16 yrs old male was treated successfully due to 1998 diagnosed clinically/cytollogically acute lymphoblastic T leukaemia. FLOW 1998: bone marrow 80% blasts: CD45+, CD8+dim, CD5+, CD2+, CD3+dim, CD7+, HLA-DR+, CD4-, CD1A-, CD10-, CD56-, CD19-, CD34-. In 2004 and 2005 2 lymph node biopsies were diagnosed as "granulomatous lymphadenitis". BM biopsy (2005) was normal. In 2007 lymph node biopsy with similar changes was diagnosed as "periheral T cell lymphoma (with prominent granulomatous response/Lennert variant), NOS". PCR: beta/gama monoclonality. The patient was under steroids only. Any additional chemotherapy was administered. In 2010 bronchial biopsy (due to "organising pneumonia" like opacities) shows necrotic changes with T lymphoid infiltration, probable reactive (biopsy). BM biopsy was normal. And additionally paraspinal tumor with spread to vertebra was diagnosed (back pain, paraparesis, continentio urinae, compression of Th8-Th9). Biopsy was taken. The material was crashed and re-biopsy was taken. Unfortunatelly the re-biopsy was sent to another place (HE and IH photos appended: Courtesy of dr.I.Gudinaviciene). Virtual slides: Apperio. Photos: from virtual slides. HISTO (PARASPINAL): Peringanglial/perineurial interstitial spread of large anaplastic eosinophilic cells (ALCL like) with wrincled, lobated nuclei. HISTO (2004, 2005, 2007 nodes): prominent difusse effacement of architecture, granulomatous background and atypical CD3+ CD4+ infiltrates between granulomas/histiocytes. IH (RESTRICTED) (PARASPINAL): Vimentin+; NSE+/-; PanCK(-); LCA(-); CD3/Pax5/MPO/CD117(-); Synaptophysin/NFP/NB84/CD99/S100(-); Desmin/Myogenin. High Ki67 index ~ 95%. INFECTIONS: any proved (Mycobacteria/Fungi) histochemically. PROPOSAL: 1. Anaplastic large cell lymphoma ALK1 negative: CD3/CD4(-); EMA(-); CD2+; CD30+; ALK1(-). 2. EBV asociated (?) LPL (PTCL or like) in 2004, 2005, 2007. 3. EBV asociated LPL (?) in the lung in 2010. 4. All events after T-LBL treatment (diagnosis not documented) in 1998. SPECIAL QUEST: Syndromic diagnosis of all findings? Nijmegen breakage? Oth? Thankyouforbeeingcloseto.
