1/5. Ultrasound diagnosis of oesophagostomiasis.

    Human infection with oesophagostomum bifurcum, a parasitic intestinal helminth, is endemic in parts of West africa. oesophagostomum bifurcum juveniles develop in the colonic wall, causing pus-filled granulomas. The pathology has two distinct forms. Multinodular oesophagostomiasis comprises hundreds of small nodules within a thickened, oedematous wall of the large intestine. Uninodular oesophagostomiasis, called the Dapaong tumour, presents as a painful 30-60 mm granulomatous mass in the abdominal wall or within the abdominal cavity. diagnosis of oesophagostomiasis on clinical grounds alone is difficult. We describe cases illustrating the ultrasound appearance of these two presentations. Multinodular disease shows nodular "target" and "pseudokidney" colonic lesions. The Dapaong tumour is an echo-free ovoid lumen enveloped within a well defined poorly reflective wall. ( info)

2/5. oesophagostomiasis in man: report of the first Malaysian case with emphasis on its pathology.

    This paper describes the first Malaysian case of oesophagostomiasis. The patient was an 8-year-old Malay boy who presented to Ipoh General Hospital, Perak with abdominal pain and weight loss. Examination revealed multiple cavitated pseudotumours of the colon. A hemicolectomy was performed. Examination of the lesions revealed oesophagostomum worms in the necrotic centres. The differential diagnoses and the pathology caused by oesophagostomum are discussed. A brief review of the available literature is presented. ( info)

3/5. Cutaneous oesophagostomiasis in man.

    A case is presented of infection by oesophagostomum, a nematode worm, producing a cutaneous nodule in man. Of the 70 individual cases reported in man it is believed that this is the first in which the worm has produced a lesion outside the gastro-intestinal tract and without evidence of bowel infection. This finding suggests either that the worm is able to achieve direct skin penetration or that it can be disseminated from the bowel via the bloodstream or the lymphatics. The pathology caused by oesophagostomum and the possible modes of infection are discussed in relation to studies in animals, particularly simians and cattle. ( info)

4/5. Rectal bleeding due to oesophagostomum brumpti: report of a case.

    A case of oesophagostomiasis of the large intestine in a black Ethiopian sailor is described. diagnosis was made histologically by finding the parasite in nodules of the intestinal wall. A review of the literature is included. ( info)

5/5. oesophagostomiasis in man.

    A case of oesophagostomiasis in an 8-years-old africa girl is reported. The patient presented with abdominal pain and weight loss. Examination revealed multiple abdominal masses most of which were resected. The difficulties in differential diagnosis are discussed especially with reference to the need for increased awareness of this disease. The extant world literature on this subject is tabulated.
