Actinomycosis of the tongue: a diagnostic challenge.

Actinomycotic infections of the cervicofacial area are rare and frequently show a confusing clinical picture. We report a case of actinomycosis that mimicked a neoplasm of the tongue. The clinical and pathologic features and the differential diagnosis of this unusual oral infection are discussed.

[Histologic microbiopsy with 14 G needle in the diagnosis of breast lesions. Experience with 1000 cases].

PURPOSE: We report our experience with large core biopsy (LCB: 14-Gauge needles) of questionable or suspicious breast lesions detected at mammography and/or US. All biopsies were performed under instrumental guidance. We also report on technique, costs, time, advantages and disadvantages of the method and, finally, give precise indications on when and why large core biopsy is needed. MATERIAL AND METHODS: From january 1996 to may 2000 we performed 1000 microhistologic biopsies on breast lesions at the Unità Integrata di Senologia, Azienda Ospedaliera Careggi, Florence; 650 (65%) were non palpable lesions. Large core needles were used (14-Gauge caliber). In the majority of cases (70%) we used US guidance, in the others a stereotactic guidance was employed. RESULTS: Microhistologic biopsy allowed accurate characterization in most cases. Inadequate samples were obtained in 15 cases. The false negative rate was 6%. Surgery was needed to characterize the lesion unquestionably in 13 cases only. CONCLUSION: In agreement with literature reports, our results confirm large core biopsy as an adequate alternative to surgical biopsy and, to some extent, to FNAC, thanks to its moderate invasiveness, low costs, short execution time, little patient discomfort and high sensitivity (93.98%) and specificity (99.7%).

Laparoscopic decapsulation of a large epidermoid splenic cyst in a child using the UltraCision LaparoSonic Coagulating Shears.

Splenic cysts are rare in pediatric surgery. Congenital epidermoid cysts are exceptional representing only 2.5% of all splenic cysts in childhood. Nowadays, considering the short- and long-term complications of splenectomy in children, the management of epidermoid cyst consists of partial splenectomy or decapsulation of the cystic wall. To our knowledge, the case reported in this article describes the first successful laparoscopic decapsulation of an epidermoid splenic cyst in an 10-year-old child using the UltraCision LaparoSonic Coagulating Shears (LCS). Follow-up at six months confirms no recurrence. Laparoscopic splenic decapsulation provides minimal access and small surgical trauma for treating the cyst while preserving splenic function. The use of UltraCision LCS makes the laparoscopy safely, expeditiously, with minimal blood loss and short hospital stay.

[Proctocolitis caused by Schistosoma mansoni in AIDS. A clinical and immunohistochemical study of a case].

An imported case of intestinal schistosomiasis in AIDS is analysed by the relationships between immune response, diagnostic methods, pathogenetic mechanisms. The inconclusiveness of negative results from both serology and stool parasitology is remarked whereas the efficacy of associated histological, histochemical and immunohistochemical methods is emphasized in order to get better data on aetiological diagnosis and on cell types and size of reactive granulomas. In the case studied, negative serology, absent fecal egg excretion and uneffective granulomatous response with scarcity of T and B lymphocytes have been documented by means of the above methods.

Identification of hematopoietic progenitor cells in human amniotic fluid before the 12th week of gestation.

Due to technical difficulties in performing amniocentesis before the 12th week of pregnancy, very little is known about the components of human amniotic fluid before that time. Amniocentesis was performed between the 7th-11th week of gestation in 25 informed and consenting patients, who had to undergo therapeutic interruption of pregnancy. The cells from the amniotic fluid were stained, counted on a hemocytometer, and checked for vitality. The origin of these cells was determined from cellular cultures the intracellular content of the hemoglobin and the chloroacetate esterase content of the hemoglobin and the chloroacetate esterase contents were also studied. Taking advantage of the "in vitro" adhesive properties of these cells to the bone marrow stromal feeder layer, we obtained clonal growth of an erythroid nature from 18 out of 33 samples. At the 17th week of gestation, an increased number of cells and a decrease in their vitality was found. Between the 7th and 12th week, the cellular composition of the fluid was totally different from that found later in the pregnancy. Small nucleated, round cells were identified as hematopoietic progenitor cells. At the beginning of the 11th week, a cellular population, typically used to perform prenatal diagnosis of chromosomal abnormalities from the 14th week of pregnancy appeared. Since hematopoietic progenitor cells were found in the amniotic fluid before the 12th week of gestation, these cells most probably come from the hematopoietic cells of the yolk sac through the thin membrane of the yolk sac at this time.

Familial AL-amyloidosis in three Italian siblings.

BACKGROUND AND METHODS: Familial occurrence of immunoglobulin-related (AL) amyloidosis has occasionally been reported. In this work we describe the concomitance of systemic amyloidosis and monoclonal gammopathy (one case of Waldenström's macroglobulinemia and two cases without multiple myeloma or related diseases) in three Italian siblings, two males and one female. RESULTS AND CONCLUSIONS: All of them showed a common pattern of polyneuropathy to different degrees; two presented a sicca syndrome and one also suffered from nephropathy. Two of them showed the same HLA typing with the same light chain type (k), but had different presenting symptoms. Polyneuropathy and a history of peptic disease in two cases was suggestive of type III familial amyloidotic polyneuropathy (FAP) occurring in the setting of a familial monoclonal component. However, immunohistochemical studies on different tissue specimens using anti-apolipoprotein A1 and anti-transthyretin antibodies were negative. Further screening of DNA samples for transthyretin (TTR) gene mutations was also negative. Clinical and laboratory investigations ruled out reactive or senile amyloidosis and immunohistochemical studies with anti-light chain antibodies on amyloidotic tissue specimens were positive. As a consequence, this family represents a new case of familial AL-amyloidosis.
