Non-hodgkin malignant lymphoma with tissue neutrophilia: a report of 3 cases

T-cell Lymphoma Presenting Neutrophilic Inflammation in the Cerebrospinal Fluid

A 66-year-old woman presented with upper abdominal pain and weakness in the limbs. She had bilateral uveitis and gastric ulcers. A neurological examination revealed tetraparesis and sensory disturbance in the right arm. A cerebrospinal fluid (CSF) examination showed polymorphonuclear pleocytosis with elevated pro-inflammatory cytokine levels. Magnetic resonance imaging showed brain lesions and a long spinal cord lesion. She was initially diagnosed with neuro-Behçet's disease and was treated with corticosteroids, resulting in no improvement. A gastric mucosa biopsy indicated T-cell lymphoma colocalizing with neutrophils. The cytokine-mediated neutrophilic inflammation probably caused characteristic CSF and histopathological features. It is noteworthy that T-cell lymphoma may present with CSF neutrophilic inflammation.

ALK-Positive Neutrophil-Rich Variant of Anaplastic Large Cell Lymphoma Diagnosed after Head Trauma

BACKGROUND

Anaplastic lymphoma kinase (ALK) expression has not been described in neutrophil-rich anaplastic large cell lymphoma (NR-ALCL).

CASE REPORT

A 12-year old female with a 4-weeks history of a non-resolving bump over the forehead resulting from injury, was diagnosed of stage IE cutaneous T-cell lymphoma, and radiation was employed. Shortly after completion of therapy, there was progress of the disease on the soft tissue of the right hand, and bone marrow involvement was also found. A fine-needle aspiration of the hand mass was performed, and a diagnosis of CD30+/ALK+ NR-ALCL, was rendered.

METHODS

We studied the morphological characteristics of CD30+/ALK+ NR-ALCL using histological methods. A panel of antibodies were used to establish diagnosis and subtyping. In addition EBV status and molecular cytogenetics were determined.

CONCLUSIONS

ALK-ALCL arising in the skin represents a single disease with a broad spectrum of morphology; clinicians and pathologists should be aware of this neutrophil-rich (NR) variant with aggressive clinical presentation.

Invasive ductal carcinoma with tissue neutrophilia: a distinct entity?

Infiltrating ductal carcinoma with tissue neutrophilia in the absence of tumor necrosis or clinical evidence of abscess is a rare and unreported phenomenon. A case report is described with cytomorphologic features of FNA and histopathology with immunohistochemical features.

Paraneoplastic manifestations of lymphoma

Paraneoplastic syndromes are manifestations of malignancies that have produced effects that are distant from the primary tumor or metastases. Paraneoplastic syndromes are not caused by local effects of compression or infiltration into tissues, but are generally due to ectopic hormone production, autoimmune phenomena, or overproduction of cytokines. Paraneoplasia may be the presenting symptom of underlying malignancy and can affect almost any organ system, such as the neurologic syndromes associated with small-cell lung cancer or hypercalcemia associated with squamous cell carcinomas. Lymphoproliferative disorders are also associated with many paraneoplastic disorders; however, to date, most published information has been in the form of case reports and series of small numbers of patients. In this review, the most common paraneoplastic syndromes associated with non-Hodgkin's lymphoma and Hodgkin's disease will be discussed.

Neutrophil-rich Ki-1-positive anaplastic large cell lymphoma: a study by fine-needle aspiration biopsy

Fine-needle aspiration biopsy (FNAB) is an accurate, cost-effective method of evaluating lymphomas. The neutrophil-rich variant of anaplastic large cell lymphoma (NR-ALCL) is a rare non-Hodgkin lymphoma. To our knowledge, we present thefirst study of NR-ALCL by FNAB cytology. Histologic confirmation was available for both patients. Both cases were positive for Ki-1 (CD-30) and were either T-cell or null-cell phenotype. FNAB specimens were highly cellular with a single-cell pattern composed of pleomorphic tumor cells, "hallmark" tumor cells, and a background rich in neutrophils that occasionally obscured tumor cells. Diagnosis on FNAB is difficult owing to the rarity of this tumor, its resemblance to Hodgkin lymphoma and other non-Hodgkin lymphomas that express CD30, its similarity to an infectious process, and its occasional confusion with metastatic carcinoma and melanoma. Reproducible cytologic features usually are present, and the diagnosis can be made conclusively by FNAB in conjunction with ancillary studies.
