ABSTRACT Neutrophil-rich CD30+ anaplastic large-cell lymphoma (ALCL) is a rare pathological entity without distinct clinical behavior. Twelve cases of neutrophil-rich CD30+ anaplastic large-cell lymphoma (ALCL) have been reported, three of them were HIV-infected patients. All these reports stressed the presence of neutrophil infiltration as a new morphologic feature of CD30+ ALCL. Only one case of cutaneous involvement presented with microabscess formation. We describe a case of neutrophil-rich CD30+ ALCL in an AIDS patient with a clinical picture determined by the massive neutrophil infiltration of the tumor without necrosis nor local infection, but with the formation of abscesses.

    ABSTRACT: Cutaneous anaplastic large-cell lymphoma belongs to the class of primary cutaneous CD30-positive lymphoproliferative disorders. The pyogenic variant is marked by a neutrophil rich inflammatory background. We describe 2 cases (one which clinically presented as cellulitis, and another arising in a patient with Hodgkin lymphoma) and review the clinicopathologic features of cases reported in the literature. In all cases, the male to female ratio is 1.2:1. The average age at presentation for patients with this variant is 47 years old with 15% of patients being 25 years old or younger. Thirteen percent of patients are immunocompromized. Ten percent of patients experience extracutaneous disease progression and 18% of patients are dead at 10 months. Immunophenotypically, the anaplastic large cells demonstrate loss of pan-T cell antigens, CD2, CD3, CD5, and CD7, with 65% of cases expressing CD4 and 29% of cases expressing CD8. Epithelial membrane antigen expression is reported in over half of the cases. In the clinical context of a progressive ulcerating lesion in younger or immunocompromized patients, it is important for the pathologist when presented with a skin specimen demonstrating a neutrophil-rich inflammatory background to include the pyogenic variant of anaplastic large-cell lymphoma. We hope to increase awareness of this rare CD30-positive lymphoproliferative disorder subtype by better defining the clinical spectrum in which this entity can present.

    ABSTRACT: Anaplastic large cell lymphoma (ALCL) is a distinct subtype of peripheral T-cell lymphoma (PTCL) characterized by the expression of CD30 in lymphoma cells. Like aggressive B-cell non-Hodgkin lymphoma, the risk of developing PTCL is also increased in the setting of HIV infection. To date, the occurrence of ALCL in HIV-positive individuals is limited to a few case reports and small case series. A total of 37 cases of HIV-associated ALCL were identified after reviewing the available published literature. Analysis of these cases showed that this group of HIV-infected patients was on average 38 years of age with a male-to-female ratio of 4:1, and a reported median CD4 cell count of 83 cells/mm(3). HIV-associated ALCL cells rarely expressed anaplastic lymphoma kinase. Epstein-Barr virus infection was associated with one-third of the cases. These lymphomas manifested almost exclusively with extranodal involvement and exhibited a very aggressive clinical course. The median overall survival was 5 months. The administration of chemotherapy and early stages at presentation were identified as good prognostic factors, while the use of HAART showed a statistical trend toward improved survival in HIV-associated ALCL.
