RESUMO

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare type of T-cell lymphoma of CD3+CD8+ phenotype characterized by deep-seated skin nodules or plaques mimicking panniculitis, a result of neoplastic lymphocytes infiltrating the subcutaneous fatty tissue. We present a case of a 19-month year old boy with SPTCL diagnosed and successfully treated in our institution. Disease first presented with symptoms of high fever and painful erythematous nodule located below the umbilicus. Later on the infiltrates appeared on the face, legs, arms and the back of the body. As the most decisive in obtaining the diagnosis, skin biopsy showed atypical, small to medium-sized lymphatic cells infiltrating the deeper dermal layers as well as the subcutaneous adipous tissue surrounding the adipocytes. Immunohystochemical analysis showed neoplastic lymphocytes positive for CD2, CD3, CD5, CD7, CD8, Tia-1, granzyme B and perforine, and negative for CD20, CD34, TDT and CD56. No infiltration of blood vessels or epidermis was evident. Specific T-cell lymphomas protocol (EURO-LB 02) was then initiated which resulted with rapid regression of all general and local symptoms. The treatment was completed according to schedule and the child is now, 24 months after the initiation of the treatment, in complete remission.

RESUMO

Typical cat-scratch disease (Bartonella henselae infection) in an immunocompetent child is usually associated with a history of scratch, bite or intimate contact with a cat. Most patients develop a non-tender papule in the scratch line after three to ten days. This may persist for only a few days or as long as two to three weeks. During the next two weeks or more, regional lymph nodes that drain the area gradually enlarge and then slowly resolve in more than 10% of patients. The nodes develop overlying erythema and may suppurate. Atypical forms of cat-scratch disease occur in a minority of cases and are characterized by ocular or neurological manifestations, hepatosplenic involvement, vertebral osteomyelitis, endocarditis etc. Immunocompromised individuals with B. henselae infection may develop bacillary angiomatosis, bacillary peliosis, and relapsing bacteremia. There have been several reports of hepatosplenic granulomas caused by B. henselae in immunocompetent children. We report a case of a 6-year-old boy with the hepatosplenic form of cat-scratch disease. Despite early diagnosis and long-term antimicrobial treatment, splenectomy could not be avoided.

RESUMO

High-risk human papillomaviruses (HPVs) are the primary risk factor for developing cervical carcinoma. Hybrid capture II HPV Test (HCII) is a standardized test for molecular detection of HPV DNA in cervical swabs. The aim of the study was to evaluate the clinical utility of the HCII when used in combination with conventional cytology in a group of 171 women who were followed-up with both, cytology and molecular testing for 3 years. At the end of the study, only women positive for high-risk HPV at baseline had retained or worsened cervical intraepithelial neoplasia (CIN). In most women who were negative for high-risk HPV, CIN had resolved within 3 years. These results are in concordance with earlier studies reporting the highly negative predictive value of high-risk HPV testing. Both cytology and high-risk HPV testing provide significant clinical information on the current cervical status of a woman. They should be used in combination for primary screening of CIN, which will provide a more selective and cost-effective follow-up.
