Kaposi's sarcoma appeared on a chronically lymphedematous leg of a 75-year-old man. Immunologic investigations revealed a lack of cellular immune response confined to the involved lower limb. Regional disorders of immune surveillance are thought to play an important role in the early stages of Kaposi's sarcoma.

[Ultrasonography of normal vermiform appendix].

The aim of this study was the detection and visualisation of the normal vermiform appendix and its characteristics by ultrasonography in adults with no clinical suggestion of acute or chronic abdominal disease. A prospective study was performed in 200 subjects. The graded-compression ultrasonography technique was used to explore the lower right quadrant of the abdomen and the pelvis. The examination was performed using a 4 MHz sector array and 7.5 MHz linear array transducer. In a few cases, a 10 MHz linear array transducer was used. The appendix was visualized in 54% of patients. In all cases where the appendix was visualized it was found to be either on the ileo-psoas muscle or directly beneath the abdominal wall. The ileo-caecal valve was visualized in 78% of cases. The transverse diameter was found to be no greater than 6.5 mm except in three cases that had a diameters ranging from 7 to 9 mm. Diameter variability along the length of the same appendix was demonstrated in 5% of subjects. Wall thickness was no greater than 2.5 mm. Our experience suggests that graded-compression ultrasonography is a valuable procedure for detecting the vermiform appendix more frequently than has been previously reported. The patients physical constitution and the anatomical location of the vermiform appendix were found to be important factors affecting the ability to visualize the vermiform appendix. The ability to visualise the normal vermiform appendix ultrasonographically supports the clinical diagnosis and excludes acute appendicitis.

Kaposi's sarcoma as clinical manifestation of the acquired immunodeficiency syndrome in a hemophilic patient.

The authors report the natural history of HIV infection in a patient with severe hemophilia A who became HIV-seropositive in 1983 and, four years later, developed full-blown AIDS associated with a disseminated Kaposi's sarcoma. Neutralizing antibody titers against HIV were shown to be inversely disease-associated, while the progression of clinical symptoms was directly related to the decline of T4 cells and the increase of urinary neopterin levels. It is suggested that the presence of an HLA DR 5 phenotype and repeated CMV infection could have been crucial for the development of KS.

[Proteiform syndrome (Proteus syndrome). Skin manifestations in a recently observed case].

The case of a 4-year-old female affected by partial gigantism of the feet, syndactyly and polydactyly, partial right hemihypertrophy of buttock and lower limb, warty hyperpigmented nevus and vulvar lipoma is described. The Authors discuss about the Proteus syndrome, pointing out its rarity, the polymorphism and the problems of differential diagnosis with the Klippel-Trenaunay-Weber syndrome and with other congenital hamartomatous disorders.

Cytodiagnosis of oral pemphigus vulgaris.

A study was undertaken to verify the reliability of the Tzanck test, performed both by traditional cytomorphology and by a direct immunofluorescence technique, for the diagnosis of oral pemphigus vulgaris. Cytologic smears were obtained from oral erosions of 129 patients with various bullous diseases of the oral mucosa, clinically suspected of being oral pemphigus, as well as from 30 healthy subjects. The 40 cases with subsequent histologic proof of oral pemphigus were cytologically diagnosed as such, based on the significant cytomorphologic findings of acantholytic cells or on the pericellular deposition of IgG (which persisted after cytocentrifugation) in epithelial cells, as studied by direct immunofluorescence. Cytomorphology gave positive results in 37 patients with pemphigus and in one patient with a final diagnosis of herpetic stomatitis and gave negative results in all other cases. Immunocytology gave positive results in all patients with pemphigus and negative results in all other cases. The findings indicate that cytomorphologic studies may be useful in screening suspected cases of oral pemphigus vulgaris while the immunocytologic test may provide a reliable definitive diagnosis.
