T-Cell Prolymphocytic Leukemia

T-PLL

To report a case of T-cell prolymphocytic leukemia with panuveitis as the primary presenting feature. Case report. A 46-year-old woman presented with pain and blurred vision in the right eye. [ncbi.nlm.nih.gov]

The immunophenotype CD4 /CD8- is present in 60% of cases, the CD4 /CD8 immunophenotype is present in 25%, and the CD4-/CD8 immunophenotype is present in 15% of cases. Clonal TCR gene rearrangements for the γ and δ chains are typically found. [en.wikipedia.org]

  • Inguinal Mass

    Nine months after his diagnosis of T-PLL, he underwent surgical excision of a new 7 cm left inguinal mass, and was diagnosed with CD30 positive Epstein-Barr Virus (EBV)-associated DLBCL. [ncbi.nlm.nih.gov]

  • Soft Tissue Mass

    Radiologic and physical examination demonstrated an ovoid soft tissue mass of the lateral external auditory canal that, after biopsy and flow cytometry studies, was found to be T-cell prolymphocytic leukemia. [ncbi.nlm.nih.gov]

  • Pharyngitis

    He had a history of pharyngeal diffuse large B-cell lymphoma successfully treated with polychemotherapy including cyclophosphamide and epirubicin, 6 years before the current illness. [ncbi.nlm.nih.gov]

  • Chemosis

    A 57-year-old man presented with bilateral conjunctival hyperemia and chemosis associated with pain. He also complained of having fatigue, general weakness, and disequilibrium. His visual acuity was 20/20 bilaterally. [ncbi.nlm.nih.gov]

    Different combinations of topical lubricants and anti-inflammatory topical eyedrops were prescribed to relieve conjunctival congestion and chemosis, without success. [meajo.org]

  • Conjunctival Hyperemia

    A 57-year-old man presented with bilateral conjunctival hyperemia and chemosis associated with pain. He also complained of having fatigue, general weakness, and disequilibrium. His visual acuity was 20/20 bilaterally. [ncbi.nlm.nih.gov]

  • Subcutaneous Mass

    T-PLL surrounded dermal blood vessels and appendages (n 6), diffusely replaced dermis (n 3), or formed a subcutaneous mass (n 1). Other extramedullary sites included liver and lymph nodes (3 each) and spleen, lung, and cecum (1 each). [ncbi.nlm.nih.gov]

  • Intracranial Hemorrhage

    Patient 39 died suddenly, probably from intracranial hemorrhage, 2 weeks after commencing treatment. The overall response rate was 76%, with 60% CR and 16% PR (Table 2 ). [doi.org]

  • Dysphasia

    An 89-year-old woman who had been treated for Hashimoto's thyroiditis for 20 years presented with a progressively enlarging thyroid mass accompanied by dyspnea and dysphasia. [ncbi.nlm.nih.gov]

  • Cavitary Lesion

    He was admitted to our hospital for chemotherapy and evaluation of a pulmonary cavitary lesion by wedge resection. During sedation, the patient experienced acute respiratory failure and hypovolemic shock, from which he could not be resuscitated. [ncbi.nlm.nih.gov]

  • Gastric Lesion

    Endoscopic examination of the upper gastrointestinal tract revealed hemorrhage from a gastric lesion with histological involvement. [ncbi.nlm.nih.gov]

Only 3 of 9 patients (33%) responded to treatment. Furthermore, 2 of 9 patients (22%) died while on treatment. Recruitment was terminated because of these poor results. [ncbi.nlm.nih.gov]

Patients with very bulky lymph node masses were also more resistant to treatment. [doi.org]

Conjunctival involvement with leukemia was consistent with good visual acuity; however, it portended a poor prognosis. [ncbi.nlm.nih.gov]

Pathophysiology T-PLL is a malignancy of post thymic T-cells with the cytogenetic abnormalities listed above. [cancertherapyadvisor.com]

Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test T-cell neoplasms are relatively uncommon, accounting for approximately 12% of all non-Hodgkin lymphomas. [mayomedicallaboratories.com]
