ABSTRACT
The histiocytic necrotizing lymphadenitis or Kikuchi-Fujimoto disease is a very rare entity in Spain. We present a 34-year-old arabic male admitted to hospital because one-month story of asthenia, anorexia, weight loss, fever and lymphadenopathies in all palpable sites. Analytic studies were all within normal limits except LDH levels and globular sedimentation rate, both raised. After cervical lymph node biopsy performance high grade Non-Hodgkin lymphoma was initially diagnosed. During admission he complained from pain in both shoulders and an erythematous desquamative eruption in trunk appeared. Some days later, a second lymph node biopsy was performed and Kikuchi-Fujimoto disease was diagnosed. Serologic tests for human herpes virus 6 were positive demonstrating active associated infection. He begun treatment with indomethicin, fever and general symptoms disappeared one week later discontinuing treatment. Two months after discharge, all lymphadenopathies had disappeared. A review on epidemiological, clinical, pathological and differential diagnosis issues is made.

A bone marrow investigation is a common examination in HIV infected patients for the study of cytopenia, febrile syndromes of unknown origin and extension of neoplastic disorders. A study was made of bone marrow specimens from 35 patients with advanced HIV infection (stage IC or C, CDC, Atlanta) for morphologic and culture investigations (aerobes, anaerobes, fungi, and mycobacteria). In nine patients cytopenia accounted for the investigation of bone marrow specimens (9 aspirates and 3 biopsies); in only two cases did the investigation orientate towards a possible etiology: in the first patient a parvovirus B19 infection and in the second patient a hemophagocytic syndrome. In twenty-five patients the bone marrow specimen was studied because of fever of unknown origin (23 aspirates and 10 biopsies) and only in one case was the identification of Mycobacterium tuberculosis obtained. The other patient was studied for lymphoma staging and aspirate and biopsy examinations were normal. A high percentage of patients had eosinophilia, plasmacytosis, increased iron reserves, fibrosis, and changes consistent with myelodysplasia. In conclusion, in our experience the investigation of bone marrow specimen was of little help to clarify the possible etiology of cytopenia and febrile syndromes of unknown origin in patients with advanced HIV infection.

Hodgkin's disease (HD) is not currently accepted as an AIDS diagnostic criterion by the Centers for Disease Control (Atlanta), although there are reports on a higher incidence of the disease in HIV infected patients, with the special feature of a marked clinical and histological aggressiveness. A review of the literature was made and a total of 54 cases of HD compiled of patients with HIV infection. The relationships between the absolute counts of CD4 and the CD4/CD8 ratio with histopathology and with the stage at diagnosis was investigated. No significant differences were found between the absolute counts of CD4 and CD4/CD8 ratio with the clinical stage of disease, histopathologic subgroup or presence of B symptoms in HD. Nevertheless, lower CD4 counts were observed in more advanced clinical stages and in patients with B symptoms; the highest CD4/CD8 ratios were observed in patients with more advanced disease. It is hypothesized that immunological disturbances caused by HIV would lead to more aggressive histological lesions and more advanced stages of HD in HIV-positive patients. Thus, the inclusion of HD as a diagnostic criterion of AIDS would be warranted.
