps multicentre, surveys would be required in order to assess the clinical significance of this interesting abnormality.
