Oral cysticercosis--report of six cases.

BACKGROUND: Cysticercosis cellulosae rarely involves the oral region in humans. METHODS: Six cases of oral cysticercosis were diagnosed, three each in lips and buccal mucosa. Diagnosis was made by characteristic gross and histopathologic appearances. RESULTS: Of 146 cases of cysticercosis, 6 (4.1%) were of the oral cavity. All 6 cases were initially seen with painless swellings. Clinical differential diagnosis ranged from retention cyst, lipoma, fibroma, neurofibroma, and angular stomatitis. Histopathologic examination revealed cysticercus larvae. CONCLUSIONS: The oral cavity is a rare site of involvement by cysticercosis, even in an endemic area. Histopathologic findings of the excised cyst are diagnostic of the lesion.

Immunohistochemical expression of c-erbB-2 oncoprotein and EGF-R in pre- and postmenopausal breast cancer.

Tissues from 40 cases each of premenopausal and postmenopausal breast cancer were studied immunohistochemically for epidermal growth factor receptor (EGF-R) and c-erbB-2 oncoprotein. In the premenopausal group, immunopositivity for c-erbB-2 was 15% and for EGF-R 22.5%, whereas in the postmenopausal group, 45% of cases were positive for c-erbB-2 and 42.5% for EGF-R. The difference in immunoexpression of c-erbB-2 between the two groups was significant. A significant correlation was observed between the concomitant expression of c-erbB-2 as well as EGF-R and lymph node involvement. Furthermore, an association was found between c-erbB-2 positivity and histological grading of the tumour. It is interesting that the pattern of the investigated parameters indicates the difference in the pathological events of pre- and postmenopausal breast cancer.

Intra-abdominal lymphangioma--clinicopathological profile of a rare lesion.

Lymphangioma occurring in an intra-abdominal location is reported to be extremely rare. A series of 5 cases is presented and the differential diagnoses and diagnostic features discussed. None of the cases were diagnosed as lymphangioma clinically. It is suggested that their true incidence may be unknown due to both silent clinical course as well as lack of awareness of clinical and morphological features.

Composite carcinoid carcinoma of the colon--a case report.

A composite tumour of the caecum and colon, comprising of distinct areas of classical carcinoid and of well differentiated adenocarcinoma is described. Both components were histochemically confirmed. Presence of a morphologic transition at junctional areas favour a histogenesis from bi-directional differentiation of multipotent precursor cells.

Renal dysplasia with multisystem malformation--a study of 9 cases.

Nine cases of renal dysplasia encountered in a review of necropsy material are described. All these cases had associated major and minor malformations of other systems. Three out of four cases identifying with 'prune belly' syndrome had lower urinary tract obstruction. Three cases fulfilled the criteria of Meckel's syndrome. Three of these six cases, in addition, showed overlapping features with other syndromes. Three cases of unilateral dysplasia with contralateral agenesis had associated anomalies not conforming to any definite combination. We suggest that the association of malformations of developmentally unrelated systems may be random, not sharing any feature except being incompatible with life.

Congenital cystic eyeball.

A rare case of histopathologically proved case of congenital cystic eye in a one day old girl is described. It was an unusually large cystic mass bulging forwards stretching the upperlid. There was no rudimentary eyeball in the orbit. The cystic eye's predilection for the left eye has been pointed out for the first time in this article.

Papillary cystic neoplasm of the pancreas. Report of a case diagnosed by fine needle aspiration cytology.

Fine needle aspiration (FNA) performed on a young woman who presented with a mass in the left hypochondrium yielded fluid. Smears and Cytospin preparations of the fluid showed good cellularity, consisting of relatively monomorphic cells forming a perivascular papillary pattern. FNA cytology thus suggested a diagnosis of papillary cystic neoplasm of the pancreas. Surgical removal of the pancreatic tumor and detailed histologic study confirmed the cytologic diagnosis.
