Voluminous solitary non-Hodgkin extraganglionary lymphoma of thigh.
The case of a 36-year-old woman is presented. She had a voluminous tumour inside the 1/3 average part of the right thigh at 12 cm from the inguinal region. Apart from some local pains, she had a normal haematological formula, normal spleen, liver and lymph nodes. As the tumour of 5.5 x 5 x 4.5 cm was well incapsulated between the sartorius muscle and the great adductor tendon it was easily extirpated and presented a whitish-light yellow section. The histological cellular aspect was pleiomorphic with round, ovalar cells; some were big and clear cells of centroblast-type with several mitoses and giant multinucleated cells and collagenic bundles in between. The nodular Hodgkin sclerosis is not confirmed immunohistochemically because of the negative reaction for antigen Kil (CD30) so that the diagnosis was lymphoma with lymphoma with big B cells by CD20 reaction. We also found positive T cells at CD43 that might be reactive lymphocytes. The tumour ranks a rare malignant lymphoma and for the first time, an extraganglionar lymphoma in thigh was found. We have not met such a location in the literature.
