Low grade gastric B-cell lymphoma of mucosa associated lymphoid tissue in immunocompromised patients.

abstract：:Hyaline eosinophilic globules have so far been described in a restricted variety of tumour types. We have noted their presence in a variety of gynaecological malignancies, in particular mixed Müllerian tumours and other epithelial ovarian tumours. We therefore studied their incidence and distribution in a series of ma...
